MotivationIntroduction

I Software systems are abstractI Most customers see the GUI as the software system

I Vision: Haptic, physical 3D models of software systems

Possible ScenariosIntroduction

1. Customer dialog(“Change in back-end from x to y costs 10,000C”)

2. Communication basis for software developers/architects

Physical 3D Model AdvantagesIntroduction

I Occlusion “resolved” in a natural wayI “Something to touch”I No extra equipment/monitors/glasses
