This dissertation examines the impact of playing video games on social relationships. The main goal of the research is to find out how relationships differ between gamers and non-gamers. The quality of relationships is examined via Furman's and Buhrmester's Network of relationship inventory. The values are compared according to the gaming status. Apart from the basic groups I compared some other groups such as online and offline gamers, men and women or gamers who prefer playing alone and players who play with their friends. According to the inventory findings the relationship qualities of gamers and non-gamers do not differ significantly. Comparison of some other groups brought some interesting relationship differences among groups of men and women and, also, a correlation between the increasing average game time and decreasing quality of relationship with family members was observed.

No presente trabalho, é testada e avaliada a aplicação de Redes Neurais Artificiais no combate de trapaças (cheating, em inglês) do tipo speed cheating em jogos online massivos de múltiplos jogadores, também conhecidos como MMOG (Massively Multi- player Online Games). Os MMOG representam um modelo de negócio onde quantias significativas de recursos financeiros estão envolvidas, e crescem a cada dia. Os mode- los para o combate de trapaças, que possam afastar jogadores de jogos ou servidores, estão localizados na camada de rede, à nível de protocolo. Analisando o estado-da-arte, constatou-se que não existem trabalhos explorando a área de Inteligência Artificial para este fim, tornando-se assim relevante o estudo de sua aplicabilidade. As Redes Neurais Artificiais foram escolhidas por terem grande poder de abstração, generalização e plasti- cidade. Através dos resultados obtidos comparando-se duas abordagens de arquiteturas, as redes Perceptron de múltiplas camadas (MLP) e as redes com atraso no tempo focadas (FTLFN), é possível constatar que é viável a utilização das mesmas para este fim, tendo-se alcançado resultados positivos no combate de speed cheating em MMOGs. / In the present work, Artificial Neural Networks are tested and evaluated in order to avoid a specific type of cheating, called Speed Cheating, in massively multi-player online games (MMOG). The MMOG represent a business model where meaningful financial resources amounts are involved, and increase each day. The models to avoid cheating, that could keep off players from games and servers, are localized in the network layer, at the protocol level. Examining the state-of-art, it was observed that research explor- ing the Artificial Intelligence application to this goal becomes relevant. The Artificial Neural Networks were chosen by their significant abstraction, generalization and plas- ticity characteristics. Through the results’s comparison from two different architectures approaches, the multi layer Perceptron network (MLP) and the focused time lagged net- work (FTLFN), it was possible to conclude that their utilization avoiding speed cheating in MMOG is possible, once good results were found in this work.

Developing video games is an iterative and demanding process. It is difficult to achieve the goal of most video games — to be enjoyable, engaging and to create revenue for game developers — because of many hard-to-evaluate factors, such as the different ways players can interact with the game. Understanding how players behave during gameplay is of vital importance to developers and can be uncovered in user tests as part of game development. This can help developers to identify and resolve any potential problem areas before release, leading to a better player experience and possibly higher game review scores and sales. However, traditional user testing methods were developed for function and efficiency oriented applications. Hence, many traditional user testing methods cannot be applied in the same way for video game evaluation. This thesis presents an investigation into the contributions of physiological measurements in user testing within games user research (GUR). GUR specifically studies the interaction between a game and users (players) with the aim to provide feedback for developers to help them to optimise the game design of their title. An evaluation technique called Biometric Storyboards is developed, which visualises the relationships between game events, player feedback and changes in a player's physiological state. Biometric Storyboards contributes to the field of human-computer interaction and GUR in three important areas: (1) visualising mixedmeasures of player experience, (2) deconstructing game design by analysing game events and pace, (3) incremental improvement of classic user research techniques (such as interviews and physiological measurements). These contributions are described in practical case studies, interviews with game developers and laboratory experiments. The results show this evaluation approach can enable games user researchers to increase the plausibility and persuasiveness of their reports and facilitate developers to better deliver their design goals. Biometric Storyboards is not aimed at replacing existing methods, but to extend them with mixed methods visualisations, to provide powerful tools for games user researchers and developers to better understand and communicate player needs, interactions and experiences. The contributions of this thesis are directly applicable for user researchers and game developers, as well as for researchers in user experience evaluation in entertainment systems.

