Okay so here is the first test of the wearable system.  This system has 3 peltier heater/coolers and 3 vibration motors.  They are located on each shoulder and at the base of the neck.  For this test it cycles through each motor and then finally the center peltier module is put into cooling for a second and then heating for a second.  The code for this test is uploaded on the project page.

Since the peltier modules are in pockets, one second of heating and cooling is not obvious to the user.  At this point, I am not sure if these will work for a user interface.  Unlike the motors which are easily detected to be on and off in a fraction of a second, it takes some time for the peltiers to heat up and cool down.  That time is even longer with a little fabric between the user and the module.  Another issue with the peltier modules is that they will work much better when I give them a good heatsink on the back.  For police, military, gamers and drivers having heatsinks on your shoulders is weird but seems do-able.   For firefighters having a heatsink into your insulated gear doesn't help much and having a heatsink into a fire environment would be a really bad idea.
