<1. Overview of Information Processing Apparatus According to One Embodiment of Present Disclosure>
First, an overview of an information processing apparatus according to an embodiment of the present disclosure will be described with reference to FIG. FIG. 1 is a diagram for describing an overview of an information processing apparatus according to an embodiment of the present disclosure.

The information processing apparatus 100 has an image display function and is worn on the head of a human body. Specifically, the information processing apparatus 100 emits image light directly through the lens toward the user's eyes as an image display function, and the virtual image formed is recognized by the user as an image. Furthermore, when the information processing apparatus 100 is worn by the user, an eyepiece optical system that emits image light positioned in front of the user's eyes is smaller than the average pupil diameter of humans. For this reason, not only image light but also external light is incident on the pupil of the user wearing the information processing apparatus 100, so that both the image and the external world enter the user's visual field.

For example, as shown in FIG. 1, the information processing apparatus 100 includes a main body 102, an arm 104, and a lens barrel 106 having an eyepiece window for emitting image light. The lens barrel 106 serves as an eyepiece optical system. The length of the lens barrel 106 is shorter than the other direction of the region in which light is emitted toward the user's pupil (hereinafter referred to as the short direction). (Also referred to as the length of the width) is smaller than the pupil diameter. The information processing apparatus 100 can be attached to the glasses 200 or the like.

Here, in an information processing apparatus in which image light and external light are incident on a pupil, in general, when a user switches a gaze target between an image and an object in the outside world, the focus of an object having different viewing distances is reduced. Switching occurs. Then, there may be a disadvantage for the user in switching the focus. For example, when there is a difference between the viewing distance to the displayed image, that is, the virtual image and the viewing distance to the object in the outside world, the user switches the focus in accordance with each viewing distance. If the focus is frequently switched, the burden on the user's eyes may increase.

Furthermore, as the difference in viewing distance increases, the time taken to switch the focus can be increased. Therefore, in situations where a short focus switching time is desired, the user may suffer disadvantages. For example, in situations where priority is given to paying attention to external conditions, such as during sports or bicycle driving, if it takes time to switch the focus from an image to an external object, it will be possible to grasp the external condition. Delay and user action will also be delayed. As a result, not only is the user's convenience impaired, but the user may be at risk.

Therefore, the present disclosure proposes the information processing apparatus 100 that can reduce the disadvantage for the user that may occur in switching the focus between the image and the outside world. Hereinafter, the information processing apparatus 100 will be described in detail. For convenience of explanation, each of the information processing apparatuses 100 according to the first and second embodiments is denoted by a number corresponding to the embodiment at the end like the information processing apparatuses 100-1 and 100-2. It distinguishes by attaching.

Specifically, the arm 104 is coupled to the end of the main body 102 and the end of the lens barrel 106 to fix the lens barrel 106. The arm 104 includes a signal line for communicating data related to an image provided from the main body 102 to the lens barrel 106.

The lens barrel 106 projects image light to the outside of the information processing apparatus 100-1. Specifically, the lens barrel 106 transmits image light provided from the main body 102 via the arm 104 to the outside of the information processing apparatus 100-1, that is, a user who wears the information processing apparatus 100-1 through an eyepiece. Project towards the eyes. Further, the physical configuration of the lens barrel 106 will be described in detail with reference to FIGS. FIG. 2 is a perspective view showing an example of a schematic physical configuration of the information processing apparatus 100-1 according to the present embodiment. FIG. 3 is a schematic physical diagram of the information processing apparatus 100-1 according to the present embodiment. It is sectional drawing which shows the example of a structure. FIG. 4 is a diagram illustrating an example of a state in which the information processing apparatus 100-1 according to the present embodiment is attached to the user.

As shown in FIGS. 2 and 3, the lens barrel 106 includes a projection unit 108, a light guide unit 110, a reflection unit 112, an eyepiece lens 114, and an adjustment unit 116 as an eyepiece optical system.

The projection unit 108 emits image light toward the light guide unit 110. For example, the projection unit 108 is a display panel that displays an image provided from the main body unit 102 as illustrated in FIG. 3, and emits image light toward the light guide unit 110 by displaying the image.

