Description
This study looked at ways of understanding how schoolyards might act as meaningful places in children's developing sense of identity and possibility. Photographs and other images such as historical photographs and maps were used to look at how built environments outside of school reflect demographic and social differences within one southwest city. Intersections of children's worlds with various socio-political communities, woven into and through schooling, were examined for evidence of ways that schools act as the embodiment of a community's values: they are the material and observable effects of resource-allocation decisions. And scholarly materials were consulted to examine relationships in the images to existing theories of place, and its effect on children, as well as to consider theories of the hidden curriculum and its relationship to social reproduction, and the nature of visual representation as a form of data rather than strictly in the service of illustrating other forms of data. The focus of the study was on identifying appropriate research methods for investigating ways to understand the importance of the material worlds of school and childhood. Using a combination of visual and narrative approaches to contribute to our understanding of those material worlds, I sought to expose areas of inequity and class differences in ways that children experience schooling, as evidenced by differences in the material environment. Using a mixed-methods approach, created and found images were coded for categories of material culture, such as the existence of fences, trees, views from the playground or walking in the neighborhood at four Tempe schools. Findings were connected to a rich body of knowledge in areas such as theories of space and place, the nature of the hidden curriculum, visual culture, visual research methods including mapping. Familiar aspects of schooling were exposed in different ways, linking past decisions made by adults to their continuing effects on children today. In this way I arrived at an expanded and enriched understanding of the present worlds of children communicated as through the material environment. Visually examining children's worlds, by looking at the material artifacts of everyday worlds that children experience at school and including the child's-eye view in decision processes, has promise in moving decision makers away from strictly analytical and impersonal approaches to decision making about schooling children of the future. I proposed that by weighting of data points, as used in decision-making processes regarding schooling, differently than is currently done, and by paying closer attention to possible longer-term effects of place for all children, not just a few, there is the potential to improve the quality of life for today's children, and tomorrow's adults.

Description
Human experience exists within space; it is the studio for the stories of our lives. Bounded by time, location and personal experience we assign our own meanings and feelings to them, and they become personal, symbolic places: some are unique to us, imagined places where we act out stories or dreams; most are part of the natural world.
Most spaces, though, are built or controlled by others; these constructed environments can become places where we may, or may not, like to be.
This research examined spaces and places of children's lives through the material worlds of their neighborhoods and schools, focusing on the visible environment outside of the school building. The intersection of school and community, it is a material embodiment of, and evidence toward, how a community's resources are apportioned to
important aspects of children's developmental years. These visible representations speak of that society's values and goals for the children for whom they (we) are responsible.
This examination used multiple research tools, primarily using visual approaches such as current photographs, archival images and data, descriptive census materials and maps. Historical documents, (many of which are now digitized), as well as other academic literature, local journalistic efforts and school district publications added important materials for analysis.
Findings lead to deeper understanding of ways that visible, material worlds of schools and neighborhoods -- past and present - can reflect, and direct the experiences of childhood today, and often mirror those of children past. These visual and narrative approaches contributed to understanding the importance of material evidence in revealing
inequity and class differences in ways that children, then, must &ldquodo school &rdquo

Description
The video game graphics pipeline has traditionally rendered the scene using a polygonal approach. Advances in modern graphics hardware now allow the rendering of parametric methods. This thesis explores various smooth surface rendering methods that can be integrated into the video game graphics engine. Moving over to parametric or smooth surfaces from the polygonal domain has its share of issues and there is an inherent need to address various rendering bottlenecks that could hamper such a move. The game engine needs to choose an appropriate method based on in-game characteristics of the objects; character and animated objects need more sophisticated methods whereas static objects could use simpler techniques. Scaling the polygon count over various hardware platforms becomes an important factor. Much control is needed over the tessellation levels, either imposed by the hardware limitations or by the application, to be able to adaptively render the mesh without significant loss in performance. This thesis explores several methods that would help game engine developers in making correct design choices by optimally balancing the trade-offs while rendering the scene using smooth surfaces. It proposes a novel technique for adaptive tessellation of triangular meshes that vastly improves speed and tessellation count. It develops an approximate method for rendering Loop subdivision surfaces on tessellation enabled hardware. A taxonomy and evaluation of the methods is provided and a unified rendering system that provides automatic level of detail by switching between the methods is proposed.

Description
Night vision goggles (NVGs) are widely used by helicopter pilots for flight missions at night, but the equipment can present visually confusing images especially in urban areas. A simulation tool with realistic nighttime urban images would help pilots practice and train for flight with NVGs. However, there is a lack of tools for visualizing urban areas at night. This is mainly due to difficulties in gathering the light system data, placing the light systems at suitable locations, and rendering millions of lights with complex light intensity distributions (LID). Unlike daytime images, a city can have millions of light sources at night, including street lights, illuminated signs, and light shed from building interiors through windows. In this paper, a Procedural Lighting tool (PL), which predicts the positions and properties of street lights, is presented. The PL tool is used to accomplish three aims: (1) to generate vector data layers for geographic information systems (GIS) with statistically estimated information on lighting designs for streets, as well as the locations, orientations, and models for millions of streetlights; (2) to generate geo-referenced raster data to suitable for use as light maps that cover a large scale urban area so that the effect of millions of street light can be accurately rendered at real time, and (3) to extend existing 3D models by generating detailed light-maps that can be used as UV-mapped textures to render the model. An interactive graphical user interface (GUI) for configuring and previewing lights from a Light System Database (LDB) is also presented. The GUI includes physically accurate information about LID and also the lights' spectral power distributions (SPDs) so that a light-map can be generated for use with any sensor if the sensors luminosity function is known. Finally, for areas where more detail is required, a tool has been developed for editing and visualizing light effects over a 3D building from many light sources including area lights and windows. The above components are integrated in the PL tool to produce a night time urban view for not only a large-scale area but also a detail of a city building.

