This application claims the benefit of Chinese Patent Application No. 201720127665.8, filed with the Chinese Patent Office on Feb. 10, 2017 and entitled “A smart user experience apparatus and a smart helmet”, which is hereby incorporated by reference in its entirety.
The present application relates to the field of user experience technologies, and particularly to a smart user experience apparatus and a smart helmet.
Augmented reality (AR) (VR) is a new display mode further to a 3D display mode, which is used to enhance a human-environment interaction experience. A sensor loaded in an AR helmet can detect and track a moving head and eyes of a user constantly, and track user data, so that virtual information can be overlaid on the real word, by simulating and integrating physical information, which would otherwise be difficult to experience for some time and in some space, into the real world.
However, the existing AR helmet in use may be unfriendly to nearsighted or farsighted users in that an experiencing user has to wear his or her glasses due to his or her problematic vision, so that his or her eyes are pressed for a long period of time, thus seriously degrading his or her experience.
An embodiment of the application provides a smart user experience apparatus including a display device and a watching device, where the display device is configured to provide the watching device with virtual information, and the watching device is configured to present the received virtual information to an experiencing user, or to integrate the received virtual information with reality information, and then present the integrated information to the experiencing user; and the smart user experience apparatus further includes:

an image source configured to provide the eyes of the experiencing user with a test image;
a set of lenses, located on the side of the image source facing the experiencing user, composed of a plurality of lenses with their light axes coincide with each other, where the test image provided by the image source arrives at the eyes of the experiencing user through the set of lenses;

a vision correction device 4, located on the side of the watching device 2 facing the experiencing user, connected with the detecting device 3, and configured to compensate for the vision of the experiencing user according to the diopters detected by the detecting device 3.
Particularly in the smart user experience apparatus above according to the embodiment of the application, the diopters of the eyes of the experiencing user can be detected by the detecting device 3 located on the side of the watching device 2 facing the experiencing user, and thereafter the vision of the experiencing user can be compensated for by the vision correction device 4 located on the side of the watching device 2 facing the experiencing user according to the diopters detected by the detecting device 3, so the visions of experiencing users with the different visions can be compensated differently for, so that a nearsighted or farsighted experiencing user can see a clear image during watching even without wearing his or her glasses, thus eliminating his or her feeling of a pressure on his or her eyes while the experiencing user is wearing his or her glasses as in the prior art.

Particularly human eyes are nearsighted or farsighted because parallel light rays passing lenses of the eyes are not converged onto the retinas, so the lens structure 41 can be equivalent to lenses. The curvature radius of the lens structure 41 is adjusted according to the diopters of different eyes so that the lenses of the eyes match the lens structure 41, and in this way, an image of the watching device 2 can be imaged clearly onto the retinas of the experiencing user, that is, the image of the watching device 2 can be seen clearly by the experiencing user.
