World-centered perception of 3D object motion during visually guided self-motion.
We investigated how human observers estimate an object's three-dimensional (3D) motion trajectory during visually guided self-motion. Observers performed a task in an immersive virtual reality system consisting of front, left, right, and floor screens of a room-sized cube. In one experiment, we found that the presence of an optic flow simulating forward self-motion in the background induces a w...
متن کاملNeural correlates of visual-motion perception as object- or self-motion.
Both self-motion and objects moving in our visual field generate visual motion by displacing images on the retina. Resolving this ambiguity may seem effortless but large-field visual-motion stimuli can yield perceptual rivalry between the real percept of object-motion and the illusory percept of self-motion (vection). We used functional magnetic resonance imaging to record brain activity in hum...
متن کاملNeural correlates of visually induced self-motion illusion in depth.
Optic-flow fields can induce the conscious illusion of self-motion in a stationary observer. Here we used functional magnetic resonance imaging to reveal the differential processing of self- and object-motion in the human brain. Subjects were presented a constantly expanding optic-flow stimulus, composed of disparate red-blue dots, viewed through red-blue glasses to generate a vivid percept of ...
متن کاملPerception of Self-motion and Presence in Auditory Virtual Environments
Apart from inducing a high sense of presence, creating a sensation of self-motion is often a key issue of many Virtual Reality applications. However, self-motion perception (vection) has been primarily investigated for visual stimuli. This study explored the possibility of inducing vection by realistic auditory stimuli. Furthermore, influence of various audio design parameters on auditoryinduce...
متن کاملRelative Visual Oscillation Can Facilitate Visually Induced Self-Motion Perception
Adding simulated viewpoint jitter or oscillation to displays enhances visually induced illusions of self-motion (vection). The cause of this enhancement is yet to be fully understood. Here, we conducted psychophysical experiments to investigate the effects of different types of simulated oscillation on vertical vection. Observers viewed horizontally oscillating and nonoscillating optic flow fie...
