Claim:
1. A operation input device, comprising: a display displaying a plurality of objects and having an operation surface such that a user can place his or her finger on the operation surface and move it along the operation surface with a varying amount of pressure; a pressure sensor for generating a pressure signal indicative of the instantaneous pressure applied to the operation surface by the user's finger such that the value of the pressure signal at any given instant is indicative of the pressure applied to the operation surface at a corresponding instant; a location sensor for generating a location signal indicative of the instantaneous location on the display where the user's finger applies pressure to the operation surface; and a controller which compares the instantaneous value of the pressure signal to a threshold value which decreases over time and, when the instantaneous value of the pressure signal exceeds the threshold, causes a drag operation to be performed on a particular one of the objects corresponding to the location on the operation surface where the pressure applied by the user exceeded the threshold value, the drag operation moving the particular object to a different positional location on the display.
