Abstract: "Reality-based interfaces bring new design opportunities to social games. These novel game interfaces, exemplified by Wii, Kinect, and Smart phones, leverage players' existing physics, bodily, environmental, and social skills. Moreover, they enable a shared hybrid physical-digital space in which the players' co-presence can be enhanced by their physical and digital co-location. However, many digital social games occupy players' attention with the digital display and content, reducing their attention spent on one another and limiting the synchronization of actions and emotions among players. How do we design technologies that do not interfere with social play but enhance and innovate it? In this thesis work, I focus on one particular kind of reality-based interfaces, Handheld Augmented Reality (HAR), to extend players' interaction from the small mobile devices to the shared hybrid space around a computationally trackable surface. This thesis explores how to encourage social play with HAR interfaces, which brings in challenges of designing with the affordances and constraints of the HAR interface, understanding the complicated phenomenon of social play, and integrating these understandings in multiplayer HAR game design. Adopting Research-through Design as the overarching research method, I collaborate with multiple teams, design and study three multiplayer HAR game prototypes. I present four main contributions. First, this work yields design artifacts and examples of social games with HAR interfaces. I communicate to the game design and Augmented Reality communities through these prototypes, including BragFish, ARt of Defense, and NerdHerder. Second, I provide empirical findings on social play in a shared hybrid space. Through lab-based user studies, observation, video analysis, interviews, and surveys, I collect and analyze interpersonal play behaviors and emotions in the shared hybrid space enabled by the HAR interface. Third, I adopt and adapt sociologic

abstract: "Creating graphical user interfaces (GUI) for stereoscopic 3D (S3D) games is a difficult choice between visual comfort and effect. We present a S3D Game GUI Design Space and a list of S3D-specific attributes that emphasizes integrating visually comfortable interfaces into the game world, story and S3D view. To showcase our approach, we created two GUI concepts and evaluated them with 32 users. Our results show quality improvements for a combination of bottom position and visual attachment for a menu. In a referencing interface, placing the reference near to the target depth significantly improved perceived quality, game integration, and increased presence. These results confirm the need to create S3D GUIs with perceptual constraints in mind, demonstrating the potential to extend the user experience. Additionally, our design space offers a formal and flexible way to create new effects in S3D GUIs."

From a book on haptic interfaces ,"Currently, a diverse spectrum of games available in the market take advantage of the force feedback stimuli effects offered by mainstream haptic interfaces. Here we intend to give a broad view of past and present developments aimed at enabling game environment with haptic augmented interfaces, while discussing the strengths and weaknesses of such developments."

"This project involves developing an action-platformer game for the Flash platform. The user controls a character who must progress through levels, while avoiding obstacles, collecting items and fighting many types of enemies. Role-playing game elements such as equipment and upgrades support user customization and varied battle strategies. Developing a successful Flash game involves several factors. Flash games must be simple to get into, yet rewarding to play in both short and long sessions. Flash games must be accessible to a wide audience; both in terms of user preferences and technical limitations. Finally, Flash games must offer something unique to stand out from the crowd, in a market where hundreds of free games are published every month. This report covers the research, design and implementation done to achieve these requirements, in terms of game mechanics, interface, level design, visual design, accessibility options, and replay value. Technical challenges include building, testing and optimizing a game engine and interface from scratch, balancing the game mechanics and difficulty, and structuring the whole development process in a way that enables easy creation of new content. In addition to game design and development, this project also deals with the business aspects of developing online games; how games generate revenue, how they are marketed and distributed, and developing trends in the consumer market. Project success in different areas has been evaluated through usability studies, user ratings and reviews, and vast quantities of usage and distribution statistics. Overall, the project has been a success in terms of user reception and generated revenue, and the final section of this report includes plans for a second game, utilizing and building upon the same game engine and mechanics."

Abstract: "In recent years videogame companies have recognized the role of player engagement as a major factor in user experience and enjoyment. This en-couraged a greater investment in new types of game controllers such as the WiiMote™, Rock Band™ instruments and the Kinect™. However, the native software of these controllers was not originally designed to be used in other game applications. This work addresses this issue by building a middleware framework, which maps body poses or voice commands to actions in any game. This not only warrants a more natural and customized user-experience but it al-so defines an interoperable virtual controller. In this version of the framework, body poses and voice commands are respectively recognized through the Ki-nect's built-in cameras and microphones. The acquired data is then translated into the native interaction scheme in real time using a lightweight method based on spatial restrictions. The system is also prepared to use Nintendo's Wiimote™ as an auxiliary and unobtrusive gamepad for physically or verbally impractical commands. System validation was performed by analyzing the per-formance of certain tasks and examining user reports. Both confirmed this ap-proach as a practical and alluring alternative to the game's native interaction scheme. In sum, this framework provides a game-controlling tool that is totally customizable and very flexible, thus expanding the market of game consumers."

Abstract: "Game design and development still needs complex technical skills that only some people master. This can be a huge barrier to game creation by end-users limiting the emergence of a participatory culture around games - similar to the one we have seen with Web 2.0. While there have been approaches to lessen that problem, such as level editors and content creation tools, we think we could go further. We propose that considering and developing design interfaces that make use of common natural skills such as drawing could be a key step to achieve that phenomenon. Therefore we describe and present the Playsketch concept, and it's current implementation, a game creation approach based on the Paper Prototyping concept which invites the users to create simple personalized games."

