IPAR Projekt-LogoEine Benutzerin ändert mittels einer Mobile-Augmented-Reality-Anwendung die Farbe von Gardinen auf einem Tablet.

Die Erweiterte Realität (Augmented Reality) hat dank mobiler Endgeräte das Potenzial, künftig auch jenseits industrieller Anwendungen verstärkt zum Einsatz zu kommen. Zum Beispiel können im Bereich Architektur und Innenarchitektur virtuelle Möbel oder Fenster in realen Räumen platziert werden.

Für die Manipulation einer möglichst überzeugend augmentierten, realen Welt werden sowohl in Echtzeit generierte, photorealistische Darstellungen als auch natürliche, nahtlose Interaktionsformen mit den virtuellen Objekten benötigt. Dies sind zwei wesentliche Erfolgsaspekte für Augmented Reality-Anwendungen, die im Projekt IPAR erforscht werden.

Grundlage ist zunächst die Vermessung der komplexen, realen Lichtverhältnisse, die als Eingabe für die Echtzeit-Beleuchtung der virtuellen Objekte verwendet werden. Neben der Veränderung der real wirkenden virtuellen Objekte wird damit auch eine virtuelle Manipulation realer Objekte bei konsistenter Beleuchtung möglich. Für die Interaktionen werden einerseits indirekte Techniken untersucht, bei denen in der Hand gehaltene moderne Tablets als sogenannte „Magische Linsen“ zum Einsatz kommen. Analog zu einem Kameradisplay stellen sie ein Fenster in die virtuell angereicherte Realität dar, durch das Anwender Gegenstände manipulieren können. Andererseits sollen auch direkte gestische Interaktionstechniken in Kombination mit einer mobilen Projektion auf reale Objekte entwickelt und evaluiert werden.

Neben Forschungsfragen zur Vermessung und Modellierung zeitlich und räumlich variierender Beleuchtung in Innenräumen wird im Forschungsprojekt untersucht, welche Herausforderungen sich aus der nahtlosen Integration bezüglich der Nutzerinteraktion und Akzeptanz ergeben.
