(Assignment process)
Next, an example of device assignment processing for the pressure sensor, which is executed by the control unit 170 of the pillow side device 100, will be described with reference to FIG.

  In the process of FIG. 4, first, in step S <b> 10, the control unit 170 determines whether or not human body communication with the futon-side device 200 is established. If the determination here is negative, that is, if the user is not sleeping on the mattress 20 and human body communication between the pillow side device 100 and the futon side device 200 is not established, the control unit 170 repeats the process of step S10 until human body communication is established. Then, at the stage where the human body communication is established between the pillow side device 100 and the futon side device 200, the determination in step S10 is affirmed, and the control unit 170 proceeds to step S12. It is assumed that the user is lying in a state as shown in FIG. 2 at the stage of moving to step S12. In this case, human body communication between the pillow side device 100 and the futon side device 200 is established by the user contacting the electrode portion 141B of the pillow side device 100 and the electrode portions 211A and 211B of the futon side device 200.

  If transfering it to step S12, the control part 170 will recognize the pressure sensor which a user can contact. In this case, the control unit 170 recognizes a pressure sensor that can be contacted by the user based on the contact state between the electrode units 141A and 141B and the electrode units 211A and 211B and the user. For example, in the state of FIG. 2, since the user is in contact with the electrode unit 141B and the electrode units 211A and 211B, the control unit 170 controls the pressure sensors 130A and 130B of the pillow side device 100 and the futon side device 200. The pressure sensors 230A to 230D are recognized as pressure sensors that can be contacted by the user. In addition, for example, when the user is in contact with the electrode unit 141B and the electrode unit 211A but not in contact with the electrode unit 211B (such as when the user is short), the control unit 170 includes the pressure sensor 130A. , 130B and the pressure sensors 230A, 230C are recognized as pressure sensors that can be contacted by the user.

  In step S12, the control unit 170 stores information on pressure sensors that can be contacted by the user in the memory 160 as a pressure sensor information table as shown in FIG. The pressure sensor information table in FIG. 5 includes items of “update date and time”, “sensor name”, “sensor position”, and “user accessible part”.

  The item “update date and time” stores the date and time when the control unit 170 updated the corresponding record in the pressure sensor information table. The item “sensor name” stores the sensor name given to the pressure sensor that can be contacted by the user.

  The item “sensor position” stores the position of the pressure sensor with respect to the user or the pillow apparatus 100. The position of the pressure sensor with respect to the user or the pillow side device 100 includes information on which of the electrode portions 141A and 141B of the pillow side device 100 is in contact with the user, the electrode portions 211A and 211B of the futon side device 200, and the user. It can be determined by the information of the contact state. In addition, the information on the contact state between the electrode units 211A and 211B and the user indicates which of the plurality of electrodes (three in FIG. 2 and FIG. 3) the user has in the electrode units 211A and 211B. Information. For example, in the state of FIG. 2, since the user is in contact with the electrode unit 141B of the pillow side device 100, the control unit 170 determines that the user's neck is on the electrode unit 141B side, On the other hand, the direction in which the user's body exists can be recognized. In addition, since the user is in contact with all of the electrodes of the electrode unit 211A of the futon-side device 200, but is not in contact with all of the electrodes of the electrode unit 211B, the control unit 170 is connected to the electrode unit 211A. It can be determined that the user's back is in contact and the user's feet are in contact with the electrode portion 211 </ b> B, and the user is able to recognize the direction in which the user is sleeping on the mattress 20. Since the controller 170 can recognize the position of the user's head from the direction in which the user's body is present with respect to the pillow 10 and the direction in which the user is sleeping on the mattress 20, the pressure sensor for the user or the pillow-side device 100 can be recognized. The position can be determined. Therefore, in the case of FIG. 2, the control unit 170 sets the position of the pressure sensor 230A to “right front”, the position of the pressure sensor 230B to “right back”, the position of the pressure sensor 230C to “left front”, and the pressure sensor. The position of 230D can be determined as “left back”, the position of the pressure sensor 130A as “right”, and the position of the pressure sensor 130B as “left”.

  Returning to FIG. 5, in the “user contactable part” item, a part of the user's body that can contact each pressure sensor is stored. In this case, since the position of the pressure sensor can be determined as described above, based on the position of the pressure sensor, the control unit 170 determines a part of the user that can contact each pressure sensor. For example, if the position of the pressure sensor is “right front” or “right”, the accessible part is “right hand”, and if the pressure sensor position is “left front” or “left”, the accessible part Is "left hand". Further, if the position of the pressure sensor is “right back” or “left back”, the accessible parts are “right foot” and “left foot”.

  As described above, after step S12 in FIG. 4 is performed, in step S14, the control unit 170 causes the layout information (user or user) of the devices (the television 300, the air conditioner 400, and the lighting fixture 500) to be operated by the user. The positional relationship with respect to the pillow side device 100) is acquired. Note that the control unit 170 acquires the layout information using a method disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-101630.

