[0002] Virtual reality is generally considered to be a computer generated simulated environment where a used has an apparent physical presence. A virtual reality experience can be generated in 3D and viewed with a head-mounted display (HMD), such as glasses or other wearable display devices that have near-eye display panels as lenses to display a virtual reality environment that replaces an actual environment.

[0003] Augmented reality, however, enables an experience in which a user can still see through the display lenses of the glasses or other HMD device to view the surrounding environment, yet also see images of virtual objects that are generated for display and appear as part of the environment. Augmented reality can include any type of input, such as audio and haptic inputs, as well as virtual images, graphics, and video that enhances or augments the environment that the user experiences. As an emerging technology, there are many challenges and design constraints with augmented reality.

[0019] Embodiments of the present disclosure generally relate to augmented reality devices. More specifically, augmented reality devices having a waveguide with a user field of view (FOV) on an user side (eye-side) and a world FOV on a worldside. The user FOV is a point at which a user perceives the virtual images of an augmented reality display. The user FOV is determined by the angle of light reflected to the user’s eye from the outcoupler grating. The light projects content (e.g., an image or text) toward the user. Light exits the waveguide through the world-side of the waveguide at the same angle it is projected into the waveguide by the incoupler. Light that exits the waveguide on the world-side of the waveguide is referred to as eye glow. Eye glow can be seen by observers near the user. As described herein, eye glow can be used to create a world FOV. The world FOV includes a forward projection that can be customized by the user to display varying content, such as text or images, on the world-side of the augmented reality device.

[0020] Figure 1 is a perspective, frontal view of a waveguide 100. It is to be understood that the waveguide 100 described herein is an exemplary waveguide and that other waveguides may be used with or modified to accomplish aspects of the present disclosure. The waveguide 100 includes a plurality of structures 102. The structures 102 may be disposed over, under, or on a surface 103 of a substrate 101 , or disposed in the substrate 101. The structures 102 are nanostructures having a sub-micron critical dimension (e.g., a width less than 1 micrometer). Regions of the structures 102 correspond to one or more gratings 104. In one embodiment, which can be combined with other embodiments described herein, the waveguide 100includes at least an incoupler 104A (e.g., a first grating) and an outcoupler 104C (e.g., outcoupler grating). In another embodiment, which can be combined with other embodiments described herein, the waveguide 100 further includes an intermediate grating 104B. The intermediate grating 104B corresponds to a pupil expansion grating (“pupil expander”) or a fold grating.

[0021] In operation, the incoupler 104A receives incident beams of light having an intensity from a light engine. The incident beams are split by the structures 102 into T 1 beams that have all of the intensity of the incident beams in order to direct a virtual image to the intermediate grating (if utilized) or to the outcoupler 104C. In one embodiment, which can be combined with other embodiments described herein, the T1 beams undergo total-internal-reflection (TIR) through the waveguide 100 until the T1 beams come in contact with the structures 102 of the intermediate grating. The structures 102 of the intermediate grating diffract the T1 beams to T-1 beams that undergo TIR through the waveguide 100 to the structures 102 of the outcoupler 104C. The structures 102 of the outcoupler 104C outcouple the T1 beams to the user’s eye. The T1 beams outcoupled to the user’s eye display the virtual image produced from the light engine from the user’s perspective and further increase the viewing angle from which the user can view the virtual image. In another embodiment, which can be combined with other embodiments described herein, the T1 beams undergo total- internal-reflection (TIR) through the waveguide 100 until the T1 beams come in contact with the structures 102 of the outcoupler 104C and are outcoupled to display the virtual image produced from the light engine. In one or more embodiments, the user image and the observer image undergoes a partial internal reflection. For example, theT1 beams may escape from the waveguide before the T1 are outcoupled to the user’s eye, causing a partial (e.g., less than total) internal reflection of the T1 beams.

