    • Codein-A New Notation for GOMS to Handle Evaluations of Reality-Based Interaction Style Interfaces 

      Christou, Georgios; Ritter, Frank E.; Jacob, Robert J.K. (2012-03-01)
      We propose a new diagrammatic notation system for Goals, Operators, Methods, Selection rules (GOMS), called Codein, with extensions to support the evaluation of Reality Based Interaction Styles. The proposed notation gives ...
    • Evaluating and comparing interaction styles 

      Christou, Georgios; Jacob, Robert J.K. (2003-12-01)
      Research has created many new generation (post-WIMP) Interaction styles (IS) in the past years. From Ubiquitous to Affective Computing, researchers have not kept a uniform standard, so that Interaction Styles (IS) could ...
    • Modeling prehensile actions for the evaluation of tangible user interfaces 

      Christou, Georgios; Ritter, Frank E.; Jacob, Robert J.K. (2008-09-23)
      Prehension, or reaching-to-grasp is a very common movement performed by users of Tangible User Interfaces (TUIs) because through this movement users can manipulate tangible artifacts. Here we present an experiment that ...
    • Modeling the task: Leveraging knowledge-in-the-head at design time 

      Christou, Georgios; Jacob, Robert J.K.; Cheng, Pericles (2006-12-01)
      A key problem in Human Computer Interaction is the evaluation and comparison of tasks that are designed in different interaction styles. A closely related problem is how to create a model of the task that allows this ...
