Problems solved by technology

However, the current 3D gesture sensing technology needs to install additional wires or other light-emitting elements on the touch screen to complete the 3D gesture sensing, which increases the manufacturing cost and complexity of the touch screen.
In addition, compared with the two-dimensional touch sensing technology, the sensing accuracy of the three-dimensional gesture sensing technology needs to be enhanced

Abstract

The invention provides a three-dimensional gesture sensing method and a touch sensing apparatus using the same. The three-dimensional gesture sensing method comprises the following steps of A: switching at least one first lead wire in a plurality of lead wires of the touch sensing apparatus to a first working lead wire, and switching at least one second lead wire in the lead wires to a second working lead wire, thereby enabling the first working lead wires and the second working lead wires to form sensing regions; B: detecting conductors according to the sensing regions; and C: dynamically adjusting at least one of the sizes, positions and quantity of the sensing regions according to the conductors, thereby finishing three-dimensional gesture sensing. According to the three-dimensional gesture sensing method and the touch sensing apparatus using the same, the at least one of the sizes, positions and quantity of the sensing regions used for detecting the conductors can be dynamically adjusted to realize the three-dimensional gesture sensing method. Compared with a conventional three-dimensional gesture sensing technology, wider sensing range and higher sensing accuracy can be provided.

Description

technical field [0001] The present invention relates to a three-dimensional gesture sensing method, in particular to a three-dimensional gesture sensing method capable of dynamically adjusting a sensing area, and a touch sensing device using the same. Background technique [0002] In recent years, with the diversified development of touch sensing technologies, more and more electronic devices have touch sensing functions. The user can operate the electronic device by touching or pressing the touch screen of the electronic device. [0003] The touch screen includes a resistive overlay touch screen, a photosensitive touch screen, or a capacitive touch screen. The operation principle of the capacitive touch screen is as follows. When the user's finger or object touches the touch screen, by detecting the capacitance value change between the conductive sensing pattern, adjacent sensing patterns, ground electrodes or other components, Instead, the contact position is converted i...
