Background
In the past, a trackball was used as an indicator operation detection device for performing an operation instruction for moving or rotating an object displayed on a display screen of a personal computer (hereinafter, simply referred to as a computer) in the lateral direction or the longitudinal direction of the display screen. However, since the trackball moves the cursor or the object by an amount corresponding to the amount by which the rotary encoder rotates in accordance with the rotation of the ball, only a relative movement amount can be specified by the movement operation, and it is difficult to instruct the cursor or the object at an accurate coordinate position. In recent years, there has been an increasing chance that a touch panel using a position detection sensor is used as a pointing input device. In particular, a capacitance type sensor is superior to a conventional resistance film type sensor in that it has a high response speed and excellent durability and can simultaneously detect a plurality of indicators such as fingers, and is therefore used in portable electronic devices such as mobile phone terminals.
Since the operation surface portion of the sensor is a convex curved surface, the contact area between the operation surface having the convex shape and the pointing body such as a finger is likely to be reduced, and it is difficult for the sensor to accurately and reliably detect the linear direction pointing operation.
