Programmable display and its screen operation processing program

Abstract

It has: a display unit (101); a coordinate input unit (102); a display processing unit (107); an operation processing unit (108); a control unit (110); / Invalidation is switched, and the display screen has: a screen gesture application area, in which the display content can be changed; and a screen gesture non-application area, in which the screen gesture non-application area cannot display content In the change, when the operation by the screen gesture is invalid, the switching unit enables the operation on the operation target of the screen gesture application area and the screen gesture non-application area, and when the operation by the screen gesture is valid, enables the operation for the operation target of the screen gesture application area and the screen gesture non-application area. The operation of the operation target in the screen gesture application area is invalidated, the screen gesture is enabled, and the display processing unit (107) performs a predetermined display in the screen gesture application area when the operation by the screen gesture is valid.

Description

technical field [0001] The invention relates to a programmable display and its screen operation processing program. Background technique [0002] Computer devices equipped with a display device and a coordinate input unit capable of detecting touch operation coordinates of one or more points, including tablet computers, smartphones, or programmable displays for industrial display and operation terminals, are becoming popular. . In such computer devices, the display contents are becoming finer along with higher functionality and higher resolution of the screen. On the other hand, if a large amount of information is displayed (arranged) on a screen of a limited size, the size of each element (object) becomes small, and visibility and operability deteriorate. In particular, in touch operations, it is difficult to accurately indicate coordinates for an object whose size is not sufficient for the size of a human fingertip, and erroneous operations are likely to occur. Here, an...

Problems solved by technology

However, it is not preferable to activate a function assigned to a switch (for example, a function to switch screens) while touching it.

This is because the point 1 was accidentally performed in the area of ​​the switch at the moment of touch without knowing whether it was a switch operation, a drag or flick operation, or an operation intended to pinch to zoom in or pinch to zoom out. In the state where the touch is distinguished, the switch works, which may cause unexpected actions for the user
