TOUCH RECOGNITION METHOD AND DEVICE, SPACE MOUSE AND CONTROL METHOD THEREOF

摘要

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.
