Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model provides a kind of demo system based on Eye Tracking Technique, this system comprises be used to the camera glasses that obtain eye image information, be used for to transmit the sensor of image information, carry out the treatment facility of sight line location and be used for the response apparatus of result feedback for the treatment of image information; Described camera glasses link to each other with treatment facility by the built-in sensors that wireless camera carries, and can carry out sensing by modes such as wifi or bluetooths, and the output terminal of sensor links to each other with treatment facility, and the output terminal for the treatment of facility links to each other with response apparatus.
In technique scheme, described response apparatus comprises other transaction response processing modules such as location indicating module, page turning zoom operations module.
In technique scheme, described treatment facility is PC or for mobile phone or for panel computer.
As shown in Figure 2, be workflow diagram of the present utility model, its step is as follows:
1, obtain the image information very nearly the same with the human eye capturing information that camera is caught by the camera glasses of wearing, wherein information source can be the display for the treatment of facility or the image on the projection panel;
2, treatment facility carries out pre-service with the image information of obtaining, and is processed into gray level image so that routine analyzer carries out next step operation;
The edge that 3, can not be in image according to human eye by many images the Analysis deterrmination picture centre and set up image coordinate;
4, go out the coordinate of sight line focus according to Characteristic of Image information calculations after processing, carry out simultaneously coordinates correction;
