Short description

This demonstration presents the usage of NFC phones and RFID tags to present locations and associated points of interest to the user.

This demonstration is based on the Team TouchKey code.

1.1. User documentation

After touching a tag, the user can :

• View the location on Google Map

• Reverse geocode the GPS coordinates to transform in a readable address

• Search for points of interest near the embedded location

… then selecting a result ...

… and finally by reading the point of interest details :

• View the tag data

Technical documentation

Locations can be stored in two different ways :

• in a Locate record type : urn:nfc:wkt:L
  • fields are stored in their binary representation
  • fields order : latitude, longitude, altitude, bearing
  • This record type is smallest possible one
• in a URI record type : urn:nfc:wkt:U
  • URI format : http://loc/latitude/longitude/altitude/bearing
  • This record type can be written directly by most NFC devices

Dependencies

• Team TouchKey code for Google Map interactions
• JSON for JavaME for JSON results parsing.

Tips for future improvements

• Cache maps in memory, to bring them back faster
• Improve the points of interest search area
