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

– 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

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.
