Classic Nintendo games are (computationally) hard

We prove NP-hardness results for five of Nintendo's largest video game franchises: Mario, Donkey Kong, Legend of Zelda, Metroid, and Pokémon. Our results apply to generalized versions of Super Mario Bros.1-3, The Lost Levels, and Super Mario World; Donkey Kong Country 1-3; all Legend of Zelda games; all Metroid games; and all Pokémon role-playing games. In addition, we prove PSPACE-completeness of the Donkey Kong Country games and several Legend of Zelda games.

The contribution of upper limb and total body movement to adolescents’ energy expenditure whilst playing Nintendo Wii

Little research documents the contribution of upper limb and total body movement to energy expenditure (EE) during active video gaming. To address this, EE, heart rate (HR), and, upper limb and total body movement were assessed in 11- to 17-year-old adolescents whilst playing three active (Nintendo Wii) and one sedentary (XBOX 360) video games. Non-dominant upper limb activity, EE and HR were significantly greater during Wii Sports boxing [mean 267.2 (SD 115.8) J kg−1 min−1; 136.7 (24.5) beats min−1] than tennis or bowling (P ≤ 0.044). For all active games hip activity best predicted EE (R 2 ≥ 0.53), with two-measure models of HR and single-site activity data, and multi-site activity data, similarly explaining the variance in EE (R 2 ≥ 0.64). The physiological cost of upper-body orientated active video games increased when movement of both upper limbs was encouraged. Improvements in EE explanatory power provide support for multi-site activity monitoring during unique, non-ambulatory activities.

Effect of Nintendo Wii (TM)-based motor and cognitive training on activities of daily living in patients with Parkinson's disease: A randomised clinical trial

Objectives To investigate the effect of Nintendo Wii (TM)-based motor cognitive training versus balance exercise therapy on activities of daily living in patients with Parkinson's disease. Design Parallel, prospective, single-blind, randomised clinical trial. Setting Brazilian Parkinson Association. Participants Thirty-two patients with Parkinson's disease (Hoehn and Yahr stages 1 and 2). Interventions Fourteen training sessions consisting of 30 minutes of stretching, strengthening and axial mobility exercises, plus 30 minutes of balance training. The control group performed balance exercises without feedback or cognitive stimulation, and the experimental group performed 10 Wii Fit (TM) games. Main outcome measure Section II of the Unified Parkinson's Disease Rating Scale (UPDRS-II). Randomisation Participants were randomised into a control group (n = 16) and an experimental group (n = 16) through blinded drawing of names. Statistical analysis Repeated-measures analysis of variance (RM-ANOVA). Results Both groups showed improvement in the UPDRS-II with assessment effect (RM-ANOVA P < 0.001, observed power = 0.999). There was no difference between the control group and the experimental group before training {8.9 [standard deviation (SD) 2.9] vs 10.1 (SD 3.8)}, after training [7.6 (SD 2.9) vs 8.1 (SD 3.5)] or 60 days after training [8.1 (SD 3.2) vs 8.3 (SD 3.6)]. The mean difference of the whole group between before training and after training was -0.9 (SD 2.3, 95% confidence interval -1.7 to -0.6). Conclusion Patients with Parkinson's disease showed improved performance in activities of daily living after 14 sessions of balance training, with no additional advantages associated with the Wii-based motor and cognitive training.

Motor learning, retention and transfer after virtual-reality-based training in Parkinson's disease - effect of motor and cognitive demands of games: a longitudinal, controlled clinical study

Objectives To evaluate the learning, retention and transfer of performance improvements after Nintendo Wii Fit (TM) training in patients with Parkinson's disease and healthy elderly people. Design Longitudinal, controlled clinical study. Participants Sixteen patients with early-stage Parkinson's disease and 11 healthy elderly people. Interventions Warm-up exercises and Wii Fit training that involved training motor (shifts centre of gravity and step alternation) and cognitive skills. A follow-up evaluative Wii Fit session was held 60 days after the end of training. Participants performed a functional reach test before and after training as a measure of learning transfer. Main outcome measures Learning and retention were determined based on the scores of 10 Wii Fit games over eight sessions. Transfer of learning was assessed after training using the functional reach test. Results Patients with Parkinson's disease showed no deficit in learning or retention on seven of the 10 games, despite showing poorer performance on five games compared with the healthy elderly group. Patients with Parkinson's disease showed marked learning deficits on three other games, independent of poorer initial performance. This deficit appears to be associated with cognitive demands of the games which require decision-making, response inhibition, divided attention and working memory. Finally, patients with Parkinson's disease were able to transfer motor ability trained on the games to a similar untrained task. Conclusions The ability of patients with Parkinson's disease to learn, retain and transfer performance improvements after training on the Nintendo Wii Fit depends largely on the demands, particularly cognitive demands, of the games involved, reiterating the importance of game selection for rehabilitation purposes.

