Electronic device and method for determining a state of a driver
First Claim
Patent Images
1. An electronic device, comprising:
- a sensor sensing a pressure applied, by a driver, to a seat of a moving object driven by the driver; and
a processor determining that the driver is in a drowsy state in a time period, when a frequency component with respect to a change in the pressure sensed by the sensor is less than or equal to a preset threshold value.

Abstract
Electronic devices and methods are provided in which a pressure applied, by a driver, to a seat of a moving object driven by the driver is sensed. A state of the driver is determined based on frequency characteristics with respect to a change in the pressure sensed by the sensor.

13. An electronic device for detecting a state of a driver of a vehicle, comprising:
-
a sensor sensing pressures applied, by the driver, to regions of a seat of the vehicle; and a processor calculating changes in the pressures, calculating magnitude characteristics and one or more frequency components of the changes, and determining whether the driver is in a drowsy state based on a comparison of the magnitude characteristics to a first threshold value and a comparison of the one or more frequency components to a second threshold value. - View Dependent Claims (14, 15, 16, 17)
