Infrared human-computer interaction method and device

Abstract

The invention discloses an infrared human-computer interaction method and an infrared human-computer interaction device. The infrared human-computer interaction device comprises a remote controller and an intelligent television. The method comprises the following steps of: shooting images, and acquiring a plurality of infrared light spot images on the remote controller which is provided with infrared light emitting diodes (LED); processing the images, and determining the spatial position and attitude of the remote controller according to the position and arrangement of the infrared LED light spot images; and controlling the cursor position of the intelligent television according to the spatial position of the remote controller, and making a corresponding gesture by the intelligent television according to the attitude of the remote controller. The infrared human-computer interaction device comprises an image shooting and processing device which is arranged on one side of the intelligent television; at least three infrared LEDs are arranged on the top of the remote controller and staggered at intervals two by two; and the image shooting and processing device comprises an image shooting module, an image processing module, a gesture processing module and an interface module. By the invention, the cursor position of the intelligent television can be accurately controlled, and gesture identification operation such as rotation and scaling can be quite conveniently accomplished.

Description

Technical field [0001] The invention relates to the field of human-computer interaction of smart TVs, in particular to an infrared human-computer interaction method and device. Background technique [0002] Similar products currently on the market are: UWAND from Philips, WII from Nintendo, and MOVE from Sony. Among them, UWAND and WII use the remote control / handle to install a camera device, and multiple infrared LEDs are placed on the side of the TV. After the remote control / handle end computing unit receives the image obtained by the camera device, it obtains the current remote control movement status. Sony's MOVE uses an infrared light-emitting sphere at the end of the handle. The infrared light ball is photographed by a camera device measured by a TV. Then the coordinates of the handle are obtained by identifying the size and position of the ball. In addition, WII and MOVE also have an additional sensor to obtain the current position and movement of the handle. [0003] In ...

Problems solved by technology

[0005] 2) Since the camera device consumes a lot of power, it generally needs a charging circuit, which cannot achieve the low energy consumption of traditional remote controls

[0006] Sony's MOVE solution: Since there is a rather large ball in the front of the handle, if it is used as a remote control, the shape is rather weird, and it cannot achieve the shape of a traditional remote control.
