Viking Ship Project

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/AMFPerl
• 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 SocketScanSocket'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
