Recently a collaborative paper between De Montfort University, Coventry University and Masaryk University (HCI Lab) was published at the journal of Entertainment Computing, sponsored by Elsevier. The paper is entitled “Assessing the perceived realism of agent grouping dynamics for adaptation and simulation” and is focused on applications targeting human interaction. The paper presents a novel method using psychophysics to assess the perceived realism of behavioural features with respect to virtual crowds.
Focus is given to the grouping dynamics feature, whereby crowd composition in terms of group frequency and density is evaluated through thirty-six conditions based on crowd data captured from three pedestrianised real-world locations. The study, conducted with seventy-eight healthy participants, allowed for the calculation of perceptual thresholds, with configurations identified that appear most real to human viewers. Results suggest that viewers have more perceptual flexibility when group frequency and density are increased, rather than decreased.
