Multichannel man-machine interaction table surface television

Abstract

The invention discloses a multichannel man-machine interaction table surface television. A laser screen scanning device is installed on the outer surface of a television screen; when a finger or an object is in touch and carries out multichannel interaction with the outer surface of the television screen, a laser screen is intercepted by touch; a reflecting light spot image signal of man-machine interaction is formed on the surface of the screen; the signal is collected by a recognizing device and forms a recognizing control signal for being transmitted to a computer program processor device to be fused with the surface display of the television screen after analyzing man-machine interaction signals of all channels; and the recognizing control signal can also be used for starting multichannel man-machine interaction instruction executing operation, such as near field communication for carrying out communication interaction between a television and a mobile phone, and the like. The invention also discloses a method for fixing a table surface television casing and a high-thickness transparent screen base. The connecting positions of the high-thickness transparent screen base and four edges of an upper opening of a table television casing are made into a plurality of through holes for fixing screws so that the high-thickness transparent screen base is tightly fixed on the table surface television casing.

Description

technical field [0001] The invention relates to a multi-channel human-computer interaction table surface television. Background technique [0002] As we all know, most traditional TV sets are used vertically or hung on the wall or placed on a bracket or installed on the ceiling. CRT cathode ray tube TVs have radiation. In addition, the screens of CRT TVs and rear projection TVs are mainly used for The "watch only" function, although it can satisfy multiple people watching at the same time, it cannot satisfy multiple people's simultaneous operation. Only one person can use the remote control to operate. In real life, we watch TV more often sitting on the sofa, sitting In front of the coffee table, there is a certain distance from the TV with the function of "watching only". People and the screen of the TV cannot realize zero-distance interaction, and cannot realize the interaction in the real sense. With the development of mobile phones, network function TVs and interactive ...

[0002] As we all know, most traditional TV sets are used vertically or hung on the wall or placed on a bracket or installed on the ceiling. CRT cathode ray tube TVs have radiation. In addition, the screens of CRT TVs and rear projection TVs are mainly used for The "watch only" function, although it can satisfy multiple people watching at the same time, it cannot satisfy multiple people's simultaneous operation. Only one person can use the remote control to operate. In real life, we watch TV more often sitting on the sofa, sitting In front of the coffee table, there is a certain distance from the TV with the function of "watching only". People and the screen of the TV cannot realize zero-distance interaction, and cannot realize the interaction in the real sense. With the development of mobile phones, network function TVs and interactive TVs have appeared. Users have changed from "watching" TV to "using" TV, but the human-machine boundary between people and TV screens is very obvious. Although some TVs are equipped with computers and display function, but the interaction between human and TV can only be done with the help of remote control or digital set-top box or keyboard. Installed on a bracket or on a suspended ceiling. In addition, the existing TV and the mobile phone display with near-field communication function have not been able to interoperate, and the TV cannot replace the mobile phone as an Internet phone, and the TV cannot share information with the mobile phone. Although the mobile phone has a TV function, it cannot realize the integration, interaction and communication with the surface of the existing TV display screen. Due to the limitations in function and use, the existing TV has narrow uses, except for long-term viewing. Multi-channel multiplex use is very inefficient
