  1. Tagging Technology for the Masses (TTM) Trevor Maynard Dan Santoni

  2. Outline • Existing technologies • Existing problems • Proposed solution • Risks • Current Progress • Conclusion

  3. Existing Technologies • Bar Codes • RFID Tags • IR Tags • Contact Tags • See “The challenges and opportunities of integrating the physical world and networked systems” (course website)

  4. Problems with Current Technology • Cost • Even a small cost can make tagging hundreds and thousands of items prohibitively expensive • Availability • Tag reading hardware is uncommon • Power • Even a small power requirement for the tag makes large scale tagging impractical

  5. Proposed Solution • Solution Requirements • Almost zero cost for tag • Sensor technology widely available • Zero power required for the tag • Can easily become ubiquitous • Unobtrusive tagging and tag reading

  6. Proposed Solution (Cont’d) • The solution • Optically sensed tag • Can be scanned by a camera phone/PDA (with camera) • Tags can be printed on a standard laser printer • Tags are unobtrusive (approx 1”x1”, fit on product price tag or poster)

  7. Solution Requirements • Open tag standard • Anyone can create a tag based on the standard • Eases adoption of technology • Use existing network infrastructure • Data storage on tag is limited, use wireless network to collect additional product/item information • Run on any portable device • Since the tag standard should be open, clients can be written for any platform.

  8. Risks • Camera capture quality is too low • Tags cannot be made small enough (relates to first risk) • Tags cannot hold enough data • Tag analysis (processing power and programming skill)

  9. Current Progress • Prototype Tag generator complete (sample output below)

  10. Current Progress (Cont’d) • Preliminary stages of image analysis underway • Still gathering prototype hardware

  11. Conclusion • The goal is to prototype a tagging system that is: • Easy to deploy • Built around an open standard • Can be scanned with existing hardware (i.e. camera phones) • Cheap