[0022] Figure 2A is a perspective, frontal view of a waveguide 100 device depicting a user field of view (FOV) 202 and a world FOV 204 during operation. Figure 2B representative, schematic view of an augmented reality device in operation. As shown in Figure 2A, the waveguide 100 includes a user FOV 202 and a world FOV 204. The front view, as shown in Figure 2A, of the waveguide 100 faces the user 212. The user FOV 202, as shown in Figure 2A, depicts an example of what a full display of an waveguide 100 may feature. For example, the waveguide 100 features the userFOV 202 as at least 50% of the display. The user FOV 202 is in at least the upper portion of the waveguide 100. The user FOV 202 is a point where the user 212 perceives the user images of an augmented reality display (user content). The world FOV 204 includes a plurality of world content zones 206 (e.g., a first content zone 206a, a second content zone 206b, and a third content zone 206c). Each world content zone 206 may display a message, an image, or a symbol viewable to observers 214 on the world side of the waveguide 100. A shown in Figure 2A, the user 212 side of the waveguide 100 the content displayed in the content zone (e.g., the first content zone) appears inverted on the user facing side of the waveguide 100.

[0023] As shown in Figure 2B, the waveguide 100 is in front of the user 212 with observers 214 stationed in front of the user 212 at different angles. Each observer 214 may see a different image in a content zone (e.g., a first content zone 206a). For example, a first observer 214a may view the first content zone 206a because the eye glow path 216a is viewable by the first observer 214a. The plurality of eye glow paths 216 include light that travels through the waveguide and exits the outcoupler 104C toward the world side of the waveguide 100. The user 212 can select what content to display to any observer 214. For example, the user 212 may select an image to display in one of the world content zones 206 (e.g. , the first content zone 206a). World tracking cameras (not pictured) disposed within the waveguide 100 capture locational information of observers 214 in the world. The locational information is used by the waveguide 100 to display content in a location on the world FOV 204 so that the observer 214 can see the user’s 212 selected content. As another example, as shown in Figure 2B, a second observer 214b is at a location where the eye glow 216b is visible. In this example, the second content zone 206b displays a phone image, the second observer 214b can see this image at their location in Figure 2B. As a further example, as shown in Figure 2B, a third observer 214c is at a location where the third observer 214c may see through the waveguide 100 and view the user’s 212 eyes (e.g., the third observer 214c will not see directed content in the world content zones 206 of the world FOV 204 on the waveguide 100 because there is no eye glow path 216 directed towards the third observer 214c).

[0024] Figure 3 is a schematic, side view of a portion of a waveguide 100 in operation. Figure 3 shows the portion waveguide 100 including an outcoupler 104C. Further, Figure 3 shows a user side 322 of the waveguide 100, which includes a user212, and a world side 320 of the waveguide 100, which includes an observer 214. A horizontal plane 416 is shown in Figure 3 that is parallel to an eye of a user 212 and an observer 214. A projector 304 projects a plurality of images 308 to the incoupler 104A at a plurality of varying angles 700. The plurality of images 308 includes at least a first user image 400 at a first user angle 700a, a first observer image 600 at a first observer angle 700d, a border image 500 at a border angle 700c, a second user image 406 at a second user angle 700b, and a second observer image 606 at a second observer angle 700e.

[0025] The plurality of images 308 are incoupled into the waveguide 100 via the incoupler 104A and are outcoupled via the outcoupler 104C. The plurality of images 308 projected from the projector 304 results in at least one user image to be projected into the user FOV 202. The plurality of world side images 310 exiting the outcoupler 104C on the world side 320 includes the same angles as the plurality of varying angles 700. The plurality of user side images 312 exiting the outcoupler 104c on the user side 322 exit at a different angle than the plurality of varying angles 700. The angle of the plurality of user side images 312 exiting the outcoupler 104C on the user side 322 can be controlled by the position of the outcoupler 104C on the waveguide 100 or the size of the outcoupler 104C on the waveguide 100. For example, a smaller outcoupler 104C that is located in an upper portion of the waveguide 100 may direct an image above a user’s 212 eye. Further, the angle of the plurality of images 308 projected from the projector 304 may be adjusted to change the angle the light will reflect towards the user 212. The adjustment of the angle of the plurality of images 308 controls if the content is projected onto the user FOV 202 or onto the world FOV 204. As shown in Figure 3, the plurality of images 308 are projected from the projector 304 at multiple different angles, this causes user side images 312 to be reflected to the user FOV 202 and world side images 310 project onto the world FOV 204 at the same time. This allows for user FOV 202 content and world FOV 204 content to be projected in the waveguide 100 simultaneously. When user side images 312 are projected along or close to the horizontal plane 306 toward the eye of the user 212, the user will perceive the image, and, therefore, the content, in the user FOV 202.

