  A technique for outputting diagnostic information to a head mounted display (HMD) using a medical diagnostic device is known. Specific examples of the diagnostic device include an electrocardiograph performing an electrocardiogram examination, an ultrasonic diagnostic apparatus, a magnetic resonance imaging (MRI) apparatus, and an X-ray computed tomography (CT) apparatus. In Patent Document 1, a plurality of HMDs are connected to an information processing apparatus that unifies a wide variety of diagnostic information transmitted from a plurality of diagnostic devices, and each of the plurality of HMDs plays a role in the medical field of the HMD user. A technique for outputting corresponding diagnostic information is disclosed.

JP 2015-19679 A

  By the way, in a scene where a plurality of diagnostic devices are connected to the HMD, an alarm indicating that the diagnostic value is an abnormal value may be output from some of the diagnostic devices. In such a case, the priority of the diagnostic information required by the user may differ depending on the status of the diagnostic information of another diagnostic device and the role of the user in the medical field. However, with the above technique, it is difficult to automatically output diagnostic information according to the priority for each user to the HMD in correspondence with the situation that changes at each time.

  An object of this invention is to provide the information output device which can output-control apparatus information with the priority according to the condition of the field which changes every time at that time.

  An information output device according to the present invention is an information output device that outputs device information output from each of a plurality of measuring devices to an information output unit, and identification information for acquiring identification information for identifying the information output unit Output to the information output unit, the device information acquisition unit that acquires the device information, the device state acquisition unit that acquires the device state that is the state of each of the plurality of measurement devices based on the device information, and First priority setting means for setting a first priority defined in advance for each of the plurality of measuring devices according to the identification information, and the device information acquisition means. Set by the second priority setting means and the first priority setting means for setting the second priority, which is the priority varying according to the device status acquired for each of the plurality of measurement devices. Based on the first priority and the second priority set by the second priority setting means, a third priority that is the priority for each device state according to the identification information is determined. A priority determination unit; and an output control unit that causes the information output unit corresponding to the identification information to output device information corresponding to the device state in accordance with the third priority determined by the priority determination unit. Prepare.

  According to the information output device of the present invention, the first priority setting means sets the first priority, which is the priority of the device information for each of the plurality of measuring devices, according to the identification information. The second priority setting means sets, for each measuring device, a second priority that is a priority corresponding to the device state that is the state of the measuring device. And according to the 1st priority and the 2nd priority, the 3rd priority for every apparatus state according to the identification information which shows each information output part is determined. For this reason, for example, when an alarm indicating that the measurement value is an abnormal value is output from some of the plurality of measurement devices, the device information for each of the plurality of measurement devices according to the identification information Based on the first priority and the second priority according to the device state of the measuring device, necessary information is output to the information output unit of the user according to the identification information. Therefore, the information output apparatus according to the present invention can output and control the device information with the priority according to the on-site situation that changes each time.

  The output control means causes the information output unit to output a recommended image in which an image related to higher-level device information, which is a plurality of device information determined higher in the third priority, can be selected, and the recommended When a selection instruction corresponding to an image is received, device information corresponding to the received selection instruction may be output to the information output unit.

  Depending on the situation of the user, other device information different from the device information corresponding to the third priority may be required. In the information output device, the recommended image related to the higher-level device information determined to be higher in the third priority is output to the information output unit, and the device information corresponding to the selection instruction corresponding to the recommended image is output to the information output unit. For this reason, since the user can select necessary device information, the convenience of the information output device is improved.

  The output control means may output the information amount of device information whose third priority is lower than the higher-level device information while suppressing the information amount to be smaller than the higher-level device information.

  When a large amount of device information is output from the information output unit, depending on the situation of the user, it may not be possible to process all of the information output to the information output unit. The amount of information that can be output by the information output unit is limited. The information output device suppresses and outputs the information amount of the device information having the third priority lower than the upper device information to the information amount smaller than the upper device information, so that the device information suitable for the user's situation is given to the user. Can be provided.

  The information output device includes a device information amount setting unit that sets a device information amount indicating the amount of information of the device information for each of the plurality of measuring devices, and a user processes the device information output from the information output unit. Based on the processing capability setting means for setting the processing capability to be performed according to the identification information, the device information amount set by the device information amount setting means, and the processing capability set by the processing capability setting means. And calculating means for calculating a processing load amount for each of the plurality of measuring devices according to the identification information. The output control means may output the device information to an information output unit corresponding to the identification information according to the third priority and the processing load amount.

  Depending on the information output capability of the information output unit, it may be difficult for the information output device to output device information corresponding to the third priority as it is to the information output unit. In addition, the processing capability of each user for the device information output to the information output unit may be different. Since the information output device calculates the processing load amount according to the device information amount and the user's processing capability, the information output capability of the information output unit and the user's processing are calculated based on the calculated processing load amount according to the third priority. Device information suitable for performance can be output.

  The output control means may output the pieces of device information having the same third priority at different output timings in any order according to the device information.

  For example, when a plurality of pieces of audio information are included in a plurality of pieces of device information, even if a plurality of pieces of device information are output at a time from the information output unit, the user may not be able to grasp necessary information. Since the output control means can output device information having the same third priority at different output timings according to the device information, the convenience of the information output device is improved.

  The information output device includes an update reception unit that receives an update request for updating at least one of the first priority and the second priority, and the update request received by the update reception unit has specific characteristics. An update determination means for determining whether the information is based on the identification information, and the update determination means when the update request is determined to be identification information having the specific characteristic in response to the update request. The first priority and the second priority are updated, and when it is determined that the update request is not identification information having the specific characteristic, the first priority and the second priority according to the update request Update means that does not update.

  In this case, the first priority is updated only when the update request is based on identification information having specific characteristics. When the user of the information output unit corresponding to the identification information having specific characteristics determines that the first priority and the second priority should be updated, the device information of the third priority corresponding to the update request is information Since it is output to the output unit, other users can easily grasp necessary information.

  The identification information acquisition unit refers to a transition order storage unit that stores a transition order in which the specific characteristic transitions in a plurality of pieces of identification information corresponding to the plurality of information output units, and sets the identification information having the highest transition order. The characteristic of the corresponding information output unit may be set to the specific characteristic.

  For example, the user of the information output unit corresponding to identification information having specific characteristics may leave the place. Even in such a case, since specific characteristics are changed in the order of transition in a plurality of pieces of identification information, device information corresponding to the situation at the site where the information output device is used is output from the information output unit.

  The information output apparatus may include an update prohibiting unit that prohibits a part or all of the update in at least one of the first priority and the second priority by the update unit.

