Gestures without libraries, toolkits or training: a $1 recognizer for user interface prototypes

Jacob O. Wobbrock, Andrew D. Wilson, Yang Li
2007 Proceedings of the 20th annual ACM symposium on User interface software and technology - UIST '07  
Although some user interface libraries and toolkits offer gesture recognizers, such infrastructure is often unavailable in design-oriented environments like Flash, scripting environments like JavaScript  ...  In addition, we found that medium-speed gestures, in which users balanced speed and accuracy, were recognized better than slow or fast gestures for all three recognizers.  ...  Prior work has attempted to provide gesture recognition for user interfaces through the use of libraries and toolkits [6, 8, 12, 17] .  ...

Opportunistic Interfaces for Augmented Reality: Transforming Everyday Objects into Tangible 6DoF Interfaces Using Ad hoc UI

Ruofei Du, Alex Olwal, Mathieu Le Goc, Shengzhi Wu, Danhang Tang, Yinda Zhang, Jun Zhang, David Joseph Tan, Federico Tombari, David Kim
2022 CHI Conference on Human Factors in Computing Systems Extended Abstracts  
Real-time environmental tracking has become a fundamental capability in modern mobile phones and AR/VR devices. However, it only allows user interfaces to be anchored at a static location.  ...  Although fiducial and natural-feature tracking overlays interfaces with specific visual features, they typically require developers to define the pattern before deployment. In this paper, we introduce  ...  As a proof-of-concept, we have developed Ad hoc UI (AhUI), a prototype toolkit to empower users to turn everyday objects into opportunistic interfaces on the fly.  ...
