  Incidentally, Patent Document 1 (Japanese Patent Laid-Open No. 2001-210169) discloses an invention of a switch type notification device for facilitating operation of an operation switch of an in-vehicle device. In the invention disclosed in Patent Document 1, when a part of the human body is brought close to one of the operation switches, audio information and display information indicating the operation content of the operation switch are output, and the desired line-of-sight is maintained in the forward direction. The operation switch can be easily found.

  However, in the device disclosed in Patent Document 1, although it is possible to determine whether or not the user is a switch intended for operation, in order to perform the control for which the switch is in the state or for the purpose. No information is provided on how to operate the switch. For this reason, it is necessary to visually check the switch for the confirmation as described above, and the danger and inconvenience caused by the switch operation still remain.
