Several changes are caused by aging, among them, the higher prevalence of mood disorders, such as depression and anxiety. Some evidences have indicated positive effects of some types of exercise on reduction of depression and anxiety. The aims of the present study were: a) to evaluate the acute effects of exercise in the Xbox Kinect on the mood of the untrained elderly people; b) investigate possible correlations between the degree of enjoyment in the activity and improvement in mood. We selected twenty-nine elderly (15 men and 14 women), with age of 66,4 ± 0,8 years (mean ± standard error). The participants were evaluated in two conditions: Control Condition (CC), in which volunteers watched the film "The March of the Penguins" (60 minutes) and Experimental Condition (EC), which consisted of one session of exercise with the Xbox Kinect (60 minutes). The order of conditions was randomly defined. The mood state was evaluated in the pre and post-interventions using the POMS questionnaire (Profile of Mood States). The PACES Scale (Physical Activity Enjoyment Scale) was used to evaluate the degree of enjoyment. For both conditions, there was a significant reduction in the scores of tension-anxiety, depression and total mood disorder (p ≤ 0,05). There were not significant differences between the conditions for all studied variables. There was a significant negative correlation at the EC, between the percentage of enjoyment and the scores of tension-anxiety (r = -0.40), depression (r = -0.40) and total mood disorder (r = -0.49), evaluated by POMS (p ≤ 0,05). On the other hand, no significant correlations were found in the CC for the same variables. Thus, we could conclude that both activities promote improvements in mood state in untrained elderly, however, the effect sizes observed after CC were lower (smaller) those observed after EC (median), indicating most significant clinical effects in the EC. Moreover, higher enjoyment during the activity in the Xbox Kinect was associated with greater improvement in mood states. / O envelhecimento populacional é considerado um fenômeno de amplitude mundial. Diversas alterações são provocadas pelo envelhecimento, entre elas, o aumento da prevalência de transtornos do humor, como a depressão e a ansiedade. Evidências científicas demonstram efeito positivo de diversos tipos de exercício físico na redução desses sintomas. Os objetivos do presente estudo foram: a) avaliar o efeito agudo de atividades realizadas no Xbox Kinect sobre o estado de humor de idosos destreinados; b) verificar as possíveis relações entre o grau de diversão da atividade e a melhora no humor. Foram selecionados vinte e nove idosos (15 homens e 14 mulheres), com idade de 66,4 ± 0,8 anos (média ± erro padrão). Os participantes foram avaliados em duas condições: Condição Controle (CC), na qual os participantes assistiram ao filme “A Marcha dos Pinguins” (60 minutos) e Condição Experimental (CE), que consistiu em uma sessão de atividades no Xbox Kinect com duração de 60 minutos. A ordem das condições foi definida de forma aleatória. O estado de humor foi avaliado nos momentos de pré e pós-intervenções através da aplicação do questionário de POMS (Profile of Mood States). A Escala de PACES (Physical Activity Enjoyment Scale) foi utilizada para avaliar o grau de diversão das atividades. Para ambas as condições, houve uma redução significante dos escores de tensão-ansiedade, de depressão e do distúrbio total de humor (p ≤ 0,05). Não foram observadas diferenças significantes entre as condições nas variáveis estudadas. Houve uma significante correlação negativa, na CE, entre o percentual de diversão e os deltas dos escores de tensão-ansiedade (r= -0,40), depressão (r= -0,40) e o distúrbio total de humor (r= -0,49), avaliado pelo POMS (p ≤ 0,05). Por outro lado, não foram encontradas correlações significantes na CC, para as mesmas variáveis. Assim, pode-se concluir que a sessão aguda de atividade no Xbox Kinect, bem como a condição controle (filme) promoveram melhoras no estado de humor de idosos destreinados, no entanto, os tamanhos de efeito observados após a CC foram inferiores (pequenos) aos observados após a CE (médios), indicando efeitos clínicos mais significantes na CE. Além disso, quanto maior foi a diversão durante a atividade realizada no Xbox Kinect, maior foi a melhora no estado de humor.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product. The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed. / Detta examensarbete utfördes som uppdrag åt Ludosity Interactive där målet var att utveckla en kopia av Xbox Live Indie Games-marknadsplatsens gränssnittet från Xbox 360:n. Ludosity Interactive hade ett behov av att enkelt kunna testa ett spels attraktionskraft hos potentiella kunder med hjälp av utomstående testpersoner i en simulerad testmiljö; utöver detta systemet finns det inget sätt att kunna göra en sådan analys utan att släppa produkten på Xbox Live Indie Games-marknaden och sedan analysera försäljningen av produkten. Det färdiga systemet var tvunget att vara såpass snarlikt originalförlagan att en användare skulle kunna förbi se själva gränssnittet och använda det precis som de använder den riktiga marknadsplatsen. Det skulle också vara enkelt att kunna förändra och lägga spel i systemet så att som Ludosity Interactive lätt kan visa de spelen och den data de anser intressant för sina tester. Den färdiga produkten utvecklades med hjälp av C#, XNA och XML samt en Agile-inspirerad utvecklingsmetod i kombination med Pivotal Tracker. Denna rapport beskriver hur den produkten definierades och utvecklades.

