A test was carried out by the National Scientific Research Centre (CNRS) in France to test the efficiency of the StopSleep device. The device is believed to have the ability to detect the initial signs of drowsiness as well as when an individual is asleep. The initial signs included continuous decline in awareness and concentration while the sleepiness implied major reduction in awareness and concentration.

The device was of interest to CNRS due to the fact that a lot of accidents were as a result of drowsiness and sleepiness. Many studies have proven that a large percentage of accidents are as a result of driver fatigue which leads to a decrease in concentration, drowsiness and sleeping while driving. CNRS also stated the fact that drowsy and sleepy drivers are not only a risk to themselves but also a risk to other road users. It was thus believed that if StopSleep passed the test, it could be a useful device in reducing the rate of deaths and injuries, resulting from accidents in France and all over the world.

The test which began at about 10:00pm had each of the participants fitted with an eye tracker which was the monitor the movements and positions of the eye, encephalogram which was to record the activities of the brain and StopSleep device. They were to listen to different random sounds every second for over 30 minutes. The participants were expected to respond to the sound as soon as they heard it in order to monitor their reaction and performance time.

Another test was carried out to check if the StopSleep device made false alarms when the individuals were neither drowsy nor sleepy. The test had a total of 10 participants. The StopSleep device was able to satisfactorily pass the CNRS test and is recommended for drivers all over the world to help eliminate the risk of sleeping off while driving.
