An Agent-Based Multimodal Interface for Sketch Interpretation

We present a multimodal interface for sketch interpretation that relies on a multi-agent architecture. The design of the interpretation engine and the different agents are based on a user-centered approach where efficiency measure is defined as user satisfaction. So far, several graphical agents have been implemented for recognizing basic graphical objects (e.g. lines, circles, etc.) as well as more complex (e.g., hatches, stairs, captions, etc) in architectural design. Besides, vocal agents have been developed for recognizing spoken annotations (e.g. dimensions) and interface commands. Realistic evaluations with professional users have demonstrated the potential interest of the proposed system

Premières évaluations d'un bureau virtuel pour un processus de conception augmenté

Many CAD tools already allow to create and manipulate directly ideas in a digital way. However, designers still use the pen and paper technique during the early design phase of their projects. Indeed, existing CAD tools constraint the creative work. There is a need for a spontaneous human computer interaction in design computing. In order to answer to this need, we develop an integrated aided design tool based on an Virtual Desktop. The designer sits in front of a classical desktop where s/he can create and manipulate drawings and generated models. The paper relates the observations made from an experiment about the use of the Virtual Desktop by a designer. That experiment demonstrates that the immersive aspect of our system interface modifies the relation existing between the designer and his/her model and, this way, its generates a new type of augmented interaction.
