Abstract
A control method includes acquiring time information including a wake-up set time; acquiring a sleep state of a sleeper who is stimulated by a stimulation device; determining a change of the sleep state; causing the stimulation device to start increasing a stimulus which urges the sleeper to awake at a control start time as time before the wake-up set time by a predetermined time period; and controlling a change amount of the stimulus based on the change of the sleep state with the stimulus.
Claims15
A control method executed by a computer for controlling a stimulation device that outputs a stimulus, the control method comprising:
- acquiring time information including a wake-up set time;
- first acquiring a sleep state of a sleeper who is stimulated by the stimulation device;
- determining a change of the sleep state;
- causing the stimulation device to start increasing the stimulus which urges the sleeper to awake;
- controlling an increase amount of the stimulus based on the change of the sleep state with the stimulus;
- determining whether a control start time preceding the wake-up set time by a first predetermined time period has arrived;
- when the control start time is determined to have arrived, determining whether the control start time has been updated;
- when the control start time is determined not to have been updated, second acquiring the sleep state of the sleeper and updating the control start time using an adjustment value and the second acquired sleep state;
- and
- causing the stimulation device to start increasing the stimulus at the updated control start time.
A control device comprising:
- a time acquisition unit which acquires time information including a wake-up set time;
- a sleep state acquisition unit which first acquires a sleep state of a sleeper who is stimulated by a stimulation device;
- a determination unit which determines a change of the sleep state;
- and
- a stimulation control unit which causes the stimulation device to start increasing a stimulus which urges the sleeper to awake, and controls an increase amount of the stimulus based on the change of the sleep state with the stimulus, wherein
- the stimulation control unit determines whether a control start time preceding the wake-up set time by a first predetermined time period has arrived,
- when the control start time is determined to have arrived, the stimulation control unit determines whether the control start time has been updated,
- when the control start time is determined not to have been updated, the sleep state acquisition unit second acquires the sleep state of the sleeper, and the stimulation control unit updates the control start time using an adjustment value and the second acquired sleep state, and
- the stimulation control unit causes the stimulation device to start increasing the stimulus at the updated control start time.
A non-transitory computer-readable recording medium recording a program for causing a computer to execute:
- acquiring time information including a wake-up set time;
- first acquiring a sleep state of a sleeper who is stimulated by a stimulation device;
- determining a change of the sleep state;
- causing the stimulation device to start increasing a stimulus which urges the sleeper to awake;
- controlling an increase amount of the stimulus based on the change of the sleep state with the stimulus;
- determining whether a control start time preceding the wake-up set time by a first predetermined time period has arrived;
- when the control start time is determined to have arrived, determining whether the control start time has been updated;
- when the control start time is determined not to have been updated, second acquiring the sleep state of the sleeper and updating the control start time using an adjustment value and the second acquired sleep state;
- and
- causing the stimulation device to start increasing the stimulus at the updated control start time.
