By a News Reporter-Staff News Editor at Journal of Engineering -- PixArt Imaging (Hsin-Chu, TW) has been issued patent number 10013071, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Chen, Yu-Han (Hsin-Chu, TW); Liao, Chi-Chieh (Hsin-Chu, TW); Lee, Chia-Yi (Hsin-Chu, TW).

This patent was filed on November 1, 2016 and was published online on July 3, 2018.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The instant disclosure relates to a three-dimensional gesture sensing method; in particular, to a three-dimensional gesture sensing method that can dynamically adjust sensing areas and a touch sensing device using the same.

"In recent years, with the development of the touch sensing technology, there are more and more electric devices having the touch sensing function. A user can operate an electric device by touching or pressing a touch screen of the electric device.

"The touch screen can be, for example, the resistive overlay touch screen, the photosensitive touch screen, the capacitive touch screen or the like. The working principle of the capacitive touch screen is as follows. When a user uses his finger or an article to contact the touch screen, the touch screen can transform the information of the contact position to an electric signal by detecting the capacitance variations between the conductive sensing patterns, between the adjacent sensing patterns, between the grounding electrodes or between other electric elements.

"Moreover, the three-dimensional gesture sensing technology has been developed recently, by which a user can operate an electric device without directly contacting a touch screen thereof. However, currently, to implement the three-dimensional gesture sensing, there are additional conductive lines or additional light emitting elements needed to be configured in the touch screen, which increases the cost and the complexity regarding manufacturing a touch screen with the three-dimensional gesture sensing function. In addition, compared with the two-dimensional touch sensing technology, there is still room for improvement of the detection accuracy regarding the three-dimensional gesture sensing technology."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "The instant disclosure provides a three-dimensional gesture sensing method. The three-dimensional gesture sensing method is used in a touch sensing device. The three-dimensional gesture sensing method comprises steps as follows. Step A: driving at least one first conductive line of the conductive lines in the touch sensing device as a first working sensing line, and driving at least one second conductive line of the conductive lines in the touch sensing device as a second working sensing line, such that a sensing area is formed between the first working sensing line and the second working sensing line. Step B: detecting a conductor according to the sensing area. Step C: dynamically adjusting at least the area, the position or the amount of the sensing area according to the conductor to implement a three-dimensional gesture sensing.

"The instant disclosure further provides a touch sensing device. The touch sensing device is used to dynamically adjust at least the area, the position or the amount of the sensing area for detecting a conductor. The touch sensing device comprises a capacitive touch panel and a driving circuit. The capacitive touch panel comprises a plurality of conductive lines parallel with each other. The driving circuit is connected to the conductive lines. At a first timing, the driving circuit drives at least one first conductive line of the conductive lines as a first working sensing line and drives at least one second conductive line of the conductive lines as a second working sensing line, such that a sensing area is formed between the first working sensing line and the second working sensing line.

"To sum up, the three-dimensional gesture sensing method and the touch sensing device using the same provided in the embodiments of the instant disclosure can dynamically adjust at least the area, the position or the amount of the sensing area for detecting a conductor, to implement the three-dimensional gesture sensing. Compared with the traditional three-dimensional gesture sensing method, a larger sensing region and remarkable detection accuracy are provided by the three-dimensional gesture sensing method and the touch sensing device using the same provided in the embodiments of the instant disclosure.

"For further understanding of the instant disclosure, reference is made to the following detailed description illustrating the embodiments of the instant disclosure. The description is only for illustrating the instant disclosure, not for limiting the scope of the claim."
