Identification Method Of Floating Control Object

Abstract

The present invention relates to an identification method of a floating control object. The method comprises the steps of firstly setting a first preset induction amount, wherein a first preset capacitive sensing amount is less than a touch object induction amount; reading the induction amounts of the induction lines on a touch control board, and determining whether the induction amounts of the induction lines exceed the first preset induction amount, if the induction amount of any one induction line exceeds the first preset induction amount, determining that an object exists, identifying the object as the floating control object and then entering a floating control mode. Therefore, an electronic device of the touch control board can be used to detect the approach of the object without using an optical inductor, the touch control board is directly utilized to determine the floating control object which approaches but does not contact, thereby being used as the application of a mobile phone operation system suspended event.

Description

technical field [0001] The invention relates to a method for identifying a touch object, in particular to a method for identifying a floating object. Background technique [0002] At present, the main operation method of the touch screen used in touch-sensitive electronic devices, such as smart phones and notebook computers, is still intuitive touch control. Relatively, because the touch screen combines or integrates a touch panel on a screen, some functions are relatively limited. Such as Figure 6A As shown, taking the phone function of the smart phone 50 as an example, when the user opens the communication software of the smart phone by touching, virtual function buttons 511 such as number buttons, call, and call end will be displayed on the touch screen 51 . Another example Figure 6B As shown, after dialing a call or answering an incoming call, the mobile phone will be placed close to the ear 60, and the ear 60 will be sensed by the touch screen 51 when the ear 60 tou...

Problems solved by technology

[0004] As mentioned above, because the touch-sensitive electronic device uses a touch screen, some functions are restricted or interfered by the touch function, and the above-mentioned smart phone or a touch-control device with a call function is not suitable for short-distance The sensing method additionally uses an optical proximity sensor. Although it can solve the function of false touch during calls, it is not the best solution for the light and thin design of current smartphones.

[0005] In addition, for example, the browsing function is also limited by the size of the touch screen. For example, if a small-sized touch-sensitive electronic device is displayed on a full page after the browser opens the web page data, the text and picture display area will be smaller than the finger touch range, resulting in a one-time Touching multiple virtual function buttons can easily lead to false touches, and the problem of false touches is also caused by the limitation of touch control, and further solutions are yet to be proposed
