The apparatus of claim 8, wherein the light guide comprises at least one touch sensor configured to recognize one or more gestures from one or more inputs detected from the one or more touch sensors. 10. The apparatus of claim 8, wherein the light guide further comprises at least one touch sensor included on the first side. 11. The apparatus of claim 8, wherein the at least part of the physical surroundings and at least part of the user interface are viewable concurrently using the light guide. 12. The apparatus of claim 8, wherein the processing device is further configured to execute applications and provide telephone functionality. 13. The apparatus of claim 12, wherein the housing is configured as a tablet or mobile phone. 14. The apparatus of claim 8, wherein the processing device is further configured to cause the light engine to output the user interface for display using the light guide along an image plane focused at infinity. 15. An apparatus comprising: a housing;a light guide supported by the housing having a first side that is viewable by a user, a second side opposing the first side, and switchable in-coupling optics; anda light engine disposed within the housing and optically coupled to the in-coupling optics of the light guide to output a user interface including an augmentation that is viewable concurrently with at least a portion of the physical environment through the light guide, wherein the light engine causes the light guide to project the user interface along an image plane focused at infinity, wherein a field of view of the user interface increases in reverse proportion to a distance between a user and the light guide, wherein a first amount of content of the user interface is in the field of view at a first distance between the user and the light guide, and a second amount of content of the user interface that is greater than the first amount of content is in the field of view at a second distance between the user and the light guide, wherein the first distance is greater than the second distance. 16. The apparatus of claim 15, wherein the second side of the light guide is disposed proximal to at least one lens to transmit an output of the light engine in out a back of the housing that is positioned opposite the first side of the light guide. 17. The apparatus of claim 15, wherein the switchable in-coupling optics are implemented at least partially using a switchable Bragg grating. 18. The apparatus of claim 1, further comprising a processing device disposed within the housing to cause the light guide to selectably control opacity of at least portions of the user interface such that an amount of the physical surroundings are viewable. 19.
