The Eye–Head Mover Spectrum: Modelling Individual and Population Head Movement Tendencies in Virtual Reality

People differ in how much they move their head versus their eyes when shifting gaze, yet such tendencies remain largely unexplored in HCI. We introduce head movement tendencies as a fundamental dimension of individual difference in VR and provide a quantitative account of their population-level distribution. Using a 3…

Adaptique: Multi-objective and Context-aware Online Adaptation of Selection Techniques in Virtual Reality

Selection is a fundamental task that is challenging in virtual reality due to issues such as distant and small targets, occlusion, and target-dense environments. Previous research has tackled these challenges through various selection techniques, but complicates selection and can be seen as tedious outside of their de…

MaRginalia: Enabling In-person Lecture Capturing and Note-taking Through Mixed Reality

Students often take digital notes during live lectures, but current methods can be slow when capturing information from lecture slides or the instructor's speech, and require them to focus on their devices, leading to distractions and missing important details. This paper explores supporting live lecture note-taking w…

Desk2Desk: Optimization-based Mixed Reality Workspace Integration for Remote Side-by-side Collaboration

Mixed Reality enables hybrid workspaces where physical and virtual monitors are adaptively created and moved to suit the current environment and needs. However, in shared settings, individual users’ workspaces are rarely aligned and can vary significantly in the number of monitors, available physical space, and worksp…

Snap, Pursuit and Gain: Virtual Reality Viewport Control by Gaze

Head-mounted displays let users explore virtual environments through a viewport that is coupled with head movement. In this work, we investigate gaze as an alternative modality for viewport control, enabling exploration of virtual worlds with less head movement. We designed three techniques that leverage gaze based o…

PhoneInVR: An Evaluation of Spatial Anchoring and Interaction Techniques for Smartphone Usage in Virtual Reality

When users wear a virtual reality (VR) headset, they lose access to their smartphone and accompanying apps. Past work has proposed smartphones as enhanced VR controllers, but little work has explored using existing smartphone apps and performing traditional smartphone interactions while in VR. In this paper, we consid…

Gaze on the Go: Effect of Spatial Reference Frame on Visual Target Acquisition During Physical Locomotion in Extended Reality

Spatial interaction relies on fast and accurate visual acquisition. In this work, we analyse how visual acquisition and tracking of targets presented in a head-mounted display is affected by the user moving linearly at walking and jogging paces. We study four reference frames in which targets can be presented: Head an…
