| Popis: | Background: Simulation training in medical education is a valuable tool for skill acquisition. Standard audio/video-feedback systems for training surveillance and subsequent video feedback are expensive and often not available. Methods: We investigated solutions for a low-budget audio/video-feedback system based on consumer hardware and open source software. Results: Our results indicate that inexpensive, movable network cameras are suitable for high-quality video transmission including bidirectional audio transmission and an integrated streaming platform. In combination with a laptop, a WLAN connection, and the open source software iSpyServer, one or more cameras represent the easiest, yet fully functional audio/video-feedback system. For streaming purposes, the open source software VLC media player yields a comprehensive functionality. Using the powerful VideoLAN Media Manager, it is possible to generate a split-screen video comprising different video and audio streams. Optionally, this system can be augmented by analog audio hardware. In this paper, we present how these different modules can be set up and combined to provide an audio/video-feedback system for a simulation ambulance. Conclusions: We conclude that open source software and consumer hardware offer the opportunity to build a low-budget, feature-rich and high-quality audio/video-feedback system that can be used in realistic medical simulations. |
