What is IoT?

• Internet of Things(IoT) can be described as
  connecting everyday objects like smart-phones,
  Internet TVs, sensors and actuators.
• They are linked together enabling new forms of
  communication between things and people and
  between things themselves.
• Various devices in the home like air conditioner,
  lightings, home security and entertainment
  systems are now being connected to the internet.

Introduction

• In this paper, the experimenters collect
  real-life data as if living in their own house,
  not in a laboratory.
• We will discuss an overview and detailed sensor
  arrangement of the Ubiquitous Home.

5
Overview

• Ubiquitous home was constructed in National
  Institute of Information and Communication
  Technology in Japan.
• It consists of a living room, dining-kitchen,
  study room, bed room, washroom and bathroom.

6
Overview

• A Japanese-style room for remotely living family
  members.
• Network Operating Center(NOC) between the
  apartment and Japanese-style room.

Room Arrangement
8
Sensor Management

• Each room has cameras and microphones.

9
Floor Pressure sensors

• Floor pressure sensors are installed throughout
  the flooring.
• 18cm x 18cm detection units
• Used to track residents
• Detect furniture positions

10
Sensor Management

• Floor pressure sensor

11
Infrared Sensors

• Installed at the top of the entrance door
• At the foot positions in the kitchen and in the
  corridor
• Detect human movement

12
RFID systems

• Two Radio Frequency Identification(RFID) systems
  are installed.
• Area-type RFID uses 315 MHz
• Installed over the ceiling of each room
• Detect the entrance of RFID tags into the room
• Gate-type RFID uses 2.45 GHz
• Embedded inside the wall around each room
  entrance.

13
Accelerometers

• Four accelerometers are attached to back of the
  bedroom floor in four corners
• Detect human behavior to higher precision

14
Displays

• Plasma display panels and liquid
  crystal displays (LCDs) and
  speakers are installed
  throughout the
  Ubiquitous home.
• Provide residents with video
  and audio content

16
Distributed Environment Action Database (DEAD)

• Aim is to obtain information about the behavior
  of residents
• Patterns should be recognized
• Historical information is needed in order to
  realize the services and provide them dynamically
  according to the situation

17
Distributed Environment Action Database (DEAD)

• DEAD stores and manages all the sensor
  information
• Structures information on people-to-people,
  people-to-appliance and people-to-service
  interaction obtained from sensors and other
  devices.

Issues

• Home appliances and their functions are designed
  independently by their manufacturers
• Difficult to communicate with products of other
  manufacturers

20
Networked Appliances Collaboration

• UKARI-Core, a novel communication middleware for
  networked home appliances
• It can discover and connect appropriate
  functional elements(FEs) from the networked
  appliances dynamically
• FEs are connected as a virtual appliance to
  provide service to the residents

21
Virtual Appliance connecting FEs
22
Networked Appliances Collaboration

• Functional Elements(FEs) are defined based on
• type of media
• information processing
• For example, AudioGenerate is a type of FE
• It creates audio-type information
• An FE of microphone belongs to this type
• A network appliance may have a single or multiple
  FEs

23
Networked Appliances Collaboration

• Functional Elements(FEs) communicate with the
  help of middleware
• A virtual monitoring system uses the FE of image
  capture from the digital still camera and the FE
  of image display from the television set
• The infrared sensor in the door can be used to
  start this service with the help of UKARI-Core

24
Conclusion

• The services offered by ubiquitous home not only
  helps the persons with disabilities and elderly
  people, but also helps the whole family
• It can be extended to various types of devices
  such as home robots
• Resource sharing and user accessibility of
  functional elements can be added in the future
  work
