ClinConnect Summary

This clinical trial is exploring new types of tactile aids designed for people who are blind or have low vision. The goal is to improve the way these aids feel, making it easier for users to identify different objects. Instead of just using simple bumps and textures, the researchers are trying out special materials that can create more interesting and varied sensations. This study will measure how accurately participants can recognize objects and how quickly they can complete tasks with these new aids compared to traditional ones.

To participate, individuals must have been blind or visually impaired for more than 10 years and should regularly use tactile aids. A basic understanding of shapes and graphs, similar to high school geometry, is also required. However, people with conditions that affect their hand use will not be eligible. If you join the trial, you can expect to work with new tactile materials and contribute to research that could help improve daily living for those with visual impairments. The trial is currently looking for participants of all ages who meet the criteria.
