Depth Ray
Overview
The Depth Ray designed by Grossman and Balakrishnan 2006; Vanacken et al. 2007 is a 3D pointer enhancement which consists of a depth marker (In our implementation we've chosen this to be a 3D black cube) that is able to determine the closest object when multiple objects are intersected by the pointing vector. The user is able to determine the position of the depth marker based on their finger position on the HTC Vive touch-pad or (Oculus Rift joystick - not currently implemented Oculus support yet though).
Current implementation of Depth Ray as of 2/06/2018
