Researchers at the University of Tokyo have developed AquaTop Display, a system that uses bath-salts enriched water to display and interact with the digital contents. Unlike some conventional touchscreens, this AquaTop display technology allows to operate the objects from all sides/directions in order to delete some photos by sinking them into the water .
Details about AquaTop display from Tokyo University:
“AquaTop display is a projection system that uses white water as a screen surface. This system allows the user’s limbs to freely move through, under and over the projection surface. Using the unique characteristics of fluid, we propose new interactions methods specific to the projection medium, water. Our system uses a depth camera to detect input on and over the water surface to allow for interactions such as protruding fingers out from under the water surface and scooping up the water with both hands. This type of interaction is not capable with current impenetrable, rigid body, flat surfaces. For example, by floating one’s limbs on the water surface, it is also possible to fuse one’s body with the displayed objects for further augmented interaction by ‘becoming one’ with the screen.”
So folks.! You can play swim pong! You could have 2 people in a swimming pool, 1 person on each side, both acting as paddles .. swim back and forth to bounce the ball! I think that’d be fun for you and you’d love the water based gaming.
