As described above, when a display object is displayed constantly at a fixed position on the display surface, e.g., when a stationary icon is displayed on the display surface, there is a concern that the user may feel discomfort since the user's field of view is blocked.
Therefore, for example, the display control device according to this embodiment controls the display of a display object which is displayed on the display surface in the display device (a display device which is mounted on a user so that the display surface capable of displaying a display object is positioned ahead of the user) according to this embodiment as shown in A and B of
In greater detail, for example, the display control device according to this embodiment transfers and displays a display object which is displayed on the display surface from a reference position corresponding to the display object in accordance with the movement of the display device according to this embodiment. In addition, the display control device according to this embodiment transfers and displays the transferred display object from the position after the transfer to the reference position. Here, examples of the transfer of the display object according to the movement of the display device according to this embodiment include “transferring a display object which is displayed on the display surface from a reference position corresponding to the display object in a direction opposite to an axial direction in which the movement of the display device according to this embodiment is detected.” In addition, the transfer of the display object according to this embodiment from the position after the movement to the reference position is, for example, automatically performed. In greater detail, for example, the display control device according to this embodiment transfers the transferred display object from the position after the transfer to the reference position “without user's operation” or “regardless of the motion of the user.” Specific examples of the transfer of the display object according to the movement of the display device according to this embodiment will be described later.
Here, for example, the reference position according to this embodiment is a position which becomes a reference when the display object is disposed. For example, the reference position according to this embodiment is expressed in coordinates with their origin at a position set in a local space (a coordinate system transferring along with the direction of the user on which the display device according to this embodiment is mounted). Examples of the reference position according to this embodiment include a position on the display surface which is expressed in coordinates with their origin at a predetermined position (for example, a position at the lower-left corner of the display surface, a position at the upper-left corner of the display surface, a central position of the display surface, and the like) on the display surface.
Examples of the reference position according to this embodiment include a unique position for each display object. However, the reference position according to this embodiment is not limited thereto. For example, the reference position according to this embodiment may be a changeable position which is changed based on a user's operation such as a user's operation of transferring a display object.
In addition, examples of the axial direction in which the movement according to this embodiment is detected (hereinafter, simply referred to as an “axial direction according to this embodiment”) include a yaw direction, a pitch direction, and a roll direction. The axial direction according to this embodiment is not limited thereto. For example, the axial direction according to this embodiment may include a front-back direction of the user on which the display device according to this embodiment is mounted.
The display control device according to this embodiment acquires information related to the movement of the display device according to this embodiment based on detection data which shows the movement and is detected by a sensor (or an external sensor which is connected to the display device according to this embodiment and is capable of detecting the movement of the display device according to this embodiment; the same applies hereinafter), capable of detecting the movement of the display device according to this embodiment, of the display device according to this embodiment. Here, examples of the information related to the movement according to this embodiment include “axial direction in which the movement according to this embodiment is detected,” “moving direction and moving quantity (when the detected axial direction is a yaw direction or a pitch direction)” “inclination direction and inclination quantity (when the detected axial direction is a roll direction).”
For example, the display control device according to this embodiment moves a display object based on the movement of the display device according to this embodiment as described above by performing the display control process according to this embodiment. Accordingly, when the display control device according to this embodiment performs the display control process according to this embodiment, it is possible to decrease the possibility of giving a user a feeling of discomfort which is caused since the user's field of view is blocked, as in the case in which a display object is displayed constantly at a fixed position on the display surface.
Thus, the display control device according to this embodiment can decrease the possibility of giving a user a feeling of discomfort.
The movement of a display object which is realized through the display control process according to this embodiment is not limited to the above-described examples.
For example, when the axial direction according to this embodiment is a yaw direction, a pitch direction, or a roll direction, the display control device according to this embodiment may selectively transfer the transferred display object from the position after the transfer to the reference position for each axial direction based on the setting for each axial direction according to this embodiment.
Specifically, for example, when the axial direction according to this embodiment is a roll direction, the display control device according to this embodiment does not transfer the display object transferred from the reference position from the position after the transfer to the reference position.
