Taking advantage of free EDF Browser and free Audacity(R) programs, our EEG and ECG data set can be brought to live, and actually quite easy to read out our internal activities.
1. EEG: Audacity(R) showing EEG spectrogram and corresponding 3D accelerometer and temperature sensor data. For a whole evening: walking, dinner, video watching, book reading, meditation, sleep, meditation, breakfast and music listening. The accelerometer data show clearly how the head posture changed with each activity. The various sleep stages and patterns are also easily discernible.
