Agent based systems to implement natural interfaces for CAD applications

Currently, important advances are being carried out in CAD (Computer Aided Design) applications; however, these advances have not yet taken place for CAS (Computer Aided Sketching) applications. These applications are intended to replace complex menus with natural interfaces that support sketching for commands and drawing, but the recognition process is very complex and doesn't allow its application yet. So, although natural interfaces for CAD applications have not yet been solved, works based on sketching devices have been explored to some extent. In this work, the authors propose a solution for the problem of recognition of sketches using an agent-based architecture, which distributes the agents hierarchically to achieve the best decision possible and to avoid reliance on of the drawing sequence. © 2012, IGI Global.
