Following are three short videos showing the basic functionality of the EmotiGlass breadboard prototype.

We added some backlighting (using a strip of EL material) to show the way in which the device causes selective occlusion.  The user's eyes would be on the side of the EL material looking at the scene through the liquid-crystal panels.

First is the breadboard operating in Baroreceptor-Synchronized Occlusion mode:

The pulse sensor is on Jason's finger.  We can control the occlusion pattern as well as the timing of the occlusion versus the plethysmographic signal.

Next is the breadboard being controlled to produce a window for lateralized brain stimulation (we are showing functionality of controls, rather than actual occlusion that would be used for lateralized stimulation):

Lastly, the sunglasses mode (David casts a shadow on the light sensor):
