Ubi Presentation

  1. 1. Ubiquitous Technology for Location Based Systems and Services
  2. 2. Introduction 1 <ul><li>Mobile Phone Based Location Service </li></ul><ul><li>Street navigation and wayfinding research </li></ul><ul><li>The IEEE Computer Society 2007 </li></ul>1. NAVITIME: Supporting Pedestrian Navigation in the Real World 2. Implementation of Interactive Poster “Suipo’ <ul><li>Radio Frequency Identification (RFID) </li></ul><ul><li>SUICA (Rechargeable contactless smart card) </li></ul><ul><li>The service provides the limited location-based service on RFID tag recognition system . </li></ul><ul><li>Computer Human Interaction (CHI) 2007 </li></ul>Three Academic papers
  3. 3. Introduction 2 <ul><li>Introducing the latest ubiquitous device which is called U biquitous Communicator (UC). </li></ul><ul><li>Difference between Passive RFID and Active RFID </li></ul><ul><ul><li>Route navigation </li></ul></ul><ul><ul><li>Tour guiding system </li></ul></ul><ul><ul><ul><ul><li>providing a variety of information rather than only navigating route for the user. </li></ul></ul></ul></ul><ul><li>ACM 2008 </li></ul>3. A Space-Identifying Ubiquitous Infrastructure and its Application for Tour-Guiding Service Three Academic papers
  4. 4. Key element: Are they only used for navigation services? <ul><li>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. </li></ul><ul><li>Communication distance between the device and its system (Satellite System, network server and machine) strongly affects t he size of service area. </li></ul>Key element:
  5. 5. Common problem <ul><li>2D street navigation system in the </li></ul><ul><li>urban environment is no longer </li></ul><ul><li>enough information for location </li></ul><ul><li>based services!! </li></ul>
  6. 6. Mobile phone-based location service <ul><li>GPS is one of the most familiar devices in location based systems. </li></ul>Navitime <ul><li>Pedestrian users who uses GPS positioning navigation service often feel some confusion near subway-exits surrounded by tall buildings. </li></ul><ul><li>Destination via: </li></ul><ul><ul><li>walking, driving cars, train, buses and even transfer information for airlines and subways </li></ul></ul><ul><li>Available in: </li></ul><ul><ul><li>Japan, China, and USA </li></ul></ul>
  7. 7. 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?
  8. 8. Example: JR (Japanese national railway) line in Tokyo area 5km http://www.anterras.net/candy/hitched/japan_trip/JREast_Tokyo.png
  9. 9. GPS and Cell tower <ul><li>3D User interface </li></ul>The GPS repeater system <ul><li>When GPS is not available, the locations of nearby cell towers are used to produce a location estimate. </li></ul><ul><li>- The gpsOne solution combines GPS and cell-based data to achieve the most accurate positioning outside and inside buildings. </li></ul><ul><li>- Pedestrian can use 3D navigation system </li></ul>
  10. 10. RFID : Key element and common problem <ul><li>RFID tag recognition system </li></ul><ul><ul><li>RFID tag is especially used for a ticket gate. This RFID tag system is only available in short communication distance. </li></ul></ul>Is it only for a ticket gate? <ul><li>There is a rechargeable contactless smart card. Suica stands for “Super Urban Intelligent Card”. The card incorporates contactless RFID technology. </li></ul>
  11. 11. RFID chipped mobile phones 1 <ul><li>RFID chipped mobile phones </li></ul><ul><ul><li>The RFID chipped mobile phone is now used for other services. </li></ul></ul>Benefit of RFID chips
  12. 12. RFID card as an information tool <ul><li>'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. </li></ul>Entertainment tool - Free of charge
  13. 13. Ubiquitous communicator : Tokyo midtown ubiquitous art tour <ul><li>Tokyo Midtown is the latest commercial complex in Tokyo, Japan. </li></ul><ul><li>There are 20 artworks within the area. </li></ul>3D Map of Tokyomidtown http://www.masslogue.com/archives/2005/08/05_0130.html
  14. 14. Ubiquitous Art Tour <ul><li>Menu: 7 Courses </li></ul><ul><ul><li>120min Course , 30min Course , Art Special Course, Architecture Design Course , Garden Course , Large Sculptures Course , Rainy Day Course </li></ul></ul>Tour map
  15. 15. Ubiquitous communicator : Key element <ul><li>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. </li></ul>Touch panel display
  16. 16. Space-identifying ubiquitous infrastructure 1 <ul><li>Indoor: An infrared beacon is installed on a ceiling. </li></ul><ul><li>Outdoor: Active RFID tag is installed in a lamp post. </li></ul><ul><ul><ul><li>Active RFID tags have their own internal power source. </li></ul></ul></ul>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)

  18. 18. Conclusion <ul><li>Route navigation and mapping . </li></ul><ul><li>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. </li></ul><ul><li>The user wants to get multiple information which relates to their interests or their real time situation. </li></ul>Location based communication services