[0026] Figures 4B and 4D are schematic, side views of a portion of a waveguide 100 depicting light projecting to a user FOV 202, according to at least one embodiment. Figures 4A and 4C are front views of a waveguide 100 depicting a userFOV 202 and a world FOV 204, according to at least one embodiment. A horizontal plane 416 is shown in both Figures 4B and 4D that is parallel to an eye of a user 212 and an observer 214. As shown in Figure 4B, a first user image 400 is projected from the projector 304 to the waveguide 100, and the first user image 400 leaves the waveguide 100 through the outcoupler 104C. The first user image 400 is projected into an incoupler 104A at a first user angle 700a. The first user image 400 is outcoupled to the user 212 on the user side 418 of the waveguide 100 as an outcoupled first user image 402. The outcoupled first user image 402 is projected along, below or close to the horizontal plane 416. The user 212 will perceive the outcoupled first user image 402 and will perceive the content 412 in the user FOV 202 of the waveguide 100, as shown in Figure 4A. For example, content 412 appears in the top left of the user FOV 202. However, it should be understood the content 412 may appear anywhere in the user FOV 202. The first user image 400 that passes through the outcoupler 104C to the world side 420 passes through as a first world side image 404. The angle of the first world side image 404 leaving the outcoupler 104C is the same as the first user angle 700a. As shown in Figure 4B, the first world side image 404 includes a downward angle that is below an observer 214. The downward angle of the first world side image 404 that is below the horizontal plane 416 allows for the first world side image 404 to travel outside the observer’s 214 field of view (e.g., there is no content visible in the world FOV 204).

[0027] As shown in Figure 4D, a second user image 406 is projected from the projector 304 to the waveguide 100. The second user image 406 is projected into an incoupler 104A at a second user angle 700b. The second user image 406 leaves the waveguide 100 through the outcoupler 104C. The second user image 406 is outcoupled to the user 212 on the user side 418 of the waveguide as an outcoupled second user image 408. The outcoupled second user image 408 is projected along, below, or close to the horizontal plane 416. The user 212 will perceive the second user image 408 and will perceive the content 414 in the user FOV 202 of the waveguide 100, as shown in Figure 4A. For example, content 414 appears in the top right of the user FOV 202. However, it should be understood the content 414 may appear anywhere in the user FOV 202. The second user image 406 that passes through the outcoupler 104C to the world side 420 passes through as a second world side image 410. The angle of the second world side image 410 leaving the outcoupler104C is the same angle the second user image 406 entered the waveguide 100 from the projector 304. As shown in Figure 4D, the second world side image 410 includes a downward angle that is below an observer 214. The downward angle of the second world side image 410 that is below the horizontal plane 416 allows for the second world side image 410 to travel outside the observer’s 214 field of view (e.g., there is no content visible in the world FOV 204).