In addition, for example, when the axial direction according to this embodiment is a yaw direction or a pitch direction, the display control device according to this embodiment selectively transfers the transferred display object from the position after the transfer to the reference position based on setting information (data) which is set through a user's operation or the like and indicates whether to transfer the display object from the position after the transfer to the reference position. For example, when the setting information indicates “transferring the display object from the position after the transfer to the reference position,” the display control device according to this embodiment selectively transfers the display object transferred from the reference position from the position after the transfer to the reference position. For example, when the setting information does not indicate “transferring the display object from the position after the transfer to the reference position,” the display control device according to this embodiment does not transfer the display object transferred from the reference position from the position after the transfer to the reference position. Here, examples of the setting information according to this embodiment include a graph indicating whether to transfer the display object from the position after the transfer to the reference position.
Needless to say, when the axial direction according to this embodiment is a roll direction, for example, the display control device according to this embodiment can selectively transfer the transferred display object from the position after the transfer to the reference position based on the setting information. In the following description, a case in which, when the axial direction according to this embodiment is a roll direction, the display control device according to this embodiment does not transfer the display object transferred from the reference position from the position after the transfer to the reference position will be exemplified.
Hereinafter, the display control process according to this embodiment will be described in more detail. In the following description, a case in which the display object according to this embodiment which is displayed on the display surface is an icon will be exemplified. Needless to say, the display object according to this embodiment is not limited to the icon.

Next, referring to B1 of
Here, for example, the display control device according to this embodiment transfers the display object at a predetermined set speed. The predetermined speed according to this embodiment may be, for example, a preset fixed value or a variable value which can be set through a user's operation or the like.
The method of setting the transferring speed of the display object according to this embodiment is not limited thereto.
For example, when transferring a display object, the display control device according to this embodiment may change the transferring speed of the display object based on one or more of the reference position corresponding to the display object, the position at which the display object is displayed, and the moving quantity which is calculated based on the detected movement of the display device according to this embodiment. Here, the position at which the display object according to this embodiment is displayed represents, for example, the reference position according to this embodiment, the position of the display object during transfer, or the position of the display object after the transfer. In addition, for example, the position at which the display object according to this embodiment is displayed is expressed in coordinates with their origin at a predetermined position on the display surface, as in the case of the reference position according to this embodiment. An example of the method of calculating the moving quantity according to this embodiment will be described later.
When changing the transferring speed of the display object based on the reference position corresponding to the display object or the position at which the display object is displayed, the display control device according to this embodiment determines a transferring speed of the display object corresponding to the reference position or the position at which the display object is displayed, using, for example, a table or the like in which coordinates corresponding to the positions on the display surface and transferring speeds of the display object are associated with each other. When changing the transferring speed of the display object based on the calculated moving quantity, the display control device according to this embodiment determines a transferring speed of the display object corresponding to the calculated moving quantity, using, for example, a table or the like in which moving quantities and transferring speeds of the display object are associated with each other. When changing the transferring speed of the display object based on two or more indices among the reference position corresponding to the display object, the position at which the display object is displayed, and the moving quantity which is calculated based on the detected movement of the display device according to this embodiment, the display control device according to this embodiment determines a transferring speed of the display object by taking an average of speed specified using, for example, a table for each index. Needless to say, the method of determining the transferring speed of the display object in the display control device according to this embodiment is not limited to the above-described examples.
In addition, the display control device according to this embodiment can also adjust the transferring speed of the display object using a set weighting coefficient.
Here, examples of the weighting coefficient according to this embodiment include a coefficient which is set for each display object, a coefficient which is set for each display object type, and a weighting coefficient common to the display objects. In addition, the weighting coefficient according to this embodiment may be a preset fixed value or a variable value which can be set through a user's operation or the like.

Next, an example of the display control process according to this embodiment which is capable of realizing the display of a display object as shown in, for example, A1, B1, and C1 of
For example, an angle of the display device according to this embodiment which is specified based on detection data acquired from the sensor, capable of detecting the movement of the display device according to this embodiment, of the display device according to this embodiment is represented by theta. For example, the display device according to this embodiment calculates the moving direction and the moving quantity based on the detected movement through the following expression 1, based on an angle theta0 at a first point of time and an angle theta1 at a second point of time (a point of time after the first point of time). Here, the positive and negative values of delta theta shown in expression 1 represent the moving direction, and the absolute value of delta theta represents the moving quantity. In the example shown in
Δθ=θ1−θ0 (Expression 1)
The display control device according to this embodiment determines whether the absolute value of the calculated delta theta (that is, the moving quantity according to this embodiment) is equal to or higher than a predetermined set threshold value (S100). Here, the predetermined threshold value related to the process of step S100 may be a preset fixed value or a variable value which can be appropriately set through a user's operation or the like.
