      • BREW
      • Power Consumption
    • Cellular Phone with Sensors
      • Sensor
      • Roles of Cellular Phone
  • Sensor
    • What it senses
      • Home Monitoring
      • Health Monitoring
      • Environment Monitoring
      • Habitat Monitoring
      • Earthquake Monitoring
      • Battlefield Monitoring
      •  Sensors exist everywhere
      •  Monitoring of physical world & its phenomena
    • Additional Features
      • Data Processing
      • Communication
      • within Low-Power Constraints
  • Cellular Phone
    • Main Function
      • Mobile Phone to connect people
    • Additional Features
      • Message Service
      • Camera and Camcorder
      • Multimedia Playback
      • with powerful computing and infrastructure-based network
      • Battery-operated
    • Roles for Sensors
      • A bunch of sensor nodes
      • A central node or a proxy server for sensor network
      • A terminal to human for sensing data
  • A. Cell Phone as a Sensor
    • To collect, to process, and to distribute data around people
    • Home Care
      • scan environmental data and forward it to care center
      • e.g.) check the gas leakage or poisonous material
    • Health Care
      • sense user’s health status and update/keep it.
      • e.g.) keep the heart rate or blood sugar rate for diabetics
    • Emergency Care
      • catch the emergent situation around people and scan/send data
      • e.g.) send rescue calls and captured data like picture
  • A-2. Health Care
    • People want to check their health simply
    • LG KP8400 : Diabetics Phone
      • Blood Sugar Testing Phone
        • place a strip of testing paper located near battery
        • place a drop of blood on the end of the strip
        • get a reading from the phone
        • upload to an online database for later retrieval
    •  Mobile Handset provides tools to check our health status and to keep or accumulate it
  • A-2. Health Care (cont’)
    • What else for heath care?
      • Very basic but important health care services
      • NONIN Onyx 9500 : Digital Finger Pulse Oximeter
        • Read data over fingertip
        • Real-time information on Heart-Rate and Blood Oxygen Saturation Level
    •  Simple devices for health care can be converged into mobile phones to check the health by user
  • A-3. Emergency Care
    • Cellular phone carries rescue button call for safe
    • Curitel PG-L5000 – SOS Phone
      • Emergency Button Call
        • Call at three saved numbers
        • Take two pictures and send them
        • Inform others of the position using GPS
    •  Mobile Handset senses emergent data
  • B. Cell Phone as a Proxy
    • To use computing power and communication ability of cell phones for sensor network like a Proxy or a central node
    • Offloading technology
      • CPU:1s MHz in Sensor VS 100s MHz in Cell Phone
      • e.g.) sensor captures images and cell phone encodes/encrypts them and transmits them.
    Sensor Network Cellular Network
  • C. Cell Phone as a Terminal
    • A terminal to human for sensing data
      • User can get information from sensor network immediately after requesting
    • An interface to human for information
      • User can collect preferred data through cellular phone
  • C–1. Security
    • Cellular phone scans user’s fingerprint
    • LG LP-3800 with Fingerprint Scanner
      • AuthenTech sensor for fingerprint recognition
      • Locked for unwanted user to use the phone
    •  Mobile Handset recognizes unique data for personal security
  • C-2. Code Interface
    • Colorzip.com : "ColorCode" - a n interface connect ing you to online contents
      • Media provides ColorCode
      • User camera on phone recognizes it
      • Server provides contents to client
      • User enjoys the contents
    •  Mobile Handset provides an interface like camera to read and process data
    1 2 3 4
  • Wrap-up
    • Cellular Network might be a huge-covering and very potential Sensor Network.
    • More Friendly and Closer to Human Being
    • Mobile Handset has an interface for sensing data and functionalities of computing and communication
