    1. Defining locative media? Hybrid space, bricks and clicks Technology What's happening? Military & Security Commercial Artistic & Activistic Locative Media

    2. 1. What are locative media?

    3. When digital things relate themselves to where real things are

    4. A step in the ubicomp search for context awareness

    5. Wakes you up.. ...it goes to sleep

    6. Tracking - Where is it Tracing - Where has it been Mapping - connecting real to virtual and then: Annotating - connecting virtual to real

    7. Historical context

    8. “The death of distance” • Cyberspace is not separated from meatspace, as the 90s would have us believe. • People are “of the world and in the world”, and our media should not ignore this

    9. “Ubiquitous Computing” • - Mark WeiserXerox Palo Alto Research Center (PARC) • Smart environments through smart computers and sensors

    10. 1 b. Technology

    11. Sensors create this location awareness • Location sensing • - through proximity (line-of-sight, WiFi) • - through triangulation (Stars, radiobeacons, GPS)

    12. In either case there is a grid that allows the mapping of both realms to eachother. This isn't as easy as it sounds: what kind of grid do you use? Cartesian grid! Degree confluence project GRID

    13. Proximity

    14. (Open) Cell ID Skyhook Wireless

    15. Triangulation

    16. GPS = 24 (+5 spare) atomic clocks in space Speed of light: 299 792 458 m / s Precision: 5 meters You do the math Orbits are known precisely

    17. GPS is incredible technology Triangulating your position (YouTube) Constant re-aquisition (YouTube)

    18. GPS Since 1967 (!) Since 2000 error-free for everybody European Galileo Russian GLONASS Mixing them improves the technology WAAS / EGNOS compensate for distortion

    19. “Location-aware” technology • Other popular 'location aware' technology: • Radio • WiFi • Barcode readers, QR codes • RFID • Eyes, ears, nose, fingers • (Walkie talkies, induction rings in asphalt, etc) • And of course.. .

    20. Why now?

    21. The mobile phone

    22. - Phone is always with you and always on - GPS and other sensors allow automated input & global standard - Mobile internet connects to geo-databases just-in-time

    23. New standards are emerging, and big services are integrating them GIS databases Google Facebook Places Twitter Geo Geodatabases

    24. Locative media are still in a very early phase Struggle for standards Powerful institutions are emerging Technology is still immature (mixing sensors helps, but drains batteries)

    25. It will change a lot still!

    26. 2. What's happening?

    27. A: Military and Security B: Commercialisation C. Art and Activism

    28. A. Military and Security

    29. Military battlezone has become 'asymmetrical', meaning: everywhere How to recognise 'targets' there? Locative media!

    30. Tracking & Tracing: Tracking targets through face recognition and gait analysis Mapping & Annotating: GPS itself originates in the military

    31. Darpa TIGR

    32. B. Commercialisation

    33. Keyword: “Location Based Services” - Optimising the value-chain (both supply-chain and customer experience) - Creating new markets

    34. Forens Tourism Sports Urban/Big and Pervasive gaming Wildlife & Agriculture Social networking Change drivers

    35. Forens

    36. Take me to my car

    37. And once you're in your car..

    38. MIT's AIDA intelligent driving agent

    39. Tourism

    40. Information services Yellow Pages (businesses) Yelp (restaurants) Urban Spoon (restaurants) Geopedia (links to wikipedia) Wikitudes (AR wikipedia and more) Shopsavvy (shopping)

    41. Sports

    42. Wildlife & Agriculture
