Abstract: A touch-input device and an electronic device and a cell phone are described and include a touch acquisition module with an input area to execute touch acquisition operations. The input area includes a first area and a second area. A pointing object location module is used to determine the start location of the touch operation according to the data acquired by the touch acquisition module. A process module is used to calculate a first result indicating the coordinate of the pointing object according to the data acquired by the touch acquisition module when the start location of the touch operation is in the first area, and to calculate a second result indicating the movement of the pointing object according to the data acquired by the touch acquisition module when the start location of the touch operation is in the second area.

Abstract: A method and a mobile terminal for processing touch input are provided. The mobile terminal has a rectangular touch screen with long sides and short sides. The mobile terminal having two state: a first state in which only the short sides are parallel with a horizontal surface and a second state in which only the long sides are parallel with the horizontal surface. The method comprises the following steps of: obtaining from the touch screen a gesture in a first direction as input by a touch object on the touch screen when the mobile terminal is in the first state; triggering a first touch command in response to the gesture in the first direction; obtaining from the touch screen a gesture in a second direction as input by the touch object on the touch screen when the mobile terminal is in the second state, the second direction being the same as the first direction; and triggering the first touch command in response to the gesture in the second direction.

Abstract: A portable terminal is provided, which comprises: a master device and a slave device, the master device includes a master detection unit, a master notification unit and a master control unit, and the slave device includes a slave detection unit, a slave notification unit and a slave control unit; the master detection unit and the slave detection unit are used to detect whether the second interface of the slave device is connected to the first interface of the master device, respectively; when the second interface is connected to the first interface, the master notification unit is used to transmit a first notification instruction to the master device, the slave notification unit is used to transmit the first notification instruction to the slave device; and the master control unit and the slave control unit are used to control the first hardware system and the second hardware system to compose a third hardware system, respectively, after the master device and the slave device connect with each other according
