1. A haptic input device comprising:
- display means for displaying a cursor and a plurality of buttons;
input means having an operating unit, an operating amount-detecting unit for detecting an operating amount of the operating unit, and an actuator for applying a required feedback force to the operating unit; and
control means for controlling the display of the cursor based on the operating amount signals from the operating amount-detecting unit and for controlling driving of the actuator so as to apply a given attractive force exerted toward one of the buttons to the operating unit based on the positional relationship between the cursor and the buttons,wherein when the cursor moves from a first attractive area that attracts the cursor to a first button displayed on the display means to a second attractive area that attracts the cursor to a second button displayed on the display means, the control means increase the attractive force exerted toward the second button to be larger than a given attractive force by extending the second attractive area during a set increment time.

Abstract
On two buttons displayed adjacent to each other on a display means, when a cursor moves from the center position of a first button to the center position of a second button, an attractive force exerted in the direction opposite to the moving direction of the cursor in an attractive area is increased to be larger than a normal attractive force. Therefore the cursor can move to the desired button easily and surely.

4. A haptic input device comprising:
-
storage means for storing an indicating position and a plurality of functional areas; input means having an operating unit, an operating amount-detecting unit for detecting an operating amount of the operating unit, and an actuator for applying a required feedback force to the operating unit; and control means for calculating the indicating position based on the operational amount and for controlling driving of the actuator to apply a given attractive force exerted toward one of the functional areas to operating unit based on the positional relationship between the indicating position and the one of the functional areas, wherein when the indicating position moves from a first attractive area that attracts the indicating position to a first functional area to a second attractive area that attracts the indicating position to a second functional area, the control means increase the attractive force exerted toward the second functional area to be larger than the given attractive force by extending the second attractive area during a set increment time. - View Dependent Claims (5, 6)

7. A haptic input device comprising:
-
display means for displaying a cursor and a plurality of buttons; input means having an operating unit, an operating amount-detect unit for detecting an operating amount of the operating unit, and an actuator for applying a required feedback force to the operating unit; and control means for controlling the display of the cursor based on the operating amount signals from the operating amount-detecting unit and for controlling driving of the actuator so as to apply a given attractive force exerted toward one of the buttons to the operating unit based on the position relationship between the cursor and the buttons, wherein when the cursor moves from a first attractive area that attracts the cursor to a first button displayed on the display means to a second attractive area that attracts the cursor to a second button displayed on the display means, the control means increase the attractive force exerted towards the second button so that a maximum magnitude of the force exerted towards the second button is greater than a maximum magnitude of a force exerted towards the first button.
