Obstacles Affect Perceptions of Egocentric Distances in Virtual Environments

Frontiers in Virtual Reality, 2021
Distance perception in humans can be affected by oculomotor and optical cues and a person’s action capability in a given environment, known as action-specific effects.

Action-Specific Perception & Performance on a Fitts's Law Task in Virtual Reality: The Role of Haptic Feedback [PDF]

, 2022
While user's perception & performance are predominantly examined independently in virtual reality, the Action-Specific Perception (ASP) theory postulates that the performance of an individual on a task modulates this individual's spatial & time perception pertinent to the task's components & procedures.

Investigation of the Uniformity of Gel Shrinkage by Imaging Tracer Particles Using X‐Ray Microtomography

Advanced Engineering Materials, EarlyView., 2023
A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

The Estimation of Physical Distances Between Oneself and a Social Robot: Am I as Far From the Robot as It is from Me?

Europe's Journal of Psychology, 2023
Research on the perception of interpersonal distance has shown the existence of an asymmetry effect which depends on the reference point of the estimation: the distance from oneself to others can be perceived as longer or shorter than the distance from ...

iSDF: Real-Time Neural Signed Distance Fields for Robot Perception [PDF]

Robotics: Science and Systems, 2022
We present iSDF, a continual learning system for real-time signed distance field (SDF) reconstruction. Given a stream of posed depth images from a moving camera, it trains a randomly initialised neural network to map input 3D coordinate to approximate ...

Distance and Size Perception in Astronauts during Long-Duration Spaceflight

Life, 2013
Exposure to microgravity during spaceflight is known to elicit orientation illusions, errors in sensory localization, postural imbalance, changes in vestibulo-spinal and vestibulo-ocular reflexes, and space motion sickness.

Importance of visual and non-visual information for perceived distance anisotropy [PDF]

Psihologija, 2009
The aim of this research was to verify whether perceived distance anisotropy exists even when visual information are available, that is, to examine interaction of non-visual (vestibular and proprioceptive) and visual information in depth perception.