The process of step S100 is not limited to the example shown in
In step S100, when the absolute value of the calculated delta theta is determined to be equal to or higher than the predetermined set threshold value, the display control device according to this embodiment determines whether the value of the calculated delta theta is a negative value (S102).
When the value of the calculated delta theta is determined to be a negative value in step S102, the display control device according to this embodiment transfers the display object in a positive direction of the X-axis on the display surface (S104). When the value of the calculated delta theta is determined to be a positive value in step S102, the display control device according to this embodiment transfers the display object in a negative direction of the X-axis on the display surface (S106). Here, the display control device according to this embodiment transfers the display object at a speed set for each display object in steps S104 and S106.
For example, when the process of step S104 or S106 is performed, “transferring each icon to the left (a direction opposite to the axial direction in which the movement of the display device is detected) in
In addition, when the absolute value of the calculated delta theta is not determined to be equal to or higher than the predetermined set threshold value in step S100, the display control device according to this embodiment determines whether the display object is positioned at the reference position (S108). The display control device according to this embodiment determines that the display object is positioned at the reference position when, for example, the current coordinates of the display object are the same as the coordinates corresponding to the reference position.
When the display object is determined to be positioned at the reference position in step S108, the display control device according to this embodiment terminates the display control process according to this embodiment.
In addition, when the display object is not determined to be positioned at the reference position in step S108, the display control device according to this embodiment moves the display object toward the reference position (S110). The display control device according to this embodiment repeats the process from step S100.
For example, when the process of step S110 is performed, “transferring the icon transferred from the position corresponding to the reference position according to this embodiment which is shown in A1 of

First, referring to A1 of
Next, referring to B1 of
Here, for example, the display control device according to this embodiment transfers the display object by rotating the display object at a predetermined set speed. The predetermined speed according to this embodiment may be, for example, a preset fixed value or a variable value which can be set through a user's operation or the like.
The method of setting the transferring speed of the display object according to this embodiment when rotating and thereby transferring the display object is not limited thereto.
For example, when rotating and thereby transferring the display object, the display control device according to this embodiment may change the transferring speed of the display object based on one or both of the reference position corresponding to the display object and the calculated inclination quantity. An example of the method of calculating the inclination quantity according to this embodiment will be described later.
When changing the transferring speed of the display object based on the reference position corresponding to the display object, the display control device according to this embodiment determines a transferring speed of the display object corresponding to the reference position, using, for example, a table or the like in which coordinates corresponding to the positions on the display surface and rotation speeds of the display object are associated with each other. When changing the transferring speed of the display object based on the calculated inclination quantity, the display control device according to this embodiment determines a transferring speed of the display object corresponding to the calculated inclination quantity, using, for example, a table or the like in which inclination quantities and rotation speeds of the display object are associated with each other. When changing the transferring speed of the display object based on both indices of the reference position corresponding to the display object and the inclination quantity which is calculated based on the detected movement of the display device according to this embodiment, the display control device according to this embodiment determines a transferring speed of the display object by taking an average of speed specified using, for example, a table for each index. Needless to say, the method of determining the transferring speed of the display object in the display control device according to this embodiment when rotating and thereby transferring the display object is not limited to the above-described examples.
The display control device according to this embodiment can also adjust the transferring speed of the display object using a set weighting coefficient as in the display control process according to the first example shown in the above-described (1).
When the axial direction according to this embodiment related to the detected movement of the display device according to this embodiment is a roll direction, the display control device according to this embodiment transfers the display object as shown in, for example, A1, B1, and C1 of
When the axial direction according to this embodiment related to the detected movement of the display device according to this embodiment is a roll direction, the method of expressing a display object which is displayed on the display surface as a result of the transfer of the display object by the display control device according to this embodiment is not limited to the examples shown in A1, B1, and C1 of

The display control device according to this embodiment calculates an inclination theta of the display device according to this embodiment based on the detected movement of the display device according to this embodiment (S200). For example, the display control device according to this embodiment calculates the inclination theta based on detection data acquired from the sensor, capable of detecting the movement of the display device according to this embodiment, of the display device according to this embodiment. Here, the positive and negative values of the inclination theta represent the inclination direction, and the absolute value of the inclination theta represents the inclination quantity.
When the inclination theta (that is, the inclination direction and the inclination quantity based on the detected movement) is calculated in step S200, the display control device according to this embodiment transfers the display object by rotating the display object by the absolute value of the inclination theta (that is, inclination quantity) in a direction opposite to the direction represented by the value of the inclination theta (that is, the inclination direction).
