The present invention relates to an electric device, which comprises: a micro inertial sensing module, for detecting a motion of the electric device with respect to the degree of freedom of six axes and thus issuing a sensing signal basing on the detection; a sensing signal processor, for receiving and processing the sensing signal to form a system processing signal; and a display; wherein the displacements and rotations of the motion detection-enabled electric device is sensed and measured by the micro inertial sensing module for enabling the micro inertial sensing module to generate sensing signals corresponding thereto and thus sending the same to the sensing signal processor for processing, and then the result of the processing is adopted as the input of the motion detection-enabled electric device for causing the motion detection-enabled electric device to response in the display accordingly. Thereby, the functions of the buttons used as inputting interface of conventional portable game devices can be replaced and thus the fatigue and pain of players' fingers caused by the pressing of buttons can be eliminated, moreover, the displaying area of the display can be enlarged since the area reserved for accommodating conventional buttons is voided.

Electric device with motion detection ability

A motion recognition system and method for controlling electronic devices are disclosed, in which at least a micro inertial sensor, each being arranged at a specific location of a human body, is used to detect and measure a motion of the body so as to correspondently obtain a plurality of gesture parameters, such as angular velocity and acceleration, etc., and then the detected parameters are analyzed and converted into an input gesture sequence by a specific algorithm to be compared with a predefined motion information sequence so as to enable any of the controlled electronic devices to perform a specific operation according to the result of the comparison. In addition, a momentum can be obtained by performing a calculation upon the detected gestured parameters with respect to time, which can be used for controlling the interaction of the controlled electric devices.
