METHOD, DEVICE AND TOUCH-CONTROL DETECTION DEVICE FOR FINGER POSITIONING ON TOUCHSCREEN IN WET STATE

Document Type and Number:

WIPO Patent Application WO/2019/014822

Kind Code:

A1

Abstract:

The present invention belongs to the field of touch-control technologies, and discloses a method and device for finger positioning on a touchscreen in a wet state, the method comprising: locating suspected wet areas on a touch screen by means of interval encoding, determining a wet area from the suspected wet areas by means of self-contained encoding (201); traversing full-screen detection channels by self-contained encoding (202); determining whether the detection channels in the wet area satisfy a first condition (203); if the first condition is satisfied, determining, according to a variation in differences of feature data of the detection channels inside the wet area, a relative positional relationship between touch-control positions of fingers and the wet area (204); and if the first condition is not satisfied, determining, according to variations in feature data differences of the detection channels outside the wet area, a relative positional relationship between touch-control positions of fingers and the wet area (205). The method and device can be used to provide a basis for improving normal finger operations in a wet touchscreen state, thus enabling a wet touchscreen to accurately respond to touch control.
