Touch recognition method, device, spatial mouse and control method thereof

Abstract

一种触摸识别方法及装置、空间鼠标及其控制方法,所述触摸识别方法包括:当触摸按键结构面临触摸或临近触摸时,记录从所述触摸按键结构的各电极上转移的电荷总量对应的电压达到参考电压时各电极的电荷转移次数;每隔预定周期采集各电极上转移的电荷总量对应的电压达到参考电压时各电极的电荷转移次数作为所述电极对应的按键在所述触摸按键结构面临触摸或临近触摸时的电荷样本值;将连续的第一预设数量个预定周期内采集的所述电荷样本值均小于触摸感应阈值的按键识别为被触摸按键。本发明技术方案能提高触摸识别的准确度,并有效避免按键的误触发。
Disclosed are a touch recognition method, a device, a spatial mouse and a control method thereof. The touch recognition method includes steps of recording the charge transfer frequencies of various electrodes when a touch button structure is pressed or is about to be pressed and voltage corresponding to total quantities of charge transferred from the electrodes of the touch button structure reaches reference voltage; sampling the charge transfer frequencies of the electrodes when the voltage corresponding to the total quantities of the charge transferred from the electrodes reaches the reference voltage at predetermined intervals, and adopting the charge transfer frequencies as charge sample values of buttons corresponding to the electrodes when the touch button structure is pressed or is about to be pressed; and recognizing a button as a touched button when charge sample values, which are continuously acquired within a first predetermined number of periods, of the button are smaller than a touch sensitive threshold value. By the aid of the technical scheme of the touch recognition method, the device, the spatial mouse and the control method, touch recognition accuracy can be improved, and false triggering of the buttons can be effectively avoided.
