Temporal Aspectsof Usability Including Time in the Netion of Interactor M.Mezzanolle & F.Paterno' Introduction The advent of user interfaces using several media in order to provide users with information and to interact with them has raised the necessity of a clear understanding of the role of time in user interactions. In fact, information needs to be composed and distributed among media which have different times for performing processing and presentation of information. Generally, being able to describe temporal parameters is essential in order to have a real description of temporal dependent systems, where particular states can be reached if some temporal actions have been executed. It is thus important to have structures and systematic approaches to specify Interactive Systems so that time-related aspects can be addressed as well. Having these types of methods is an important pre-condition to be able to address usability issues related with time. The concept of an interactor is an abstraction which captures specific requirements of software objects which interact with users. The software architecture of an Interactive System can be built by composing instances of the interactor model which communicate with each other. The model allows designers and developers to identify easily the
