Beschreibung:

Im Rahmen des Projektes untersuchen wir technische Möglichkeiten zur Strukturierung von kooperativer Interaktion mehrerer Benutzer in virtuellen Umgebungen. Insbesondere verfolgend wir dabei die Ansätze:

  • der Rollenverteilung durch dedizierte Werkezeuge,
  • der dynamischen Festlegung von Rahmenbedingungen für individuellen Eingaben sowie
  • des physikalisch simulierten Kräftegleichgewichte zwischen den Eingaben mehrerer Nutzer.      

Parallel zur konzeptionellen Entwicklung und prototypischen Implementierung verschiedener Entwürfe untersuchen wir Varianten des Softwaredesigns zum Umgang mit mehreren konkurrierenden Eingaben.

Lehrinhalte: 

  • Computergestütze Zusammenarbeit
  • Entwurf und Evaluierung von Benutzerschnittstellen
  • Softwareentwurf
  • Physiksimulation
  • Scenegraphen und Scripting

 

English:

Cooperative User Interfaces

In the Project we will explore the technological design space for structuring cooperative interaction of multiple users in virtual environments. In particular we will consider the following three approaches:

  • Dedicated user roles and dedicated input devices,
  • Dynamically controlled constraints to the input of individual users (guidance), and
  • A physics simulation for force-based input negotiation.

In parallel to the conceptual design and the prototypical implementation of the collaborative interaction techniques, we will analyze alternative software designs to better cope with multiple concurrent inputs.

Topics:

  • Computer-supported collaborative work
  • Scenegraph programming and scripting
  • Design and evaluation of user interfaces
  • Software design
  • Physics simulation
