Synopsis Virtual Crowds by : Nuria Palechano
There are many applications of computer animation and simulation where it is necessary to model virtual crowds of autonomous agents. Some of these applications include site planning, education, entertainment, training, and human factors analysis for building evacuation. Other applications include simulations of scenarios where masses of people gather, flow, and disperse, such as transportation centers, sporting events, and concerts. Most crowd simulations include only basic locomotive behaviors possibly coupled with a few stochastic actions. Our goal in this survey is to establish a baseline of techniques and requirements for simulating large-scale virtual human populations. Sometimes, these populations might be mutually engaged in a common activity such as evacuation from a building or area; other times they may be going about their individual and personal agenda of work, play, leisure, travel, or spectator. Computational methods to model one set of requirements may not mesh well with good approaches to another. By including both crowd and individual goals and constraints into a comprehensive computational model, we expect to simulate the visual texture and contextual behaviors of groups of seemingly sentient beings.

Synopsis Virtual Crowds by : Mubbasir Kapadia
This volume presents novel computational models for representing digital humans and their interactions with other virtual characters and meaningful environments. In this context, we describe efficient algorithms to animate, control, and author human-like agents having their own set of unique capabilities, personalities, and desires. We begin with the lowest level of footstep determination to steer agents in collision-free paths. Steering choices are controlled by navigation in complex environments, including multi-domain planning with dynamically changing situations. Virtual agents are given perceptual capabilities analogous to those of real people, including sound perception, multi-sense attention, and understanding of environment semantics which affect their behavior choices. The roles and impacts of individual attributes, such as memory and personality are explored. The animation challenges of integrating a number of simultaneous behavior and movement demands on an agent are addressed through an open source software system. Finally, the creation of stories and narratives with groups of agents subject to planning and environmental constraints culminates the presentation.

Synopsis Modeling, Simulation and Visual Analysis of Crowds by : Saad Ali
Over the last several years there has been a growing interest in developing computational methodologies for modeling and analyzing movements and behaviors of ‘crowds' of people. This interest spans several scientific areas that includes Computer Vision, Computer Graphics, and Pedestrian Evacuation Dynamics. Despite the fact that these different scientific fields are trying to model the same physical entity (i.e. a crowd of people), research ideas have evolved independently. As a result each discipline has developed techniques and perspectives that are characteristically their own. The goal of this book is to provide the readers a comprehensive map towards the common goal of better analyzing and synthesizing the pedestrian movement in dense, heterogeneous crowds. The book is organized into different parts that consolidate various aspects of research towards this common goal, namely the modeling, simulation, and visual analysis of crowds. Through this book, readers will see the common ideas and vision as well as the different challenges and techniques, that will stimulate novel approaches to fully grasping “crowds."

Synopsis Crowd Design by : Florian Alexander Schmidt
Die digitale Revolution ist mit dem Versprechen verknüpft, die Selbstständigkeit des einzelnen Nutzers zu stärken. Der Aufstieg von kommerziellen Plattformen zur Koordination von Crowdarbeit stellt die Gültigkeit dieses Narrativs jedoch in Frage. In Crowd-Design analysiert Florian Alexander Schmidt die Entstehungsgeschichte, Funktionsweise und Rhetorik solcher Plattformen. Der Vergleich von historischen Crowd-Diskursen und Visionen der Online-Kollaboration bildet den Ausgangspunkt für eine kritische Betrachtung aktueller Ausprägungen von Crowdarbeit: Der Fokus der Studie liegt auf der Auslagerung von Designaufgaben unter Verwendung dieser Crowdsourcing-Plattformen. Grundlegenden Mechanismen, welche den Plattformbetreibern zur Motivation und Kontrolle der Crowds dienen, werden offengelegt.

Synopsis Crypto Crowds by : Matan Shapiro
Ownership of cryptocurrencies features contrasting forms of mobilization. On one hand, it denotes association with a global crowd of unrelated individual investors, which expands as it attracts more members. On the other hand, it includes participation in grassroots communities, which are generally more insular. Crypto Crowds demonstrates how this tension generates political, economic and moral realities in different cultural and geographical contexts. Pioneering in its approach to cryptocurrency trading, this volume will inspire scholars interested in the sociality of decentralized business models, boom-and-bust cycles on the blockchain, libertarian utopias and other postmodern crowding phenomena.
