Ghost Tiles
A head tilt controlled multiplayer mobile game for two players
Project Overview
Ghost Tiles transforms mobile gaming into a face to face social experience. Two players sit across from each other, both visible to the device's camera, and compete by controlling their respective characters through head movements alone. Each player navigates through obstacles in their dedicated lanes by tilting their head left or right. The game uses Apple's Vision framework to simultaneously track both faces in real time, detecting precise head angles and translating them into smooth character movements. This creates an engaging, physical gaming experience that encourages social interaction and friendly competition.
