The invention relates to a touch control method. Two detection units are arranged in a touch screen unit and used for detecting vibration caused by touching a function or program selecting operation area by a user, respectively detecting propagation time for propagating a vibration wave of a vibration point to the two detection units or propagation distances from the vibration wave of the vibration point to the two detection units, and sending detected numerical values to a control unit simultaneously; and the control unit receives the numerical values which are sent by the two detection units, compares the numerical values with standard numerical values which are pre-stored in a storage unit, and finds coordinate information which corresponds to the vibration point, so the specific position and corresponding functions or programs of an operation point of the user are determined, corresponding response is carried out, and setting of the functions or the programs is realized. By the method, the touching mode of vibration detection is completely realized; influence of an electric field on interference of the method is avoided; detection precision is high; and the method is very convenient to use.
