Towards a new method for the evaluation of reality based interaction

In this paper we present work toward a new method of evaluation for Reality-Based Interaction Styles that we call Cognitive Description and Evaluation of Interaction (CoDeIn). This framework is similar to GOMS, but also shares similarities with cognitive architectures, such as ACT-R and Soar. We apply this new approach to a Tangible User Interface, built as a Wizard of Oz interface, to illustrate the new method, and compare CoDeIn's results to a GOMS model. We show that CoDeIn provides some promise of representing the parallel processing and new modes of physical interaction inherent in reality-based interfaces, and CoDeIn does a better job in predicting the completion time of an example task than GOMS.
