Problems solved by technology

[0004] At present, the research on the human-computer interaction of the human eye sight is still in its infancy. Although there are many methods to detect the human eye sight, but because the human eye moves faster and the range is smaller when observing, most of the detection The accuracy of the method is not enough, and it has a great impact on the human eye
There are two problems in the human eye tracking system currently researched: on the one hand, it has a greater impact on people, such as helmet-type and eye-electric eye tracking systems; on the other hand, the hardware cost is relatively high

Abstract

The invention discloses a human eye tracking visual system, which belongs to the technical field of communication and comprises a light source, a controller and a power supply, An image of an object shot by the camera is focused through a lens, charges of a corresponding proportion are accumulated according to the intensity of light, the charges accumulated by all pixels are subjected to video shift, and video signal output is formed after filtering and amplification processing; And system software of the computer adopts a LabVIEW 8.5 platform, and visual auxiliary software MAX and Vision Asset 8.5 software are used as assistance. The human-computer interaction platform has the advantages that the machine vision technology and the virtual instrument are combined to build the human-computerinteraction platform which is simple and effective in human eye tracking. According to the invention, the machine vision technology and the virtual instrument are applied to human eye tracking at lowcost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a human eye tracking vision system. Background technique [0002] With the continuous deepening of research on human-computer interaction technology, multi-channel human-computer interaction has attracted much attention. The human-computer interface emphasizes the "human-centered principle", enabling users to use various sensory channels to interact with computers in the most natural way. Most of the existing human-computer interaction input is realized through the mouse, keyboard, etc., and these inputs require the cooperation of visual or auditory receiving and output information. In addition, speech recognition input technology is gradually maturing, and technologies such as understanding body posture and tactile input and output have been more researched in the intelligent virtual reality environment. [0003] When people observe the external world, the eyes always w...
