'Show It, Don't Just Say It': The Complementary Effects of Instruction Multimodality for Software Guidance

Designing adaptive tutoring systems for software learning presents challenges in determining appropriate instructional modalities. To inform the design of such systems, we conducted an observational study of ten human teacher-student pairs (N=20), where experienced design software users taught novices two new graphic…

Prompting an Embodied AI Agent: How Embodiment and Multimodal Signaling Affects Prompting Behaviour

Current voice agents wait for a user to complete their verbal instruction before responding; yet, this is misaligned with how humans engage in everyday conversational interaction, where interlocutors use multimodal signaling (e.g. nodding, grunting, or looking at referred to objects) to ensure conversational grounding…

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…

How People Prompt Generative AI to Create Interactive VR Scenes

Generative AI tools can provide people with the ability to create virtual environments and scenes with natural language prompts. Yet, \textit{how} people will formulate such prompts is unclear---particularly when they inhabit the environment that they are designing. For instance, it is likely that a person might say,…

Stargazer: An Interactive Camera Robot for Capturing How-To Videos Based on Subtle Instructor Cues

Live and pre-recorded video tutorials are an effective means for teaching physical skills such as cooking or prototyping electronics. A dedicated cameraperson following an instructor’s activities can improve production quality. However, instructors who do not have access to a cameraperson’s help often have to work wi…

Tourgether360: Collaborative Exploration of 360 Tour Videos using Pseudo-Spatial Navigation

Collaborative exploration of 360° videos with contemporary interfaces is challenging because collaborators do not have awareness of one another’s viewing activities. Tourgether360 enhances social exploration of 360° tour videos using a pseudo-spatial navigation technique that provides both an overhead “context” view o…

immersivePOV: Filming How-To Videos with a Head-Mounted 360° Action Camera

How-to videos are often shot using camera angles that may not be optimal for learning motor tasks, with a prevalent use of third-person perspective. We present \textit{immersivePOV}, an approach to film how-to videos from an immersive first-person perspective using a head-mounted 360° action camera. immersivePOV how-t…

ASTEROIDS: Exploring Swarms of Mini-Telepresence Robots for Physical Skill Demonstration

Online synchronous tutoring allows for immediate engagement between instructors and audiences over distance. However, tutoring physical skills remains challenging because current telepresence approaches may not allow for adequate spatial awareness, viewpoint control of the demonstration activities scattered across an…

Route Tapestries: Navigating 360 Virtual Tour Videos Using Slit-Scan Visualizations

An increasingly popular way of experiencing remote places is by viewing 360 virtual tour videos, which show the surrounding view while traveling through an environment. However, finding particular locations in these videos can be difficult because current interfaces rely on distorted frame previews for navigation. To…

HoloBoard: a Large-format Immersive Teaching Board based on Pseudo HoloGraphics

In this paper, we present HoloBoard, an interactive large-format pseduo-holographic display system for lecture based classes. With its unique properties of immersive visual display and transparent screen, we designed and implemented a rich set of novel interaction techniques like immersive presentation, role-play, and…
