Tactile Acuity Charts: A Reliable Measure of Spatial Acuity
For assessing tactile spatial resolution it has recently been recommended to use tactile acuity charts which follow the design principles of the Snellen letter charts for visual acuity and involve active touch. However, it is currently unknown whether acuity thresholds obtained with this newly developed psychophysical procedure are in accordance with established measures of tactile acuity that ...
متن کاملTactile Spatial Acuity from Childhood into Adulthood
Measurement of human tactile spatial acuity – the ability to perceive the fine spatial structure of surfaces contacting our fingertips – provides a valuable tool for probing both the peripheral and central nervous system. However, measures of tactile spatial acuity have long been plagued by a prodigious amount of variability present between individuals in their sense of touch. Previously propos...
متن کاملA Low Cost Tactor Suit for Vibrotactile Feedback
We constructed low cost tactors for vibrotactile feedback across the human arm for the purpose of providing a physical sensation surrogate for virtual objects. The tactors were built from readily available commercial parts, and provide low amplitude vibration for tactile feedback. The tactors are Velcro mounted on a custom suit designed to ensure localized sensations of each tactor. The suit is...
متن کاملVibrotactile Letter Reading Using a Low-Resolution Tactor Array
Vibrotactile displays have been studied for several decades in the context of sensory substitution. Recently, a number of vibrotactile displays have been developed to extend sensory modalities in virtual reality. Some of these target the whole body as the stimulation region, but existing systems are only designed for discrete stimulation points at specific parts of the body. However, since huma...
متن کاملPosteromedial parietal cortical activity and inputs predict tactile spatial acuity.
We used functional magnetic resonance imaging (fMRI) to investigate the neural circuitry underlying tactile spatial acuity at the human finger pad. Stimuli were linear, three-dot arrays, applied to the immobilized right index finger pad using a computer-controlled, MRI-compatible, pneumatic stimulator. Activity specific for spatial processing was isolated by contrasting discrimination of left-r...
