Finally, a haptic display that might be worthwhile
Back in 2011, tactile displays were thought to be the next big thing in mobile computing, since you can't feel anything from glass-fronted smartphones. Tanvas, a startup out of Northwestern University, is looking to change all of that with its prototype haptic display. It's a system that can theoretically bolt onto any existing touchscreen, although some of its most exciting uses may not be on a smartphone (or tablet).
Researchers laugh in the face of flatness with new approaches to haptic displays (video)
If the future of haptic technology is your jam, then the symposium on User Interface Systems and Technology at the University of St. Andrews is the place to be this week. Teams from Disney Research and the University of Bristol will present two different approaches to adding 3D tactility to touch technology, and the results are pretty fascinating. While incorporating haptic feedback into displays isn't unheard of, adapting it to live content has been a challenge. At Disney, researchers developed an algorithm that can translate information culled from depth maps of virtual surfaces into dynamic tactile experiences. Through the magic of electrovibrations, the team was able to simulate changes in texture as a finger slid across a flat surface displaying both static imagery and live video. The group from Bristol opted for a different strategy; instead of vibrations produced by electricity, their UltraHaptics system relies on ultrasound speakers embedded behind a display used in conjunction with a Leap Motion controller. Basically, high-frequency sound waves produce an invisible field that creates a sensation of texture without the user having to touch the screen at all. Interest piqued? Check out videos of both systems in action after the break.
Disney's REVEL could turn the whole world into a tactile touchscreen (video)
Disney Research think it can go one better on Tactile and Haptic touch displays by using electrical fields to add sensation to nearly anything you can touch. Using Reverse Electrovibration, REVEL works by strapping an electrostatic signal generator to your body, so when you come into contact with an object on the same electrical plane, that low-level field can be altered to create friction. It's hoped that the technology could revolutionize touchscreens, add a whole new level of feeling to augmented reality and help blind people feel their way around. There's a video after the break, but be warned, it's light on the sort of cartoony hijinks you'd normally expect from the House of Mouse.
Keio University's Kinect-based Haptic VR system lets you roll your own face flat (video)
A research team at Keio University has built a fun haptic virtual reality system that enables you to manipulate pictures with a rolling pin. A vertically mounted Kinect takes a 3D image that is then displayed on the projection surface. Using the rolling pin, the image can be rolled over and flattened as if it was dough -- with a series of motor cranks inside the implement to replicate the necessary feedback so you can feel what it'd be like to iron out your own face. It's been designed as a modern-day update to the penny-squashing machines you found in theme parks, except with slightly more grotesqueness. You can watch the face-mashing in glorious color after the break.
