Pervasive Pervasive computingcomputing

Advances in technology allow us to embed computing power into smaller and smaller devices. Ubiquitous computing explores the new possibilities afforded by the fusion of computers with everyday objects. This talk will take a brief look at the foundations of pervasive computing, and lots more….

Computers EverywherePervasive Computing

What is Pervasive Computing? Technology View Computers everywhere – embedded into

fridges, washing machines, door locks, cars, furniture, people.

intelligent environment Mobile portable computing devices Wireless communication – seamless

mobile/fixed

User View Invisible – implicit interaction with your

environment Augmenting human abilities in context of tasks

Ubiquitous = mobile computing + intelligentenvironment

DefinitionsPost-desktop model of human-computer

interaction in which information processing has been thoroughly integrated into everyday objects and activities.

Ubiquitous computing, or calm technology, is a paradigm shift where technology becomes

virtually invisible in our lives.

All models of ubiquitous computing share a vision of small, inexpensive, robust networked processing devices, distributed at all scales throughout everyday life.

Fictional Technologies in SPY KIDS

Intelligent EnvironmentLights, air conditioning, TV automatically switch on

and off when you enter or leave rooms.

Sit on your favourite chair and TV switches on to the program you usually watch at this time of the day.

Use communicator/pda for phone, remote control, keys payments, passport, health records, authenticator.

Route input from ‘virtual’ keyboard to nearest suitable display.

Automatic detection of new items to control and physical

layout in a room or office, using computer vision.

Mobile Computing Vision

Universal connectivity – anywhere, anytime

Accommodate heterogeneity of networks and communicators

Ubiquitous intelligent environment – embedded computers everywhere

Easy user interaction Context independent access to services +

context dependent informationImagine Having a SINGLE remote to control

all your Electronic Gadgets.

Sentilla HardwareSentilla Mini core of pervasive

computing solution.Combining MSP430 microcontroller

with a TI/Chipcon CC2420 low-power wireless radio.

Design flexible and scalable.Mini pre-bundled with Sentilla Point

(the world’s only Java-compliant software platform for pervasive computers.)

Genre of product solutions

Energy management.Safety and security.Logistics and asset

management.

Sentilla Labs

Bite-sized versions of large-scale industry applications. Project refrigerator monitor.

Developer applications and prototype hardware.Project Motion DetectorUses a Radio Shack infrared detector to alert you when there's movement.

Fun applications. Project classic, Pong.

Challenge: Social IssuesControl: who watches the watchers, what

is being recorded, who has access and when

Security of informationPrivacy concernsTransparency of computer actions (or

lack thereof)Legal implications of enabling

technology

Make computers security “conscious”, minimise user intervention

Establish strong identity Goal: Cryptographically strong identity to

devices (endpoints) Means: Host Identity Protocol (HIP)

Assign and manage trust and authority Goal: Decentralised means for managing

authorisation Means: SPKI certificates

Public keys

Trust in pervasive computing environments
