Systems and methods to provide an interactive environment over a wide field of view
Systems and methods to provide an interactive environment are presented herein. The system may include one or more of a device configured to be installed on a user's head, an image-forming component, one or more physical computer processors, and/or other components. The image-forming component may be configured to generate light rays to form images. The light rays may be reflected off an optical element towards a user's eye. The light rays may be transmitted back through a portion of the image-forming component before reaching the eye.

A method to provide an interactive environment, the method being implemented in a system comprising an image forming component held by a device configured to be installed on a head of a user, one or more physical computer processors, the image forming component having a light-providing component held by the device, and an optical element held by the device, and storage media storing machine-readable instructions, the method comprising:
generating, by the light-providing component, light rays to form images;

receiving, by the waveguide, the light rays via the optical coupling features and
selectively outputting the light rays towards the optical element;
expanding, by the diffractive surface, the light rays coming back through the waveguide; and
wherein the waveguide is positioned between the eye and the optical element when the device is installed on the head of the user, and the diffractive surface is positioned between the eye and the waveguide when the device is installed on the head of the user, such that the waveguide directs the light rays away from the eye and towards the optical element, and wherein the optical element then reflects the light rays back through the waveguide and the diffractive surface towards the eye of the user.
7. The method of claim 6 , wherein the light-generating component comprises a light source configured to generate the light rays to form the images, a beam splitter device, and a micromirror, the method further comprising:
