A Multimedia Visual Feedback in the Web-controlled Laboratory

The paper presents development work related to create WWW based remote control laboratory for teaching Applied Photonics. In order to minimize the cost at the enduser domain, simple WWW browser with fundamental plug-in (Java applets, HTML Pages and LabWindows applets) to support the remote control and video transmission functionality of the remote control is proposed. As for telepresence and monitoring of device actions, a simple type zooming web-camera is connected to the hosting multimedia PC via the USB port. The web-camera assists in visual feedback of the system and presents the feeling of telepresence for the end-user (student). USB web-cameras are normally efficient and the presence of another video server is not necessary in this case, thanks to LabWindows.
