Creating a Virtual Training Environment for Traffic Accident Creating a Virtual Training Environment for Traffic Accident Investigation for the Dubai Police Force Ahmed BinSubaih Doctor of Philosophy Department of Computer Science University of Sheffield October 2007 Abstract This research investigates the use of gaming technology (especially game engines) in developing virtual training environments, and comprises of two main parts. The first part of the thesis investigates the creation of an architecture that allows a virtual training environment (i.e. a 'game') to be portable between different game engines. The second part of the thesis examines the learning effectiveness of a virtual training environment developed for traffic accident investigators in the Dubai police force. The second part also serves to evaluate the scalability of the architecture created in the first part of the thesis. Current game development addresses different aspects of portability, such as porting assets and using middleware for physics. However, the game itself is not so easily portable. The first part of this thesis addresses this by making the three elements that represent the game's brain portable. These are the game logic, the object model, and the game state, which are collectively referred to in this thesis as the game factor, or G-factor. This separation is achieved by using an architecture called game space architecture (GSA), which combines a variant of the model-view-controller (MVC) pattern to separate the G-factor (the model) from the game engine (the view) with on-the-fly scripting to enable communication through an adapter (the controller). This enables multiple views (i.e. game engines) to exist for the same model (i.e. G-factor). The principal findings from the evaluation process reveal that GSA is capable of servicing the same G-factor to multiple game engines and that it supports modifiability. They also reveal that GSA adds little development overhead. The ability of GSA to scale to real world applications is demonstrated by the development of a virtual training environment. The second part of the thesis examines the development of a virtual training environment for traffic accident investigators in the Dubai police force. Their training needs were identified in a field study conducted in the summer of 2004 to assess the current training methods of lectures and on-the-job training. The virtual environment was then developed by combining game design and instructional design to ensure the learning objectives were integral to the gameplay. To evaluate the learning effectiveness of the virtual environment an experiment was conducted in February and March of 2006 for fifty-six police officers from the Dubai police force. They were divided into two groups: novices (0 to 2 years experience) and experienced investigators (with more than 2 years experience). The experiment revealed significant performance improvements in both groups, with the improvement reported in novices significantly higher than the one reported in experienced investigators. i Acknowledgements I would like to thank the Commander-in-Chief of Dubai Police, Lieutenant General Dhahi Khalfan Tamim for his constant encouragement ever since finishing my master's degree to pursue a PhD. I am also grateful to the Dubai police force for sponsoring this work. I would like also to thank my fellow officers in the Dubai police force for their support without which the field study and the experiments would have been very difficult to carry out. They have put up with my constant interruptions and did not mind me following them with a camera. They have gone out of their duty to help this endeavour. The serious game developed as part of this thesis would not have reached its current state without the constant refinement and without the expertise of the subject matter experts especially Brigadier Mohammed Al Zaffin, Lieutenant Colonel Mohammed Al-Ali, Major Khalid Kinsham, Major Omar Ashour, Captain Maher Bin Haider, and many others from the Dubai Traffic Department. During the field study, my first stop was to work at Bur Dubai police station and it was an experience that was made very insightful with the expertise, professionalism, and support of officers there. This list is by no means a comprehensive one. In fact, more than 100 officers contributed in one way or another. This work will always be indebted to you. I am also grateful to my friends in Sheffield who helped test the serious game. These are Khalfan Al Shoaili, Nasser Al Yarubi, Ahmed Al Shokaili, Ayoub Al Awadi, and Ahmed Bin Humaidan. I would like to express my sincere appreciation to my supervisor Dr. Steve Maddock. He was very influential in motivating me to do a PhD and the reason for selecting the University of Sheffield for another educational journey after already having done my undergraduate studies here. His endless support, encouragement, and invaluable guidance have made it all possible. I would also like to thank my second supervisor Dr. Daniela Romano for her motivation and her useful suggestions and feedback. Also thanks to my original second supervisor Dr. Gordon Manson and the panel for their comments and constructive criticism. This work is also shaped by comments from reviewers during the publication of the material in conferences, in a journal, and in a book chapter whose names remain unknown. Thank you all so much. Many thanks to all the members of the graphics group (past and present) for their help along the way. They have made the journey more tolerable and knowledgeable. Thanks to now Dr. Mike Meredith for his technical support and participating in the exchanges of jibes often about our social life or lack of it. Thanks to now Dr. James Edge for discussing my ideas, proof reading, and encouraging me to publish. Thanks to now Dr. Manuel Sanchez for sharing his knowledge about game development. Many thanks also to Dr. Alan Watt for keeping an eye on me when in fact someone needs to keep an eye on him! Many thanks also to the Sheffield Academy of ii Martial Arts where it was nice to get rid of all the frustration even though it sometimes meant being used as a punching bag. It was all worth it to teach me to keep my guards up and persevere. Many thanks to Sifu Graham Abdulla, his brother Adrian, and others at the academy for making me part of the Lau Gar Kung Fu family. What I have learned from you guys will always stay with me. This thesis would not have been possible without the endless support from my family and friends. I would specially like to thank my family for being patient despite the long gaps between visits. What made this even more difficult for me was missing on my nephews and nieces growing up. Also thank you for putting up with me forgetting sometimes how to behave in a conservative culture. This is partly to be blamed on the English Sitcom (Dad's Army, Steptoe and Son, Only Fools and Horses, Hancock's Half Hour, On the Buses, Till Death Us Do Part, Love Thy Neighbour, etc) and partly for spending 11 years in the UK. The journey started from learning English in 1994 in Torquay to this day with few years in between spent working in the Dubai police force. When I go back home I probably need a crash course (or a serious game) on culture. iii Research Publications Refereed Publications BinSubaih, A., Maddock, S., and Romano, D. (2008).

