Abstract: A method for preventing and detecting a fall of a user and implementing a system including sensors and alarm, a pair of eyeglasses with hinged stems including rims for supporting glasses, worn by the user. The sensors are set in the hinged stems and the rims of the eyeglasses. The sensors include a triaxial accelerometer, an IR transmitter and an IR receiver of infra-red light both directed to the cornea of the user, and a barometric sensor. The triaxial accelerometer signal is acquired and processed to derive a walking pace parameter, a sit to stand parameter, a head posture parameter and an acceleration magnitude over the three axes. A composite index is computed based on the walking pace, the sit to stand and the head posture parameters. The alarm is generated if the first composite index exceeds a threshold.

Abstract: A system having eyeglasses including hinged stems, a plurality of sensors and an alarm, and a method implanting the system. The system additionally includes a triaxial accelerometer, an IR transmitter, an IR receiver, and a barometric sensor. The sensors are set up in the stems and the rims of the eyeglasses and connected to a processing and calculation unit having a microprocessor and a memory. A computer program in the processing and calculation unit collects and analyzes data issued by the sensors, and triggers the alarm based on the analysis of the data.

Abstract: A system and a method implementing such a system. The system includes eyeglasses having hinged stems, a plurality of sensors and an alert alarm. The system further includes a triaxial accelerometer, an IR transmitter, an IR receiver, and a barometric sensor. The sensors are set up in the hinged stems and the rims of the eyeglasses and connected to a processing and calculation unit. The processing and calculation unit includes a microprocessor and a memory. The processing and calculation unit executes a computer program to analyze data issued by the sensors and triggers the alarm based on a result of the analyzed data.
