Disney Research's gloveless REVEL system adds virtual textures to physical objects

By - August 13, 2012 10 Pictures
Having long been successful with "talkies," Disney has developed technology that could allow the creation of "feelies." While designed more for touchscreens than the silver screen, the REVEL system developed at Disney Research uses reverse electrovibration to bring computerized control over the sense of touch, thereby allowing programmers to change the feel of real-world surfaces and objects without requiring users to wear special gloves or use force-feedback devices.

Tactile robot finger outperforms humans in identifying textures

By - June 18, 2012 4 Pictures
We’ve seen the development of a number of technologies that could be used to provide robots with a sense of touch, such as proximity and temperature sensing hexagonal plates and artificial skin constructed from semiconductor nanowires. However, perhaps none are as impressive as a tactile sensor developed by researchers at the University of California’s Viterbi School of Engineering. The group’s BioTac sensor was built to mimic a human fingertip and can outperform humans in identifying a wide range of materials, offering potential use for the technology in robotics and prostheses.

Touch typing for the iPad with the TouchFire screen-top keyboard

By - October 27, 2011 7 Pictures
For touch-typists like myself, tablets such as the iPad present a bit of a problem. I still need a little more tactile feedback to my fingertips than the virtual keyboard can offer, if I'm going to speed through my messages without making errors. When veteran computer designer Steve Isaac was left similarly wanting, he decided to get creative. Along with Seattle product designer and mechanical engineer Brad Melmon, Isaac has designed a transparent, flexible faux keyboard that lays on top of the iPad's virtual keyboard to give users the familiar feel of notebook-like raised keys.

Student-made tablet app may make dedicated Braille writers obsolete

By - October 11, 2011 1 Picture
Undergraduate student, Adam Duran, made excellent use of his time at Stanford University, where he attended a two-month summer course organized by the Army High-Performance Computing Research Center (AHPCRC). Together with his mentors, Adrian Lew and Sohan Dharmaraja, he created a potentially game changing application that should make the lives of visually impaired people both easier and less expensive. The application turns a tablet into a Braille writer and thus saves the blind from having to purchase a device that may cost up to ten times more than a tablet. Read More

Brain implant lets monkeys control virtual hand and feel virtual objects

By - October 6, 2011 1 Picture
In a development that could have huge implications for quadriplegics, paraplegics and those with prosthetic limbs, researchers from Duke University and the Ecole Polytechnic Federale de Lausanne (EPFL) have developed technology that has allowed monkeys to control a virtual arm and touch and feel virtual objects using only their brain activity. The researchers say it is the first-ever demonstration of a two-way interaction between a primate brain and a virtual body and could lead to robotic exoskeletons that not only that allows paralyzed patients to walk again, but to also feel the ground beneath them.

Disney’s Surround Haptics creates ‘virtual actuators’ to generate high-res tactile feedback

By - August 8, 2011 2 Pictures
In the quest for more immersive entertainment experiences, researchers at Disney Research, Pittsburgh (DRP) have developed a new tactile technology called Surround Haptics. Instead of just relying on sound and vision – and in the case of video games, vibrating controllers – the system uses a low-resolution grid of vibrating actuators to generate high-resolution, continuous, moving tactile strokes across a person’s skin. They claim the system is able to create smooth, continuous tactile motion, akin to the feeling of someone dragging a finger across someone’s skin, rather than the discrete tactile pulsations or buzzes commonly used in today’s haptic technology.

Glove with vibrating fingertip enhances user's sense of touch

By - August 4, 2011 3 Pictures
Studies have shown that with the right amount of white noise in the background, peoples’ sight, hearing, balance control and sense of touch improve. Utilizing stochastic resonance, which is the principle at work in white noise, researchers at the Georgia Institute of Technology have discovered that the sense of touch can also be improved by applying vibrations to a person’s finger. They have been testing a glove that incorporates a prototype fingertip-buzzing device, that could ultimately lead to products worn by people with nerve damage, or whose jobs require exceptional manual dexterity.

Surgical robot provides haptic feedback to users

By - October 9, 2010 2 Pictures
Robot-assisted surgery has a number of advantages over traditional surgery – it’s steadier, more precise, less invasive, plus the surgeon doesn’t even have to be in the same room (or continent) as the patient. One of its drawbacks, however, is the fact that surgeons can’t feel any of the resistance put up by the patients’ tissues – essentially, the controls provide no sense of touch. To address this problem, Linda van den Bedem from Eindhoven University of Technology (TU/e) has created a prototype surgical robot that does provide tactile feedback, and its name is Sofie... or Surgeon’s Operating Force-feedback Interface Eindhoven.
