GSR testing 1: getting a bit clinical…

Posted on | February 7, 2009 | No Comments

As I experimented in the first prototype, the pressure sensitivity drastically affects the values…which can be inevitable since stronger you grip, more contact and moisture will be. May be there are more factors I haven’t encounter……

So I decided to know more about what I am dealing with.

As Sun Tzu said in The Art of War:

If you know both yourself and your enemy, you can come out of hundreds of battles without danger.

..yes I’m not a soldier but basically the same idea :)

I had a chance to deal with a super clinical device to examine how it actually flow. First I start measuring my pulse, and then skin conductance.

After playing with my own bio feedback, I found following:

1. My voice affects the wave significantly.. is it spreading vibration over the skin?
2. Moving my fingers (especially those with sensors) does too.

Using bio feedback in environmental installation is very challenging because the subjects/participants often stay “active”. For example, they may walk, talk and move their body  in the installation field.

This is worth simulating  my work by getting several people move and talk, comparigng both calm and active status. Especially, I found the result that my voice affecting the skin conductivity very interesting…may be this is also worth researching too.
