The Ford Motor Company has invented the SafeCap, which will alert drivers to their drowsiness.
The cap is aimed at truck drivers, but could be used by anyone.
They mapped the typical head, neck and shoulder movements of drivers and equipped the cap with a gyroscope and accelerimeter to detect atypical movements indicating sleepiness.
When these are detected, a sound is emitted--followed by light and vibration.
By heading off accidents due to the driver nodding off, the company hopes to reduce deaths and injuries.
Look for this in 2018.
