The advice information to be classified into items and practiced for each item is acquired from the database 12 and displayed on the monitor 4 of the personal computer B.

  Specific examples of advice information that should be put into practice are the contents of daily eating and drinking, the time to eat and drink, the time of bathing, the part of the massage performed by yourself, the time to continue the massage, the time and time to relax It is information such as belts. This advice information is stored in advance in the database 12 in the form of a message (document data).

  The feature of the present invention is to clarify what kind of processing is selected for the advice information when the advice information is displayed on the monitor 4. This processing mode will be described below.

[Process type]
The processing mode in the sleep improvement apparatus of the present invention can be shown as in the flowchart of FIG. This flowchart shows the control mode of the sleep improvement program of the present invention.

  In the first embodiment, after the user enters the bed 1 and operates the sleep switch SW, the sleep state of the user in the bed 1 is represented by the heart rate sensor S1, the sleep condition sensor S2, the body motion sensor S3, and the snoring sound sensor S4. Information corresponding to each sensor is acquired by the main control unit A and stored in a storage such as a nonvolatile memory or a hard disk. Further, the above SW operation does not have to be performed manually. For example, the bed operation is detected from the information of each sensor in the bed 1 and the sleep switch SW is automatically operated. Is also possible.

  Thus, since the sleep information at the time of the user's sleep is stored in the main control unit A, in this control, first, when the user's operation performs a predetermined operation on the personal computer B, the personal computer B communicates with the communication means. Is connected to the main control unit A via (login), and the measurement result (sleep information) of the set period is acquired (step # 101).

  This measurement result is acquired by the measurement information acquisition unit 31, and based on the acquired information, the state of “apnea” during sleep, the status of “snoring”, “degree of bed separation”, and “sleep time” And the sleep evaluation part 32 performs the process which gives an evaluation value with a point (numerical value) with respect to "sleep depth" and the time to "sleep" (step # 102). As the evaluation value, a larger value (100 points is the maximum value) is given as the quality of sleep is better.

  You may perform the process which gives a point in any of the sleep information acquisition part 11, the main control unit 13, and the terminal control unit 22. FIG. Further, information serving as a reference when giving points or information serving as a table may be acquired from the database 12.

  From the measurement results obtained in this way, for example, an average value for three days or an average value for one week is obtained, and the display control unit 23 displays the radar chart RC and the measurement history on the monitor 4 as shown in FIGS. Display (step # 102).

  When performing this evaluation, a measurement result area 41, a history area 42, and an advice area 43 are formed for the monitor 4. The radar chart RC is displayed in the measurement result area 41, the history is displayed in the list display area 42A of the history area 42, and the current advice information is displayed in the advice area 43.

  Specifically, in the measurement result area 41, six items of “apnea”, “snoring”, “degree of getting out of bed”, “sleeping time”, “sleeping depth”, and “sleeping” are evaluated in the form of a radar chart RC. The value and the previous evaluation value are displayed in a superimposed form.

  In the history area 42, six items, “apnea”, “snoring”, “degree of getting out of bed”, “sleeping time”, “sleeping depth”, and “sleeping”, are evaluated against the list display area 42A this time, the previous time and the last time. The value is displayed numerically.

  When the radar chart RC is displayed and when points are displayed as evaluation values in the history area 42, the points having 70 to 100 are displayed in blue (things with good sleep quality). Is done. Further, the display is performed in green for points 50 to 69, yellow for points 30 to 49, and red for points 0 to 29.

  As will be described later, advice information is not output for items having points of 70 to 100. Advice information is output for other points.

  The quality of sleep is determined from the points of each item from the information thus obtained, and if all are good (70 to 100 points), a message indicating that the sleep is good is set (steps # 103 to 105). The set information is displayed on the monitor 4 and the displayed information is stored in the personal computer B (steps # 111 and # 112).

  As a specific example of the message displayed in this process, a message such as “Please maintain this state because the result is good this time” is set as shown in FIG.

  In this sleep quality determination, the sleep evaluation unit 32 is a value (threshold value) in which points of six items such as “apnea”, “snoring”, “bedroom”, “sleeping time”, “sleep depth”, and “sleeping” are set. Judgment is made based on whether or not.

  If some of the sleep qualities determined by the sleep evaluation unit 32 based on the points of each item are not good, the display candidate selection unit 33 selects a display candidate of advice information (an example of an output candidate). (Step # 106).

  When selecting this advice information display candidate, (1) the point corresponding to the item whose point is less than the set value, and (2) the low point when there are a plurality of items whose point is less than the set value Item (3) Information indicating that the practice will continue for items whose points have been improved since the previous time, (4) For those whose points have been DOWN since the previous time, information for confirming the presence or absence of the practice will be displayed, and the user will be displayed. When the confirmation is input from the keyboard 3, the same item as the previous one is selected as a display item (an example of a program selection function).

  Next, the personal information acquisition unit 34 displays a message (not shown) for prompting input of personal information on the monitor 4. Based on this message, the user inputs a name and identification information for identifying the user himself / herself from the keyboard 3, whereby the gender, age, preference, etc. of the user are specified based on the input personal information (step # 107). ).

