TickTockRay: Smartwatch Raycasting for Mobile HMDs

Abstract

We present TickTockRay, a smartwatch-based 3D pointing technique for smartphone-based immersive environments. Our work demonstrates that smartwatch-based raycasting may be a practical alternative to head-rotation-based pointing or specialized input devices. We release TickTockRay as an open-source plugin for Unity and provide an example of its use in a virtual reality clone of the Minecraft game.
