Abstract: An exercise machine using motion sensor to track exercise, comprising: an exercise equipment, including a mainframe, the mainframe is fixed and won't be moved by user's movement, an operating mechanism, the operating mechanism is arranged on the mainframe and it will follow the movement of the user; wherein the operating mechanism having a motion sensor, inside the motion sensor having a multiple-axis tracking sensor module and a first microprocessor for detecting the height displacement of the operating mechanism and transmitting the height displacement signal to an electronic control device, then processing by a second microprocessor arranged inside the electronic control device to know whether the motion track of the user reach the preset position during exercise to ensure the effect of exercising.

Abstract: A multifunctional balance exercise machine comprises a balancing mechanism including loading board, spring, elastic column, and motion-tracking sensor; a first display unit and an electronic control device loaded with motion sensor game program arranged on the exercise equipment; whereby when the fitness user stands on the loading board, the user body weight and the stress applied by feet transmit to the elastic column and the spring via the loading board, cause the elastic column and the spring compressed or stretched, and force the loading board to oscillate, then achieve the effect of balance exercise; furthermore, the motion tracking sensor transmit signal of oscillation data to electronic control device, the processor unit operates the data, and present the image of the motion sensor game via the first display unit to achieve entertaining effect of virtual reality game.
