Description

Interaction method and system for a smart TV

technical field

The invention relates to the field of human-computer interaction, in particular to an interaction method and system for a smart TV.

Background technique

On June 9, 2010, the introduction of the national triple play (cable TV network, telecommunication network, and computer communication network) policy has made televisions and the Internet more and more closely integrated, and smart TVs based on triple play TV will become an important direction of future development, more and more exciting content will enter the TV screen, and the living room will gradually become a home entertainment center. However, while the functions and content provided by the smart TV system are more abundant, how to operate the system through a convenient, concise and effective human-computer interaction method to obtain the content desired by the user is the main problem currently faced.

In response to this problem, some manufacturers at home and abroad have also launched some technical products, which can be divided into three categories in terms of function and form: the first category is to expand the ordinary remote control and add some buttons. Remote control, this type of remote control generally has more than 40 buttons. On the one hand, it is more complicated to use, and on the other hand, it cannot really meet the interactive needs of smart TVs. The second category is to integrate and miniaturize the computer keyboard and mouse. Although this type of product has relatively strong functions, it is different from the close interaction between the computer and the user because of the remote interaction between the TV and the audience. It is still very inconvenient to interact with the TV screen. The third category is the so-called somatosensory interaction, which is mainly represented by gesture recognition. This kind of interaction looks beautiful, and it will feel fresh in a short time, but there are many problems in long-term use (you have to dance around when changing channels while watching TV), and there is still a long way to go before it is truly practical.

In fact, the TV remote control is the most familiar and convenient interactive device for users to use. However, due to the small number of buttons on the ordinary remote control, simply using the ordinary remote control cannot meet the interactive needs of smart TVs.

Contents of the invention

In order to solve the above problems, the purpose of the present invention is to disclose a smart TV interaction method and system, which is to solve the above-mentioned problems existing in the smart TV interaction. The content to be watched is placed at the front, and the user only uses the 10 number keys on the ordinary remote control and a few function keys such as up, down, left, and right to interact.
