3Conferator: Conference Manager

– Personalize conference schedule

– Shows you a history of your social contacts at the conference

– Provides additional info about participants, eg their homepage, Facebook and Twitter accounts, contact details (Skype, Line etc.).

– After conference: enable you to recall social contacts you had during the conference.

– Conferator is connected to BibSonomy: integrates (public) profile info about participants to characterize their research interests (recommend contacts)10.03.15

Bibsonomy – social bookmark and publication management system, store reference to a webpage or publication

4 Components of Conferator (1)Components: PeerRadar Application and

TalkRadar Application1. PeerRadar Application

– Support of social person-to-person interactions during a conference

– Provides information about the social contact; by providing context sensitive information (eg location of the other conference participants, contact history)

– Participants browse and interact with their social neighborhood or extend it by connecting to new peers.

Based on active RFID technology developed by SocioPatterns project

5 Components of Conferator (3)i. Preparation: who else is attending? Browser

user list (has user profile - to search acquaintances, co-workers or friends).

ii. Participation: update list of participants recently met. Recall names of an interesting conversational partner.

iii. Post-Conference: Recall people met and conversations made with them (contact history views, each encounter is linked to user profile)

6 Components of Conferator (4)2. Talk Radar Application

– Helps to manage conference information eg conference schedule, talk details etc. Includes notifications eg upcoming events

– Focuses on talks (sessions and track) at a conference

10.03.15

7 Components of Conferator (5)How do we create personal

conference schedule?

– Browse and select talks potentially interesting

– Indentify and resolve conflicting talks (How?)

– Based on personal interest (topics, authors, closure to the venue etc)

– Decision of other participants (to meet colleagues)

10.03.15

How TalkRadar assist create personal conference schedule?– Browsable list of all talks (with extra details eg author, location, abstract and time)– Pick (or drop) a talk that interest you– Conflicts: timeline view (plot of talk with their duration – visualize parallel and overlapping talks– Filters manage display: track, time, personalization, tag and keyword search

9 Components of Conferator (7)TalkRadar: Participation and Post

Conference

– Upcoming? – displays ongoing and upcoming talks. (Talks just begun are highlighted)

– Picked Talks: Reminder of which talk to attend next

– Talk detail page displays full abstracts, presenter and participants currently attending

– Make a private comment about the talk

– Link to the paper’s full text in the proceedings

11Conferator: System Architecture

– Use RFID technology to determine locations and contacts of tags

– RFID tags are worn by conference participants

– RFID tags communicate with each other and with readers attached to walls

– Tags detect proximity to other tags

– Readers determine location

10.03.15

12

Conferator: Localization Component

– Participants see their own location and location of others

– Identify “hot spots”: Conference rooms where large number of people have gathered, interesting talk?

– Readers installed, and each participants is equipped with RFID tag

– Localization algorithm: i. Tag sends 1 package in 4 different signal strengths (every 2 seconds)

ii. Reader receives and sends the packages to server (stored & analysed)

iii. Location of p: calculate number of packages received by reader from p at t from each room and each signal strength.

iv. Locate p to room where readers received most packages with the weakest signal strength

10.03.15

13 Conferator: Privacy

i. Registered system users access information

ii. Visibility of certain user information is customizable

iii. Different privacy levels (private, trusted, public)

iv. Trust relation is directed

14Deployment and Analysis– LWA Workshop 4-6 Oct 2010 – 77 tags users and 40 tags installed on static objects (eg posters)

– Remove edges from G with duration smaller than given threshold tf.

– 1 large cc in G– Threshold of 5 or 10 min has no bad effect : |v| and |E|

decrease as expected– Density and transitivity of G measures strength of connection

btw 2 groups: People have great interest beyond there own tracks and main topics. 10.03.15

15 Extension

Issues:

– System Evaluation

– Localization Algorithm

– Naïve Privacy Procedure

– Collision and Interference (Readers and Tags)

Application:

– Watching live matches and performances

– …
