Esta dissertação apresenta um estudo comparativo pormenorizado de três plataformas cloud gaming proeminentes: GeForce Now, PlayStation Plus e Xbox Cloud Gaming. A principal questão de investigação que orienta esta investigação é: qual das plataformas de cloud gaming responde melhor às necessidades do utilizador comum? O estudo utiliza uma metodologia multifacetada que combina abordagens qualitativas, quantitativas e comparativas.
Para os testes de usabilidade, os avaliadores interagiram com cada plataforma seguindo um guião de utilizador estruturado, executando tarefas predefinidas em dispositivos específicos. Um programa registou o tempo necessário para cada tarefa, permitindo uma análise precisa. Os valores de tempo foram depois agrupados numa folha de Excel, permitindo o cálculo dos tempos médios das tarefas para cada plataforma em cada dispositivo. A análise posterior incluiu a determinação do tempo médio para cada tarefa em todos os testes e a avaliação de qualquer evolução do tempo, indicativa do efeito de aprendizagem, da primeira para a segunda ronda.
O questionário envolveu a resposta dos avaliadores a dez perguntas sobre a usabilidade e o desempenho gerais, abrangendo fatores como a facilidade de utilização, a clareza gráfica, a velocidade de execução e a capacidade de resposta às interações. As respostas foram registadas numa escala de cinco pontos (discordo totalmente a concordo totalmente). Os dados do questionário foram processados para análise, contribuindo para a avaliação da experiência global do utilizador de cada plataforma.
Os resultados, baseados nos cinco fatores e nos testes de usabilidade, permitiram-nos compreender quais as plataformas de cloud gaming que melhor satisfazem as necessidades dos utilizadores comuns. Apesar das descobertas notáveis, alguns testes, como conetividade/latência e tempos de resposta de input, não puderam ser realizados devido a limitações. Além disso, a disponibilidade da PlayStation Plus estava limitada a dispositivos específicos, o que afetou a abrangência do estudo.
A importância deste estudo reside no seu enfoque único nas interações dos utilizadores com as plataformas de cloud gaming, o que o distingue da investigação existente que avalia predominantemente características específicas das plataformas. Ao empregar métodos científicos, esta investigação contribui com uma abordagem valiosa para os utilizadores comuns escolherem uma plataforma de cloud gaming adequada às suas preferências e necessidades.
This dissertation presents a comprehensive comparative study of three prominent cloud gaming platforms: GeForce Now, PlayStation Plus, and Xbox Cloud Gaming. The primary research question guiding this investigation is: which of the cloud gaming platforms better responds to the necessities of the normal user? The study employs a multi-faceted methodology combining qualitative, quantitative, and comparative approaches. For the usability tests, evaluators interacted with each platform following a structured user guide, executing predefined tasks on specific devices. A program recorded the time taken for each task, allowing for precise analysis. The time values were then collated in an Excel sheet, enabling the calculation of average task times for each platform on each device. Further analysis included determining the average time for each task across all tests and assessing any evolution of time, indicative of the learning effect, from the first to the second round. The questionnaire aspect involved evaluators responding to ten questions gauging general usability and performance, encompassing factors such as ease of use, graphical clarity, speed of execution, and responsiveness to interactions. Responses were recorded on a five-point scale (totally disagree to totally agree). The questionnaire data were processed for analysis, contributing to the evaluation of each platform's overall user experience. The results, based on the five factors and usability tests, allowed us to understand which cloud gaming platforms best meets the needs of the regulars user. Despite notable findings, certain tests, such as connectivity/latency and input response times, could not be conducted due to limitations. Additionally, the availability of PlayStation Plus was restricted to specific devices, impacting the comprehensiveness of the study. This study's significance lies in its unique focus on user interactions with cloud gaming platforms, setting it apart from existing research that predominantly evaluates platform-specific features. By employing scientific methods, this research contributes a valuable approach for normal users to choose a cloud gaming platform tailored to their preferences and needs.
