The invention provides a method for realizing left and right mouse button events and multi-objective operations on a touch screen. The method comprises the steps as follows: reference points are generated according to positions of touch points on the touch screen, and the touch screen is divided into two interaction areas according to the reference points; and the left and right mouse button events are responses to touch operations in the two interaction areas. In addition, on the basis of responses to the left mouse button events, the multi-objective operations are realized through multiple point touching or sliding touching. In the process for realizing mouse operations and the multi-objective operations on the touch screen, the operations can be finished through single-hand touching, and long waiting time and large-range moving operations are not included, so that discomfort of hands when users realize the mouse operations specifically on the touch screen is eliminated; besides, left/right hand habitual operation conversion can be realized through adjustment of ray angles for the touch operations, so that the touch experience can be enhanced, and the instinct touch feeling of people can be embodied.
