spong, short for space pong is an interactive game our team created in 1 week for the building virtual worlds class. building off the basic concept of the classic game pong the team created a projection mapped play area with step on controllers on each side. as the guest steps on a block it lights up and activates a digital block in the game to try and block the incoming ball. Personally I designed, engineered, and fabricated the step on controllers. the interface we used to connect them to the game engine was Makey makey. the biggest challenge was simply there not being enough time to get in the parts we wanted so we adapted and made our own switches out of flat stock aluminum and rubber spacers. the contact is closed when the guest steps on the Plexiglass top compressing the rubber spacer which makes the top aluminum plate contact a screw coming out of the bottom aluminum plate.
