1. A device comprising:
- a projector;
a keypad comprising at least first and second keys disposed on a portion of the keypad;
a waveguide comprising an image portion having a first surface forming a first boundary and a second surface forming a second boundary, the first and second surfaces of the waveguide image portion converging along the projection path from the projector, wherein the first key has a key surface facing a first region of the waveguide image portion, and the second key has a key surface facing a second region of the waveguide image portion, and wherein the first and second surfaces of the waveguide image portion are configured to direct first rays of electromagnetic radiation emitted from the projector onto the key surface of the first key at the first region of the waveguide image portion, and the first and second surfaces of the waveguide image portion are configured to direct second rays of electromagnetic radiation emitted from the projector by internal reflection therebetween through the first region of the waveguide image portion and onto the key surface of the second key at the second region of the image portion;
a projection controller, configured to receive instructions from a computing device and to provide the first rays of electromagnetic radiation via the projector onto the first key to form a first display image thereon, and provide the second rays of electromagnetic radiation via the projector onto the second key to form a second display image thereon, wherein the first and second display images are indicative of a first set of input controls when the computing device is in a first operating context, and a second set of input controls when the computing device is in a second operating context; and
an imaging sensor, configured to optically detect physical contacts between an object and the first and second keys.

Abstract
A dynamic projected user interface device is disclosed, that includes a projector, a projection controller, and an imaging sensor. The projection controller is configured to receive instructions from a computing device, and to provide display images via the projector onto display surfaces. The display images are indicative of a first set of input controls when the computing device is in a first operating context, and a second set of input controls when the computing device is in a second operating context. The imaging sensor is configured to optically detect physical contacts with the one or more display surfaces.

14. A device comprising:
-
a keypad, comprising one or more displaceable keys each being movable between a first, non-depressed position and a second, depressed position; an imaging sensor configured for entering input to a computing system; a substantially flat, tapered waveguide disposed along a path between the keypad and the imaging sensor, the imaging sensor being configured to detect physical displacement of each key of the one or more keys from the first, non-depressed position by imaging, through the waveguide, at least a portion of the key to determine a spatial position of the key; and a projector operatively connected to an output interface of the computing system, the projector being configured for dynamically generating images as a function of output from the computing system, and projecting the dynamically generated images through the waveguide and onto the one or more keys. - View Dependent Claims (15, 16, 17)
