Augmenting, Looking, Pointing and Reaching Gestures to Enhance the Searching and Browsing of Physical Objects

David Merrill (MIT Media Laboratory, US); Pattie Maes (MIT Media Laboratory, US)

• Create natural, wearable devices to augment a certain experience.
  • Ring
  • Headset
• Used in shopping scenario
  • Find objects with certain properties
  • Find objects without certain properties (allergens, i.e.)
• Ring gave best results
• Audience questions/comments
  • Joe McCarthy: what about privacy? You don't want everyone to know you're allergic to peanuts, maybe?
  • personalized feedback (special, personalized symbols, ie)
• How do you specify your search?
  • For experiment, search was given
  • In real life, a kiosk at the store would set up your device.

Reach out and touch: using NFC and 2D barcodes for service discovery and interaction with mobile devices

Eamonn O'Neill (University of Bath, UK); Peter Thompson (Vodafone Group R&D, UK); Stavros Garzonis (University of Bath, UK); Andrew Warr (University of Bath, UK)

• Comparison of near-field communication (RFID) and 2D barcodes+camera as service identifiers/accessors/interactors.
• Comparison between trained and untrained users
• metric: time to read tags on various posters
• Confirmed hypothesis:
  • 2D Barcodes easier for untrained cases
  • NFC faster for trained cases
• Audience comment: these techs must be really easy to enable and configure on the phone