本論文重新探討自我調節的情緒管理(self regulation of emotion regulation)並提出個人能夠因應自己的實際情緒 (actual affect) 而把其反饋和調節至接近理想的情緒 (ideal affect)上。 / 為了解自我調節的情緒管理所涉及的過程以及其影響，我隨機安排94位香港的女大學生處於緊張(高激發負面/ high arousal negative)或者悶氣(低激發負面/low arousal negative)的情景當中，隨後邀請她們選擇高激發正面(high arousal positive) 或者低激發正面(low arousal positive)的產品，以及試玩她們所選擇的電子遊戲來調節管理之前受影響的情緒。結果顯示：參加者比較偏向選擇低激發正面的產品。同時，參加者完成任何一種電子遊戲也降低了之前所受的負面情緒。曾處於緊張情景的參加者在玩後增加冷靜；而曾處於悶氣情景的參加者在玩後則減少冷靜。是次研究的結果支持上面提出的說法，即是：當人自我調節和管理情緒時，人能夠縮短實際情緒和理想情緒之間的差距從而管理負面的情緒。 / This study reviewed the literature in self regulation of emotion and suggested that individuals would modulate negative actual affect to turn it into positive ideal affect. To examine emotion regulatory mechanisms and outcomes, 94 Hong Kong female Chinese undergraduates were randomly assigned to either nervousness (high arousal negative) or boredom (low arousal negative) conditions. Next, they selected either high arousal positive (HAP) or low arousal positive (LAP) products in decision making tasks. Based on their selection, they then played HAP or LAP video game to perform emotion regulatory tasks. Although participants chose LAP over HAP products, participants decreased induced negative affect after playing the selected video game. Also, participants from the nervousness condition increased low arousal positive affect in calmness and those from boredom condition decreased it. Current findings suggested that individuals minimized the discrepancy between actual and ideal affect to regulate negative emotions. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Ho, Yuen Wan. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 37-41). / Abstracts also in Chinese. / Acknowledgement --- p.i / Abstract (English) --- p.ii / Abstract (Chinese) --- p.iii / Table of Contents --- p.iv / List of Tables --- p.vi / Chapter Chapter 1 --- : Introduction --- p.1 / Emotion Regulation: A Consensual Process Model --- p.1 / Emotion in Self Regulation and Self Regulation of Emotion --- p.3 / Emotion Regulation: Processes of Interaction between Actual and Ideal Affect --- p.4 / My Present Study --- p.9 / Chapter Chapter 2 --- : Method --- p.13 / Participants --- p.13 / Materials --- p.13 / Affect Induction Tasks --- p.13 / Product Decision Making Tasks --- p.14 / Product Testing Tasks --- p.15 / Measures and Procedures --- p.16 / Chapter Chapter 3 --- : Results --- p.22 / Actual and Ideal Affect before affect induction tasks --- p.22 / Manipulation of Nervousness and Boredom --- p.22 / Individual Product and Activity Preferences in Product Decision Making Tasks --- p.25 / Actual Affect in and after Product Testing Tasks --- p.26 / Chapter Chapter 4 --- : Discussion --- p.31 / References --- p.37 / Appendix --- p.42 / Chapter I --- Consumer Preferences Questionnaire --- p.42 / Chapter II --- Game Evaluation Questionnaire --- p.43 / Chapter III --- Suspicion Questionnaire --- p.44

The changes on sleep patterns may influence the different cognitive processes performance. Many recent studies show the possibility of cognitive performance improvement, through the cognitive training with the use of computer games. The question is if these interventions may be influenced by the sleep quality. Thus, we evaluated the sleep quality effect about the efficacy of an intervention with computers games based on the working memory and attention for a cognitive performance training of elementary school students. The sample was constituted by 42 students with average age of 10,43 years old (SD=1,23), with 22 male participants and 20 female participants. We used to evaluate the sleep with the parents a sleep questionnaire, a sleep diary and the Sleep Behavior Questionnaire. In regard to intervention, the subjectives were distributed in an experimental and in a control group, both with 21 participants. In the first group occurred the intervention that consisted in the working memory and attention training with two cognitive tasks (Safari e Brain Workshop) during 30 daily minutes, for a 6 weeks period. In an equal period, the students from the control group should reproduce an artwork using drawing software. To evaluate the cognitive performance we applied before and after the intervention period the Wechsler Intelligence Scale for Children (WISC-III). The results showed that in both the groups the performance of the intelligence, working memory, attention and visuospatial skills was below of the mean. The cognitive processes evaluated after of intervention in the experimental group had a performance significantly higher in the Perceptual Reasoning Index (t = -6,24; p < 0,01) and in the Full Scale IQ (t = -5,09; p < 0,01) and