  • The Uses of Animation 1
    The Uses of Animation 1 1 The Uses of Animation ANIMATION Animation is the process of making the illusion of motion and change by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon. Animators are artists who specialize in the creation of animation. Animation can be recorded with either analogue media, a flip book, motion picture film, video tape,digital media, including formats with animated GIF, Flash animation and digital video. To display animation, a digital camera, computer, or projector are used along with new technologies that are produced. Animation creation methods include the traditional animation creation method and those involving stop motion animation of two and three-dimensional objects, paper cutouts, puppets and clay figures. Images are displayed in a rapid succession, usually 24, 25, 30, or 60 frames per second. THE MOST COMMON USES OF ANIMATION Cartoons The most common use of animation, and perhaps the origin of it, is cartoons. Cartoons appear all the time on television and the cinema and can be used for entertainment, advertising, 2 Aspects of Animation: Steps to Learn Animated Cartoons presentations and many more applications that are only limited by the imagination of the designer. The most important factor about making cartoons on a computer is reusability and flexibility. The system that will actually do the animation needs to be such that all the actions that are going to be performed can be repeated easily, without much fuss from the side of the animator.

L337 SOCCER MOMS CONCEPTIONS OF “HARDCORE” AND “CASUAL” IN THE DIGITAL GAMES MEDIUM by STEVEN BOYER Under the Direction of Ted Friedman ABSTRACT As digital games have become increasingly significant in the entertainment media landscape, the terms “casual” and “hardcore” have become the primary ways to describe gaming audiences, genres, and gameplay. However, these terms are saturated with outdated stereotypes involving gender, age, and class. Focusing on industrial discourse, this thesis examines this dichotomy, emphasizing areas of discontinuity and overlap to question why these terms have become so ubiquitous in gaming discourse and what functions they fulfill for a variety of groups including the industry, advertisers, and audience members. Ultimately, I suggest that these terms need to be replaced in order to move beyond restrictive stereotypes, proposing a new framework for digital games that takes into consideration user motivation, personal investment, and historical specificity.

This includes part of it, is still lagging behind. Since the launch of that industry a new approach for game engines and more generally interactive and mostly throughout its history, games, or in case of server- media engines for entertainment, training, educational and based multi-user games, thick game clients have been single- dashboard applications. Porting traditional game engines and user applications running completely on end-user devices. These interactive media engines to the cloud without fundamentally needs had a significant impact on the architecture of the game changing the architecture, as done frequently, can enable already various advantages of cloud computing for such kinds of and media engines being the software which provides core applications, for example simple and transparent upgrading of functionalities like input handling, game simulation, AI, content and unified user experience on all end-user devices.
