Striker Air Hockey
Guerrilla Nouveau has been hard at work on a new touchscreen technique. We made air hockey to demonstrate the possibilities of this low resolution touch screen technique, but couldn’t resist throwing in some extras.
Our first board, which had a lot of tracking problems when the board would flex.
*The touch grid is inexpensive (if time consuming) to make. The computer and pico-projector for displaying the gameplay cost significantly more.
What we had before were simple capacitive touch buttons. We could cut out tin foil, place it somewhere, and have a button. Our new capacitive touch grid technique lets us detect the presence of a palm on intersections spaced 3 inches horizontally or vertically, and can get more granular by measuring the proportional capacitance change on multiple activated intersections.
We can detect a palm press anywhere on the board. We can track your hand as it slides around. We have pretty good tracking, but we can improve it with software.
The idea of a touchscreen, or even a touch table, isn’t new. But a technique for turning any surface into a touchscreen for a fraction of the price of other technologies is. If accepted, we plan to come to GDC with how-to/tutorials/open-source software for our custom touchscreen technique.
Why Air Hockey?
Originally, for a school LAN party, we pulled this game of air hockey together to demonstrate how our grid works and can track hands swipes. But we’ve already added a ton of different add-ons and hope to add more.
-Goal Time Slow Motion
-Gravity wells (positive and negative)
-Hit the target mode
-Always Fast, Medium, or Slow pucks
-Puck that changes directions randomly
-Any Number of Pucks! (performance permitting)
-More Art, UI, and Sound Effects
-More modes and an easy switch menu
-Cleaner Hand Tracking
-Other games that use the touch grid, especially ones oriented to a multi-day conference with elements that change over days.
-Other Touchscreen Surfaces? (Wall? curved?)
