Detailed Description:
Barcelonas Universal Accessibility Plan 2018-2026 is a commitment by the city to universal accessibility regardless of peoples condition
Currently the mobility problems of visually impaired people are mainly addressed through improvements in the accessibility of the space urban the infrastructures the facilities of use public i until i everything public transport
Is calculated that the missing of autonomy staff generates one cost of more of 15000year for the people visually impaired Also studies show that 40 of visually impaired people fall once a year and 63 of these falls have medical consequences The fear of suffering more falls causes social isolation a sedentary behaviour and consequently a worsening of the quality of life of the psychological state and of health in general especially in the elderly 10 of which can develop severe depression
BCNMob project wants to contribute to reverse this situation a thorough analysis and the measure of improving the mobility and universal accessibility of people with visual impairments in the city of Barcelona through the development of devices with 5G technology in combination with artificial vision and augmented reality integrated with the systems of Barcelona City Councilampampampampamp39s Open Data to inform users in real time
The solution proposed by BCNMob is conceived from a perspective of collective and integrated use in the city through a device sharing system that allows providing a mobility service adapted to the disability visual a so many people come be it possible following one philosophy similar at service of Bicing
B OBJECTIVES OF PROJECT AND QUESTIONS INVESTIGATION
The aim of the BCNMob project is to carry out a pilot study to analyse and measure the improvement of mobility and universal accessibility of people with visual impairments that can be achieved in the city of Barcelona through the use of technology 5G in combination with other technologies such as artificial vision and augmented reality
Nowadays the mobility problems of visually impaired people are mainly addressed through improvements in the accessibility of the space urban the infrastructures the facilities of use public i until i everything public transport Despite the undeniable usefulness of these measures these actions do not allow by themselves the full mobility of these people that they follow requiring of accompaniment for the carrying out the majority of their journeys and who suffer from a strong dependence as a result of the lack of autonomy staff see more forward the section of Impact Social How much the relationship of this problem with the objectives of the call it must be taken into account that due to the progressive nature of most of its causes visual impairment affects the vast majority in the elderly so according to WHO data 80 of people who suffer from visual impairment are over 50 years old
The project BCNMob pretends to change the shape to address this one problematic posing more accent in the improving the ability of visually impaired people to move around like other people allowing them to overcome by themselves the possible barriers that could limit their mobility and access to public spaces and services However the solution is conceived from a perspective of collective and integrated use in the city through a system of sharing devices that allows providing a mobility service adapted to the visual impairment to as many people as possible following a similar philosophy at service of Bicing This one study will allow the validation of this technology come a possible solution that give answer to the requirements deployed by new Code of Accessibility of Catalonia expected for this year 2022 and is aligned with the Barcelona Strategy for Universal Accessibility which identifies the need to emphasize improvements in communicative accessibility visual sensory and cognitive
To carry out the BCNMob project the investigators will use technology developed by BIEL GLASSES SL see details in the technology section This technology has already been analysed and validated by the UPC in laboratory Movilab of the faculty of Optics i optometry of terrace see removed of methodology later The Mobile World Capital foundation has selected Biel Glasses to carry out a first test of this technology during the month of July of this year the cities of Reus i Tarragona come a case benchmark of how 5G technology can help people with disabilities and has been awarded by the Agency Spatial European come one of the projects with greater potential that ago us of the European space technology
The goals of the BCNMob project are much more ambitious both from a technological point of view and from the analysis of the impact on the city and its inhabitants So the investigators intend to move forward during the project in development of the state current of the technology for such to improve it the functionality adding capacity of navigation adapted to people with visual impairments The investigators also want to advance integration with the city itself both technologically and socially technologically through access to Open Data information relevant for the mobility of the people with disability visual i with the training of system of AI to recognize the signage used in Barcelona at a social level through the realization of a first experience on an international scale of a device sharing system for improving autonomy of these people front page a term in collaboration with the fabric associative represented for the Foundation period of view entity integral of the table of accessibility of the network for the life Independent XAVI from Barcelona Finally the UPCampampampampamp39s leadership will allow a scientifically accurate study to be carried out of the improvement achieved in mobility within the city and the accessibility of public spaces

