The technology can track the emotional responses individuals with a degree of accuracy at range, whether or not they happen to be in view of a camera or other sensor. This capability might enable a comedian or politician to literally feel the room during a public engagement, or a peace officer to read subdued agitation or panic in a suspect. The campus security-related capabilities might be substantial also, notwithstanding privacy rights. Folks experiencing a nervous breakdown in a car-park stairwell, a barely-contained rage at the DMV, the thrill of shoplifting, or an amorous liaison in a supply closet, may soon find themselves quickly and automatically rumbled.
