Difference between Passive RFID and Active RFID
Tour guiding system
providing a variety of information rather than only navigating route for the user.

Key element: Are they only used for navigation services?
In the ubiquitous computing environment, many computers and sensors are distributed to the urban environment. It is easy to get information at everytime, everywhere based on the ubiquitous computing and sensor network.
Communication distance between the device and its system (Satellite System, network server and machine) strongly affects t he size of service area.
2D street navigation system in the
urban environment is no longer
enough information for location
Mobile phone-based location service
GPS is one of the most familiar devices in location based systems.
Pedestrian users who uses GPS positioning navigation service often feel some confusion near subway-exits surrounded by tall buildings.
walking, driving cars, train, buses and even transfer information for airlines and subways
Japan, China, and USA
Mobile phone-based location service What is Total Navigation service? How pedestrian can be navigated in crowed urban environment and the underground streets by total navigation system?
Example: JR (Japanese national railway) line in Tokyo area 5km http://www.anterras.net/candy/hitched/japan_trip/JREast_Tokyo.png
GPS and Cell tower
3D User interface
The GPS repeater system
When GPS is not available, the locations of nearby cell towers are used to produce a location estimate.
- The gpsOne solution combines GPS and cell-based data to achieve the most accurate positioning outside and inside buildings.
- Pedestrian can use 3D navigation system
RFID : Key element and common problem
RFID tag recognition system
RFID tag is especially used for a ticket gate. This RFID tag system is only available in short communication distance.
Is it only for a ticket gate?
There is a rechargeable contactless smart card. Suica stands for “Super Urban Intelligent Card”. The card incorporates contactless RFID technology.

The RFID chipped mobile phone is now used for other services.
Benefit of RFID chips
RFID card as an information tool
'SuiPo,' or Suica Poster, which uses a combination of IC card ticket ‘Suica’ and Internet accessible mobile phone. Customers can get e-mail information by touching their SUICA on the reader located near the poster.
Entertainment tool - Free of charge

Ubiquitous communicator : Key element
When the user arrive the place of an artwork, the device inform you the location and introduce the artwork and the artists by showing graphic images, a movie with audio and text description on the display.

Space-identifying ubiquitous infrastructure 1
Indoor: An infrared beacon is installed on a ceiling.
Outdoor: Active RFID tag is installed in a lamp post.
Active RFID tags have their own internal power source.
Sensors: Infrared beacon and Active RFID tag http://www.isotc211.org/WorkshopXian/Presentations/Noboru_Koshizuka_ Ucode .ppt Short range Need battery, Expensive, Not small Disadvantage Small, No battery Long range Advantage Passive RFID tag (SUICA) Active RFID tag (UC)

Route navigation and mapping .
Location services do not only support positioning navigation for pedestrians, but also a small devices and its system provides a innovative service as an entertainment tool.
The user wants to get multiple information which relates to their interests or their real time situation.