  FIG. 6A shows an example of layout information of each device. The layout information in FIG. 6A includes items of “update date and time”, “device name”, and “device position”. “Update date and time” stores information on the date and time when the information was updated, and “Device name” and “Device position” contain the name of the device and the layout information of the device (in which direction from the pillow 10 is installed). Information) is stored.

  Next, in step S16 in FIG. 4, the control unit 170 determines the positional relationship between each pressure sensor and each device based on the pressure sensor information table in FIG. 5 and the layout information on each device in FIG. recognize. Specifically, the control unit 170 creates an assignable table as shown in FIG. 6B based on the pressure sensor information table (FIG. 5) and the layout information of each device (FIG. 6A). Generate. The assignable table in FIG. 6B is obtained by adding the item “assignable sensor” to the layout information of each device in FIG.

  When generating the assignable table in FIG. 6B, the control unit 170 refers to FIG. 6A, and based on the fact that the television 300 exists in the back right, the pressure sensor ( 130A, 230A, 230B) are assigned sensors (see FIG. 6B). In addition, referring to FIG. 6A, the controller 170 assigns pressure sensors (130B, 230C, 230D) located on the left side of the user based on the presence of the air conditioner 400 on the left side of the user. (See FIG. 6B). Moreover, with reference to FIG. 6 (A), the control part 170 makes the pressure sensor (130A, 130B) of the pillow side apparatus 100 an assignable sensor based on the presence of the lighting fixture 500 above the user ( (See FIG. 6B).

  Next, in step S18, the control unit 170 assigns the operation of the device to the pressure sensor based on the positional relationship between the pressure sensor and the device. In this case, the control unit 170 generates allocation information as shown in FIG. 7 based on the generated allocatable table. The allocation information in FIG. 7 includes items of “update date and time”, “sensor name”, “user part”, and “assigned device”.

  When generating the allocation information of FIG. 7, the control unit 170 refers to FIG. 6B, allocates the operation of the television 300 to the pressure sensor 230A, allocates the operation of the lighting fixture 500 to the pressure sensor 130B, and controls the pressure sensor 230C. Is assigned to the operation of the air conditioner 400. Here, when there are a plurality of sensors that can be assigned to one device, the control unit 170 selects a pressure sensor to which the operation of the device is assigned based on a predetermined rule. This rule can be set arbitrarily. For example, when there are a plurality of sensors that can be assigned to one device, the user can operate the device on the pressure sensor whose contactable user site is “hand”. A rule of preferential allocation can be set. In addition, as a rule, the rule that the operation of the device is preferentially assigned to the pressure sensor of the futon-side device 200 can be set between the pressure sensor of the futon-side device 200 and the pressure sensor of the pillow-side device 100. Furthermore, it is possible to set a rule that the operation of the device is preferentially assigned to the pressure sensor that can be contacted by the user's dominant hand. Moreover, it is good also as determining the priority at the time of allocation according to the kind etc. of apparatus.

  Returning to FIG. 4, after the process of step S <b> 18 is performed as described above, the process proceeds to step S <b> 20, and the control unit 170 stores the allocation information of FIG. 7 in the memory 160 and ends this process.

  When the allocation information is generated as described above, the content of the allocation information may be announced to the user via a speaker (not shown) or the like. Accordingly, the user can accurately grasp which device is assigned to which pressure sensor.

  The allocation process (FIG. 5) is executed every time human body communication is established, but is not limited to this. For example, the above assignment process may be executed when the electrode part in contact with the user changes (when the user sleeps or the pillow 10 is changed).

(Device operation processing)
Next, an example of device operation processing executed by the control unit 170 of the pillow side device 100 will be described with reference to FIG. It is assumed that device operation allocation information for the pressure sensor is as shown in FIG.

  In the process of FIG. 8, first, in step S <b> 100, the control unit 170 determines whether or not human body communication is established between the pillow side device 100 and the futon side device 200. When this determination is denied, that is, when the user is not sleeping on the mattress 20 and human body communication between the pillow side device 100 and the futon side device 200 is not established, the control unit 170 is The process of step S100 is repeated until human body communication is established. Then, when human body communication is established between the pillow side device 100 and the futon side device 200, the control unit 170 proceeds to step S102. Note that at the stage of shifting to step S102, it is assumed that the user is watching the television 300 while sleeping as shown in FIG.

  If transfering it to step S102, the control part 170 will judge whether the user contacted the pressure sensor. In step S102, even if the user touches the pressure sensor slightly, the determination may be affirmed. For example, only when the user touches the pressure sensor for a predetermined time (several seconds) or more. The judgment may be affirmed. By doing in this way, when a user touches a pressure sensor accidentally, it can prevent that a device malfunctions. If the determination in step S102 is negative, that is, if the user is not in contact with the pressure sensor, the control unit 170 repeats the process in step S102 until the user contacts the pressure sensor. And the control part 170 transfers to step S104 in the step which the user contacted the pressure sensor. It should be noted that at the stage of proceeding to step S104, it is assumed that the user contacts a part of the pressure sensor 230A for a predetermined time.

