Deployment Planning for Location Recognition in the Smart-Condo™: Simulation, Empirical Studies and Sensor Placement Optimization [Download]
Title: Deployment Planning for Location Recognition in the Smart-Condo™: Simulation, Empirical Studies and Sensor Placement Optimization Creator: Vlasenko, Iuliia Description: The Smart-Condo™ is a comprehensive platform that aims to provide a variety of services, based on information gleaned from sensors deployed in an apartment, that can potentially improve healthcare delivery. One of our main objectives has been to develop an accurate non-invasive occupant-localization method using passive infrared sensors. In this thesis, we present a simulation framework with which we investigate tradeoffs between the number of sensors and the localization accuracy of our platform. We compare the results of simulations and real-world trials and conclude that our simulation framework is a reliable estimator of the localization accuracy of a particular sensor configuration. We then propose a methodology for planning new deployments that takes into account geometric properties of the new space and the context of occupant's activities. More specifically, we describe a model with the potential to capture typical indoor mobility patterns and formulate a sensor placement optimization problem based on this model. We propose a placement algorithm with near-optimality guarantee. Through simulation-enabled evaluation, we demonstrate that this algorithm generates sensor configurations with localization accuracy superior to that achievable with the same number of sensors placed manually or randomly in the same environment.

The WoW Factor: A Virtual Ethnographic Study of Sacred Things and Rituals in World of Warcraft [Download]
Title: The WoW Factor: A Virtual Ethnographic Study of Sacred Things and Rituals in World of Warcraft Creator: Sonja C. Sapach Description: This paper describes the method of complete participant observation-style virtual ethnography and how it was used to study sacred objects and rituals in the virtual world of Azeroth, from the massively multiplayer online role-playing game (MMORPG) World of Warcraft (WoW). Drawing heavily from the work of Hine (2000), Gold (1958), and Durkheim (1912), and utilizing a case study of the author's MA thesis titled The WoW Factor: The Development of Social Solidarity in Azeroth, this paper provides a detailed description of the unique challenges that a researcher must overcome when planning, and carrying out, an ethnographic study in an MMORPG. Key topics of discussion include: ethical considerations and concerns, recording observations through the use of video-capture and screen-shots, the importance of maintaining the proper balance between being an 'insider' and an 'outsider', and spatial and temporal displacement between the virtual and the real.
