AutoPlus No.1363. 17th October 2014
In an article on driver fatigue, testers were asked to review different anti-sleep alarms available on the market.
The verdict : StopSleep was simply the best solution based on performance quality and value for money.
StopSleep review :
StopSleep is a double ring which you can wear on any two fingers of either hand. It analyses the electrodermal activity of your skin, looking for changes in activity of the sweat glands and your nervous system. This technique, the same technique as used in lie detectors, can detect any drops in concentration and the on-set of drowsiness, micro-sleep and eventually sleep.
In use :
The ring is worn across two fingers and although this can feel strange at first, it quickly feels
normal over a long journey. It’s not possible to charge the ring whilst in use, but it can be
charged in advance via a micro USB cable and fortunately has a long battery life of up to
15hrs, more than adequate for most journeys.
AutoPlus verdict : Efficient and usable by everyone, anywhere.
StopSleep produces two levels of alert: a single vibration alerts to a slight drop in
concentration and awareness and a second more pronounced alarm, combining a loud beep
and vibration, alert when there is a sign of a greater drop in concentration and driver fatigue.
Benefits: the alarms are accurate and alert at the appropriate times, genuinely recognising
drops in concentration, awareness and the on-set of drowsiness and driver fatigue. Only a
change in temperature, causing the user to sweat suddenly can create a false alert, making
StopSleep very effective. In our view, StopSleep is by far the best quality and value for
money anti-sleep alarm on the market.
“StopSleep wakes you up”
The ring that wakes you up.
The built-in sensors of this device, which you wear on two fingers of your
hand, monitors driver awareness and alerts at the first signs of a drop in
concentration and awareness.
Its sporty looks might suggest that this device measures your heart rate or the number of
calories burned during an exercise routine. In fact, the StopSleep ring monitors a driver’s
awareness, and if the driver starts to lose their concentration it will alert them immediately
via a built-in vibrating alarm and beeper. StopSleep weighs only 20g, and is available
through 2KD France. It allows motorists to monitor their own level of concentration and
fatigue, before the first physical signs occur: itchy eyes, stiffening of the neck, glazed eyes
and heavy eyelids. A danger to be taken very seriously, driver fatigue is responsible for one
in three fatal accidents on the highway and increases the risk of accidents in general by
Two warning levels
This rechargeable ring, is worn between index and middle fingers on either hand. Its eight
sensors calculate electrodermal activity (Electrical activity recorded at the surface of the
skin), which actually reflects brain activity. "It's the same principle of that used by lie
detectors. When a person lies, the activity of the brain registers ‘peaks’, as his electrodermal
activity increases. At StopSleep, we measure the ‘downturns’ "says John Toquet, co-founder
of 2KD France.
StopSleep, whose effectiveness has been tested by the National Centre for Scientific
Research, has a two stage alarm system. The first stage comes in the form of a vibration
and will alert you if your awareness and concentration has reduced, this is sometimes so
subtle you may not have even noticed until StopSleep alerts. The second alert is more
serious and combines the vibration with a loud beep indicating that your awareness and
concentration had dropped significantly. As this point "It is strongly advised you stop," said
John Toquet. However even if your StopSleep did not beep, remember to take at least a
fifteen minute break for every two hours of driving.
Other devices, such as the onboard camera system - which calculates the blinking of the
eyelids on the Ford Focus - or Attention Assist system from Mercedes-Benz - studying the
trajectory of the vehicle – are also used to assess the risk of drowsiness, but StopSleep ring
has the advantage that it can be taken from vehicle to vehicle and used in a number of
different circumstances. 2KD France also points out that the ring "could also be used for
people whose profession requires great concentration” says John Toquet. “In particular, air
traffic controllers and the military” We tested it during a working day: it vibrated after three
