Image information display apparatus
First Claim
1. An image information display apparatus comprising:
- a display unit for displaying image data;
an input unit for performing scrolling of the image data displayed on the display unit; and
a control unit for controlling the display unit and the input unit, wherein the input unit has a manipulation unit manipulated by an operator, a position sensor for detecting a manipulation state of the manipulation unit, and an actuator for supplying force-feedback to the manipulation unit, wherein the image data includes a prescribed point, wherein the control unit calculates an amount and direction of manipulation of the manipulation unit on the basis of positional signals output from the position sensor, and performs the scrolling of the image data on the basis of the amount and direction of manipulation of the manipulation unit obtained, and wherein in the course of scrolling the image data, the control unit calculates the deviation between a direction from a reference point in the display unit to the prescribed point in the image data and the direction of manipulation of the manipulation unit, and controls drive of the actuator to decrease the force-feedback to be supplied to the manipulation unit with a decrease in the calculated deviation.

Abstract
An image information display apparatus is provided, which is inexpensive and is capable of easily performing scrolling of image data from a current position to a destination. The image information display apparatus includes a map data storage unit 1, a display unit 2, an input unit 3, a control unit 4, and a communication satellite 5. The input unit includes a manipulation unit 22 manipulated by an operator, position sensors 25, 26 for detecting a manipulation states of the manipulation unit 22, actuators 23, 24 for supplying a force-feedback to the manipulation unit 22, and destination setting switches 27, 28. The control unit 4 calculates an amount and direction of manipulation of the manipulation unit 22 on the basis of positional signals a, b, and performs scrolling of image data 51 on the basis of the calculated amount and direction of manipulation of the manipulation unit 22 obtained. In addition, the control unit calculates the deviation between the direction of a destination B as seen from a reference point A in the road map data 51 and the direction of manipulation of the manipulation unit 22, and controls drive of the actuator 23, 24 to decrease the force-feedback to be supplied to the manipulation unit 22 with a decrease in the calculated deviation.