  In this case, for example, the information output device can prevent the update unit from updating the area that should not be updated, among the first priority and the second priority.

The HD 20 can irradiate image light backward. The image light is incident on a light receiving object (for example, the left eye of the user wearing the HMD 10). The HD 20 is detachably connected to the CB 30 via the harness 7. The HD 20 includes a housing 20A.

  The housing 20A includes a resin half mirror 4 on the left end side. The half mirror 4 is disposed in front of the user's left eye when the HMD 10 is mounted on the user's head. Inside the housing 20A, an image display unit 22 and a lens unit (not shown) are arranged in order from the right side to the left side. The image display unit 22 is a liquid crystal element. The image display unit 22 displays an image based on the video signal received from the CB 30 via the harness 7. The display surface of the image display unit 22 faces leftward. Video light indicating the video displayed on the image display unit 22 enters the lens unit from the right side and exits toward the half mirror 4 from the left side. The half mirror 4 reflects the image light emitted from the lens unit backward. In a state where the HMD 10 is worn by the user, the image light is incident on the eyeball of the user's left eye. The half mirror 4 transmits light from the real image of the outside world toward the left eye of the user. The HMD 10 allows the user to visually recognize a scene in which a video image displayed on the image display unit 22 is superimposed on a real image (for example, an external scenery or the like) within the visual field range of the user.

  The image display unit 22 may be a liquid crystal display, an organic EL (Organic Electro-luminescence) display, or the like. The image display unit 22 may be a retinal scanning type projection device that projects light two-dimensionally scanned onto a user's retina. The half mirror 4 may be made of glass. Instead of the half mirror 4, an optical path deflecting member that deflects the optical path by an action such as refraction, total internal reflection, or diffraction, such as a prism or a diffraction grating, may be used. Instead of the half mirror 4, a total reflection mirror may be used.

  The wearing tool 8 is configured to hold the HD 20 on the user's head. The mounting tool 8 is formed of a metal material such as a flexible resin or stainless steel, for example. The mounting tool 8 has a first portion 8A and a pair of second portions 8B. Each of the first portion 8A and the pair of second portions 8B is a curved and elongated plate-like member. The wearing tool 8 is attached to the user's head with the first portion 8A placed along the user's forehead and a pair of second portions 8B along the right and left heads of the user.

  The connection tool 9 is a structure for connecting the mounting tool 8 and the HD 20. The connection tool 9 is a slightly curved rod-like member. The upper end portion of the connection tool 9 is connected to the mounting tool 8. The lower end portion of the connection tool 9 is connected to the HD 20. The connection tool 9 holds the HD 20 at a position separated from the mounting tool 8. The connecting tool 9 can place the half mirror 4 of the housing 20A in front of the user's left eye in a state where the mounting tool 8 is mounted on the user. In this case, the user can visually recognize the image displayed on the image display unit 22 through the half mirror 4.

  The CB 30 controls the HD 20. The CB 30 is connected to the HD 20 via the harness 7. Note that the CB 30 and the HD 20 may perform wireless communication via wireless regardless of the harness 7. The CB 30 is attached to a position different from the HD 20 (for example, a user's waist belt, arm, etc.). However, the CB 30 may be configured integrally with the HD 20 or the wearing tool 8. The CB 30 includes an operation unit 37 including a power switch and operation buttons (not shown). Various settings in the HD 20, various operations during use, power on / off operations, and the like are input to the operation unit 37.

  Next, the electrical configuration of the HMD 10 will be described. First, the electrical configuration of the CB 30 will be described. The CB 30 includes a CPU 31 that controls the entire CB 30. The CPU 31 is electrically connected to the RAM 32, the flash memory 33, the input unit 34, the wireless communication unit 36, the operation unit 37, and the connection controller 35. The RAM 32 temporarily stores various data such as calculation results obtained by calculation processing by the CPU 31.

  The flash memory 33 is a nonvolatile storage device. The flash memory 33 stores the OS. In addition, the flash memory 33 stores various programs executed by the CPU 31 including the main program, flags used by the various programs, initial values of data, and the like. The main program is a program for controlling various operations of the HMD 10, and is a multitasking program that executes various programs by parallel processing. Various programs are executed on the OS. Various programs and the OS are stored in the flash memory 33 when the HMD 10 is shipped.

  The flash memory 33 stores an information output program for the CPU 31 to execute an information output process (see FIGS. 4 and 5) described later, and a table update program for the CPU 31 to execute a table update process (see FIG. 16). To do. The information output program and the table update program are included in various programs executed by the CPU 31 in accordance with the main program. The flash memory 33 includes a device information table 60 (see FIG. 2), a user information table 70 (see FIG. 3), a first priority table 80 (see FIG. 6), and a second priority table 90 (see FIG. 2). 7) and the third priority table 110 (see FIG. 8).

  Further, the HMD 10 may download and install various programs and an OS from a program download server via wireless communication. For example, the various programs and the OS may be transmitted from the server to the HMD 10 as a computer-readable temporary storage medium (for example, a transmission signal). The flash memory 33 is an example of a non-temporary storage medium. The non-temporary storage medium may be any storage medium that can store information regardless of the period in which the information is stored. The non-transitory storage medium may not include a temporary storage medium (for example, a signal to be transmitted). The storage device in the present embodiment is the flash memory 33, but the storage device is another non-transitory storage medium that can hold data regardless of the length of time for storing information, for example, ROM, RAM, etc. It may be configured.

  The input unit 34 includes one or a plurality of interface input terminals conforming to a predetermined standard (for example, Universal Serial Bus (USB)), and functions as an input port for connecting the CB 30 and an external device. In the present embodiment, a plurality of measuring devices 50 of measuring devices 1 to N can be connected to the input unit 34. The measuring device 50 is various devices used in the medical field. The measuring device 50 includes, for example, an electrocardiograph that performs an electrocardiogram examination, an electroencephalograph that measures an electroencephalogram, an ultrasonic diagnostic apparatus, an MRI apparatus, an X-ray CT apparatus, a personal computer (PC), and the like, and displays an image of a medical chart. An information processing apparatus that outputs the information. The input unit 34 acquires information input from the connected measuring device 50. The information input from the measuring device 50 is information corresponding to, for example, an image or sound indicating the content measured or imaged by the measuring device 50, and is also referred to as “device information” below.

  The wireless communication unit 36 is a controller for connecting to the network 11 by wireless communication and performing wireless communication with other HMDs 10 connected to the network 11. The operation unit 37 performs input / output of an input signal or the like corresponding to an operation by the user. The connection controller 35 is electrically connected to the connection controller 21 of the HD 20 via the harness 7 and performs wired communication.

