Solving one task with many devices
Marta Kristin Larusdottir · 2002
The complex world in which a user can accomplish the same task with many different devices puts many demands on user interface models. This presentation describes such a project where a user-centered approach was used. Models were used to describe users, tasks, user environments and the user interface for different mobile and desk devices. Since tasks require users to go between devices, a navigational model and a more abstract architectural model were developed. Additionally the preparation of usability tests with many devices and environments are described.
