PADRÕES DE DESIGN DE INTERAÇÃO PARA APLICATIVOS DE COMÉRCIO TELEVISIVO COM FOCO NA EXPERIÊNCIA DO USUÁRIO

Abstract

The aim of this dissertation is to develop a design pattern language for television commerce that can support designers and developers to create applications with positive user experiences. The research is divided into three phases. In the first phase, it was performed an analysis in twelve existing t-commerce applications in order to identify the purchase process and the elements of graphical user interface used to do online shopping. In the next phase, three focus group sessions composed by 26 participants was performed in order to collect ideas and expectations resulted from anticipated use of application t-commerce for formulating hypotheses to be tested in the next phase. In the third phase, an experiment with 8 volunteers have been performed and it is consisted to show videos demonstrations with various solutions found in the previous phases and then gather their opinions to characterize each solution found. Also, at that phase, it was possible to define users profiles which will assist designers and developers alongside the design pattern language. The results obtained in these three phases were organized into a framework for design patterns that formats the results in a context, problem and solution. The pattern design framework allows helping designers and developers in the design of t-commerce application with improved user experiences.
