their familiar environment (at home or at work) on one
idea with constant support by Alan. The participants
started their idea from scratch and developed it over
the period. During these days, Alan’s assistance was
used constantly. Log files of the system showed that
the length of the ideas increased during the support. In
addition to this, monitoring the use of Alan by means
of the number of queries to Facebook, Twitter and
Tumblr, showed that the help of the AI was intensive
during all steps of idea generation. Furthermore, the
number of messages marked and attached to the ideas
(Ø=5 attached messages from Alan to an idea) showed
that the user makes use of Alan’s input. The idea
generation stage was therefore highly influenced by
Alan and can be seen as a collective work between the
user and the AI-like system
