Conclusion

Pervasive, Human Centered Computing

➢Pervasive Computing➢ Term coined by Mark Waiser

➢ Information processing is integrated into everyday objects & activities

➢Human Centered Computing ➢ Emerging, inter disciplinary field

➢ Concerned with computing and computational artifacts

as they relate to human condition

Overview of Project OxygenVision

● Computation embedded into human life, like the Oxygen we breathe

Approach● Combination of specific user & system technologies

● User technologies address human needs

● System technologies like software, networks make devices understand

humane way of interaction

Challenges● Pervasive yet Embedded

● Dynamic yet Eternal

Application

Device Technologies E21 Intelligent Spaces

● Space centered computation, embedded in ordinary environment

● Populated by cameras, microphones, displays, sound output

● Controls for physical entities like curtains, lighting, door-locks

● People interact in Intelligent Spaces naturally, using speech, gestures

H21 Mobile Devices● Person centered devices also the Universal Personal Appliances

● Equipped with perpetual transducers such as microphone, speakers

● Auto reconfigurable, light weight, inexpensive

● Anonymous generic devices

E21 Intelligent Spaces

Space centred computation, embedded in ordinary environment

Connected to sensors, suitably encapsulated into physical objects

Communicate with each other and nearby handheld devices (H21)

through Dynamically Configured Networks (N21)

E21 provide computational power throughout the system to

● Communicate with people

● Support Oxygen User Technologies

● Monitor and control their environment

E21 software is robust, and configurable among themselves

Oxygen TodayThe Intelligent Room

● Capable of detecting motion

● Recognize voice patterns

● Identify a person by face

sensors

H21 Mobile devices Generic devices also called Universal Personal Appliances

Do not carry large amount of permanent local state

They configure themselves according to the person using them

Being small and lightweight, they have few transducers

They have less computational power than E21

Can be configured to be used as radio, cellphone or even TV

Power efficient, the software controls the power consumption

Oxygen Today

The H21 Prototype

N21 Network Technologies

Networks make it easy to establish ad-hoc collaborating communities of

computer devices

Through algorithms, protocols and middleware, they

● Configure collaborative regions automatically

● Create topologies and adapt them to change

● Provide automatic resource and location discovery

● Provide secure, authenticated and private access

N21 networks use intentional names rather than conventional static names

They support location discovery through proximity

Software Technologies

Software systems adapt - to user, to environment, to change, to failure

Project Oxygen's software architecture provides mechanisms for● Building applications using distributed components

● Customizing, adapting and altering component behavior

● Person-centric rather than device-centric security

● Disconnected operation and nomadic code

Eternal Computation: The system must never shut down or reboot

though components are upgraded, removed and reinstalled

Perpetual Techniques

Two kinds of perpetual techniques

● Spoken Interaction● Users and machine engage in interactive conversations

● Highly efficient

● Visual Interaction● User interacts with perpetual modalities

● Use of body language and gestures

Spoken Interaction Speech recognition Language understanding Language generation Speech synthesis

Visual Interaction

It consists of

● Visual perception subsystem, and● It recognizes and classify objects and actions

● Complements spoken language subsystem

● Visual rendering subsystem● Creates 3D scenes from 2D data

● Provide macroscopic view of application supplied data

User Technologies

User Technologies include● Knowledge Access

● Access any time, anywhere, almost anything● Automation

● Automate control of physical environment

● Collaboration

● Connecting people

Knowledge Access

Personalized repository that keeps track of what we interests us

The search for “fat book on computers” will return person biased results

Automated observers● They always keep a track of the data you are looking for

● The data is modelled according to your personal profile

Oxygen Today

Distribution & Mobility The cricket location support system

Perceptual Interfaces Multimodal, multi-lingual softwares like “SpeechBuilder”

have been designed

Security & Privacy Decentralised scheme of oxygen

User never needs to revel their own location

Conclusion

➢ Bringing abundant computation and communication, as pervasive as

free air, naturally into people's life

➢ Mark Weiser's vision of ubiquitous, pervasive computing is gradually

becoming reality

➢ Commercial versions of H21 are ready to be launched

➢ The E21 and N21 will soon be spread everywhere, not just the labs
