There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
---------------
Head-worn displays (HWDs) such as Google Glass are becoming more common. However, the optimal location for the display of such devices is an open question. Existing devices have displays located above, below, and in line with the primary position of gaze. In addition to vertical displacement, an HWD can be displaced laterally. In fact, several studies point to potential advantages of lateral displacement. Yet, little research has examined the effects of laterally displacing a HWD.
We evaluate lateral displacement of a monocular, small field of view (FOV) HWD across a representative set of activities for which a monocular, small FOV HWD may be used. The selected activities include situations where interacting with the HWD is the primary or sole task and situations where attention is shifted back and forth between the HWD and the real world. Specifically, we conduct three studies. The first two examine effects of lateral displacement on a long duration reading task. The third considers effects of lateral displacement on a modification of a common industrial task, order picking.
We suggest that monocular, small FOV displays should be mounted at lateral displacement angles of 20 degrees or less for sustained use. However, users may prefer offsets between 0 degrees and 10 degrees, with 10 degrees being more preferred because it keeps the display ``out of the way.''
