Mechanisms of Tactile Information Transmission through Whisker Vibrations [PDF]

The Journal of Neuroscience, 2009
In their natural environment, rodents use their whiskers to locate and distinguish between objects of different textures and shapes. They do so by moving their whiskers actively as well as passively, through body and head movements. To determine the mechanisms by which surface coarseness is translated into neuronal discharges through passive whisker ...

Design and User Satisfaction of Interactive Maps for Visually Impaired People [PDF]

, 2012
Multimodal interactive maps are a solution for presenting spatial information to visually impaired people. In this paper, we present an interactive multimodal map prototype that is based on a tactile paper map, a multi-touch screen and audio output.

Influence of spaces between raised dot patterns and raised boundary lines on perceptibility of tactile guide map lines

Nihon Kikai Gakkai ronbunshu, 2016
Tactile guide maps are well-known information support tools for visually impaired people. In a tactile guide map, area information is expressed by use of raised dot patterns and raised boundary lines. Tactile guide map designers must place spaces between

Sensorimotor memories influence movement kinematics but not associated tactile processing

Scientific Reports, 2023
When interacting with objects, we often rely on visual information. However, vision is not always the most reliable sense for determining relevant object properties. For example, when the mass distribution of an object cannot be inferred visually, humans

More Than a Feeling: Learning to Grasp and Regrasp using Vision and Touch

, 2018
For humans, the process of grasping an object relies heavily on rich tactile feedback. Most recent robotic grasping work, however, has been based only on visual input, and thus cannot easily benefit from feedback after initiating contact.
