Sensor talk on June 14th

Dear everybody,
As a part of the preparation of the humansensing seminar we agreed that Niels Hannibal and Morten Aagaard should wear the BodyMedia and the Polar pulsesensor. And we did.

The results have been elaborated in our spreadsheets and the numbers do we believe can be interpretated by you, the blogreader withour further comments.

Low Galvanic Sensor Response indicates either physical or mental relaxness. High value opposite. 
The figures are

 SDNN is the standard deviation in a given(NN) period. Low SDNN values indicates low HRV which indicates concentration, physical activity, stress or excitement. Low numbers are caused by concentration, physical activity, stress or excitement. High values are caused by the opposite. pnn50 is a the coefficient of heartbeats that varies more than 50 milliseconds to the previous heartbeat. Another indication of relaxedness. Low numbers are caused by concentration, physical activity, stress or excitement. High values are caused by the opposite.

 Please feel free to interpretate!
