Action monitoring system and action monitoring method

An action monitoring system configured to monitor an action of a monitoring target person living in a residence, the action monitoring system comprising:

• multiple occupancy sensors provided in places different from each other in the residence, the multiple occupancy sensors being configured to detect the monitoring target person;
• a storage section configured to store data;
• and
• a determination section configured to;
• store, in the storage section in advance, a specific action defined by a reaction order of the multiple occupancy sensors corresponding a movement of the target person among the places that correspond to the respective multiple occupancy sensors and a predetermined execution time of the reaction order corresponding to the specific action,
• store a reaction time as reaction data in the storage section when any of the multiple occupancy sensors reacts, extract a current action based on the reaction data stored in the storage section by comparing a sequence and a time of the reactions, and
• compare the current action with the specific action to determine whether the specific action has been performed by comparing the sequence and the time of the reactions to the reaction order and the predetermined execution time.
