Hexapods with Plane-Symmetric Self-Motions [PDF]
Robotics, 2018 A hexapod is a parallel manipulator where the platform is linked with the base by six legs, which are anchored via spherical joints. In general, such a mechanical device is rigid for fixed leg lengths, but, under particular conditions, it can perform a ...

Self-motion perception in the elderly [PDF]
Frontiers in Human Neuroscience, 2014 Self-motion through space generates a visual pattern called optic flow. It can be used to determine one's direction of self-motion (heading). Previous studies have already shown that this perceptual ability, which is of critical importance during everyday life, changes with age.

The perception of linear self-motion [PDF]
SPIE Proceedings, 2005 VR lends itself to the study of intersensory calibration in self-motion perception. However, proper calibration of visual and locomotor self-motion in VR is made complicated by the compression of perceived distance and by unfamiliar modes of locomotion.

Vestibular System and Self-Motion [PDF]
Frontiers in Cellular Neuroscience, 2018 Detection of the state of self-motion, such as the instantaneous heading direction, the traveled trajectory and traveled distance or time, is critical for efficient spatial navigation. Numerous psychophysical studies have indicated that the vestibular system, originating from the otolith and semicircular canals in our inner ears, provides robust ...

The Role of Self-Motion in Acrophobia Treatment [PDF]
CyberPsychology & Behavior, 2008 Acrophobia is a chronic, highly debilitating disorder preventing sufferers from engaging with high places. Its etiology is linked to the development of mobility during infancy. We evaluated the efficacy of various types of movement in the treatment of this disorder within a virtual reality (VR) environment.

Redundancy, Self-Motion, and Motor Control [PDF]
Neural Computation, 2009 Outside the laboratory, human movement typically involves redundant effector systems. How the nervous system selects among the task-equivalent solutions may provide insights into how movement is controlled. We propose a process model of movement generation that accounts for the kinematics of goal-directed pointing movements performed with a redundant ...

Modulation of recognition memory of emotional images by vertical vection
Frontiers in Psychology, 2016 Our previous research showed that vertical vection could modulate human mood. We further examined this possibility by using memory recognition task of positive, negative and neutral emotional images with high and low arousal levels.

Vision, 2022 Perceptual biases can be interpreted as adverse consequences of optimal processes which otherwise improve system performance. The review presented here focuses on the investigation of inaccuracies in multisensory perception by focusing on the perception ...

Sensors, 2021 Most algorithms for steering, obstacle avoidance, and moving object detection rely on accurate self-motion estimation, a problem animals solve in real time as they navigate through diverse environments.

Viewpoint-independent contextual cueing effect
Frontiers in Psychology, 2012 We usually perceive things in our surroundings as unchanged despite viewpoint changes caused by self-motion. The visual system therefore must have a function to process objects independently of viewpoint.