  Next, the electrical configuration of the HD 20 will be described. The HD 20 includes a connection controller 21, an image display unit 22, a microphone 25, and a speaker 26. The connection controller 21, the image display unit 22, the microphone 25, and the speaker 26 are electrically connected. The connection controller 21 is electrically connected to the connection controller 35 of the CB 30 via the harness 7 and performs wired communication. The microphone 25 converts an analog sound input from the outside of the housing 20A (for example, a user's mouth) into digital sound data, and outputs the sound data. The speaker 26 converts sound data received via the connection controller 21 from digital to analog sound, and outputs the sound to the outside of the housing 20A (for example, a user's ear). The microphone 25 and the speaker 26 are not limited to ordinary air-conducting microphones and speakers, and may be bone conduction type. As described above, the image display unit 22 displays an image based on the video signal.

  A procedure when the user of the HMD 10 uses the information output system 100 will be described. In the present embodiment, it is assumed that the information output system 100 includes three HMDs 10 of HMDs 10A, 10B, and 10C. The medical site in the present embodiment is assumed to be a scene of surgery. Assume that the roles of the users of the HMD 10 in the medical field are, for example, a surgeon, a first assistant, and an anesthesiologist. The role indicates the participation mode of each user in the medical field. Of the roles, it is assumed that the surgeon is given a specific authority to supervise the medical field in advance.

  First, the user of the HMD 10 connects the measuring device 50 used in the medical field to the input unit 34 of the CB 30. In the present embodiment, it is assumed that the measuring devices 1 to 3 among the measuring devices 50 are connected to the input unit 34. In the present embodiment, for example, the measuring device 1 is an ultrasonic diagnostic apparatus, the measuring device 2 is an electroencephalograph, and the measuring device 3 is a heart rate monitor. The measuring devices 1 to 3 may be connected only to a part of the HMDs 10 included in the information output system 100 such as the HMD 10A, or connected to each of all the HMDs 10 included in the information output system 100. Also good. Thereafter, the user of the HMD 10 establishes wireless communication between the HMDs 10A, 10B, and 10C. Various types of information transmitted and received between the HMDs 10A, 10B, and 10C by wireless communication are referred to as device information. The device information includes, for example, information (for example, a user ID or device ID described later) that identifies which HMD 10 the transmission source HMD 10 is in the header area. Note that, by establishing this wireless communication, sound such as sound collected by the microphone 25 of the other HD 20 is output from the speaker 26. Thereby, the user can have a conversation with another user via the microphone 25 and the speaker 26.

  The device information table 60 will be described with reference to FIG. The device information table 60 stores information related to the device information pattern for each measuring device 50. As illustrated in FIG. 2, the device information table 60 stores a measurement device ID, a device pattern, a first threshold value, and a second threshold value in association with each other. The measurement device ID is an ID given by the CPU 31 in order to identify which of the measurement devices 1 to N is the measurement device 50. In the present embodiment, each of the measuring devices 1 to 3 corresponds to a measuring device ID.

  The device pattern is information that can identify which measuring device 50 is the device information input to the CPU 31 via the input unit 34. In the present embodiment, the device pattern is information indicating the pattern of the image signal indicated by the device image input from each of the plurality of measuring devices 50. The device pattern is information on a template image for determining which measurement device 50 is the device image corresponding to the device information input to the CB 30 via the input unit 34 by pattern matching. Also good. Further, the device pattern may be a pattern obtained by extracting a unique image signal pattern for each measuring device 50 included in the device information. In addition, the device pattern may be various information that each of the measuring devices 50 outputs as header information of the device information.

  The first threshold value and the second threshold value indicate reference values for the CPU 31 to determine a device state that is a state for each measuring device 50. Specifically, the CPU 31 determines that the device state is any of the three states A, B, and C according to the measurement value measured by the measurement device 50, the measurement result indicated by the device image of the measurement device 50, and the like. It is determined whether it is. The state A is a state in which the necessity of paying attention of the user to the device information is the lowest among the three levels, such as the patient's condition indicated by the device information is relatively good. The state B is a state where attention should be paid to the device information rather than the state A, for example, the patient's condition is worse than the state A. The state C is a state in which the user needs to pay the most attention to the device information among the three stages, such as the patient's condition is further deteriorated than the state B. When the device information indicates information lower than the first threshold, the CPU 31 determines that the device state is state A. When the device information indicates information that is greater than or equal to the first threshold value and less than the second threshold value, the CPU 31 determines that the device state is state B. When the device information indicates information equal to or greater than the second threshold, the CPU 31 determines that the device state is state C.

  The user information table 70 will be described with reference to FIG. As shown in FIG. 3, the user information table 70 stores a user ID, a device ID, role information, and a characteristic flag in association with each other in the order of “NO.”. The user ID is identification information for identifying a user who uses the information output system 100. The device ID is identification information for identifying the HMD 10 used by the user identified by the corresponding user ID. The role information indicates any one of “surgeon”, “first assistant”, and “anesthesiologist”, which is the role of each user identified by the corresponding user ID.

  The characteristic flag is “1” stored to be “ON”, “0” is stored to be “OFF”, and a characteristic flag corresponding to a role to which a specific authority is granted is ON. Is done. The user information table 70 is stored in the uppermost column of the user information table 70 at the start of execution of the information output process. The characteristic flag corresponding to 1 is set to be “ON”. For example, a part of the user may leave the medical site while the information output process proceeds. In this case, the user corresponding to the user ID “U0001” to which the specific authority is given terminates the use of the HMD 10 corresponding to the device ID “HMD10A” and leaves the wireless communication between the HMDs 10A, 10B, and 10C. There are things to do. In such a case, the CPU 31 sets the characteristic flag corresponding to the next largest “NO.” To “ON” with respect to “NO.” Corresponding to the user ID for which the specific flag was previously set to “ON”. ", And the characteristic flag previously set to" ON "is set to" OFF ". Thus, “NO.” In the user information table 70 indicates the transition order in which the characteristic flag transitions in the user information table 70.

