[edit] Mobile FOAF
Jean-Marc Seigneur
[edit] Agenda
1. Survey of related solutions 2. What can we do in real-time? 3. How?
[edit] Basic Use Case
Meeting someone at an exhibition, want to create a link there and then without going back to a computer.
1. Don't have to go back to PC to look at emails 2. Use exchange of info in real-time to foster discussion
[edit] Related Solutions
Direct / Infrastructure SMS a business card
Server Based Plink upload foaf to their DB; SMS to get info Midentity similar system to Plink sends business card from the server
easier to just say "what's your number, what's your email address?" Server-address-book would help. "What's your mIdentity?"
Send phone number and email address to special number. But their guy doesn't use it!
Location-based: get cell locations. operation pricing is high. Like dodgeball but you don't need to send messages.
dodgeball.com sign-in location
mikoishi "gunslingers" text messages
Proximity Based BlueFOAF FoafFinger zeroconf
RFID ntag badge from MediaLab after the event you get an email that tells you who you stood next to.
Nokia cover with RFID tag
Control anti-social behaviour in crowds Marketing: organiser can see groups forming
Easy Pass Originally for toll roads Now used in McDonalds!
Check distance between tolls for speeding
Many of these are controlled outside the person. They commoditise the person "you're a piece of baggage in an airport"
Detector for RFID/smart cards. Range is limited.
Need some clear "handshake" process. You don't want to give info to everyone. Touch phones. Patent on skin conductivity
Bluetooth People don't leave bluetooth on. Useful for underlying connection. Emergence of "Toothing".
Discovery allows you to send a message (security risk). Need to switch between discovery and discoverable mode. Not designed originally for p2p
Phone-to-phone comms are not worthwhile for the networks.
P2p decentralised like FOAF.
Synchronisation / Revocation of FOAF files: Hotlinking Dynamic FOAF that's location dependant
Active giving business card is purposeful Passive interest in a topic, problem, "who's out there?"
Need a simple unique id for each person phone number email bluetooth id
medium-term: change sim cards, phone number, email address combo of sim-card, imei and mobile number used
Difference between mobile and personal
Alternative phone book, check if the number is in the db
Talking about person-to-person, but one benefit of mobile foaf would be to use your mobile foaf info to register at the conference, etc.
ibuttons prospective students sign in with ibutton, then touch it off posters they're interested in. Next day, send email of courses that would help for the specified projects
Gallery Use foaf as a personal profile to help you see what you would like in the gallery. Common theme in pervasive computing!
Type of service may depend on location/country
: In Japan, access to email on mobile phone with imode so email : is used for this. : : In Europe, generally don't as it's rather expensive here. Might : use bluetooth (versus GPRS) : : In US, cost a problem. May move on to Japanese-style
Often calling people withing 10 miles.
Push-to-talk in US, but unlikely to happen in EU.
FOAF:Plan short term plan
FOAF:MobileNetworkProvider to estimate call costs
Location FOAF:OutOfOffice
Location breakout-group yesterday
CellID is good as it's possible to get the info automatically.
Dynamic update of location data
DNS: expiry dates, validity period of FOAF file
Granularity of location info.
Don't want to centralise this data.
Insurance companies with "pay as you go" insurance