Da fantasia à realidade, da realidade à fantasia: aspectos culturais, históricos e mercadológicos das campanhas publicitárias de games

A pesquisa tem como objetivo geral compreender como as empresas fabricantes de consoles de videogames da última geração (Sony, Microsoft e Nintendo) utilizam a publicidade para atingir os consumidores. O corpus de análise e interpretação delimita-se em oito peças publicitárias audiovisuais e o período de análise é de 2010 a 2011. As estratégicas metodológicas utilizadas são: quanto aos dados de pesquisa, o estudo é essencialmente qualitativo; em relação aos objetivos, a pesquisa é exploratória; quanto às fontes para obtenção de dados, a pesquisa é bibliográfica e empírica, sendo a fase empírica dividida em observação não-participante, descrição dos anúncios de games e análise de conteúdo audiovisual. Após as análises, demonstrou-se que, apesar de os games estarem na vida cotidiana e serem sonho de consumo de muitas pessoas, sua divulgação ainda é restrita a um número limitado de jogadores. Observa-se que, nas campanhas analisadas como um conjunto, há uma preocupação maior com o público adulto, o que não ocorria há cinco anos, na geração anterior de consoles. Apesar disso, os consoles ainda não são enxergados com todas as suas potencialidades tecnológicas e culturais.

"Games are fun and aren't just for boys": an assessment of female game players use and playing habits of video games

Video games have asserted themselves as a prevalent part of society; however video games are still often seen as 'boys toys'. However, popular culture is becoming accepting that video games are played by females, with 'all female' video games teams such as the 'Frag Dolls' winning many international competitions [4]. The gender issue in video games is not a new topic, with texts such as 'From Barbie to Mortal Combat' edited by Cassell and Jenkins being publishing in 1998. However, the question of 'do females actually play video games' is still apparent, and with the rapid changes in technological development in gaming (with the introduction of consoles such as the Nintendo Wii) the subject of females game playing habits is in need of constant dialogue. This paper explores the results from a survey of 33 Australian females who play video games and looks at the game playing habits and choices made when they play video games. In addition, this study will attempt to address what components of video games make females want to play. It is hoped that the results can enlighten our knowledge of why females play video games, and hopefully assert the need for video games as an important pastime for females and not just 'for the boys'.

Playing with other(ed) species: games, representation, and nonhuman animals

During the writing of this essay, the controversial nonhuman animal rights organisation PETA (People for the Ethical Treatment of Animals) sent out a tweet linking to an online article about the recent PC and Playstation 4 console game No Man’s Sky, in which players are positioned as explorers of countless virtual planets. Encountering the wide array of creatures indigenous to these worlds, players of this game are offered the choice of whether ‘to document them and name them or slaughter them en masse’ (Francisco, ‘PETA’). While an environmental agenda appears to be far from the game designers’ minds, PETA’s Marketing Vice President Joel Bartlett interprets No Man’s Sky as ‘counting on our natural empathy … we have a natural sense of exploration that has been important to human history’ (Francisco, ‘PETA’). Indeed, PETA has immersed itself in the gaming industry by creating its own simple online games in-house, such as the provocative Mario Kills Tanooki, which opposes what it sees as the unethical messages conveyed by Nintendo’s popular Super Mario Bros. franchise. These instances of the intersection of exploration, ethics, empathy, and play raise important questions regarding the potential role(s) of gaming in furthering (or hindering) the welfare of nonhuman animals. This issue becomes more and more urgent not only in a time of ongoing climate change, environmental degradation, and the continued endangerment of countless species around the planet, but also in a time when the gaming industry and the adoption of game design principles in many others grows apace.

Now everything looks like a game : Mobile phones and location-based games.

This paper explores how we may transform peoples’ perceived access to cultural participation by exploiting the possible relationships between place, play and mobile devices. It presents SCOOT; a location-based game in order to investigate how aspects of game-play can be employed to evoke at once playful and culturally meaningful experiences of place. In particular this paper is concerned with how the portable, communicative and social affordances of mobile phones are integral to making a “now everything looks like a game” experience.

Maintaining human agency in the design on context-aware systems : Design games in a dental surgery

This paper describes a series of design games, specifically aimed at exploring shifts in human agency in order to inform the design of context-aware applications. The games focused on understanding information handling issues in dental practice with participants from a university dental school playing an active role in the activities. Participatory design activities help participants to reveal potential implicit technical resources that can be presented explicitly in technologies in order to assist humans in managing their interactions with and amidst technical systems gracefully.

Co-creating games: A co-evolutionary analysis

ABSTRACT. The phenomenon of consumer co-creation is often framed in terms of whether either economic market forces or socio-cultural non-market forces ultimately dominate. We propose an alternate model of consumer co-creation in terms of co-evolution between markets and non-markets. Our model is based on a recent ethnographic study of a massively multiplayer online game through its development, release and ultimate failure, and cast in terms of two explanatory models: multiple games and social network markets. We conclude that consumer co-creation is indeed complex, but in ways that relate to both emergent market expectations and the evolution of markets, not to the transcendence of markets.