Design of the tests The design of the tests foresees one first phase for do essays in spaces exteriors sure for the users which will include sufficient elements relevant to mobility obstacles crossings etc Afterwards the assessment will be made in spacesroutes selected by the user with the aim of assessing the level of impact of the mobility solution on their day-to-day life In this phase safety will be provided by accompanying a sighted guide A coordination system will be designed between the escort and the user that allows the escort to stop the user before any situation of risk without that this change the headquarters movement free i self-employed for such of to allow to evaluate the improvement obtained
determination of the variables of study i of headquarters register Systems will be implemented to control the parameters to be measured both subjective through the creation of surveys adapted to the study and objective For the various types of tests quality markers KPIs will be defined such as walking speed recognition of the existence of obstacles increase in distances travelled autonomously decrease of hours of accompaniment i also the measure of accessibility to certain equipment system usability etc This information will be collected through user surveys
PHASE 2 recruitment of the candidates i the candidates
- Diffusion of the study and contact with the possible candidates For the dissemination of the study the investigators will use online and offline actions Regarding online actions the study will be published in the respective pages web of the entities that they form the consortium Also will be used the social networks The Punt de Vista Foundation is very active on social networks 2000 followers and speaker on various community platforms and will coordinate the online dissemination of the BCNMob project in its various stages how much the shares offline the UPC will put in communication of the people candidates between the users of the unity of come down vision of Centre university of the vision where they receive attention patients that
they gather the requirements for participate in the project on the other band the Foundation period of view will spread the call between the professional community College of Optics i optometrists patron Spanish Society of Baja Specialists Visión etc health sector IMO Sant Joan de Déu Sant Pau Dr Díaz patron etc social sector and affected organizations Associació Discapacitat Visual Catalunya B1B2B3 patron Retina Catalunya ACIC etc and networks public Xavi advice sectoral of people with disability etc All these actions will be carried out respecting data protection legislation avoiding unauthorized and indiscriminate communications at all times
- Characterization of the parameters visuals i functional of the participants with the goal of to determine the profile visual theirs needs of mobility i the implications of acceptance of the solution technological to the participants the study know them will perform one assessment visual functional binocular of visual acuity visual field contrast sensitivity glare recovery time and color vision as well as the collection of information on the present time of the disability and the reflex in the resolution of activities of daily living
PHASE 3 development i integration
technology object of the study The technology that aims to evaluate the project BCNMob is developed for BIEL GLASSES SL This company is the result of the initiative of the parents of Biel a child with congenital visual impairment who suffers from mobility limitations as a result of his disability His parents a doctor and an electronic engineer decided to start the project when they saw that there were no solutions on the market that would allow Biel to move around the city autonomously and safely
The system is based on a device consisting of smart glasses that solve the usersampampampampampamp39 mobility problems using a combination of the most advanced technologies AI - Artificial Intelligence robotics XR- reality extended 5G i geolocation Galileo These glasses are able to understand reality and adapt it to the userampampampampampamp39s ability to perceive for such that can move around of shape autonomous The device detects mobility risks such as obstacles steps holes pedestrian crossings or traffic lights and uses XR for insert in the image directions graphics adapted to the remaining vision of each patient In addition the system incorporates a navigation system of high accuracy based on in the combination of AI i the system of Galileo positioning which provides directions adapted in the same way In the following video one can see an explanation of how the device workshttpsvimeocom465500260
The device uses 5G technology to connect to the platform at cloud for such of power bring a term the high computational load processes that are required The large bandwidth of 5G and its low latency make it possible to do these tasks in the cloud without reduce the quality of the image and reaction times which is absolutely critical in an application come this one The consequent reduction of the load of the local processor of the device allows reducing its consumption of energy the weight the size i the cost For reduce even more latency technology is used which brings the infrastructures closer together of computation the border of the network 5G The fault-tolerant design maintains the ability to locally perform safety-critical functions such as obstacle detection in the event of a 5G connection loss
