Description

Attention reminding device and attention reminding method Technical Field The invention relates to an attention reminding device and an attention reminding method. Background In recent years, devices for outputting information using a language corresponding to an occupant seated in a vehicle are known. For example, patent document 1 discloses a system having a function of receiving a user setting a country or language and a function of outputting information by using the set country or language. The in-vehicle information display device disclosed in patent document 2 includes a face image capturing unit that captures a face image of a user, a nationality screening unit that screens the nationality of the user based on the captured face image, a use language estimating unit that selects a call language for the user based on the screened nationality and makes a call, and estimates a language used by the user based on a result of a user's answer to the call, and a display control unit that displays a display screen understandable by the user using the estimated use language. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2022-056875 Patent document 2 Japanese patent application laid-open No. 2019-113520 Disclosure of Invention Problems to be solved by the invention In the case of notifying the driver of the presence of risk, there is a problem that the driver is notified not only by text but also by a plurality of methods using, for example, sound, color, or the like, so that erroneous recognition of the driver is suppressed as much as possible.
