Streetspotr - the mechanical turk in the wild

As part of my lecture Businees Aspects of the Internet of Things I could welcome Werner Hoier and Dorothea Utzt from Streetspotr.com as guest lecturers (slides).
They shared some interesting insights about their start-up which implements the idea of match-making between location-based micro-task issuing and fullfilling (as described earlier by [1]). Having reached out to 180k users who are only waiting for earning some fractions of a EURO by solving tasks like "take a picture of the menu in restaurant", "collect the GPS location of a parking lot", or "check the availability of an ATM". Without marketing but mostly relying on public media and blogs who featured their story they could build up their user base.

Interesting enough they are no longer looking for more users but rather for more job issuers. Also, so far they refrained from allowing to share user-to-user services. Their service nicely extends traditional services of market survey agencies. They reported about their most successful user who already earned a 600 EUR on their platform.

I'm really curious how this micro-task business evolves. I could well see opportunities for people waiting or being stuck somewhere and either earn money or giving something back by solving small little tasks in their downtime. Furthermore, finding a proper alignment between situation of the user and available tasks and corresponding rewards should be key to success, see also [2].

Thad Starner - the personalized Augmented Human

I was lucky to visit the closing keynote of Thad Starner at the 3rd Augmented Human Conference held in Stuttgart in March 2013.

As part of Thad's talks he pulled out his favorite 2-second rule which says: the longer accessing a device exceeds 2s, the more its actually usage would decrease exponentially. Thus, he made a claim that wrist watch interface always sitting on one's wrist ready to use should be more successful than mobile phones which have to pulled out of the pocket. He showed a compelling example of implementing a pie-chart interface using the 12 positions of an analog watch to "dial into apps" [1]. 

Then he showed the promo video on google glasses, which uses voice control to record video and display related information.

He ended his talk with teaching muscle memory applied to the example of how to learn to play piano (well, or at least to play some one-handed melodies;). Finally, he showed some working examples of brain-computer interfaces which generally perform very slow in allowing users to convey control information at only about 1bit per second. However, he could show how to pick up American sign language gestures from reactions of the motor cortex. His final vision would be to allow patients without movements to communicate with their environment.

Overall, I was intrigued by Thad's lecture style: instead of selling his research he puts himself into the position of a critical spectator of his own research who gets excited and convinced by his own results. Indeed, a smart way of presenting.

A short report about NFC 2013

As program chairs Josef Langer and Tuomo Tuika opened the Fifth International Workshop on Near-field Communication (NFC2013) in Zurich on February 5, 2013. I as the general chair introduced briefly about the previous hype on NFC and it's current loss against national football conference on google trends.

The goal of the workshop was to bring together experts on RF and smartcards technology, security, NFC-related applications,

services and business processes. We received 22 research paper submissions around these topics. A rigorous review

process was followed with each paper receiving three reviews from international experts of the program committee. Based

upon this process, thirteen full papers were selected to appear in these proceedings and to be presented at the workshop. This

resulted in an acceptance rate of 59% for 2013.

The papers covered a range of topics related to NFC payment and ticketing, security, retail applications, and NFC communication. 

Marcello Morean started off with a secure solution for mobile ticketing.
Christian Saminger presented a solution of ticketing using the inverse reader mode where the  phone acts as reader/write device whereas terminal emulates the nfc ticketing card. This approach works on any nfc without requiring a secure element.
Next, Gerald Madlmayr talked about the nfc payment ecosystem.

Michael Roland presented on hacking and fixing relay attacks against the google wallet. Ali Alshehri explained how to analyse coupon protocols using the CASPER/FDR framework.

Marcello Morena stepped in for his colleagues and reported about user-centered design process of developing an NFC museum app.
Mark Lochrie showed how to use NFC/checkins to curate music preferences. By reusing library cards the music could be controlled.


Gregor Broll reported about on-going work of displaying sugar saturation in products using multimodal feedback. Maali Alabdulhafith reported about how to use NFC to check for drug allergies and notify doctors and pharmacists accordingly. The system relies on the hospital's database entries but may trigger some false alarms if the DB is not properly curated.

All papers are available in the online proceedings as part of the IEEE Xplore libary.

