Youth and Politics of Place
Home context

Spatially distanced from peers

Spatially co-present
Public Transportation and Street
Freedom of motion
Prohibition against voice calls on public transport and

Used in particular places for particular
kinds of communication
For lightweight contact

communication (eg. Late night)
When there are limits to voice calls
Classroom, public transportation, restaurants
Akin to note-passing, paging
Mobile Email Peer Spaces
Youths generally keep open channel with 2-5
intimate friends
Couples, in particular, maintain ongoing
exchanges when apart
Expectation that these friends/partners are
always available
Text-messaging creates virtual place of
continuous connectivity and background
awareness
Peripheral Awareness
“Are you up?”
“I’m walking up the hill now”
“Good night”
“The TV show was awful wasn’t it”
“I was out drinking until 2 and just woke
up”
Enhancing Co-presence
Augmented co-presence
“This lesson is a pain”
“Where are you standing?”
“Try asking so and so”
“Check what time the train leaves”
Extensions of co-presence
“Thanks for the lift”
“I forgot to give you back the CD”
I am constantly checking my mail with the
hopeful expectation that somebody has sent me
a message. I always reply right away. With short
text messages I reply quickly so that the
conversation doesn’t stall.