The 5G connection allows also the access resources in line come bases of cartographic data necessary for the navigation In this one meaning come a party of project it foresees to include the integration of system with the platform Open date BCN for such to access an information updated about works have to place the city of Barcelona that they can make it difficult the displacement of the users The system will use this one information both to warn users when they are approaching and to calculate routes so that they can be avoided Thank you at headquarters design based on in XR the system no only is capable of to provide directions adapted to the userampampampampamps visual capacity but also allows working on the image itself to offer visual improvements such as zoom vision or dynamic light adaptations to avoid glare and night blindness very common in people with problems of peripheral visual field
The solution includes a platform also based on the cloud that allows that the devices be used by multiple users by automatically downloading the configuration of each of them The configuration for each patient is performed only once by one optometrist this allows to get the maximum performance of the vision that the user retains From then on the system stores this configuration to be downloaded to any device that the user person needs to use The system provides for the use of cabins of collection and deliver sanitized for the which thing the model of use shared of devices may be implemented in urban areas by public health systems social services or associationsfoundations related with the disability visual The delivery of the device39s address can also be implemented according to the preferences and capabilities of the institutions providing the service including the sanitation process
- Tests Before using the device with users the investigators will perform validation tests of the device39s technical functions in the MoviLab laboratory environment
- Methodology of management of project technological This phase includes the development and integration tasks that must allow the use of the technology developed by BIEL GLASSES for the realization of the BCNMob project These tasks make up one project technological inside of project general of pilot i in consequence for bring it a term the investigators will use project management methodology to achieve the planned objectives within the pre-established term i with budgeted costs The management team of project will maintain communication between all interested parties in the project and identify deviations in the Project Plan with respect to its development in the three slopes of the management of projects scope of realization or reach of goals execution term and costs incurred during everything the project is will last a term one tracking of same with the aim of coordinating the work of the different teams involved compiling all the results obtained determining the decisions to be made at each stage of the project and establishing the appropriate priorities
Likewise will take care of maintenance of the documentation generated in the project including the reports and correspondence He will also draw up the meeting minutes of the Project Management Committee and keep the rest of the researchers informed both from his own group and of the collaborators The meetings of the Project Management Committee will be convened periodically in order to monitor and verify the fulfilment of its objectives to correct any deviations that may have arisen and to plan the work to be carried out according to the planning established temporary Risk management will also be one of the fundamental parts of the Project Management Committee During execution of project for a minimize anyone risk additional no expected they will identify themselves some of the more risks important of project i the headquarters possible plan of contingency The responsible for project will be the person in charge of the evaluation continuous of the management of risk like that come of the update of the analysis of risks and of plan of contingencies depending on the results that are consumed during the project The risk management plan for the project is shown in the adjacent figure
In relation to the software development that is necessary for the adaptation of the technology to the objectives of the pilot study SCRUM methodologies will mainly be used
PHASE 4 execution of pilot
Shares formative
The investigators will three type of shares trainings
- Training of the people companions guides seers for to allow the coordination with the user person during the tours for to manage the risks without alter the headquarters movement free i autonomous and facilitate the evaluation of the improvement obtained
Training in the usability of the devices for people users i technicians
Operation of the platform of use shared to the people users companions and technicians
Tests of mobility i universal accessibility How it has indicated previously for the execution of this phase will be used the methodology developed by the Principal Investigator in her doctoral thesis modified during the design phase in order to adapt it to the requirements of the proposed study A noteworthy aspect of this methodology is the use of observers simulators The observers simulators they are people with vision normal that they use simulation systems to restrict their vision similarly to that of the visually impaired The participation of these people will allow doing one validation of the areas of tests before of the participation of the members of the study cohort This validation includes both the aspects related to the relevance and adequacy of the tests with respect to the indicators a measure come the safety of the members of the cohort The results obtained will serve to make adjustments or improvements in the design of the study