For example, when performing the process of step S202, “transferring the display object through the rotation of the display object by the calculated inclination quantity in a direction opposite to the calculated inclination direction” is realized.
For example, the display control device according to this embodiment performs the process shown in
The display control process according to the third example according to this embodiment is not limited to, for example, the example shown in

(4) Fourth Example of Display Control Process According to Embodiment: Example of Process for Case in which Axial Direction According to Embodiment Includes Two or More Axial Directions Among Yaw Direction, Pitch Direction, and Roll Direction
In the display control process according to the first example shown in the above-described (1) to the display control process according to the third example shown in the above-described (3), an example of the display control process for the case in which the axial direction according to this embodiment is any of a yaw direction, a pitch direction, and a roll direction is shown. However, the display control process according to this embodiment is not limited to the process for the case in which the axial direction according to this embodiment is any of a yaw direction, a pitch direction, and a roll direction.
For example, when the axial direction according to this embodiment includes two or more axial directions among a yaw direction, a pitch direction, and a roll direction, the display control device according to this embodiment can also perform the processes corresponding to the respective axial directions according to this embodiment (the display control process according to the first example shown in the above-described (1) to the display control process according to the third example shown in the above-described (3)) in parallel. That is, for example, the display control device according to this embodiment can combine two or more of the display control process according to the first example shown in the above-described (1) to the display control process according to the third example shown in the above-described (3).
The display control process according to this embodiment is not limited to the display control process according to the first example shown in the above-described (1) to the display control process according to the fourth example shown in the above-described (4). For example, the display control device according to this embodiment may perform, as the display control process according to this embodiment, a process for realizing an expression in which a display object which is displayed on the display surface is disposed as if it were in any of a plurality of display layers (hereinafter referred to as “multilayer expression”).
For example, the display control device according to this embodiment realizes the multilayer expression according to this embodiment by changing, for each display object, the transferring quantity of the display object in accordance with the detected movement of the display device according to this embodiment.
For example, the display control device according to this embodiment changes, for each display object, the transferring quantity of the display object in accordance with the detected movement based on properties set in the display object. Here, the properties set in the display object according to this embodiment show, for example, a level related to the transferring quantity according to the detected movement of the display device according to this embodiment, and show a display layer in which the display object is to be disposed among the plurality of display layers.
For example, the display control device according to this embodiment changes the moving quantity of the display object in accordance with the detected movement based on property information (data) in which properties corresponding to the display object are set.
Here, examples of the property information according to this embodiment include data including an adjustment coefficient to be multiplied by the moving quantity or the inclination quantity calculated based on the detected movement of the display device according to this embodiment. For example, when the property information according to this embodiment includes the adjustment coefficient, the display control device according to this embodiment multiplies the moving quantity or the inclination quantity calculated based on the detected movement of the display device according to this embodiment by the adjustment coefficient included in the property information to set the transferring quantity of the display object as a transferring quantity corresponding to the properties set in the display object.
The property information according to this embodiment is not limited to the above-described examples.
For example, the property information according to this embodiment may directly numerically represent the level related to the transferring quantity according to the detected movement of the display device according to this embodiment. When the property information according to this embodiment directly numerically represents the level related to the transferring quantity according to the detected movement of the display device according to this embodiment, the display control device according to this embodiment specifies the adjustment coefficient corresponding to the property information according to this embodiment using a table or the like in which numerical values representing the level related to the transferring quantity and the adjustment coefficients are associated with each other. In addition, for example, the display control device according to this embodiment multiplies the moving quantity or the inclination quantity calculated based on the detected movement of the display device according to this embodiment by the specified adjustment coefficient to set the transferring quantity of the display object as a transferring quantity corresponding to the properties set in the display object.
Here, for example, the properties corresponding to the display object according to this embodiment may be preset or set based on a user's operation. In addition, the properties corresponding to the display object according to this embodiment may be dynamically set by, for example, the display control device according to this embodiment or the display device according to this embodiment. Examples of the presetting of the properties include setting a display object, such as a clock which is displayed on the display surface or an icon which displays remaining battery power, which is assumed to be displayed constantly on the display surface to have properties corresponding to “the level representing that no transfer is made in accordance with the detected movement of the display device according to this embodiment.” In addition, examples of the dynamic setting of the properties corresponding to the display object according to this embodiment by the display control device or the like according to this embodiment include setting an icon corresponding to a mail application to have properties according to the number of mail items which are managed by the mail application.
