We present a platform for creating immersive 3D games including a new interface for navigating through virtual scenes. One innovative part of this application is a crowd simulation with an emergent behaviour of virtual characters. While the users has to move very quickly through a crowd of nearly two hundred virtual characters he is supported by a precise, fast operating, and unobtrusive naviga...

This paper presents a scalable approach to crowd simulation that can generate complex and varied simulations by using multiple types of individuals in a crowd. Efficiency is attained by using a situation-based approach where an individual agent adopts behaviors according to its situation, which corresponds to a subspace of the universe.

We present a new civilian crowd simulator for the Robocup Rescue Simulation that allows to represent large numbers of civilians and in which psychologically and socially plausible crowd behavior emerges. As a new challenge for the Rescue Simulation competition, the simulator also allows police agents to indirectly influence crowd behavior by temporarily blocking roads. The simulator can be used...

In this paper, we present a comparison between controlled laboratory experiments and crowd-sourcing techniques for gathering consumer terms. We discuss the difference between the data gathered from these techniques and how crowd-sourcing can be used to increase engagement and seek feedback from your customers via the internet or other digital methods. As a case study, we present a new set of un...

There are currently many trends in computer science, like Smart Cities, Internet of Things, and Wireless Sensor Networks. Many of these systems require or could dramatically benefit from having information about crowds. First of all, many of the systems are built to improve the life of people, and they require information about them to be able to know when to activate their functionality in ord...

Crowd sourcing provides a cheap and fast way to obtain speech transcriptions. The crowd size available for a task is inversely proportional to the skill requirements. Hence, there has been recent interest in studying the utility of mismatched crowd workers, who provide transcriptions even without knowing the source language. Nevertheless, these studies have required that the worker be capable o...

The change of crowd energy is a fundamental measurement for describing a crowd behavior. In this paper, we present a crowd abnormal detection method based on the change of energy-level distribution. The method can not only reduce the camera perspective effect, but also detect crowd abnormal behavior in time. Pixels in the image are treated as particles, and the optical flow method is adopted to...

Objective: This work proposes a novel approach to model the spatiotemporal distribution of crowd motions and detect anomalous events. Methods: We first learn the regions of interest (ROIs) which inform the behavioral patterns by trajectory analysis with Hierarchical Dirichlet Processes (HDP), so that the main trends of crowd motions can be modeled. Based on the ROIs, we then build a series of h...
