Design and Implementation of Mobile AR Device for Outdoor Augmented Reality in ARCHEOGUIDE Project

The ARCHEOGUIDE project innovatively offers cultural-heritage visitors archaeological information through augmented reality. Using see-through display and differential GPS, the system enhances user experience. Experimentation with HMD and Cam System led to optimizing computing power for performance. Future focus is on improving input devices for interaction ease.

  1. Design and Implementation of a Mobile Device forOutdoor Augmented Reality in theARCHEOGUIDE Project Tim Gleue, Patrick Dähne VAST(Visual Analytics Science and Technology) 2001

  2. OUTLINE • Introduction • System Diagram • System Introduction • EXPERIMENT • CONCLUSION

  3. Introduction • The ARCHEOGUIDE (Augmented Reality-based Cultural HEritageOn-site GUIDE) project aims at providing visitors of cultural-heritage sites with archaeological information in an innovative and compelling new way

  4. System diagram

  5. System introduction

  6. (Cont.) • Use a see-through scheme with the overlay images displayed “between” the real scene and the user’s eye • Displaying a readily mixed image comprised of the backgroundandthe virtual objects

  7. (CONT.) Primary requirements for a suitable camera: • Image quality • Maximum frame-rate(幀)

  8. (cONT.) • Field Of View (FOV) FOV=45

  9. (cont.) • Improve the accuracy of the position values, we use differential GPS(DGPS)

  10. (cONT.)

  11. (Cont.) • Although the user can see the interface at any time directly inside his field of view wearing the display on his head, he is not able to type text on-screen-menus of television sets, game consoles

  12. EXPERIMENT HMD(head-mount-display) & Cam System with Antenna & GPS console

  13. 6130+1160+670=7.9(kg)

  14. Experiment

  15. Conclusion • We decided to optimize for computing power instead of weight, mobility and robustness, since performance is crucial for an interactive system like ARCHEOGUIDE • To overcome the stated interaction difficulties and ergonomic weaknesses we work on an improved input device
