This research is to develop a functional twosome game, named "Speed Touch". Speed ouch neccesitates reasonable function of the frontal lobe of brain, mainly related to fast decision making and quick response to provided subject, and physical exercises as well. Speed Touch could improve players' abilities of instant response, memory, reflexes, and concentration simultaneously. The simplicity of Speed Touch contents make everyone learn how to play at glance, and different level of difficulty compensates the simplicity. In short, Speed ouch could be called "simple and intuitive". These factors of Speed Touch could relieve poor cognition ability of children, help preventing the old from getting dimentia. This research also requires deep study of human brain functions, human factor engineering, and necessary game factors for successful result, including better attention and cognition abilities.
