Researchers at McGill University in Montreal, Canada have developed floor tiles that can simulate the look, sound and feel of snow, grass or pebbles underfoot. Such a tool could perhaps be used for augmented reality applications, tele-presence, training, rehabilitation or even as virtual foot controllers.

The modular "haptic" floor tiling system is made up of a deformable plate suspended on a platform. Between the plate and platform are sensors that detect forces from the user's foot. And the plate can give off vibrations that mimic the feeling of stepping on different materials. A top-down projection and speakers add visual and audio feedback.

Haptics - You feel me?

Technology Review - 3.3.10 (by Duncan Graham-Rowe)

Forget putting your phone on vibrate. A novel "high-definition" touch-feedback display can give a touch screen the feel of a textured surface. The technology was developed for mobile devices by the San Jose CA-based company Immersion, and is a step toward mimicking the feel of physical buttons on flat screens.

Simple haptic interfaces have been used in cell phones for years, to create silent alerts or provide limited tactile feedback when an onscreen button has been pressed. But such interfaces typically rely on elliptical vibration motors to create a shaking sensation, an approach that is slow and imprecise. Immersion believes this can be greatly improved by switching to a piezoelectric actuator.

Piezeoelectric materials produce mechanical stress in response to an applied voltage, or vice versa. They do this at great speed, which means piezoelectric actuators can respond quickly when a screen is being touched, says Steve Kingsley-Jones, Immersion's director of product management.

Soldier Surrogates - Sensory feedback for operators of military robots

Technology Review - 10/6/09 (by Kristina Grifantini)

A modified game controller will give military bomb-disposal experts remote touch.

iRobot, the company that makes military robots as well as the Roomba vacuuming bot, announced last Friday that it will receive funding for several endeavors from the Robotics Technology Consortium (RTC).

One project will see the company develop controllers that give remote robot operators sensory feedback. The US military currently uses iRobot's wheeled PackBot in Iraq and Afghanistan for tasks such as bomb disposal, detecting hazardous materials and carrying equipment.

The company says that adding force sensing to a PackBot arm could give operators the ability to "feel" the weight of an object or whether it is hard or soft, via the robot's arms.

Get those eyes back on the road! - Google Explores "Eyes-Free" Phones

Technology Review - June 2, 2009, by Kate Greene

An adaptive interface with tactile and audio feedback could make it easier to ignore a small screen.

The screens on many mobile phones can leave a user feeling distinctly vision impaired, especially if her attention is divided between tapping virtual buttons and walking or driving. Fortunately, engineers at Google are experimenting with interfaces for Android-powered mobile phones that require no visual attention at all. At Google I/O, the company's annual developer conference held in San Francisco last week, T.V. Raman, a research scientist at Google, demonstrated an adaptive, circular interface for phones that provides audio and tactile feedback.

One problem with most graphical user interfaces, says Raman, is that the buttons are in a fixed location, which is inconvenient if you can't feel them. To address this problem, his interface appears as soon as a finger touches the screen, so that it is centered on this initial touch.

"We are building a user interface that goes over and beyond the screen," says Raman. Often, eyes-free interfaces are employed for blind users, but Raman, who himself is blind, assures that these interfaces have much broader implications. "This is not just about the blind user," he says. "This is about how to use these devices if you're not in a position to look at the machine."

A soft touch - Touch Screens with Pop-up Buttons

Technology Review - April 28, 2009, by Kate Greene

Future touch screens may need to supply tactile feedback.

Touch-screen technology has become wildly popular, thanks to smart phones designed for nimble fingers. But most touch screens have a major drawback: you need to keep a close eye on the screen as you tap, to make sure that you hit the right virtual buttons. As touch screens become more popular in other contexts, such as in-car navigation and entertainment systems, this lack of sensory feedback could become a dangerous distraction.

Now researchers at Carnegie Mellon University have developed buttons that pop out from a touch-screen surface. The design retains the dynamic display capabilities of a normal touch screen but can also produce tactile buttons for certain functions.

Graduate student Chris Harrison and computer-science professor Scott Hudson have built a handful of proof-of-concept displays with the morphing buttons. The screens are covered in semitransparent latex, which sits on top of an acrylic plate with shaped holes and an air chamber connected to a pump. When the pump is off, the screen is flat; when it's switched on, the latex forms concave or convex features around the cutouts, depending on negative or positive pressure.

Bringing is together - The Best Computer Interfaces: Past, Present, and Future

Technology Review - April 6, 2009, by Duncan Graham-Rowe

Say goodbye to the mouse and hello to augmented reality, voice recognition, and geospatial tracking.

Computer scientists from around the world will gather in Boston this week at Computer-Human Interaction 2009 to discuss the latest developments in computer interfaces. To coincide with the event, we present a roundup of the coolest computer interfaces past, present, and future.

The granddaddy of all computer interfaces is the command line, which surfaced as a more effective way to control computers in the 1950s. Previously, commands had to be fed into a computer in batches, usually via a punch card or paper tape. Teletype machines, which were normally used for telegraph transmissions, were adapted as a way for users to change commands partway through a process, and receive feedback from a computer in near real time.

Video display units allowed command line information to be displayed more rapidly. The VT100, a video terminal released by Digital Equipment Corporation (DEC) in 1978, is still emulated by some modern operating systems as a way to display the command line.

Graphical user interfaces, which emerged commercially in the 1980s, made computers much easier for most people to use, but the command line still offers substantial power and flexibility for expert users.

Can you feel me? - Morphing gel display puts images at your fingertips

NewScientist - January 14 2009, by Jon Evans

A tactile display made from a watery gel that changes shape to show objects on its surface has been developed by German electrical engineers.

It uses a hydrogel, the type of material used to make soft contact lenses, which consists mainly of water bound up within a polymer. Some hydrogels can swell or shrink in response to changing conditions like temperature or acidity.

Andreas Richter and Georgi Paschew from the Technical University of Dresden turned to those abilities when trying to develop a new tactile display for blind people.
