- Don't need to control through Matlab! - Batteries, 1month - Fiber optic (make sure tight), 8 Sensors possible

1 The Encoders and sensors & How to attach the sensors

The Encoders (we have two so that we can encode two people at the same time) - Turn the power on - Fiber optic connection - Sensor connections (max. input of 8 sensors) The sensors (different types of sensors) - Skin conductance - Blood volume Pulse (to measure the heart rate) - Respiration (to measure the breathing rate) - EKG (Electrocardiogram, more accurate BUT need to touch the person’s chest; could be more invasive so that people don’t like it) - Temperature Attaching the Sensors to People - Blood Volume Pulse (BVP) - Skin Conductance - Respiration sensor

3 Skin conductance

What is skin conductance? Why measure skin conductance? What does skin conductance look like? Skin conductance measures - Skin conductance response (SCR) - Skin conductance level (SCL) Pre-processing of SCRs and SCLs Skin conductance measures Two ways to analyze SCRs - Magnitude - Amplitude

4 Heart Rate
