Abstract
The invention relates to an intelligent home controller based on eye-movement tracking and an intelligent home control method based on eye-movement tracking, and belongs to the field of wireless control. The problem that the existing intelligent home controller adopts a press key or touch input mode, so that the existing intelligent home controller cannot be applicable to special user groups with limb obstacles. The intelligent home controller based on eye-movement tracking comprises an image collecting module, an image processing module, a communication module, an FPGA (Field Programmable Gate Array) module and a sub module, wherein the sub module is integrated inside an FPGA chip. The intelligent home control method based on the eye-movement tracking comprises the steps that: the image processing module performs binarization processing on collected face images; the human eye pupils and the light spot positions, displayed on the human eye scleras, of an infrared lamp are found out; the sight line direction of the human eye is estimated; and in a VGA (Video Graphics Array) liquid crystal display, the designed user interface and the user slight line position are displayed in the liquid crystal display screen by the image display module, and the human-computer interaction is realized. A non-contact control mode is adopted, so that the interference on users is reduced to the greatest degree, and the burden of the user is lightened.
Description
technical field [0001] The invention relates to an eye-tracking smart home controller and a control method thereof. Background technique [0002] Smart Home is the embodiment of connectionization under the impact of Internet of Things. The smart home system connects various existing household devices together through network technology, and provides various functions and means such as home appliance control, lighting control, telephone remote control, and environmental monitoring. Smart homes not only have traditional residential functions, but also include construction, network communications, information appliances, and equipment automation, providing a full range of information interaction functions, and even saving energy costs for occupants. [0003] The operation terminal with wireless communication function can enable the occupants to conveniently control the household appliances and obtain the required information. Existing wireless operation terminals include smar...
