Abstract: An information providing device capable of more adequately providing information regarding excretion is provided. According to one embodiment of the invention, the information providing device includes a processor. The processor acquires a first signal and a second signal. The first signal is obtained from an excretion sensor to detect excretion of a user. The second signal is obtained from a sleep sensor to detect a sleep state of the user. The processor outputs a notification signal for notifying the excretion when the first signal includes first information corresponding to a fact that the user is excreting, and the second signal includes second information corresponding to a fact that the user is awake. The processor does not output the notification signal in a first mode when the first signal includes the first information and, the second signal does not include the second information.

Abstract: According to the embodiments, the controller includes a first receiving unit and a second receiving unit, and is capable of controlling a device to be controlled. The controller is in a first mode when in a first action state prior to the first receiving unit receiving a first operation, and the controller transitions to a second mode when the first receiving unit receives the first operation. The second receiving unit is in the first optical state in the first action state. The second receiving unit is in a second optical state in a second action state prior to the second receiving unit receiving a second operation in the second mode. The second receiving unit is in a third optical state in a third action state in which the second receiving unit has received the second operation in the second mode. The second optical state differs from the second optical state. The third optical state differs from the first optical state and differs from the third optical state.
