Detailed Description

For further explanation of the present application, the following examples are provided below, taking VR helmets as examples, to introduce the relevant structure of the virtual reality headset of the present application:

fig. 1 is a side cross-sectional view of a VR headset provided in an exemplary embodiment of the present application. As shown in fig. 1, in a device body 1 of a VR headset, a convex lens 2 and a VR player assembly 3 are assembled. Wherein the convex lens 2 is located between the user (fig. 1 shows the eyes 4 of the user) and the VR playing component 3 in the device body 1, so that VR display content played by the VR playing component 3 can penetrate through the convex lens 2 and propagate to the eyes 4 of the user based on the form of visible light S1, and the visible light S1 is received by the eyes 4 of the user and the VR display content can be viewed.

Further, a camera 5 may be mounted in the device body 1, the camera 5 is located on a side of the convex lens 2 close to the user (i.e. on the left side in the embodiment shown in fig. 1), and a lens of the camera 5 faces the eyes 4 of the user, so as to collect the eye print features of the user, and further identify the user wearing the VR headset by comparing and matching the eye print features. Compare in the identification scheme based on modes such as password input, gesture recognition among the correlation technique, this application only through installation camera 5 in the VR helmet, can gather and discern user's eye print characteristic, neither need increase complicated structure and equipment, also need not the user to carry out alone, extra operation to help promoting identification efficiency, simplify user's operation. The camera 6 may be an IR (Infrared Radiation) camera, or may also be an RGB (Red-Green-Blue ) -IR integrated camera, which is not limited in this application.

In the above embodiment, in order to avoid blocking the VR display content played by the VR playing component 3, i.e. blocking the transmission of the visible light S1, the camera 5 must be far away from the visible range of the convex lens 2 relative to the eye 4 of the user (for example, the visible range can be marked by the upper boundary T1 and the lower boundary T2 shown in fig. 1), so that the camera 5 can be mounted at the bottom of the device body 1, i.e. the camera 5 is located below the convex lens 2, and the camera 5 is rotated upward by a first preset angle to make the lens of the camera 5 face the eye 4 of the user.

Wherein, since the eyes 4 are kept in the direct-viewing state shown in fig. 1 during the use of the VR helmet by the user, so that the light ray S2 formed by the eyes 4 propagates in a substantially horizontal direction, the camera 5 necessarily forms an angle α with the light ray S2. Then, in order to avoid that the included angle α is too large to cause serious deformation of the collected eye-print features, the camera 5 may be disposed close to (including at least one of the horizontal distance and the vertical distance) the edge of the convex lens 2, i.e. the distance between the camera 5 and the eye 4 (including at least one of the horizontal distance and the vertical distance) is increased as much as possible, so as to reduce the included angle α as much as possible under the same conditions.

Further, as shown in fig. 2, the VR headset may include an adjustment assembly 6, the adjustment assembly 6 being electrically connected to the camera 5, such that even when different users use the same VR headset, the camera 5 may be angularly adjusted by the adjustment assembly 6 to ensure that the lens of the camera 5 is directed toward the eyes 4 of the user to avoid distortion or excessive distortion of the captured eyeprint features.

In the above embodiment, as shown in fig. 1, although the camera 5 has to be located outside the above visible range and cannot be located at the same height as the eye 4 in order to avoid blocking the visible light S1 in the vertical direction, the horizontal angle between the lens orientation of the camera 5 and the light ray S2 may be reduced or eliminated as much as possible in the horizontal direction, for example, since the eye 4 of the user is usually located at the middle position of the convex lens 2 in the horizontal direction, as shown in fig. 3, the camera 5 may be located at the middle position of the convex lens 2 in the horizontal direction, so as to reduce the probability of deformation or distortion of the eye-print features collected by the camera 5, or reduce the deformation or distortion of the eye-print features.

In the above embodiment, although two convex lenses 2 corresponding to both eyes of the user are included in the VR headset, for example, fig. 3 shows the right convex lens 21 corresponding to the right eye of the user and the left convex lens 22 corresponding to the left eye of the user, a single or a plurality of cameras 5 may be optionally provided according to actual situations. For example, as shown in fig. 3, the camera 5 may be provided only at the right convex lens 21 to capture the eye print feature of the right eye of the user; similarly, the camera 5 may be provided only at the left convex lens 22 to capture the eye-print feature of the left eye of the user. Of course, the cameras 5 may be disposed at the right convex lens 21 and the left convex lens 22 respectively to capture the eye pattern characteristics of the right eye and the left eye of the user simultaneously or respectively.

Of course, although in the embodiments shown in fig. 1 to 3, the cameras 5 are all located at the bottom of the apparatus body 1 and below the convex lens 2, the cameras 5 may be located at other positions, and the present application is not limited thereto. For example, as shown in fig. 4, the camera 5 may be disposed on the top of the apparatus body 1 above the convex lens 2, such that the camera 5 is rotated downward by a second preset angle, and the lens of the camera 5 faces the eye 4 of the user, so as to achieve the collection of the eye pattern feature. Then, similarly to the embodiment shown in fig. 2, the camera 5 in the embodiment shown in fig. 4 may also be electrically connected to the adjustment assembly 6 to enable angular adjustment of the camera 5; similar to the embodiment shown in fig. 3, the camera 5 in the embodiment shown in fig. 4 may also be disposed at the middle position of the corresponding convex lens 2 in the horizontal direction, so as to reduce the probability of deformation or distortion of the eye-print features collected by the camera 5, or reduce the deformation or distortion of the eye-print features, which is not described herein again.

Fig. 5 is a side cross-sectional view of a VR headset provided in an exemplary embodiment of the present application. As shown in fig. 5, the VR helmet may be a split VR headset, and a device interface 7 may be assembled in a device body 1 of the VR helmet, so that the device interface 7 may be electrically connected to an electronic device such as a mobile phone and a tablet installed in the device body 1; the electronic device can realize rendering processing through a processor, a display card chip and the like, display content through a screen component and the like, and is used as a VR playing component 3 in the device body 1.

Further, the camera 5 in the device body 1 may be connected to the device interface 7 through a data line 8, so that when the electronic device connected to the device interface 7 issues a switch control instruction, the camera 5 may receive the switch control instruction through the device interface 7 and the data line 8, thereby performing a switch state switching operation in response to the switch control instruction. In other words, based on the user's operation of the electronic device or based on the control of the application program running on the electronic device, the electronic device may send a switch control instruction to the camera 5, and control the camera 5 to collect the eye pattern features of the eye 4, so that the controllability of collecting the eye pattern features is improved.

In addition, after the camera 5 finishes the collection of the eye print characteristics, if a processing module is arranged in the VR helmet, the collected eye print characteristics can be transmitted to the processing module for processing; alternatively, the camera 5 may transmit the collected eye print features to the electronic device via the device interface 7 and the data line 8 for processing by the electronic device.

Of course, the VR helmet of this application can include the split type VR head mounted device of other forms besides can be with electronic equipment matched with such as cell-phone. For example, for a split VR headset, the VR headset may be matched with a PC host, a game host, or other external devices, the VR playing component 3 may be a display component built in the VR headset, and the external devices are used to implement rendering processing of VR display content. For another example, the VR helmet may be an integrated VR headset, that is, when the VR helmet can autonomously realize a VR playing function without an external device, the VR playing component 3 is pre-embedded in the VR helmet, and the VR playing component 3 may realize playing functions such as rendering, displaying, and the like of VR display content.
