Project Oxygen aims to make computation as freely available as oxygen in the air. It envisions a future where generic handheld and embedded devices called H21 and E21 are connected through a wireless network N21. These devices would allow natural communication using speech and gestures without needing to type or learn computer interfaces. The technologies developed under Project Oxygen include device technologies for the H21 and E21, network technologies for the N21, software technologies, and perceptual technologies for speech and vision. Challenges include making the system pervasive, embedded, nomadic, adaptable, powerful yet efficient, intentional and eternal. While started in 1999, Project Oxygen remains a vision that has not yet been fully realized due to the difficulties in

OXYGEN
Right now, Computers
have required us to
interact with them on
their own terms
Difficult to use.

4. What Is OXYGEN
Bringing abundant computation
and communication, as
pervasive and free as
air, naturally into people's lives.

Computation will be
• human-centered.
• freely available
everywhere, like batteries
and power sockets, or
oxygen in the air we
breathe.



5. What Is OXYGEN
configurable generic
devices, either handheld or
embedded, will bring
computation to us, irrespective
of our location.

We won't have to type, click, or
learn new computer jargon.

Instead, we'll communicate
naturally, using speech and
gestures that describe our
intent