  In the present embodiment, the sound information transmitted to the HD 26 speaker 26 of the other HMD 10 via the other HMD 10 microphone 25 has a priority in the order of “NO.” In the user information table 70. Is provided. When a plurality of pieces of sound information are simultaneously received from a plurality of other HMDs 10, the CPU 31 obtains sound information transmitted from the HMD 10 corresponding to the device ID having a higher order of “NO.” In the order of “NO.”. Before the sound information transmitted from the HMD 10 corresponding to the low device ID, the speaker 26 outputs the sound information. When a plurality of sounds are output from the speaker 26, it may be difficult to distinguish each sound. In particular, it is not preferable in the medical field to miss a sound related to a user ID to which a specific authority is given. The CPU 31 reduces the output of sound information transmitted from other HMDs 10 in accordance with the order of “NO.”, Thereby reducing the user's oversight of sounds related to sound information with a higher order of “NO.” it can.

  The information output process will be described with reference to FIGS. 4 and 5. The HMD 10 is shipped with the information output program stored in the flash memory 33 in advance as described above. The information output program is a program executed by the CPU 31 in the CB 30 of the HMD 10. The CPU 31 that has executed the information output program determines a priority for each device state according to the user ID, and performs processing for causing the HMD 10 to display a device image based on the device information based on the determined priority. In the following description, it is assumed that the CPU 31 of the HMD 10A is executing an information output program.

  A process performed by the CPU 31 along with the execution of the information output process will be described. When the user operates the power switch in the operation unit 37 of the CB 30, the CPU 31 performs an operation associated with a predetermined initial setting process (not shown) at the time of activation. The CPU 31 initializes flags and data stored in the RAM 32 and writes initial values of the flags and data stored in the flash memory 33 to the RAM 32.

  When the initial setting process is completed, the CPU 31 starts the information output process. As shown in FIG. 4, when the information output process is started, the CPU 31 is established between the HMDs 10A, 10B, and 10C. The device information of the other HMD 10 is acquired through the wireless communication. The CPU 31 refers to the user information table 70 and acquires the user ID corresponding to the transmission source HMD 10 based on the information specifying the transmission source HMD 10 included in the header area of the acquired device information (S11). Further, the CPU 31 acquires a user ID corresponding to its own HMD 10 based on the information included in the header area of the device information transmitted to the other HMD 10 (S11). By this process, the CPU 31 can grasp which HMD 10 is connected to the network 11.

  The CPU 31 refers to the first priority table 80 stored in the flash memory 33 (S12). The first priority table 80 will be described with reference to FIG. The first priority table 80 defines the priority with which device information is output to the HMD 10 using a predetermined first priority index for each measurement device ID. When the user uses the HMD 10, the device information output from the measuring device 50 connected to the HMD 10 is required to the same extent, and some device information is given priority over other device information. It may be necessary. The first priority index is an index indicating the priority of such device information. The first priority index may be derived by quantifying the priority of the device information by a prior experiment or the like. Here, when a plurality of users use the respective HMDs 10, even in the same medical field, device information required by the users may differ among users depending on their roles. The first priority table 80 sets a first priority index for each measuring device ID for each user ID. For this reason, HMD10 can set the priority of the apparatus information according to a user's role. Such a priority for each measuring device ID defined for each user ID is hereinafter referred to as a first priority.

  As illustrated in FIG. 6, the first priority indexes of the measuring devices 1 to 3 associated with the user ID “U0001” are all “30”. For example, such a first priority is set when the role of the user is a role that should pay attention to any device information output from the measuring devices 1 to 3 to the same extent. On the other hand, the first priority indexes of the measuring devices 1 to 3 associated with the user IDs “U0002” and “U0003” are assigned to different values according to their roles.

  The “update prohibition flag” field provided in the first priority table 80 is provided to set whether or not to prohibit the update of the first priority in a table update process (see FIG. 17) described later. Yes. In FIG. 6, the update prohibition flags corresponding to the user IDs “U0001” and “U0002” store “0” and “OFF”. The update prohibition flag corresponding to the user ID “U0003” stores “1” and is “ON”. In the table update process, it is determined that the update is prohibited for the data string whose update prohibition flag is “ON”, and the update is not prohibited for the data string whose update prohibition flag is “OFF”.

  Returning to the description of FIG. CPU31 acquires the information which shows the 1st priority for every measuring device ID corresponding to each user ID in the 1st priority table 80 (S13). The CPU 31 acquires device information from each of the measuring devices 50 connected to the HMD 10 (S15). In this process, the CPU 31 first determines whether device information is input to the input terminal with the smallest number among the plurality of input terminals provided in the input unit 34. When device information is input, the CPU 31 acquires the input device information. Hereinafter, among the plurality of input terminals provided in the input unit 34, the CPU 31 is configured to input terminals from the input terminal with the next highest number after the lowest number to the input terminal with the highest number. The determination as to whether information is input and the acquisition of device information are repeatedly executed when device information is input.

  The CPU 31 refers to the device information table 60 stored in the flash memory 33 (S16). CPU31 acquires measurement apparatus ID and apparatus information about each of the apparatus information acquired by the process of S15 (S18). In this process, the CPU 31 compares the pattern indicated by the acquired device information with a plurality of device patterns stored in the device information table 60, and the pattern indicated by the acquired device information is one of the plurality of device patterns. It is judged whether it matches. If any of the plurality of device patterns matches the pattern indicated by the acquired device information, the CPU 31 specifies the measurement device ID associated with the device pattern determined to match in the device information table 60. That is, the measurement device ID of the measurement device 50 that has output the device information to be determined is specified. The CPU 31 determines whether the device state of the device information to be determined is any of the states A to C based on the first threshold value and the second threshold value associated with the measurement device ID specified in the device information table 60. . For example, in the ultrasonic image 221 that is a device image related to the measurement device 1 shown in FIG. In the waveform image 222 that is a device image related to the measurement device 2 shown in FIG. 14, the waveform based on the measurement value of the measurement device 2 exceeds the horizontal axis with the horizontal axis indicated by the lower side of the frame line surrounding the waveform image 222 as a threshold value. The device state is determined to the extent that it is drawn as such. In the electrocardiogram image that is a device image related to the measuring device 3 shown in FIG. 14, the device state is determined using a predetermined value of the heart rate as a threshold value. If the device information is audio information, the device state is determined using a predetermined volume / frequency indicated by the audio information as a threshold value. For example, for device information indicated by numerical values such as heart rate and blood pressure value, the numerical value itself or a value indicated by a value obtained by multiplying the numerical value by a predetermined coefficient may be treated as the device state. By performing these processes for the other device information acquired in S15, the measurement device ID and the device state corresponding to each of the device information acquired in S15 are acquired. The CPU 31 stores the measurement device ID and the device state corresponding to the measurement device ID in the RAM 32.

