There are many differences between human left brain and right brain. For right-handed people, their left brains are related to language control and logic analysis while their right brains are associated with vision and sense of direction. Diverse things are good for brain, but brain is tired of repeated actions and messages. Therefore, giving different types of training to the brain makes the aerobic training of the brain more interesting. The simple method is to use non-dominant hand to deal with daily routines. This study uses a self-designed mirror game to train human brain. The brain training game is played through the connection between Kinect and a computer. When playing, we try to pass the stages and achieve the purpose of left and right brain balanced training.