The light guide unit 110 guides the incident image light to the reflection unit 112. For example, the light guide unit 110 is a columnar member as shown in FIG. 2, and the image light projected from the projection unit 108 leaks outside the information processing apparatus 100-1 as shown in FIG. The image light is guided so as to reach the reflecting portion 112 without. The light guide unit 110 may be a cylindrical member that is hollow inside, or may be a transparent member that transmits image light.

The reflection unit 112 reflects the reaching image light toward the eyepiece lens 114. For example, as illustrated in FIG. 3, the reflection unit 112 reflects the image light guided by the light guide unit 110 toward the position of the eyepiece lens 114.

The eyepiece 114 enlarges the image. Specifically, the eyepiece refracts the image light reflected by the reflecting unit 112 and enlarges the image related to the image light.

The adjustment part 116 fixes the light guide part 110 so that a movement is possible. Specifically, the adjustment unit 116 fixes the light guide unit 110 so that the fixing position can be changed at a predetermined interval. For example, as shown in FIG. 3, the adjustment unit 116 has a convex portion corresponding to the concave portion of the light guide unit 110, and forms an adjustment mechanism for the position of the light guide unit 110. And the light guide part 110 is fixed by fitting the said convex part with the recessed part of the light guide part 110. FIG.

Further, a plurality of concave portions of the light guide portion 110 into which the convex portions of the adjustment portion 116 are fitted are provided continuously. For example, as illustrated in FIG. 3, a plurality of recesses of the light guide unit 110 are continuously provided on the side surface adjacent to the adjustment unit 116, and any one of the recesses can be fitted with the projections of the adjustment unit 116. . In addition, the convex part of the adjustment part 116 may be provided with two or more, and each of the recessed part of the light guide part 110 may be provided at predetermined intervals.

The lens barrel 106 is formed such that the length in the direction in which the length is shorter than the other direction of the region where the light is emitted toward the user's pupil is equal to or shorter than the upper limit of the pupil diameter variation. The Specifically, the lens barrel 106 is formed such that the width of the lens barrel 106 in the short direction is equal to or less than the average pupil diameter. For example, as shown in FIG. 4, the lens barrel 106 is formed such that the length L2 of the width in the short direction of the lens barrel 106 is equal to or less than the average pupil diameter L1. Since the human pupil diameter L1 generally varies in the range of about 2 mm to 8 mm, L2 can be 8 mm or less, for example, 4 mm. Further, the shape of the lens barrel 106, that is, the region from which light is emitted, may be a circle, an ellipse, or another polygon in addition to a rectangle.

(Functional configuration)
Next, a functional configuration of the information processing apparatus 100-1 according to the present embodiment will be described with reference to FIG. FIG. 5 is a block diagram illustrating an example of a schematic functional configuration of the information processing apparatus 100-1 according to the present embodiment.

As illustrated in FIG. 5, the information processing apparatus 100-1 includes an operation detection unit 120, a setting information acquisition unit 122, a control unit 124, a storage unit 126, and a display unit 128.

The operation detection unit 120 detects a user operation on the information processing apparatus 100-1. Specifically, when a user operation is performed on the information processing apparatus 100-1, the operation detection unit 120 generates operation information indicating the content of the user operation, and sends the generated operation information to the control unit 124. provide. For example, when an operation is performed on a button-type or touch-type operation unit provided separately in the information processing apparatus 100-1, the operation detection unit 120 displays operation information indicating the content of the operation on the operation unit. The generated operation information is provided to the control unit 124.

The setting information acquisition unit 122 acquires setting information according to the user's aspect related to the processing of the information processing apparatus 100-1 as the first information related to the viewing distance of the user. Specifically, the setting information acquisition unit 122 acquires information (hereinafter also referred to as application setting information) set for each application that operates in the information processing apparatus 100-1. For example, when the application is activated, the setting information acquisition unit 122 requests application setting information from the activated application, and acquires the application setting information from the requested application. Note that the setting information acquisition unit 122 may acquire application setting information from an application that is already running after the activation.

Note that the setting information acquisition unit 122 may acquire application setting information from the storage unit 126 instead of from the application. For example, the setting information acquisition unit 122 acquires application setting information corresponding to the application from the storage unit 126 when the application is activated. The application may be an application that performs main processing in an external device and provides the result of the processing to the information processing apparatus 100-1.

Also, the application setting information can be information indicating the type of application or the content handled by the application. For example, the application setting information may be meta information such as a flag indicating the type of application.

