2. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 Biofeedback analyzing system in a Server/Client environment. Giving a person some quantification of his stress levels in real time This is done by constantly measuring a person' bio-signals (such as pulse, skin-resistance, palm temperature

3. System description המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 3 Our system is based on a client-server framework. It allows clients connect to a set of sensors, measure their bio- signals, which are then passed to the computer using simple lightweight adaptor hardware Track his stress levels on the computer screen. The skin resistance, and palm temperature measurements are then Sent to a server. The server machine allows tracking large numbers of clients at once. Monitor their measurements graphs and then save it in a log file. Signal filtering can be easily modified or even dynamically suited to each individual and just "switched into" the system.
