1. An information processing device comprising:
control circuitry configured to:
perform detection processing for an object on a periphery of a mobile device; and control a feature quantity of a first warning sound, the first warning sound indicating presence of the object, and a position of a sound image of the first warning sound, according to a position of the detected object,
wherein the control circuitry:
estimates a danger degree of the object,
wherein the estimated danger degree of the object is zone specific such that the object is estimated to have a first danger degree when the mobile device is in a first zone, and a second danger degree when the mobile device is in a second zone previously determined to have a higher degree of danger than the first zone,
controls the feature quantity of the first warning sound according to the estimated danger degree of the object,
estimates which of a possibility of the mobile device causing harm to the object and a possibility of the mobile device being subjected to harm by the object is higher, and varies the feature quantity of the first warning sound between a case where the possibility of the mobile device causing harm to the object is higher and a case where the possibility of the mobile device being subjected to harm by the object is higher,
based on multiple objects being detected, determines whether the multiple objects are traveling in a column, and
based on the multiple objects being determined to be traveling in a column, regards the multiple objects as one object, and performs control to output the first warning sound, otherwise performs control to output multiple first warning sounds each indicating presence of a corresponding one of the objects at a same time.
