Presentation outline
Our working definition of usability
Case study #1: Abrumet web portal
Case study #2: Arthur multi-platform system
Conclusion

What is usability? (1/3)
Ergonomics in general
Goal: to design any system so that it can be used effectively and efficiently by a given population of users
Means: to rely on efficient work procedures respecting health and well-being of end users
Software ergonomics = Usability
Our working definition
Utility
Adequacy of user interface with respect to functional requirements of the system
Is independent of the end user
Usability
Adequacy of user interface with respect to operational needs of the end user
Is dependent of the end user

Utilité
assure un grand nombre de fonctions utiles pour l'utilisateur, pour un traitement de texte :
créer une table des matières
avoir un correcteur orthographique
déplacer des blocs d'un endroit à un autre
Utilisabilité :
facilité d'usage
accepte les erreurs de l'utilisateur
offre la possibilité de les corriger
ne bloque pas en cas d'erreur
facilité d'accès aux fonctions
commandes, messages, icônes compréhensibles
Certains logiciels sont riches en fonctions (utilité), mais difficiles à exploiter (utilisabilité)
Utilité :
les utilisateurs intensifs préfèrent parfois utiliser un outil riche, mais difficile à utiliser plutôt qu'un outil facile à utiliser, mais pauvre
Utilisabilité :
pour les utilisateurs novices ou épisodiques, la facilité d'emploi est un critère prioritaire
l'attitude de l'utilisateur vis-à-vis de l'outil dépend de son interface

Multi-platform for Emergency [Amouh et al.,2005]

Multi-platform for Emergency
Three platforms
Pocket PC
Desktop PC
Wall Screens

Multi-platform for Emergency
Model and method
Design the reference screen first
Refine the others screens later
By applying graceful degradation
By applying transformation techniques

Conclusion
Usability applyies everywhere
Most known form: web sites
Towards Accessibility of web sites
Towards Healthcare systems
