Iterating with crowd
This thesis studies how novice designers iterate on their designs using the feedback received from a popular online forum Reddit. The goal was to understand the potential of online forums to serve the need for external feedback during the design process. The thesis also strives to understand the …

Crowd-powered systems
Crowd-powered systems combine computation with human intelligence, drawn from large groups of people connecting and coordinating online. These hybrid systems enable applications and experiences that neither crowds nor computation could support alone. Unfortunately, crowd work is error-prone and …

Virtual Crowd Interactive Applications
This thesis explores virtual crowd interactive applications: applications where large numbers of physically distributed people (tens of thousands) interact as a unified crowd. The purpose is to drive what social psychology identifies as the collective experience, a sense of: unity with many others; …

A Face in the Crowd
<p><strong>A face in a crowd </strong>is a series of<strong> </strong>ceramic busts portraying both famous and lesser known artists. I am doing portraits of artists because people tend to separate works of art from those who created them. I am trying to connect a face with a name. Most of the …

Crowd funding: between politics and antipolitics
Crowd funding platforms make projects financially viable through contributions from people in a way that apparently dismisses support from government or corporations. This realm is not precisely public but allows this community to sustain strong political claims. The tension in the divide between …

Extracting more wisdom from the crowd
… or predictions. We consider the wisdom-of-the-crowd problem of aggregating the judgments of multiple individuals on a single question, when no outside information about their competence is available. Many standard methods select the most popular answer, after correcting for variations in …

Crowd-sensing for smart city applications: towards solving crowd-sensing data challenges by introducing edge and cloud services
Crowd-sensing is the ability of a crowd to utilize sensors embedded in mobile devices to sense the surroundings and then send data to a centralized server or the cloud. With crowd-sensing, a wide range of applications have been empowered, such as smart city, healthcare and marketing, of which the …

A framework for video-driven crowd synthesis.
We present a framework for video-driven crowd synthesis. The proposed framework employs motion analysis techniques to extract inter-frame motion vectors from the exemplar crowd videos. Motion vectors collected over the duration of the video are processed to compute global motion paths. These paths …

Crowd-supervised training of spoken language systems
… that makes use of human computation to provide crowd-supervised training for spoken language systems. We explore human-in-the-loop algorithms that leverage the collective intelligence of crowds of non-expert individuals to provide valuable training data at a very low cost for actively deployed …

Real Time Crowd Visualization using the GPU
Crowd Simulation and Visualization are an important aspect of many applications such as Movies, Games and Virtual Reality simulations. The advantage with crowd rendering in movies is that the entire rendering process can be done off-line. And hence computational power is not much of an overhead. …

New Models for Crowd Dynamics and Control
… has been an increasing interest in modeling crowd and evacuation dynamics. Pedestrian models are based on macroscopic or microscopic behavior. In this work, we are interested in developing models that can be used for evacuation control strategies. Hence, we use macroscopic modeling approach, …

THE POWER OF CROWD IN THE BUSINESS WORLD
In this work, we focus on two attractive crowd-based business models, i.e., user-generated content creation and freight-matching long-haul trucking. First, as elaborated in CHAPTER 2, we consider a game theoretical modeling approach for understanding the operation of non-profit UGC platforms that …

Modeling Crowd Mobility and Communication in Wireless Networks
This dissertation presents contributions to the fields of mobility modeling, wireless sensor networks (WSNs) with mobile sinks, and opportunistic communication in theme parks. The two main directions of our contributions are human mobility models and strategies for the mobile sink positioning and …

Remote synchronous crowd support in challenging sports events
… To research this, we iteratively design online crowd interfaces, mobile applications, and devices that allow athletes to communicate with distributed spectators during sport activities. Athletes are able to broadcast their live performance to spectators through locative and biometric data …

Incentive mechanism design for mobile crowd sensing systems
… fast development and wide deployment of mobile crowd sensing (MCS) systems. Nowadays, applications of MCS systems have covered almost every aspect of people's everyday living and working, such as ambient environment monitoring, healthcare, floor plan reconstruction, smart transportation, indoor …

Evolving controllable emergent crowd behaviours with Neuro-Evolution
Crowd simulations have become increasingly popular in films over the past decade, appearing in large crowd shots of many big name block-buster films. An important requirement for crowd simulations in films is that they should be directable both at a high and low level, and be believable. As …

Modelling of crowd-induced vibrations in stadium terraces
Human-induced vibrations are increasingly becoming an issue of great concern in the design of civil engineering structures. In this research work, three major trends that contribute to the prevalence of human-induced vibrations in public structures were identified. While the focus has been mainly …

Mouse behavior recognition with the wisdom of crowd
In this thesis, we designed and implemented a crowdsourcing system to annotate mouse behaviors in videos; this involves the development of a novel clip-based video labeling tools, that is more efficient than traditional labeling tools in crowdsourcing platform, as well as the design of …

Collective causality : building solution architectures with a crowd
… assumption that by casting a wide net into the crowd, the likelihood of obtaining a desirable solution to a problem increases, due to the greater range of potential solutions that is obtained. This is typically implemented using a competitive format, where the best ideas are selected from a …
