Evaluation of the effect of a virtual avatar's representation on distance perception in immersive virtual environments

IEEE Conference on Virtual Reality and 3D User Interfaces, 2016
It is well known that distance estimation in immersive virtual reality environments suffers from compression when viewed from an egocentric perspective with a head mounted display.

The necessity of a perception-action approach to definite distance perception: Monocular distance perception to guide reaching.

Journal of Experimental Psychology: Human Perception and Performance, 1998
In this investigation of monocular perception of egocentric distance, the authors advocate the necessity of a perception-action approach because calibration is intrinsic to definite distance perception. A helmet-mounted camera and display were used to isolate optic flow generated by participants' head movements toward a target, and participants ...

Distance Perception in Insects

Current Directions in Psychological Science, 1992
motor agility enigmatic. Unlike vertebrates, insects have immobile eyes with fixed-focus op tics. The absence of eye movements implies that the range of an object cannot be inferred from the extent to which the directions of gaze of the two eyes must converge to view the object. The inability of an insect eye to change focus means that the dis tance to

Distance Perception in Autism and Typical Development

Perception, 2009
Children with autism and typically developing children walked blindfolded to a previously seen target (blindwalking task) and matched the frontal to the sagittal extent of a pattern formed by ropes on the ground (L-matching task). All participants were accurate in the blindwalking task. Children with autism were also very accurate in the matching task.

Egocentric distance perception in the Oculus Rift (DK2)

ACM Symposium on Applied Perception, 2015
Perceiving an accurate sense of absolute scale is important for the utility of virtual environments (VEs). Research shows that absolute egocentric distances are underestimated in VEs compared to the same judgments made in the real world, but there are ...

Cutaneous and kinaesthetic perception of traversed distance

2011 IEEE World Haptics Conference, 2011
Discrimination thresholds for tactually perceived traversed distance were measured in three conditions: cutaneous-only, kinaesthetic-only and combined information. The results were 25 mm (32 %) in the first and 11 mm (14 %) in the latter two conditions.

Distance Perception in Darkness

Science, 1964
Human subjects viewed round stimuli located equidistantly in the horizontal and vertical planes of vision under conditions where presumed cues to size were present and where they were systematically eliminated. Two experiments revealed a consistent tendency for the horizon object to be judged the closer. Cues introduced reduced the effect.

So near, so good: Does near-distance perception reduce interpersonal psychological distance?

, 2016
We conducted 2 experiments to explore whether or not the perception of interpersonal distance affects interpersonal psychological distance. Experiment 1 ( N = 60) involved a mixed design examination of the relationship between distance perception (near ...

Survey on depth perception in head mounted displays: distance estimation in virtual reality, augmented reality, and mixed reality

IET Image Processing, 2019
Depth perception is one of the important elements in virtual reality (VR). The perceived depth is influenced by the head mounted displays that inevitability decreases the virtual content's depth perception.

Speed Constancy and the Perception of Distance

Perception, 2008
The distance-calibration hypothesis states that retinal velocity is scaled by using distance cues, and judged velocity remains unchanged when distance is changed. The relational hypothesis states that judged velocity depends on retinal velocities, and is proportional to judged distance.
