Playsurface is a large-format touch table for entertainment as well as classroom math and science education. In a classroom, Playsurface can guide students to collide two real pucks together on the surface. If they hit "start" and slide the pucks, the path of the puck is tracked and displayed, plus at the collision point the vectors are superimposed to illustrate conservation of momentum. They can open up a control panel for the puck and change its coefficient of friction and see information about it, and by touching the path they can open up plots of the displacement vs time and overlay velocity vs time and acceleration vs time and drill down to the raw data.
The table augments the reality of a teaching lab experiment and allows students to explore the equipment, graphical control panels, real-time data being generated, and multimedia analysis of what is going on. It is a powerful and fun learning tool. Playsurface technology was demonstrated at CES, Las Vegas and featured on Make and Tech Crunch.
