A Tactile Automated Passive-Finger Stimulator (TAPS)
Although tactile spatial acuity tests are used in both neuroscience research and clinical assessment, few automated devices exist for delivering controlled spatially structured stimuli to the skin. Consequently, investigators often apply tactile stimuli manually. Manual stimulus application is time consuming, requires great care and concentration on the part of the investigator, and leaves many...

متن کاملStudy on Tactile Perception of Shape for Effective Tactile Display
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...
متن کاملThe Tactile Array Stimulator
A I3-element tactile array stimulator has been developed for research into the spatial-response properties of cortical neurons in the finger areas of the somatosensory cortex, the region of the cerebrum that receives and processes the somatic senses (touch, temperature, and pain). The tactile array consists of precision limited-motion, linear-displacement motors that are individually controlled...
متن کاملDissociated active and passive tactile shape recognition: a case study of pure tactile apraxia.
Disorders of tactile object recognition (TOR) may result from primary motor or sensory deficits or higher cognitive impairment of tactile shape representations or semantic memory. Studies with healthy participants suggest the existence of exploratory motor procedures directly linked to the extraction of specific properties of objects. A pure deficit of these procedures without concomitant gnost...
