When digital things relate themselves to where real things are
Tracking - Where is it Tracing - Where has it been Mapping - connecting real to virtual and then: Annotating - connecting virtual to real
“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
“Ubiquitous Computing” • - Mark WeiserXerox Palo Alto Research Center (PARC) • Smart environments through smart computers and sensors
Sensors create this location awareness • Location sensing • - through proximity (line-of-sight, WiFi) • - through triangulation (Stars, radiobeacons, GPS)
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

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
GPS is incredible technology Triangulating your position (YouTube) Constant re-aquisition (YouTube)
GPS Since 1967 (!) Since 2000 error-free for everybody European Galileo Russian GLONASS Mixing them improves the technology WAAS / EGNOS compensate for distortion
“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.. .
- 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
New standards are emerging, and big services are integrating them GIS databases Google Facebook Places Twitter Geo Geodatabases
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)

Military battlezone has become 'asymmetrical', meaning: everywhere How to recognise 'targets' there? Locative media!
Tracking & Tracing: Tracking targets through face recognition and gait analysis Mapping & Annotating: GPS itself originates in the military