PHASE 5 analysis of the tests carried out
- Analysis i conclusions of the results obtained They will be analysed so much the results measurable of shape objective reduction of collisions reduction of the time required to complete the routes etc as well as the subjective opinions of the users satisfaction usability of the system etc
- Proposal of improvements in the system
PHASE 6 Shares of disclosure to see removed specific of Actions of disclosure section J Projects network communication as well as the creation of associated audiovisual resources will be carried out by Silvia Martín communication technician at the Punt de Vista Foundation
D RESULTS The investigators hope that the results of the study will allow us to confirm an increase in the autonomy of visually impaired people who use the system of at least 85 measured as the increase in routes that is they can perform of shape autonomous this one indicator will form party of one set a lot more complete that must allow measuring and where appropriate validate the usefulness of technology both to improve mobility and the accessibility of urban spaces The investigators also hope to extend the current functionalities of the system including the capacity of navigation adapted i the integration with the information ampampampampampamp34Open dateampampampampampamp34 offered by Barcelona City Council to be able to provide full autonomy to users Finally the investigators hope to validate the usability reliability and security of the technology to the point where the investigators can ensure the success of a potential deployment
For that ago the citizenship these results they have of to allow advance in the development i deployment of technologies that allow the improvement of mobility and the quality of life of people with visual impairments especially of the people great that in suffer that in they are the big majority of the affected These people add to the mobility and quality of life problems generated by visual impairment their own physical and social fragility can lead to more severe consequences when accidents or disorientation occur such as social isolation caused by the fear of suffering which significantly impacts their quality of life see the Social Impact section
For that ago the decisions policies is clear that these they will be necessary for materializing the advances that can facilitate the technology i too it will be that is they can to take of shape grounded the investigators wait that the results of the study provide sufficient evidence to consider this technology among the options a have in account for the improvement of the mobility and the quality of life of the people with visual impairment a Barcelona with special attention the people great affected In specific the investigators wait that the results are they can to have in account in the implementation of the Strategy Barcelona for Accessibility universal 2022-2030 and to comply with the next Accessibility Code of Catalonia
Regarding knowledge it is important to bear in mind that this technology is fully developed in Barcelona by a company that is also being incubated by Barcelona Activa having been selected to participate in several programs of this entity as an of the projects with major potential so much at a technological level like social it is of course the results of this project will contribute in form decisive the improvement i validation of this technology and am the consolidation of the company i that the results of this study they will serve of reference a level international for the possible extension an others cities of Europe and beyond contributing at growth of Barcelona come a referent technological i too at growth of technological sector in areas of maximum interest for its innovation such as artificial intelligence extended reality applications of 5G networks and robotics
E CHRONOGRAPH
Below is the work plan in its various phases associated tasks and responsibilities UPC for Universitat Politècnica de Catalunya BG for Biel Glasses SL and PDV for the Punt de Vista Foundation and the schedule
I JUSTIFICATION OF THE ADVANTAGES FROM LA COOPERATION OF THE APPLICANTS BCNMob project team is made up of experts in the fields of optometry medicine technology scientific dissemination and management which together bring more than 50 years of experience in the field of Information Technologies and 30 years in medical research and visual health
The achievement of the objectives that is raises the project BCNMob is possible only thank you to the synergies generated between the three entities that make up the consortium Their complementarity is based on the areas of contrasting expertise of each and on the history of previous collaborations between the three organizations and constitutes the starting point of the BCNMob project its main asset and the added value of the initiative
J IMPACT SOCIAL FROM LA RESEARCH
For a understanding the impact social i economic of project BCNMob about the people with come down vision BV it is necessary to understand the impact that mobility problems have on these people and that can be divided into tangible and intangible aspects Here are the tangibles
