A framework for speech-oriented CAD and BIM systems

Abstract

This article discusses the development of a Speech Oriented Graphics Interface embedded in CAD and BIM software. The aim is to provide the means to work with complex 3D BIM models with minimal touch operations. We can cite the growing need for tools and user interfaces to assist designers in handling complex models, minimizing the risk of producing changes accidentally. In this area, the integration of a graphical database in BIM applications can be seen as an advantage over traditional CAD applications. However, we can note a difficulty in this integration, due to the need to maintain the constant levels of mental concentration required in order to effectively manage a larger inter-connected graphical database. Specifically in this area, voice interfaces can help by avoiding the need of “touch” to work with the 3D models, looking for improving its robustness and consistency. In addition, SR is used in order to reduce cognitive stress among the users, trying eliminating the need to memorize and remember commands, names and locations in GUI interfaces.