[0028] Figure 5A is a schematic front view of a waveguide 100 depicting a user FOV 202 and a world FOV 204. Figure 5B is a schematic, side view of a portion of a waveguide 100 depicting light projecting to a user FOV 202 and a world FOV 204. A horizontal plane 506, as shown in Figure 5B, is parallel to an eye of a user 212 and an observer 214. As shown in Figure 5B, a border image 500 is projected from the projector 304 to the waveguide 100. The border image 500 is projected into an incoupler 104A at a first user angle at a border angle 700c. The border image 500 leaves the waveguide 100 through an outcoupler 104C. The border image 500 is reflected to the user 212 on the user side 510 of the waveguide 100 as user side border image 502. The user side border image 502 is projected just above the eye of the user 212, close to the horizontal plane 506. The border image 500 that passes through the outcoupler 104C to the world side 512 passes through as a world side border image 504. The angle of the world side border image 504 leaves the waveguide 100 at the same angle the border angle 700c. As shown in Figure 5B, the world side border image 504 includes an angle that is close to the horizontal plane 506. As shown in Figure 5A, content 508 is projected along a boundary 516 between the user FOV 202 and the world FOV 204 of the waveguide 100. The content 508 is perceived by both the user 212 and the observer 214. Both the user 212 and the observer 214 perceive the content 508 because the user side border image 502 and the world side border image 504 is projected close to or along the horizontal plane 506.

[0029] Figures 6A and 6C are front views of a waveguide 100 depicting a user FOV 202 and a world FOV 204. Figures 6B and 6D are schematic, side views of a portion of a waveguide 100 depicting light projecting to an world FOV 204. A horizontal plane 616 is shown in both Figures 6B and 6D that is parallel to an eye of a user 212 and an observer 214. As shown in Figure 6B, a first observer image 600 is projected from a projector 304 to a waveguide 100. The first observer image 600 is projected into anincoupler 104A at a first observer angle 700d. The first observer image 600 leaves the waveguide 100 through an outcoupler 104C. The first observer image 600 is outcoupled to the user 212 on the user side 618 of the waveguide 100 as an outcoupled third user image 602. The outcoupled third user image 602 is projected outside of the user’s 212 field of vision because the outcoupled third user image 602 is projected at an angle above the horizontal plane 616 (e.g., no content is visible in the user FOV 202). The first observer image 600 that passes through the outcoupler 104C to the world side 620 passes through as a third world side image 604. The angle of the third world side image 604 leaving the outcoupler 104C includes the same angle as the first observer angle 700d. As shown in Figure 6B, the third world side image 604 includes a slight upward angle close to or along the horizontal plane 616. The observer 214 will perceive the third world side image 604 traveling along or near the horizontal plane 616, and, therefore, the observer 214 will perceive content 612 in the world FOV 204. For example, as shown in Figure 6A, content 612 appears in the bottom left corner of the world FOV 204. However it should be understood that content 612 may appear anywhere in the world FOV 204.

[0030] As shown in Figure 6D, a second observer image 606 is projected from a projector 304 to a waveguide 100. The second observer image 606 is projected into an incoupler 104A at a second observer angle 700e. The second observer image 606 leaves the waveguide 100 through an outcoupler 104C. The second observer image 606 is outcoupled to the user 212 on the user side 618 of the waveguide 100 as an outcoupled fourth user image 608. The outcoupled fourth user image 608 is projected outside of the user’s 212 field of vision because the outcoupled fourth user image 608 is projected at an angle above the horizontal plane 616 (e.g., no content is visible in the user FOV 202). The second observer image 606 that passes through the outcoupler 104C to the world side 620 passes through as a fourth world side image 610. The angle of the fourth world side image 610 leaving the outcoupler 104C includes the same angle as the second observer angle 700e. As shown in Figure 6D, the fourth world side image 610 includes a slight upward angle close to or along the horizontal plane 616. The observer 214 will perceive the fourth world side image 610 traveling along or near the horizontal plane 616, and, therefore, the observer 214 will perceive content 614 in the world FOV 204. For example, as shown in Figure 6C,content 614 appears in the bottom right corner of the world FOV 204. However, it should be understood that content 614 may appear anywhere in the world FOV 204.

[0031] The present disclosure provides a system to project content to a user FOV and a world FOV simultaneously by controlling the angles light is reflected on the user side of a waveguide and the world side of a waveguide. Light leaving the waveguide on the world side is known as eye glow, and eye glow can be perceived by observers near the user. The present disclosure provides a system to use eye glow to create a world FOV, so that a user can project content towards observers on the world side of an augmented reality device.
