Categorical perception of tactile distance [PDF]
Cognition, 2014 The tactile surface forms a continuous sheet covering the body. And yet, the perceived distance between two touches varies across stimulation sites. Perceived tactile distance is larger when stimuli cross over the wrist, compared to when both fall on either the hand or the forearm.

NeuroImage, 2023 Auditory perception can benefit from stimuli in non-auditory sensory modalities, as for example in lip-reading. Compared with such visual influences, tactile influences are still poorly understood. It has been shown that single tactile pulses can enhance

Tactile perception of thermal diffusivity [PDF]
Attention, Perception, & Psychophysics, 2009 The thermal diffusivity of an object is a parameter that controls the rate at which heat is extracted from the hand when it touches that object. It is an important feature for distinguishing materials by means of touch. In order to quantitatively describe the ability of human observers to discriminate between materials on the basis of heat extraction ...

Visuo-tactile heading perception
Journal of Neurophysiology, 2022 We investigated heading perception from visual-only (optic flow), tactile-only (tactile flow), or bimodal self-motion stimuli in different conditions varying in head and eye position. Overall, heading perception was body or world centered and non-Bayes optimal and revealed a centripetal bias.

PLoS ONE, 2022 Perception and action are essential in our day-to-day interactions with the environment. Despite the dual-stream theory of action and perception, it is now accepted that action and perception processes interact with each other.

Aging and the perception of tactile speed
Scientific Reports, 2022 AbstractEighteen younger and older adults (mean ages were 20.4 and 72.8 years, respectively) participated in a tactile speed matching task. On any given trial, the participants felt the surfaces of rotating standard and test wheels with their index fingertip and were required to adjust the test wheel until its speed appeared to match that of the ...

Scholarpedia, 2015 We do not just touch, we feel (Bajcsy, Proceedings of the IEEE 76(8): 966–1005, 1988). Our tactile sense is not merely a passive receiver of information, but actively selects and refines sensations according to our present goals and perceptions (Gibson, Psychological review, 69(6) 1962).

Tactile Perception of Rotational Sliding [PDF]
Second Joint EuroHaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (WHC'07), 2007 We present a new tactile display for rendering rotational friction at the fingertips. To inform the design and control of this device, we have conducted an initial set of perceptual experiments to investigate perceptual thresholds for rates of rotational slipping at the fingertips.

IEEE Access, 2022 To improve touchscreen accessibility, it has been proved efficient to integrate tactile feedback into touchscreen devices. Two typical techniques can be used to offer tactile feedback on smartphones, namely, mechanical vibration (MV) and ultrasonic ...

Spatial patterns in tactile perception: Is there a tactile field?
Acta Psychologica, 2011 Previous studies of tactile spatial perception focussed either on a single point of stimulation, on local patterns within a single skin region such as the fingertip, on tactile motion, or on active touch. It remains unclear whether we should speak of a tactile field, analogous to the visual field, and supporting spatial relations between stimulus ...
