Abstract

Augmented reality light guide display techniques are described. In one or more implementations, an apparatus includes a housing configured in a hand-held form factor, one or more sensors configured to detect a position and orientation of the housing in three dimensions in a physical environment of the housing, a light guide that is at least partially transparent and supported by the housing, a light engine that is optically coupled to the light guide, and one or more modules disposed within the housing and implemented at least partially in hardware. The one or more modules are configured to calculate a position and orientation of an augmentation and cause the light engine to output the augmentation for display using the light guide such that the augmentation is viewable concurrently with at least a portion of the physical environment through the light guide.

Claims

1. An apparatus comprising:

a housing configured in a hand-held form factor;

one or more sensors configured to detect a position and orientation of the housing in three dimensions in a physical environment of the housing;

a light guide that is at least partially transparent and supported by the housing;

a light engine that is optically coupled to the light guide; and

one or more modules disposed within the housing and implemented at least partially in hardware, the one or more modules configured to calculate a position and orientation of an augmentation and cause the light engine to output the augmentation for display using the light guide such that the augmentation is viewable concurrently with at least a portion of the physical environment through the light guide.

2. An apparatus as described in claim 1, wherein the augmentation is viewable in three dimensions by a user.

3. An apparatus as described in claim 1, wherein the housing is formed as part of a mobile phone or tablet and the one or more modules include wireless communication functionality.

4. An apparatus as described in claim 1, wherein the light guide is configured to display the augmentation along an image plane focused at infinity.

5. An apparatus as described in claim 1, wherein the light guide includes a layer that is selectable by the one or more modules to alter transparency of portions of the light guide such that a first said portion is transparent while a second said portion is not transparent.

6. An apparatus as described in claim 5, wherein the first said portion is used to view the portion of the physical environment and the second said portion is used to view the augmentation.

7. An apparatus as described in claim 1, wherein the one or more sensors are configured as one or more cameras, one or more depth sensing cameras, a gyroscope, one or more accelerometers, or a magnetometer.

8. A method comprising:

capturing one or more images of a user using one or more cameras of a handheld device that is held by a user;

calculating a location of the user'"'"'s pupils in three dimensional space from the captured one or more images by the handheld device; and

displaying an augmentation on a transparent display of the handheld device based on the calculated location of the user'"'"'s pupils that is viewable concurrently with at least a portion of a physical surroundings of the handheld device that is viewable through the transparent display.

9. A method as described in claim 8, wherein the transparent display is a light guide that is optically coupled to a light engine, the light engine configured to output the augmentation as specified by the one or more modules.

10. A method as described in claim 9, wherein the light engine does not output a display of the portion of the physical surroundings of the handheld device.

11. A method as described in claim 9, wherein the light guide is configured to display the augmentation along an image plane focused at infinity.

12. A method as described in claim 9, wherein the light guide includes a layer that is selectable to alter transparency of portions of the light guide such that a first said portion is transparent while a second said portion is not transparent.

13. A method as described in claim 12, wherein the first said portion is used to view the portion of the physical environment and the second said portion is used to view the augmentation.

14. A method as described in claim 8, wherein the handheld device is configured as a mobile phone or tablet.

15. A method as described in claim 8, wherein the transparent display includes a first side that is viewable by the user to see the augmentation and a second side opposing the first side, the second side including one or touch sensors configured to detect one or more gestures that are recognizable by the handheld device to initiation an operation of the handheld device.

16. A method as described in claim 8, wherein the transparent display is configured to display the augmentation to be viewable in three dimensions by the user.

17. An apparatus comprising:

a housing configured in a hand-held form factor;

one or more cameras positioned in the housing to track one or more eyes of a user;

a light guide that is at least partially transparent and supported by the housing;

a light engine that is optically coupled to the light guide; and

one or more modules disposed within the housing and implemented at least partially in hardware, the one or more modules configured to calculate a position of one or more pupils of the user in three-dimensional space and cause the light engine to output an augmentation for display based on the calculated position using the light guide such that the augmentation is viewable concurrently with at least a portion of the physical environment through the light guide.

18. An apparatus as described in claim 17, wherein the light guide includes a layer that is selectable to alter transparency of portions of the light guide such that a first said portion that corresponds to the portion of the physical environment is made transparent while a second said portion that corresponds to the augmentation is not made transparent.

19. An apparatus as described in claim 17, wherein the augmentation is viewable in three dimensions by the user.

20. An apparatus as described in claim 17, further comprising one or more sensors configured to detect a position and orientation of the housing in three dimensions in a physical environment of the housing, the one or more modules configured to calculate the augmentation based on the detected position and orientation of the housing in three dimensions along with the calculated position of one or more pupils of the user in three-dimensional space.
