Abstract
Disclosed herein is an apparatus for measuring a driver's visual fatigue. The apparatus includes a ground electrode that is mounted near the driver's ear, and a measuring electrode that is mounted near the driver's eye. Furthermore, the apparatus includes a controller that is configured to induce a resting potential using measured values of the ground electrode and the measuring electrode. When the resting potential is beyond a predetermined range, the controller is configured to determine the visual fatigue to be above a predetermined threshold and output a fatigue signal.
Claims8
An apparatus for measuring a driver's visual fatigue comprising:
- a ground electrode mounted at a location near the driver's ear;
- a measuring electrode mounted at a location near the driver's eye;
- and
- a controller configured to:
- induce a resting potential using measured values of the ground electrode and the measuring electrode;
- determine the visual fatigue to be above a predetermined threshold when the resting potential is beyond a predetermined range;
- and
- output a fatigue signal.
An apparatus for measuring a driver's visual fatigue comprising:
- a pair of spectacles having a nose pad, lenses, and temple arms;
- a ground electrode disposed at an end of the temple arms at a location near the driver's ear;
- a measuring electrode disposed at the nose pad at a location near the driver's eye;
- and
- a controller configured to:
- induce a resting potential using measured values of the ground electrode and the measuring electrode;
- determine the visual fatigue to be above a predetermined threshold when the resting potential beyond a predetermined range;
- and
- output a fatigue signal.
A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
- program instructions that induce a resting potential using measured values of the ground electrode and the measuring electrode
- program instructions that determine the visual fatigue to be above a predetermined threshold when the resting potential beyond a predetermined range;
- and
- program instructions that output a fatigue signal.
