Analysis of a Spectacle-Type Device for Rapid Visual Referencing

Abstract: This study investigates a reference form through which the user shifts his main eyesight view to the ancillary information presented by a monocular see-through head-mounted display (HMD) within a short time. The system requires only “glance” at ancillary information. Assuming that the HMD is applied for short-time referencing at any time, we hypothesize that the optimal position of the presented auxiliary information is the equilibrium point, where the referencing efficiency is traded against the complexity of the visual field. Besides presenting our proposed design, we experimentally verify this hypothesis in the current study. In the experiment, the optimal position of information presentation is evaluated from the time required to glance at HMD-presented information and from task performance, which relates to the complexity of the visual field. The optimal position was neither the periphery nor the center of the visual field but was shifted by 15° in the horizontal direction (external angle) from the center of the visual field.
