Towards Action-Oriented User Interface Design

The ultimate goal of user interface design is to develop a product which people can use to reach their goals. By action we normally refer to our attempts to reach certain goals, and this is why it is natural to think user interface design as an activity we engage in when designing tools, instruments or technologies for people to realize their action goals. This paper suggests a novel action-oriented user interface development method that aims to develop a user interface interaction model. This interaction model is based on an organized tree structure composed of node states with relevant usability-related attributes and operations between the nodes.
