Physiatrist Dr. Jiunn-Horng Kang has the calm demeanor of someone used to reassuring patients. At the same time, a somewhat mischievous smile and glasses make seem like he’s just as at home at a video game exhibition as at a patient’s bedside. Between his time as a physiatrist, researcher, and associate professor, he has his assistants and students test out popular tech devices to find discrepancies between interpretations of physiological data and people’s real-world experiences. On his wrist is a new model smartwatch. “I wear a lot of watches to see the signals I can get from different devices. Actually, in our lab we have more than ten kinds of watches.”
