Embodiment Construction

[0021] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0022] see Figure 1A , Figure 1B , Figure 1C As shown, it is a schematic diagram of the method for determining the generation of the second contact point according to the historical coordinates of the present invention, wherein the historical coordinates refer to the position of the contact point retained on the touch panel, and the historical coordinates are used to determine the generation of the second contact point On the resistive panel, the operation principle is as follows:

[0023] in Figure 1A is the position of the first contact point of the touch panel, if the position of the first contact point P1 (X1, Y1) remains in the touch state, then the variation of the voltage sensing value (X, Y coordinates) is within a critical value , which forms the historical coordinates.

[0024] in Figure...

Abstract

The invention relates to a control method of multi-point contact control controller applied to an electric resistance type contact control panel, the electric resistance type contact control panel is provided, a contact order of a first contact body and a second contact body can be determined according to contact times of the first contact body and the at least one second contact body respectively contacted with the electric resistance type contact control panel, one first contact coordinate and at least one actual coordinate can be determined in order based on the voltage value sensed by the electric resistance type contact control panel, and the contact body continuously keeps contact with the electric resistance type contact control panel; at least one control instruction can be determined according to the moving track of the actual coordinate.

Description

technical field [0001] The present invention relates to a control method of a multi-point touch controller. Through the coordinate data output by the resistive touch panel, the control method of the present invention can achieve the purpose of judging the multi-point input gesture language, which improves the traditional resistance The shortcoming that the type touch panel can only output single-point coordinate data increases its application range. Background technique [0002] Touch panels originated in the 1970s and were developed by the U.S. military for military use. In the 1980s, the technology was transferred to civilian use, and then developed into various uses. Traditional electronic computing devices (such as computers) use peripheral devices such as keyboards or mice as input interfaces. However, these peripheral input devices are too large and difficult to carry, which is likely to cause a major obstacle to the thinning of electronic products. Due to the demand ...
