New Directions in Human-Computer Interaction: Blended Interaction


Harald Reiterer









Do/Thu: 15:15-16:45


The course "New Directions in Human-Computer Interaction: Blended Interaction´╗┐" gives a deep insight into the theories, conceptual foundations, design approaches, and practical implementation of "Blended Interaction." This new form of interacting with interactive system is very different from traditional WIMP (=Windows Icons Menus Pointer) approaches such as today's mouse-operated graphical user interfaces or web pages.

Instead, new post-WIMP interaction modalities are employed (e.g., multi-touch, tangible user interfaces, digital pens, gestures, speech) to "blend" the world of virtual objects and ubiquitous computing power with our familiar physical and social work environment that goes far beyond our desktops. See literature below for an introduction into "Blended Interaction" (both English and German are available).

The course will consist of a theoretical part that run throughout the semester. The following topics will be addessed:

  • Which theories and conceptual frameworks from cognitive science, psychology, and the social sciences can help us to understand and predict the effects of Blended Interaction on the users?
  • What means intuitive interaction?
  • How can we use the theory of proxemics and the proxemity dimensions for implicit interaction?
  • How to combine stationary displays, physical objects, and mobile devices to create blended work environments?
  • How to use large interactive tabletops, large displays, or multiple mobile displays to foster efficient collaboration between multiple users?
  • How to combine new modalities (e.g., body or touch gestures, pen or speech input) to afford "natural" interaction? And what does "natural" or "intuitive" interaction actually mean?
  • How to use Virtual Reality and Augmented Reality techniques to support Blended Interaction? What are Interactive Mixed Realtiy Spaces?
  • What kind of programming models and languages are useful to support concurrent user activities at multiple points of actions (e.g., simultaneous input from multiple fingers, devices, gestures, physical objects, voices, or computer vision)?
To participate in the course, previous participation in the BA-course "Interactive Systems" (University of Konstanz) or equivalent lectures like Human-Computer Interaction, Usablity Engineering from other lectures or universities is recommended.
