IIT Kanpur develops touch sensitive watch for visually impaired

A professor and a research associate of Indian Institute of Technology (IIT) Kanpur have developed a sensitive watch for the use of visually impaired people. The watch has tactile hour indicators of different shapes. These indicators help the visually impaired persons to recognize the time easily.

About the Touch Sensitive Watch

The user has to touch and scan the hour indicator of the watch to know the time. The watch then communicates back to the user with the help of different vibration patterns. The watch provides user privacy as it does not require audio feedback.

Currently, mechanical watches are available for the visually impaired. Here the user has to feel the needles of hour and minute hand to know the time. On the other hand, the touch sensitive watch developed has no moving parts. Thus, there is no scope of breakage in the touch sensitive watch.