- The missing of autonomy carries problems of dependency
- From the labour point of view mobility problems mean that the offer of jobs to people with disabilities visual be in the immense majority places that no they involve mobility the which thing reduces supply and has an impact on a very high unemployment rate over 75 in 2019 according to data from the European Blind Union
- Lack of autonomy combined with deteriorating health see intangible effects below can behave in the institutionalization of the person the which thing is a lot expensive and involves other risks as demonstrated by the COVID-19 pandemic
Economically existing estimates calculate the combined impact of tangible aspects at approx 15000yearperson a Europe 1 costs adjusted to the inflation being the costs of dependence and institutionalization the highest
The aspects of intangibles still that no less important include the following
The mobility reduced implies the incapacity to maintain and generate relationships outside of one environment local i the close family circle causing social exclusion
Currently the mobility problems of visually impaired people are mainly addressed through improvements in the accessibility of the space urban the infrastructures the facilities of use public i until i everything public transport
Is calculated that the missing of autonomy staff generates one cost of more of 15000year for the people visually impaired Also studies show that 40 of visually impaired people fall once a year and 63 of these falls have medical consequences The fear of suffering more falls causes social isolation a sedentary behaviour and consequently a worsening of the quality of life of the psychological state and of health in general especially in the elderly 10 of which can develop severe depression

- Characterization of the parameters visuals i functional of the participants with the goal of to determine the profile visual theirs needs of mobility i the implications of acceptance of the solution technological to the participants the study know them will perform one assessment visual functional binocular of visual acuity visual field contrast sensitivity glare recovery time and color vision as well as the collection of information on the present time of the disability and the reflex in the resolution of activities of daily living
PHASE 3 development i integration
technology object of the study The technology that aims to evaluate the project BCNMob is developed for BIEL GLASSES SL This company is the result of the initiative of the parents of Biel a child with congenital visual impairment who suffers from mobility limitations as a result of his disability His parents a doctor and an electronic engineer decided to start the project when they saw that there were no solutions on the market that would allow Biel to move around the city autonomously and safely
The system is based on a device consisting of smart glasses that solve the usersampampampampampamp39 mobility problems using a combination of the most advanced technologies AI - Artificial Intelligence robotics XR- reality extended 5G i geolocation Galileo These glasses are able to understand reality and adapt it to the userampampampampampamp39s ability to perceive for such that can move around of shape autonomous The device detects mobility risks such as obstacles steps holes pedestrian crossings or traffic lights and uses XR for insert in the image directions graphics adapted to the remaining vision of each patient In addition the system incorporates a navigation system of high accuracy based on in the combination of AI i the system of Galileo positioning which provides directions adapted in the same way In the following video one can see an explanation of how the device workshttpsvimeocom465500260
The device uses 5G technology to connect to the platform at cloud for such of power bring a term the high computational load processes that are required The large bandwidth of 5G and its low latency make it possible to do these tasks in the cloud without reduce the quality of the image and reaction times which is absolutely critical in an application come this one The consequent reduction of the load of the local processor of the device allows reducing its consumption of energy the weight the size i the cost For reduce even more latency technology is used which brings the infrastructures closer together of computation the border of the network 5G The fault-tolerant design maintains the ability to locally perform safety-critical functions such as obstacle detection in the event of a 5G connection loss
The 5G connection allows also the access resources in line come bases of cartographic data necessary for the navigation In this one meaning come a party of project it foresees to include the integration of system with the platform Open date BCN for such to access an information updated about works have to place the city of Barcelona that they can make it difficult the displacement of the users The system will use this one information both to warn users when they are approaching and to calculate routes so that they can be avoided Thank you at headquarters design based on in XR the system no only is capable of to provide directions adapted to the userampampampampamps visual capacity but also allows working on the image itself to offer visual improvements such as zoom vision or dynamic light adaptations to avoid glare and night blindness very common in people with problems of peripheral visual field