Description
Distant is a Game Design Document describing an original game by the same name. The game was designed around the principle of core aesthetics, where the user experience is defined first and then the game is built from that experience. Distant is an action-exploration game set on a huge megastructure floating in the atmosphere of Saturn. Players take on the role of HUE, an artificial intelligence trapped in the body of a maintenance robot, as he explores this strange world and uncovers its secrets. Using acrobatic movement abilities, players will solve puzzles, evade enemies, and explore the world from top to bottom. The world, known as the Strobilus Megastructure, is conical in shape, with living quarters and environmental system in the upper sections and factories and resource mining in the lower sections. The game world is split up into 10 major areas and countless minor and connecting areas. Special movement abilities like wall running and anti-gravity allow players to progress further down in the world. These abilities also allow players to solve more complicated puzzles, and to find more difficult to reach items. The story revolves around six artificial intelligences that were created to maintain the station. Many centuries ago, these AI helped humankind maintain their day-to-day lives and helped researchers working on new scientific breakthroughs. This led to the discovery of faster-than-light travel, and humanity left the station and our solar system to explore the cosmos. HUE, the AI in charge of human relations, fell into depression and shut down. Awakening several hundred years in the future, HUE sets out to find the other AI. Along the way he helps them reconnect and discovers the history and secrets of the station. Distant is intended for players looking for three things: A fantastic world full of discovery, a rich, character driven narrative, and challenging acrobatic gameplay. Players of any age or background are recommended to give it a try, but it will require investment and a willingness to improve. Distant is intended to change players, to force them to confront difficulty and different perspectives. Most games involve upgrading a character; Distant is a game that upgrades the player.

Description
The purpose of the Oculus Exercise research project we conducted was to find a way to entice individuals to attend a gym more often and for longer periods of time. We have found that many activities are being augmented by the increasingly popular virtual reality technology, and within that space "gamifying" the activity seems to attract more users. Given the idea of making activities more entertaining to users through "gamification", we decided to incorporate virtual reality, using the Oculus Rift, to immerse users within a simulated environment to potentially drive the factors previously identified in respect to gym utilization. To start, we surveyed potential users to gauge potential interest in virtual reality and its usage in physical exercise. Based on the initial responses, we saw that there was a definite interest in "gamifying" physical exercises using virtual reality, and proceeded to design a prototype using Unreal Engine 4 -- which is an engine for creating high quality video games with support for virtual reality -- to experiment how it would affect a standard workout routine. After considering several options, we decided to move forward with designing our prototype to augment a spin machine with virtual reality due to its common usage within a gym, and the consistent cardiovascular exercise it entails, as well as the safety intrinsic to it being a mostly stationary device. By analyzing the results of a survey after experimenting upon a user test group, we can begin to correlate the benefits and the drawbacks of using virtual reality in physical exercise, and the feasibility of doing so.

Young adults do not know basic emergency preparedness skills. Although there are materials out there such as printed and online materials form Center for Disease Control, it is unlikely that college-age people will take the time to read them. Some individuals have addressed the issue of young adults not wanting to read materials by creating a fun interactive game in the San Francisco area, but since the game must be played in person, a solution like that can only reach so far. Studies suggest that virtual worlds are effective in teaching people new skills, so I have created a virtual world that will teach people basic emergency preparedness skills in a way that is memorable and appealing to a college-age audience. The logic used to teach players the concepts of emergency preparedness is case-based reasoning. Case-based reasoning is the process of solving new problems by remembering similar solutions in the past. By creating a simulation emergency situation in a virtual world, young adults are more likely to know what to do in the case of an actual emergency.

Description
Keyboard input biometric authentication systems are software systems which record keystroke information and use it to identify a typist. The primary statistics used to determine the accuracy of a keyboard biometric authentication system are the false acceptance rate (FAR) and false rejection rate (FRR), which are aimed to be as low as possible [1]. However, even if a system has a low FAR and FRR, there is nothing stopping an attacker from also monitoring an individual's typing habits in the same way a legitimate authentication system would, and using its knowledge of their habits to recreate virtual keyboard events for typing arbitrary text, with precise timing mimicking those habits, which would theoretically spoof a legitimate keyboard biometric authentication system into thinking it is the intended user doing the typing. A proof of concept of this very attack, called keyboard input biometric authentication spoofing, is the focus of this paper, with the purpose being to show that even if a biometric authentication system is reasonably accurate, with a low FAR and FRR, it can still potentially be very vulnerable to a well-crafted spoofing system. A rudimentary keyboard input biometric authentication system was written in C and C++ which drew influence from already existing methods and attempted new methods of authentication as well. A spoofing system was then built which exploited the authentication system's statistical representation of a user's typing habits to recreate keyboard events as described above. This proof of concept is aimed at raising doubts about the idea of relying too heavily upon keyboard input based biometric authentication systems since the user's typing input can demonstrably be spoofed in this way if an attacker has full access to the system, even if the system itself is accurate. The results are that the authentication system built for this study, when ran on a database of typing event logs recorded from 15 users in 4 sessions, had a 0% FAR and FRR (more detailed analysis of FAR and FRR is also presented), yet it was still very susceptible to being spoofed, with a 44% to 71% spoofing rate in some instances.

Description
This paper will explore what makes ‘good’ virtual reality, that is, what constitutes the virtual reality threshold. It will explain what this has to do with the temporary death of virtual reality, and argue that that threshold has now been crossed and true virtual reality is now possible, as evidenced by the current wave of virtual reality catalyzed by the Oculus Rift. The Rift will be used as a case study for examining specific aspects of the virtual reality threshold.
