Multiple-sensor interactive video laboratory systems for engineering and science education applications

The author discusses the need for and development of interactive video laboratory systems (IVLSs) linked with sensors for use in the science and engineering laboratory. The result is an interactive laboratory learning environment which can be used to enhance the learning and teaching of physical science, chemistry, physics, electrical engineering, and many other science and engineering disciplines. With an IVLS a student is presented with an on-screen introduction and tutorial to the experiment in full-color, full-motion video with hypertext and graphic overlays. The system will allow the student to perform experiments under computer control and collect data in real time from interfaced sensors or instruments. The experimental results can be plotted and analyzed with the help of the computer while the teacher provides instruction or help in the active `video window´ on the screen. This system eliminates simulation and guides the student through the actual experiment
