Information processing device, drive assist system, and drive assist method

A drive assist system comprising:

• a server device;
• and
• a drive assist device which is communicatively coupled via a communication network,
• wherein the drive assist device is configured to:
• detect an environment around a vehicle which is driven by a driver;
• and
• detect a gaze of the driver,
• wherein the server device is configured to:
• generate a hazard list of an object to be a hazard based on the detected environment;
• evaluate a risk regarding driving of the driver for each object included in the hazard list based on a frequency at which the object included in the hazard list is included in a field of view of the driver based on the detected gaze;
• and
• output drive assist information corresponding to the object with the evaluated risk that is equal to or larger than a threshold.

A drive assist method comprising:

• detecting, by a computer, an environment around a vehicle which is driven by a driver;
• generating a hazard list of an object to be a hazard based on the detected environment;
• detecting a gaze of the driver;
• evaluating a risk regarding driving of the driver for each object included in the hazard list based on a frequency at which the object included in the hazard list is included in a field of view of the driver based on the detected gaze;
• and
• outputting drive assist information corresponding to the object with the evaluated risk that is equal to or larger than a threshold.
