Download or read book Virtual Crowds written by Nuria Palechano and published by Springer Nature. This book was released on 2022-05-31 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
Download or read book Crowd Simulation written by Daniel Thalmann and published by Springer Science & Business Media. This book was released on 2012-10-03 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research into the methods and techniques used in simulating crowds has developed extensively within the last few years, particularly in the areas of video games and film. Despite recent impressive results when simulating and rendering thousands of individuals, many challenges still exist in this area. The comparison of simulation with reality, the realistic appearance of virtual humans and their behavior, group structure and their motion, and collision avoidance are just some examples of these challenges. For most of the applications of crowds, it is now a requirement to have real-time simulations – which is an additional challenge, particularly when crowds are very large. Crowd Simulation analyses these challenges in depth and suggests many possible solutions. Daniel Thalmann and Soraia Musse share their experiences and expertise in the application of: · Population modeling · Virtual human animation · Behavioral models for crowds · The connection between virtual and real crowds · Path planning and navigation · Visual attention models · Geometric and populated semantic environments · Crowd rendering The second edition presents techniques and methods developed since the authors first covered the simulation of crowds in 2007. Crowd Simulation includes in-depth discussions on the techniques of path planning, including a new hybrid approach between navigation graphs and potential-based methods. The importance of gaze attention – individuals appearing conscious of their environment and of others – is introduced, and a free-of-collision method for crowds is also discussed.

Download or read book Modeling Simulation and Visual Analysis of Crowds written by Saad Ali and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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."

Download or read book Crowd Design written by Florian Alexander Schmidt and published by Birkhäuser. This book was released on 2017-07-24 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The digital revolution is interwoven with the promise to empower the user. Yet, the rise of centralized, commercial platforms for crowdsourced work questions the validity of this narrative. In Crowd-Design, Florian Alexander Schmidt analyses the workings and the rhetoric of crowdsourced work platforms by comparing the way they address the masses today with historic notions of the crowd. The utopian concepts of early online collaboration are taken as a vantage point from which to view and critique current and, at times, dystopian applications of crowdsourced work. The study is focused on the crowdsourcing of design tasks, but these specific applications are used to examine the design of the more general mechanisms employed by the platform providers to motivate and control the crowds. Crowd-Design is as much about the crowdsourcing of design as it is about the design of crowdsourcing.

Download or read book Crypto Crowds written by Matan Shapiro and published by Berghahn Books. This book was released on 2024-03-15 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Crowds and Party written by Jodi Dean and published by Verso Books. This book was released on 2016-02-09 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crowds and Party channels the energies of the riotous crowds who took to the streets in the past five years into an argument for the political party. Rejecting the emphasis on individuals and multitudes, Jodi Dean argues that we need to rethink the collective subject of politics. When crowds appear in spaces unauthorized by capital and the state-such as in the Occupy movement in New York, London and across the world-they create a gap of possibility. But too many on the Left remain stuck in this beautiful moment of promise-they argue for more of the same, further fragmenting issues and identities, rehearsing the last thirty years of left-wing defeat. In Crowds and Party, Dean argues that previous discussions of the party have missed its affective dimensions, the way it operates as a knot of unconscious processes and binds people together. Dean shows how we can see the party as an organization that can reinvigorate political practice.
Download or read book Crowds and Politics in North Africa written by Andrea Khalil and published by Routledge. This book was released on 2014-03-26 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes predominant crowd theory to task, questioning received ideas about ‘mob psychology’ that remain prevalent today. It is a synchronic study of crowds, crowd dynamics and the relationships of crowds to political power in Tunisia, Libya and Algeria (2011-2013) that has far reaching implications embedded in its thesis. One central theme of the book is gender, providing an in-depth look at women’s participation in the recent uprisings and crowds of 2011-2013 and the subsequent gender-related aspects of political transitions. The book also focuses on the social and political dynamics of tribalism and group belonging (‘asabiyya), including analysis and discussions with Libyan regional tribal chiefs, Libyan and Tunisian tribal members and citizens regarding their notions of tribal belonging. Crowd language and literature are also central to the book’s discussion of how crowds represent themselves, how we as observers represent crowds, and how crowds confront languages of authoritarianism and subjugation. Crowds and Politics in North Africa includes interviews with crowd participants and key civil society actors from Tunisia, Libya and Algeria. Among these, there are numerous interviews with Benghazi residents, activists and tribal leaders. One of the original case studies in the book is the crowd dynamics during and after the attack on the US consular installation in Benghazi, Libya. The book presents interviews and fieldwork within a literary and cultural theoretical context showing how crowds in the region resonate in forms of cultural resistance to authoritarianism. A valuable resource, this book will be of use to students and scholars with an interest in North African culture, society and politics more broadly.
Download or read book Emotion Personality and Cultural Aspects in Crowds written by Rodolfo Migon Favaretto and published by Springer Nature. This book was released on 2019-10-25 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practically-focused book presents a computational model for detection and analysis of pedestrian features in crowds from video sequences. The study of human behavior is a subject of great scientific interest and probably an inexhaustible source of research. The analysis of pedestrians and groups in crowds is relevant in several areas of application, such as security, entertainment, environmental and public spaces planning and social sciences. Cultural and personality aspects are attributes that can influence personal behavior and affect the group in which individuals belong. In this sense, we consider different ways of characterizing individuals and groups in crowds with respect to their relationship with the geometrical space and time. We discuss and describe an approach to extract and analyse, from the Computer Science point of view, emotions, personalities and cultural aspects from crowds and groups of pedestrians, using Computer Vision techniques. Extracting characteristics from real pedestrians and crowds, benefits other areas, such as: architecture and design (planning spaces to maximize pedestrian and group-environment fit); security and surveillance (design of evacuation plans considering characteristics of the crowds and detection of abnormal events); entertainment (more realistic crowds in movies and games reproducing characteristics from real pedestrians and crowds); social sciences (understanding of human behavior), among others. A big challenge in this area of research is the comparison with real life data. In this book, we successfully compared the results of the proposed approach with Psychology literature, where several studies aimed to analysis human behavior.

Download or read book Simulating Crowds in Egress Scenarios written by Vinícius J. Cassol and published by Springer. This book was released on 2017-12-08 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes, from a computer science viewpoint the software, methods of simulating and analysing crowds with a particular focus on the effects of panic in emergency situations. The power of modern technology impacts on modern life in multiple ways every day. A variety of scientific models and computational tools have been developed to improve human safety and comfort in built environments. In particular, understanding pedestrian behaviours during egress situations is of considerable importance in such contexts. Moreover, some places are built for large numbers of people (such as train stations and airports and high volume special activities such as sporting events). Simulating Crowds in Egress Scenarios discusses the use of computational crowd simulation to reproduce and evaluate egress performance in specific scenarios. Several case studies are included, evaluating the work and different analyses, and comparisons of simulation data versus data obtained from real-life experiments are given.
