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

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

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

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

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

The Viking Ship Museum  Viking ship exhibition  Presenting the media as a narrative  Presenting the media where most relevant

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

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

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

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

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

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

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

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

The two-tier model 1. Content delivery, development of client/server architecture 2. Integration of positioning system

The prototype  Limited content  Input-based ”positioning”

Future development  Integration with aforementioned positioning solution  Possible integration with existing AVID video database

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