Performance IQ (t = -6,52; p < 0,01), suggesting a improvement on the visuospatial skills, attention, working memory and processing speed. On the control group, the performance was significantly higher in the Coding subtest (t = -5,38; p< 0,01) and in the Perceptual Reasoning Index (t = -3,66; p = 0,01), suggesting a improvement on the visuospatial skills and attention. The mean obtained with the Sleep Behavior Questionnaire was 53,76 (SD=14,96) for an experimental group and 61,19 (SD=12,82) for a control group, indicating tendency for a bad sleep quality in that last one. Not only during the first days, but also in the last fifteen days of the intervention we verified in the two groups an adequate time to sleep, duration and regularity, in the weekdays and on the weekends. We didn t find significant differences between the two groups in none of the sleep variables. We verified statistically meaningful improvement on the performance of the experimental group with the intervention in the two games. We didn t verify significant correlations between the games performance index and in the sleep variables of the experimental group individuals. We verified significant correlations among the performance on the Brain Workshop and the Cubes subtest, the Perceptual Reasoning Index and the Scale Performance IQ, suggesting that the significant improvement of the visuospatial skills and of the attention was correlated with the performance in the Brain Workshop. Although the absence of correlations with the performance in the Safari, possibly it also has relieved in the improvement of the cognitive performance. The findings support the hypothesis that the computer games might be a satisfactory tool for the improvement of the performance in visuospatial skills and attention. This can be resulted of the insertion of visuospatial stimulations in the task, for example, graphical elements with thematic for children that increase the interest. The IQ below mean the individuals might have influenced the improvement absence on the cognitive processes like the working memory with games. Moreover, it wasn t verified a relation between the sleep quality and the intervention efficacy. It might have been influenced by the n of the sample. Future studies must focalize in the improvement of the effect of the interventions with games / O sono ? um processo cerebral ativo que contribui para a realiza??o eficiente das tarefas cotidianas. Mudan?as em seu padr?o podem influenciar o desempenho de diversos processos cognitivos. V?rios estudos recentes t?m demonstrado a possibilidade de melhora do desempenho cognitivo, a partir do treinamento cognitivo com o uso de jogos de computador. A quest?o ? se tais interven??es podem ser influenciadas tamb?m pela qualidade do sono. Assim, avaliamos o efeito da qualidade do sono sobre a efic?cia de uma interven??o com jogos de computador baseada no treinamento da mem?ria operacional e da aten??o para o desempenho cognitivo de alunos do ensino fundamental. A amostra foi constitu?da por 42 alunos com idade m?dia de 10,43 (DP=1,23) anos, sendo 22 indiv?duos do sexo masculino e 20 do feminino. Utilizamos para a avalia??o do sono junto aos pais uma ficha sobre sono, um di?rio do sono e o Question?rio sobre Comportamento do Sono. Para a interven??o, os indiv?duos foram alocados nos grupos experimental e controle, ambos com 21 indiv?duos. No primeiro grupo ocorreu a interven??o, que consistiu no treinamento da mem?ria operacional e da aten??o com duas tarefas cognitivas (Safari e Brain Workshop) por 30 minutos di?rios, por um per?odo de 6 semanas. Por igual per?odo, os indiv?duos do grupo controle deveriam reproduzir uma obra de arte utilizando software de desenho. Para avalia??o do desempenho cognitivo aplicamos antes e depois do per?odo de interven??o a Escala de Intelig?ncia Wechsler para Crian?as (WISC-III). Os resultados mostraram que em ambos os grupos o desempenho da intelig?ncia, mem?ria operacional, aten??o e visuoespacialidade foi abaixo da m?dia esperada. Os processos cognitivos avaliados ap?s a interven??o no grupo experimental tiveram um desempenho significativamente maior no ?ndice Organiza??o Perceptual (t = -6,24; p < 0,01) e nas escalas de QI Total (t = -5,09; p < 0,01) e de QI de Execu??o (t = -6,52; p < 0,01), sugerindo melhora na performance da visuoespacialidade, aten??o e velocidade de processamento. No grupo controle, o desempenho foi maior no subteste C?digo (t = -5,38; p < 0,01) e no ?ndice Organiza??o Perceptual (t = -3,66; p = 0,01), sugerindo melhora na performance da visuoespacialidade e aten??o. A m?dia obtida com o Question?rio de Comportamento do Sono