3DVN is a Mixed Reality platform for navigation assistance in indoor environments. It is built on top of a PC-based wearable computer running the Windows operating system and provides a multimodal user interface to navigate existing physical buildings. Specific features include wireless networking, data glove gestural input, voice communication, head-mounted display, and a 3DOF head tracker. Local positioning is performed using a software-only WLAN-based engine to accurately pinpoint the mobile device in three dimensions. We base this system on a simple theoretical framework for classifying interaction for mobile navigation assistance. Informal qualitative evaluation of our system seems to conform to predictions derived from our framework and shows the need for a rich set of interaction components for successful mobile navigation.

This project was conducted during a year-long project by third-year Computer Science & Engineering students at Chalmers with Niklas Elmqvist as their advisor.
