Non-contact virtual human-computer interaction method based on smart television set

The invention discloses a non-contact virtual human-computer interaction method based on a smart television set; the method comprises the steps: step 1, connecting to the smart television set to image sensing equipment, establishing a gesture identification system and a gesture information database in the smart television set, and storing a plurality of appointed gestures as well as smart television set executing programs in one-to-one correspondence association with the appointed gestures in the gesture information database; step 2, setting two operational models; step 3, directly operating a two-dimensional menu interface and a three-dimensional control interface switched by the gestures in the smart television set when the operational model A is carried out; and step 4, when the operational model B is carried out, keeping the present interface of the smart television set unchanged and calling the smart television set executing programs correspondingly associated with the gestures. The non-contact virtual human-computer interaction method based on the smart television set has the beneficial effects of exploring users' interaction purposes in the combination of virtual interface location awareness and users' behavior models and providing a new way for solving the 'Midas Touch Problem' which is difficult to be solved on the basis of a gesture interaction human-computer system.