The solution includes a platform also based on the cloud that allows that the devices be used by multiple users by automatically downloading the configuration of each of them The configuration for each patient is performed only once by one optometrist this allows to get the maximum performance of the vision that the user retains From then on the system stores this configuration to be downloaded to any device that the user person needs to use The system provides for the use of cabins of collection and deliver sanitized for the which thing the model of use shared of devices may be implemented in urban areas by public health systems social services or associationsfoundations related with the disability visual The delivery of the device39s address can also be implemented according to the preferences and capabilities of the institutions providing the service including the sanitation process
- Tests Before using the device with users the investigators will perform validation tests of the device39s technical functions in the MoviLab laboratory environment
- Methodology of management of project technological This phase includes the development and integration tasks that must allow the use of the technology developed by BIEL GLASSES for the realization of the BCNMob project These tasks make up one project technological inside of project general of pilot i in consequence for bring it a term the investigators will use project management methodology to achieve the planned objectives within the pre-established term i with budgeted costs The management team of project will maintain communication between all interested parties in the project and identify deviations in the Project Plan with respect to its development in the three slopes of the management of projects scope of realization or reach of goals execution term and costs incurred during everything the project is will last a term one tracking of same with the aim of coordinating the work of the different teams involved compiling all the results obtained determining the decisions to be made at each stage of the project and establishing the appropriate priorities
Likewise will take care of maintenance of the documentation generated in the project including the reports and correspondence He will also draw up the meeting minutes of the Project Management Committee and keep the rest of the researchers informed both from his own group and of the collaborators The meetings of the Project Management Committee will be convened periodically in order to monitor and verify the fulfilment of its objectives to correct any deviations that may have arisen and to plan the work to be carried out according to the planning established temporary Risk management will also be one of the fundamental parts of the Project Management Committee During execution of project for a minimize anyone risk additional no expected they will identify themselves some of the more risks important of project i the headquarters possible plan of contingency The responsible for project will be the person in charge of the evaluation continuous of the management of risk like that come of the update of the analysis of risks and of plan of contingencies depending on the results that are consumed during the project The risk management plan for the project is shown in the adjacent figure
In relation to the software development that is necessary for the adaptation of the technology to the objectives of the pilot study SCRUM methodologies will mainly be used
PHASE 4 execution of pilot
Shares formative
The investigators will three type of shares trainings
- Training of the people companions guides seers for to allow the coordination with the user person during the tours for to manage the risks without alter the headquarters movement free i autonomous and facilitate the evaluation of the improvement obtained
Training in the usability of the devices for people users i technicians
Operation of the platform of use shared to the people users companions and technicians
Tests of mobility i universal accessibility How it has indicated previously for the execution of this phase will be used the methodology developed by the Principal Investigator in her doctoral thesis modified during the design phase in order to adapt it to the requirements of the proposed study A noteworthy aspect of this methodology is the use of observers simulators The observers simulators they are people with vision normal that they use simulation systems to restrict their vision similarly to that of the visually impaired The participation of these people will allow doing one validation of the areas of tests before of the participation of the members of the study cohort This validation includes both the aspects related to the relevance and adequacy of the tests with respect to the indicators a measure come the safety of the members of the cohort The results obtained will serve to make adjustments or improvements in the design of the study
PHASE 5 analysis of the tests carried out
- Analysis i conclusions of the results obtained They will be analysed so much the results measurable of shape objective reduction of collisions reduction of the time required to complete the routes etc as well as the subjective opinions of the users satisfaction usability of the system etc
- Proposal of improvements in the system
PHASE 6 Shares of disclosure to see removed specific of Actions of disclosure section J Projects network communication as well as the creation of associated audiovisual resources will be carried out by Silvia Martín communication technician at the Punt de Vista Foundation