Abstract: "As a way to support developers , we propose the creation of specialized tools to deal with accessibility. The hypothesis defined was that it is possible to produce tools that coul d reduce the cost and effort needed to adapt games for people with special needs while achi eving a sufficient level of usability and a pleasant player exper ience . Because of the ambitious of the approach , the goal of the project is to explore if it is feasible through preliminary research . T hree experiments were set up to cover and explore different alternatives , given the diversity of player characteristics and game develop ment approaches . In these experiments we targeted t wo different platforms: a desktop game authoring tool oriented to educators , and a mobile game development framework oriented to programmers . In these experiments we used the to ols developed to produce several games that were also tested by end users . While the project focuses on disability, the ideas proposed can be generalized and applied to support optimizing game interfaces for a wide and diverse audience."

Abstract Virtual worlds give us the opportunity to explore another self, a virtual character of the real life you. Massively Multiplayer Online Role Playing Games (MMORPGs) have become extremely popular over the last decade. It has also grown into a lucrative business. To keep the players, the game needs to be more than just a game. This study aimed at finding out what factors that determine which features of the character creation interface that are most important to players. The following research question was formed; "Which underlying factors affect how important different features of the character creation interface are to experienced MMORPG players? To be able to answer the question an extensive literature review was conducted. A qualitative approach was taken. Long interviews were made with five participants, two female and three male players. The interviews took place while they created a number of avatars in different MMORPGs. The interviews were then followed up. During the follow-ups, the impact the character creation process had for the players, were discussed. The findings indicate that the character creation interface is important for the players to get a good gaming experience. However different types of players require different things. Important features for the users to change were mainly; the head; the name; and adding parts of yourself on your character. The factors that determined the importance of these features were found to be; Player types; Identity types; Immersion levels; and whether or not the game or the gaming experience were new to the player. Another finding showed that the longer you have played a game the less bizarre the different races, classes and gender will seem. The study also indicated that the female participants had a hard time identifying with their male characters."

Abstract: "The purpose of this study is to create a brain-computer interface-dependent game that relies on user affect as a method of control. The paper first summarizes the existing research into BCI-based applications. It then describes the steps the researchers have been taking in order to develop a game that makes use of the OCZ Neural-Impulse Actuator to retrieve brain signals from a user in order to manipulate different powers utilizing arousal."

"This project created an Application Programming Interface (API) for a simulated modular digital game system. Each module consists of a triangle that displays colors at the center and edges, monitors an input and signals from the surrounding modules, and communicates with a computer controller. The API allows users to develop game programs for the system. The simulation runs the game files and displays the results. The focus was on practical coding and design of an instructional game system. The challenges in creating such a system provided a valuable learning environment for us in the areas of user interface design, system tool management and design, human computer interaction, and designing educational platforms"

Abstract This paper describes the use of skill atoms as a design lens for gameful design that focuses the optimal structuring of challenges inherent in a user's goal pursuit.

From the abstract: "A serious game for construction planning and scheduling education must provide an authentic environment for gameplay. To achieve this requirement, the game environment must be created from CAD drawings of a real project. The game engine must have components for providing timely scaffolding and support to the user. Storing the vast amount of data for a real project requires data structures optimized for fast rendering at the same time easily accessing and manipulating building elements and element data. This paper discusses a game engine developed for creating construction planning and scheduling educational games. The game engine is designed from scratch for performance and flexibility. It includes a component for directly importing data from a Revit model for building the game environment, interfaces Microsoft Project for scheduling, includes a feedback module, and a scoring system for measuring user performance."

"Game design is a sibling discipline to software and Web design, but they're siblings that grew up in different houses. They have much more in common than their perceived distinction typically suggests, and user experience practitioners can realize enormous benefit by exploiting the solutions that games have found to the real problems of design."

Abstract: "In this paper, we explore the application of Software Product Line (SPL) technology in the video games domain by exploiting differences in various video game platforms to design a variable component - based software product line architecture for a multiplatform vide o game . Our approach consists of constructing a feature dependency model for describing variability in multiplatform video games. We explored variability in the user interface, input devices, output devices, CPU, as well as other variability in various vid eo game platforms. Then, we designed a variable component - based SPL that is tailored to every video game in the product line. We validated our approach by implementing a SPL of a combat flight - simulator game and by deriving two versions of the game: a Win dows desktop version and a Windows Phone version. The derivation process of each version is done by selecting features from the feature dependency model and the corresponding software components and SPL parameters that relate to those features. "

Abstract: "Location-based mobile gaming combines gameplay with physical ac tivity. We have developed a game, O- Mopsi, based on the concept of orienteering, which can be played on mobile phones with GPS receiver and Internet connection. In order to complete a game, a play er must visit a set of targets that are photos chosen from a user-generated geotagged database. Game crea tion, management and live tracking can be done using a web interface. The game was presented at an annual international festival whic h is aimed at introducing science and technology to school children and the overa ll feedback received from the players was positive.

From the introduction: "With the sudden and massive influx of mobile technologies, the need for efficient agile techniques in the video game de- velopment industry has amplified further. With relatively short lifecycles and unique input, size, and performance constraints, as well as dealing with a wide range of device hardware, the industrys development process as a whole has had to adapt in order to survive. We present a subset of these adopted methods and technologies as they pertain to agile development in the video game industry."

Abstract: "ideo games and other applications using off - the - shelf tracking devices often take a simple approach to gesture and pose recognition: a recognized gesture is always mapped to the same action . This approach basically turns a gesture into a binary button pre ss and misses much of the nuance implicit in natural gestures. In this paper we explore , in a game design setting , the use of continuous 3D gesture sequences where in attributes of individual gestures, such as speed, direction, etc., combine to influence th e r esult of the sequence as a whole . We present Pixelbending, a game demo built using the Microsoft Kinect and Unreal Developers Kit (UDK) in which the player performs Tai Chi inspired movements to control water. Designed with the goal of creating a fun an d engaging 3D game experience built on a nuanced gesture set, the demo was well received by many players of different ages and sizes. Through the development process we encountered challenges to working with off - the - shelf devices."
