Influence of auditory cues on the visually-induced self-motion illusion (circular vection) in virtual reality. (scirp.org)
Stereoscopic depth cues provide information about distances of objects in near space as a function of their relative horizontal positions in the visual field. (britannica.com)
Researchers at MAKinteract Lab say the controller works as they determined the differences in how objects glide across skin or slip in one's hand and have paired this information with visual cues from the user, WALA reported . (foxbusiness.com)
They are able to replicate the slippage with the controller after they tested how the 'haptic realism of motion and thickness is perceived with varying visual cues in VR. (foxbusiness.com)
There is a gap in understanding how a temporal lag between visual and vestibular motion cues affects visual-vestibular weighting during self-motion perception. (mit.edu)
The present study examined modulation of event-related spectral power during a heading judgment task in which participants attended to either visual (optic flow) or physical (inertial cues stimulating the vestibular, proprioceptive and somatosensory systems) motion cues from a motion simulator mounted on a MOOG Stewart Platform. (mit.edu)
The temporal lag between the onset of visual and physical motion cues was manipulated to produce three lag conditions: simultaneous onset, visual before physical motion onset, and physical before visual motion onset. (mit.edu)
First, we demonstrated that when the attended motion cue was presented before an ignored cue, the power of beta associated with the attended modality was greater than when visual-vestibular cues were presented simultaneously or when the ignored cue was presented first. (mit.edu)
Second, we tested whether the power of feature-binding gamma ERS (demonstrated in audiovisual and visual-tactile integration studies) increased when the visual-vestibular cues were presented simultaneously versus with temporal asynchrony. (mit.edu)
We did not observe an increase in gamma ERS when cues were presented simultaneously, suggesting that electrophysiological markers of visual-vestibular binding differ from markers of audiovisual and visual-tactile integration. (mit.edu)

(jneurosci.org)

While the question of how the visual system detects and senses motion energies at different spatial and temporal frequencies has been fairly well studied, it is unclear how the visual system integrates this information to form coherent percepts of object motion. (jneurosci.org)

The medial temporal (MT) area receives direct input from V1 and is considered the first extrastriate area that integrates visual motion information ( Zeki, 1974 ). (jneurosci.org)
For example, if the light or sound emitted by a perceived event is scrambled, compressed or stretched en route to the perceiver, the duration of T (and even the temporal ordering of its parts) will be affected, and the resulting experience will probably misrepresent the temporal properties of the perceived event to a significant degree. (stanford.edu)
