Summary

This study looks at how blind people use a white cane to sense the world around them, not just to move. Researchers will test how well users can feel where a touch happens on the cane and measure brain activity during these tasks. The goal is to understand how the cane becomes an extension of the body. The study involves 300 adults, both blind and sighted, and includes EEG and brain scans.