foi de 53,76 (DP=14,96) para o grupo experimental e 61,19 (DP=12,82) para o grupo controle, indicando tend?ncia para qualidade do sono ruim nesse ?ltimo. Tanto nos primeiros como nos ?ltimos quinze dias da interven??o constatamos nos grupos hor?rios de dormir, dura??o e regularidade adequados, nos dias escolares e nos fins de semana. N?o verificamos diferen?as significativas entre os dois grupos em nenhuma das vari?veis de sono. Verificamos melhora significativa no desempenho do grupo experimental com a interven??o nos dois jogos. N?o verificamos correla??es significativas entre os ?ndices de desempenho dos jogos e as vari?veis de sono no grupo experimental. Verificamos correla??es significativas entre o desempenho no Brain Workshop e o subteste Cubos, o ?ndice Organiza??o Perceptual e a Escala de QI de Execu??o, sugerindo que a melhora significativa da visuoespacialidade e da aten??o estava correlacionada ao desempenho no Brain Workshop. Apesar da aus?ncia de correla??es com o desempenho no Safari, ? poss?vel que ele tamb?m tenha auxiliado na melhora da performance cognitiva. Os achados ap?iam a hip?tese de que os jogos de computador podem ser uma ferramenta satisfat?ria para a melhora do desempenho em visuoespacialidade e aten??o. Isso pode ser resultado da inser??o de est?mulos visuoespaciais na tarefa como, por exemplo, elementos gr?ficos com tem?ticas infantis que aumentam o interesse. O QI abaixo da m?dia dos indiv?duos pode ter interferido para que processos cognitivos como a mem?ria operacional n?o tenham melhorado com a interven??o. Al?m disso, n?o foi verificada rela??o entre a qualidade do sono e a efic?cia da interven??o, o que pode ter sido influenciado pelo n da amostra. Estudos futuros dever?o focar na otimiza??o dos efeitos das interven??es com jogos

Os jogos eletrônicos denominados Massive Multiplayer Online, nos quais milhares de pessoas podem estar conectadas simultaneamente, são tomados como exemplo atual de jogos coletivos. A partir da análise biopolítica de Michel Foucault, são investigadas as construções identitárias individuais, os papéis sociais e compromissos assumidos com outros jogadores e as aprendizagens e disciplinas reforçadas em tais jogos, tomando como referência o jogo World of Warcraft, o mais popular do gênero, atualmente. O trabalho de campo foi realizado com jogadores e com os websites oficiais do jogo selecionado, por onde circulam os regimes de verdades que aqui nos interessam. A cibercultura é compreendida, neste trabalho, como condição da engenharia social que reconfigura as distâncias e limites físicos e temporais, reforçando modos de sujeição sempre mais individualizados e referenciados por discursos de agrupamentos espraiados. O tipo de jogo analisado neste trabalho, além de tornar-se popular por empregar instrumentos e práticas próprias das novas tecnologias eletrônicas, favorece a análise de que as formas de governo e de controle sobre a vida estejam cada vez mais apuradas, transbordando por todos os planos da existência. Tal análise possibilita a problematização de discursos científicos, principalmente na última década, a respeito das práticas entre sujeitos, envolvendo jogos eletrônicos, e principalmente quando se referem às práticas em educação e aprendizagem. / The segment of computer games called Massively Multiplayer Online, in which thousands of people can be connected simultaneously, are taken as examples of current collective games. From the analysis of Michel Foucault\'s biopolitics, are investigated the identity constructions of individuals, social roles and commitments with other players and the learning and disciplines reinforced in such games, with reference to the game World of Warcraft, the most popular of this genre, today. The fieldwork was carried out with players and with the official websites of the selected game, through which the regimes of truths that concern us here. Cyberculture is understood in this work as a condition of social engineering that reconfigures the distances and the physical and temporal boundaries, reinforcing ways of subjection ever more individualized and referenced by speeches of sprawling groups. The type of game considered in this work, in addition to become popular by employing tools and practices peculiar to the new electronic technologies, favors the analysis that the forms of government and control over life are increasingly refined, overflowing by all planes of existence. Such analysis allows the questioning of scientific discourse, mainly in the last decade, about practices among subjects involving games, and mainly when referring to practices in education and learning.

