The UniTrain-I system is a computer-based training and experimentation system for vocational and furthertraining and education in the areas of basic and advanced electrical engineering and electronics. Its multimediacourses combine cognitive and hands-on (haptic) training units into a comprehensive unified concept,specifically enabling students to acquire skills in the handling of equipment. Starting with basic courses and
advancing to cover a huge variety of electrical engineering and electronics topics, a wide range of multimediacourses is available for study in school or in professional and advanced training courses. The UniTrain-I systemis completely self-contained and can be used anywhere at any time. The multimedia learning environment thesystem provides high degrees of motivation, and maximum learning effectiveness in laboratories, at work or athome. It thus becomes a guarantor for effective and efficient study. Access to the multimedia courses andcontrol of virtual instruments and experiment hardware is provided by LabSoft, the system's open experimentplatform. The courses teach the theoretical building blocks and provide experiments to be carried out using thecourse-specific experiment hardware. The intelligent measurement interface supplies the analog and digitalmeasuring and control I/O and represents, in combination with the system's virtual instruments, a high qualityitem of laboratory equipment. In addition, students' progress can be monitored and electronically documented onthe basis of fault finding experiments with faults simulated by the hardware as well as tests of knowledge. Theelectrical and electronic circuits needed for the experiments are connected to the system with the aid of anExperimenter module.
