Immersive Configuration

In user interfaces in ubiquitous augmented reality, information can be distributed over a variety of different, but complementary, displays. For example, these can include stationary, opaque displays and see-through, head-worn displays. Users can also interact through a wide range of interaction devices. In the unplanned, everyday interactions that we would like to support, we would not know in advance the exact displays and devices to be used, or even the users who would be involved. All of these might even change during the course of interaction. Therefore, a flexible infrastructure for user interfaces in ubiquitous augmented reality should automatically accommodate a changing set of input devices and the interaction techniques with which they are used. This project embodies the first steps toward building a mixed-reality system that allows users to configure a user interface in ubiquitous augmented reality.
This project has been conducted at Columbia University by a a visiting scientist from our research group. .

Demo Immersive (Movie)

SHEEP

In this demo, we use a multiplayer shepherding game to explore the possibilities of mutimodal, multiuser interaction with wearable computing in an intelligent environment. The game is centered around a table with a beamerprojected pastoral landscape. Players can use different intuitive interaction technologies (beamer, screen, HMD, touchscreen, speech, gestures) offered by the mobile and stationary computers. Building on our DWARF framework, the system uses peer-to-peer, dynamically cooperating services to integrate different mobile devices (including spectators laptops) into the game.

CAR

The goal of CAR is to create a collaboration platform for computer scientists (UI programmers) and non-technicans (human factors, psychologists etc.). The platform allows collaborative design of visualizations and interaction metaphors to be used in the next-generation cars with Head-Up Displays. We focus on two scenarios: parking assistance and a tourist guide.

TRAMP

The TRAMP system (Traveling Repair and Maintenance Platform) was developed in a Praktikum with 50 student participants. The realized scenario was to guide a mechanic who is equipped with a wearable computer to a customer who has a car breakdown. The mechanic is also instructed by the system on the actual repair process to fix the car. (The project has been conducted at the Chair for Applied Softwareengineering.)

Pathfinder

This was the first demonstration system for the DWARF framework. It shows Yet-Another-Campus-Navigaiton scenario but stays here for sentimental historic reasons (since it shows the old location of the computer science department in the heart of munich).

ARCHIE

For producing buildings in a collaborative way with all involved persons, ARCHIE (Augmented Reality Collaborative Home Improvement) shall be responsible for giving the system user the most familiar way to handle the information during the development process.
