"Smartphone devices are becoming the de facto personal com- puting platform, rivaling the desktop, as the number of smartphone users is projected to reach 1.1 billion by 2013. Unlike the desktop, smartphones have a constrained energy budget, which is further challenged by increasingly sophisti- cated applications. Amongst the most popular applications on smartphone devices are games and virtual environments that rely on 3D graphics. Due to the computational inten- sity of geometry and rasterization, as well as the perpetually illuminated display, these applications are extremely power- hungry. To prolong the battery life of devices running these applications, we propose two new energy-aware adaptation schemes that can be employed in 3D graphics applications: lighting limitation and textural transformation. Our results show that we can conserve between 20% and 33% of energy with acceptable sacrices to a user's visual experience."

Abstract: "The purpose of this research was to develop and test smartphone game application for physical activity promotion in adolescen ts. The first study included various user - centered approaches (e.g. qualitative data, idea sessions) to get feedback on what was desired from the adolescents in terms of game development and design. The second study examined the degree to which mobile heal th studies reported on internal and external validity indicators. The last study evaluated the smartphone game applications through a mixed - methods approach. The results of this research showed that ph ysical activity while playing smartphone game applica tions can yield moderate physical activity intensity. Moreover, adolescents had moderate perceptions of the games and recommended specific changes to the games. Likewise, t he data suggest that smartphone physical activity game applications can be enjoyable if they are aesthetically appealing, easy to use, and foster social peer interactions . Overall, t his research demonstrated that smartphone games that were developed and designed based on adolescents' preferences and persuasive technology design principles could increase physical activity in adolescents and provides a tool for further exploration."

Abstract: "With the increasing potential for gaming hardware and peripherals to support biometrics, their application within the games industry for software and design should be considered. This pa per assesses the ability to use a form of biometric measurement, heart rate, in real - time to improve the challenge and enjoyment of a game by catering it to individuals of varying ability . While the findings of this study are valuable to game developers in terested in providing additional dimensions to gameplay and testing, they may also be useful for those researching medical or the rapeutic applications for games . The results suggest that although the tested game was inherently challenging and enjoyable, t he adaptive affective gameplay was not altering the game enough to induce strong physiological or emotional responses from participants. Biofeedback games lend themselves to medical applications, but adaptive affective games can be used to respond sympathe tically to the player without requiring direct control of physiological responses as a form of input."

Abstract: "The video games industry develops ever more advanced technologies to improve rendering, image quality, ergonomics and user experience of their creations providing very simple to use tools to design new games. In the molecular sciences, only a small number of experts with specialized know-how are able to design interactive visualization applications, typically static computer programs that cannot easily be modified. Are there lessons to be learned from video games? Could their technology help us explore new molecular graphics ideas and render graphics developments accessible to non-specialists? This approach points to an extension of open computer programs, not only providing access to the source code, but also delivering an easily modifiable and extensible scientific research tool. In this work, we will explore these questions using the Unity3D game engine to develop and prototype a biological network and molecular visualization application for subsequent use in research or education. We have compared several routines to represent spheres and links between them, using either built-in Unity3D features or our own implementation. These developments resulted in a stand-alone viewer capable of displaying molecular structures, surfaces, animated electrostatic field lines and biological networks with powerful, artistic and illustrative rendering methods. We consider this work as a proof of principle demonstrating that the functionalities of classical viewers and more advanced novel features could be implemented in substantially less time and with less development effort. Our prototype is easily modifiable and extensible and may serve others as starting point and platform for their developments. A webserver example, standalone versions for MacOS X, Linux and Windows, source code, screen shots, videos and documentation are available at the address: http://unitymol.sourceforge.net/."

From the abstract: "The proposed methodology aims to study the viability of using a game that recreates a fire drill in a 3D environment using Serious Games. The information acquired through the player's performance is very valuable and will be later used to implement an artificial population. A sample of 20 subjects was selected to test the application. Preliminary results are promising, showing that the exercise had a positive impact on users. Moreover, the data acquired is of great important and will be later used to demonstrate the possibility of creating an artificial population based on human behaviour."

Abstract: "Herein is proposed the creation of an Application Program- ming Interface (API) for the Unity 3 and 4 video game de- velopment engine that not only reads behavioral measures from traditional video game input devices (such as if there has been an increase in mouse movements and clicks) but also takes into account physiological measures from biomet- ric devices (such as an increase in respiratory rate). The API parses these inputs based on study results that correlated player performance and engagement with physio- logical signs across several dierent game genres. Through the use of several rudimentary machine learning algorithms, raw physiological data is transformed into data relevant to a developer, including player engagement. The results of these calculations allow a game designer to have powerful tools for detecting when players experience certain emotions, and al- low for the design of aective games. Furthermore, the API also exposes the raw data to de- velopers wishing to propose and utilize their own learning algorithms, to allow for a rich development environment for developers of all skill levels. These development tools will enrich the game experience for the player, as well as prepare designers for the use of the next wave of non-traditional in- put hardware. This report serves to illustrate the current status of the API. A brief overview of the signicance of galvonic skin re- sponse (GSR), heart rate (HR), and respiratory rate (RR) in detecting player performance and engagement will be fol- lowed by a discussion of the API itself and the design choices therein."

