Ten Emotion Heuristics: Guidelines for assessing the user’s affective dimension easily and cost-effectively

Abstract

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.

Analysis of Permanence Time in Emotional States: A Case Study Using Educational Software

“…Then, they discussed together the annotations and reached an agreement. The coding of the facial expressions was performed according to guidelines suggested by (Lera and Garreta-Domingo, 2007), in which they propose 10 heuristics of human behavior in order to infer what emotions humans are experiencing at a given moment.…”

Evaluating interactive systems from an emotional perspective

“…-A set of guidelines has been developed by Lera and Garreta-Domingo (Lera & Garreta-domingo, 2007) for evaluating efficiently and at a low cost the affective states of users by considering their reactions during the process of evaluating interfaces. This is intended to complement analysis based on objective, quantitative data obtained from usability testing and on subjective responses obtained from post-test questionnaires.…”

“…In recent years, an important number of projects (Agarwal & Meyer, 2009;Lera & Garreta-domingo, 2007;Branco, Firth, Encarnação & Bonato, 2005;Petrie, 2010)we explored the use of two techniques: an emotional think aloud protocol and an emotion word prompt list (EWPL have aimed to address the emotional aspects in the evaluation of usability of interactive systems (and to enhance user experience). Objective and subjective aspects of emotions are addressed by various methods used to evaluate interactive systems (Bak, Nguyen, Risgaard & Stage, 2008) Still, existing methods have significant limitations.…”

Affective negotiation support systems

“…This also makes computing with them, e.g., for affective preferences, more difficult. Other approaches are able to, in principle, extract detailed affective information in a non-invasive manner but involve the use of human observers to evaluate the feedback and are more focused on measuring human emotion during the process of product development [41,90]. Such approaches give detailed affective feedback but are not suitable for online affect measurement: i.e., affect measurement aimed at getting real-time affective feedback in a format that is usable by a computer system.…”
