Researchers at Hong Kong Baptist University (HKBU) in China have developed a system that detects sleepy drivers and alerts them using a smartphone.
The researchers say the system uses a smartphone's real-time video to track and analyze the facial features of a driver, especially changes in eyelid and head position, which are prominent fatigue indicators.
The user has to position the smartphone near the steering wheel with the camera facing the driver.
The researchers note if the camera captures features such as drooping eyelids, drowsiness, or even nodding off, an alarm is triggered and can only be turned off manually or by voice command.
HKBU professor Cheung Yiu-ming says the system is suitable for all drivers, but could be especially advantageous for professional drivers and machinery workers who have long working hours.
Cheung also notes only a smartphone is needed, without additional devices or sensors.
