Abstract
A method of creating a touch sensitive surface comprising detecting a voltage change in a light sensitive voltage generating device from among an array of light sensitive voltage generating devices that comprise a touch sensitive surface, in response to a lack of energy within a non-visible light spectrum reaching the light sensitive voltage generating device when a user contacts the touch sensitive surface, generating one or more location coordinates corresponding to a location in the array at which the voltage change occurred, and transmitting the one or more location coordinates to a processor configured to process a touch command received by the touch sensitive surface.

A method of creating a touch sensitive surface comprising:
- detecting a voltage change in a light sensitive voltage generating device from among an array of light sensitive voltage generating devices that comprise a touch sensitive surface, in response to a lack of energy within a non-visible light spectrum reaching the light sensitive voltage generating device when a user contacts the touch sensitive surface;
- generating one or more location coordinates corresponding to a location in the array at which the voltage change occurred;
- and
- transmitting the one or more location coordinates to a processor configured to process a touch command received by the touch sensitive surface.
A touch sensitive surface comprising:
- a plurality of touch sensitive voltage varying devices (VVD) configured to form a grid;
- a voltage detector configured to measure a change in a voltage of one or more touch areas on the grid when a user touches the touch sensitive surface;
- and
- a processor configured to calculate an average voltage of each VVD and process a touch command received by the touch sensitive surface in response to a voltage drop in a touch area of the grid that corresponds with a location of the touch area in which the voltage drop occurred.
A touch sensitive surface comprising:
- a plurality of touch sensors configured in an array;
- a voltage detector configured to detect a voltage change at a location in the array that is caused by a user touching the touch sensitive surface;
- a processor configured to:
- calculate one or more location coordinates corresponding to the location in the array in response to the voltage change detected;
- and
- process a touch command corresponding to the location in the array associated with the one or more location coordinates;
- a recharging circuit configured to recharge a battery coupled to the recharging circuit using voltages produced by the touch sensors;
- and
- a unidirectional device configured to prevent backward current flow from adjacent touch sensors resulting from the voltage drop at the location in the array corresponding to the one or more location coordinates.
