Mightier
Mightier is a set of video games that a child plays while wearing a heart rate sensor on the arm. It grew out of a research program at Boston Children’s Hospital and Harvard Medical School, where psychologist Jason Kahn and psychiatrist Joseph Gonzalez-Heydrich built a game called RAGE-Control for kids with serious anger problems. Their company, Neuromotion Labs, now sells it as Mightier.