For example, as described above, when the transfer quantity of the display object is changed for each display object in accordance with the detected movement of the display device according to this embodiment based on the properties set in the display object, the user seeing the transferring display object can feel as if the display object is disposed in a different display layer depending on the moving mode of the display object. Accordingly, for example, as described above, when the transferring quantity of the display object is changed for each display object in accordance with the detected movement of the display device according to this embodiment based on the properties set in the display object, the multilayer expression according to this embodiment can be realized.
The display control process according to the fifth example according to this embodiment is not limited to the process of changing the transferring quantity based on the properties set in the display object as described above. For example, the display control device according to this embodiment can also change, for each display object type, the transferring quantity of the display object in accordance with the detected movement of the display device according to this embodiment. Here, examples of the display object type according to this embodiment include icons corresponding to applications, thumbnail images, and web screens.
For example, the display control device according to this embodiment may display a display object of which the transferring quantity according to the detected movement is smaller in a smaller size.
On the other hand, the display control device according to this embodiment can also display a display object of which the transferring quantity according to the detected movement is larger in a larger size. Hereinafter, a second example of the display control process according to the fifth example according to this embodiment will be described using the case in which the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller in a smaller size as an example. For example, by performing a process similar to the following “process related to the case in which a display object of which the transferring quantity according to the detected movement is smaller is displayed in a smaller size,” the display control device according to this embodiment can realize display of a display object of which the transferring quantity according to the detected movement is larger in a larger size.
For example, using a table or the like in which transferring quantities and reduction coefficients for reducing the size of the display object are associated with each other, the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller in a smaller size. Needless to say, the process for displaying a display object of which the transferring quantity according to the detected movement is smaller in a smaller size in the display control device according to this embodiment is not limited to the above-described examples.
For example, as described above, when the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller in a smaller size, a user can feel as if the display object is disposed in a different display layer. Accordingly, for example, as described above, when the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller in a smaller size, the multilayer expression according to this embodiment can be realized.

For example, as shown in
For example, the display control device according to this embodiment may increase the transmittance of a display object of which the transferring quantity according to the detected movement is smaller.
On the other hand, the display control device according to this embodiment can also decrease the transmittance of a display object of which the transferring quantity according to the detected movement is larger. Hereinafter, a third example of the display control process according to the fifth example according to this embodiment will be described using the case in which the display control device according to this embodiment increases the transmittance of a display object of which the transferring quantity according to the detected movement is smaller as an example. For example, by performing a process similar to the following “process related to the case in which the transmittance of a display object of which the transferring quantity according to the detected movement is smaller is increased,” the display control device according to this embodiment can decrease the transmittance of a display object of which the transferring quantity according to the detected movement is larger.
For example, using a table or the like in which transferring quantities and transmittances of the display object are associated with each other, the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller with increased transmittance. Needless to say, the process for displaying a display object of which the transferring quantity according to the detected movement is smaller with increased transmittance in the display control device according to this embodiment is not limited to the above-described examples.
For example, as described above, when the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller with increased transmittance, a user can feel as if the display object is disposed in a different display layer. Accordingly, for example, as described above, when the display control device according to this embodiment displays a display object of which the transferring quantity according to the detected movement is smaller with increased transmittance, the multilayer expression according to this embodiment can be realized.
The display object according to this embodiment is not limited to the display object which is permitted to be transferred in accordance with the detected movement (which may hereinafter be referred to as a “first display object”). The display object according to this embodiment may include, for example, a display object which is not permitted to be transferred in accordance with the detected movement (which may hereinafter be referred to as a “second display object”).
Examples of the first display object according to this embodiment include a display object assigned to a local space (a coordinate system transferring along with the direction of the user on which the display device according to this embodiment is mounted). Specific examples of the first display object according to this embodiment include a display object of an operation system which can be operated by a user.
Here, the coordinates in the local space which represent the position of the first display object according to this embodiment are obtained from, for example, a relative angle (for example, indicating an angle at which the display device according to this embodiment is moved for a fixed time) of the display device according to this embodiment, which is calculated based on detection data acquired from the sensor, capable of detecting the movement of the display device according to this embodiment, of the display device according to this embodiment and acceleration shown by the acquired detection data.
In addition, examples of the second display object according to this embodiment include a display object assigned to a global space (a coordinate system having no changes along with the direction of the user on which the display device according to this embodiment is mounted). Specific examples of the second display object according to this embodiment include a display object serving as a marker for object recognition.
