SenseSurface: Stick Real Control Knobs On a Flat-Panel Virtual Display
Posted by Sean Fallon at 8:40 AM on July 16, 2008
Touchscreens are great, but for many of us nothing beats old fashioned tactile controls. That seems to be one of the reasons why Lyndsay Williams of Girton Labs is in the process of developing SenseSurface--a system that allows users to stick working knobs to on-screen virtual controls. Apparently, the magnetic knobs can be placed anywhere on an LCD because the movement is picked up by a "unique sensing surface" attached behind the screen. It seems fairly unnecessary, but I'm sure that there are practical applications for this for music and graphics fields--or anyone who is tired of smudging up a touchscreen. A video of SenseSurface in action is available after the break.
The patent shown is for an aircraft to be powered off the ground using a plasma technology. Subrata Roy, a University of Florida aerospace engineer, proposes the existing technique of passing a magnetic wave through a conducting fluid can produce a force strong enough to lift an aircraft off the ground. Granted, the example in the patent is only 15 cm, and attempts by others haven't gone particularly well. But with phrases like magnetohydrodynamics being thrown around, I keep flashing back to the space travel scene in Contact and getting excited. Subrata Roy must be a poet. [
We all know the hassle of digging into a pocket to twiddle the controls on our MP3 players, but until 
Those of you who are familiar with 
Straight out from Alice's Wonderland, this magnetic table and dinnerware are designed with four objectives: 1) store your plates, cups and cutlery, upside down, under the table, 2) arrange them neatly on top, 3) erase the data from any hard drive that comes near, and 4) cause head and eye injuries to kids and pets. Or drive them mad. And yet, we still want it. More pics after the jump.
So at first glance what we have here looks like a well designed four-port USB hub, with a handy top-placed port for convenient thumb-drive plugging. It's not 
This field has 1,301 florescent bulbs planted in it, and they're all glowing. They aren't plugged into anything, however; they're powered solely from the magnetic fields produced by the power lines above. It's all a large art project by Richard Box, and if you're really interested in it you can order a DVD of the whole thing from him. If you're cheaper and less interested, just peruse our gallery for the cool shots. 
The latest in relaxation technology comes to us from British company Hoverit in the form of a handmade acrylic lounger that can hover in mid air. As you might have guessed, the gravity defying aspects of the chair derive from repelling magnetic forces in both the bed and base. Hoverit also suggests that the magnetic forces can "help back, muscular problems and headaches" in addition to delivering a relaxing sensation akin to floating on air. More after the break.
Nokia is thinking about making its charging and headset ports magnetic, just like Apple's MagSafe ports on its laptops. Nokia users are well aware that the headset and charging ports on their phones are quite similar. The beauty of this idea is that there is a negative magnetic polarity on one of the ports and a positive polarity on the other, making it impossible to plug the wrong plug into the inappropriate jack. Great idea, and maybe a way to get to that "
