Pervasive, Human Centered Computing Overview of Project Oxygen Device technologies Network technologies Software technologies Perpetual technologies User technologies Oxygen Today Conclusion

Pervasive, Human Centered Pervasive, Human Centered ComputingComputing

Pervasive Computing Information processing integrated into everyday objects & activities. free as air naturally into people's lives.

Human-centered Emerging, inter-disciplinary field Concerned with computing and computational artifacts as they relate to human condition

VisionVision

In the future, computation will be human-centered.

It will be freely available everywhere, like batteries and power sockets, or oxygen in the air we breathe.

It will enter the human world, handling our goals and needs and helping us to do more while doing less.

VisionVision configurable generic devices, either handheld or

embedded, will bring computation to us, irrespective of our location.

No need to type, click, or learn new computer jargon.

communicate naturally, using speech and gestures that describe our intent

ChallengesChallengesTo support highly dynamic and varied human activities, the Oxygen system must master many technical challenges. It must be-

pervasive—it must be everywhere, with every portal reaching into the same information base; embedded—it must live in our world, sensing and affecting it; nomadic—it must allow users and computations to move around freely, according to their needs; adaptable—it must provide flexibility and spontaneity, in response to changes in user requirements and operating conditions;

ChallengesChallenges

powerful, yet efficient—it must free itself from constraints imposed by bounded hardware resources, addressing instead system constraints imposed by user demands and available power or communication bandwidth;

intentional—it must enable people to name services and software objects by intent, for example, "the nearest printer," as opposed to by address;

eternal—it must never shut down or reboot; components may come and go in response to demand, errors, and upgrades, but Oxygen as a whole must be available all the time

ApproachApproach

Combination of specific user & system technologies

User technologies address human needs. Speech and vision technologies enable us to

communicate with Oxygen as if we're interacting with another person, saving much time and effort.

System technologies like software, networks make devices understand human way of interaction

ConclusionConclusion

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
