Alternation of Sound Location Induces Visual Motion Perception of a Static Object

Alternation of Sound Location Induces Visual Motion Perception of a Static Object

BACKGROUND Audition provides important cues with regard to stimulus motion although vision may provide the most salient information. It has been reported that a sound of fixed intensity tends to be judged as decreasing in intensity after adaptation to looming visual stimuli or as increasing in intensity after adaptation to receding visual stimuli. This audiovisual interaction in motion aftereff...

Perception of Curvature and Object Motion Via Contact Location Feedback

We describe a new tactile display for use in dexterous telemanipulation and virtual reality. Our system renders the changing location of a remote or virtual contact by moving a tactile element along the user’s fingertip. Mounted at the endpoint of a haptic mechanism, our thimble-sized device concurrently displays contact location and interaction forces. We believe such a design will enable more...

Static sound timing alters sensitivity to low-level visual motion.

Visual motion processing is essential to survival in a dynamic world and is probably the best-studied facet of visual perception. It has been recently discovered that the timing of brief static sounds can bias visual motion perception, an effect attributed to "temporal ventriloquism" whereby the timing of the sounds "captures" the timing of the visual events. To determine whether this cross-mod...

Visual and Non-Visual Contributions to the Perception of Object Motion during Self-Motion

Many locomotor tasks involve interactions with moving objects. When observer (i.e., self-)motion is accompanied by object motion, the optic flow field includes a component due to self-motion and a component due to object motion. For moving observers to perceive the movement of other objects relative to the stationary environment, the visual system could recover the object-motion component - tha...
