Eyeball tracking head-mounted display system

Abstract

The invention discloses an eyeball tracking head-mounted display system which includes a head shield, an inner lens frame, a pair of VR glasses, a rotating shaft, a pair of inner lenses, an adjustingdevice, and a rotary rod. The inner lens frame is fixed to the front end of the head shield, is shaped as a closed shell with a hollow inside, and is internally provided with an eye tracker. A see-through cover which can be opened and closed is arranged on the upper end face of the inner lens frame. The pair of VR glasses is fixed in parallel to the front end of the inner lens frame through a pairof first telescopic rods which can stretch out and draw back horizontally. The rotating shaft is horizontally and rotationally built in the front end of the head shield. The first telescopic rods arevertically and fixedly connected with the two ends of the rotating shaft. The other ends, away from the rotating shaft, of the first telescopic rods are hinged to the VR glasses. The pair of inner lenses is embedded into the inner lens frame. The rotary rod is vertically and rotationally arranged in the middle of the inner lens frame, and the lower end of the rotary rod is connected with a gear.The eyeball tracking head-mounted display system of the invention has the advantages of simple structure, convenience of use and adjustable degree, and can be widely applied to the technical field ofglass type eye trackers.

Description

Technical field [0001] The invention relates to the technical field of eye trackers. More specifically, the present invention relates to an eye-tracking head-mounted display system. Background technique [0002] Eye trackers are used to record the characteristics of human eye movement when processing visual information, and are used in many fields. For example, install an eye tracker in a car to record the driver’s eye movements, so as to provide an objective basis for car driving research; another example is to allow athletes to wear eye trackers to record their training during sports training. Eye movement data to understand the attention of athletes, so as to develop some training methods to improve the training effect of athletes. [0003] However, the existing eye tracker does not have myopic or hyperopic lenses, and it is very inconvenient for the near-sighted person or the far-sighted person to use the glasses-type eye tracker. Even if a nearsighted or hyperopic lens is i...

[0003] However, the existing eye tracker does not have myopia or hyperopia lenses, and it is very inconvenient for myopic or hyperopic people to use the glasses-type eye tracker

Even if the myopia or hyperopia lens is installed on the eye tracker, because the degree of the lens cannot be adjusted, when people with different degrees come to use it, it is very inconvenient to reinstall the appropriate lens
