Abstract: An electronic device capable of defining touch gesture is provided. The electronic device includes a touch panel, a touch detection circuit, a processing unit, and a storage unit. The touch detection circuit produces touch signals in response to user touch operation on the touch panel. The processing unit includes a gesture recognition module and a defining module. The gesture recognition module receives the touch signals from the touch detection circuit, and recognizes touch gesture according to the touch signals. The defining module controls the electronic device to enter a defining module in response to user operation, and prompts the user to define a touch gesture for a function of the electronic device, and establish a map between the touch gesture input by the user and the function selected by the user, and store the map in the storage unit.
