The effectiveness of ergonomic criteria for the evaluation of user interfaces was assessed. Two groups of experts evaluated the interface of a musical database application. After an exploration-diagnosis phase, the participants evaluated the same interface states with or without ergonomic criteria. Preliminary results show that in the first phase, the(More)

OBJECTIVE The aim of this work is to assess how adding a driving-related task affects the detection of objects in peripheral vision, under mesopic conditions. BACKGROUND The main index used to assess the quality of road lighting installations refers to simple detection tasks in foveal vision, which raises methodological and practical questions. METHOD(More)
The aim of this paper is to present guidelines for conducting a type of user requirements analysis based on a constructivist approach. This method consists of meetings of experts of a targeted user community called: the Expert Community Staff. First, we present the theories involved in this approach that is both based on social construction of technology(More)
The Small Target Visibility (STV) model is the main model used to assess the quality of road lighting installations (IESNA, 2000). However, this model is based on a simple detection task in foveal vision using psychophysical data from laboratory conditions. The purpose of this study was to evaluate the impact of a complex background and apparent motion on(More)
The relative effectiveness of the Ergonomic Criteria and the ISO/DIS 9241-Part 10 Dialogue Principles in guiding the evaluation of user interfaces was assessed. Afler a demonstration of a musical database application and a fme exploration phase, three groups of participants (Criteria ISO, Contxol) were invited to evaluate the interface of the application.(More)
This article presents the advantages and drawbacks of individual and paired-user testing in terms of number and type of usability problems uncovered. Thirty-two participants had to perform 8 tasks designed to allow the evaluation of interactive tv services. For half of the participants (16) the test session was conducted individually: for the other half,(More)
