XR Input Error Mediation for Hand-Based Input: Task and Context Influences a User's Preference Open
Many XR devices use bare-hand gestures to reduce the need for handheld controllers. Such gestures, however, lead to false positive and false negative recognition errors, which detract from the user experience. While mediation techniques en…

CrossCode: Multi-level Visualization of Program Execution Open
Program visualizations help to form useful mental models of how programs work, and to reason and debug code. But these visualizations exist at a fixed level of abstraction, e.g., line-by-line. In contrast, programmers switch between many l…

Iteratively Designing Gesture Vocabularies: A Survey and Analysis of Best Practices in the HCI Literature Open
Gestural interaction has evolved from a set of novel interaction techniques developed in research labs, to a dominant interaction modality used by millions of users everyday. Despite its widespread adoption, the design of appropriate gestu…

Sensing Hand Interactions with Everyday Objects by Profiling Wrist Topography Open
We demonstrate rich inferences about unaugmented everyday objects and hand object interactions by measuring minute skin surface deformations at the wrist using a sensing technique based on capacitance. The wristband prototype infers muscle…

Augmenting Mobile Phone Interaction with Face-Engaged Gestures Open
The movement of a user's face, easily detected by a smartphone's front camera, is an underexploited input modality for mobile interactions. We introduce three sets of face-engaged interaction techniques for augmenting the traditional mobil…

A Dataset of Naturally Occurring, Whole-Body Background Activity to Reduce Gesture Conflicts Open
In real settings, natural body movements can be erroneously recognized by whole-body input systems as explicit input actions. We call body activity not intended as input actions "background activity." We argue that understanding background…