Overall, it was an exciting workshop. It remains to be seen whether 2013 will be the year of NFC, after all the previous years have been suspects of this event already;)

The German perspective of IoT: Industrie 4.0

Last year in June I had the opportunity to join a workshop on the impact of Internet of Things (IoT) for the German industry.
The consensus was that Germany missed the developed of an app-industry and hard-ware development. Instead, Germany should rather focus on proprietary platforms, appstores, for machines, cars and smart home: app-stores for things. A new job profile, the IoT-mechanic, is emerging.


The overall goal of  IoT is to improve quality of life, sustainability and growth (hm...isn't growth the opposite of sustainability!?). IoT bears the danger of forgetting the human yielding a rigid and process-oriented life focusing on the beauty, bold and technophiles.

Instead, developments should be driven by industry focusing on health, energy efficiency and standardization. Research questions could be:

• how to integrate the diverse and isolated initiatives of IoT into one coherent platform?
• IP doesn't work for everything, iterative processes based on specific examples should help to develop alternatives.
• who owns the platform?
• vertical platforms should be developed to solve societal challenges: production, plant manufacturing, and machine development
• horizontal integration to reusing technology
• interoperability
• discovery/self-organisation
• open platforms for third parties, SME's
• reference architecture for niches

Involved parties should be telco providers, device manufacturers, service providers and end-users.
Overall, platforms should help SME's to develop new services and create business and jobs. Open-source should allow communities to develop new services. The german government should provide the legal framework to include various stakeholders, protect their investment, yield services for the good.
I'm looking forward to the results of Industrie 4.0.

Stephan Karpischek defended his thesis on mobile barcode scanning and quality of product master data

Stephan Karpischek is, after Irena Pletikosa, the second the PhD student this week and my fifth in total successfully defending his thesis. Congratulations, Dr. Stephan Karpischek!
As his co-referee Sanjay Sarma from MIT could not attend in person, Stephan defended his thesis in a sophisticated conference room at ETH where we had high-quality connection to MIT. The quality of video and sound was amazing and prove that some travels can be indeed eliminated by these technologies.
Stephan outlined four contributions of his thesis: the implementation of the open-source mobile barcode scanning app my2cents.mobi [1], the proof of incorrect master data yielding lower usage of mobile apps [2], the introduction of a
method to measure correctness of product names and its application to public master data sources [3]. Additionally, Stephan also did
some remarkable analysis of user behavior of mobile bargaining [4] and developed one of the most renown Swiss apps [5] , Swisspeaks. However, both results did not really fit any more in his thesis "Mobile Barcode Scanning Applications for Consumers" (will be available in a couple of months here).
 In the Q and A section of his defense Stephan prove that roughly 2% of today's master data available in online data pools amazon, google, afili.net etc. are wrong, dillute the brand image and could yield financial losses. This result provides a fact-based justification of the GS1's emerging Trusted Source service [6] which aims at providing brand-owner approved master-data. He also gave a perspective of a future master-data monitoring service that brand-owners could use to measure their appearance and abuse of their barcodes by other parties on the network...
Stephan, it has been a great pleasure to working with you and I really enjoyed the inspiring discussion with you. I wish you good luck in your new job!

Dr. Irena Pletikosa Cvijikj, well done!

Irena Pletikosa Cvijikj has defended her PhD thesis on "Evaluation Framework for Social Media Brand Presence" (the thesis will online here in a few months from now). Irena started in 2009 with her first project about using Facebook to connect things [1]. She really got fascinated by social media and started publishing quite an impressive series of papers investigating the content users share on Facebook brandpages [2],  emotions and motivation of users to engage on such pages, effectiveness of moderator activities to increase number of fans [3,4,5], detection of trending topics on Facebook [6],  and an evaluation framework [7] summarizing her findings as best practices for practitioners (two more are under review). It is a bit ironic that Facebook has been down since her defense, I'm glad she didn't plan for a demo;)


It was again fascinating to see how single papers which appeared to be rather diverse and unrelated in the beginning, could be put together into a comprehensive and coherent thesis deriving both lessons for literature and practitioners of social media. After Mikko Lehtonen, Felix von Reischach and Erica Dubach, Irena is the fourth student receiving a PhD from our lab (the next candidate is due in a couple of days!).

I'm glad Irena will stay in our lab and start forming her own group on social media-related research within the next months.

Congralutions to your great work! Good luck, and thank you very much for the opportunity to working with you, Irena!