Here, the coordinates in the global space which represent the position of the second display object according to this embodiment are obtained from, for example, absolute angle (azimuth) information (data), position information (data) obtained through the Global Positioning System (GPS), and captured images (for example, captured images obtained by capturing the images of the front of the user on which the display device according to this embodiment is mounted, captured images obtained by capturing the movement of the user, and the like).
As described above, when the display object according to this embodiment includes the first display object and the second display object, for example, the display control device according to this embodiment transfers the first display object in accordance with the detected movement and does not transfer the second display object when the movement of the display device according to this embodiment is detected.
For example, as described above, when the display control device according to this embodiment transfers the first display object in accordance with the detected movement and does not transfer the second display object, a user can feel as if the display object is disposed in a different display layer. Accordingly, for example, as described above, when the display control device according to this embodiment transfers the first display object in accordance with the detected movement and does not transfer the second display object, the multilayer expression according to this embodiment can be realized.
Here,
First, A1 of
Next, B1 of
For example, as shown in
The display control process according to this embodiment is not limited to the display control process according to the first example shown in the above-described (1) to the display control process according to the fifth example shown in the above-described (5). For example, the display control device according to this embodiment can also display a display object when a predetermined condition is satisfied. Here, examples of the predetermined condition include occurrence of some event such as reception of new mail (in the case of an icon corresponding to the mail application).
For example, the display control device according to this embodiment displays a display object while changing the transmittance and size of the display object, convergence distance related to parallax, and the like. When the transmittance of the display object is changed, for example, the display control device according to this embodiment displays the display object with a change from a state in which the transmittance is high to a state in which the transmittance is low. When the size of the display object is changed, for example, the display control device according to this embodiment displays the display object with a change from a state in which the size is small to a state in which the size is large. When the convergence distance is changed, for example, the display control device according to this embodiment displays the display object with a change from a state in which the convergence point is adjusted to be distant from the user on which the display device according to this embodiment is mounted to a state in which the convergence point is adjusted to be close to the user.
For example, as shown in A1, B1, C1, and D1 of
(7) Seventh Example of Display Control Process According to Embodiment: Example of Process for Case in which Axial Direction According to Embodiment is Front-Back Direction of User on which Display Device According to Embodiment is Mounted
As described above, the axial direction according to this embodiment is not limited to the yaw direction, the pitch direction, and the roll direction, and may include a front-back direction of the user on which the display device according to this embodiment is mounted. When the axial direction according to this embodiment in which the movement is detected is the front-back direction of the user on which the display device according to this embodiment is mounted, the display control device according to this embodiment changes the display size of the display object from the reference size in accordance with the detected movement.
For example, as shown in A2, B2, C2, and D2 of
The expression realized by the display control process according to the seventh example is not limited to the example shown in
For example, when the display size of the display object is changed, the display control device according to this embodiment may change the changed display size of the display object to the reference size. After the display size of the icon is increased, the display size returns to the original display size (reference size) before the display size was increased when the above-described process is further performed.
For example, when display objects are disposed to surround a user on which the display device according to this embodiment is mounted, the user may not recognize whether the display object displayed on the display surface is a display object disposed at an end.
Therefore, the display control device according to this embodiment may change an interval between the display objects based on the position at which the display object is disposed and the detected movement of the display device according to this embodiment. The display control device according to this embodiment changes an interval between the display objects when, for example, the position of the display object is a position corresponding to the display object disposed at an end.
Here, the position at which the display object is disposed in the display control process according to the eighth example is represented by, for example, coordinates in a global space (a coordinate system having no changes along with the direction of the user on which the display device according to this embodiment is mounted).
Examples of the method of changing the interval between the display objects include increasing an interval between the display objects in accordance with the detected movement.
For example, as described above, when the display control device according to this embodiment changes the interval between the display objects, the user on which the display device according to this embodiment is mounted can visually recognize that the display object displayed on the display surface is a display object disposed at an end.
Here,
For example, as shown in A1, B1, and C1 of
The display control device according to this embodiment does not display a frame around the display surface when a display object is displayed on the display surface. In addition, for example, when there is a display object displayed in an end part of the display surface, the display control device according to this embodiment may further cause a fade-out expression of the display object by changing the transmittance of the end part of the display surface.
