A team of All Japan newsese scientists at Meiji University created the LightCloth, an interactive sheet that is made of fiber optic lines and that changes its color as soon as it is touched with a special pen.
“Although the fabric is so thin, it can emit light in full color. Each strand emits a different color. As well as making the interface light up, you can use this pen to change the color. On the fabric side, the system can detect what kind of signal is coming in, and from where,” Senior Assistant Professor Sunao Hashimoto explained, according to the media.
The threads can act both as outputs for computer-controlled light patterns and as inputs using the associated IR stylus.
“We are using a pen here, but you can also change the color through a laser pointer,” Hashimoto continued. “So, you could do things like changing the color of people on a stage from a distance. Because the fibers are woven in one direction, the information is one-dimensional. Next, we would like to make it two-dimensional.”
