Patent ID: 8289292

Claim:
An electronic device comprising: a first touch panel and a second touch panel both configured to produce touch signals in response to user operations; a first touch controller connected to the first touch panel and configured to determine touch information including a touch position and a touch path when receiving the touch signals from the first touch panel; a second touch controller connected to the second touch panel and configured to determine touch information including a touch position and a touch path when receiving the touch signals from the second touch panel; and a processing unit connected to both the first touch controller and the second touch controller, the processing unit comprising: a receiving module configured to receive touch information from the first touch controller and the second touch controller; a startup module configured to enable the second touch controller when the receiving module receives the touch information from the first touch controller; a mode switching module configured to set the electronic device to single-surface touch mode when the receiving module only receives the touch information from the first touch controller, and set the electronic device to double-surface touch mode when the receiving module receives the touch information both from the first touch controller and the second touch controller; an identifying module configured to determine a gesture according to the touch information from the first touch controller in the single-surface touch mode or determine a combined gesture according to the touch information from the first touch controller and the second touch controller in the double-surface touch mode; and an executing module configured to execute the function associated with the gesture in the single-surface touch mode or the function associated with the combined gesture in the double-surface touch mode.
