Serious interface design for dental health: Wiimote-based tangible interaction for school children

This paper describes a camera-based approach towards creating a tangible interface for serious games. We introduce our game for dental health targeted at school children which implements the Nintendo WiiMote as infrared camera. Paired with a gesture-recognition system, this combination allows us to apply real-world items as input devices. Thereby, the game tries to address different aspects of dental hygiene along with the improvement of children's motor skills. In our focus group test, we found that tangible interfaces offer great potential for educational purposes and can be used to engage kids in a playful learning process by addressing their childlike curiosity and fostering implicit learning

Designing and evaluating digital games for frail elderly persons

Game research increasingly addresses human factors of gaming. Though more and more seniors become players, game design for frail elderly has rarely been explored. This paper addresses game design for senior citizens experiencing age-related changes, especially cognitive and physical limitations. We introduce and evaluate the case study SilverPromenade, which is specifically aimed at providing institutionalized frail elderly with a new leisure activity. SilverPromenade allows players to go on virtual walks while accounting for special needs regarding game complexity, and simplistic interaction paradigms are provided using Nintendo's Wii Remote and the Balance Board for game control. Evaluation results suggest that despite age-related impairments, the game was generally accessible to elderly persons. Yet, differences between inexperienced and experienced players were observed which suggest that interaction problems may be reduced by engaging with games over a longer time. Findings also indicate that the engagement of elderly players transcends into their everyday life, and their social interaction increases among one another. Most importantly, the evaluation showed that games were perceived as enjoyable leisure activity, supporting the approach of applying digital games to raise the quality of life among frail elderly by fostering activity.

Brief history of serious games

Serious Games are now an established field of study. In this field most would attribute the rise of Serious Games to Clark C Abt’s creation of the term in 1970, or indeed Ben Sawyer’s popularization of it in 2002. However, considering the rich history of purposing non-digital games, itself preceded by discussions of purposing play that are traceable to the work of Plato, it can be said that Serious Games is a contemporary manifestation of centuries old theories and practices. In this chapter, we explore the pre-history of Serious Games, beginning with the suggested purpose, and purposing of play. Throughout this historical review we identify key in research and practice that are apparent in the contemporary Serious Games field

M3 money demand and excess liquidity in the euro area

Recent empirical studies have found evidence of unstable long run money demand functions if recent data are used. If the link between money balances and the macroeconomy is fragile, the rationale of monetary aggregates in the ECB strategy has to be doubted. In contrast we present a ``stable'' long run money demand relationship for M3 for the period 1983-2006. To obtain the result, the short run homogeneity restriction between money and prices is relaxed and a break in the income elasticity of money demand after 2001 is taken into account. Measures of excess liquidity do not show significant inflation pressures.The final publication is available at Springer via http://dx.doi.org/10.1007/s11127-010-9679-5.
