IntroductionIntroduction
Define a smart environment as Able to acquire and apply knowledge about the
environment Can adapt inhabitant's preferences and
requirements to improve their experience
The type of experience that The type of experience that individuals wishindividuals wish
Safety of inhabitants Reduction of cost of maintaining the inhabita
nts Resource optimization(energy or bandwidth) Task automation
The components of a smart The components of a smart environmentenvironment
Perception of the environment is a bottom-up process
Action execution flows top-down
Technologies Technologies

Pervasive or ubiquitous computing Where you want When you want What you want How you want
Major challenges in pervasive Major challenges in pervasive computingcomputing
Invisibility and Unawareness Service discovery Interoperability and Heterogeneity Mobility Privacy and security
Location-aware servicesLocation-aware services
Context (location and activity) awareness Current activity state of the user The characteristics of their environment
Mobility and activity creat an uncertainty of their state Minimize this uncertainty as captured by Shann
on’s entropy measure
Mobility / activity trackingMobility / activity tracking
Predict future mobility and actions Reduce the location uncertainty Minimizes the entropy Help device automation and efficient resource
management Single and multiple inhabitant
Natural interfaces for smart Natural interfaces for smart environmentsenvironments
Designers need to consider Usability of the interface End-user friendly The adaptiveness of the interface

Making sure the individual is safe and performing routine activities
Helping individual compensate for impairment
Determining physical or cognitive status
Conclusions and ongoing Conclusions and ongoing challengeschallenges
Multiple inhabitants in a single environment The fusion of different type environment Security and privacy
