Low-Fi VR Controller: Bringing 6DOF Interaction to Mobile VR

As virtual reality (VR) becomes an everyday technology, it is important to ensure it remains broadly accessible and affordable. Mobile VR is low-cost and accessible to everyone with a smartphone. However, it does not support a 6 degrees of freedom (6DOF) input device nor an effective way to select objects using the common techniques employed in commercial VR (i.e., ray- casting and virtual hand). Our Low-Fi VR Controller prototype provides a paper-based 6DOF input device for mobile VR. The controller's pose is tracked by the smartphone's camera and users can select objects by pointing the controller to direct a raycast or use the controller like a virtual hand. Selection indication can be performed using 300 ms dwell or a manual technique we refer to as Marker Selection comparable to click activation. This demo allows users to test the controller using both techniques and selection indication methods while performing ISO-9241-411 selection tasks. The top scores throughout the demo session will be displayed in leaderboards to promote friendly competition among attendees.