Gaming consoles’ relevance to the field of digital forensics has steadily been growing sincetheir presence in society has increased. Given how gaming platforms, such as the Xbox One,are produced for commercial interest, they are likely to be secured by use of proprietaryknowledge to safeguard personal data. The means by which information is secured isunknown, thus displaying the need for investigations to determine what information can beextracted from hard drive disk images and whether any of it is personally identifiable data.Furthermore, predecessors to the Xbox One were successfully modified by users, allowingunsigned code to be run; however, this is currently not possible on the Xbox One. In addition,due to the generational aspect of game consoles, proper digital forensic methodology needs tobe developed specifically adapted to the Xbox One. An exploratory approach was pursued toallow for the scope to remain dynamic, letting information found to point to additionalavenues of investigation and research. No personally identifiable information was found, yetthe analysis of selected files allowed for hypotheses concerning their intended purpose.Through file analysis, encryption was found to be in use on the console. Moreover, theMaster File Table was demonstrated as a significant extension to the foundation of consoleforensics methodology. Lastly, it was established that the Xbox One successfully prevents therunning of unsigned code, showing a significant improvement compared to its predecessors.

Nedladdade spel har blivit mer förekommande än vad de var för ett årtionde sedan. Bredbandets framgång har gjort det möjligt att snabbt ladda ner spel och marknaden för digitala spel växer stadigt. I denna studie undersöker vi om konsolspelarnas attityd mot digitala konsolspel skiljer sig från fysiska konsolspel i och med den växande digitala marknaden. Vi presenterar och diskuterar konsolspelares attityd mot digitala och fysiska spel och deras uppfattade värde av dessa format. I de kvantitativa undersökningar som vi utförde visar vi att människor föredrar fysiska konsolspel framför digitala, även fast den digitala marknaden är på stadig uppgång. Baserat på de resultat i vår studie så fann vi att den mest förekommande anledningen till att fysiska konsolspel föredrogs var de möjligheter som fysiska kopior medför, såsom att kunna sälja, byta, visa upp eller återlämna sitt spel. / Downloadable games are more common these days than they were a decade ago. The prowess of broadband has made it possible to quickly download games and the market for digital games is growing steady. In this paper we study if the attitude towards digital console games differentiates from physical console games due to the growing digital market. We present and discuss console users’ attitude towards digital and physical games and their perceived value. From the quantitative studies performed we show that people prefer physical console games over digital, even though the digital market is on a steady climb. Based on the results we found the most common cause for the preference of physical copies was the possibilities the physical format entailed, such as trad- ing, exhibiting, refunding or borrowing.

Games in general and computer games in particular have now become a mainstream activity for young people in the industrialized nations. Sadly, people’s interaction with computer artifacts and games are mainly still limited to the visual and auditive modalities. This constrains the richness of our interaction with those artifacts, it constrains the possibilities of using those artifacts to communicate and build relations with others, and it excludes some people from using them at all. This thesis answers the questions of whether it’s possible to use haptics as a single modality for conveying information in computer games, if it’s possible to translate the standard interfaces of existing computer games into haptic interfaces, and if it can be accomplished with the technology used in the gamepads of current generation game consoles. It also contains a theoretical foundation for using haptics in game design and a new design method for analyzing the requirements of computer game interface modalities. A computer game prototype called Sightlence was developed in order to answer these questions. The prototype was developed in four iterative cycles of design, development, and evaluative play sessions. Four groups of people participated in the play sessions: graduate students, and teachers, specializing in games; people who are deafblind; people from the general population; and pupils from a national special needs school in Sweden for children with deafness or impaired hearing combined with severe learning disabilities, or congenital deafblindness. The prototypes were tested with usability techniques for measuring performance and learnability. The usability tests showed that Sightlence can be successfully learned by people from the general population while the pupils with cognitive development disorders from the special needs school would need additional support in the game in order to learn to handle the increased abstraction caused by the haptic interface. The thesis ends with discussion of the designed and developed artifact Sightlence. The discussion touches on the design process, the usability testing, and possible future research and development relevant for making haptics a fruitful tool and medium for designers and people.
