The prototype controller was born from research conducted in the lab of Gregory Kovacs, a professor of electrical engineering at Stanford, in collaboration with Texas Instruments. The main area of research by grad students in Kovacs’ lab involves developing practical ways of measuring physiological signals to determine how a person’s bodily systems are functioning.
One such system of interest to Corey McCall, a doctoral candidate in Kovacs’ lab, is the autonomic nervous system, the emotional part of the brain – the part that changes when you get excited or bored, happy or sad. This activity, in turn, influences your heart rate, respiration rate, temperature, perspiration and other key bodily processes. Measuring these outward signs offers a way of reverse engineering what’s occurring in the brain.
"You can see the expression of a person’s autonomic nervous system in their heart rate and skin temperature and respiration rate, and by measuring those outputs, we can understand what’s happening in the brain almost instantaneously," said McCall, the leader on the game controller project.
