Claim Text:
1. A system for transmitting particular information to a touch device comprising: one or more first sensors, operatively coupled to a sensing device, configured to detect input that conveys the particular information; a processing unit operatively coupled to the sensing device configured to convert the input into a device-to-user signal that conveys the particular information; a transmitter, operatively coupled to the sensing device, configured to transmit the device-to-user signal to user's skin to communicate the particular information to a touch device when the user is using the touch device; a plurality of second sensors operatively coupled to a touch surface on the touch device; wherein each sensor of the plurality of second sensors is located, on the touch surface, at a distinct combination of x, y coordinate values, a sensor controller operatively coupled to the plurality of second sensors; wherein each of the plurality of second sensors is configured to report capacitance data to the sensor controller; wherein the sensor controller is configured to determine that a touch event occurred at a particular location on the touch device based on determining that a spike in capacitance, above a threshold level, occurred at a particular sensor, of the plurality of second sensors, whose location corresponds to the particular location; wherein the sensor controller is configured to determine x, y coordinate values of the particular location of the touch event; wherein the touch even causes one or more second sensors of the plurality of second sensors, other than the particular sensor, to receive device-to-user spikes in capacitance that reflect a user-touch signal transmitted from the user's body while the device-to-user signal is being applied to the user's skin, wherein the user-touch signal is based, at least in part, on the device-to-user signal; wherein the device-to-user spikes in capacitance received by the one or more second sensors are below the threshold level; and wherein the sensor controller is configured to determine the particular information from the device-to-user spikes in capacitance received by the one or more second sensors.
