Abstract

The Wearable Scanning Laser Projector (WSLP) is a novel head-mounted display for augmented reality (AR). WSLP specializes the movement of a narrow display area to a wide real environmental area. AR systems commonly uses optical see-through head-mounted displays (HMD). With such HMDs, because the images are projected at a specific focal length, it is difficult to observe both the object and the corresponding images at the same time when they exist at different depths. In the WSLP, the center of the mirrors scanning the laser beam can be aligned conjugate to the center of the wearer's eye. As a result, the light spot of the beam is always observed at any depth. With the WSLP, information can be shared with nearby friends and colleagues who are not wearing similar devices.