  The CPU 31 refers to the second priority table 90 stored in the flash memory 33 (S19). The second priority table 90 will be described with reference to FIG. The second priority table 90 defines the priority of the device information according to the device state using a predetermined second priority index for each measuring device ID. When the user uses the HMD 10, even the same measuring device 50 may differ in the degree of needing device information depending on the device state. The second priority index is not a single value fixed for each measuring device 50, but a value that varies depending on the device state for each measuring device 50, and is an index indicating the priority of the device information according to the device state It is. The second priority index may be derived by quantifying the priority of the device information by a prior experiment or the like. In the present embodiment, regardless of the measuring device ID, the second priority index in state A is “30”, the second priority index in state B is “50”, and the second priority index in state C is “80”. Are defined in the second priority table 90. For example, the degree of necessity for each piece of device information may differ between the measuring devices 50 depending on the device state. In this case, a different second priority index may be set for each measuring device ID for each device state. Such a priority for each device state defined for each measuring device ID is hereinafter referred to as a second priority.

  Returning to the description of FIG. CPU31 acquires the 2nd priority for every measurement apparatus ID according to apparatus state based on measurement apparatus ID acquired by the process of S18, and apparatus state corresponding to measurement apparatus ID (S21). In the present embodiment, in the process of S18, the “measurement device ID” “measurement device 1” has “state B”, the measurement device ID “measurement device 2” has “state C”, and the measurement device ID “measurement device 3” has “ It is assumed that “state C” is acquired correspondingly. In this case, “50” shown in the box 91 assuming that the device state of the “measuring device 1” is “state B”, and “80” shown in the box 92 indicating that the device state of the “measuring device 2” is “state C”. "30" shown in the box 93 is acquired as the second priority, assuming that the device state of "measuring device 3" is "state A".

  Based on the first priority acquired in the process of S13 and the second priority acquired in the process of S21, the CPU 31 has a priority corresponding to each of the user ID, the measurement apparatus ID, and the apparatus state. The priority is calculated (S22). In this process, the CPU 31 generates a third priority table 110 as shown in FIG. 8, for example, in the flash memory 33, and calculates the third priority. The third priority table 110 associates each user ID with each measurement device ID. First, the CPU 31 registers, in the third priority table 110, the first priority (box 801 in FIG. 8) for each measurement device ID corresponding to each user ID acquired in the process of S13. Next, the CPU 31 adds the second priority (box 901 in FIG. 8) for each measurement device ID, which is acquired in the process of S21, according to the device state, to the first priority. At this time, since the device state of “measurement device 1” is “state B” in the second priority table 90, the second priority “50” is set to “measurement device 1” in the third priority table 110. Is added. Similarly, since the device state of “measurement device 2” in the second priority table 90 is “state C”, the second priority “80” is set to “measurement device 2” in the third priority table 110. Is added. Since the device state of “Measurement device 3” is “State A” in the second priority table 90, the second priority “30” is added to “Measurement device 1” in the third priority table 110. The Thereby, the third priority corresponding to each of the user ID, the measuring device ID, and the device state is calculated. In this way, the CPU 31 does not calculate the priority of the device information based on only the first priority or the second priority, but the status for each user ID and the status of the device status for each measurement device ID. The third priority can be calculated as the priority of the device information corresponding to each of the above.

  In FIG. 8, the values shown in square brackets ("") indicate the order of the third priority in descending order for each user ID. For example, for the user ID “U0001”, the value of the third priority is “80” for “Measurement device 1”, “110” for “Measurement device 2”, and “60” for “Measurement device 3”. Therefore, the order of the third priority in “U0001” is “measurement device 2” is “1”, “measurement device 1” is “2”, and “measurement device 3” is “3”.

  Next, as shown in FIG. 5, the CPU 31 refers to the device information amount table 120 stored in the flash memory 33 (S31). The device information amount table 120 will be described with reference to FIG. The device information amount table 120 defines a device information amount that is each information amount of device information output from the measuring device 50 using a predetermined device information amount index for each measuring device ID. The device information amount is, for example, the amount of information included in a device image corresponding to device information. The device information amount is, for example, the amount of information included in the sound information corresponding to the device information. The device information amount index may be derived by quantifying the device information amount of the device information by a prior experiment or the like. In the present embodiment, the measurement device 1 corresponds to an ultrasonic diagnostic apparatus, the measurement device 2 corresponds to an electroencephalograph, and the measurement device 3 corresponds to a heart rate monitor. In the device information table 120, the device information amount corresponding to each measurement device 50 is used. Different values are defined as the index.

  Returning to the description of FIG. The CPU 31 acquires the device information amount for each measurement device ID from the referenced device information amount table 120 (S32). The CPU 31 refers to the user processing capacity table 130 stored in the flash memory 33 (S33).

  The user processing capacity table 130 will be described with reference to FIG. The user processing capability table 130 indicates the capability of the user of the HMD 10 regarding, for example, visually recognizing a device image based on device information and making a determination according to a medical site, that is, processing device information. Each is defined using a predetermined processing capability index. In the present embodiment, the processing capability index indicates the ability of the user to process a predetermined amount of device information per predetermined time. The processing capability of device information may differ from user to user depending on the weakness of processing device information and the experience of the user. In addition, even for the same user, the processing capability may differ depending on which device 50 has the device information. In addition, user processing for device information of the same measuring device 50 may differ depending on the role of the user. For example, it is conceivable that the surgeon and the anesthesiologist make judgments on the device image from different viewpoints for each role for the same electroencephalograph device image, so the processing capability for the same device information is different for each role. May be different. For this reason, the user processing capability table 130 sets a processing capability index for each measuring device ID for each user ID. Considering these various factors, and through a prior experiment or the like, the processing capability index may be derived by quantifying the processing capability of the device information. Such processing capability for each measurement device ID defined for each user ID is hereinafter referred to as user processing capability.

  Returning to the description of FIG. The CPU 31 acquires the user processing capability for each measuring device ID defined for each user ID from the referenced user processing capability table 130 (S35). The CPU 31 calculates a processing load amount corresponding to the user ID and the measurement device ID based on the device information amount acquired in the process of S32 and the user processing capability acquired in the process of S35 (S36). The processing load amount is obtained by quantifying a load necessary when processing each piece of device information with each user processing capability.

  In this processing, the CPU 31 generates a processing load amount table 140 as shown in FIG. 11 in the flash memory 33, for example, and calculates the processing load amount. The processing load amount table 140 associates each user ID with each measurement device ID. In the present embodiment, the processing load amount is calculated as a result of dividing the device information amount included in each device information by each user processing capability. First, the CPU 31 registers the information amount (box 1201 in FIG. 11) for each measuring device ID acquired in the process of S32 in the processing load amount table 140. Next, the CPU 31 divides each information amount registered in the processing load amount table 140 by the user processing capability (box 1301 in FIG. 11) for each measuring device ID corresponding to each user ID acquired in the processing of S35. Thereby, the processing load amount for each measuring device ID corresponding to each user ID is calculated.

  Next, as shown in FIG. 5, the CPU 31 refers to the simultaneous processing amount table 150 stored in the flash memory 33 (S39). The simultaneous processing amount table 150 will be described with reference to FIG. Some users, for example, are good at viewing and processing a plurality of device images based on a plurality of device information at the same time, and are not good at viewing a plurality of device images at the same time. Some people are good at processing one by one. The simultaneous processing amount table 150 defines the amount of information that each user can process per predetermined time using a predetermined simultaneous processing amount index according to the processing characteristics of the user's device information. For users who are good at processing a plurality of device images at the same time, the simultaneous processing amount index of the simultaneous processing amount table 150 is defined to be large. In the present embodiment, as shown in FIG. 12, “6” is assigned to the user ID “U0001”, “7” is assigned to the user ID “U0002”, and “5” is assigned to the user ID “U0003”. Is defined in the simultaneous processing amount table 150.

  Next, as illustrated in FIG. 5, the CPU 31 acquires the simultaneous processing amount for each user ID from the referenced simultaneous processing amount table 150 (S <b> 39). The CPU 31 specifies the information amount of the device information in a range not exceeding the simultaneous processing amount acquired in the processing of S39 according to the third priority calculated in the processing of S22 and the processing load amount calculated in the processing of S36. (S41).

  This process will be specifically described. The value stored in the processing load amount table 140 shown in the upper part of FIG. 13 indicates the processing load amount corresponding to the user ID and the measurement device ID, which is the calculation result calculated in the processing of S36. In the processing load amount table 140 shown in the upper part of FIG. 13, the value shown in square brackets (“”) is the third priority calculated in the process of S22. For each user ID, the CPU 31 adds the processing load amount for each measuring device ID in descending order of the third priority within a range that does not exceed the value indicated by the simultaneous processing amount acquired in the processing of S39. Then, the CPU 31 specifies the measurement device ID that can add the processing load amount index within a range not exceeding the value indicated by the simultaneous processing amount.

  In the upper part of FIG. 13, for the user ID “U0001”, the processing load amount “2” of the measuring device 2 whose third priority is “1” and the processing load of the measuring device 1 whose third priority is “2” Each of the processing load amounts “1” of the measuring device 3 having the amount “1.5” and the third priority “3” is shown in the processing load amount table 140. The result of adding these processing load amounts in the order of the third priority is “2 + 1.5 + 1 = 4.5”. This result does not exceed “6”, which is the simultaneous processing amount of the user ID “U0001”, acquired in the process of S39. For this reason, CPU31 makes all the measuring devices 1-3 the specific object in the process of S41.

  For the user ID “U0002”, the processing load “1” of the measuring device 3 whose third priority is “1” and the processing load “4” of the measuring device 2 whose third priority is “2”. At the time point when and are added, the addition result does not exceed “7”, which is the simultaneous processing amount of the user ID “U0002”. However, the processing load amount “1” of the measuring device 3 with the third priority “1”, the processing load amount “4” of the measuring device 2 with the third priority “2”, and the third priority. “8” that is the addition result of adding the processing load amount “3” of the measuring device 1 with “3” exceeds “7” that is the simultaneous processing amount of the user ID “U0002”. Therefore, the CPU 31 sets the measuring device 3 and the measuring device 2 corresponding to the processing load amount within the range not exceeding the simultaneous processing amount of the user ID “U0002” as specific targets in the processing of S41. Similarly, for the user ID “U0003”, the processing load amount of the measuring device 2 having the third priority “1” is “5”. Therefore, the CPU 31 sets only the measuring device 2 corresponding to the processing load amount in a range not exceeding “5” which is the simultaneous processing amount of the user ID “U0003” as a specific target in the processing of S41.

  Next, as illustrated in FIG. 5, the CPU 31 outputs an instruction to output device information to the HD 20 via the connection controller 35 according to the content specified in the process of S <b> 41 (S <b> 42). In this process, in the present embodiment, the CPU 31 determines that the device information corresponding to the measurement device ID that is the specific target in the process of S41 is to be output to the HD 20. That is, as shown in the processing load amount table 140 in the lower part of FIG. 13, the CPU 31 determines that all the device information of the measuring devices 1 to 3 is output to the HD 20 for the user ID “U0001”. For the user ID “U0002”, the CPU 31 determines that the device information of the measuring device 3 and the measuring device 2 is output to the HD 20. For the user ID “U0003”, the CPU 31 determines that only the device information of the measuring device 2 is output to the HD 20.

  In the present embodiment, when a device image based on a plurality of device information is output to the image display unit 22 in the process of S42, the CPU 31 converts a device image having a higher third priority to a device having a lower third priority. Display using a larger area than the image. When the output of the device image based on the device information corresponding to the measuring devices 1 to 3 is determined as shown in the processing load amount table 140 in the lower part of FIG. 13, the CPU 31 uses the user ID “ Each device image is displayed on the image display unit 22 of the HMD 10 of “U0001”. Here, the CPU 31 causes the image display unit 22 to display the waveform image 222, which is the device image related to the measuring device 2 having the highest third priority, using a larger area than the other device images. The CPU 31 causes the image display unit 22 to display an ultrasonic image 221 that is a device image related to the measuring device 1 having the second highest priority using a smaller area than the waveform image 222. The CPU 31 causes the image display unit 22 to display a heart rate image 223 that is a device image related to the measurement device 3 having the lowest third priority, using an area smaller than the ultrasonic image 221. By doing in this way, CPU31 can show a user the apparatus image regarding the apparatus information with higher 3rd priority more easily to a user.

  Here, in the process of S42, the CPU 31 may send an instruction to the image display unit 22 to display the selected image 225 (see the upper part of FIG. 15). In this case, the CPU 31 may cause the image display unit 22 to display a device image corresponding to an input of a predetermined instruction associated with the selection image 225 being displayed on the image display unit 22.

  As shown in FIG. 15, the selection image 225 is an image for allowing the user to select desired device information. Here, an example is shown in which the selected image 225 is displayed on the image display unit 22 of the HMD 10 corresponding to the user ID “U0001” whose third priority is the order of the measuring device 2, the measuring device 1, and the measuring device 3. Explained. The selection image 225 includes a first image 225A, a second image 225B, and a third image 225C. The first image 225A is an image for selecting the waveform image 222 of the measuring device 2 having the highest third priority. The second image 225B is an image for selecting the ultrasound image 221 of the measuring device 1 having the second highest priority. The third image 225C is an image for selecting the heart rate image 223 of the measuring device 3 having the lowest third priority. The first image 225A, the second image 225B, and the third image 225C are arranged side by side from the front side to the rear side of the image display unit 22 in descending order of the third priority. Can be shown.

  When the CPU 31 displays the selected image 225 on the image display unit 22, the CPU 31 displays one of the first image 225 </ b> A, the second image 225 </ b> B, and the third image 225 </ b> C through the operation of the operation button of the operation unit 37. Wait for the selection instructions to be entered. In the upper part of FIG. 15, the first image 225 </ b> A is indicated by a double frame, indicating that an instruction to select the first image 225 </ b> A is input. Thereafter, the CPU 31 displays a waveform image 222 corresponding to the first image 225A in response to an input of an instruction to select the first image 225A (see the lower part of FIG. 15). The CPU 31 can cause the user to display a device image corresponding to the third priority on the image display unit 22 by displaying the selected image 225 on the image display unit 22. Further, depending on the current situation of the medical site, the user may want to view device information different from the device information determined to be higher in the third priority. The CPU 31 can visually indicate to the user, together with the third priority, which device information is determined to be higher in the third priority by the selected image 225. For this reason, since the user can arbitrarily select the device information that the user wants to view while grasping the third priority from the selection image 225, the device image corresponding to the third priority is uniformly displayed on the image display unit 22. The convenience of the HMD 10 is improved compared to the display.

  As shown in the upper part of FIG. 15, in the selected image 225, the third image 225C corresponding to the heart rate image 223 having the lowest third priority is shown with higher brightness than the first image 225A and the second image 225B. It is. For this reason, the third image 225C is displayed in a manner that is less visible than the first image 225A and the second image 225B. That is, the image display unit 22 is configured such that the third image 225 </ b> C related to the device information of the measuring device 3 has a smaller amount of information than the first image 225 </ b> A and the second image 225 </ b> B related to the device information of the measuring device 1 and the measuring device 2. Is displayed. The CPU 31 displays the third image 225C in such a display manner that suppresses the amount of information for the user, so that the device image corresponding to the third image 225C among the three types of device images shown in the selected image 225 is displayed. It can be visually shown to the user that the third priority is the lowest.

  Further, when the device image is displayed by the processing of S42 on the image display unit 22 of the HMD 10 corresponding to the user ID “U0002” whose third priority is the measuring device 3, the measuring device 2, and the measuring device 1 in this order. Will be described with reference to FIG. In this case, as shown in the lower part of FIG. 13, the CPU 31 determines to output the device information of the measuring device 3 and the measuring device 2 to the HD 20 by the process of S41. In such a case, the CPU 31 causes the image display unit 22 to display the heart rate image 223 related to the measuring device 3 and the waveform image 222 related to the measuring device 2 determined to be output in the process of S41 (see the upper part of FIG. 16). . The ultrasonic image 221 relating to the measuring device 1 is not displayed together with the heart rate image 223 and the waveform image 222. As described above, the CPU 31 suppresses the output of the device information output from the measuring device 1 having the lowest third priority with respect to the device information having the higher third priority, thereby allowing the user to perform simultaneous processing. A device image based on device information having an information amount corresponding to the amount can be provided to the user.

  In this case, the CPU 31 may cause the device information output by the measuring device 1 having the lowest third priority to be output at different timing with respect to the device information having the higher third priority. For example, as shown in the upper part of FIG. 16, the CPU 31 first causes the image display unit 22 to display the heart rate image 223 related to the measuring device 3 with the higher third priority and the waveform image 222 related to the measuring device 2. Thereafter, after a predetermined time has elapsed, the CPU 31 switches the device image displayed on the image display unit 22 to the ultrasonic image 221 related to the measuring device 1 (see the lower part of FIG. 16). Thus, by shifting the output timing of a plurality of device information according to the third priority, the CPU 31 first outputs the device information within the range of the simultaneous processing amount of the user, and then the range of the simultaneous processing amount. External device information can be output. As described above, since the CPU 31 can output and control the device information at different timings according to the third priority, the user can easily grasp more device images and device sounds.

  When the device information of the plurality of measuring devices 50 indicates the same third priority, the CPU 31 sets the output timing of the plurality of device information at predetermined intervals in an arbitrary order according to the device information. You may stagger. For example, the HMD 10 predetermines a measurement device ID that prioritizes device information when the third priority is equal. CPU31 outputs each apparatus information, shifting a timing in an order from the apparatus information corresponding to the predetermined measurement apparatus ID, when several apparatus information shows the equivalent 3rd priority. Thereby, HMD10 can make a user grasp | ascertain apparatus information easily rather than outputting several apparatus information at once. In particular, when the device information is audio information, if a plurality of audio information is output from the speaker 26 at a time, it may be difficult for the user to distinguish individual audio information. In the present embodiment, since each piece of audio information is output from the speaker 26 at a predetermined interval, the user can easily discriminate between individual pieces of audio information.

  Returning to the description of FIG. The CPU 31 determines whether an instruction for ending the information output process is input via the operation unit 37 (S43). When an instruction for ending the information output process is not input (S43: NO), the CPU 31 returns the process to S11 (see FIG. 4) and repeatedly executes a series of information output processes. When the instruction for ending the information output process is input (S43: YES), the CPU 31 ends the information output process.

  The table update process will be described with reference to FIG. The table update process is executed by the main program in parallel with the information output process described above. The table update process is a process for updating the first priority and the second priority defined in the first priority table 80 and the second priority table 90, respectively, under a predetermined condition. When the table update process is started, the CPU 31 determines whether update information for updating at least one of the first priority table 80 and the second priority table 90 has been acquired via the operation unit 37. (S51). The update information may be acquired via the operation unit 37 of its own HMD 10 or may be acquired from another HMD 10 via the operation unit 37 of another HMD 10. When update information is not acquired (S51: NO), CPU31 repeats the process of S51.

  When the update information is acquired (S51: YES), the CPU 31 has specific authority based on the device ID of the HMD 10 that is the transmission source of the update information, or based on its own device ID. It is determined whether the information is based on role information (S52). In this process, the CPU 31 refers to the user information table 70 and determines that the update information is based on role information having a specific authority when the specific flag is “ON” for the device ID related to the update information. . When the update information is not based on role information having specific authority (S52: NO), the CPU 31 returns the process to the determination of S51.

