Creating advanced tactile aids for blind individuals

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This project aims to enhance tactile aids for blind and low vision individuals by utilizing materials chemistry to develop richer tactile sensations, moving beyond traditional physical bumps and textures. The study will evaluate how effectively participants can identify objects made from these innovative tactile materials compared to conventional tactile aids. Key outcomes include the speed of task completion and the variety of categories participants can recognize. By improving the design of tactile aids, the study seeks to increase independence and access to information for visually impaired individuals.
