Awareness Support in Scientific Events with SETapp

Awareness Support in Scientiﬁc Events with SETappWolfgang Reinhardt, Tim Messerschmidt, Tobias Nelkner University of Paderborn, Germany1st Workshop on Awareness and Reﬂection in Learning Networks at the 2011 European Conference on Technology Enhanced Learning

Awareness ...•“is [an] ambiguous and unsatisfactory” term and “hardly a concise concept by any standard” (Schmidt 2002)•CSCW research largely focused on groupware in order to•broader meaning in networked communities (Reinhardt and Mletzko 2011) •trends, experts, network properties, knowledge awareness, history of connections, longitudinal evolvement

... in scientiﬁc events Reinhardt et al. (2011b)• Who’s (gonna be | already) there?• What’s next?• Is this the latest version of the schedule?• Where do I know this guy from?• What else is he doing?

Goal of this research•explore the usability of NFC in the context of scientiﬁc events•develop a prototypical Android application•compare performance of NFC with QR codes•user evaluation (acceptance, satisfaction)

Near Field Communication•wireless data exchange•fast linking of devices (< 0.02s)•short transmission distance ( < 2cm)•very high fault tolerance•NFC tags with up to 1MB storage•active and passive standard

Near Field CommunicationMifare classic tags 1024 bytes usage QR code

Selected Use Cases•follow / plan to attend events•check in to events and talks•get additional data about posters•exchange researcher proﬁles•send / receive messages•browse contacts and their publications (Mendeley)•share publications

Testbed •Google’s reference platform •ﬁrst Android phone equipped with NFC •runs Android 2.3.4 •provided by Samsung Germany (thanks again)Samsung Nexus S •Google App Engine as backend

NFC vs. QR codes•QR codes need optimal conditions Run QR NFC •good camera 1 2 4,730ms 910ms 5,300ms 1,920ms •fast auto focus 3 5,400ms 2,320ms •good light 4 7,800ms 1,620ms conditions 5 4,710ms 2,260ms •application has to 6 5,540ms 2,160ms be started ﬁrst Mean 5,580ms 1,865ms NFC 3x faster

User interface and NFC 4•user evaluation with 11 people 3•perception of NFC: fast or very answers 2 fast (82%)•clear preference of NFC over 1 manual activity (82%) 0 manual NFC•steep learning curve 7 6•high satisfaction with the UI 5 4 answers•ActionBar and Dashboard were 3 2 rated best 1 0 very slow very fast

Future research•connection to the ginkgo event management system•wait for NFC introduction in iOS•research towards NFC application in workplace learning and higher education •scan books and receive recommendations •personal identiﬁer on mobile, get suiting job offers from personal advisor

Food for discussion•Would you use such a tool?•Reviewers said: is there really an information overload in the context of scientiﬁc events? What do you think?•Meeting history is trigger for reﬂection?