Experimentos que investigam relações empíricas entre comportamento verbal e não verbal têm, em geral, manipulado tanto as descrições de contingências e observado seus efeitos sobre a resposta na contingência em vigor, como manipulado as contingências em vigor e observado os efeitos sobre as descrições das contingências. Estas pesquisas comparam os procedimentos de modelagem e instrução verbal, discutindo suas respectivas eficácias em serem acompanhados pelo comportamento não verbal correspondente. Uma forma alternativa de manipulação de antecedentes verbais, recentemente empregada com sucesso, é a modelagem de descrições de uma contingência que opera sobre o comportamento (frase qualificadora da atividade alvo) em vez da modelagem da descrição do comportamento alvo. O presente estudo testou a generalidade dos procedimentos de modelagem de frases qualificadoras e de instruções sobre a escolha de modalidades esportivas em um jogo de videogame. Quatro modalidades esportivas estavam disponíveis em sessões de livre escolha de jogo e de fotografias, dispostas antes da modelagem da escolha de frases. A modalidade menos escolhida, nas sessões de jogo em linha de base, definiu o critério da modelagem verbal para cada participante, tornando-se a modalidade alvo. Quatro frases qualificadoras compunham cada tentativa da modelagem verbal e a modalidade alvo, quando escolhida, era seguida de pontos. Atingido o critério de 100% de acerto na modalidade alvo em uma única sessão, sessões de livre escolha de jogo e de fotografias testaram os efeitos da modelagem verbal. Das oito crianças submetidas ao procedimento, apenas uma apresentou aumento no tempo despendido na modalidade alvo. Quatro participantes cuja modelagem não foi acompanhada do comportamento de jogo na modalidade alvo foram instruídos a jogar a modalidade alvo. Nestas condições, os resultados apontam para uma eficácia maior da instrução do que da modelagem em ser acompanhada pelo comportamento não verbal correspondente. A distribuição da escolha de fotos foi alterada, após as sessões de modelagem verbal, para seis dos oito participantes. Os resultados foram discutidos de acordo com o conceito de controle de estímulos aplicado a comportamentos governados verbalmente e categorizados em três tipos de controle, a saber, efeitos nulos, precisos e indeléveis do comportamento verbal modelado e instruído / The present study evaluated the effects of shaping a response class (differential reinforcement for the choice of qualifying phrases related to sports modalities) upon another class (the choice of the sports modalities in a videogame). Four sports modalities were available in free choice sessions that displayed games and photographs before the choice for the phrase shaping. The least chosen modality on the baseline game sessions defined the verbal shaping criterion for each participant, becoming the target modality. Four qualifying phrases made up each attempt of verbal shaping. When the target modality was chosen, points were delivered. When 100 per cent of the choices made were successful en relation to the target modality, free choice sessions of games and photographs tested the shaping effects. From the eight children who were submitted to the procedure only one presented an increase on the time spent on the target modality. Four participants whose shaping was not followed by the game behavior on the target modality were instructed to play on the target modality. Under these conditions, the results point to a higher efficacy of instructions in opposition to verbal shaping in terms of being followed by the corresponding non-verbal behavior. The arrangement of the photographs chosen was modified after the verbal shaping sessions for six out of the eight participants. The results were discussed according to the stimulus control concept applied to verbally governed behaviors classified according to three types of control, namely: null, transitory and marking effects of the shaped and instructed verbal behavior

