Embodiment Construction

[0040] A smart TV-based non-contact virtual human-computer interaction method of the present invention, in order to reduce the influence of the "Midas Touch problem" in the process of operating the virtual interface for the user, and eliminate possible interference between different functional areas, the present invention uses the user Combining behavior model and virtual interface, an implicit interaction paradigm based on user behavior model and virtual interface is proposed. Include the following steps:

[0041] Step 1, connecting the smart TV to the image sensing device, and establishing a gesture recognition system and a gesture information database in the smart TV, storing several specified gestures and a smart TV execution program associated with the specified gestures in a one-to-one correspondence in the gesture information database;

[0042] Step 2, if the image sensing device observes that a user draws a rectangle in the perception space in front of the smart TV, pr...

Abstract

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.

Description

technical field [0001] The invention relates to a non-contact virtual human-computer interaction method based on a smart TV. Background technique [0002] In recent years, three-dimensional (3D) natural gesture interaction technology has been applied in sign language recognition, finger mouse, virtual object control, home appliance remote control, Windows command control, finger painting, robot control and other fields. Natural, efficient, intelligent, and barrier-free human-computer interface (HCI, Human-Computer Interface) has become the main development direction of the new generation of intelligent HCI, to establish an intelligent, natural, harmonious, humanized human-computer interface It has become the main trend of the development of the new generation of HCI. [0003] Among the graphic interfaces widely used at present, the main input methods are physical keyboard and touch screen input. Of course, touch screen technology occupies the mainstream in mobile terminals ...
