Towards for Analyzing Alternatives of Interaction Design Based on Verbal Decision Analysis of User Experience

Marília Soares Mendes, Ana Lisse Carvalho, Elizabeth Furtado, Plácido Rogério Pinheiro


In domains (as digital TV, smart home, and tangible interfaces) that represent a new paradigm of interactivity, the decision of the most appropriate interaction design solution is a challenge. HCI researchers have promoted in their works the validation of design alternative solutions with users before producing the final solution. User experience with technology is a subject that has also gained ground in these works in order to analyze the appropriate solution(s). Following this concept, a study was accomplished under the objective of finding a better interaction solution for an application of mobile TV. Three executable applications of mobile TV prototypes were built. A Verbal Decision Analysis model was applied on the investigations for the favorite characteristics in each prototype based on the userâ??s experience and their intentions of use. This model led a performance of a qualitative analysis which objectified the design of a new prototype.
