Abstract: Since mobile TV represents a new paradigm for interaction design, many different candidate solutions of interaction can be possible. Following this concept, a study was accomplished with the objective of finding a better interaction solution for an application of mobile digital TV. Three executable prototypes of an application of mobile TV were built. A multicriteria model of verbal decision analysis was applied to those three alternatives by aiming at investigating the favourite characteristics of each prototype based on user|s experience and their intentions of use. This model resulted in a method that supports designers in the qualitative analysis of alternatives and collaborative conception of the best solution of interaction to innovative products.
