Hand training method with force feedback and hand training device

A force feedback hand training method, comprising:

• providing a training game content and adjusting the training game content based on predetermined parameters;
• displaying the training game content on a display;
• determining whether an input button position of at least one input signal from a hand training device matches a predetermined input button position;
• and
• storing a determination result in a storage module, wherein:
• the hand training device, comprising:
• a bottom surface;
• a top surface connecting to the bottom surface;
• a plurality of buttons, wherein the plurality of buttons are configured on one side of a connecting portion of the top surface and the bottom surface, and are spaced apart from each other, wherein a moving direction of the button is parallel to the bottom surface;
• a plurality of pressure sensors, wherein each pressure sensor respectively corresponds to the button;
• a signal transmitter configured to transmit signals generated by the pressure sensors;
• a fixing portion having a ring structure with a hole, wherein the fixing portion is configured on a side of the button opposite to the pressure sensor;
• an angle sensor, wherein the angle sensor is configured on a side of the button same to the pressure sensor;
• and
• a pivot, wherein the pivot connects the fixing portion and the angle sensor, when the fixing portion moves along a direction parallel to the bottom surface, the pivot rotates along a direction normal to the bottom surface.
