Sticky Light

Four students from the University of Tokyo have found a way to play Pong with a beam of light.

Sticky Light, a 3D tracking technology that lets you interact with a beam of light, batting it from one hand to another, is the work of Alvaro Cassinelli, Daito Manabe, Kuribara Yusaku and Stephane Perrin.

Once configured, the half-milliwatt spot of light can travel across vertical and horizontal surfaces, following paths in a printed maze or bounding off contoured objects, including human hands.

The technology could be used for games including a pinball and a “light-hockey” game in which players use their hands to bat the light, and scores will be displayed in real time.

The video below shows what the sticky light can do:
