  In the following, for convenience of explanation, as shown in FIG. 6, a three-dimensional orthogonal coordinate system including an x-axis, a y-axis, and a z-axis is defined. The x-axis arrows in the following figures indicate the horizontal direction. The y-axis arrow points in the vertical direction or the long axis direction of the user's body. The z-axis arrow points in the depth direction. The z-axis positive direction refers to the direction of greater depth. The direction of each arrow is the same in other figures.

As shown in FIGS. 6 to 8, the eyeglass display device 100 includes a three-dimensional space detection region (3D space) 4103 </ b> D that can be detected by the infrared detection unit 410 of the operation system 400.
The three-dimensional space detection area 4103D is formed of a conical or pyramidal three-dimensional space from the infrared detection unit 410.

That is, the infrared detection unit 410 can detect the infrared rays emitted from the infrared irradiation element 411 by the infrared detection camera 412, and thus can recognize a gesture in the three-dimensional space detection region 4103D.

The region 2203D is visually recognized as being virtually displayed with a depth. The depth corresponds to the thickness in the depth direction (z-axis direction) of the virtual three-dimensional shape of the virtual image display area 2203D. Therefore, the depth is provided according to the thickness of the virtual three-dimensional shape in the depth direction (z-axis direction).
That is, although it is actually displayed on the semi-transmissive display 220 of the eyeglass display device 100, the user recognizes the right-eye image through the right-eye semi-transmissive display 220 in the three-dimensional space area 2203DR, and the left-eye image is The light is transmitted through the transflective display 220 on the left eye side and recognized by the three-dimensional space area 2203DL.

Also, as shown in FIG. 10, a virtual image display area 2203D is output from the input / output device 900, and the infrared detection unit 410 is in the same direction as the input / output device 900 (all directions on the z-axis positive side with respect to the xy plane). The three-dimensional space detection region 4103D may be formed.
Even in this case, the virtual image display area 2203D by the input / output device 900 is generated as a space area shared with the three-dimensional space detection area 4103D.

  Next, as illustrated in FIG. 11, the virtual image display area 2203 </ b> D may be output from the input / output device 900 in the vertically upward direction (y-axis positive direction). Also in FIG. 11, similarly to FIGS. 9 and 10, the virtual image display area 2203 </ b> D by the input / output device 900 is generated as a space area shared with the three-dimensional space detection area 4103 </ b> D.

  Although not shown, the input / output device 900 is arranged above the three-dimensional space detection region 4103D (y-axis positive direction side), and the virtual image display region 2203D is vertically downward (y-axis negative direction). It may be output, may be output from the horizontal direction (x-axis direction), or may be output from the rear upper side (z-axis negative direction and y-axis positive direction) like a projector or a movie theater.

  First, as shown in FIG. 12, in general, the user horizontally moves both hands around the shoulder joints of the right shoulder joint RP and the left shoulder joint LP, so that the area where both hands can move is surrounded by a dotted line. The moving area L and the moving area R become the same.

  In addition, as shown in FIG. 13, in general, the user vertically moves both hands around the shoulder joints of the right shoulder joint RP and the left shoulder joint LP, so that the area where both hands can move is surrounded by a dotted line. The moving area L and the moving area R become the same.

  That is, as shown in FIGS. 12 and 13, the user has a spherical shape (having an arch-shaped curved surface convex in the depth direction) with both hands rotating around the right shoulder joint RP and the left shoulder joint LP, respectively. Can be moved.

Next, the three-dimensional space detection area 4103D by the infrared detection unit 410, the area where the virtual image display area may exist (the virtual image display area 2203D is illustrated in FIG. 12), the arm movement area L, and the movement area R are combined. A space area that overlaps with the selected area is set as the operation area 410c.
Further, a portion other than the operation region 410c in the three-dimensional space detection region 4103D and a portion overlapping with the combined region of the arm movement region L and the movement region R is set as the gesture region 410g.

  Here, the operation region 410c has a three-dimensional shape in which the surface farthest in the depth direction is a curved surface curved in an arch shape convex in the depth direction (z-axis positive direction), whereas the virtual image display region 2203D has a depth of The surface farthest in the direction has a three-dimensional shape that is a plane. Thus, due to the difference in the shape of the surface between the two regions, the user feels uncomfortable in the operation. In order to remove the uncomfortable feeling, adjustment is performed by a calibration process. Details of the calibration process will be described later.

(Description of calibration)
Next, the calibration process will be described. FIG. 14 is a flowchart for explaining the calibration process.

As shown in FIGS. 12 and 13, when the user tries to move his / her hand along the virtual image display area 2203D, the user needs to move along a plane without assistance. Therefore, a calibration process is performed to facilitate the operation in the virtual image display area 2203D by a recognition process described later.
In the calibration process, the finger length, hand length, and arm length that are different for each user are also adjusted.

Hereinafter, description will be made with reference to FIG. First, the user wears the eyeglass display device 100 and extends both arms to the maximum. As a result, the infrared detection unit 410 recognizes the maximum area of the operation area 410c (step S11).
That is, since the length of the finger, the length of the hand, and the length of the arm, which are different for each user, are different depending on the user, the operation area 410c is adjusted.

  Next, in the eyeglass display device 100, the display position of the virtual image display area 2203D is determined (step S12). That is, if the virtual image display area 2203D is arranged outside the operation area 410c, the operation by the user becomes impossible, so the virtual image display area 2203D is arranged inside the operation area 410c.

Subsequently, the maximum area of the gesture area 410g is set in a position that does not overlap the display position of the virtual image display area 2203D within the three-dimensional space detection area 4103D of the infrared detection unit 410 of the eyeglass display device 100 (step S13). .
The gesture region 410g is preferably arranged so as not to overlap the virtual image display region 2203D and has a thickness in the depth direction (z-axis positive direction).

  In the present embodiment, the operation area 410c, the virtual image display area 2203D, and the gesture area 410g are set by the above method.

  Next, calibration of the virtual image display area 2203D in the operation area 410c will be described.

  When it is determined that the user's finger, hand, or arm exists outside the virtual image display area 2203D in the operation area 410c, rounding is performed so that the user's finger, hand, or arm exists inside the virtual image display area 2203D (step) S14).

As shown in FIGS. 12 and 13, in the vicinity of the center of the image virtually displayed by the transflective display 220, when both arms are extended to the maximum, both hands remain in the virtual image display area 2203D. Without any deviation in the depth direction (z-axis positive direction). Further, at the end of the virtually displayed image, it is not determined that both hands are present in the virtual image display area 2203D unless both arms are extended to the maximum.
Therefore, if the signal from the infrared detection unit 410 is used without processing, even if the user moves away from the virtual image display area 2203D, it is difficult for the user to experience such a state.

Therefore, in the process of step S14 in the present embodiment, the signal from the infrared detection unit 410 is processed so as to correct the hand protruding outside from the virtual image display area 2203D within the virtual image display area 2203D. To do.
As a result, the user can operate from the center to the end of the flat virtual image display area 2203D having a depth with both arms extended to the maximum or slightly bent.

  In the present embodiment, the virtual image display area 2203D is made up of a three-dimensional space area whose plane farthest in the depth direction is a plane, but is not limited to this, and is the plane area farthest in the depth direction. It is good also as consisting of the three-dimensional space area | region which is a curved surface of the shape along the surface furthest in the depth direction of L and R. As a result, the user can operate from the center to the end of the flat virtual image display area 2203D having a depth with both arms extended to the maximum or slightly bent.

Further, the transflective display 220 displays a rectangular image in the virtual image display area 2203D. For example, as shown in FIG. 5B, a rectangular image is displayed (step S15).
Subsequently, display is performed when the periphery of the image is surrounded by a finger on the transflective display 220 (step S16). Here, a finger-shaped image may be displayed lightly in the vicinity of the image, or an instruction may be transmitted from the speaker to the user by voice instead of being displayed on the transflective display 220.

In accordance with the instruction, the user places his / her finger on the portion where the image can be seen as shown in FIG. Then, the correlation between the display area of the virtual image display area 2203D and the infrared detection unit 410 is automatically adjusted (step S17).
In the above description, a rectangle is formed with a finger, and is matched with the rectangle thus determined and the rectangle of the outer edge of the image. Thus, the rectangular viewing size and position determined by the finger are matched with the rectangular viewing size and position of the outer edge of the image. However, the method of determining the shape with the finger is not limited to this, and any other method such as a method of tracing the outer edge of the displayed image with a finger, a method of pointing a plurality of points on the outer edge of the displayed image with a finger, etc. It may be. Moreover, you may perform these methods about the image of several sizes.

  In the above description of the calibration process, only the case of the eyeglass display device 100 has been described. However, in the case of the input / output device 900, an image is displayed in the process of step S11, and the process of step S17. The correlation between the image and the infrared detection unit 410 may be adjusted.

(Finger, palm, arm recognition)
Next, finger recognition will be described, and then palm recognition and arm recognition will be described in this order. FIG. 15 is a schematic diagram illustrating an example of finger recognition. 15A is an enlarged view of the vicinity of the tip of the finger, and FIG. 15B is an enlarged view of the vicinity of the base of the finger. FIG. 16 is a flowchart illustrating an example of finger recognition processing.

As shown in FIG. 16, in this embodiment, the device is initialized (step S21). Next, the infrared ray irradiated from the infrared irradiation element 411 and reflected by the hand is detected by the infrared detection camera 412 (step S22).
Next, the image data is replaced with a distance in units of pixels by the infrared detection unit 410 (step S23). In this case, the brightness of infrared rays is inversely proportional to the cube of the distance. Using this, a depth map is created (step S24).

Next, an appropriate threshold value is provided for the created depth map. Then, the image data is binarized (step S25). That is, the noise of the depth map is removed.
Subsequently, a polygon having about 100 vertices is created from the binarized image data (step S26). Then, a low-pass filter (LPF) so the vertex becomes smooth, by creating a new polygon having more vertexes p _n, it extracts the outline OF hand shown in FIG. 15 (step S27).
In the present embodiment, the number of vertices extracted to create a polygon from the binarized data in step S26 is about 100. However, the number of vertices is not limited to this, and 1000 or any other arbitrary number is used. It may be a number.

From the set of vertices _{p n} of new polygons created in step S27, using Convex Hull, it extracts the hull (step S28).
Thereafter, a shared vertex p ₀ between the new polygon created in step S27 and the convex hull created in step S28 is extracted (step S29). The shared vertex p ₀ itself extracted in this way can be used as the finger tip point.
Further, another point calculated based on the position of the vertex p ₀ may be used as the tip point of the finger. For example, it is also possible to calculate the center of the inscribed circle of the contour OF as the tip points P0 at the vertex p ₀ as shown in FIG. 15 (A).

Then, as shown in FIG. 15, a vector of the reference line segment PP ₁ passing through the pair of left and right vertices p ₁ adjacent to the vertex p ₀ is calculated. Thereafter, the side pp ₂ connecting the vertex p ₁ and the adjacent vertex p ₂ is selected, and its vector is calculated. Similarly, using the vertex p _n constituting the outer OF, repeated along the process of obtaining the vector edge to the outer periphery of the outer OF. It examines the respective sides of the orientation and the reference line segment PP ₁ orientation determines that the sides pp _k comprising parallel close to the reference line segment PP ₁ is present at the position of the crotch of the finger. Then, based on the position of the side pp _k , the root point P1 of the finger is calculated (step S30). A finger skeleton is obtained by connecting the finger tip point P0 and the finger root point P1 with a straight line (step S31). By obtaining the skeleton of the finger, the extension direction of the finger can be recognized.
By performing the same process for all fingers, skeletons for all fingers are obtained. Thereby, the hand pose can be recognized. That is, it is possible to recognize which of the thumb, the index finger, the middle finger, the ring finger, and the little finger is spread and which finger is gripped.

  Subsequently, a difference in hand pose is detected in comparison with the image data of several frames performed immediately before (step S32). That is, the hand movement can be recognized by comparing with the image data of the last several frames.

  Next, the recognized hand shape is delivered to the event service unit 460 as gesture data (step S33).

  Next, the application software unit 459 performs a behavior corresponding to the event (step S34).

Subsequently, the display service unit 462 requests drawing in the three-dimensional space (step S35).
The graphic operation unit 463 refers to the calibration data recording unit 457 using the calibration service unit 461, and corrects the display (step S36).
Finally, display is performed on the transflective display 220 by the display arithmetic unit 464 (step S37).

In the present embodiment, the root point of the finger is detected by the process of step S30 and the process of step S31, but the root point detection method is not limited to this. For example, first, the length of the reference line segment PP ₁ that connects a pair of adjacent vertices p ₁ on one side and the other side of the vertex p ₀ is calculated. Then, to calculate the length of a line connecting between the pair of vertices p ₂ at the one side and the other side. Similarly, the length of the line segment connecting the pair of vertices on the one side and the other side is calculated in the order from the vertex located closer to the vertex p ₀ to the vertex located further away. Such line segments are approximately parallel to each other without intersecting within the outer shape OF. When the vertices at both ends of the line segment are at the finger portion, the length of the line segment corresponds to the width of the finger, so the amount of change is small. On the other hand, when at least one of the vertices at both ends of the line segment reaches the crotch portion of the finger, the amount of change in the length increases. Therefore, the root point can be determined by detecting the line segment that does not exceed the predetermined amount and the farthest from the apex p ₀ and extracts one point on the detected line segment. .

(Palm recognition)
Next, FIG. 17 is a schematic diagram illustrating an example of palm recognition.

  As shown in FIG. 17, after performing finger recognition, the maximum inscribed circle C inscribed in the outer shape OF of the image data is extracted. The position of the maximum inscribed circle C can be recognized as the palm position.

  Next, FIG. 18 is a schematic diagram illustrating an example of thumb recognition.

  As shown in FIG. 18, the thumb has different characteristics from the other four fingers of the index finger, middle finger, ring finger, and little finger. For example, among the angles θ1, θ2, θ3, and θ4 formed by the straight lines connecting the center of the maximum inscribed circle C indicating the palm position and the root point P1 of each finger, θ1 involving the thumb tends to be the largest. is there. Of the angles θ11, θ12, θ13, and θ14 formed by the straight lines connecting the tip point P0 of each finger and the root point P1 of each finger, θ11 involving the thumb tends to be the largest. The thumb is determined based on such a tendency. As a result, it is possible to determine whether the hand is the right hand or the left hand, or the front or back of the palm.

(Arm recognition)
Next, arm recognition will be described. In the present embodiment, arm recognition is performed after any of a finger, palm, and thumb is recognized. Note that the arm recognition may be performed before recognizing any one of the finger, the palm, and the thumb, or at least one of them.

In the present embodiment, the polygon is extracted in a larger area than the hand-shaped polygon of the image data. For example, the process of steps S21 to S27 is performed in a range of 5 cm to 100 cm in length, and more preferably in a range of 10 cm to 40 cm to extract the outer shape.
Thereafter, a rectangular frame circumscribing the extracted outer shape is selected. In the present embodiment, the square frame is a parallelogram or a rectangle.
In this case, since the parallelogram or rectangle has long sides facing each other, the arm extending direction can be recognized from the long side extending direction, and the arm direction can be determined from the long side direction. I can do it. Note that, similarly to the process of step S32, the movement of the arm may be detected in comparison with the image data of the previous few frames.

  In the above description, the finger, palm, thumb, and arm are detected from the two-dimensional image. However, the present invention is not limited to the above, and the infrared detection unit 410 may be further added, and only the infrared detection camera 412 is used. May be further added to recognize a three-dimensional image from a two-dimensional image. As a result, the recognition accuracy can be further increased.

(Example of transflective display)
Next, FIG. 19 is a schematic diagram illustrating an example of display on the transflective display 220 of the eyeglass display device 100.

  As shown in FIG. 19, an advertisement 221 is displayed on a part of the transflective display 220 of the glasses display device 100, a map 222 is displayed on a part of the display, and the other part is a half of the glasses display device 100. A landscape 223 is visually recognized through the transmissive display 220, and a weather forecast 224 and a time 225 are also displayed.

(Details of operation area 410c)
20 to 23 are schematic diagrams illustrating other examples of the operation area 410c described with reference to FIGS.
20 and 21 are schematic views showing a state in which the user is visually recognized from above, and FIGS. 22 and 23 are schematic views showing a state in which the user is visually recognized from the side.

  FIG. 20 shows a case where the user fully extends the arm arm1, the arm arm2, and the hand H1, and the hand H1 in this case passes through the movement locus RL1 centering on the right shoulder joint RP. In this case, the radius of curvature of the movement locus RL1 is rad1.

On the other hand, FIG. 21 shows a case where the user bends the arm arm1 and the arm arm2, and the hand H1 in this case passes through the movement locus RL2.
That is, in FIG. 21, the user is trying to move the hand H1 in the horizontal direction, but will pass through a movement locus RL2 that is close to a straight line. In this case, the radius of curvature of the movement locus RL2 is rad2. Here, of course, based on ergonomics, the radius of curvature rad1 is smaller than the radius of curvature rad2.

  In this case, even if the control unit 450 detects the movement locus RL1 from the infrared unit 410, it calibrates that the movement is linear. Similarly, the control unit 450 calibrates that the movement is linear even when the movement locus RL2 is detected.

  Next, FIG. 22 shows a case where the user fully extends the arm arm1, the arm arm2, and the hand H1, and the hand H1 in this case passes through the movement locus RL3 centering on the right shoulder joint RP. In this case, the radius of curvature of the movement locus RL3 is rad3.

On the other hand, as shown in FIG. 23, the user shows a case where the arm arm1 and the arm arm2 are bent, and the hand H1 in this case passes through the movement locus RL4.
That is, in FIG. 23, the user is trying to move the hand H1 in the vertical direction, but passes the movement locus RL4 that is close to a straight line. In this case, the radius of curvature of the movement locus RL4 is rad4. Here, based on ergonomics, the curvature radius rad3 is naturally smaller than the curvature radius rad4.

  In this case, even if the control unit 450 detects the movement locus RL3 from the infrared unit 410, it calibrates that the movement is linear. Similarly, the control unit 450 calibrates that the movement is a linear movement even when the movement locus RL4 is detected.

(Medical head mounted display)
Hereinafter, a specific example in which the eyeglass display device 100 is used as the medical head mounted display 100 will be described.

The user wearing the medical head mounted display 100 selects one device from the device list displayed on the transflective display 220 using the hand H1. Here, the hand H1 may be in a state where surgical gloves are worn or not. Moreover, as shown in FIG. 26, the case where the surgical lighting device 901 is selected will be described.

  The control unit 450 determines whether one device is selected from the device list (step S73). If it is determined that it has not been selected (No in step S73), the control unit 450 waits. On the other hand, when it determines with having been selected (Yes of step S73), the control unit 450 displays the operation list of the selected apparatus on the semi-transparent display 220 (step S74).

The user wearing the medical head mounted display 100 selects one operation from the operation list displayed on the translucent display 220 using the hand H1. Here, the hand H1 may be in a state where surgical gloves are worn or not.
Here, as shown in FIG. 26, a case where the illuminance is increased by narrowing the focus of the surgical lighting apparatus 901 will be described.

The control unit 450 determines whether or not one operation is selected from the operation list (step S75). If it is determined that it has not been selected (No in step S75), the control unit 450 waits. On the other hand, when it determines with having selected (Yes of step S75), the control unit 450 transmits the operation information of the selected apparatus to an apparatus (step S76).

As a result, the user wearing the medical head mounted display 100 can increase the illuminance by narrowing the focus of the surgical lighting apparatus 901 to the intended position. Therefore, the operation of the surgical lighting apparatus 901 can be performed while confirming the affected area of the patient without instructing the nurse to operate the surgical lighting apparatus 901 as in the past. As a result, the number of nurses can be reduced, and the surgical lighting apparatus 901 can be operated as the doctor desires, not by voice instructions.

  Next, FIG. 27 is a schematic diagram illustrating an example of a state in which the biological information is displayed on the translucent display 220 by communicating with the biological information monitor device 902.

As shown in FIG. 33, the control unit 450 causes the transflective display 220 to display a button indicating whether or not to start imaging (step S81).
If it is determined that imaging has not started (No in step S81), the process stands by. On the other hand, when it is determined that imaging is started (Yes in step S81), imaging is started and imaging data is recorded in the medical head mounted display 100 (step S82).

Next, the control unit 450 determines whether or not to send imaging data to the external recording device (step S83).
If it is determined not to transmit (No in step S83), the process proceeds to the next process. On the other hand, when it determines with transmitting (Yes of step S83), while starting imaging, imaging data is recorded on an external recording device (step S84). Here, the external recording device may be a hard disk drive or cloud computing.

Next, the control unit 450 determines whether or not to send imaging data to the external monitor (step S85). When it is determined that the imaging data is not transmitted to the external monitor (No in step S85), the control unit 450 ends the process.
On the other hand, when it is determined that the imaging data is to be transmitted to the external monitor (Yes in step S85), the control unit 450 transmits the imaging data to the external monitor (step S86).
