Description
Technical field
The present invention relates to TV technologies, and in particular to a kind of personal identification method and system based on movement posture.
Background technique
As internet content enters television field, the content type televised is very more, and very numerous and jumbled, uses
Family requires a great deal of time when looking for program and energy, therefore the various recommendation applications about content emerge one after another.
But for family's shared device such a for TV, kinsfolk is different for the demand of content,
So simple commending contents effect is little, and if can recognize that it is currently who is seeing TV, then according to this people's
Viewing history does correlation type recommendation, then the hit rate of commending contents will be greatly improved.
In the prior art, multi-user system can be set inside some system for TV set, after television boot-strap, provide a boundary
Face selects active user for spectators, but this causes user be switched on every time will select user, cumbersome, and there are also selection mistakes
Accidentally a possibility that.
Also the television set having configures multiple remote controlers, everyone is equipped with a different remote controler to kinsfolk, leads to
Different remote controlers is crossed to distinguish different users, but will lead to the increase of television set manufacturing cost in this way, and for user
For, it will also result in that user's family remote controler quantity increases, loses, mistake is taken by mistake and put, when user can not find oneself remote controler
In the case of, can also others' remote controler be taken to manipulate TV, then destroy the accuracy rate of personalized recommendation.
Also have by installing fingerprint identification module on a remote control, user presses fingerprint, then passes through when picking up remote controler
Fingerprint is passed to TV by wireless module, then judges to be which user, but also results in manufacturing cost height in this way, and use
Family is cumbersome, also has the hidden danger of fingerprint leakage.
