Scrolling in extended reality (XR) is currently performed using handheld controllers or vision-based arm-in-front gestures, which have the limitations of encumbering the user’s hands or requiring a specific arm posture, respectively. To address these limitations, we investigate freehand, posture-independent scrolling driven by wrist deflection. We propose two novel techniques: Wrist Joystick, which uses rate control, and Wrist Drag, which uses position control. In an empirical study of a rapid item acquisition task and a casual browsing task, both Wrist Drag and Wrist Joystick performed on par with a comparable state-of-the-art technique on one of the two tasks. Further, using a relaxed arm-at-side posture, participants retained their arm-in-front performance for both wrist techniques. Finally, we analyze behavioral and ergonomic data to provide design insights for wrist deflection scrolling. Our results demonstrate that wrist deflection provides a promising method for performant scrolling controls while offering additional benefits over existing XR interaction techniques.

There has been a great deal of research regarding the ways that people conceptualize and interact with places they call "home." This work has been extended to virtual reality primarily in the context of design tools. Here, we explore the idea of a hybrid virtual-physical home that uses virtual space to supplement an existing physical home. We identify variation in the spatial context of place attachment to homes. A user study (N = 25) revealed the expectations and needs these groups have for virtual home spaces, including security, familiarity, and community. We prototyped and playtested three virtual rooms, and identified design features that supported feelings of home. Finally, we present challenges to designing home-like VR environments that can shape future research in this area. As virtual reality grows increasingly accessible, these findings will inform the design of virtual spaces.
