2 o Ubiquitous What is "Ubiquitous"? Being everywhere at the same time; present everywhere (Idiomatic and Syntactic English Dictionary) Seeming to be everywhere (Longman Dictionary of Contemporary English) o Ubiquitous Computing Computing at any time, anywhere, by anyone Anyone can get access to information anywhere and anytime they want it 2

3 Computers Getting Smaller... 3

4 Computers in Everything... 4

5 And... Computers Everywhere, in Every Place 5

6 Essence of Ubiquitous Computing o Computers automatically identify objects Recognize real-world contexts What is this? Who is in this room? Does this person have a visual impairment? Where is this machine located? Is it raining now? Who does this person often talk to? 6

7 Support People in Many Situations o Computers that recognize real-world contexts... o... together support people Intelligent Lighting Intelligent Air Supply Intelligent Ceiling Intelligent Sensor Intelligent Wall Intelligent Chair Communication Machine Intelligent Desk Full Automatic Movable equipment OPEN ENDED Intelligent Floor Ubiquitous Computing: Computers everywhere to support people's lives 7

8 Features of Ubiquitous ID Technology Feature 1: Well-Designed Network-Based Architecture o A tag contains an identifier (ucode), and a network provides information services. o The ubiquitous ID architecture is compatible with the Internet and mobile phone networks. 8

9 Ubiquitous ID Architecture (Getting Information from Objects) ucode, context server addresses ucode, context ucode Resolution Servers Product ucode Ubiquitous Communicator service information Information Servers 9

19 Feature 2: Ubiquitous Communicators (UC) o Mobile devices/user interfaces for ucode tags Multi-protocol communication interfaces WiFi, Bluetooth, IrDA, cellular phones,... Multi-protocol RFID R/W 2.45 GHz, MHz,... Rich multimedia functions JPEG, MPEG4, MP3,... High Security IC card inside, Biometrics,... 19

21 Objectives and Goals of the Self- Controlled Travel Support Project o Ministry of Land, Infrastructure and Transport, Government of Japan o Applies the concept of "soft" infrastructures using IT (ubiquitous computing technologies) to the field of national transport Universal design of the national land o Aims to build universal information infrastructures for a wide variety of people Not just for people with disabilities, aged people, or foreign people Many applications Sightseeing support, ITS, public properties management, emergency information, robot navigation, traceability logs, security, place-dependent transactions and public services,... 21

22 Attaching Information to Places Real World ucode ucode Definition Space Contents Service Space 22

23 What is Ubiquitous Spatial/Place Information Systems? o o o o By developing "place" information systems on the basis of ubiquitous computing technologies,... Universal/multi-purpose national-land information infrastructures As one application, self-controlled travel support Not a closed system, aiming for extensions in various directions and connections with other systems 23

24 Location-Aware Information Services o We are installing a large number of active tags, sensor networks, and RFIDs across Japan o Support pedestrian navigation, especially for people with disabilities and foreign people o Also support sightseeing, shopping, supply-chain management, and so on o A kind of ITS: Intelligent Transport System FOR HUMANS 24

25 Building Infrastructures for Location-Aware Information Services Sapporo, Hokkaido Aomori Nagoya Expo 2005, Aichi Kobe, Hyogo Tsuwano, Okayama Asakusa, Tokyo Ueno, Tokyo Shinjuku, Tokyo Ginza, Tokyo 25

28 Tokyo Ubiquitous Technology Project in Ginza ucode tag (store, infrared) ucode tag (sidewalk, wireless) ucode tag (store, IC tag) 28

29 Thousands of Ubiquitous ID Tags in the Ginza Area, Tokyo Ground-level Test Area Underground Test Area 29

30 Examples of Tags 30

31 Information Services in the Tokyo Ubiquitous Technology Project, Ginza 31

32 Purposes o Self-controlled travel support project in Ginza o Empirical testing in the real world, Tokyo To vitalize commercial areas, to build infrastructures for new information services Various contents services With industries o Universal design Support for people with disabilities Tour guide for foreigners o Realization of a secure society Disaster prevention Safe cities for everyone o Disseminate advanced technologies from Japan 32

33 Empirical Testing 1. To know where you are, and obtain information about the place - Not just latitude/longitude - With good accuracies in the cities (GPS not usable) 2. Route navigation to a destination, and information about the destination - Context-aware navigation - Universal design (for people with disabilities, aged people, foreigners) 3. Emergencies 33

34 Contents Provided o Types of Information Current position, location, place information Government information Emergency information Transfer information, train operation information Bathrooms for people with disabilities, barrier-free routes Shops and goods information Sightseeing/tour information o Providing optimal information depending on the context Multiple languages (Japanese, English, Chinese, Korean, etc.) Speech for people with visual impairments, sign language and vibration for people with hearing impairments Age and gender Weather, seasons, emergencies 34

35 Browsing Functions Coupled with ucodes o Retrieve information through the network for accessed ucodes o Data formats Web pages in HTML Maps in SVG Images/pictures in JPEG Animations/movies in MPEG Interactive contents in Ajax Access Point Network ucode Relation Database ucode Information Server 35

36 Examples of Contents 多国語 地下鉄へのルート案内 最寄の身障者トイレやバリアフリールート案内 36

37 Examples of Contents 店舗への案内 37

38 Pedestrian Navigation o Navigation with maps and speech o Flexible navigation suitable for specific situations Nearest bathroom Go underground when it rains Pedestrian zones on Sundays Navigation ナビゲーション Destination: Wako Turn left. And turn left again at the end of the hall. 経路案内 歴史 周辺情報 38

39 3-D Panoramic Views o Realistic 3-D representations o Links to maps, animations, and Web pages 3Dパノラマ 3-D Panorama パノラマ 歴史 周辺情報 Ginza Mitsukoshi 39