For example, as described above, when a frame is not displayed around the display surface or the fade-out expression of the display object is further caused, the display control device according to this embodiment can impart a floating feeling in which the display object floats in the air to a user on which the display device according to this embodiment is mounted.
For example, as shown in
The display control process in which the display control device according to this embodiment transfers a display object based on the detected movement of the display device according to this embodiment has been mainly described. However, the display control process in the display control device according to this embodiment is not limited to the process of transferring the display object based on the detected movement.
For example, when the movement of the display device according to this embodiment is not detected for a predetermined time, the display control device according to this embodiment may transfer the display object regardless of the movement of the display device according to this embodiment. Examples of the method of transferring the display object regardless of the movement of the display device according to this embodiment include randomly moving the display object around the reference position by the display control device according to this embodiment. Here, examples of the predetermined time related to the display control process according to the tenth example include a preset fixed time and a variable time which can be set through a user's operation or the like.
For example, when the movement of the display device according to this embodiment is not detected for a predetermined time and the display control device according to this embodiment transfers the display object regardless of the movement of the display device according to this embodiment as described above, the display control device according to this embodiment can realize an expression in which the display object gently moves when a user on which the display device according to this embodiment is mounted performs no operation for a predetermined time. In addition, for example, when transferring the display object regardless of the movement of the display device according to this embodiment as described above, the display control device according to this embodiment can impart, for example, a floating feeling in which the display object floats in the air to a user on which the display device according to this embodiment is mounted.
For example, when transferring the display object regardless of the movement of the display device according to this embodiment as described above, the display control device according to this embodiment may feed the state back to the user by, for example, outputting a sound (including music).
In addition, when transferring the display object regardless of the movement of the display device according to this embodiment as described above, the display control device according to this embodiment moves, for example, each transferring display object to a reference position when the movement of the display device according to this embodiment is detected. In this case, when the display control device according to this embodiment transfers each transferring display object to a reference position, for example, the display control device according to this embodiment can arrange the display objects which move gently.
When transferring the display object regardless of the movement of the display device according to this embodiment as described above, the display control device according to this embodiment may feed the state back to the user by, for example, outputting a sound (including music) when the movement of the display device according to this embodiment is detected.
For example, when the display surface has a state in which each icon is displayed at a reference position as shown in A1 of
For example, when displaying the icon as shown in B1 of
In addition, for example, the display control device according to this embodiment can arrange the display objects which move gently when, for example, transferring the icon transferred as shown in B1 of
The display control device according to this embodiment can also perform two or more of the display control process according to the first example shown in the above-described (1) to the display control process according to the tenth example shown in the above-described (10) in parallel. That is, for example, the display control device according to this embodiment can combine two or more of the display control process according to the first example shown in the above-described (1) to the display control process according to the tenth example shown in the above-described (10).
Next, an example of the configuration of the display control apparatus according to the present embodiment capable of performing the process relevant to the display control method according to the present embodiment described above will be described.
The display control apparatus 100 may include, for example, a read-only memory (ROM; not illustrated), a random access memory (RAM; not illustrated), a storage unit (not illustrated), an operation unit (not illustrated) operable by a user, and a display unit (not illustrated) that displays various screens as a display screen. In the display control apparatus 100, for example, the foregoing constituent elements are connected via a bus serving as a data transmission path.
Here, the ROM (not illustrated) stores a program used by the control unit 104 or control data such as a calculation parameter. The RAM (not illustrated) temporarily stores a program or the like executed by the control unit 104.
The storage unit (not illustrated) is a storage unit included in the display control apparatus 100 and stores, for example, data indicating display objects and various kinds of data such as applications.

The storage unit (not illustrated) may be detachably mounted on the display control apparatus 100.
An example of the operation unit (not shown) may be a later-described operation input device, for example, and an example of the display unit (not shown) may be a later-described display device, for example.
The MPU 150 is formed by, for example, an MPU or a various processing circuits and functions as the control unit 104 that controls the entire display control apparatus 100. For example, the MPU 150 serves as a display control unit 110 to be described below in the display control apparatus 100.
The ROM 152 stores a program used by the MPU 150, control data such as a calculation parameter, or the like. For example, the RAM 154 temporarily stores a program or the like executed by the MPU 150.
The recording medium 156 functions as a storage unit (not illustrated) and, for example, stores data indicating display objects or various data such as applications. Here, a magnetic recording medium such as a hard disk or a non-volatile memory such as a flash memory can be exemplified as the recording medium 156. Further, the recording medium 156 may be detachably mounted on the display control apparatus 100.
