Prototype 2 is focused towards testing out feedback methods we can use to communicate with visually impaired persons. A few days ago while going back home I noticed something about human behavior, Whenever someone taps on our shoulder we tend to look in the direction of tap.

\n

Concept

\n

Design a tool/device that replicates a tap action on shoulder of the person wearing it. and guide the person to a direction. Whenever the person needs to turn left it replicates a tap on the shoulder and person moves in that direction. Similarly, for right direction, when a person needs to stop both left and right taps are triggered simultaneously indicating stop.\nIf the destination is on the right, a rhythmic right tap is triggered to indicate the destination is on right.

Implementation

\n

I intend to implement this using servo motors, held on inside of a jacket, both left and right shoulders and it’s hand movement creates a sense of being tapped on the shoulder.

\n

Following demo shows how a servo motor can be used to mimic tap.
