Natural User Interface Integrated In Petri Net Educating Environment

This contribution deals with an educating tool called PN Designer, developed to support Petri Nets education - design, simulation, properties analysis and testing. It helps students to master Petri Nets and can also be used to examine students’ knowledge. Teachers are able to prepare various tasks that can then be used in the learning and/or assessment process. To support the assessment process the server part was designed to provide test creation, distribution, and automated evaluation facilities. Although primarily devoted to Tablet PCs, with some loss of comfort the environment can be used on traditional computers as well. The results show a great deal of the attractiveness of this kind of learning, and substantial time saving in the assessment process while preserving the assessment quality.
