Touch panel device
First Claim
1. A touch panel device for an electronic device, comprising:
- a touch panel screen including a plurality of display areas and a plurality of touch areas such that each display area is associated with each touch area, each display area displaying information;
a pressure detector for detecting a pressure applied to each of the touch areas to generate a detection signal representing the pressure;
a signal generator for generating an operation command based on the detection signal; and
a relative relation adjuster for adjusting a relative relation between at least one display area and the associated touch area in terms of at least one of positional relationship and size relationship between the display area and the associated touch area in accordance with a predetermined condition.

Abstract
A touch panel device includes a screen that has a plurality of display areas in a first layer, and a plurality of touch areas in a second layer. The second layer lies over the first layer. One touch area is superposed over one display area. The touch area is generally larger than the display area. A position of each touch area is slightly offset from the corresponding display area, depending upon a relative positional relationship between the touch panel device and a user of the touch panel device. The offsetting may be determined based on ergonomics in order to effectively. prevent an erroneous operation of a user to the touch panel device. The user is a vehicle driver if the touch panel device is used in a car navigation machine.
