Emotion and Interface Design
Authors: Damien Lockner, Nathalie Bonnardel
Abstract: Traditionally, human-computer interaction is conceived and assessed through the restrictive scope of usability. Although this approach has led to an overall improvement of the interfaces ease-of-use, it should now be overstepped. The question of the positive affect of users has become crucial for the interface project stakeholders. Our research is mostly turned towards applied perspectives. Our general hypothesis is that design strategies may affect positively the user, and influence a better attractiveness of the interface. Our objective is to define good design practices by assessing a set of emotional design patterns. In a first section, we will report an interview session with designers in order to identify any pattern of design for an emotional interface. Then, we will present and discuss a method to measure user’s emotion during an interface interaction experience. The experimental setup gathers screen records, face recognition, galvanic skin response, and questionnaires. These complementary sources bring forward the behavioral, physiological, and subjective emotional responses of the user. We will discuss how these resources can be used in order to measure the emotional effect of a specific user interface.
