Evaluating perceived trust from procedurally animated gaze

Aline Normoyle, +5 more
TL;DR: It is found that viewers can distinguish between high and low trust animations, that viewers associate the gaze differences specifically with trust and not with an unrelated attitude (aggression), and that the effect can hold for different facial expressions and scene contexts, even when viewed by participants for a short clip length.
Journal ArticleDOI

Evaluating and Optimizing Evacuation Plans for Crowd Egress

Vinicius J. Cassol, +8 more
- 01 Jan 2017 - 
TL;DR: The proposed framework can identify optimal evacuation plans using decision points, which control the ratio of agents that select a particular route at a specific spatial location based on a quantitatively validated metric for evacuation performance.
Journal ArticleDOI

Towards a quantitative approach for comparing crowds

Soraia Raupp Musse, +2 more
- 01 Feb 2012 - 
TL;DR: A new model to quantitatively compare global flow characteristics of two crowds is proposed that contains information on the local velocity of each spatial position, and the comparison is made using histogram distances.
Journal ArticleDOI

Detection of Global and Local Motion Changes in Human Crowds

Igor Rodrigues de Almeida, +4 more
- 01 Mar 2017 - 
TL;DR: A computer vision method is proposed to identify motion pattern changes in human crowds that can be related to an unusual event, and can identify global changes, by evaluating 2D motion histograms in time, and also local effects, by identifying clusters that present similar spatial locations and velocity vectors.

From their environment to their behavior: a procedural approach to model groups of virtual agents

Rafael Hocevar, +5 more
TL;DR: This work presents a model to simulate coherent group behaviors based on procedural modeling and semantic environments, present in the background of games or movies generated with few/without user intervention.
