The Digital Desk
from Pierre Wellner in 1991
The DigitalDesk is built around an ordinary physical desk and
can be used as such, but it has extra capabilities. A video camera
is mounted above the desk, pointing down at the work surface.
This camera's output is fed through a system that can detect
where the user is pointing (using an LED-tipped pen) and it can
recognise the documents that are placed on it. The more
advanced version also has a computer-driven projector mounted
above the desk enabling electronic objects to be projected onto
real paper documents -- removing the burden of having to
switch attention between screen and paper and allowing
additional user-interaction techniques. [invented and built by
Pierre Wellner, Xerox EuroPARC]

What is design relevant knowledge?
• Perception Space
– The physical space where
the user’s attention is.
• Action Space
– The physical space where
the user acts in.
• Design Principle:
– perception space and action
space must coincide!

•
This remarkable ultra-lightweight
computer, worn as a belt, delivers
maximum information to users with a
minimum of work.
•
Designed for individuals who demand
mobility, this computer offers voice
control and heads up display for
complete, hands-free operation.
•
Users can enter or retrieve information
while going about their jobs, instead of
constantly returning to the shop area to
check a stationary computer, or stopping
work to punch keys.

More information and less
distraction
Information on the state of the road,
on the speed of the vehicle in front
(supplied by the intelligent cruise
control), on obstacles lying around the
next bend in the road identified by the
remote detection system, or direction
arrows sent by the driver guidance
system... drivers will be receiving
more and more information from
"intelligent" vehicle systems.
Natural User Interfaces (NUI)
1. design requirement
No technical equipment inside the
body space of the user!
2. design requirement
Perception space and
action space must coincide!
