CAAD research

Development of innovative design
systems

From explorative: How can we
improve design support?

To deductive: How well does the
system perform?

Idea Space System (ISS):

Digital graphics and annotations



Movie ISS

user session

ISS Findings

1.
Word graphs are actually applied

2.
Word graphs contribute to
overcoming periods of inactivity

3.
Architects are not equally
engaged in verbal design

Structural Sketcher (SS):

Designing with graphics units
and Relations between them


SS: Kite manipulator

SS Findings

1.
SS performs better than other
software, but worse than pen &
paper

2.
A significant reduction of user
actions compared to other
software

3.
Need for ‘doodling’

Decision Support:
Bayesian Networks (BN)

BN is a formalism for performing
reasoning using partial beliefs
under conditions of uncertainty

Case: Measuring housing
preferences

Retrospective and Prospective


DS = between CS


SS


Experimental results are often not
glamorous


Designers are incapable of
specifying their own needs
