The Blind Outperform Sighted People When Using Haptic Technology
2014-07-02 08:00:23

redOrbit Staff & Wire Reports - Your Universe Online New research in the burgeoning field of haptic technology at the University of California-Berkeley has discovered that people who are blind or visually impaired tend to outmaneuver their sighted counterparts – especially when they used both hands and multiple fingers to find their way around. The reason that blind subjects outperformed people with normal-range eyesight when it comes to using haptic (or tactile) technology is...

Where Does It Hurt?
2014-06-06 14:36:25

University College London A new UCL study defines for the first time how our ability to identify where it hurts, called "spatial acuity", varies across the body, being most sensitive at the forehead and fingertips. Using lasers to cause pain to 26 healthy volunteers without any touch, the researchers produced the first systematic map of how acuity for pain is distributed across the body. The work is published in the journal Annals of Neurology and was funded by the Wellcome Trust....

autism sense of touch
2014-05-22 07:53:46

April Flowers for redOrbit.com - Your Universe Online Our sense of touch can be simply an awareness, such as picking up a spoon, or it can evoke powerful emotions, such as when we receive a gentle caress. A new study from Liverpool John Moores University describes a system of slowly conducting nerves in the skin that respond to those gentle caresses. Researchers are using a variety of scientific techniques to characterize these nerves. The new findings, published in Neuron, reveal...

Juggling Holds Clues To How We Engage In Rhythmic Movements Like Running
2014-02-12 10:08:43

[ Watch the Video: Juggling For Prosthetics Research ] redOrbit Staff & Wire Reports - Your Universe Online The act of juggling is shedding new light on the role our vision and sense of touch have in helping control the way we engage in rhythmic movements such as running, researchers from John Hopkins University reported in the Journal of Neurophysiology. The study’s findings could someday aid in the treatment of people with neurological diseases, and help improve prosthetic...

Amputee Feels Sensory Rich Information In Real-time With Bionic Hand
2014-02-06 10:59:41

[ Watch The Video: Amputee Feels in Real-Time with Bionic Hand ] Hillary Sanctuary - Ecole Polytechnique Fédérale de Lausanne Dennis Aabo Sorensen is the first amputee in the world to feel sensory rich information -- in real-­time -- with a prosthetic hand wired to nerves in his upper arm; Sorensen could grasp objects intuitively and identify what he was touching while blindfolded. Nine years after an accident caused the loss of his left hand, Dennis Aabo Sørensen from Denmark...

Ultrasound Enhances Sensory Perception
2014-01-13 04:29:48

redOrbit Staff & Wire Reports - Your Universe Online Ultrasound, which is used by creatures such as bats and whales as a type of sensory guidance system, can also boost sensory perception in humans by modulating brain activity, according to new research appearing in Sunday’s online edition of Nature Neuroscience. In the paper, scientists from the Virginia Tech Carilion Research Institute report that low-intensity ultrasound focused on the transcranial region of the brain can...

Currently intraoperative monitoring using somatosensory evoked potentials has been widely recognized to prevent iatrogenic spinal cord injury. Previous studies only reported the monitoring effects of somatosensory evoked potentials after mechanical factors-caused spinal cord injury. However, spinal cord injury is not only triggered by mechanical factors, biochemical factors and vascular factors may cause spinal cord ischemia-reperfusion injury. It remains unclear whether spinal cord...

Disney Uses Haptic Feedback To Create Tactile Display
2013-10-07 19:27:20

Michael Harper for redOrbit.com – Your Universe Online Disney researchers in Pittsburgh have discovered a way to relay a tactile, 3D touch to a flat surfaces. In the same way a person can pass their finger over a 3D topographic map and feel the peaks and valleys against their skin, this new advancement could make the same interaction possible on touchscreen devices. By using haptic feedback and a clever algorithm, the researchers have developed a way to adjust the amount of friction...

A system that allows users to experience multi-point haptic feedback above an interactive surface without having to touch or hold any device will be unveiled this week [Friday 11 October] at one of the world's most important conferences for innovations in human-computer interfaces. Multi-touch surfaces offer easy interaction in public spaces, with people being able to walk-up and use them. However, people cannot feel what they have touched. A team from the University of Bristol's...

Touch Receptors In Skin Distinguish Textures Via Vibrations
2013-10-01 07:19:43

April Flowers for redOrbit.com - Your Universe Online Humans can distinguish between fine textures, such as silk or satin, through vibrations, a new study has found. These vibrations are picked up by two separate sets of nerve receptors in the skin and is relayed to the brain. Previously, studies have shown that course textures like Braille dot patterns are encoded by receptors that are densely packed into the primate fingertip. There is a correspondence between the spatial layout of...