Com o desenvolvimento da indústria de jogos computacionais, cresceu também o custo de produção destes jogos, a cada dia mais complexos, inviabilizando sua construção a partir do ?nada?. Isto fez com que as empresas de jogos passassem a desenvolver ou adquirir soluções reutilizáveis. Nesse trabalho, realizou-se um estudo sobre o emprego de reuso em jogos e, como conclusão, apresenta-se a forma como os padrões de projeto (design patterns) podem contribuir para o projeto da arquitetura de jogos computacionais, enfocando o desenvolvimento do núcleo de software que os compõe, denominado motor de jogo ou game engine. Para facilitar a manutenção e evolução do sistema, este componente deve apresentar as características de ser modular e extensível, além de algumas outras propriedades discutidas ao longo do texto. Apresenta-se o que é um motor de jogo e quais os módulos que o compõem, descrevendo-se, em seguida, os padrões de projeto e suas aplicações. Como experimento, analisa-se o uso de padrões de projeto por motores de jogo, utilizando-se, para isso, os que possuem código aberto ou que estão disponíveis na literatura, dando-se ênfase à abstração da API gráfica e observando-se os aspectos positivos e negativos de cada solução. Com base nessa análise, propõe-se uma solução que visa atender aos requisitos considerados relevantes para um motor do jogo. / The development of computer games industry increased the costs of production of these games, that every day are more complex, and made almost impracticable their construction from the beginning. As a result, those companies started to develop or acquire reusable solutions. This study shows the application of reuse in games and, as a conclusion, it demonstrates how design patterns can contribute in a project of computer games, focusing on the development of the software core that composes them, called game engine. In order to facilitate the maintenance and evolution of the system, this device should be modular and extensible, beyond other characteristics discussed in this text. It is also presented the definition of a game engine, specifying the modules that compile it, describing, after that, the design patterns and their applications. As an experiment, it is analyzed the use of design patterns in already existing game engines, making use of the ones that are open source or that are available in the literature. In this experiment, it is emphasized the abstraction of the graphical API, pointing out the positive and negative aspects of each solution. Based on this analysis, it is proposed a solution which aims to fulfill the requirements considered relevant in a game engine.

A estereoscopia é a área do conhecimento que aborda a visão em três dimensões, mas se limita, por definição, apenas às técnicas que possibilitam a reconstituição de uma cena tridimensional observada através de pelo menos dois pontos de vista distintos, que no caso dos seres humanos é a cena reconstituída no cérebro a partir das imagens obtidas pelos olhos. Inicialmente, o presente trabalho consolida os principais conceitos e técnicas desta área abrangente, para em seguida propor formas de análise, comparação e classificação de técnicas de estereoscopia através de conceitos teóricos e métricas qualitativas e quantitativas. Complementando esta proposta, com base na revisão da literatura e nos resultados experimentais, a pesquisa busca avaliar vantagens e desvantagens entre as técnicas estereoscópicas e na estereoscopia como um todo, para alimentar discussões, tendências e desafios encontrados na aplicação da estereoscopia a sistemas de Realidade Aumentada (RA), em particular sistemas de tele-presença com vídeo-avatar, e na área de jogos. / Stereoscopy is the area of knowledge that addresses three dimensional vision, but its restricted to, by definition, the techniques that allows the reconstruction of a three dimensional scene observed from two different points of view at least, in the case of human beings it is the scene reconstructed in the brain from the images obtained by the eyes. Initially, the present work consolidates the main concepts and techniques of this extended area, considering, after that, ways of analysis, comparison and classification of stereoscopy techniques through qualitative and quantitative metrics and theorical data. Additionally, based on literature review and in experimental results, the research try\'s to evaluate advantages and disadvantages between stereoscopy techniques and in stereoscopy as a whole, to stimulate discussion, trends and challenges found when merging stereoscopy to Augmented Reality (AR) systems, in particular tele-presence systems with video-avatar, and computer games.
