This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for displaying directional visual indicators external to a wearable device for navigation. In some aspects, a wearable device may receive navigation signals while the wearable device is in a navigation mode. The navigation signals may indicate a direction of travel. The wearable device may display a first directional visual indicator corresponding to the direction of travel. The first directional visual indicator may be displayed external to the wearable device indicating the direction of travel is a first direction. The first directional visual indicator may be a directional light or a directional projection displayed external to the wearable device in the direction of travel. If the direction of travel changes from the first direction to a second direction, the wearable device may display a second directional visual indicator indicating the direction of travel is the second direction.

Displaying directional visual indicators from a wearable device for navigation

A display processor of a display system may receive an image that includes a test pattern. An input checksum may be associated with the test pattern. Hardware units of the display processor may process the image. The display system may generate an output checksum based at least in part on the test pattern after processing of the image. The display system may detect a fault in the hardware units of the display processor based on determining a difference between the input checksum and the output checksum.
