abstract: This thesis describes research into the application of socially reflective, or "Slow", design principles to modern mediated systems, or "Fast" technology. The "information overload" caused by drastic changes in the nature of human communications in the last decade has become a serious problem, with many human-technology interactions creating mental confusion, personal discomfort and a sense of disconnection. Slow design principles aim to help create interactions that avoid these problems by increasing interaction richness, encouraging engagement with local communities, and promoting personal and communal reflection. Three major functional mediated systems were constructed to examine the application of Slow principles on multiple scales: KiteViz, Taskville and Your ____ Here. Each system was designed based on a survey of current research within the field and previous research results. KiteViz is a visually metaphorical display of Twitter activity within a small group, Taskville is a workplace game designed to support collaboration and group awareness in an enterprise, and Your ____ Here is a physical-digital projection system that augments built architecture with user-submitted content to promote discussion and reflection. Each system was tested with multiple users and user groups, the systems were evaluated for their effectiveness in supporting each of the tenets of Slow design, and the results were collected into a set of key findings. Each system was considered generally effective, with specific strengths varying. The thesis concludes with a framework of five major principles to be used in the design of modern, highly-mediated systems that still apply Slow design principles: design for fundamental understanding, handle complexity gracefully, Slow is a process of evolution and revelation, leverage groups and personal connections to encode value, and allow for participation across a widely distributed range of scales. / Dissertation/Thesis / M.S.D.

Parte do pressuposto que decisões podem ser estudadas por meio do sistema experiencial, que é rápido, geralmente automático e não acessado através da consciência. Compreende também a influência de elementos subjetivos em processos decisórios. Nessa perspectiva, o objetivo aqui é o de analisar como elementos do sistema experiencial influem no estabelecimento da confiança necessária à assunção de riscos em processos decisórios de mudanças organizacionais estratégicas. Quatro organizações brasileiras que passaram por mudanças estratégicas são estudadas, a partir de uma abordagem qualitativa. Os dados sobre os casos foram obtidos por meio de entrevistas em profundidade semi-estruturadas, realizadas com os executivos que faziam parte das organizações, e essas entrevistas foram analisadas em seu conteúdo. Os resultados apontam para a influência de elementos do sistema experiencial em processos decisórios de mudanças organizacionais estratégi / This study discusses relations between decision making, risk and trust. Decisions can be studied by experiential system, which is quick, generally automatic, not conscientiously perceived, and involves subjective elements in decision processes. This research is streamed aside the experiential view analysis, aiming to analyze how experiential system elements interfere in necessary trust setting, that allows risk taking in strategic changes decision processes. Four brazilian organizations that passed through strategic changes are studied, based on a qualitative perspective. Data were collected from semi-structured questionnaires, applied to senior executives in in-depth interviews. Interviews contents were analyzed, and the outcomes pointed out the influence of experiential system elements in strategic changes decision processes. It emerges that those elements do not impact in reality, changing risk or uncertainty conditions of the situations that executives are passing through, but they interfere in executives
