Problems solved by technology

However, for the existing capacitive touch key system, if the panel material is made of metal material or the panel material contains metal components, any touch on the panel will trigger the key, which makes it impossible to identify which key a certain trigger belongs to. , which will cause touch operation errors and affect the user's use

Embodiment 1

[0048] figure 1 It is a schematic flowchart of the touch recognition method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the touch recognition method includes:

[0049] Step S101, when the voltage corresponding to the total amount of charge transferred on each electrode of the touch key structure reaches the reference voltage, the number of charge transfers of each electrode is used as the charge of the key corresponding to the electrode when the touch key structure is facing a touch or near touch sample value;

[0050] Step S102, obtaining the long-term average value of the charge sample value within the first preset time;

[0051] Step S103, identifying the key whose difference between the long-term average value and the currently obtained charge sample value is greater than or equal to the touch sensing threshold as the touched key.

[0052] Wherein, the touch button structure includes: a touch panel and a detection board, the touch pane...

Embodiment 2

[0100] The difference between this embodiment and the first embodiment lies in that the structure of the touch button, the space mouse and its control method are different. As described in Embodiment 1, after the touched key is recognized by the touch recognition method, a corresponding first control signal is generated according to the recognition result to control the operation of the space mouse, and realize the preset function of the touched key . The space positioning of the space mouse is realized through the data output by the inertial device included in the space mouse, so that the movement of the mouse pointer can be controlled. When the preset function of the touched button is specifically the mouse pointer controlled by the space mouse When the position confirmation function is selected, by delaying the generation of the first control signal and shielding the processing chip in the space mouse from processing the output data of the inertial device within the delayed...

Embodiment 3

[0110] The touch button structure described in Embodiment 1 is a touch button structure without pressure (zero pressure), which can be referred to image 3 , that is, after the user’s finger touches the metal button on the touch panel 201, the touch behavior can be detected more accurately without pressing the metal button hard. The pressure and the deformation of the metal key under the action of the pressure are used to detect the touch behavior. For the specific touch recognition process, please refer to the relevant description in the first embodiment.

[0111] In the touch button structure described in Embodiment 1, since the metal buttons included in the touch panel are separated from the board by an insulating layer, the touched metal buttons can be identified more accurately. However, if the touch panel is made of metal buttons and For an all-metal touch panel with integrated board body, after touching a certain metal key, part of the charge will also be transferred to...

Abstract

A touch recognition method and device, a space mouse and a control method thereof. The touch recognition method includes: taking the number of times of charge transfer of each electrode when the voltage corresponding to the total charge quantity transferred on each electrode of a touch key structure reaches a reference voltage as a charge sample value of a key corresponding to the electrode when the touch key structure is touched or will be touched; obtaining a long-term average value of the charge sample value within a first preset time; recognizing a key in which the difference between the long-term average value and the currently obtained charge sample value is greater than or equal to a touch sensitive threshold value as a touched key, wherein the touch key structure includes: a touch panel and a detection plate isolated from the touch panel in an insulated way, and the touch panel is provided with a plurality of metal keys, and the detection plate is provided thereon with a plurality of electrodes corresponding to the metal keys. The technical solution in the present invention can improve the accuracy of touch recognition, and effectively avoids the jitter of the mouse point when a space mouse presses down a key with a confirm function.

Description

technical field [0001] The invention relates to the technical field of touch sensing, in particular to a touch recognition method and device, a space mouse and a control method thereof. Background technique [0002] Currently, common mouse devices on the market are divided into two types according to their operating principles, one is a roller mouse, and the other is an optical mouse. Among them, the rolling ball mouse is to control the pointing position of the mouse pointer (cursor or cursor) displayed in the computer system by converting the moving direction and path of the rolling ball on the placed desktop or plane; Control the reflection caused by the light on the table or plane. For the positioning of the mouse pointer of an optical mouse, most of them rely on optical sensors or laser sensors. These sensors are all based on the principle of physical optics, so that the sensors need to be realized by platforms such as desktops. In addition, in many occasions, such as ...
