Problems solved by technology

[0004] 1. The current TV remote controls are all the same in appearance and input operation, and the products of major TV production companies cannot highlight their own characteristics
[0005] 2. With the diversification of TV functions, the design of the remote control is becoming more and more complicated, and the sharp increase of buttons makes the remote control operation of the TV more and more inconvenient
[0007] 4. The current gesture remote control is only satisfied with simple operations such as changing the channel and adjusting the volume, and cannot satisfy the precise fingertip mouse control function

Embodiment Construction

[0033] The implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.

[0034] figure 1 Gesture schematic diagram of fingertip mouse interaction method, in which is an image model of a fist with an upright index finger. S1 refers to the fist area. The fist is detected by the template matching method, and then the coordinate value of the rectangular box around the fist is recorded. S2 refers to the index finger area above the fist. The index finger detection in the S2 area is based on the fist image in S1 and the index finger skin color distribution achieved in unison. The two rectangles surrounded by dotted lines in the figure are the areas for subsequent image processing after the fist detection is completed.

[0035] figure 2 The image processing unit includes three processes: fist detection, offline training of fist ei...

Abstract

The invention discloses a television control-oriented finger-mouse interaction method. A television interaction system is characterized by comprising the following steps of: acquiring an image by using a built-in camera of a television; performing image detection on the acquired image to obtain a gesture area; and locating a finger and obtaining a motion coordinate of the finger by using a characteristic of the gesture area, so that an execution device in the television completes the corresponding movement and click operation of a mouse pointer according to the coordinate motion trajectory and residence time of the finger. By the method, the remote control operation of the television can be performed through gesture movement, so a man-machine interaction manner of the television is more intelligent and natural. The long-distance natural remote control manner has remarkable promotion effect on the field of television application under a trend of tri-networks integration.

Description

technical field [0001] The invention relates to a TV remote control technology, in particular to a fingertip mouse interaction method and system for TV control. Background technique [0002] In recent years, with the integration of three networks and the development trend of intelligent TV, TV has rapidly become the intelligent information terminal of the family. This puts forward new requirements for the human-computer interaction technology of TV. TV has the functions of surfing the Internet and information processing. Human-computer interaction on TV requires text input and mouse click functions. The traditional push-button remote controller using infrared rays cannot meet the new interaction requirements brought about by the development of TV. A more intelligent and natural way of human-computer interaction is the urgent need of TV, and the research of TV human-computer interaction has become a research hotspot. [0003] Problems existing in the prior art: [0004] ...
