My name is Ang ‘Leon’ Li, or ‘李昂’ in Chinese character. I am currently a PhD candidate at the School of Information Technology and Electrical Engineering, University of Queensland in Australia. My supervisors are Dr. Maxime Cordeil, Dr. Jarrod Knibbe, Prof. Gianluca Demartini and A/Prof. Stephen Viller.

Prior to my PhD candidature at UQ, I completed my Bachelor’s Degree as the Dux in Computer Science Advanced from Monash University with a first-class honour. My honours thesis concerned the Visualisation and Analysis of Gesture Data in Immersive Environments. I had much pleasure of being supervised by Dr. Barrett Ens and Dr. Maxime Cordeil at Monash University’s Data Visualisation and Immersive Analytics Lab (Now the Embodied Visualisation Research Group).

My research interests revolve around the field of Human-Centred Interaction with a focus on Immersive Analytics. My current research topic explores data visualisation and interaction in augmented/virtual environments to support in-situ decision-making while the user is in motion.

This paper presents the design and evaluation of GestureExplorer, an Immersive Analytics tool that supports the interactive exploration, classification and sensemaking with large sets of 3D temporal gesture data. GestureExplorer features 3D skeletal and trajectory visualisations of gestures combined with abstract visualisations of clustered sets of gestures. By leveraging the large immersive space afforded by a Virtual Reality interface our tool allows free navigation and control of viewing perspective for users to gain a better understanding of gestures. We explored a selection of classification methods to provide an overview of the dataset that was linked to a detailed view of the data that showed different visualisation modalities. We evaluated GestureExplorer with two user studies and collected feedback from participants with diverse visualisation and analytics backgrounds. Our results demonstrated the promising capability of GestureExplorer for providing a useful and engaging experience in exploring and analysing gesture data.
