  1. Viking Ship Project INF5261 Kham Viravong - khamphiv Paulo Fierro - paulof

  2. Project Vision • To use mobile technology in ethnographic studies • To present relevant cultural-historical media on-demand

  3. What is ethnography? • Ethnography is a category of human-computer interaction research • Adapted from sociology and anthropology

  4. Project scope • FORNEM – an initiative in the documentation and digital archiving of qualitative, video-based research material • Our primary concern is the presentation of the third Viking boat from the Gokstad excavation

  5. Why use mobile technology? • Digital technologies allow the co-ordination of fieldwork documentation and analysis in new and interesting ways • Handheld devices make the researcher's communication with the research objects easier, by way of easier storing and simpler access to empirical material in digital form

  6. The Viking Ship Museum • Viking ship exhibition • Presenting the media as a narrative • Presenting the media where most relevant

  7. Which mobile technology? • The purpose of this project is to deliver ”high-quality” streaming video on-demand • Currently the only relevant device is a PDA

  8. Positioning: GPS • Accuracy of ~10m • Not applicable for in-door use • GPS drifting • Can be turned off at any moment

  9. Positioning: Wi-Fi • Ekahau Positioning Engine 3.0 • Access points determine client position • Accurate (up to 1m) • Proprietary solution • Integrate SDK • Expensive!

  10. Positioning: Bar code scanning • PDA scans barcode • Client requests media for particular barcode • Server returns relevant media based on predetermined ”grid system” • Quasi-positioning • Inconvenient due to extremely limited range

  11. Positioning: RFID • Same principle as barcode scanning • Cheapest solution ($0.80 - $40 per tag) • Very usable range (~3 – 100m) • Simultaneous reading (hundreds to thousands)

  12. Content delivery • PDA accesses WISE system via wLAN • PDA reads nearest tag ID and requests content from server • Server returns relevant media based on tag ID. ”Quasi-positioning” • User reads/streams media

  13. Flash Client application • Best technology available for streaming media • Available on all major PDA platforms (Windows Mobile, Symbian) • Easy, rapid development • Ability to create custom UI • Tiny footprint

  14. Technologies used • Macromedia Flash MX • ActionScript • Flash Remoting • AMF-PHP/AMF::Perl • mySQL • Vegas Video • AVID

  15. The two-tier model • Content delivery, development of client/server architecture • Integration of positioning system

  16. The prototype • Limited content • Input-based ”positioning”

  17. Future development • Integration with aforementioned positioning solution • Possible integration with existing AVID video database

  18. Future technologies • RFID – SocketScan”Socket's SocketScan software sends tag ID code to any Windows application as virtual keystrokes” • No need for custom written C/C++ client – Flash handles everything • ”Theoretically simple” implementation
