Emotional appeal is a key dimension in user experience that often goes unmeasured in most user-centered design projects. This paper presents preliminary work for developing a set of guidelines for efficiently, easily and cost-effectively assessing the users' affective state by evaluating their expressive reactions during an interface evaluation process. The evaluation of this dimension complements the analysis of the objective and quantitative data gathered through usability tests and the subjective feedback provided through post-test questionnaires.

This paper presents a proposal for the introduction of the affective dimension in online learning applications. The paper focuses especially on affective data assessment by presenting a study of 'emotional inference' through the triangulation of three techniques: facial expression interpretations, pupil size and students as self-evaluators. In order to validate the combination of these techniques as a specific methodology, we planned a test with seven students interacting with a virtual learning environment. At the present time we are ready to present the first results and the correlations between the used techniques. The study is aimed to contribute to the development of truly affective computerbased learning applications. More specifically, we believe it can contribute to telemedicine as it promotes a methodology for subject emotional data analysis, being computer-based affective analysis a young field that needs new developments.

Abstract. The emotional dimension of users of information and communications technologies (ICT) is a key aspect in user experience (UX), as designers' main objective is to ensure users are happy (satisfied, engaged) with their interaction designs. However, current UX design methods focus on ensuring that efficacy (success achieving a specific task) and efficiency (in the fastest, best way possible) are successfully achieved. The satisfaction of the user is evaluated at the end of the process, and evaluated in reference to the efficacy and efficiency of their experience. In this paper, the author presents a new approach (EmotionCentered-Design, or ECD) in which the key to successful interaction design (happy users) is brought about by placing emotions at the center of the design process, versus doing so at the end. By doing so, designers can deliver more significant experiences, increase user experience satisfaction, and identify new ways to innovate in interaction design, as well as add more value to users.
