Emotions in Hand

Apparently, we can recognize emotions with the palm of our hands. There's a system being tested at the University of Sussex that stimulates areas of the hand with ultrasound. The field is called haptics, which is a branch of psychology having to do with skin sensation. "Our findings suggest that for a positive emotion through haptic stimulation one might want to stimulate the area around the thumb, the index finger, and the middle part of the palm," interaction designer Marianna Obrist writes (story, video): http://mentalfloss.com/article/63381/you-can-feel-emotion-palm-your-hand
