Abstract: A mobile wireless console which senses three dimensional motion in a mobile terminal to wirelessly transmit a sensing signal of the three dimensional motion to an electronic device such as a computer. In the console, an inputter allows communication mode and motion mode to be inputted. A controller controls execution of the communication mode inputted through the inputter and execution of the motion mode inputted through the inputter. A motion sensing part senses a three axis straight motion and a three axis rotary motion in response to the execution of the motion mode controlled by the controller. A wireless transmitter wirelessly transmits a sensing signal from the motion sensing part. A displayer displays data in response to control of the controller. Also, a wireless communicator communicates in response to the execution of the communication mode controlled by the controller.

Abstract: A mobile terminal with a horizontality display function is provided. In the mobile terminal, a body plane is formed at one side of an exterior of a body of the mobile terminal, and an acceleration sensor is installed parallel to the body plane and detects an acceleration corresponding to a physical change with reference to a reference XY horizontal plane. A memory stores preset sensor offset value and sensor sensitivity value of the acceleration sensor, and a controller calculates inclination angles at which the body plane is inclined with respect to the reference XY horizontal plane, using the sensor offset value and the sensor sensitivity value stored in the memory. A horizontality display unit displays as an image a current horizontality detected by the controller on the basis of the calculated inclination angles with respect to the reference XY horizontal plane.
