The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The embodiment of the present invention provides a head-mounted display device, including: a wearable component, an optical device, a display device, a camera, an electronic processor and a battery, as shown in FIG. 1 , the head-mounted display device of the present invention is also include:

The eyeball recognition and sensing device 106 is arranged on the side of the wearable component close to the eyeball and connected with the electronic processor 104 to recognize and sense the wearer's eyeball.

In the embodiment of the present utility model, the optical device 101, the display device 102, and the camera 103 are also connected to the electronic processor 104, and the battery 105 is in phase with the optical device 101, the display device 102, the camera 103, the electronic processor 104 and the eyeball recognition sensing device 106. Connect to provide power to each device.

In the embodiment of the present invention, the eyeball recognition sensing device is: an eyeball tracking device and/or an iris recognition sensor.

In the embodiment of the present utility model, the eye recognition sensing device is: an optical infrared sensing lens.

In the embodiment of the present invention, the eyeball recognition sensing device is a camera.

In the embodiment of the utility model, the wearing component is a spectacle frame or a helmet. As shown in Figure 2, it is a schematic diagram of an embodiment of the present invention. The wearable component is a spectacle frame. The head-mounted display of this embodiment includes the following parts: including an optical module, a see-through display device 6, and an eye tracking sensor that is the aforementioned The eyeball recognition sensing device (located on the inner side of the frame connector 3), the camera (located on the outside of the frame connector 3), the electronic processor and the battery, in this embodiment, the optical modules are respectively arranged at the temple position 2 and the temple At position 5, the electronic processor and battery are located at position 1 on the temples marked in the figure.

The eye tracking sensor of this embodiment can capture iris information of the human eye at the same time, and realize identity authentication through iris recognition.

An operating system and software are running on the electronic processor, and a displayed video image is generated according to the operation of the program, and the video image is transmitted to the optical module, and the video image is presented on the see-through display device 6 .

The eye tracking sensor is set on the frame of the glasses close to the eyeball, and is located inside the frame of the glasses, which is convenient for capturing eye movements. The eye tracking sensor can be an optical infrared sensing lens device, or other eye tracking devices, such as a camera. The optical infrared sensing lens device can use infrared light to trace the enlargement, reduction and position change of the pupil, and then perform data analysis and lock the seen image through calculation, and the effect is better. Combining smart head-mounted displays with eye-tracking sensors can enable many new interactive features, such as when the user looks away from the video or content that is being played, the video will automatically stop playing, and when the user reads to the bottom of the text Automatic page turning, etc.

The eye tracking sensor can also be an iris recognition sensor. The iris recognition sensor can also be an optical infrared sensing lens device, or a camera capable of collecting iris images. Among them, the optical infrared sensor lens device has higher precision and better recognition effect. When working, the sensor captures the image of the iris and transmits it to the electronic processor, and the electronic processor compares the obtained iris image with the existing image, and the identity verification is completed after the comparison is confirmed to be correct.

The utility model utilizes the eyeball tracking technology. When the eyeballs look in different directions, there will be subtle changes in the eyes, and these changes will produce features that can be extracted. The computer can extract these features through image capture or scanning, so as to track in real time Changes in the eyes, predict the user's status and needs, and respond to achieve the purpose of controlling the device with the eyes. The main equipment of eye tracking technique includes infrared equipment and image acquisition equipment. In terms of accuracy, the infrared projection method has a relatively large advantage. It can be accurate to within 1 cm on a 30-inch screen. With the help of technologies such as blink recognition and gaze recognition, it can already replace the mouse and touchpad to a certain extent. Some limited operations. In addition, other image acquisition devices, such as cameras on computers or mobile phones, can also achieve eye tracking with the support of software, but there are differences in accuracy, speed and stability.

The iris recognition adopted in the embodiment of the utility model is also a method of identifying people's identity that has just emerged in recent years. Compared with other identification methods, it has three significant advantages: uniqueness, invariance and non-invasiveness. Iris recognition is an identification method with the highest recognition rate so far. Iris recognition consists of four steps: image acquisition, iris localization, feature extraction, and pattern matching. Among them, the acquisition of iris image is the first step in iris recognition, and it is also the most difficult step. Due to the special nature of the iris: small area and dark color, ordinary cameras cannot capture iris images that can be used for identification. There are great differences in the iris color of different races. Caucasian irises are light in color and have obvious textures, while yellow people's irises are mostly dark brown with very inconspicuous textures. Using infrared lighting can solve this problem very well.

In the utility model, specific examples have been applied to explain the principle and implementation of the utility model, and the explanations of the above examples are only used to help understand the method of the utility model and its core idea; meanwhile, for those of ordinary skill in the art According to the idea of the present utility model, there will be changes in the specific implementation and scope of application. In summary, the content of this specification should not be construed as a limitation of the present utility model.