The control unit 124 controls the overall operation of the information processing apparatus 100-1. Specifically, the control unit 124 controls applications that operate on the information processing apparatus 100-1. For example, when the operation information indicating the application selection operation is provided from the operation detection unit 120, the control unit 124 selects and starts the application indicated by the operation information.

In addition, the control unit 124 performs display control of an image displayed by the display unit 128. For example, the control unit 124 acquires an image stored in the storage unit 126 and causes the display unit 128 to display the acquired image. Note that the display image may be an image obtained by imaging by an imaging device provided separately in the information processing apparatus 100-1, or may be an image acquired from an external device via communication.

In addition, the control unit 124 sets, as the second information, information for setting a virtual image distance, which is a visual distance to a virtual image related to the displayed image, based on the setting information acquired by the setting information acquisition unit 122. To decide. Specifically, the information for setting the virtual image distance includes information for prompting the user to set the virtual image distance. More specifically, the control unit 124 causes the display unit 128 to display an image that prompts the user to set the virtual image distance based on information for prompting the user to set the virtual image distance. Further, the image display control process based on the setting information will be described in detail with reference to FIGS. FIG. 6 is a diagram illustrating an example of image display control that prompts the user to set a virtual image distance in the information processing apparatus 100-1 according to the present embodiment, and FIG. 7 illustrates the information processing apparatus 100- according to the present embodiment. FIG. 6 is a diagram illustrating another example of image display control that prompts the user in 1 to set a virtual image distance.

First, the control unit 124 causes the display unit 128 to display an application selection screen. For example, the control unit 124 causes the display unit 128 to display a list of icons corresponding to the applications as illustrated in the left diagram of FIG. 6 or the left diagram of FIG. The displayed icon is switched by a horizontal scroll operation.

Next, the control unit 124 performs a process for the application specified based on the operation information provided from the operation detection unit 120. For example, the control unit 124 performs an operation indicating an operation for selecting an application from the operation detection unit 120 related to the icon indicating walking as illustrated in the left diagram of FIG. 6 or the icon indicating cycling as illustrated in the left diagram of FIG. When the information is provided, the application related to walking or cycling is started.

Next, the control unit 124 performs image display control based on the application setting information of the processed application. For example, the setting information acquisition unit 122 requests application setting information from the application started by the control unit 124, and acquires the application setting information from the application. Next, the control unit 124 determines a display image based on the application type indicated by the application setting information acquired by the setting information acquisition unit 122. Then, the control unit 124 displays the selected image on the display unit 128, and then switches the display screen to an image for which the activated application requests display.

More specifically, an image corresponding to the application type is stored in the storage unit 126, and the control unit 124 acquires an image corresponding to the application type indicated by the application setting information from the storage unit 126. Next, as shown in the middle diagram of FIG. 6 and the middle diagram of FIG. 7, the control unit 124 causes the display unit 128 to display the acquired image. Then, after a predetermined time has elapsed, the control unit 124 switches the display screen to an image requested to be displayed by the application as illustrated in the right diagram of FIG. 6 and the right diagram of FIG. 7.

Here, the image corresponding to the type of application may be an alert image that prompts the user to set a virtual image distance. For example, the alert image corresponding to the type of application is an image showing an icon for alerting or warning the user and a message indicating an operation to be performed by the user, as shown in the middle diagram of FIG. 6 and the middle diagram of FIG. possible. Further, the message includes information indicating the setting contents of the virtual image distance, for example, a message indicating that the virtual image distance should be set to one of short, middle, or long.

Also, the setting of the virtual image distance is a setting of the optical path length of the image light related to the displayed image. The setting of the optical path length of image light will be described in detail with reference to FIG. FIG. 8 is a diagram showing a change in the optical path length of the image light in the information processing apparatus 100-1 according to the present embodiment.

The virtual image distance is generally determined according to the optical path length, that is, the distance from the object to the lens. Specifically, the virtual image distance of the virtual image related to the image light projected from the projection unit 108 is the length of the path to the eyepiece 114 of the image light projected from the projection unit 108 as shown in FIG. That is, it depends on the optical path length. For example, the longer the optical path length of the image light, the longer the virtual image distance, that is, the user can see the image farther, and the shorter the optical path length of the image light, the shorter the virtual image distance, that is, the user sees the image closer.

