Brief Summary:
The objective of this project is to create richer tactile aids by using materials chemistry to create tactile sensations in tactile aids as an alternative to traditional physical bumps lines or textures These materials are commonly used in household products but have not yet been used to enrich tactile aids Successful outcomes are primarily the accuracy with which low vision or blind subjects identify objects made from tactile coatings versus traditional tactile aids Other outcomes include time to completion of the task or the number of distinctive categories that participants can identify
Detailed Description:
Traditional images and graphics like mathematical plots or charts are not accessible to low vision and blind people Instead for blind and low vision people tactile aids are traditionally used to convey abstract concepts However tactile aids cannot convey as rich or as dense of information as traditional visual graphics limiting independence and access to gainful employment for low vision and blind professionals
The primary reason why tactile aids are inferior to visual graphics is that tactile aids are made from a combination of physical bumps lines and labels Placing too many details on a single tactile aid quickly becomes illegible to the user because the various bumps lines and textures blur together which is known as tactile clutter
The objective of this project is to create richer tactile aids by using materials chemistry to create tactile sensations in tactile aids as an alternative to traditional physical bumps lines or textures These materials are commonly used in household products but have not yet been used to enrich tactile aids Successful outcomes include having low vision or blind subjects identify objects made from our tactile materials quicker than traditional tactile aids or to successfully identify more categories on a mathematical plot than is currently possible with existing tactile aids
