1 Touch'n Locate demonstration
#toc("" "" "")
1.1 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>http://team.touchkey.fr/] code.
1.1. User documentation
After touching a tag, the user can :
* View the location on Google Map
{image:map.png}
* Reverse geocode the GPS coordinates to transform in a readable address
{image:reverse.png}
* Search for points of interest near the embedded location
By entering key words...
{image:poi1.png}
... then selecting a result ...
{image:poi2.png}
... and finally by reading the point of interest details :
{image:poi3.png}
* View the tag data
{image:tag_info.png}
1.1 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
Altitude and bearing fields are optional.
1.1 Dependencies
* [Team TouchKey>http://team.touchkey.fr/] code for Google Map interactions
* [JSON for JavaME>https://meapplicationdevelopers.dev.java.net/source/browse/meapplicationdevelopers/demobox/mobileajax/lib/json/] for JSON results parsing.
1.1 Tips for future improvements
* Cache maps in memory, to bring them back faster
* Improve the points of interest search area
