Labeled Raw PPG Signals Measured Using Wearable Sensor-kit

<p>This data is part of the <em>Wearable Sensor-kit to Characterize Affect</em> project. It was measured using an Arduino-based wireless, wearable device that consists of several biosensors attached to a wrist brace. It was designed and built for the purpose of measuring students' biometrics. </p>

<p>The PPG signals were measured using <em>Asiawill Pulse Heart Rate Sensor Module</em> from the ring finger of the left hand for nine healthy participants in a still seated position. The duration of data acquisition varied between 20 to 40 minutes. </p>

<p>PPG signals consist of systolic and diastolic peaks. The interval between two systolic peaks corresponds to one heart pulse. We labeled the PPG heart pulses as "good" or "bad" based on the presense of the peaks as follows: </p>

<ul>
<li>A "good" pulse is when both systolic and diastolic peaks are identifiable. The pulse is assigned to class "1"</li>
<li>A "bad" pulse is when either of the peaks is missing or if the signal is very noisy. The pulse is assigned to class "0".</li>
</ul>