Therefore, in the information processing apparatus 100-1, the light guide unit 110 is provided so that the position of the light guide unit 110 can be changed, and the virtual image distance is set by changing the position of the light guide unit 110. . Specifically, as shown in each drawing of FIG. 8, the position of the concave portion of the light guide unit 110 fitted to the convex portion of the adjustment unit 116 is changed by moving the light guide unit 110 in the horizontal direction. Then, the optical path length of the image light is determined according to the position of each recess. For example, when the light guide unit 110 is moved in the extraction direction, the optical path length of the image light becomes long. Therefore, the user sets the optical path length of the image light by moving the light guide unit 110 in the horizontal direction.

Furthermore, the setting content shown in the image that prompts the user to set the virtual image distance may vary depending on the type of application.

Generally, the viewing distance to the gaze target in the outside world tends to change according to the user's aspect. For example, the viewing distance to the user's gaze target is longer when the user is working at hand than when the user is looking away. For example, when working with a personal computer, the viewing distance to the gaze target is closer than when driving a car.

Therefore, in the information processing apparatus 100-1, the type of application is information determined according to the usage mode of the user, and the setting content of the virtual image distance varies depending on the usage mode.

For example, when the type of application indicates walking, an alert image that prompts an operation for setting the virtual image distance as shown in the middle diagram of FIG. 6 to the middle range, that is, an operation for moving the light guide unit 110 to an intermediate point is displayed. The When the application type indicates cycling, an operation for setting the virtual image distance as shown in the middle diagram of FIG. 7 to a long range, that is, an operation for moving the light guide unit 110 to a position extracted from the intermediate point. An alert image prompting is displayed.

Returning to the description of the functional configuration of the information processing apparatus 100-1 with reference to FIG. 5, the storage unit 126 stores information related to the processing of the control unit 124. Specifically, in the storage unit 126, the control unit 124 stores a display image on the display unit 128.

The display unit 128 displays an image based on an instruction from the control unit 124. Specifically, the display unit 128 projects, as the projection unit 108, image light related to an image instructed to be displayed by the control unit 124, and forms an image on the retina of the user.

<2-2. Device processing>
Next, processing of the information processing apparatus 100-1 according to the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart conceptually showing processing of the information processing apparatus 100-1 according to the present embodiment.

First, the information processing apparatus 100-1 waits until an application activation operation is detected (step S302). Specifically, the operation detection unit 120 detects an operation performed by the user on the information processing apparatus 100-1 and generates operation information indicating the detected operation. The control unit 124 receives the operation information generated from the operation detection unit 120 and determines whether the operation information indicates an application activation operation.

When the application activation operation is detected, the information processing apparatus 100-1 activates the application (step S304). Specifically, when it is determined that the operation information provided from the operation detection unit 120 indicates an application activation operation, the control unit 124 activates the application specified by the operation information.

Next, the information processing apparatus 100-1 acquires application setting information from the activated application (step S306). Specifically, after the application is activated, the control unit 124 requests the application setting information from the application and acquires the application setting information of the application.

Next, the information processing apparatus 100-1 displays an image based on the acquired application setting information (step S308). Specifically, the control unit 124 acquires an alert image corresponding to the type of application indicated by the acquired application setting information from the storage unit 126 and causes the display unit 128 to display the acquired alert image.

As described above, according to the first embodiment of the present disclosure, the information processing apparatus 100-1 acquires the first information related to the viewing distance of the user, and based on the acquired first information, Second information for setting a virtual image distance, which is a visual distance to a virtual image related to the displayed image, is determined. For this reason, by prompting the virtual image distance related to the image to be set according to the viewing distance of the user, the difference in the viewing distance between the image and the outside world is reduced, and in switching the focus between the image and the outside world It is possible to reduce the disadvantage for the user that may occur.

Further, the second information includes information for prompting the user to set the virtual image distance. For this reason, by causing the user to set the virtual image distance, an image having a viewing distance suitable for each user is displayed, and the burden on the user for switching the focus can be reduced.

Further, the information processing apparatus 100-1 displays an image that prompts the user to set the virtual image distance on the display unit based on the second information. For this reason, when the user is prompted to set the virtual image distance through vision, the user can easily notice the prompt.

Also, the display unit is mounted on the user's head. For this reason, it is possible to give the user a sense of reality with respect to the display by performing the display close to the user.

