PersonnalOverlay

Principle

More systems, from ShiftSpace on the web to Layar on mobile phone, make Augmented Reality usable now. How can it be done efficiently?

Yasako from Denno Coil

Requirements

• Cross-systems
  • if you are using this system X on your mobile phone, Y on your laptop and Z on your TV, you should not need to re-write the same information again
  • if system X closes, you should not loose your information
• Personnalized
  • you should not be limited to only sold content

Potential solution

• regex-like datastructure
  • (pattern;information)
    • pattern
      • URL for online information
      • GIS for offline information (existing format?)
      • note that the 2 types of pattern are not excluse, i.e. an overlay can be both online and offline
        • example : a museum website (online) and the museum building (offline)
  • information
    • additional information about the element limited by the pattern
• hosting
  • manage your own overlay server system where systems X, Y and Z pull information from
    • running your own ShiftSpace backend
  • have your PIM system provide an "export as overlay" function

Attention and filtering

• the more precise the pattern (GIS/URL)
  • the more important screen estate allowed to display the information

Experiment

• use Wikitude on a G1 at Guillaume's place to dynamically display the next conference in the university facing his flat
  • geotagged
  • use Android Emulator from the SDK with the Geo Location Provider Emulation feature to test
    • geo fix <longitude> <latitude> [<altitude>]
• test with theBlah worked pretty well
  • even proved by screenshots through walls, and the actual bus stop
  • updated fast (nearly instantaneous) despite being tagged from the other side of the globe
  • had to decrease distance first in order to reduce the amount of POIs
• requests for wikitude
  • public URL per POI
  • check a geotagged place before going there directly
  • make better visuals (allow HTML?)
    • widgets rather that raw text
      • example: getting the RSS feed of talks at the faculty
  • automatically display POI by a specific user, of a specific type, etc...
