Abstract

Television commerce represents a significant opportunity for worldwide market due to the digital TV transition in several countries. In order to provide a design guidance for these applications, we developed a T-commerce Posture HCI Design Pattern based on user experience research. Three focus groups are composed of twenty-five participants and an experiment with eight volunteers were performed. The results are described as a design pattern template composed of four types of t-commerce applications. Each type presents a recurrent problem, a proven solution and a context. The developed design pattern helps designers to decide the t-commerce main interactions focusing on better user experience.