D RESULTS The investigators hope that the results of the study will allow us to confirm an increase in the autonomy of visually impaired people who use the system of at least 85 measured as the increase in routes that is they can perform of shape autonomous this one indicator will form party of one set a lot more complete that must allow measuring and where appropriate validate the usefulness of technology both to improve mobility and the accessibility of urban spaces The investigators also hope to extend the current functionalities of the system including the capacity of navigation adapted i the integration with the information ampampampampampamp34Open dateampampampampampamp34 offered by Barcelona City Council to be able to provide full autonomy to users Finally the investigators hope to validate the usability reliability and security of the technology to the point where the investigators can ensure the success of a potential deployment
For that ago the citizenship these results they have of to allow advance in the development i deployment of technologies that allow the improvement of mobility and the quality of life of people with visual impairments especially of the people great that in suffer that in they are the big majority of the affected These people add to the mobility and quality of life problems generated by visual impairment their own physical and social fragility can lead to more severe consequences when accidents or disorientation occur such as social isolation caused by the fear of suffering which significantly impacts their quality of life see the Social Impact section
For that ago the decisions policies is clear that these they will be necessary for materializing the advances that can facilitate the technology i too it will be that is they can to take of shape grounded the investigators wait that the results of the study provide sufficient evidence to consider this technology among the options a have in account for the improvement of the mobility and the quality of life of the people with visual impairment a Barcelona with special attention the people great affected In specific the investigators wait that the results are they can to have in account in the implementation of the Strategy Barcelona for Accessibility universal 2022-2030 and to comply with the next Accessibility Code of Catalonia
Regarding knowledge it is important to bear in mind that this technology is fully developed in Barcelona by a company that is also being incubated by Barcelona Activa having been selected to participate in several programs of this entity as an of the projects with major potential so much at a technological level like social it is of course the results of this project will contribute in form decisive the improvement i validation of this technology and am the consolidation of the company i that the results of this study they will serve of reference a level international for the possible extension an others cities of Europe and beyond contributing at growth of Barcelona come a referent technological i too at growth of technological sector in areas of maximum interest for its innovation such as artificial intelligence extended reality applications of 5G networks and robotics
E CHRONOGRAPH
Below is the work plan in its various phases associated tasks and responsibilities UPC for Universitat Politècnica de Catalunya BG for Biel Glasses SL and PDV for the Punt de Vista Foundation and the schedule
I JUSTIFICATION OF THE ADVANTAGES FROM LA COOPERATION OF THE APPLICANTS BCNMob project team is made up of experts in the fields of optometry medicine technology scientific dissemination and management which together bring more than 50 years of experience in the field of Information Technologies and 30 years in medical research and visual health
The achievement of the objectives that is raises the project BCNMob is possible only thank you to the synergies generated between the three entities that make up the consortium Their complementarity is based on the areas of contrasting expertise of each and on the history of previous collaborations between the three organizations and constitutes the starting point of the BCNMob project its main asset and the added value of the initiative
J IMPACT SOCIAL FROM LA RESEARCH
For a understanding the impact social i economic of project BCNMob about the people with come down vision BV it is necessary to understand the impact that mobility problems have on these people and that can be divided into tangible and intangible aspects Here are the tangibles
- The missing of autonomy carries problems of dependency
- From the labour point of view mobility problems mean that the offer of jobs to people with disabilities visual be in the immense majority places that no they involve mobility the which thing reduces supply and has an impact on a very high unemployment rate over 75 in 2019 according to data from the European Blind Union
- Lack of autonomy combined with deteriorating health see intangible effects below can behave in the institutionalization of the person the which thing is a lot expensive and involves other risks as demonstrated by the COVID-19 pandemic
Economically existing estimates calculate the combined impact of tangible aspects at approx 15000yearperson a Europe 1 costs adjusted to the inflation being the costs of dependence and institutionalization the highest
The aspects of intangibles still that no less important include the following
The mobility reduced implies the incapacity to maintain and generate relationships outside of one environment local i the close family circle causing social exclusion
