Cuing Multiple-Targets for Visual Search in Virtual Reality

Visual search is a common task, especially given the high amount of spatial information we process visually. To aid in searching an environment for targets, various cues have been developed and implemented for augmented reality (AR) head-mounted displays (HMDs). A variety of designs have emerged from prior literature including the gaze line, 2D wedge, and 3D arrow, each with unique design characteristics. However, many of these designs are not evaluated beyond their initial design proposals. Results favored the gaze line cue for search time, accuracy, and reported mental effort, potentially highlighting the benefit of having both direction and location information embedded into the cue.
