e-SAM: uma proposta de solução para apoiar a avaliação do estado afetivo de usuários na interação com sistemas computacionais

Abstract

When a person uses an interactive computing system, s/he has a well-defined goal, such as communicating with other people, making a purchase, studying certain content, etc. To achieve this goal, s/he plans actions, exchanges stimuli and responses with the system and, finally, checks if his objective has been achieved. This interaction takes place through the system interface. During an interaction, the feelings and emotions experienced by the user cannot be predicted or controlled and can be influenced by several factors such as problems with the interface. The Human-Computer Interaction area is interested in building interactive systems with high quality of use. One of the activities proposed to achieve this quality is the evaluation activity, which aims to identify problems in the interface and in the interaction of computer systems. Among the various existing assessments, there is the Self Assessment Manikin (SAM) instrument, an artifact that aims to assess a person’s affective response to an event or stimulus. In this work, a solution, called e-SAM Electronic Self Assessment Manikin, was presented to support the evaluation of the affective response of users to the interaction with computer systems with the support of the SAM instrument.
