Beschreibung:

Ein Sprichwort sagt, 1 + 1 sei mehr als 2. Gemeint ist damit, dass Zusammenarbeit effektiver sein kann als parallele Einzelarbeit. Doch wie lässt sich diese Behauptung überprüfen? Bei welcher Art von Aufgaben können wir von Gruppenarbeit profitieren? Welche Faktoren beeinflussen die Qualität gemeinsamer Aktivitäten und den Erfolg einer Kooperation?

Im Rahmen des Projektes wollen wir bestehende Schnittstellenkonzepte für Gruppeninteraktion in virtueller Realität bewerten, verbessern und die besten Möglichkeiten miteinander kombinieren. Die Nutzbarkeit und Nützlichkeit des resultierenden Gesamtsystems für Gruppenarbeit soll am Ende in einer formalen Studie verifiziert werden.

Die nötigen Programmierkenntnisse zur Implementierung von Testanwendungen in Python und C++ mit Avango-Guacamole werden vorausgesetzt.

Inhalte:

  • Literaturstudium
  • Computergestützte Zusammenarbeit
  • Entwurf und Evaluierung von Benutzerschnittstellen

English:

Something can be more than the sum of its parts, i.e. active collaboration can be more effective than individual work in parallel. However, can we validate this assumption? Which tasks benefit most from group work? What affects the quality of joint activities and the success of cooperation?

In the project, we aim to evaluate and improve existing interfaces for group interaction in virtual environments. We will combine the best of them into a holistic groupware system and evaluate its usability in a formal study.

Students should have the necessary programming skills for writing test applications in Python and C++ for the Avango-Guacamole framework.

Topics:

  •  Literature studies
  • Computer-supported collaborative work
  • Design and evaluation of user interfaces
