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.

IntroductionIn 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.

OverviewUbiquitous 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.

OverviewA Japanese-style room for remotely living

family members.Network Operating Center(NOC) between

the apartment and Japanese-style room.

Room Arrangement

Sensor ManagementEach room has cameras and microphones.

Floor Pressure sensorsFloor pressure sensors are installed

throughout the flooring.18cm x 18cm detection units Used to track residents Detect furniture positions

Sensor Management

Floor pressure sensor

Infrared SensorsInstalled at the top of the entrance doorAt the foot positions in the kitchen and in the

corridorDetect human movement

RFID systemsTwo Radio Frequency Identification(RFID)

systems are installed.Area-type RFID uses 315 MHzInstalled over the ceiling of each roomDetect the entrance of RFID tags into the

roomGate-type RFID uses 2.45 GHzEmbedded inside the wall around each room

entrance.

AccelerometersFour accelerometers are attached to back of

the bedroom floor in four cornersDetect human behavior to higher precision

DisplaysPlasma display panels and liquid

crystal displays (LCDs) and speakers are installed throughout the Ubiquitous home.

Provide residents with video and audio content

Sensor Arrangement

Distributed Environment Action Database (DEAD)Aim is to obtain information about the

behavior of residentsPatterns should be recognizedHistorical information is needed in order to

realize the services and provide them dynamically according to the situation

Distributed Environment Action Database (DEAD)DEAD stores and manages all the sensor

informationStructures information on people-to-people,

people-to-appliance and people-to-service interaction obtained from sensors and other devices.

Architecture of DEAD system

IssuesHome appliances and their functions are

designed independently by their manufacturers

Difficult to communicate with products of other manufacturers

Networked Appliances CollaborationUKARI-Core, a novel communication

middleware for networked home appliancesIt 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

Virtual Appliance connecting FEs

Networked Appliances CollaborationFunctional 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 typeA network appliance may have a single or

multiple FEs

Networked Appliances CollaborationFunctional Elements(FEs) communicate with

the help of middlewareA 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

ConclusionThe 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
