Smart TV with gesture recognition remote control

This creation is about a smart television, and in particular, a smart TV using a gesture recognition remote control.

 

At present, a large number of smart TVs appear on the market, and smart TVs using Android (android) systems have been vigorously promoted and popularized. Smart TV brings intelligent interactive control methods and a better user experience. Facial recognition, gesture control, video chat, voice control, etc. are all essential functions and features in smart TV.

There are many existing gesture control schemes, and the gesture recognition module is generally set in the television host. For example, SoftKinetic has developed a gesture input technology that uses autonomous distance image sensors, which captures reflected light through a camera after illuminating the object, and then calculates the distance from the object based on the time the reflected light arrives. Time of flight (TOF). PrimeSense has developed a light coding technology that uses continuous light (near-infrared) to encode the measurement space. The sensor reads the encoded light and sends it to the wafer for decoding to produce a depth. image. The key to optical coding technology is the laser speckle. When the laser light strikes a rough object or penetrates the frosted glass, it will form a random reflection spot called a speckle. Speckle is highly random. As the distance transforms the pattern, the speckles at any two places in the space are different patterns, and the entire space is marked. Therefore, any object entering the space and moving can be exact. Record the location of the object. In addition, Eyesight has developed a two-dimensional (2D) image to recognize user gestures and further control gestures to the TV host.

In the above existing gesture control scheme, the gesture recognition module is set in the television host, but since the user watches the television, it maintains a certain distance from the television host, and because the image acquisition unit in the gesture recognition module (For example, the camera) is fixed on the TV main unit, so the image acquisition angle cannot be adjusted. At the same time, the image acquisition is also subject to the range of the field of view of the image acquisition unit. Many areas in front of the TV host cannot perform image acquisition, and thus cannot acquire gestures. Therefore, when the user stands in the field of view of the image acquisition unit in front of the TV host, When the range is outside, the gesture control of the smart TV cannot be achieved.

In addition, due to the viewing distance of the user and the angle of view of the image capturing unit, the details of the captured gesture image are affected, which reduces the quality of the gesture image. Therefore, when the gesture image information collected over a long distance is used to intelligently control the television, the gesture recognition rate is low. Furthermore, existing gesture control techniques require a large number of algorithms and require a large amount of processor resources in the television host.

The purpose of this creation is to propose a smart TV using a gesture recognition remote control, which has a high gesture recognition rate and can perform gesture control at a long distance.

In order to achieve the above object, the present invention proposes a smart television using a gesture recognition remote controller, which comprises a remote controller and a television body, wherein the remote controller is provided with a gesture recognition module for collecting user gestures, and a user gesture to be collected. a controller for performing feature extraction and recognition, and a signal transmitter, wherein an input end of the controller is electrically connected to the gesture recognition module, and an output end of the controller is electrically connected to the signal transmitter, the television The body is provided with a signal receiver electrically connected to each other and a processor, and the remote controller is electrically connected to the signal receiver in the body of the television through the signal transmitter therein.

In an embodiment, the signal transmitter in the remote controller is an infrared signal transmitter or a radio frequency signal transmitter, and the signal receiver disposed in the television body corresponds to the signal transmitter.

In an embodiment, the gesture recognition module is provided with a camera for capturing user gesture images.

In an embodiment, the remote controller is further provided with a sensor for sensing the position, movement or acceleration of the user, and the sensor is electrically connected to the other input end of the controller in the remote controller.

The technical means described in one embodiment above can be applied to the other embodiment described above to obtain a new embodiment as long as the technical means are not contradictory.

The smart TV adopting the gesture recognition remote controller of the present invention sets the gesture recognition module in the remote controller, and can collect the user gesture image at close range and at any angle, and the camera in the gesture recognition module can be easily adjusted and controlled, which can not only improve Gesture recognition rate can also give users a new interactive experience, regardless of the distance and angle of the user from the TV body. In addition, the gesture command collected by the gesture recognition module in the remote controller can be sent to the television body through a wireless manner such as an infrared signal transmitter or a radio frequency signal transmitter, and can be transmitted within the range of wireless coverage. Therefore, the smart TV using the gesture recognition remote controller of the present invention avoids the problem that the gesture recognition rate caused by the degradation of the gesture image quality that cannot be adjusted and collected in the television host is currently low.
