TACTILE PRESENTATION OF INFORMATION
First Claim
1. A device for providing information to a user, the device comprising:
- a plurality of individually-addressable cells, each cell including an electrically-active material capable of changing shape and/or position in response to an electrical current;
a electrical network connected to, and capable of delivering the electrical current to, each of the plurality of individually-addressable cells;
a membrane atop the plurality of individually-addressable cells, onto which the change in shape and/or position of the electrically-active material in each cell may be transferred; and
a receiver for receiving information capable of tactile presentation to a user using the plurality of individually-addressable cells.