For example, the input and output interface 158 connects the operation input device 160 to the display device 162. The operation input device 160 functions as an operation unit (not illustrated) and the display device 162 functions as a display unit (not illustrated). Here, a Universal Serial Bus (USB) terminal, a Digital Visual Interface (DVI) terminal, a High-Definition Multimedia Interface (HDMI) terminal, and various processing circuits can be exemplified as the input and output interface 158. For example, the operation input device 160 can be provided on the display control apparatus 100 and is connected to the input and output interface 158 inside the display control apparatus 100. A button, a direction key, a rotation type selector such as a jog dial, or a combination thereof can be exemplified as the operation input device 160. For example, the display device 162 is provided on the display control apparatus 100 and is connected to the input and output interface 158 inside the display control apparatus 100. A liquid crystal display (LCD) or an organic electro-luminescence (EL) display (or called an organic light emitting diode (OLED) display) can be exemplified as the display device 162.
The input and output interface 158 is, of course, connected to an operation input device (for example, a keyboard or a mouse) which is an external device of the display control apparatus 100 or an external device such as a display device. For example, the display device 162 may be a device such as a touch screen in which a display process and a user's operation can be performed.
The communication interface 164 is a communication unit included in the display control apparatus 100 and functions as the communication unit 102 that performs wireless/wired communication with an external apparatus such as a display apparatus according to the present embodiment via a network (or directly). Here, a communication antenna, an RF circuit (wireless communication), an IEEE 802.15.1 port and a transmission and reception circuit (wireless communication), an IEEE 802.11b port and a transmission and reception circuit (wireless communication), or a LAN terminal and a transmission and reception circuit (wired communication) can be exemplified as the communication interface 164. A wired network such as a LAN or a wide area network (WAN), a wireless network such as a wireless local area network (WLAN) or a wireless wide area network (WWAN) via a base station, or the Internet using a communication protocol such as the transmission control protocol/internet protocol (TCP/IP) can be exemplified as the network according to the present embodiment.
The display control apparatus 100 has, for example, the configuration illustrated in
For example, the display control apparatus 100 may include a plurality of communication interfaces for which communication schemes differ or communication schemes are the same.
For example, when communication is performed with an external apparatus such as the display apparatus according to the present embodiment via an external communication device connected via the input and output interface 158 or the like, the display control apparatus 100 may not include the communication interface 164.
For example, when the display control apparatus 100 is configured to perform a process as a stand-alone apparatus (for example, when the display control apparatus 100 and the display apparatus according to the present embodiment are an integrated apparatus), the display control apparatus 100 may not include the communication interface 164.
The display control apparatus 100 may have a configuration in which the operation input device 160 or the display device 162 is not included.
Referring back to
Here, a communication antenna and an RF circuit or a LAN terminal and a transmission and reception circuit can be exemplified as the communication unit 102, but the configuration of the communication unit 102 is not limited to the foregoing configuration. For example, the communication unit 102 may have a configuration of a USB terminal and a transmission and reception circuit, which corresponds to any standard capable of performing communication or any configuration capable of performing communication with an external apparatus via a network.
The control unit 104 includes, for example, an MPU and serves to control the entire display control apparatus 100. The control unit 104 includes, for example, the display control unit 110 and serves to initiatively perform the process relevant to the display control method according to the present embodiment.
The display controller 110 serves to perform the display control process according to this embodiment in a leading manner and controls the display of a display object which is displayed on the display surface in the display device according to this embodiment (a display device which is mounted on a user so that a display surface is positioned ahead of the user). For example, the display controller 110 transfers and displays a display object which is displayed on the display surface from a reference position corresponding to the display object in accordance with the movement of the display device, and transfers and displays the transferred display object from the position after the transfer to the reference position.
In greater detail, for example, the display controller 110 performs any of the display control process according to the first example shown in the above-described (1) to the display control process according to the eleventh example shown in the above-described (11).
Here, when the display control device 100 and the display device according to this embodiment are separate devices, for example, the display controller 110 communicates with the display device according to this embodiment through the communication unit 102 (or an external communication device connected thereto; the same applies hereinafter) to perform the display control process according to this embodiment. In this case, for example, the display controller 110 transmits a display control signal corresponding to the result of the process (for example, a signal including data showing the display object, data showing the position at which the display object is to be positioned, a display control instruction, and the like) to the display device according to this embodiment through the communication unit 102 to control the display of a display object in the display device according to this embodiment.
