Abstract: "This is a paper that details the issues and problems of the process of implementing a surfing experience simulation - a surfing game. The central issue is using a person's sense of balance as the primary interface controller for a game: this paper details the process the project went through in implementing such an interface, as well as a few games which use it, included for demonstration purposes. The motivation for creating this game came from a discussion of how to integrate an active element of sense of balance into a game interface. This paper also briefly discusses the human-computer interaction (HCI) issues of new interfaces, focused on the recent shift in electronic trends away from the "classical" WIMP (windows, icons, menus and pointing device) design, toward forms of HCI which emulate more closely the natural relationship between a human body and its surroundings."

Abstract: "Brain Quest is an active smart phone game designed to promote both physical activity and executive function in 10-11 year old children. This paper describes the user centred design process which involved a team of psychologists, HCI experts, physical activity specialists and thirty four children over a period of 18 months. Results of two preliminary studies are promising, suggesting that BrainQuest is enjoyable, promotes moderate physical activity and has the potential to provide cognitive scaffolding of the key executive function (EF) skill of multitasking."

"During recent years "gamification" has gained significant attention among practitioners and game scholars. However, the current understanding of gamification has been solely based on the act of adding systemic game elements into services. In this paper, we propose a new definition for gamification, which emphases the experiential nature of games and gamification, instead of the systemic understanding. Furthermore, we tie this definition to theory from service marketing because majority of gamification implementations aim towards goals of marketing, which brings to the discussion the notion of how customer / user is always ultimately the creator of value. Since now, the main venue for academic discussion on gamification has mainly been the HCI community. We find it relevant both for industry practitioners as well as for academics to study how gamification can fit in the body of knowledge of existing service literature because the goals and the means of gamification and marketing have a significant overlap."

From the abstract: "we present Bubble Popper, an exertion game that considers and facilitates body contact. Bubble Popper, which uses very simple technology, also demonstrates that considering and facilitating body contact can be achieved without t he need to sense body contact. Through reflecting on our design and analyzing observations of play , we are able to articulate what impact physical space layout in relation to digital game elements, and physical disparity between input and digital display c an have on body contact. Our results aid game designers in creat ing engaging exertion game s by guiding them when considering body contact, ultimately helping players benef it more from engaging exertion games."

Abstract: "HCI scholars have been among those attracted to the study of online, computer-supported gaming. "Big Data" approaches, which analyze electronic traces left by game play, are an increasingly popular way to study it. This paper identifies basic epistemological problems in some such approaches, focusing on those that implicitly depend on the assumption that game play is fundamentally the same as other social activity. The paper explains why this and related assumptions are questionable, and why these Big Data approaches cannot establish their validity on their own. The paper then reports some results of a preliminary ethnographic study of Massive Multiplayer Online Games (MMOGs), in order to illustrate a way that ethnography can provide an initial purchase on how the underlying similarity/dissimilarity issue can be studied. It concludes by explaining how methodological triangulation, involving a dialectical discourse between ethnography, on the one hand, and Big Data and similar approaches, on the other, may be able to place Game Studies on a firmer epistemological foundation. It is the attempt to achieve such significant objectives, in particular to justify a foundational critique of a major new development in Game Studies, and to do so in a single paper, that justify inclusion of the paper in alt.chi.

Abstract: "This paper describes the design and evaluation of Zoo U, a novel computer game to assess children's social skills development. Zoo U is an innovative product that combines theory-driven content and customized game mechanics. The game-like play creates the opportunity for stealth assessment, in which dynamic evidence of social skills is collected in real time and players' choices during gameplay provide the needed data. To ensure the development of an engaging and valid game, we utilized an iterative datadriven validation process in which the game was created, tested, revised based on student performance and feedback, and retested until game play was statistically matched to independent ratings of social skills. We first investigated whether the data collected through extensive logging of student actions provided information that could be used to improve the assessment. We found that detailed game logs of socially relevant player behavior combined with external measures of player social skills provided an efficient vector to incrementally improve the accuracy of the embedded assessments. Next, we investigated whether the game performance correlated with teachers' assessments of students' social skills competencies. An evaluation of the final game showed (a) significant correlations between in-game social skills assessments and independently obtained standard psychological assessments of the same students and (b) high levels of engagement and likeability for students. These findings support the use of the interactive and engaging computer game format for the stealth assessment of children's social skills. The created innovative design methodologies should prove useful in the design and improvement of computer games in education."

Abstract: "Persuasive games are an effective approach for motivating health behavior, and recent years have seen an increase in games designed for changing human behaviors or attitudes. However, these games are limited in two major ways: first, they are not based on theories of what motivates healthy behavior change. This makes it difficult to evaluate why a persuasive approach works. Second, most persuasive games treat players as a monolithic group. As an attempt to resolve these weaknesses, we conducted a large-scale survey of 642 gamers' eating habits and their associated determinants of healthy behavior to understand how health behavior relates to gamer type. We developed seven different models of healthy eating behavior for the gamer types identified by BrainHex. We then explored the differences between the models and created two approaches for effective persuasive game design based on our results. The first is a one-size-fits-all approach that will motivate the majority of the population, while not demotivating any players. The second is a personalized approach that will best motivate a particular type of gamer. Finally, to make our approaches actionable in persuasive game design, we map common game mechanics to the determinants of healthy behavior."

"how game environments can be designed to support many kinds of sociability"

Abstract: "Older adults in nursing homes often lead sedentary lifestyles, which reduces their life expectancy. Full-body motion-control games provide an opportunity for these adults to remain active and engaged; but these games are not designed with age-related impairments in mind, which prevents the games from being leveraged to increase the activity levels of older adults. In this paper, we create a gardening game specifically addressing institutionalized older adults. Additionally, we present an evaluation of the game that demonstrates how full-body motion-control games can accommodate a variety of user abilities, have a positive effect on mood and, by extension, the emotional well-being of older adults, thereby increasing their quality of life."

"a casual game that addresses childhood cancer: Besides mere entertainment, a health game that focuses on cancer may serve as a clinical tool in order to teach children about the particularities of the disease and initiate discussion among cancer patients, their parents and medical staff. In this context, the results of an empirical study revealed a generally high acceptance of the health game among young patients, while parents and medical staff highlighted the educational potential of health games addressing cancer. Additionally, we discuss the challenges of evaluating digital games in a hospital setting which were revealed during the evaluation phase."

"first, we give empirical evidence that shows the extent to which productive training (i.e. vocalizing words) is superior to receptive vocabulary training, and discuss the use of scaffolding hints to "unpack" factors in the learner‟s linguistic knowledge that may impact reading. Second, we discuss what our results suggest for future research in HCI."

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"
