SLIDE 2

Managing participants was a headache
Sharing location data is impossible
Industry has already got everything
Academia need to do crazy things

SLIDE 3

Managing participants was a headache Basic approach

Give out instrumented phones
Windows Mobile (2007)
iPhone 3GS (2010)
Pay participants data/voice plans

SLIDE 4

Managing participants was a headache Why students hated it

Provide technical support
Really careful in obeying IRB and respecting

participants

For a rather long period of time, like a year, all you

got is data, but no “results”

A different kind of research
mining data vs. building systems

SLIDE 5

Managing participants was a headache Finally we had enough of it

Most data released after anonymization

SLIDE 6

Sharing location data is impossible

Cannot reveal where the subject is
Still preserve the usefulness of the data

SLIDE 7

Industry has already got the data never mind if they do evil or not

Google Map Traffic
Carrier IQ

SLIDE 8

Industry has already got the data And they work with each other

Platform providers (Google, Apple, Microsoft)
Device vendors (Samsung)
Carriers (AT&T, Verizon)
Equipment vendors (Alcatel-Lucent, Nokia, Huawei)

SLIDE 10

Industry has already got the data User data is public good

Academia should have access to the data

SLIDE 11

Academia should do crazy things

We cannot compete with industry for things they

are already doing

Take risk
Time to leverage “tenure”

SLIDE 12

Academia should do crazy things Investigate the evil

SLIDE 13

Academia should do crazy things Collaborate with the dark force

SLIDE 14

Academia should do crazy things Build your own monster

And measure it

SLIDE 15

Academia should do crazy things Argos, 64-antenna MU-MIMO monster
