TUCKER2015-09-292015-09-2919841017-4656https://doi.org/10.2312/eg.19841015During the last ten years a lot of work has been done in architectural applications using computers and especially computer graphics. It is however obvious that these new tools have not been fully accepted by architects in common. We think that one of the main reasons for this is the poor facilities for the interaction between the user and the machine. In our project at KTH in Stockholm we use modern workstations with bitmapped techniques to study the possibilities to design good interactive facilities. Ideas for interactive techniques are gathered together with architects and are implemented on a Xerox LISP machine. The most interesting and important techniques are studied in experiments that are set up together with behavioural scientists.10.2312/eg.19841015
