Understanding User Needs for Task Guidance Systems Through the Lens of Cooking

To design intuitive and effective context-aware task guidance systems, we must understand users’ thought processes and the obstacles they experience when they perform tasks. Though task guidance systems have proven beneficial in many domains for improving task performance and reducing user frustration, there is a lack…

Investigating Contextual Notifications to Drive Self-Monitoring in mHealth Apps for Weight Maintenance

Mobile health applications for weight maintenance offer self-monitoring as a tool to empower users to achieve health goals (e.g., losing weight); yet maintaining consistent self-monitoring over time proves challenging for users. These apps use push notifications to help increase users’ app engagement and reduce long-t…

"It Would Be Cool to Get Stampeded by Dinosaurs": Analyzing Children's Conceptual Model of AR Headsets Through Co-Design

Children are being presented with augmented reality (AR) in different contexts, such as education and gaming. However, little is known about how children conceptualize AR, especially AR headsets. Prior work has shown that children's interaction behaviors and expectations of technological devices can be quite different…

Exploring Virtual Agents for Augmented Reality

Prior work has shown that embodiment can benefit virtual agents, such as increasing rapport and conveying non-verbal information. However, it is unclear if users prefer an embodied to a speech-only agent for augmented reality (AR) headsets that are designed to assist users in completing real-world tasks. We conducted…

EASEL: Easy Automatic Segmentation Event Labeler

Video annotation is a vital part of research examining gestural and multimodal interaction as well as computer vision, machine learning, and interface design. However, annotation is a difficult, time-consuming task that requires high cognitive effort. Existing tools for labeling and annotation still require users to m…

Investigating Separation of Territories and Activity Roles in Children’s Collaboration around Tabletops

Prior work has shown that children exhibit negative collaborative behaviors, such as blocking others’ access to objects, when collaborating on interactive tabletop computers. We implemented previous design recommendations, namely separate physical territories and activity roles, which had been recommended to decrease…
