8. A method for an information presentation apparatus that is mounted in a vehicle, the method comprising:
detecting an out-of-vehicle risk object that exists around the vehicle and potentially poses a risk to the vehicle;
detecting a gaze direction of a driver of the vehicle;
determining whether the out-of-vehicle risk object is recognized by the driver based on a detection result of the out-of-vehicle risk object and a detection result of the gaze direction; and
presenting, to the driver, out-of-vehicle risk information regarding the out-of-vehicle risk object in a presentation mode, wherein
the method further comprises:
changing the presentation mode depending on whether the out-of-vehicle risk object is recognized by the driver based on a determination result of the out-of-vehicle object;
calculating a value of an attention buffer by increasing the value of the attention buffer at a predetermined increase rate when the driver is viewing the out-of-vehicle risk object and by decreasing the value of the attention buffer at a predetermined decrease rate when the driver is not viewing the out-of-vehicle risk object;
determining whether the out-of-vehicle risk object is recognized by the driver based on the calculated value of the attention buffer; and
increasing the decrease rate when the out-of-vehicle risk object changes its behavior after the driver changed from a viewing state where the driver was viewing the out-of-vehicle risk object to a non-viewing state where the driver was not viewing the out-of-vehicle risk object.
