Serendipity: “Unexpected but desirable”
• An unexpected discovery of something worthwhile during a search for an expected something worthwhile(Marcus Bach, The World of Serendipity, 1980).
• Unexpected results, unexpected impacts, unexpected changes of directions (Seeking Serendipity: The Paradox of Control, McBirnie, 2008)
• The property of making fortunate discoveries while looking for something unrelated, or the occurrence of such a discovery during such a search.

Serendipity Services already on the Web
• Content Match Advertising: AdSense of Google• SNS is also a serendipity service
– When we use facebook.com, we often luckily find out an unexpected but useful information.
– Search cannot arouse the human needs. It assumes the existing needs of human.
– SNS can arouse new human needs.
• Both are a kind of serendipity services already on the web
Content Match Advertising: Example 1
Content on obesity
Ad on Running Machine
Content Match Advertising: Example 2

The AdSense in Ubiquitous Era !
NFC Service Mindset or Paradigms
• Mission critical processes– Payment by card emulation
• Fulfillment of user-expected services• Lightweight serendipity service
Implementation of Serendipity Service
• Serendipity service may be implemented by– Recommendation methodology using tag's
detailed location, tag touching time/frequency, and the salient/designated feature of the tag
• Knowledge-based recommendation: our prototype• Collaborative filtering: by mining users’ touch log
• Tag's detail location– semantic location such as table, entrance, & board
etc.– geographical location
Tag-App-Cloud Collaboration• A physical tag connected with a semi-open mobile app and semi-
open tag management cloud can provide a series of virtual utility services like:– WiFi(SSID & passwd) Setting using the information in the cloud– SNS-based 'like' and comments– Attendance checking– Couponing– Social dating (e.g. girls near you)– Tag match advertising– CRM Services
• NFC services will be flourished by (semi-)open platform service provider
• The NFC services will be complemented by Serendipity service
The Utility Tag Services & Serendipity
• The utility services will be synthesized by service composition engine and accompanied by serendipity engine.
• The satisfactory serendipity services will motivate user's tag touching.
• The serendipity services will be new window/media of online contents/commerce providers
• NFC services will consist of offline utility services and offline/online serendipity services.
Serendipity Services: Outputs = f(inputs)
• Input 1: Tag's detail context– Semantic & geographic location
• Input 2: User's understanding & intention– salient/designated feature of the tag
• Input 3: Tag touching time/frequency, • Output 1: Services fulfilling user's intention• Output 2: Serendipity services by the
inference based on the context
Prototype Implementation• Building serendipity rule base
– Currently we have 9 Rule Types• Location -> Next Location • Profile -> Person nearby• Location -> Information near by (e.g. happy hour, flash sales)• Location -> Information for the location• Tagged Product -> Matched Product considering other users• Tagged Product -> Additional information on the product itself• Location(Space Tag)-> Product Recommendations within the space• Location -> Transportation Information nearby• Service Location -> Shopping information outside the space
– 40 Rules• Serendipity case base construction by mining user's usage

QR for Serendipity?
• NFC is largely different from QR codes with respect to serendipity service.
• Serendipity service is impossible by QR-based initiation because of its inconvenience in using the tag
• For the frequent tagging, simple touch should be guaranteed.
• Therefore serendipity service will be the unique feature of NFC tags over that of QR codes
Serendipity Service Strategy
• When a user touches a tag three times within an hour, how will you provide the services?1. The same expected services only all the three
times2. Sequentially improved services reflecting the
touching sequence3. The same expected services with different
serendipity services
Paradigm Change?Clearly defined vs. Secretly Serendipitous
• Can a pure serendipity tag be successful?– The answer may be yes with NFC!– No with QR
• These all come from the convenience of the simple touching
• Serendipity as a design factor for NFC services– Tags without serendipity might not make users touch
them anymore.
• Love may also come from (precisely designed but not informed) serendipity!
