Abstract: A sensing device for measuring movement of linear/arc path, being adapted to adhere to a body, is capable of determining specific movements of the body, which comprises: at least a two-axis accelerometer, for detecting accelerations measured along a first direction and a second direction and thus issuing a sensing signal corresponding to the detection; a signal processor, for processing the sensing signal received thereby and thus providing a data of acceleration; and a means of measurement, capable of determining and measuring a linear/arc movement of the body with respect to the data of acceleration.

Abstract: The present invention relates to a wireless inertial input device of low power consumption. The wireless inertial input device uses an inertial sensing cell, being arranged therein, to generate a sensing signal to be received and processed by a processor for enabling the processor to generate a response signal to be applied by an electric device, whereas the inertial sensing cell is communicating with the processor wirelessly as the processor is not physically connected to the inertial sensing cell and is electrically connected to the electric device. By separating the high power consuming processor from the wireless inertial input device as the sensing signal generated by the inertial sensing cell arranged inside the wireless inertial input device is transmitted wirelessly to the processor to be processed, the power consumption of the wireless inertial input device is reduced and thus the duration of batteries used thereby can be increased.

Abstract: An interactive system with movement sensing capability, comprising: an inertial sensing unit disposed on a movable object so as to sense a movement of the movable object and generate a corresponding signal; a control unit connected to the inertial sensing unit so as to transmit the signal; and a multi-media unit receiving the signal so as to display a corresponding first image and a second image interacted with the first image.