  In this way, the display candidate of the advice information is selected in step # 105, and furthermore, the user's sex, age, preference, etc. are acquired from the personal information, so that the display candidate is handled from the database 12 based on such information. Advice information is acquired. Then, the acquired advice information having a low difficulty level is set as a display target (an example of setting function of # 108 step program).

  In order to realize such processing, it is necessary to store information such as the user's sex, age, and preference in association with personal information. Moreover, the process which narrows down the display object based on information, such as sex, age, and preference, from the display object of the some advice information already selected is implement | achieved.

  The database 12 stores advice information that can be classified into six types corresponding to the six items described above. The six types of advice information are document information indicating contents that can be performed by the user in order to improve sleep corresponding to the six items described above, and are assigned difficulty level information and index information.

  The difficulty level information can be described as, for example, information obtained by classifying the difficulty level into three levels. Since the advice information has such a structure, a display target is set based on the difficulty level information attached to the advice information.

  When advice information is set as a display target in this way, it is determined whether or not the display target is the previous display, and if it is the same as the previous display, Set a low degree (a little difficult) as the display target. If the information is not displayed last time, the information set in step # 108 is maintained.

  Thereafter, the set advice information is displayed on the monitor 4 by the display control unit 23, and the displayed information is stored in the personal computer B (steps # 111 and # 112). Step # 111 is an example of a program output function.

  In the advice area 43, information for improving sleep is displayed for six items of “apnea”, “snoring”, “degree of bed separation”, “sleeping time”, “sleeping depth”, and “sleeping”.

[Second Embodiment / Basic Configuration]
In the second embodiment, the basic configuration of the main control unit A, the personal computer B, and the display terminal C is not different from that of the first embodiment. The difference is that the main control unit A performs processing in the information processing block 30 which has been performed in the personal computer B in the first embodiment.

  That is, as shown in FIG. 6, the main control unit A includes a sleep information acquisition unit 11, a database 12, a main control unit 13, and a main transmission / reception unit 14. In addition, an information processing block 30 for accessing information with the main control unit 13 is provided.

  Further, it is assumed that information communication means between the main transmission / reception unit 14 and the personal computer B is constituted by a wireless LAN. Also in the second embodiment, a communication unit using infrared rays, a communication unit using dedicated radio, or a wired communication unit using a communication cable may be used.

It is configured. These have the same functions as those described in the first embodiment, and the control mode also performs the same processing as the flowchart shown in FIG.

  Also in this process, when acquiring information for sleep improvement, the main control unit A connects to the main control unit A via the communication means from the personal computer B, and requests the process, so that the main control unit A becomes the sleep information acquisition unit. By acquiring sleep information (measurement result) from 11 and transmitting it to the personal computer B, the radar chart RC and the measurement history are displayed on the monitor 4.

  Thereafter, the main control unit A determines the quality of sleep from the sleep information, and selects display candidates for advice information. When acquiring personal information, the main control unit A displays a message (not shown) for prompting input of personal information on the monitor 4, and the individual input by the user inputting information corresponding thereto Information is transmitted to the main control unit, and based on this information, the gender, age, preference, etc. of the user are specified.

  Further, advice information is acquired, a low difficulty level is set as a display target, and a display target is narrowed down based on information such as gender, age, and preference. When advice information is set as a display target, a determination is made as to whether or not the display target is displayed last time. Set a display object that is low (a little difficult). In addition, when it is not displayed last time, already set information is maintained.

[Another embodiment]
The present invention may be configured such that advice from an external server or sleep specialist can be acquired and stored in the database 12 via communication means such as the Internet or WAN.

  In addition, a process may be added in which sleep information is transmitted to an external server or a sleep specialist through the communication means to obtain advice and the advice information can be displayed on the monitor.

  The sleep improvement device is configured so that items to be evaluated for sleep can be arbitrarily changed. When configured in this way, it is possible not only to analyze the sleep situation from different viewpoints, but also to improve sleep according to the sleep situation based on the analysis result.

[Effect of the embodiment]
Since it comprised in this way, the user should just sleep in the condition where the sleep condition is measured with sensors in the bed 1. When sleep improvement is performed, the personal computer B is connected to the main control unit A, and an operation for inputting necessary information is first performed.

  By performing such an operation, information indicating the state of sleep is displayed in the form of a radar chart RC on the measurement result area 41 of the monitor 4, and numerical values are displayed on the list display area 42A of the history area 42. As a result, it is possible to visually grasp the sleep state easily.

  Then, advice information corresponding to an item to be improved with priority among a plurality of items is displayed in the advice area 43 of the monitor 4 as document data. According to this display, for example, changing sleep / bath time or practicing massage can improve sleep.

  In particular, the advice information displayed in this way is not only appropriate to reflect the user's personal information, but also automatically selects and displays the easiest to practice according to the difficulty level. It becomes easy to improve sleep.

  Also, when displaying advice information, if it overlaps with the previous one, avoid duplication and display the next less difficult, so it is possible to improve sleep from a different perspective Become.
