SAN FRANCISCO (Bloomberg) -- Jaguar Land Rover has applied for a U.S. patent on an invention, highlighted at the Consumer Electronics Show in Las Vegas this year, that would control a vehicle's rear window wiper through the driver's eye movement.
According to application No. 20150066293, rear-window wiper speeds are now set using a control switch that covers a preprogrammed frequency of swipes made across the window.
The disadvantage is that when the driver looks into the rear-view mirror, the window may not be clear because of the timing of the swiping cycle. Jaguar said this may be dangerous because the driver must look down and readjust the switch governing the cycle, causing a moment's inattention.
The invention uses tracking sensors to monitor the behavior of the driver and the driver's gaze. According to the application, the sensors may be installed in the vehicle's headlining, dashboard or steering wheel. The sensors may comprise a camera, an infrared sensor or an optical sensor. The automaker filed its application in March 2013.
It was not clear from reports on Wednesday if the patent has been granted final approval and spokesmen for the automakers could not be reached for comment during off hours.
According to a report on Wednesday in the UK's Daily Mail, JLR, with support from Intel and Seeing Machines, has developed sensing technology -- called the Driver Monitor System, or DMS -- that monitors the driver's face and eyes to reduce distracted and drowsy driving.
The automaker demonstrated the technology on a Jaguar F-Type prototype at this year's CES, the newspaper's website reported.
In a statement at the time, JLR said: "It is so sophisticated it can understand the state of the driver in real world conditions, including bright sunlight and if the driver is wearing glasses or sunglasses."
