Abstract

A photosensitivity-based gesture identification method, applicable for a digital terminal having a photosenstive structure to identify a user gesture. The method comprises the following steps: the photosensitive structure senses if light is shielded; and if so, then inputting a first control signal to the digital terminal, and if not, then inputting no control signal to the digital terminal. The method enables detecting, by means of the photosensitive structure of the digital terminal, whether the digital terminal is shielded; if the digital terminal is shielded, then a first control signal is inputted to the digital terminal. During use, if inputting of a signal can be performed by means of shielding the photosensitive structure, the need to directly contact the digital terminal can be eliminated, thus minimizing influences on the digital terminal.

Description

 Specification Name of Invention: Light Sensing Gesture Recognition Method Technical Field

 [0001] The present invention relates to the technical field of digital terminals, and in particular, to a light-sensing gesture recognition method.

 Background technique

 [0002] As digital terminals operating with various touch screens have become more and more popular, such as tablet computers, smart phones, etc., the manner of touch operation has become more and more popular. Since the touch operation requires direct contact with the touch screen surface, the touch screen itself has a small area, and the touch process exerts a certain force on the touch screen, which easily affects the use of the digital terminal. For example, the prior art retaining clips typically have a collet that can be clamped to the table, the head of the bed, a bendable connecting tube, and a collet that can grip the digital terminal. Fix the clamp head with the 吋, then bend the adjustment connection tube so that the clamp body is in the proper position in front of the user, and then fix the digital terminal on the clamp body, so that the digital terminal can be viewed without holding the hand for a long time. The clip that ultimately supports the digital terminal is a connecting tube. This structure is elongated and bendable, which causes the digital terminal to swing easily with a small force, especially when the user touches the digital terminal. The digital terminal is easy to shake from side to side, and it needs to be corrected for a period of time to stand still.

 technical problem

 [0003] The object of the present invention is to provide a light-sensing gesture recognition method, which aims to solve the problem that the digital terminal needs contact control in the prior art, which easily affects the use of the digital terminal.

[0005] The photosensitive structure senses whether or not the light is blocked, and if sensed, inputs a first control signal to the digital terminal, and if not sensed, does not input a control signal to the digital terminal.

[0006] Further, the method further includes the following steps:

 [0007] If it is detected that the light is blocked for more than t, a second control signal is input to the digital terminal.

[0008] Further, the front end of the digital terminal is provided with a first photosensitive structure and a second photosensitive structure distributed left and right. The method further includes the following steps: the first photosensitive structure and the second photosensitive structure are sequentially detected to be shielded from light, and then a third control signal is input to the digital terminal; the second photosensitive structure and the third photosensitive structure are sequentially When it is detected that the light is blocked, a fourth control signal is input to the digital terminal.

 [0009] Further, the method further includes the following steps: detecting frequent occlusion and light transmission, and inputting a fifth control signal to the digital terminal.

 [0010] Further, the digital terminal is internally provided with a control program, and when the control program is started, the photosensitive structure detects whether the light is blocked and inputs a control signal to the digital terminal, and the control program is closed, the The photosensitive structure detects the light intensity and inputs light intensity information to the digital terminal.

 Advantageous effects of the invention

 Beneficial effect

 [0011] Compared with the prior art, the light-sensing gesture recognition method in the present invention can detect whether it is occluded by means of the photosensitive structure of the digital terminal itself, and if occluded, input the first control signal to the digital terminal, If you can use the photographic structure to block the signal input to the digital terminal without directly touching the digital terminal, it is not easy to affect the digital terminal.

Embodiments of the invention

 [0008] The present invention will be further described in detail in the following examples in order to make the objects, aspects, and advantages of the invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

 [0013] A light-sensing gesture recognition method for a digital terminal with a photosensitive structure to recognize a user gesture includes the following steps:

 [0014] The photosensitive structure senses whether the light is blocked, if it is sensed, the first control signal is input to the digital terminal, and if it is not sensed, the control signal is not input to the digital terminal.

[0015] For example, in the following occasions:

[0016] The user lies on the bed, clamps the digital terminal through the fixed clip, watches the video, the e-book or listens to the music, and thus needs to operate the digital terminal, such as pausing the video, flipping the e-book, switching the next song, etc. The user only needs to block the photosensitive structure of the digital terminal with a finger, and the photosensitive structure senses that it is blocked, and the first control signal is input into the digital terminal to perform corresponding operations. Because a fairly high proportion of digital terminals are equipped with sensitization The photosensitive structure for automatically adjusting the brightness can be operated by the light-sensing gesture recognition method in the present embodiment. The user can operate without directly touching the digital terminal, and does not cause the digital terminal to shake, even if wearing gloves. It can also be operated, even in the shower, it can also be operated through the waterproof glass, which greatly expands the operation convenience of the digital terminal, so that it can recognize the gesture.

[0017] The light-sensing gesture recognition method further includes the following steps:

 [0018] If it is detected that the light is blocked for more than t, a second control signal is input to the digital terminal.

 [0019] For example, t is 2s, and after the blackout period exceeds two seconds, the second control signal is input to the digital terminal, and can be operated as a second gesture signal, for example, returning to the menu, answering the phone, replying to the message, and tying the device in advance. Functions such as software programs.

 [0020] If the front end of the digital terminal is provided with the first photosensitive structure and the second photosensitive structure distributed left and right, the light sensing gesture recognition method further includes the following steps: the first photosensitive structure and the second photosensitive structure are sequentially detected to be blocked, and then input The third control signal is sent to the digital terminal; the second photosensitive structure and the third photosensitive structure are sequentially detected to be shielded from light, and then the fourth control signal is input to the digital terminal.

 [0021] That is, the first photosensitive structure and the second photosensitive structure are sequentially blocked from left to right and from right to left, and can be recognized as two gesture signals, such as volume addition and subtraction, before and after track switching, upper and lower menu switching, and the like.

 [0022] The light-sensing gesture recognition method further includes the following steps: detecting frequent occlusion and light transmission, inputting a fifth control signal to the digital terminal.

 [0023] The digital terminal is internally provided with a control program. When the control program is started, the light-sensing gesture recognition method function is activated, and the photosensitive structure detects whether the light is blocked and the control signal is input to the digital terminal. After the control program is turned off, the light-sensing gesture recognition method is turned off, and the photosensitive structure detects the light intensity and inputs the light intensity information to the digital end mountain.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, and improvements made within the spirit and scope of the present invention are included in the present invention. Within the scope of protection.
