LaserTag Vest with Haptics and Optics

August 27, 2015

A LaserTag Vest Project. It makes the game fun with haptic and optic feedback. They system includes chest, belt and weapon. Each serves as an independent module, and engineered separately by different teams. Ours is Vest, which is the central hub for sensory data processing.
