[0040] 1. At the beginning of an action, the contact between the user and the touch panel always goes through the process of separation -> insufficient contact -> full contact, so the sampling of the first few points of an action is unreliable. The first points are classified as unreliable data, which is determined by those skilled in the art according to the actual situation. For example, the first two points may be sampled as unreliable data.
[0041] 2. When acquiring x and y, obtain them twice and compare them to obtain dx and dy. According to the changes of dx and dy, we can know the influence of the change of resistance or capacitance on the charging time when touching the panel, so as to obtain the user’s relationship with the touch panel. Check whether the contact of the control panel is stable, and then judge whether the contact is good. According to quantitative research, when the absolute value of dx and dy is less than 3, it is considered that the voltage is stable...

The invention discloses an anti-misoperation method, an anti-misoperation device and an anti-misoperation system of a touch screen. The anti-misoperation method comprises the following steps: starting a necessary software platform and a hardware platform in advance, waiting for and obtaining input information of the touch screen, directly reporting reliable data, and judging whether the operation expressed by the reliable data is an uncertain operation after receiving UP information; reporting a certain operation, and judging whether the operation expressed by the operation at that time conflicts with the actual operation purpose of a user comprehensively expressed by auxiliary information and the reliable data according to the reliable data of the uncertain operation and the auxiliary information; and directly reporting when the operation is the same with the actual operation purpose of the user, and constructing and reporting the actual operation purpose of the user when the operation conflicts with the actual operation purpose of the user. The anti-misoperation device comprises a pre-starting module, an information obtaining module, a first execution module, a second execution module and a third execution module. The anti-misoperation system comprises a hardware collection layer, a driving layer, a framework layer and an application layer. The anti-misoperation method, the anti-misoperation device and the anti-misoperation system of the touch screen can prevent wrong judgment on the operation of the user from occurring to some extent.
Description
technical field [0001] The invention relates to the technical field of touch screen operation, in particular to a method, device and system for preventing misoperation of a touch screen. Background technique [0002] Touch screen (Touch panel), also known as touch panel, is an inductive liquid crystal display device that can receive input signals such as contacts. When touching the graphic buttons on the screen, the tactile feedback system on the screen can The program drives various connection devices, which can be used to replace the mechanical button panel, and create vivid audio-visual effects through the liquid crystal display screen. In the scheme of obtaining user operation information on the touch screen, in order to obtain a faster user response, after the hardware collects reliable data, it should be reported to the upper application as soon as possible. These data can be used in human-computer interaction, click the icon, slide the interface, and enlarge the pictu...
