Squiggle: Multimodal Lasso Selection in the Real World

Smart glasses devices are emerging with egocentric cameras and gaze tracking, raising the possibility of new interaction techniques that enable users to reference real-world objects they wish to digitally interact with. However, many of these devices lack a display, making precise object referencing difficult due to t…

Authoring LLM-Based Assistance for Real-World Contexts and Tasks

Advances in AI hold the possibility of assisting users with highly varied and individual needs, but the breadth of assistance that these systems could provide creates a challenge for how users specify their goals to the system. To support the authoring of AI assistance for real-world tasks, we propose the concept of C…

Body Language for VUIs: Exploring Gestures to Enhance Interactions with Voice User Interfaces

With the progress in Large Language Models (LLMs) and rapid development of wearable smart devices like smart glasses, there is a growing opportunity for users to interact with on-device virtual assistants through voice and gestures with ease. Although voice user interfaces (VUIs) have been widely studied, the potentia…

Exploring Visualizations for Precisely Guiding Bare Hand Gestures in Virtual Reality

Bare hand interaction in augmented or virtual reality (AR/VR) systems, while intuitive, often results in errors and frustration. However, existing methods, such as a static icon or a dynamic tutorial, can only inform simple and coarse hand gestures and lack corrective feedback. This paper explores various visualizatio…

FrameKit: A Tool for Authoring Adaptive UIs Using Keyframes

Adaptive user interfaces (AUIs) can improve user experience by adapting how information and functionality are presented in a user interface. However, the dynamic nature and potentially numerous variations of AUIs make them challenging to author. In this paper, we present a generalized framework for defining adaptati…

Detecting Input Recognition Errors and User Errors Using Gaze Dynamics in Virtual Reality

Gesture-based recognition systems are susceptible to input recognition errors and user errors, both of which negatively affect user experiences and can be frustrating to correct. Prior work has suggested that user gaze patterns following an input event could be used to detect input recognition errors and subsequently…
