Introduction• Ubiquitous Home so called “Smart Home”
• Definition
• Smart Home : “A dwelling incorporating a
communications network that connects
the key electrical appliances and
services, and allows them to be
remotely controlled, monitored
or accessed”
• We can define a Ubiquitous Home
as a Smart Home without intervention
of Human being, taking its own
decision depending upon context.
• Computation is invisible/calm
Introduction
Need of Ubiquitous Home
• Change in LifeStyle
• Security
• Health
• Home Entertainment
• To Managing large Information and Communication
• To Maintain home easily
• To Automate home appliance,
– And also give full and remote control over them.
• To create very pleasant and cherish ambience

Conclusions
Motivation• Outstanding Technological Innovations
– Very Small Size of Embedded devices, almost make them invisible.
– Improved Computational Power
– Available in Low Cost
– Wearable Computing Devices
– RFID, Sensors, Smart Card, Information Artifacts, and Tiny Smart Device
• Wireless Communication between devices
– Bluetooth
– Wi-FI
– ZigBee
• Advances In Machine Learning– Algorithms Learn human behavior
• Context Awareness and Adaptation– Autonomous Sensing, Environment Adaptation, Cooperation
– Real-time and Proactive
– Adapting to Device Type, Time, Location, Temperature, Weather, etc

Example
Conclusions
Ease of Use
• Negligible or No Explicit Human input
• Capturing and Learning Human behavior
• Ability to over-ride users input over sensed data
• To give user of various choices of interfaces to communicate with system
– Gesture Recognition
– Voice Recognition (very important)
• Take user’s advice and remember the decision on Critical tasks.

Conclusions
Impromptu interoperability
• Unplanned interoperability Devices
– Currently devices (specially home appliances e.g. washing machine , refrigerator etc.)
are not designed for to be controlled by centralized system
– Lack of interface
• Detecting various devices and services in present range
• Communications between devices
• Defining standards for such devices and services
Introduction
Challenges

Example
Conclusions
No Systems Administrator
• Self recovering to failures
• Auto contacting with service center to get services
• Auto updating of software.
• Instant Notifications for hardware failures
– e.g. Not working smoke sensors

Conclusions
Reliability• Ideally a Ubiquitous Home system should not crash.
• As system controls multiple systems , failure of one service or device should not affect
the working of other devices
• It should prevent it self from false inputs
– By taking multiple sensor data
– Or user advice before taking critical decisions
• It should be secured.
– From network hacks / attacks

Conclusions
Inference in the Presence of Ambiguity• Much of Ubiquitous research holds that context awareness is crucial to the smart home
• How smart does the smart home have to be ?
• How much inference is required for these environments to be successful?
• What benefits can be achieved with limited inference, or with no inference at all?
• What is the cost of incorrect inferences?
• are the sensors just sensing sensors?
• trying to apply digital decisions to an analog world
• user must be able to predict and understand behaviors of their technology:
– system's expected behavior given a particular condition is
– Known
– system's facilities for detecting conditions is known
– provisions for overriding system's decisions
– ambiguity should not be hidden from the user
• challenges the differentiation of what functions of the
• smart home are possible with limited implication to user.

Task Dynamism
• Application need to adapt to the user’s environment and uncertainties
• Program need to adopt to changing goals.
