Finally, A Hologram You Can Touch! Hiroyuki Shinoda & Co’s Touchable Holography at SIGGRAPH!

Hiroyuki Shinoda and his team of researchers from the University of Japan have developed a more fun(ctional) system of touchable holography. One that allows you to feel the holograms as they are projected! How do they do it?

Watch:

A curved mirror allows the hologram to float in space. Microjets of air provide the touch sensation, and a few hacked wiimotes offer hand tracking for true interactivity. Swoon. Want times ten.

It is interesting to note that as wonderful and complex as our epidermis (skin) is, it only allows for three “inputs” of sensation. Skin can feel fluctuations in temperature, pressure differences, and pain. That’s it. Any combination of those three inputs can give you the feeling of lazing in a hammock in a warm tropical lagoon, or marching across the dry arctic tundra, or being plunged into an icy stream.

You can fool the human body into thinking that it is experiencing these things rather easily, due to our skins easily-fooled nature. Fool the skin and fooling the mind is a snap.

That makes designing virtual systems for humans to interact with a bit simpler. As you can see, puffs of air can be interpreted as a balls bouncing on ones palm, or a small animal walking around.

As these systems increase in sophistication, we head into some seriously interesting times. What this could do for teaching! Especially autistic kids.
A learning curriculum based not on text and imagery but on physical sensation could be sensational. I’d love to learn like that.

Whoah: Space Origami!


From pinktentacle.com

“Researchers from the University of Tokyo have teamed up with members of the Japan Origami Airplane Association to develop a paper aircraft capable of surviving the flight from the International Space Station to the Earth’s surface.

The researchers are scheduled to begin testing the strength and heat resistance of an 8 centimeter (3.1 in) long prototype on January 17 in an ultra-high-speed wind tunnel at the University of Tokyo’s Okashiwa campus (Chiba prefecture). In the tests, the origami glider — which is shaped like the Space Shuttle and has been treated to withstand intense heat — will be subjected to wind speeds of Mach 7, or about 8,600 kilometers (5,300 miles) per hour.

A large spacecraft such as the Space Shuttle can reach speeds of up to Mach 20 (over 15,200 mph) when it re-enters the Earth’s atmosphere, and friction with the air heats the outer surface to extreme temperatures. The much lighter origami aircraft, which the researchers claim will come down more slowly, is not expected to burn up on re-entry.

No launch date has been set for the paper spaceplane, but Shinji Suzuki, an aerospace engineering professor at the University of Tokyo, is thinking ahead. “We hope the space station crew will write a message of peace on the plane before they launch it,” says Suzuki. “We don’t know where in the world the plane will land, but it would be nice to send a message to whoever finds it.”

Real or not, it made me smile.

Have a great day.
