Text Entry Performance and Situation Awareness of a Joint Optical See-Through Head-Mounted Display and Smartphone System
Optical see-through head-mounted displays (OST HMDs) are a popular output
medium for mobile Augmented Reality (AR) applications. To date, they lack
efficient text entry techniques. Smartphones are a major text entry medium in
mobile contexts but attentional demands can contribute to accidents while
typing on the go. Mobile multi-display ecologies, such as combined OST
HMD-smartphone systems, promise performance and situation awareness benefits
over single-device use. We study the joint performance of text entry on mobile
phones with text output on optical see-through head-mounted displays. A series
of five experiments with a total of 86 participants indicate that, as of today,
the challenges in such a joint interactive system outweigh the potential
benefits.Comment: To appear in IEEE Transactions on Visualization and Computer Graphics

Breaking the Screen: Interaction Across Touchscreen Boundaries in Virtual Reality for Mobile Knowledge Workers.
Virtual Reality (VR) has the potential to transform knowledge work. One
advantage of VR knowledge work is that it allows extending 2D displays into the
third dimension, enabling new operations, such as selecting overlapping objects
or displaying additional layers of information. On the other hand, mobile
knowledge workers often work on established mobile devices, such as tablets,
limiting interaction with those devices to a small input space. This challenge
of a constrained input space is intensified in situations when VR knowledge
work is situated in cramped environments, such as airplanes and touchdown
spaces.
In this paper, we investigate the feasibility of interacting jointly between
an immersive VR head-mounted display and a tablet within the context of
knowledge work. Specifically, we 1) design, implement and study how to interact
with information that reaches beyond a single physical touchscreen in VR; 2)
design and evaluate a set of interaction concepts; and 3) build example
applications and gather user feedback on those applications
