IEEE Transaction on Visualization and Computer Graphics (TVCG) vol.22, no.1, pp.21-30, Jan. 31, 2016 / IEEE Conference on Visual Analytics Science and Technology (VAST) Oct. 25-30, Chicago, IL, 2015. In print.

Pattern analysis of human motions, which is useful in many research areas, requires understanding and comparison of different styles of motion patterns. However, working with human motion tracking data to support such analysis poses great...

GestureAnalyzer: Visual Analytics for Pattern Analysis of  Mid-Air Hand Gestures

GestureAnalyzer: Visual Analytics for Pattern Analysis of Mid-Air Hand Gestures

Sujin Jang, Niklas Elmqvist, Karthik Ramani
Proceedings of the ACM Symposium on Spatial User Interaction, October 4-5, 2014, Honolulu, HI, USA

Understanding the intent behind human gestures is a critical problem in the design of gestural interactions. A common method to observe and understand how users express gestures is to use elicitation studies. However, these studies requires...

PuppetX: A Framework for Gestural Interactions With User Constructed Playthings

PuppetX: A Framework for Gestural Interactions With User Constructed Playthings

Saikat Gupta, Sujin Jang, and Karthik Ramani
Proceedings of the ACM Conference on Advanced Visual Interfaces, May 27-30, Como, Italy. pp. 73-80, 2014

We present PuppetX, a framework for both constructing playthings and playing with them using spatial body and hand gestures. This framework allows users to construct various playthings similar to puppets with modular components representing basic...
