Shared Space - Benutzungsschnittstelle im Cyberspace

In der CC-Nacht präsentiert das Heinz Nixdorf Institut (HNI) Paderborn zusammen mit dem Forschungsinstitut Human Interface Technology Lab (hitlab) der Universität Washington den Einsatz und die Entwicklung von innovativen Mensch-Maschine-Schnittstellen. Diese beruhen auf der Technologie Augmented Reality, in der Anwender mit einer Datenbrille die reale Umgebung sehen, die aber zusätzlich um computergenerierte Bilder ergänzt wird.

In der CC-Nacht werden zwei AR-Projekte präsentiert:
  • Ein Memory-Spiel im Cyberspace, an dem 1 bis 4 Mitspieler teilnehmen können.
  • Ein Lexikon, das mit Hilfe von 3D-Objekten, Animationen und Audiounterstützung neue Möglichkeiten des interaktiven Lernens gestattet.

Beteiligte Organisationen:

Human Interface Technology-Lab (www.hitl.washington.edu)
HNI Paderborn (wwwhni.uni-paderborn.de)

Shared Space merges real and virtual worlds in a way that can radically enhance face to face and remote collaboration. By wearing a lightweight see-through head mounted display, the visitor is able to see three-dimensional virtual images overlaid on the real world and attached to real world objects. For face-to-face collaboration, this allows users to see each other at the same time as the virtual images between them, supporting natural communication between users and intuitive manipulation of the virtual objects. For remote collaboration, Shared Space allows life-sized live virtual video images of remote collaborators to be overlaid on the local real environment, supporting spatial cues and removing the need to be physically present at a desktop machine to conference. In both cases, computer vision techniques are used to precisely register virtual images with physical objects, extending the "Tangible Interface" metaphor. The Shared Space approach is presented in the context of a collaborative application that allows face-to-face and remote users to create interactive art together using virtual animated characters and props in a real tabletop environment.
