Description

The present invention relates to an alarm clock and a wake-up method that reliably promises to wake up by detecting a person's biological information during sleep and detecting a wake-up state.

  2. Description of the Related Art Conventionally, alarm clocks have been incorporated with a mechanism for making an alarm sound at a set time, and at the same time adding various ingenuity to wake up reliably.

For example, Patent Document 1 discloses a technique for emitting an alarm sound after stimulating the brain by releasing a wake-promoting substance in order to promote a pleasant awakening. (Prior art 1)
Japanese Patent No. 634164 (page 2, FIG. 1) Patent Document 2 discloses a technique for producing a sound with entertainment by using a pocket watch that incorporates a pachinko machine of play equipment. (Prior art 2) Japanese Utility Model Publication No. 7-25741 (2-3 pages, FIGS. 1-6)

However, in the prior art 1 and the prior art 2, since the alarm sound is manually stopped at the set time, the alarm sound is stopped unconsciously, and the sleep state is again resumed. There was a problem that it entered and did not play its original role.

The present invention has been made in view of such a conventional technique, and an object of the present invention is to provide an alarm clock that wakes up reliably.

The present invention solves the above problems by the following means. That is, the invention of claim 1 wakes up time setting means for setting and holding the time of awakening, clock means for outputting time information including the current time, wakefulness stimulation start means for issuing awakening stimulus start instruction, When the biological information detecting means for detecting and recording the biological information of human, the wakefulness information extracting means for extracting and recording the wakefulness information from the waveform and frequency of the biological information, and when the wakefulness information reaches a predetermined condition, Awakening detection awakening comprising: awakening stimulation stopping means for issuing awakening stimulation stop instruction; and awakening stimulation means for receiving awakening stimulation stop instruction and receiving awakening stimulation stop instruction to stop the awakening stimulation. When it is time to wake up, the wake stimulus means receives the wake stimulus start instruction and starts giving the wake stimulus to the sleeping human, and the wake stimulus stop means performs the wake stimulus. Receiving When arousal information of the detected biometric information from the person reaches a predetermined condition, to issue a wake stimulation stop instruction, an arousal detection waking timepiece, characterized in that stopping the awakening stimulation means.

  Therefore, the awakening detection alarm clock can continue stimulation (alarm sound) until a sleeping human awakens (wakes up).

The invention according to claim 2 is a wake-up time setting step for setting and holding a wake-up time, a clock step for outputting time information including the current time, and a wake-up that stimulates a sleeping human when the wake-up time is reached. A stimulus step, a wake-up information extraction step of detecting wake-up information from the waveform and frequency of the wake-up information and recording it, and a wake-up stimulus stop instruction when the wake-up information reaches a predetermined condition Is a wakeup method for detecting wakefulness, comprising: a wakeup stimulus stop step for issuing a wakeup stimulus, and a wakeup stimulus step for receiving a wakeup stimulus stop instruction to stop the wakeup stimulus.

  According to a third aspect of the present invention, there is provided a computer program that causes a computer to operate as the awakening detection alarm clock according to the first aspect by being incorporated in the computer.

A fourth aspect of the present invention is a computer-readable recording medium on which the computer program according to the third aspect is recorded.

According to the present invention, since it continues to ring until it is detected that a sleeping human has awakened, it is possible to wake up from sleep reliably.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a detailed configuration diagram of an awakening detection alarm clock. The awakening detection alarm clock 100 includes biological information detection means 110, awakening information extraction means 120, clock means 130, awakening time setting means 140, awakening stimulation means 150, awakening stimulus start means 160, and awakening stimulus stop means. 165.

  The biological information detection unit 110 detects and records human biological information (for example, brain wave data). The awakening information extraction unit 120 extracts and records awakening information (for example, α (alpha) wave component) from the waveform and frequency of biological information (for example, brain wave data). The clock means 130 outputs time information including the current time. The wake-up time setting means 140 sets and holds the time when the human wakes up (for example, the wake-up time). The awakening stimulating means 150 stimulates a human being sleeping (for example, an alarm sound). The awakening stimulus start means 160 issues an awakening stimulus start instruction. The wakefulness stimulus stop means 165 issues a wakefulness stimulus stop instruction when the wakefulness information reaches a predetermined condition (for example, a predetermined reference value or less).

  The biological information detection unit 110 is a sensor. Awakening stimulating means 150 and an acoustic speaker. The wakefulness information extracting means 120, the clock means 130, the wakefulness time setting means 140, the wakefulness stimulus starting means 160, and the wakefulness stimulus stopping means 165 are computer programs.

FIG. 2 is a flowchart of 100.
(1) The wake-up time setting means 140 sets and holds the wake-up time. (Step S110)
(2) The current time of the time information output from the clock means 130 is compared with the alarm time. When it is time to wake up, go to the next step. If the current time is before the wake-up time, the process returns to the top of this step. (Step S120)
(3) The wakefulness stimulation start means 160 issues an wakefulness stimulus start instruction, and the wakefulness stimulation means 150 receives the wakefulness stimulus start instruction and emits an alarm sound. (Step S130)
(4) The biological information detection unit 110 detects and records brain wave data. (Step S140)
(5) The awakening information extraction unit 120 extracts and records an α wave component having a frequency of less than 8 to 13 Hz from the waveform and frequency of the electroencephalogram data. (Step S150)
(6) The waveform (amplitude) of the α wave component is compared with a predetermined reference value. If the amplitude of the α wave component falls below a predetermined reference value, the process proceeds to the next step. If the amplitude of the α wave component is equal to or greater than a predetermined reference value, the process returns to step (4). (Step S160)
(7) The wakefulness stimulation stop means 165 issues a wakefulness stimulation stop instruction, and the wakefulness stimulation means 150 receives the wakefulness stimulation stop instruction and stops the alarm sound. (Step S170)

Instead of the alarm sound, it is possible to stimulate the living body such as fragrance, wind, flashing light, and temperature change.

Further, the same effect can be obtained by using a β (beta) wave component (13 to less than 40 Hz) of the electroencephalogram data together with the α wave component.

As explained in detail above, according to the present invention, the alarm clock can be awakened reliably in order to continue to sound until it is sounded at a set time and it is detected that a person has been awakened reliably. It became.
