Tactile perception of ultrasound

The Journal of the Acoustical Society of America, 1995
In this investigation, acoustic radiation force was used as a stimulus to determine the threshold for tactile perception in the human finger and upper forearm as a function of frequency and pulse duration. Initially, a small (1.8-cm2) acoustically reflecting disk was affixed to the anatomical exposure site to maximize the delivered radiation force ...

Tactile sensing utilizing human tactile perception

2011 IEEE World Haptics Conference, 2011
Human tactile perception incorporates two important characteristics - self-reference and bidirectionality. Self-reference is an important factor when evaluating tactile sensations. Bidirectionality contributes to sensing capability enhancement. In this paper, a tactile sensor including self-reference and bidirectionality is presented.

Anisotropy in tactile time perception [PDF]

Cortex, 2020
Spatial distortions in touch have been investigated since the 19th century. For example, two touches applied to the hand dorsum feel farther apart when aligned with the mediolateral axis (i.e., across the hand) than when aligned with the proximodistal axis (along the hand).

The Development of Tactile Perception

2017
Touch is the first of our senses to develop, providing us with the sensory scaffold on which we come to perceive our own bodies and our sense of self. Touch also provides us with direct access to the external world of physical objects, via haptic exploration.

Autism: tactile perception and emotion

Journal of Intellectual Disability Research, 2007
AbstractBackground  For many years, and especially since Waynbaum and Wallon, psychology and psychopathology have dealt with cognitive perception, but have had little to do with the affective qualities of perception. Our aim was to study the influence of the sensory environment on people with autism.Method  Several experiments were carried out using ...

Tactile Pattern Perception

Perception, 1981
Because efforts to use the cutaneous sense for conveying speech and visual information have met with only partial success, it would be useful to understand better the pattern-sensing capabilities of touch. This paper is an account of the sensory and perceptual factors known or hypothesized to limit the tactile perception of simple two-dimensional ...

The tactile perception of stimulus orientation

Somatosensory & Motor Research, 2008
Studies of the visual system suggest that, at an early stage of form processing, a stimulus is represented as a set of contours and that a critical feature of these local contours is their orientation. Here, we characterize the ability of human observers to identify or discriminate the orientation of bars and edges presented to the distal fingerpad ...

Neutral networks for tactile perception

Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003
The real-time solution to a basic inverse problem of tactile perception is investigated. Regularized solutions of this problem are obtained by a neural-analog network. Favorable setting times and noise immunity are observed in simulations and breadboard level experiments. >

Tactile Perception of Digital Images

2017
This paper introduces a prototype system of the tactile perception of digital images. The prototype system is comprised of several models, which include automatic image segmentation, texture shape recovery, multi-points interaction, real-time image deformation, and texture tactile rendering. For a common digit image, the prototype system in some extent
