Wristband Measures Emotional Component

Affectiva is best known for its founding by Rosalind Picard of MIT.  We worked with them to understand the emotional responses of people to products on a shelf.  Their new innovation measures emotions through a wristband,  via skin conductivity, also called Galvanic Skin Response (GSV) presented as primary component of emotions.  But certainly not the only component.  The simplicity and portability of the method is useful.   Commonly also used for such methods as lie detectors.  More on the device, called the Q-Sensor.  Possible simple solution for neuromarketing applications?