  When the update information is based on role information having specific authority (S52: YES), the update information is a numerical value related to an area where update prohibition is set in the first priority table 80 and the second priority table 90. It is determined whether the information is for updating (S53). In this processing, the CPU 31 is information for updating the numerical value related to the data string in which the update prohibition flag is “ON” in the first priority table 80 and the second priority table 90. In this case, it is determined that transmission prohibition is set. When the update information is information for updating a numerical value related to an area for which update prohibition is set (S53: YES), the CPU 31 returns the process to the determination of S51.

  When the update information is not information for updating the numerical value related to the area for which update prohibition is set (S53: NO), the CPU 31 determines whether the first priority table 80 and the second priority are in accordance with the contents indicated by the update information. The first priority and the second priority in the degree table 90 are updated (S54). CPU31 returns a process to S51.

  The CPU 31 updates the first priority and the second priority suitable for each situation in the medical field, for example, according to update information based on role information having specific authority by executing the table update process. it can. Therefore, the CPU 31 can calculate the third priority calculated in accordance with the first priority and the second priority as a response to the situation of the medical field at that time. In addition, since the first priority and the second priority are set through a predetermined experiment or the like, the first priority and the second priority are updated unnecessarily by a person who does not have specific authority. That is not preferred. For this reason, useless updating of the first priority and the second priority can be prevented by limiting the users who can update the first priority and the second priority to users related to role information having specific authority. Further, the CPU 31 may perform output control of the device information according to the third priority calculated based on the first priority and the second priority updated by the user regarding the role information having specific authority. it can. Moreover, since it is also possible to carry out an update prohibition setting to the 1st priority and the 2nd priority, HMD10 will accidentally update by the table update means to the range which should not be updated among the 1st priority and the 2nd priority. It can be prevented from being updated.

  As described above, the CPU 31 refers to the user information table 70 and acquires the user ID corresponding to the HMD 10 based on the acquired device information (S11). The CPU 31 acquires device information from each of the measuring devices 50 connected to the HMD 10 (S15). CPU31 acquires measurement apparatus ID and apparatus information about each of the apparatus information acquired by the process of S15 (S18). Based on the first priority acquired in the process of S13 and the second priority acquired in the process of S21, the CPU 31 has a third priority that is a priority corresponding to each of the user ID, the measurement apparatus ID, and the apparatus state. Is calculated (S22). For this reason, for example, when the measurement values of some of the measurement devices 50 are abnormal values, for example, the first priority of the device information for each of the plurality of measurement devices according to the identification information The device information is output with the third priority based on the degree and the second priority according to the device state of the measuring device 50. Therefore, the HMD 10 calculates the third priority, so that the device information is not output based on only the predetermined priority, but according to the condition of the medical site according to the third priority. Information can be output.

  Depending on the current situation of the medical site, the user may want to view device information that is different from the device information that is determined to be higher in the third priority. In the processing of S42, the CPU 31 transmits an instruction to display the selected image 225 to the image display unit 22, and displays a device image corresponding to an input of a predetermined instruction associated with the selection image 225 being displayed on the image display unit 22. And displayed on the image display unit 22. For this reason, the user can arbitrarily select device information to be visually recognized while grasping the third priority from the selection image 225. Therefore, the convenience of the HMD 10 is improved.

  When device images based on a lot of device information are displayed on the image display unit 22 at a time, it may be difficult to grasp the device images at a time depending on the situation of the user. Similarly, even when a plurality of device sounds are output from the speaker 26 at the same time, the user may have difficulty grasping each device sound based on the device information. The CPU 31 suppresses the output of the device information with the third priority lower than the device information with the third priority higher (S41), so that the device information of the information amount suitable for the user's situation is given to the user. Can be provided.

  Since the HD 20 is worn on the user's head, the display area of the image display unit 22 has an upper limit, and it may be difficult to display a plurality of device images on the image display unit 22 at a time. Further, the user processing capability for the device image displayed on the image display unit 22 may be different for each user. The CPU 31 acquires a device information amount for each measurement device ID (S32). The CPU 31 acquires the user processing capability for each measuring device ID defined for each user ID (S35). Then, the CPU 31 calculates a processing load amount corresponding to the user ID and the measurement device ID based on the device information amount and the user processing capability (S36). Further, the CPU 31 specifies, for each user ID, a measurement device ID that can add the processing load amount within a range not exceeding the simultaneous processing amount acquired in the processing of S39 according to the third priority and the processing load amount ( S41). Then, the CPU 31 performs output control of device information related to the specified measurement device ID (S42). For this reason, the HMD 10 can output device information having an information amount corresponding to the output capability of the image display unit 22 and the speaker 26 and the user processing capability.

  Even if a plurality of device images are displayed on the image display unit 22 at once, it may be difficult for the user to appropriately process the device images. The CPU 31 can control output of device information having the same third priority at different timings according to the device information. For this reason, the convenience of HMD10 improves.

  The CPU 31 determines whether update information for updating at least one of the first priority table 80 and the second priority table 90 has been acquired (S51). When the update information is acquired (S51: YES), the CPU 31 has specific authority based on the device ID of the HMD 10 that is the transmission source of the update information, or based on its own device ID. It is determined whether the information is based on role information (S52). When the update information is based on role information having specific authority (S52: YES), the CPU 31 determines the first priority of the first priority table 80 and the second priority table 90 according to the content indicated by the update information. The second priority is updated (S54). On the other hand, when the update information is not based on role information having specific authority (S52: NO), the CPU 31 does not update the first priority and the second priority based on the update information. For this reason, in response to the determination that the user having a specific authority should update, the output of the device information is controlled according to the third priority based on the update information. Therefore, the HMD 10 can provide the user with device information that is more appropriate to the situation at the medical site.

  A user corresponding to a user ID to which specific authority is granted may end use of the HMD 10 and leave the wireless communication between the HMDs 10A, 10B, and 10C. In such a case, in the user information table 70, the characteristic flag corresponding to the next largest “NO.” Is set to “NO.” Corresponding to the user ID for which the specific flag has been previously “ON”. ON ". For this reason, every time the user ID is acquired, specific characteristics corresponding to the situation at that time are given to the user ID.

  The CPU 31 determines whether the update information is information for updating a numerical value related to an area for which update prohibition is set in the first priority table 80 and the second priority table 90 (S53). When the update information is information for updating a numerical value related to an area for which update prohibition is set (S53: YES), the CPU 31 does not update the first priority and the second priority. For this reason, the HMD 10 can prevent the table updating unit from erroneously updating the range of the first priority and the second priority that should not be updated.
