Haptic input device

A distance vector from the original cursor position (OC) where the cursor exists before the manipulation to the cursor movement destination position (TC) is set to a movement direction distance vector (Vn), distance vectors from the original cursor position (OC) to each button position of a plurality of buttons are set to button distance vectors (Da), and the button having the shortest movement time is determined as a target button (BT) intended by a user by computing the movement time to a plurality of buttons using the movement direction distance vector (Vn) and a plurality of button distance vectors (Da), so that the display control of the display unit is performed such that the cursor is dragged into the target button (BT).
