INFORMATION NOTIFICATION APPARATUS AND INFORMATION NOTIFICATION METHOD
First Claim
1. An information notification apparatus comprising:
- a camera configured to capture an image of a driver of a vehicle;
a memory; and
a processor coupled to the memory and configured to;
perform line-of-sight detection based on the image captured by the camera;
calculate a forward gaze degree of a gaze of the driver in accordance with a line-of-sight direction obtained in the line-of-sight detection, the forward gaze degree indicates whether the gaze of the driver is within a predetermined area of a direction in which the vehicle is traveling;
provide a notification to the driver in a first information when the forward gaze degree is lower than a first threshold; and
provide the notification to the driver in a second information when the forward gaze degree is higher than or equal to the first threshold, the second information includes less than the first information.

Abstract
An information notification apparatus includes a camera; a memory; and a processor coupled to the memory and configured to perform line-of-sight detection on an image captured by the camera, calculate a forward gaze degree of a gaze directed to a predetermined area in accordance with a line-of-sight direction obtained in line-of-sight detection; execute a notification to an outside in a first information if the forward gaze degree is lower than a first threshold; and execute the notification in a second information which information is less than the first information if the forward gaze degree is higher than or equal to the first threshold.

10. An information notification method comprising:
-
capturing, with a camera, an image of a driver of a vehicle; performing, with a processor, line-of-sight detection based on the image captured by the camera, calculating, with the processor, a forward gaze degree of a gaze of the driver in accordance with a line-of-sight direction obtained in line-of-sight detection, the forward gaze degree indicates whether the gaze of the driver is within a predetermined area of a direction in which the vehicle is travelling; providing a notification to the driver in a first information when the forward gaze degree is lower than a first threshold; and providing the notification in a second information when the forward gaze degree is higher than or equal to the first threshold, the second information includes less information than the first information.

11. A vehicle-mounted apparatus to provide notifications to a driver, the vehicle-mounted apparatus comprising:
-
a notification device configured to present notifications to the driver of a vehicle in a plurality of forms based on a workload of the driver; a memory; a processor coupled to the memory and the at least one notification device, the processor configured to; acquire a travelling direction of the vehicle; perform line-of-sight detection to determine a line-of-sight for the driver; calculate a gaze degree associated with the driver, the gaze degree indicating frequency of the determined line-of-sight of the driver included within a predetermined range of the travelling direction of the vehicle; classify the workload of the driver as low when the calculated forward gaze degree is lower than a threshold; classify the workload of the driver as high when the calculated forward gaze degree is higher than the threshold; provide a notification to the at least one notification device in a first information when the workload of the driver is classified as low; and provide the notification to the at least one notification device in a second information when the workload of the driver is classified as high, the second information includes less information than the first information. - View Dependent Claims (12)
