Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the specific contents of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a perspective type near-to-eye display device capable of automatically adjusting display contents, including:
a main control system, a near-eye display and a lens focus detector; wherein,
the lens focal length detector is arranged on the near-eye display, is in communication connection with the main control system, can detect the lens focal length of a user and sends the lens focal length to the main control system;
the main control system is in communication connection with the near-eye display and can judge whether the focus of the eyes of the user is on the virtual display screen of the near-eye display according to the received lens focal length of the user, if so, the near-eye display is controlled to normally output images, and if not, the near-eye display is controlled to close image output.
In the above-mentioned near-eye display device, the main control system determining whether the focus of the user's eye is on the virtual display screen of the near-eye display device is: if the focal point is at a preset focusing distance (such as 3 meters, 3.5 meters, 4 meters or other distances), determining that the focal point of the user's eye is on the virtual display screen of the near-eye display, otherwise determining that the focal point of the user's eye is not on the virtual display screen of the near-eye display.
The embodiment of the present invention further provides a perspective type near-to-eye display method for automatically adjusting display content, which adopts the above perspective type near-to-eye display device for automatically adjusting display content, and includes the following steps (see fig. 2):
detecting the lens focal length of the user through a lens focal length detector of the device and sending the detected lens focal length to a main control system of the device;
and the main control system of the device judges whether the focus of the eyes of the user is on the virtual display screen of the near-eye display according to the received lens focal length of the user, if so, the near-eye display is controlled to normally output images, and if not, the near-eye display is controlled to close image output.
The embodiments of the present invention will be described in further detail below.
An embodiment of the present invention is shown in fig. 1, wherein the near-eye display is a device commonly used in augmented reality technology, and functions to generate a virtual display (shown by dotted lines) at a certain distance in front of the eyes of the user (for example, the virtual display is displayed 3 meters in front of the eyes of the user). The near-eye display is connected with the main control system, the displayed content and whether the display is controlled by the main control system, and the crystalline lens focal length detector is arranged on the near-eye display and used for detecting the crystalline lens focal length of a user and inputting the focal length to the main control system. The main control system acquires the focal length of the crystalline lens of the user and judges whether the focal point of the eyes of the user is on the virtual display screen. If the user's eyes are focused on the virtual display screen, for example, the focus is at a distance of 3 meters, the main control system controls the near-eye display to normally output the image, and the user can see the virtual image. On the contrary, if the focal point of the eyes of the user is not on the virtual display screen, for example, the focal point is not on the distance of 3 meters, the main control system controls the near-eye display not to output the image, and the user can directly see the real world without the interference of the virtual image.
Furthermore, the specific mode of outputting the image by the near-eye display of the present invention may be lighting the backlight of the display screen, displaying the content on the display screen, or combining the two; accordingly, the specific way of the near-eye display not outputting the image may be to turn off the backlight of the display screen, or the display screen may not display the content or display pure black, or the combination of the two.
In the perspective near-eye display system, when a user watches virtual information, the focal length of the crystalline lens is adjusted to the focal length corresponding to the virtual display screen, the near-eye display outputs a display image, and the virtual information is displayed. When the user does not see the virtual information, the near-eye display does not output the display image, the virtual information is not displayed, and the user directly sees the real world. Thus, the situation that the virtual information interferes with the real world can be eliminated.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
