The invention relates to an interaction object control method and belongs to the technical field of man-machine interaction. The method comprises the steps that the quantity of logical pixels, corresponding to a touch control operation, aiming at an interaction object, executed in a touch screen of a terminal is acquired; the density of the logical pixels of the touch screen is acquired; according to the density of the logical pixels and the density of reference pixels, the quantity of the logical pixels corresponding to the touch control operation is corrected; according to the corrected quantity of the logical pixels, the interaction object is controlled. According to the interaction object control method, after the quantity of logical pixels corresponding to the touch control operation aiming at the interaction object is acquired, according to the density of the logical pixels and the density of the reference pixels of the touch screen, the quantity of the logical pixels corresponding to the touch control operation is corrected, and according to the corrected quantity of the logical pixels, the interaction object is controlled, so that when a sliding control operation with the same physical distance is conducted in the random touch screen, the control effects on the interaction object is kept uniform finally.
