Intelligent television and gesture control method thereof

Abstract

The invention discloses a gesture control method of an intelligent television. The method includes a first step of capturing an image of a hand through a complementary metal-oxide-semiconductor transistor (CMOS) image sensor, a second step of judging whether fingers of the hand continue to stay at fixed points and whether stay time of the fingers reaches a reset value, a third step of capturing motion changes of the fingers if the time that the fingers continue to stay at the fixed points reaches the reset value, a fourth step of identifying whether the motion changes of the fingers accord with a specific gesture, wherein the specific gesture is a gesture according with a specific motion locus generated by the specific fingers, and a fifth step of carrying out corresponding functions on an operation interface of a display screen when the motion changes of the fingers accord with the specific gesture. The invention further provides the intelligent television with a gesture control function. The intelligent television and the gesture control method thereof effectively improve accuracy of gesture control in man-machine interaction, and enhance affinity of the man-machine interaction.

Description

technical field [0001] The invention relates to gesture control technology, in particular to a smart TV and a gesture control method thereof. Background technique [0002] Smart TV refers to a fully open platform, equipped with an operating system, users can install and uninstall software, games and other programs provided by third-party service providers. Through such programs, the functions of color TVs are continuously expanded, and through A general term for such a type of color TV that uses network cables and wireless networks to realize surfing the Internet. [0003] At present, the arrival of smart TV conforms to the trend of high-definition, network and intelligent TV. In addition to traditional TV reality screens and display drivers, smart TVs also include high-performance computing processor chips, channel source decoding chips, image and data processing chips, high-speed large-capacity storage media, and high-speed data transmission interfaces. Therefore, smart ...

AI Technical Summary

Problems solved by technology

The traditional human-computer interaction function is mainly realized through the handle sensor, and various commands to the TV are realized by the operator operating or shaking the handle sensor in the hand. However, this method needs the help of external equipment to realize human-computer interaction. For the operator, it increases the operating medium and reduces the affinity of the operating experience

In recent years, another human-computer interaction function based on infrared sensors has also appeared. This method of directly capturing the dynamic signal of the operator through infrared sensors effectively avoids the existence of intermediary media and enhances the affinity of human-computer interaction. However, due to The resolution, accuracy, light source performance and other issues of the infrared sensor make it difficult to achieve the best results in this way of operating experience
