Title:
OPERATION RECOGNITION APPARATUS, OPERATION RECOGNITION METHOD, AND SMART TERMINAL HAVING THE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/109750
Kind Code:
A1
Abstract:
An operation recognition apparatus, an operation recognition method, and a smart terminal having the apparatus. The operation recognition apparatus comprises: an operation receiving unit (11), a scanning array (10) composed of at least one drive channel (101) and at least one sampling channel (102), and at least one signal reading unit (12), wherein the drive channel (101) and the sampling channel (102) intersect to form at least one electrical node (103), and the signal reading unit (12) is connected to the sampling channel (102) and acquires electrical signals on all of the sampling channels (102); and at least one signal source (13), wherein the signal source (13) is connected to each drive channel (101) and sends an electrical signal to all of the drive channels (101), with electrical signals of at least two drive channels (101) thereof being of different frequencies. The signal reading unit (12) comprises at least one band-pass filter (121) to acquire the electrical signal of each sampling channel (102). The method effectively reduces the time delay of operation recognition, and improves the operation recognition efficiency. The method is applicable to an input device of a scanning array type, and particularly to application in the field of touch screens and touchpads.
