Ubiquitous home

  1. 1. Ubiquitous HomeBy Swati A. Sonawane M.E. (SSA)
  2. 2. INDEXIntroduction Challenges Architecture Appliances Example Conclusion
  3. 3. Introduction • Ubiquitous Home so called “Smart Home”Introduction • Definition • Smart Home : “A dwelling incorporating aChallenges communications network that connects the key electrical appliances andArchitecture services, and allows them to be remotely controlled, monitored or accessed”Appliances / Services • We can define a Ubiquitous Home as a Smart Home without intervention Example of Human being, taking its own decision depending upon context.Conclusions • Computation is invisible/calm
  4. 4. Need of Ubiquitous HomeIntroduction • Change in LifeStyleChallenges • Security • Health • Home EntertainmentArchitecture • To Managing large Information and Communication • To Maintain home easilyAppliances / • To Automate home appliance, Services – And also give full and remote control over them. • To create very pleasant and cherish ambience ExampleConclusions
  5. 5. Motivation • Outstanding Technological InnovationsIntroduction – Very Small Size of Embedded devices, almost make them invisible. – Improved Computational Power – Available in Low CostChallenges – Wearable Computing Devices – RFID, Sensors, Smart Card, Information Artifacts, and Tiny Smart DeviceArchitecture • Wireless Communication between devices – Bluetooth – Wi-FIAppliances / – ZigBee Services • Advances In Machine Learning – Algorithms Learn human behavior Example • Context Awareness and Adaptation – Autonomous Sensing, Environment Adaptation, Cooperation – Real-time and ProactiveConclusions – Adapting to Device Type, Time, Location, Temperature, Weather, etc
  6. 6. ChallengesIntroductionChallenges • Ease of Use • Impromptu interoperabilityArchitecture • No Systems AdministratorAppliances / • Reliability Services • Inference In The Presence of Ambiguity • Task Dynamism ExampleConclusions
  7. 7. Ease of UseIntroduction • Negligible or No Explicit Human inputChallenges • Capturing and Learning Human behaviorArchitecture • Ability to over-ride users input over sensed dataAppliances / • To give user of various choices of interfaces to communicate with system Services – Gesture Recognition – Voice Recognition (very important) Example • Take user’s advice and remember the decision on Critical tasks.Conclusions
  8. 8. Impromptu interoperabilityIntroduction • Unplanned interoperability DevicesChallenges – Currently devices (specially home appliances e.g. washing machine , refrigerator etc.) are not designed for to be controlled by centralized system – Lack of interfaceArchitecture • Detecting various devices and services in present rangeAppliances / Services • Communications between devices Example • Defining standards for such devices and servicesConclusions
  9. 9. No Systems AdministratorIntroductionChallenges • Self recovering to failuresArchitecture • Auto contacting with service center to get servicesAppliances / • Auto updating of software. Services • Instant Notifications for hardware failures Example – e.g. Not working smoke sensorsConclusions
  10. 10. Reliability • Ideally a Ubiquitous Home system should not crash.Introduction • As system controls multiple systems , failure of one service or device should not affectChallenges the working of other devicesArchitecture • It should prevent it self from false inputs – By taking multiple sensor data – Or user advice before taking critical decisionsAppliances / Services • It should be secured. – From network hacks / attacks ExampleConclusions
  11. 11. Inference in the Presence of Ambiguity • Much of Ubiquitous research holds that context awareness is crucial to the smart homeIntroduction • How smart does the smart home have to be ? • How much inference is required for these environments to be successful? Challenges • What benefits can be achieved with limited inference, or with no inference at all? • What is the cost of incorrect inferences?Architecture • are the sensors just sensing sensors? • trying to apply digital decisions to an analog worldAppliances / • user must be able to predict and understand behaviors of their technology: Services – systems expected behavior given a particular condition is – Known – systems facilities for detecting conditions is known Example – provisions for overriding systems decisions – ambiguity should not be hidden from the user • challenges the differentiation of what functions of theConclusions • smart home are possible with limited implication to user.
  12. 12. Task DynamismIntroduction • Application need to adapt to the user’s environment and uncertaintiesChallenges • Program need to adopt to changing goals.ArchitectureAppliances / Services ExampleConclusions
  13. 13. ArchitectureIntroduction Social Network , Web services IMChallengesArchitecture Centralized ControllingAppliances / System Services ExampleConclusions
  14. 14. Elements of Ubiquitous HomeIntroduction • Internal network – wired, wirelessChallenges • Intelligent control – gateway to manage the systemsArchitecture • Home automation – products within the homesAppliances / and links to services and Services systems outside the home Example • And Various SensorsConclusions
  15. 15. Appliances and servicesIntroduction • EnvironmentalChallenges • Security • Home entertainmentArchitecture • Domestic appliances • Information and communicationAppliances / • Health Services ExampleConclusions
  16. 16. Environmental (1) • Heating, ventilation and air conditioning programmable for daily activitiesIntroduction – Also with remote control via phone/InternetChallenges • Water temperature control on taps, baths and sinksArchitecture • Water quantity delivery controlled and monitoredAppliances / • Hands-free taps Services • Water leak monitoring ExampleConclusions
  17. 17. Environmental (2) • Lights programmable for daily routines, special settings forIntroduction watching TV and other activitiesChallenges • Lights come on to guide residents to bathroom or kitchen if they get out of bed at nightArchitecture • Voice controlled lightingAppliances / • Automatic curtain/window closing depending on light/weather conditions Services • Preset scene to user’s preference choose from: Home theatre Example scene, romantic scene, party scene, etc.Conclusions
  18. 18. Environmental (3) • Automatic gas, electricity and water metering, no more estimated billsIntroduction • Information available on a daily basis, not only for every monthChallenges • Online utility account management via PC (Internet) or TV (interactive service)Architecture • Energy use and running cost of each appliance available to help you use them economicallyAppliances / Services ExampleConclusions
  19. 19. Security • Alarms and Access controlIntroduction – Alerts delivered to householder via phone or Internet, automatic calling of security services – A security system connected with surveillance camera & alarms will be activated if there is any intrusion, with priority email alert sent automatically.Challenges – Window breakage alarms – Entrance by dedicated swipe cards, face and/or fingerArchitecture print recognition – Whole house deadlock when last person leavesAppliances / Services • Motion detectors Example • Environmental detectors – Fire/smoke detectors linked to fire service – Gas detectors to detect gas leaksConclusions – Carbon monoxide detectors to close down dangerous appliances
  20. 20. Home Appliances • KitchenIntroduction – Online recipe suggestions – Smart refrigerator – checks stock, orders automatically using Internet connectionChallenges – Oven programmable to cook when you’re out – Automatic breakfast – coffee, kettle & toasterArchitecture • CleaningAppliances / – Robot vacuum cleaner to clean when you’re out or asleep Services (By Samsung available in market) – Washing machine detects stray items Example i.e. red socks in white load and prevents washConclusions
  21. 21. Home Appliances • Smart WardrobeIntroduction – Suggest clothes depending on Weather or HeathChallenges • Smart Dressing Table – Having Multiple CameraArchitecture – Large Screen easy to Make-upAppliances / • Smart Mat – By sensing the body weight and footprint of the user, Services the smart mat immediately recognizes which user is stepping on the mat ExampleConclusions
