Peri-personal space as a prior in coupling visual and proprioceptive signals

It has been suggested that the integration of multiple body-related sources of information within the peri-personal space (PPS) scaffolds body ownership. However, a normative computational framework detailing the functional role of PPS is still …

Optimal Perceived Timing: Integrating Sensory Information with Dynamically Updated Expectations

The environment has a temporal structure, and knowing when a stimulus will appear translates into increased perceptual performance. Here we investigated how the human brain exploits temporal regularity in stimulus sequences for perception. We find …

Temporal Regularity of the Environment Drives Time Perception

It’s reasonable to assume that a regularly paced sequence should be perceived as regular, but here we show that perceived regularity depends on the context in which the sequence is embedded. We presented one group of participants with perceptually …

Computational aspects of softness perception

The duration of uncertain times: Audiovisual information about intervals is integrated in a statistically optimal fashion

Often multisensory information is integrated in a statistically optimal fashion where each sensory source is weighted according to its precision. This integration scheme isstatistically optimal because it theoretically results in unbiased perceptual …

Multisensory contributions to spatial perception

This chapter discusses the sensory systems that have been shown to contribute to spatial perception – vestibular, body-based, audition, and vision. We then present how spatial information is typically multisensory and estimates are integrated within …

Exploratory reach-to-grasp trajectories for uncertain object poses

This work addresses the problem of planning the reach-to-grasp trajectory for a robotic arm and hand, when there is uncertainty in the pose of the object being grasped. If the object is not in its expected location, then the robot may still gain …

Effects of visual-haptic asynchronies and loading-unloading movements on compliance perception

Spring compliance is perceived by combining the sensed force exerted by the spring with the displacement caused by the action (sensed through vision and proprioception). We investigated the effect of delay of visual and force information with respect …

Perceived compliance in a pinch

Handling a compliant object using a pinch grasp provides sensory information about deformation and resistive force from both index finger and thumb. In this paper, an object with rigid surfaces and composed of two compliant materials fixed on a …

The rubber hand illusion: Feeling of ownership and proprioceptive drift Do not go hand in hand

In the Rubber Hand Illusion, the feeling of ownership of a rubber hand displaced from a participant's real occluded hand is evoked by synchronously stroking both hands with paintbrushes. A change of perceived finger location towards the rubber hand …
