Modelling Long Term Goals

摘要

Goals have long been recognised as important in user modeling and personalisation. Surprisingly, little research has dealt with user model representations for people's long term goals. This paper describes our theoretically-grounded design of user models for long term goals; notably, the theory points to the critical role of the user interface to this Goal Model, to enable people to set, monitor and refine their models over the long term. We report on a multi-study evaluation of the tightly coupled user model representation and Goal Interface, based on a preliminary lab study (16 participants), and a field trial (14 participants), starting with the lab study and then the in-the-wild use and the questionnaires. This provides multiple sources of evidence to validate the usefulness of our Goal Model to represent three long term health-related goals. It shows that the Goal Interface is usable and aids people in setting their long term goals.
