Abstract
Although the fundamentals of how humans perceive the world in 3D and the techniques used to implement 3D display devices have been discussed for over a century, humans still rely on 2D displays for interaction with almost every digital device. This implies that humans have been missing a significant amount of information when viewing content on conventional 2D displays.
This work presents the Holotab system, an interactive light field 3D display - an approach to make a glasses-free 3D light field display using a conventional 2D display and a lenticular sheet. The Holotab system uses 3D content encoded as streams of colour and depth information, then rendered using the Relief Mapping algorithm to ensure adequate performance for real-time applications.
An essential type of task in a virtual 3D environment is the ‘path traversing task’, which can be accomplished using a system where users leverage the kinematic chain to perform bimanual input. The users control the camera viewport using the Holotab, and to perform object manipulation using 3D printed tools in parallel. In this study, we found that the performance of our path traversing task depends on the width, the length, and the curvature of a path, regardless of the relative position between the Holotab and the tools.
