Everyone

knows

An first AR Webbrowser approach

Lessons learned from many Projects…

� Complex 3D visualization (3D-css is nice but…)

� Server-Based Approach and Device-Based

� Vision-Supported/Based Tracking

Tracking and events:

� 2D-Projected Positions

� Detection Events (out of image, coarse

recognition,exact…)

� Dynamic Content

� Dynamic Tracking (Load Server Generated Trackers)

� Packagable Content for offline use

� Debuggable