Further, the first information includes setting information according to the user's aspect related to the processing of the information processing apparatus 100-1. For this reason, the setting of the virtual image distance is prompted by the information that can be acquired in the existing processing of the information processing apparatus 100-1, so that the configuration of the information processing apparatus 100-1 can be prevented from becoming complicated.

Also, the above setting information includes application setting information set for each application. For this reason, by setting the virtual image distance according to the visual distance of the outside world when using the application, a virtual image distance suitable for each application can be set, reducing user dissatisfaction and burden in more usage scenes It becomes possible to do.

Further, the setting of the virtual image distance includes setting of the optical path length of image light for forming a virtual image. For this reason, by setting the virtual image distance with a configuration that is relatively easy to realize in the optical system of the information processing apparatus 100-1, it is possible to suppress complication of the configuration of the information processing apparatus 100-1. In addition, when an eyepiece optical system is used whose width in the short direction is shorter than the pupil diameter, it is easy to change the optical path length so that a virtual image distance suitable for various applications or situations can be set. It becomes.

<2-3. Modification>
Heretofore, the first embodiment of the present disclosure has been described. In addition, this embodiment is not limited to the above-mentioned example. Hereinafter, first to fifth modifications of the present embodiment will be described.

(First modification)
As a first modification of the present embodiment, the light guide unit 110 may have a lens instead of the eyepiece 114 provided in the lens barrel 106. With reference to FIG. 10, the lens barrel 106 according to this modification will be described in detail.

The light guide unit 110 incorporates a lens having a refraction action similar to that of the eyepiece lens 114. For example, as illustrated in FIG. 10, the light guide unit 110 guides the image light to the reflection unit 112 while refracting the image light projected from the projection unit 108. The lens built in the light guide unit 110 may be a gradient index lens having a positive refractive power equivalent to the eyepiece lens 114.

Thus, according to the first modification of the present embodiment, the light guide unit 110 includes a lens. For this reason, since the eyepiece 114 is not provided in the lens barrel 106, the manufacturing process of the lens barrel 106 can be simplified.

In the above description, an example in which the light guide unit 110 includes a lens instead of the eyepiece lens 114 has been described. However, the light guide unit 110 may include a lens while the eyepiece lens 114 is provided in the lens barrel 106.

(Second modification)
As a second modification of the present embodiment, the information processing apparatus 100-1 may determine information for setting the virtual image distance only in a specific case. Specifically, the control unit 124 determines whether or not the virtual image distance is changed based on the virtual image distance setting state and the application setting information, and determines a display image according to the determination result. Furthermore, with reference to FIG. 11, the process of this modification is demonstrated in detail. FIG. 11 is a diagram illustrating a change example of the virtual image distance setting state in the information processing apparatus 100-1 according to the second modification of the present embodiment.

First, when the application setting information is acquired, the control unit 124 acquires information indicating the setting state of the virtual image distance (hereinafter also referred to as virtual image distance setting information). For example, the information processing apparatus 100-1 further includes a position detection sensor 118 of the light guide unit 110. The position detection sensor 118 is provided so as to face the light guide unit 110 and the side surface of the main body of the lens barrel 106, and the sensor 118B on the light guide unit 110 side is an end of the light guide unit 110 in the direction opposite to the extraction direction. Is provided. The position detection sensor 118 detects which of the sensors 118A on the main body side of the lens barrel 106 provided in plurality is opposite to the sensor 118B on the light guide 110 side. Then, information indicating the detected position of the sensor 118A is provided to the control unit 124 as virtual image distance setting information. Note that the position detection sensor 118 may be an optical sensor such as infrared light or visible light, an ultrasonic sensor, or the like.

Next, the control unit 124 determines whether or not the setting of the virtual image distance is changed based on the acquired virtual image distance setting information and the application setting information. For example, the application setting information includes virtual image distance setting information related to a virtual image distance recommended in an application related to the application setting information. Then, the control unit 124 determines whether the virtual image distance setting information provided from the position detection sensor of the light guide unit 110 matches the virtual image distance setting information included in the application setting information.

When it is determined that the setting of the virtual image distance should be changed, the control unit 124 causes the display unit 128 to display an image corresponding to the application setting information. For example, when it is determined that the virtual image distance setting information provided from the position detection sensor of the light guide unit 110 does not match the virtual image distance setting information included in the application setting information, the control unit 124 stores the application from the storage unit 126. An alert image corresponding to the type of application indicated by the setting information is acquired, and the acquired alert image is displayed on the display unit 128.

