IndexIntroductionOverviewSensor ManagementDistributed Environment Action DatabaseNetworked Appliances CollaborationConclusion
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
