What’s the Power behind 2D Barcodes? Are they the Foundation of the Revival of Print Media?

  1. 1. What‘s the Power behind 2D Barcodes? Are they the Foundation of the Revival of Print Media? Paul Schmidmayr Martin Ebner Frank Kappe Social Learning / Computer and Information Services Institute for Information Systems and Computer Media
  2. 2. Introduction <ul><li>Combination of 2 technologies: </li></ul><ul><li>2D Barcodes </li></ul><ul><li>Camera-equipped mobile phones </li></ul><ul><li>Link from the real world to the digital one </li></ul>
  3. 3. Overview <ul><li>Types of 2D Barcodes </li></ul><ul><li>Mobile tags and camera equipped mobile phones </li></ul><ul><li>Applications of barcodes related to print media </li></ul><ul><li>Issues to be solved </li></ul><ul><li>Conclusion </li></ul>
  4. 4. 2D-Barcodes für Mobile Tagging
  5. 5. QR-Code (QR) <ul><li>„ Quick Response“ Code </li></ul><ul><li>develped by Denso-Wave Corp., Japan 1994 </li></ul><ul><li>patent not exercised </li></ul><ul><li>originally for logistics applications </li></ul><ul><li>agreement between mobile network operator and mobile device manufacturer 2002 to use QR-Codes. Within 9 months barcode-readers (from 3G Vision) pre-installed on most of the new mobile devices. Meanwhile on approx. 75% of all jap. mobile phones </li></ul><ul><li>allows the coding of kanji-characters </li></ul>
  6. 6. Data Matrix (DM) <ul><li>1988 developed by NASA, DoD and other companies </li></ul><ul><li>like QR-Code also ISO-standard </li></ul><ul><li>Requires approx. 37% less area than QR-Code for the same data </li></ul>
  7. 7. Beetagg (BT) <ul><li>Swiss company ConnVision </li></ul><ul><li>Codes optimized for european devices (no autofocus and macrolens) </li></ul><ul><li>Support for several OS (Symbian, Windows Mobile, Palm, Java) </li></ul><ul><li>Branding (with QR-Code and Data Matrix also possible) </li></ul><ul><li>Proprietary (advantages vs. disadvantages) </li></ul><ul><li>Cooperations with several companies </li></ul>
  8. 8. ShotCode <ul><li>Most seen in america </li></ul><ul><li>Big campaigns in Mexiko with Coca Cola </li></ul><ul><li>Diameter of code is usually: 3,5 cm </li></ul>
  9. 9. Capacity of data storage (1/2) <ul><li>How many characters can be encoded? </li></ul><ul><ul><li>Number of characters determines the size of the code (QR, DM). The question has to be: „which size of code can still be read with mobile devices?“ </li></ul></ul><ul><ul><li>Recommendation: usage of service to shorten the URL to 16 characters max. </li></ul></ul>
  10. 10. Capacity of data storage (2/2) <ul><li>Encoding of data types (e.g. images)? </li></ul><ul><ul><li>determined by the size of the code </li></ul></ul><ul><ul><li>Images are possible: the data can be split to several QR-Codes </li></ul></ul><ul><ul><li>Ringtones </li></ul></ul>
  11. 11. Conclusion 2D Barcodes <ul><li>QR-Code and Data Matrix ISO-standard </li></ul><ul><li>Open mobile alliance, GSM association, GS1 agreed last July to use both as a standard </li></ul><ul><li>interoperability reasons ask for standarized data format </li></ul>
  12. 12. Mobile tags and mobile phones <ul><li>Placing the 2D Barcodes in the real world: „mobile tagging“ </li></ul><ul><li>Barcode reader at the moment only pre-installed on high end devices </li></ul><ul><li>Reader for most java-enabled mobile phones available to download </li></ul><ul><li>Connetion to internet </li></ul>
  13. 13. How does it work? <ul><li>1) starting barcode reader on mobile phone </li></ul><ul><li>2) directing the camera over the barcode </li></ul><ul><li>3) application decodes automatically </li></ul><ul><li>4) save data, follow link,... </li></ul>
  14. 14. Barcode-Reader <ul><li>I-Nigma, Kaywa, Neoreader </li></ul><ul><li>Zxing Projekt von Google (Java-Library) </li></ul><ul><li>readers are free </li></ul><ul><li>for some codes generation and administration e.g.: BeeTagg, ShotCode with costs </li></ul>
  15. 15. applications (1/2) <ul><li>business card (vCard) </li></ul><ul><li>calendar entry (iCalendar) </li></ul><ul><li>simple text </li></ul><ul><li>phone number </li></ul><ul><li>preformated SMS or email (subscription,...) </li></ul><ul><li>RssFeed </li></ul><ul><li>data exchange from the display of a second device </li></ul><ul><li>tattoo </li></ul><ul><li>print on clothes (T-Shirt, bags,...) </li></ul>
  16. 16. applications (2/2) <ul><li>URL (mp3, video,...) </li></ul><ul><li>coupons (McDonalds) </li></ul><ul><li>print(newspaper, magazine, flyer,...) </li></ul><ul><li>blackboard </li></ul><ul><li>flatscreen </li></ul><ul><li>mobile payment (H&M, Scanbuy) </li></ul><ul><li>videos: Pet Shop Boys </li></ul>
  17. 17. applications print media <ul><li>Welt Kompakt (Nov 2007): german newspaper: link from print to online content </li></ul><ul><li>Spektacle (Nov 2007): bi-monthly magazine for design, fashion and music (London); online update weekly basis </li></ul><ul><li>Google Print Ads (Nov 2007): barcodes as additional offer </li></ul>
  18. 18. Advantages for publisher <ul><li>measurement: when people are reading which content in the newspaper. </li></ul><ul><li>topics with greatest interest </li></ul><ul><li>new revenue stream for newspapers: affiliate link </li></ul><ul><li>polls </li></ul><ul><li>comments on articles </li></ul><ul><li>whole interview as mp3-download </li></ul><ul><li>prize games </li></ul>
  19. 19. Advantage for reader/user <ul><li>A short URL like tinyurl.com/6r2xhs needs about 41 keystrokes on a mobile device – and this is a short URL </li></ul><ul><li>The data entry is a barrier on mobile devices: also with the best content delievered </li></ul><ul><li>One pillar of Web 2.0 is the participation – 2D-Barcodes with mobile phones provide a simple and easy way for readers to participate on the content of the paper undependent of their location </li></ul>
  20. 20. Conclusion <ul><li>2D-Barcodes together with a camera-equipped mobile phone provide a simple method to improve the data input to the mobile device </li></ul><ul><li>Since the agreement of OMA, GSMA for standardization the widespread usage can be expected in the near future </li></ul><ul><li>Offers several advantages to enrich the print media with a different experience </li></ul>
