This is a kinect somatosensory device based on the unity platform design and development of interactive games. This design is mainly designed around the popular science of Wing Chun. The main purpose is to solve the current situation that the physique of young people brought by the house culture is gradually weakening. Through playing and exercising at home, the user's amount of exercise is improved and the user's impression of Wing Chun boxing is deepened, and the spirit of Wing Chun is inherited. This design takes the excellent traditional martial arts Wing Chun, which is known to the public but not understood, as the main content and combined with somatosensory equipment, and develops an interactive game suitable for all ages, simple operation, innovative way and strong sense of interaction. Principle of human-computer interaction simulation somatosensory game: use projector to project Unity scene and Wing Chun boxing action (the scene and action are made by Photoshop and unity and then imported into unity) to wall surface, use Kinect to obtain data of user's skeleton and depth image, and send it to Unity in real time. Unity judges whether user's action is consistent with the action specified in the game according to the data, when the movements are consistent and maintained for a period of time, it will show the clearance to unlock the next Wing Chun movement. At the same time, simplifying certain game processes helps players focus more on the game itself and the culture it contains.
