Crowds of non-combatants play a large and increasingly recognized role in modern military operations, and often create substantial difficulties for the combatant forces involved. U. S. military actions in Mogadishu, Bosnia, and Iraq exemplify the significant effects crowds may have on military operations. However, in spite of their potential significance, realistic models of crowds are essentia...

Many crowd ideation systems seek to gather scores of ideas from people online. However, this often leads to many bad ideas and duplication. A dedicated facilitator who guides exploration of the solution space is a common and effective strategy for optimizing ideation in face-to-face brainstorming, but has not yet been explored in computer-supported crowd ideation. We introduce IdeaGens, a socia...

Crowd management is the human-traffic problem-solving for crowd control to manage the crowd activities by monitoring, simulating and designing model. This concept paper is to discuss on the crowd management and discover the major contributing factors that lead towards casualties during panic situation. Crowd management activity has a close relation with spatial management that gives a high impa...

conclusions experts are advised to focus on diverse sexual history dimensions, especially uncontrollable masturbation behaviors, that can predict sexual interests. although frotteurism is a rare psychiatric disorder, and although this case is atypical given the early childhood presentation of abnormal sexual behavior carried out secretly and not in a crowd, it is clear that frotteurism is the a...

We present an unsupervised approach to analyze crowd at various levels of granularity − individual, group and collective. We also propose a motion model to represent the collective motion of the crowd. The model captures the spatio-temporal interaction pattern of the crowd from the trajectory data captured over a time period. Furthermore, we also propose an effective group detection algorithm t...

With the increased use of crowd simulation in animation, specification of crowd motion can be very time consuming, requiring a lot of user input. To alleviate this cost, we wish to allow a user to interactively manipulate the many degrees of freedom in a crowd, whilst accounting for the limitation of low-dimensional signals from standard input devices. In this thesis we present two approaches f...

Objective. The existence of the home advantage in sport is well known. There is growing evidence that crowd noise plays a crucial part in this phenomenon. Consequently, a quantitative study was undertaken to examine influence of crowd noise upon refereeing decisions in association football (soccer). The association between years of experience and any imbalance in refereeing decisions was also a...

This paper presents a research agenda for crowd behavior research by drawing from the organizational control literature. It addresses the need for research into the organizational and social structures that guide user behavior and contributions in crowd-based platforms. Crowd behavior is situated within a conceptual framework of organizational control. This framework helps scholars more fully a...

The home advantage is one of the best established phenomena in sports (Courneya & Carron, 1992), and crowd noise has been suggested as one of its determinants (Nevill & Holder, 1999). However, the psychological processes that mediate crowd noise influence and its contribution to the home advantage are still unclear. We propose that crowd noise correlates with the criteria referees have to judge...

Crowd simulation models are currently lacking a commonly accepted validation method. In this paper, we propose level of presence achieved by a human in a virtual environment (VE) as a metric for virtual crowd behavior. Using experimental evidence from the presence literature and the results of a pilot experiment that we ran, we explore the egocentric features that a crowd simulation model shoul...
