USER IDENTIFICATION ON A PER TOUCH BASIS ON TOUCH SENSITIVE DEVICES

摘要

Techniques for communicating particular information from a user to a touch screen device by way of a touch event is provided. Sensors that are operatively coupled to a sensing device sense an input from the user which conveys particular information. This input is then converted by the sensing device into another signal called the sensing device signal which is then transmitted from the sensing device to the user's skin. Then a second set of sensors that are operatively coupled to a touch device receive a user-touch signal that is transmitted from the user's body. The user-touch signal is based, at least in part on the sensing device signal. The touch device then decodes the user-touch signal to determine the location of the touch event on the touch device and sensing device signal embedded in the user-touch signal to extract the particular information related to the user.

主权项

1. A method comprising:
receiving, by a plurality of touch-device sensors operatively coupled to a touch surface on a touch device, a first user-touch signal transmitted from a first user's body while a first device-to-user signal is being applied to the first user's skin; wherein the first user-touch signal is based, at least in part on the first device-to-user signal that conveys first particular information; wherein each touch-device sensor of the plurality of touch-device sensors is located, on the touch surface, at a distinct combination of x, y coordinate values; wherein a sensor controller is operatively coupled to the plurality of touch-device sensors; determining, by the sensor controller, that a first touch event occurred at a first location on the touch device; wherein determining that the first touch event occurred includes determining x, y coordinate values of the first location of the first touch event; based on the first user-touch signal received, the sensor controller determining the first particular information; based on both the first location and the first particular information, determining a particular operation to perform in response to the first touch event; and performing the particular operation.
