Understanding, navigating, and performing goal-oriented actions in Mixed Reality (MR) environments is a challenging task and requires adequate information conveyance about the location of all virtual objects in a scene. Current Head-Mounted Displays (HMDs) have a limited field-of-view where augmented objects may be displayed. Furthermore, complex MR environments may be comprised of a large number of objects which can be distributed in the extended surrounding space of the user. This paper presents two novel techniques for visually guiding the attention of users towards out-of-view objects in HMD-based
the 3D Radar and the Mirror Ball. We evaluate our approaches against existing techniques during three different object collection scenarios, which simulate real-world exploratory and goal-oriented visual search tasks. To better understand how the different visualizations guide the attention of users, we analyzed the head rotation data for all techniques and introduce a novel method to evaluate and classify head rotation trajectories. Our findings provide supporting evidence that the type of visual guidance technique impacts the way users search for virtual objects in MR.

Partial or complete loss of vision in one half of the visual field(s) of one or both eyes. Subtypes include altitudinal hemianopsia, characterized by a visual defect above or below the horizontal meridian of the visual field. Homonymous hemianopsia refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field. Binasal hemianopsia consists of loss of vision in the nasal hemifields of both eyes. Bitemporal hemianopsia is the bilateral loss of vision in the temporal fields. Quadrantanopsia refers to loss of vision in one quarter of the visual field in one or both eyes.
The difference between two images on the retina when looking at a visual stimulus. This occurs since the two retinas do not have the same view of the stimulus because of the location of our eyes. Thus the left eye does not get exactly the same view as the right eye.
Repetitive visual hallucinations experienced mostly by elderly with diminished visual acuity or visual field loss, with awareness of the fictional nature of their hallucinations. It is not associated with delusions and other sensory hallucinations.
A view of the world and the individual's environment as comprehensible, manageable, and meaningful, claiming that the way people view their life has a positive influence on their health.
A subjective visual sensation with the eyes closed and in the absence of light. Phosphenes can be spontaneous, or induced by chemical, electrical, or mechanical (pressure) stimuli which cause the visual field to light up without optical inputs.
