Exergame design for elderly users: the case study of SilverBalance

In this paper, we discuss chances and challenges of game design for an elderly audience with a focus on the development of safe and usable exertion games for frail senior citizens. Based on an analysis of theoretical constraints, we conducted a case study which implements different balance tasks for elderly players featuring the Nintendo Wii Balance Board which encourages users to actively engage in game play. Furthermore, we tested the feasibility of the board as input device for our case study SilverBalance. Our results indicate that age-related impairments influence the use of video games among frail elderly in many respects, hence their needs have to be considered during the design process. In this context, our paper provides a foundation for future research regarding digital games for the elderly. © 2010 ACM

Optimal configuration of active and backup servers for augmented reality cooperative games

Interactive applications as online games and mobile devices have become more and more popular in recent years. From their combination, new and interesting cooperative services could be generated. For instance, gamers endowed with Augmented Reality (AR) visors connected as wireless nodes in an ad-hoc network, can interact with each other while immersed in the game. To enable this vision, we discuss here a hybrid architecture enabling game play in ad-hoc mode instead of the traditional client-server setting. In our architecture, one of the player nodes also acts as the server of the game, whereas other backup server nodes are ready to become active servers in case of disconnection of the network i.e. due to low energy level of the currently active server. This allows to have a longer gaming session before incurring in disconnections or energy exhaustion. In this context, the server election strategy with the aim of maximizing network lifetime is not so straightforward. To this end, we have hence analyzed this issue through a Mixed Integer Linear Programming (MILP) model and both numerical and simulation-based analysis shows that the backup servers solution fulfills its design objective

Custom-designed motion-based games for older adults: a review of literature in human-computer interaction

Many older adults, particularly persons living in senior residences and care homes, lead sedentary lifestyles, which reduces their life expectancy. Motion-based video games encourage physical activity and might be an opportunity for these adults to remain active and engaged; however, research efforts in the field have frequently focused on younger audiences and little is known about the requirements and benefits of motion-based games for elderly players. In this paper, we present an overview of motion-based video games and other interactive technologies for older adults. First, we summarize existing approaches towards the definition of motion-based video games – often referred to as exergames – and suggest a categorization of motion-based applications into active video games, exergames, and augmented sports. Second, we use this scheme to classify case studies addressing design efforts particularly directed towards older adults. Third, we analyze these case studies with a focus on potential target audiences, benefits, challenges in their deployment, and future design opportunities to investigate whether motion-based video games can be applied to encourage physical activity among older adults. In this context, special attention is paid to evaluation routines and their implications regarding the deployment of such games in the daily lives of older adults. The results show that many case studies examine isolated aspects of motion-based game design for older adults, and despite the broad range of issues in motion-based interaction for older adults covered by the sum of all research projects, there appears to be a disconnect between laboratory-based research and the deployment of motion-based video games in the daily lives of senior citizens. Our literature review suggests that despite research results suggesting various benefits of motion-based play for older adults, most work in the field of game design for senior citizens has focused on the implementation of accessible user interfaces, and that little is known about the long-term deployment of video games for this audience, which is a crucial step if these games are to be implemented in activity programs of senior residences, care homes, or in therapy

Guidelines for designing augmented reality games

The growing popularity of augmented reality (AR) games in both a research and more recently commercial context has led for a need to take a closer look at design related issues which impact on player experience. While issues relating to this area have been considered, to date most of the emphasis has been on the technology aspects. Furthermore it is almost always assumed that the augmented reality element in itself will provide a sufficient experience for the player. This has led to a need to evaluate what makes a successful augmented reality game. In this paper we present a set of design guidelines which are drawn from experiences of three mixed reality games. The guidelines provide specific guidance on relationships between real and virtual space, social interaction, use of AR technologies, maintaining consistent themes and implicitly address higher level aspects such as presence within a particular augmented reality place

Exploration Games:Can Game-Guided Systems Support Users in Automated Exhibition Sites?

This article delves into the potential of incorporating elements fromadventure games into museum exhibitions, with a particular focus on automatedexhibition sites. We advocate that principles derived from adventure games canadeptly bridge the two primary expectations of exhibitions: enlightenment andexperience. Exploration-based games, such as Explore the Redoubt (XTR)crafted for automated venues, enable users to fulfill both these objectives. XTR,conceived to address the prevailing research voids, integrates game mechanicsinto the automated exhibition environment, enhancing visitor motivation andengagement. It harnesses interactive digital mediums to present cultural heritagein a relaxed, informal manner.Existing research scarcely touches upon the design of experiential learninggames developed for automated sites, which encompass both indoor and outdoordisplays. Our methodology contemplates the transformation of visitor conduct atexhibitions, morphing them into avid knowledge seekers. We challenge theadequacy of current user experience models in portraying exhibitions striving toprovide both enlightenment and an immersive experience. Consequently, weintroduce a framework for museum interactions that deeply engages users, urgingthem to define their exploration trajectories, seamlessly fusing enlightenment,and engagement. Our study is set in a 17th-century redoubt where initialobservations indicated greater outdoor engagement compared to indoor spaces.This observation fueled our initiative to amplify indoor visitor participation.After testing XTR with 30 participants and employing a combination ofobservations and interviews, we derived key insights on designing digitalexploration games that seamlessly combine enlightenment and engagement. Weconclude with three design strategies to enhance visitor curiosity and exploration
