Interaction Templates for Constructing User Interfaces from Task Models
Task modelling is well suited to identifying user goals and identifying the activities a user performs to achieve these goals. Some task model tools provide simulation capabilities and/or aid in the construction of concrete user interfaces. When it is desirable for the simulated or constructed interface to be realistic, the task model must be specified in considerable detail. Unfortunately this is usually quite onerous for medium to large size systems, for context-dependent user interfaces, and for highly interactive user interfaces. This paper introduces ‘Interaction Templates’: pre-defined components that can be plugged into a task model to provide concrete dialogue and presentation. Interaction Templates define complex, context sensitive interaction that is to be incorporated into the target user interface and can be used when simulating a task model. Interaction Templates are bound to the task model using an explicit data model. We demonstrate the applicability of Interaction Templates with a case study.