When an alert image for setting the virtual image distance is displayed, the information processing apparatus 10-1 may allow the user to select whether or not to change the virtual image distance setting. Specifically, the control unit 124 causes the display unit 128 to display a screen for confirming whether or not the virtual image distance setting has been changed simultaneously with or after the display of the alert image.

Further, when an operation not changing the setting is performed on the confirmation screen, the control unit 124 causes the storage unit 126 to store the virtual image distance setting at that time as the virtual image distance setting in the application related to the application setting information. May be. Then, the control unit 124 performs the above-described determination process according to the stored virtual image distance setting when the application is started next time.

In the above description, the example in which the position of the light guide unit 110 is detected by the position detection sensor has been described. However, the position of the light guide unit 110 may be detected by another configuration, for example, an electrode.

In the above description, the application setting information includes the virtual image distance setting information. However, the information included in the application setting information can be compared with the information indicating the setting state of the virtual image distance. Or both may be converted. For example, the predetermined type of information included in the application setting information is based on information indicating the correspondence between the predetermined type of information and information indicating the setting state of the virtual image distance, such as a conversion table. Converted to information indicating the setting state. And the control part 124 performs the above-mentioned determination process using the information after conversion.

As described above, according to the second modification of the present embodiment, the information processing apparatus 100-1 determines whether or not the virtual image distance is changed based on the setting state of the virtual image distance and the information related to the user's viewing distance. Determination is performed, and information for setting the virtual image distance is determined according to the determination result. Therefore, only when it is recommended to change the setting of the virtual image distance, an image prompting the user to set the virtual image distance is displayed, so that the user can change the setting at an appropriate timing without giving a complicated impression to the user. Can be encouraged.

(Third Modification)
As a third modification of the present embodiment, the information processing apparatus 100-1 may automatically set the virtual image distance based on information for setting the virtual image distance. Specifically, as the setting control unit, the control unit 124 controls the setting of the virtual image distance based on the setting information according to the user's aspect related to the processing of the information processing apparatus 100-1.

For example, the information processing apparatus 100-1 separately includes a drive unit that moves the position of the light guide unit 110, and the control unit 124 controls the operation of the drive unit based on the acquired application setting information. More specifically, the drive unit includes a motor and an actuator that moves the light guide unit 110 by the power of the motor, and the control unit 124 operates the drive unit to display an application indicated by the application setting information acquired. The light guide unit 110 is moved to a position corresponding to the type.

In the above description, the example in which the optical path length is changed by moving the light guide unit 110 and the virtual image distance is changed is described. However, the optical path length may be changed by other configurations. For example, a liquid lens may be used instead of the lens such as the eyepiece 114, and the optical path length may be changed by controlling the liquid lens.

Thus, according to the third modification of the present embodiment, the information processing apparatus 100-1 controls the setting of the virtual image distance based on the information for setting the virtual image distance. For this reason, it is possible to reduce the work of the user by automatically setting the virtual image distance. In particular, when the user is exercising, it may be difficult to perform the setting operation of the information processing apparatus 100-1, so that the convenience can be further improved.

(Fourth modification)
As a fourth modification of the present embodiment, the information processing apparatus 100-1 may determine information for setting the virtual image distance based on the operating state of the information processing apparatus 100-1. Specifically, the setting information according to the user's aspect related to the processing of the information processing apparatus 100-1 includes information indicating the operation mode of the information processing apparatus 100-1 (hereinafter also referred to as operation mode information). The control unit 124 determines a display image based on the operation mode information.

For example, the operation mode may include a stationary mode that does not involve a large movement, such as a reading mode and a viewing mode, which will be described later, and a movement mode such as a walking mode, a running mode, and a cycling mode. . The operation mode is set as the state of the information processing apparatus 100-1 regardless of the application that operates.

The control unit 124 acquires information indicating the operation mode periodically or when the operation mode changes, and causes the display unit 128 to display an image corresponding to the acquired operation mode. Note that the correspondence between the operation mode and the image is stored in the storage unit 126. In addition, the image corresponding to the motion system mode is preferably an image that prompts the setting so that the virtual image distance is longer than that of the stationary mode. Further, in the exercise system mode, it is preferable to prepare images for prompting the setting so that the virtual image distance increases in the order of walking mode, running mode, and cycling mode.