  If transfering it to step S104, the control part 170 will recognize the apparatus allocated to the pressure sensor which the user contacted. In this case, the control unit 170 recognizes the device that the user is trying to operate (here, the television 300 corresponding to the pressure sensor 230A) based on the assignment information in FIG.

  Next, in step S106, the control unit 170 analyzes how the user contacts the pressure sensor (contact mode) based on the user contact information acquired from the pressure sensor. Here, the analysis method of a contact aspect is demonstrated.

  In the present embodiment, the pressure sensor 230A includes a plurality of (five in FIG. 9) partial pressure sensors 230A1 to 230A5 as shown in FIG. In FIG. 9, it is assumed that the partial pressure sensor 230A1 is located on the near side of the user and the partial pressure sensor 230A5 is located on the far side of the user. In this case, if the user touches the partial pressure sensor in the order of 230A5 → 230A4 →... → 230A1, the control unit 170 analyzes that the user touched the pressure sensor 230A from the back to the front. If the user touches the partial pressure sensor in the order of 230A1 → 230A2 →... → 230A5, the control unit 170 analyzes that the user touched the pressure sensor 230A from the front to the back. If the user touches any of the partial pressure sensors 230A1 to 230A5 for a predetermined time, the control unit 170 analyzes that “the pressure sensor 230A has been pressed for a predetermined time”. Since the other pressure sensors have the same or the same configuration, the same contact mode analysis as described above can be performed.

  In the present embodiment, as described above, the user has been in contact with a part of the pressure sensor 230A (any one of the partial pressure sensors 230A1 to 230A5) for a predetermined time. 230A was pressed for a predetermined time. "

  After the process of step S106 is performed as described above, when the process proceeds to step S108, the control unit 170 recognizes the user's operation based on the user's contact mode with the pressure sensor. Specifically, the control unit 170 recognizes the user's operation based on the operation table shown in FIG. 10 (stored in the memory 160 in FIG. 1). Here, the operation table of FIG. 10 is a table in which the contact state of the user to the pressure sensor and the operation content are associated with each device. In the operation table of FIG. 10, for example, in the case of a television, when the user presses the pressure sensor for a “predetermined time”, the contents that the power is turned on / off, Stores information such as executing volume up when the user sequentially touches the front. In the present embodiment, since the analysis result of step S106 is “the user has pressed the pressure sensor 230A for a predetermined time”, the control unit 170 indicates that the user's operation is an on / off operation of the power of the television. Recognize.

  In the next step S110, the control unit 170 instructs the device recognized in step S104 via the wireless communication unit 120 to execute the operation recognized in step S108. In the present embodiment, since an instruction to turn on / off the power is issued from the control unit 170 to the television 300, the control unit 340 of the television 300 receives the instruction via the communication unit 330. Then, the TV 300 is turned off.

  Note that after the processing up to step S110 is executed, the control unit 170 returns to step S100 and repeatedly executes the processing of FIG.

  In the process of FIG. 8, if the user touches the pressure sensor 230C from the back to the front, the controller 170 controls the device that the user is trying to operate based on the allocation information (FIG. 7). Is recognized as the air conditioner 400, and based on the operation table (FIG. 10), the user recognizes that he / she is going to perform the “upset temperature setting” operation. Thereby, the user can instruct the controller 170 to increase the set temperature of the air conditioner 400. If the user touches a part of the pressure sensor 130B for a predetermined time, the controller 170 determines that the device that the user is trying to operate is the lighting fixture 500 based on the allocation information (FIG. 7). And, based on the operation table (FIG. 10), it is recognized that the user is going to perform a “power on / off” operation. As a result, the user can instruct the controller 170 to turn on / off the lighting fixture 500. In this way, the user can perform a desired operation on a desired device by touching the pressure sensor.

  As described above in detail, according to the present embodiment, the control unit 170 of the pillow-side device 100 recognizes the positional relationship between the pressure sensor and the device that can be contacted by the user, and according to the recognition result, The operation of the device is assigned to a pressure sensor that can be contacted by the user. For this reason, in this embodiment, when the positional relationship between the pressure sensor and the device is changed, the assignment of the operation of the device to the pressure sensor can be appropriately changed. Compared with the case where the is fixed, the user-friendliness can be improved.

  Moreover, in this embodiment, the control part 170 detects a user's position and direction, and selects the pressure sensor which allocates operation of an apparatus according to the detection result. Accordingly, the user can intuitively operate the device by touching the pressure sensor located in the direction in which the device that the user wants to operate exists. For example, the user can touch the pressure sensor 230 </ b> C with the left hand by feeling the airflow from the air conditioner 400 from the left side, and can operate the air conditioner 400 even in a dark environment. Similarly, since the sound of the television 300 flows from the right side, the user can habitually operate the pressure sensor 230A with the right hand.

  In the present embodiment, the control unit 170 assigns an on / off operation of the device and an operation related to the adjustment of the device (volume UP / DOWN, etc.) to the pressure sensor. Thereby, various operation of an apparatus is realizable using one pressure sensor.
