1. An attention attracting system comprising:
HMI devices that are mounted on a subject vehicle; and
an attention attracting device comprising a processor that transmits, to a driver, a possibility of contact between the subject vehicle and an object through the HMI devices, wherein
the HMI devices include a tactile HMI device, an auditory HMI device, and a visual HMI device, the tactile HMI device providing a stimulus to a tactile perception of the driver, the auditory HMI device outputting sound to the driver, the sound serving as an auditory stimulus, the visual HMI device transmitting visual information to the driver,
the processor of the attention attracting device provides a risk identification section, a fatigue estimation section, and a transmission section, wherein:
the risk identification section identifies a risk position and a risk level, the risk position being a position having a strong possibility of contact occurring between the subject vehicle and the object in an environment surrounding the subject vehicle, the risk level being a degree of the possibility of the contact occurring at the risk position,
the fatigue estimation section estimates a degree of fatigue of the driver, and
the transmission section transmits the risk position and the risk level to the driver, and
the transmission section
selects the HMI device to be used in accordance with the degree of fatigue of the driver,
provides a tactile stimulus or an auditory stimulus to the driver through the tactile HMI device or the auditory HMI device at a remarkableness level corresponding to strength of the possibility of the contact indicated by the risk level, and
transmits visual information to the driver through the visual HMI device, the visual information indicating a direction of the risk position viewed from the driver.
