3. INTRODUCTION
Solution is OXYGEN.
Machine centered.
We are serving
them.
project
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

way they communicate with
one another, using speech.

provides a number of limiteddomain interfaces.
The spoken language
subsystem is an sub part of
Oxygen's infrastructure.

•Speech recognition
• Language understanding
• Language generation
• Speech synthesis

Vision
#
Say "show it to me there"
turning their heads or pointing
with their arms to indicate
where.
U can give order by Using
facial expressions and gestures.
Computers recognize and
classify features and actions

They detect patterns and
object interactions
The visual processing system
contains
• visual perception
• visual rendering
Components
•Object recognition
• Activity monitoring

35. Conclusions
#
Project Oxygen is a project to build
a human centered, pervasive
computer.
It is a $50 mn project sponsored by
“oxygen alliance” which includes
•Acer Inc.,
•Delta Electronics Inc.,
•Hewlett-Packard Co.,
•Nippon Telegraph
•Nokia Corp. and
•Philips Research
Started in 1999, but not yet
completed.
Concept of N21 and INS are very
difficult to be practical.
