In a wheelchair training platform, a wheelchair is connected to a computer system through the training platform, and the training platform detects signals of a rotary speed and a forward direction or a reverse direction of two rear wheels of the wheelchair, and sends the signals to a computer system. The computer system reflects the foregoing rotary speed and direction to a virtual reality interactive software/game, such that the wheelchair has an interaction with the virtual reality interactive software/game.
