A Task Oriented Approach to Delivery in Mobile Environments

The delivery of Internet content on mobile devices not only poses technological challenges, but also raises usability issues. In this paper, we propose an approach driven by tasks, where a task model is used to dynamically drive the interaction with the user and adapt the content to the device. We argue that such an approach is appropriate given the use of mobile devices for very specific tasks. We present an application to the journalistic domain: we have built a knowledge portal to assist a reporter writing an article. This portal demonstrates how a task model can be used for content adaptation on a mobile device.
