Strutting Hero, Sneaking Villain: Utilizing Body Motion Cues to Predict the Intentions of Others
Hanni Kiiski, Ludovic Hoyet, Andy T. Woods, Carol O’Sullivan, Fiona N. Newell
Article No.: 1
DOI: 10.1145/2791293

A better understanding of how intentions and traits are perceived from body movements is required for the design of more effective virtual characters that behave in a socially realistic manner. For this purpose, realistic body motion, captured...

Perception of Emotion and Personality through Full-Body Movement Qualities: A Sport Coach Case Study
Tom Giraud, Florian Focone, Virginie Demulier, Jean Claude Martin, Brice Isableu
Article No.: 2
DOI: 10.1145/2791294

Virtual sport coaches guide users through their physical activity and provide motivational support. Users’ motivation can rapidly decay if the movements of the virtual coach are too stereotyped. Kinematic patterns generated while performing...

The Effects of Visuomotor Calibration to the Perceived Space and Body, through Embodiment in Immersive Virtual Reality
Elena Kokkinara, Mel Slater, Joan López-Moliner
Article No.: 3
DOI: 10.1145/2818998

We easily adapt to changes in the environment that involve cross-sensory discrepancies (e.g., between vision and proprioception). Adaptation can lead to changes in motor commands so that the experienced sensory consequences are appropriate for the...

Gaze Transition Entropy
Krzysztof Krejtz, Andrew Duchowski, Tomasz Szmidt, Izabela Krejtz, Fernando González Perilli, Ana Pires, Anna Vilaro, Natalia Villalobos
Article No.: 4
DOI: 10.1145/2834121

This article details a two-step method of quantifying eye movement transitions between areas of interest (AOIs). First, individuals' gaze switching patterns, represented by fixated AOI sequences, are modeled as Markov chains. Second, Shannon's...

Compensating the Effect of Communication Delay in Client-Server--Based Shared Haptic Virtual Environments
Clemens Schuwerk, Xiao Xu, Rahul Chaudhari, Eckehard Steinbach
Article No.: 5
DOI: 10.1145/2835176

Shared haptic virtual environments can be realized using a client-server architecture. In this architecture, each client maintains a local copy of the virtual environment (VE). A centralized physics simulation running on a server calculates the...
