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

Embodiment Construction

[0036] Next, preferred embodiments of the programmable display and its screen operation processing program according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to this embodiment.

[0037] figure 1 It is a figure which shows an example of the object used for a programmable display. Objects used in touch-panel-type programmable displays include display objects that only display information, and operation objects that respond to operations such as touch switches.

[0038] As display objects, there are the following display objects, etc.: lamp 501, which switches the display according to the device value of the externally connected device; trend graph 502, which periodically collects device values, and displays the accumulated time-series information in a line graph ; and a numerical value display 503, which directly displays the device value as a numerical value.

[0039] In addition, as oper...

Abstract

A programmable display device is provided with a display unit (101), a coordinate input unit (102), a display processing unit (107), an operation processing unit (108), a control unit (110), and a switching unit that switches so as to enable or disable operation using screen gestures. A display screen comprises a screen gesture application area in which it is possible to change display content and a screen gesture non-application area in which it is not possible to change display content. The switching unit enables operation of operation objects in the screen gesture application area and the screen gesture non-application area when operation by screen gestures is disabled, and disables operation of operation objects in the screen gesture application area and enables screen gestures when operation by screen gestures is enabled. The display processing unit (107) performs predetermined display in the screen gesture application area when operation by screen gestures is enabled.

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...
