Alarm playback device, alarm playback method, and non-transitory computer readable medium

An alarm playback method, comprising the steps of:

• performing detection based on output of a sensor, output of which changes in accordance with a position or movement of an object in a determination area,
• determining whether a presence condition, which is satisfied when a user is present in the determination area, is satisfied based on detection results,
• controlling playback of an alarm sound, which is played when a time determined in accordance with an alarm time set by the user is reached, based on whether the presence condition is satisfied, and
• executing state check processing for determining whether a detection state is a normal state, wherein
• in the state check processing, a detection state is determined as a normal state when a normality determination condition including the presence condition not being satisfied is satisfied, and it is determined that a detection state is an abnormal state when the normality determination condition is not satisfied.

A non-transitory computer readable medium having recorded thereon an alarm playback program, which causes a computer to execute the steps of:

• performing detection based on output of a sensor, output of which changes in accordance with a position or movement of an object in a predetermined determination area,
• determining whether a presence condition, which is satisfied when a user is present in the determination area, is satisfied based on detection results,
• controlling playback of an alarm sound, which is played when a time determined in accordance with an alarm time set by the user is reached, based on whether the presence condition is satisfied, and
• executing state check processing for determining whether a detection state is a normal state, wherein
• in the state check processing, a detection state is determined as a normal state when a normality determination condition including the presence condition not being satisfied is satisfied, and it is determined that a detection state is an abnormal state when the normality determination condition is not satisfied.