Thus, according to the fourth modification example of the present embodiment, the setting information according to the user's aspect related to the processing of the information processing apparatus 100-1 is information indicating the operation mode of the information processing apparatus 100-1. including. Therefore, by using the setting information related to the entire processing of the information processing apparatus 100-1, setting work for each application when application setting information is used does not occur, and it is possible to reduce the prior setting work It becomes.

(Fifth modification)
As a fifth modification of the present embodiment, setting information related to the processing of the information processing apparatus 100-1 described above may be set based on a user operation. Specifically, the control unit 124 sets application setting information based on a user operation. For example, when the operation detection unit 120 detects an application setting information setting operation, the control unit 124 sets the application setting information in the setting content indicated by the setting operation, for example, the type of application. Note that the application setting information may be changed.

Thus, according to the fifth modification of the present embodiment, the setting information related to the processing of the information processing apparatus 100-1 is set based on a user operation. For this reason, it becomes possible to further improve a user's satisfaction because the process for setting a virtual image distance respond | corresponds to each user needs.

<3. Second Embodiment (Example of Encouraging Setting of Virtual Image Distance Based on Motion State Information)>
The information processing apparatus 100-1 according to the first embodiment of the present disclosure has been described above. Subsequently, the information processing apparatus 100-2 according to the second embodiment of the present disclosure will be described. The information processing apparatus 100-2 performs image display control for setting the virtual image distance based on information on the user's exercise state (hereinafter also referred to as exercise state information).

<3-1. Configuration of device>
(Functional configuration)
First, the physical configuration of the information processing apparatus 100-2 according to the second embodiment of the present disclosure will be described with reference to FIG. FIG. 12 is a block diagram illustrating an example of a schematic functional configuration of the information processing apparatus 100-2 according to the present embodiment.

The information processing apparatus 100-2 includes an exercise state information acquisition unit 130 instead of the setting information acquisition unit 122, as illustrated in FIG. Note that descriptions of functions that are substantially the same as the functions of the information processing apparatus 100-1 are omitted.

The exercise state information acquisition unit 130 acquires exercise state information related to the user's exercise state as an acquisition unit. Specifically, the exercise state information acquisition unit 130 acquires movement speed information related to the movement speed in the movement state of the user. For example, the exercise state information acquisition unit 130 may be an acceleration sensor that acquires acceleration information indicating the acceleration of the user. Note that the moving speed information related to the moving speed may be information related to a change in the position of the user. For example, the exercise state information acquisition unit 130 may acquire the moving speed information of the user based on a change in position information acquired from a GPS (Global Positioning System) sensor.

The exercise state information acquisition unit 130 may be a communication unit that acquires user's exercise state information from an external device via communication, and is an input unit that acquires exercise state information input by a user operation. Also good.

The control unit 124 determines information for setting the virtual image distance based on the exercise state information acquired by the exercise state information acquisition unit 130.

Here, the viewing distance to the object to be watched can vary depending on the speed of movement. Specifically, as the speed of human movement increases, an object with a long viewing distance, that is, a distant object tends to be watched. For example, while driving a bicycle, an object with a viewing distance longer than the viewing distance to the object to be watched during walking is likely to be watched.

Therefore, the control unit 124 determines information for setting the virtual image distance based on the moving speed information related to the moving speed in the moving state. Specifically, the control unit 124 selects or generates information that prompts the setting so that the virtual image distance becomes longer as the acceleration indicated by the user acceleration information acquired from the acceleration sensor is larger. For example, the control unit 124 may cause the display unit 128 to display an image including a message that prompts the user to adjust the light guide unit 110 to a position set to the virtual image distance corresponding to the acceleration indicated by the acceleration information.

For example, when the value indicated by the acceleration information indicates an acceleration of walking, an alert image that prompts an operation for setting the virtual image distance to the middle range as shown in the middle diagram of FIG. 6 is displayed. Further, when the value indicated by the acceleration information indicates an acceleration of a degree of cycling that is greater than walking, an alert image that prompts an operation for setting the virtual image distance to the long range as shown in the middle diagram of FIG. 7 is displayed.

