Title: GLASSES COMPLIANCE MONITOR AND ASSOCIATED METHOD
Abstract:
A compliance monitor for wear on a head includes a data logger with processor, and memory containing firmware; with sensors that may include one or more of magnetometers, accelerometers, gyroscopes, and temperature sensors. The firmware is adapted to process sensor readings to determine intervals where the compliance monitor is attached to a person's head, and in embodiments is adapted to scan for signatures indicating donning of the compliance monitor. The method of determining wear of a head-mounted device by a person includes determining differences between a magnetic field measured at the start of a time interval and the time interval, differences between a temperature reading at a sensor on a head side of the head-mounted device and on an ambient side of the head-mounted device, accelerations of the head-mounted device indicative of wear, and rotations of the head-mounted device indicative of wear
