The authors show that prismatic adaptation can reduce tactile inattention in stroke patients with unilateral neglect. Four patients with visuospatial neglect and tactile extinction underwent 10-minute application of 20 degrees right-shifting prismatic lenses during pointing. This improved contralesional tactile perception in all patients, even for a task requiring no exploration or spatial moto...

Ideally, a tactile stimulator presents information through control of surface normal stress and surface shear stresses. Psy-chophysical experiments measured the eeect of shear stress information on the perception of static stimuli applied normal to the surface. Wax gratings in two diierent orientations and various spatial frequencies were used as stimuli. Elastic layers, representing the anti-a...

The potential of large tactile arrays to improve robot perception for safe operation in human-dominated environments and of high-resolution tactile arrays to enable humanlevel dexterous manipulation is well accepted. However, the increase in the number of tactile sensing elements introduces challenges including wiring complexity, power consumption, and data processing. To help address these cha...

Tactile experiences of textile materials are difficult to communicate and elicit. To interrogate this space we propose the tactile triangle, a framework to facilitate systematic analysis and comparison of tactile experiences. The three levels reflect different aspects of tactile experience and possible methods to capture them: physical properties, in which human senses or objective testing meas...

The experiment of the shape recognition for a tactile display is carried out and analysed in this paper. The purpose of this research is the development of a tactile stimulator array to represent the obstacle information for the visually impaired to walk safely. As a first step of this research, we investigate the characteristics of tactile stimuli and design the experimental system for the phy...

Filingeri D, Fournet D, Hodder S, Havenith G. Tactile cues significantly modulate the perception of sweat-induced skin wetness independently of the level of physical skin wetness. J Neurophysiol 113: 3462–3473, 2015. First published April 15, 2015; doi:10.1152/jn.00141.2015.—Humans sense the wetness of a wet surface through the somatosensory integration of thermal and tactile inputs generated b...

Tactile sensing is an important perception mode for robots, but the existing tactile technologies have multiple limitations. What kind of tactile information robots need, and how to use the information, remain open questions. We believe a soft sensor surface and high-resolution sensing of geometry should be important components of a competent tactile sensor. In this paper, we discuss the develo...

Perception of our environment is a multisensory experience; information from different sensory systems like the auditory, visual and tactile is constantly integrated. Complex tasks that require high temporal and spatial precision of multisensory integration put strong demands on the underlying networks but it is largely unknown how task experience shapes multisensory processing. Long-term music...
