Arc-Type and Tilt-Type: Pen-based Immersive Text Input for Room-Scale VR

ABSTRACT As immersive, room-scale virtual and augmented reality become more utilized in productive workflows, the need for fast, equally-immersive text input grows. Traditional keyboard interaction in these room-scale environments is limiting because of its predominantly-seated usage and the necessity for visual indicators of the hands and keys potentially breaking immersion. Pen-based VR/AR interaction presents an alternative immersive text input modality with high throughput. In this paper, we present two novel interfaces designed for a pen-shaped stylus that do not require the positioning of the controller within a region of space, but rather detect input from rotation and on-board buttons. Initial results show that compared with Controller Pointing text entry techniques, Tilt-Type was slower but produced fewer errors and was less physically demanding. Additional studies are needed to validate the results.
