Detecting touch input and generating perceptible touch stimulus
First Claim
Patent Images
1. An apparatus comprising:
- a body portion having a surface;
at least one feedback electrode configured to provide a time varying feedback stimulus to a digit of a user that is traced across the feedback electrode;
and a touch sensor arrangement for discriminating different user contacts on the surface;
wherein the time varying feedback stimulus is provided by an applied time varying potential difference by modulating a frictional force applied to the digit of the user when the digit, contacting the surface, is traced across the surface.
