Fujitsu launches wearable sensor to promote safer driving

Fujitsu has launched FEELythm, a new wearable sensor product that detects when drivers are drowsy based on their pulse to promote safer driving. Intended for use in the transportation sector, FEELythm will initially be sold in Japan from February 2015. FEELythm.

The product, which uses a proprietary algorithm developed by Fujitsu Laboratories, monitors the driver’s pulse via a sensor attached to the earlobe, gauges drowsiness based on that, and notifies the driver and the vehicle fleet manager. It can also connect to digital tachographs and other onboard devices, and link to fleet-management systems so that fleet managers can monitor the conditions of their drivers in real time and provide helpful guidance based on objective data.

The main part of the device is worn around the neck and weighs only about 90 grams, and a sensor is attached to the earlobe to measure vital signs such as pulse rate and the autonomic nervous system. Fujitsu’s proprietary algorithm determines the driver’s level of drowsiness with a high degree of accuracy, and the device gives sound and vibration alerts to the driver. The device was designed with long-haul driving in mind, with battery capacity for five continuous days of operation.

A learning function eliminates individual variability while improving accuracy.

Moving forward, Fujitsu will put to use hazard maps that compile and distill driver data and stress conditions in order to bring hazard prediction to fleet operations and expand support for driving-safety management.

Fujitsu is targeting sales of 70,000 units over next three years.