In the above description, the example in which the exercise state information is movement speed information has been described. However, the exercise state information may be biological information of the user. Specifically, the control unit 124 selects information for setting the virtual image distance corresponding to the biological information of the user. For example, the user's biological information may be information related to pulse, respiration, body temperature, sweating, brain waves, or myoelectricity. For example, the control unit 124 selects an image that prompts the setting so that the virtual image distance becomes longer as the pulse indicated by the information related to the pulse becomes faster.

<3-2. Device processing>
Next, processing of the information processing apparatus 100-2 according to the present embodiment will be described with reference to FIG. FIG. 13 is a flowchart conceptually showing processing of the information processing apparatus 100-2 according to the present embodiment.

First, the information processing apparatus 100-2 acquires user exercise state information (step S402). Specifically, the exercise state information acquisition unit 130 acquires the acceleration information of the user every elapse of a predetermined time.

Next, the information processing apparatus 100-2 determines whether the user's exercise state specified based on the acquired exercise state information has changed (step S404). Specifically, the control unit 124 determines whether the range of the acceleration value to which the value indicated by the acceleration information acquired by the exercise state information acquisition unit 130 has changed. For example, when the value indicated by the acceleration information deviates from the range of human acceleration during walking and changes within the range of human acceleration during running, the control unit 124 determines that the range of acceleration values to which the value indicated by the acceleration information belongs. Judge that it has changed. The range of the acceleration value to which the value indicated by the past acceleration information belongs is stored in the storage unit 126.

If it is determined that the user's exercise state has changed, the information processing apparatus 100-2 displays an image based on the exercise state information (step S406). Specifically, when it is determined that the range of the acceleration value to which the value indicated by the acceleration information belongs has changed, the control unit 124 acquires an image corresponding to the value indicated by the acceleration information from the storage unit 126 and is acquired. The display unit 128 displays an image to be displayed.

As described above, according to the second embodiment of the present disclosure, the information processing apparatus 100-2 determines information for setting the virtual image distance based on the exercise state information related to the user's exercise state. For this reason, a virtual image, that is, an image is displayed at a distance suitable for the viewing distance of the user by prompting the setting of the virtual image distance based on the actual user's motion state, and the focus between the image during the exercise and the outside world is displayed. Switching can be facilitated.

Further, the above-described movement state information includes movement speed information related to the movement speed in the movement state of the user. For this reason, by facilitating the setting of the virtual image distance suitable for the viewing distance of the user that changes according to the speed of movement, it is possible to smoothly switch the focus suitable for a finer situation. The exercise state information may be a rotational motion of the information processing device 100-2 or a rotational motion of the head of the user wearing the information processing device 100-2.

Further, the above-described motion state information includes acceleration information indicating the user's acceleration. For this reason, it becomes possible to perform the process for prompting the setting of the virtual image distance in a more suitable situation and timing by more accurately grasping the speed of movement of the user.

Also, the above-described exercise state information includes user's biological information. For this reason, it is possible to suppress an increase in cost by prompting the setting of a virtual image distance that matches the user's motion state without adding a separate configuration for directly estimating the user's motion state. .

Specifically, the information processing apparatus 100-2 further includes a user attribute acquisition unit that separately acquires information indicating user attributes (hereinafter also referred to as user attribute information), and the control unit 124 includes the user attribute. The setting content of the virtual image distance is adjusted based on the user attribute information acquired by the acquisition unit.

More specifically, the user attribute information includes information indicating the user's age, sex, race, or the degree of visual acuity of the user. And the control part 124 specifies parameters, such as a correction value or a coefficient corresponding to the age etc. to which the user attribute information acquired by the user attribute acquisition part corresponds. Next, the control unit 124 adjusts the setting value of the virtual image distance by applying a parameter specified for the setting value of the virtual image distance. For example, when the age indicated by the user attribute information belongs to an age group where the possibility that the user is presbyopia (presbyopia) is higher than other age groups, the control unit 124 estimates the user's viewing distance from the motion state information. Is a predetermined distance, for example, about 30 cm, the set value of the virtual image distance is adjusted so that the virtual image distance is longer than the viewing distance, that is, the display image becomes far.

Thus, according to the modification of the present embodiment, the information processing apparatus 100-2 further includes a user attribute acquisition unit that acquires user attribute information, and the control unit 124 is acquired by the user attribute acquisition unit. The setting content of the virtual image distance is adjusted based on the user attribute information. Therefore, by adjusting the virtual image distance according to the characteristics of individual users, it is possible to meet fine user needs and improve user satisfaction.
