Abstract: A subject is to provide a vehicle information transmitting device capable of more clearly transmitting information to a driver. In the present embodiment, a virtual image for attracting attention in which a variation amount per unit change of color or luminance is set small is appeared under a situation where a relative deceleration of an object, i.e. a preceding vehicle, is small and thus attention attracting is necessary. A virtual image for warning in which the variation per unit change of color or luminance is set large is appeared under a situation where the relative deceleration of the object is large and thus warning is necessary.

Abstract: Disclosed is a biological body state assessment device capable of accurately assessing an absentminded state of a driver. The biological body state assessment device first acquires face image data of a face image capturing camera, detects an eye open time and a face direction left/right angle of a driver from face image data, calculates variation in the eye open time of the driver and variation in the face direction left/right angle of the driver, and performs threshold processing on the variation in the eye open time and the variation in the face direction left/right angle to detect the absentminded state of the driver. The biological body state assessment device assesses the possibility of the occurrence of drowsiness of the driver in the future using a line fitting method on the basis of an absentminded detection flag and the variation in the eye open time, and when it is assessed that there is the possibility of the occurrence of drowsiness, estimates an expected drowsiness occurrence time of the driver.

Abstract: A drowsiness detector capable of detecting light drowsiness of a subject with high precision is provided. The drowsiness detector acquires the measurement data of a measurement device first, and acquires a value of the pulse rate by performing preprocessing on the measurement data and extracts a pulse fluctuation from the value of the pulse rate. Then, the drowsiness detector sets the reference section width of the pulse feature value referred to in order to acquire the standard deviation of the pulse feature value (value of the pulse rate and pulse fluctuation) and then calculates the standard deviation value of the pulse feature value in the reference section width and acquires the corrected standard deviation value of the pulse feature value by dividing the standard deviation value of the pulse feature value by the pulse feature value. Then, the drowsiness detector determines whether or not the driver is lightly drowsy using the corrected standard deviation value of the pulse feature value.

Abstract: Provided are a physiological condition estimation device and a vehicle control device capable of preventing an error in the operation of an apparatus, such as a vehicle, and improving the safety of the operation of the apparatus. The physiological condition estimation device includes an eye-open time acquiring unit that acquires the eye-open time of the driver, a variation calculating unit that acquires a variation in the eye-open time acquired by the eye-open time acquiring unit, and a drowsiness predicting unit that determines the physiological condition of the driver on the basis of the variation in the eye-open time acquired by the variation calculating unit. In this way, since the physiological condition is determined on the basis of the variation in the eye-open time, it is possible to detect a slight reduction in the arousal level and estimate a significant reduction in the arousal level to a value that will cause an error in the driving of the vehicle in the future.
