<p>This thesis is about the design and evaluation of a graphical display that aims at showing the behavior of a complex automated system in action. A problem with complex automation is that it sometimes surprises the user by performing actions that were not expected. The reason of this is poor communication of system activities. In order to study how to design for anticipative automation communication a prototype around automatic vehicle driving on highways was designed and evaluated. The design work focused on designing a display that contained anticipation as a use quality. This resulted in a display design that aimed at representing the working scene in such a way that the user would be able to recognize and compare the system view with the real situation. In order to accomplish this, three layers of information were merged together in the display, these layers were; the automaton’s image of how the world is seen, the way that image is perceived and interpreted in terms of system action necessity and out of that the actions that the system plans to perform in the near future. The evaluation of the design prototype showed that it was possible to anticipate system actions but that the information detail level was insufficient for the evaluators to completely trust system decisions. The evaluation also showed that trust can be created by letting the automaton represent the perception of the situation in such a way that the user is able to compare it to personal experience from performing the task manually. Anticipation can be created through showing what future the automaton is expecting and what actions that needs to be performed in order to reach or maintain the general system task or goal.</p>
