Problems solved by technology

[0003] In addition, because the passive stylus does not have a battery, a signal transmission circuit or a button, it cannot further generate more signals for selecting different functions, and it is more inconvenient to use when cooperating with the current multi-functional application program. needs further improvement

Embodiment Construction

[0040] The present invention is aimed at controlling the displacement of an object on the third axis on a touch device as a function switch (like the button being turned on or off). Please refer to Figure 1A As shown, the touch device 40 includes a touch unit 41 and a scanning unit 42, wherein the scanning unit 42 is electrically connected to the touch unit 41, and is connected to several first axes and second axes of the touch unit 41. The axial trace L is connected to scan the touch unit 41 to obtain its sensing information. The scanning unit 42 has a built-in function switching control method, which mainly judges whether there is a preset object on the touch unit 41, and after judging that the preset object exists, according to the change of the sensing information of the preset object , to determine whether a function switching condition is met, once the function switching condition is met, a function switching signal (Switch On) is correspondingly generated, and sent to a...

Abstract

A method for controlling function switch of a touch device has steps of reading sensing information on a touch device when an object approaches or contacts the touch device, determining if the sensing information meets a function-switching condition, and if positive, switching the touch device from the first function mode to the second function mode. When executing an application and receiving a switch-on signal from the touch device, a host computer connected to the touch device activates a function to be switched, for example, an eraser function, a webpage button clicking function, a browser zoom function upon drawing in a drawing application.

Description

technical field [0001] The present invention relates to a touch device and a control method thereof, in particular to a touch device capable of judging function switching and a function switching control method thereof. Background technique [0002] At present, mobile devices such as smart phones and tablet computers all use touch panels as operation interfaces, and users use their fingers as input tools. Although intuitive and convenient to operate with fingers, it may not be suitable for all usage occasions. Taking writing as an example, sliding your finger on the touch panel may not be suitable for large-scale or fast input due to too much friction. When clicking an application, it is also possible that other applications or functional items are touched by mistake because the contact area of ​​the finger is too large. In order to solve the above problems, a stylus has been developed. The existing stylus can be divided into active and passive. The active capacitive stylu...
