Abstract
The Intuitive Interface is a research project that investigates new methods of interaction with the computer by freeing the computer from the non-flexible desktop setup and integrating the interface in the every-day physical environment of the user. We focus on creative people, as users, who are often unfamiliar with computers and hesitate before getting involved with mouse and keyboard, because of the symbolic and alphanumeric abstraction that is necessary. The system makes strong use of body movements to trigger commands and real space in front of a rear projection screen to store and retrieve information. This so called memory-function is based on a technique called "Ars Memoriae" which was used by orators in antiquity to memorize long speeches. The orator would create icons of the subjects to be memorized and place them at chosen locations in an imaginary architecture. The icons are used as links to the information and as the orator (in his mind) walks to the memorized locations he is able to retrieve the icons and with them the information. Our scenario uses this metaphor by allowing the user to put entities at chosen locations in real space and to retrieve these icons and the linked information at a later time. A stereo computer vision system is used for sensing user posture and simple gestures like pointing, together with a speech recognition software that is used to trigger commands. The vision system is based on color segmentation and blob analysis.
