example

[0032] refer to figure 1 and image 3 As shown, a 100*100 touch screen needs to be a graphical interface on it. Among them is an icon located at coordinates (x1, y1), width and height (w, h), and now we want to listen to its click event.

[0033] First, register the click event with the event processing center, x=x1, y=y1, width=w, height=h, at this time the processing center keeps this data in the list.

[0034] When a click event is received from the event processing center, the current finger click coordinates will be given, x=x2, y=y2, and the data will be compared with the held data at this time, if x2>x1&&x2 y1&&y2

[0035] For the above-mentioned custom registration control click event, the interrupt event of the touch screen can be flexibly defined, and the effective touch range of the control can be changed, so that the control can obtain a larger touch area instead of being limited to the icon area, especiall...

Abstract

The invention discloses an embedded equipment touch screen gesture processing method. The method includes the following steps that an interrupt event, monitored by a screen, of the touch screen or a control on the touch screen is registered to an event processing center, and the interrupt event is saved and sent; gesture information in the touch screen is monitored and acquired in real time; the gesture information and the interrupt event sent by the event processing center are compared, and a click event of the control or a rolling event of the touch screen is acquired. Whether any control on the touch screen is clicked or not or the rolling event exists or not can be sensed in real time, the maximum innovation is that the interrupt event of the touch screen can be flexibly defined, the touch effective range of the control can be changed, therefore, the control can acquire a larger touch region and is not limited by an icon region any more, and the control is especially suitable or users with bad eyesight. In addition, some tiny rolling can serve as the click event to be processed.

Description

technical field [0001] The invention relates to the technical field of smart touch screens, in particular to a gesture processing method for a touch screen of an embedded device. Background technique [0002] In a hardware device equipped with a capacitive touch screen, it is necessary to capture the level change of the color screen to generate an interrupt to notify the system of gesture touch events. The color screen only provides the level change of the touch, and can only obtain the coordinates of the current finger, but cannot obtain the touch event of the gesture. The present invention is developed based on this. Contents of the invention [0003] The present invention overcomes the problem that the color screen in the existing capacitive touch screen can only obtain the current finger coordinates but cannot obtain the touch event of the gesture, and proposes a touch screen gesture processing method for an embedded device, which can make the existing capacitive touch...