Abstract: "In digital games and virtual worlds, like in other digital media, the structure of the medium, its code, influences the emerging interaction and culture. A deliberate modification of this code to facilitate democratic decision making might thus lead to more meaningful interaction in games. If we see virtual worlds as learning environments this might even help players to understand and question real-world power structures. A way to modify the code of a virtual world is by extending its interface with an add-on that interacts with the application programming interface of the game. In this paper we present the design vision and theoretical framework of a digital tool for ethical decision making that will be implemented in the virtual world World of Warcraft. Its purpose will be to supply players with means to modify the power structure built into the code of this virtual world and to support more ethical and democratic decision making in the game."

Abstract: "This literature review describes gamification and how it can be used in a crowdsour cing context. It relates motivations for participating in such activity as more intrinsic than conventional methods, and as such provides numerous benefits. Such benefits include more accurate work, better retention rates, and a more cost effective solutio n. Elements of gamification are examined, as well as how it can be applied to existing applications."

Abstract: "More and more (IT-)suppliers of- fer services to implement gamication in their customers' organizations [2]. What should be considered when start- ing such a project? What are critical success factors to get users involved? This paper is aimed at identifying ways to improve user involvement, specically by target- ing a target audience by its demographics. It aims to do so through literature research and interviews about com- pleted projects. The goal of this research is to add an overview of not only the aforementioned success factors but also a view on if and how they are applied."

Abstract: "We introduce Mechanic Miner, an evolutionary system for discovering simple two-state game mechanics for puzzle platform games. We demonstrate how a re ection-driven generation technique can use a simulation of gameplay to select good mechanics, and how the simulation- driven process can be inverted to produce challenging levels specic to a generated mechanic. We give examples of levels and mechanics generated by the system, summarise a small pilot study conducted with example levels and mechanics, and point to further applications of the technique, including applications to automated game design."

"Automated lm editing involves the generation of the position, orientation, motion and selection of virtual cameras in interactive 3D graphics applications. There is a pressing demand for techniques to assist and automate the control of virtual cameras in the computer games industry where the rapid development of personal computers and high performance consoles has led to substantial improvements in the visual delity of games. The goal of this survey is to characterize the spectrum of applications that require automated lm editing, present a summary of state-of-the-art models and techniques, and identify both promising avenues and hot topics for future research"

Abstract: "This thesis aims to study the design possibilities for supporting explorative form-finding in 3D modeling applications. For today's many design professions, 3D forms are achieved partly in engagement with digital environments. Use of software has far exceeded final idea execution, extending to the early phases of design work in which the outcome is not predetermined. This insight led designers of interactive systems support sketching and ideating activities by reducing the risk of experimentation and cognitive effort demanded from user. Yet, there has been less emphasis on traditional design and craft practice that acknowledges engagement with materials and effort spent on work as an integral part of creative process. The notion of exploration in the scope of this thesis attempts to incorporate such aspects. Relevant literature about workshop practice in design and craft has been reviewed, as well as examples of CAD technologies that aid designers. In this light, HCI perspectives on the design of creativity support tools and games have been discussed. The thesis work aimed to concretize this background by building a design strategy and an interactive artifact. A 3D form-finding application concept using objects in modeling space to indirectly manipulate geometry, "kfields", has been developed and evaluated with users at various stages. The thesis concludes by reflecting on the findings of different design stages and proposing further directions for design. Keywords: 3D Modeling, CAD, digital material, form"

Jane McGonical of Princeton's Institute for the Future makes the case for video game playing and real world applications of the technology. An example she uses is the knowledge base created by World of Warcraft users, the size of which rivals Wikipedia. She contradicts popular images of gamers as solitary and isolated, showing instead community-building and the self-valuation and validation gamers experience from collaborating with others of like interest. She goes on to describe real-world applications of video games, current and potential

Abstract: "Teaching computer programming to novices has always posed a major challenge to educators, most novices acquire basic programming skills but they are unable to utilize them in a meaningful way to solve many of the non-routine problems which are presented to them. As a result, they do not achieve any level of programming fluency. Collaboration has been identified as a useful tool to help overcome this problem if utilized at the right times during the programming/problem solving process. This paper presents a review of computer supported collaborative learning (CSCL) concepts, collaboration in programming and the problem solving domain. Finally, a design for a gaming application of CSCL (COPS) to help improve the problem solving ability of novice programmers is presented."

"Online games increasingly sell virtual goods to generate real income. As a result, it is increasingly important to identify factors and theory of consumption values that affect intent to purchase virtual goods in online games. However, very little research has been devoted to the topic. This study is an empirical investigation of the factors and theory of consumption values that affect intent to purchase virtual goods in online games. The study determines the effects of game type, satisfaction with the game, identification with the character, and theory of consumption values on intent to purchase virtual goods. The study used a survey to collect information from 523 virtual game users. Study results showed that game type is a moderating variable that affects intent to purchase virtual goods. And it demonstrated that role-playing game users are affected by theory of consumption values: functional quality, playfulness, and social relationship support. Moreover, war-strategy game users are affected by satisfaction with the game, identification with the character, and theory of consumption values: price, utility, and playfulness. The study also presents conclusions, proposes applications, and describes opportunities for further research."

Abstract: "As computer games are an increasingly large industry, it is becoming increasingly important for people working in the eld to understand what elements of the game engage the player so as to improve the design of the game. By studying common techniques used in modern games, this paper looks to highlight how the techniques work and thereby provide developers and designers with more information to improve the use of these techniques in future games. The paper also re ects upon the applicability of these techniques outside of games specifically."
