future on display: technology you'll want to stroke - free digital signage

No matter what you expect from the latest computer technology, fur is unlikely to be one of them.
At the SIGGRAPH computer graphics and animation conference in Los Angeles this month, an unusual presentation was about the senses and used fiber to create a surface that felt furry.
Kosuke Nakajima of Osaka University in Japan and his colleagues say humans naturally tend to touch furry objects.
So, they say, we can interact with furry monitors without any instructions.
"The surface of the Fusa2 display is covered with fur made of fiber optic.
When users stand in front of the display, they start to touch the surface of the display without any suggestions and instructions, "said Yuichi Itoh, project manager at Osaka University.
When you stroke on the display, it changes the color and creates the stroke mark ".
"In order to detect the contact area, optical fiber-
"There are many infrared LEDs on the optical surface," Itoh explains . ".
Under the monitor, half of the fiber leads to the camera and the other half to the projector.
When a hand touches the fiber, the infrared radiation is reflected and spread along the fiber to the camera.
The image is fed into the computer, the computer calculates the trajectory of the hand, and lets the projector light up the colored light through other fibers to create the colored track.
Itoh believes that there are practical applications for screens that users intuitively want to tap.
Because people are naturally attracted to it, he says, it can work well with digital signage or robotic pets.
"If we were to create a bigger stadium, we could even build a football field consisting of a Fusa2 display.
This can show a lot of information, such as the offside line, the player's position and score. See more & colon;
