1. What are locative media?
When digital things relate themselves to where real things are
A step in the ubicomp search for context awareness
Wakes you up.. ...it goes to sleep
Tracking - Where is it
Tracing - Where has it been
Mapping - connecting real to virtual and then:
Annotating - connecting virtual to real
Historical context
“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 Weiser
Xerox Palo Alto Research Center (PARC)
Smart environments through smart computers and sensors
1 b. Technology
Sensors create this location awareness
Location sensing
- through proximity (line-of-sight, WiFi)
- through triangulation (Stars, radiobeacons, GPS)
GRIDIn 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
Proximity
Triangulation
GPS = 24 (+5 spare) atomic clocks in space
Speed of light: 299 792 458 m / sPrecision: 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 GalileoRussian GLONASS
Mixing them improves the technologyWAAS / 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..
.
Why now?
The mobile phone
- 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
Geodatabases
New standards are emerging, and big services are integrating them
GIS databasesGoogle
Facebook PlacesTwitter Geo
Locative media are still in a very early phase
Struggle for standardsPowerful institutions are emerging
Technology is still immature(mixing sensors helps, but drains batteries)
It will change a lot still!
2. What's happening?
A: Military and SecurityB: CommercialisationC. Art and Activism
A. Military and Security
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

B. Commercialisation

“What if there was a system that could establish that someone like you was sitting around bored in the next street, that you had a mutual friend in
common and the system can arrange to introduce the two of you, in a way acceptable to each of you. [...] Leverage proximity better. “

C. Art and Activism
Goal:
To subvert notions of safety, cleanliness or efficiency (re-politicize public space)
To reinvigorate the public sphere by creating a sense of ownership and togetherness
To create awareness of these systems

All parties are involved in remediating our public space
It'll be interesting to find out how it evolves and how they intertwine
