Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an external configuration of a display device 10 according to an embodiment of the present invention. As shown in FIG. 1, the display device 10 is a wristband type display device that is a kind of wearable computer. Specifically, the display device 10 is a belt-like (band-like) display device formed of a deformable material such as bending or twisting. The display device 10 is wound around a user's arm 100 (the left arm's forearm portion in FIG. 1), and one end and the other end are connected using a mounting member (not shown) such as a fastener, whereby the arm 100 is connected. It is attached to. When worn on the arm 100, the display device 10 is annular.

  The display device 10 includes a display unit 13 that displays an image. The display unit 13 includes a display area 131 on the outer peripheral surface of the display device 10. The display area 131 has an extending direction in the direction of circling the arm 100 (that is, the direction around the arm) and is arranged to circulate the arm 100. Here, the display area 131 has a length corresponding to one round of the arm 100 in the arm rotation direction. Furthermore, the display device 10 includes a contact sensor 121 that is superimposed on the entire display area 131.

FIG. 2 is a plan view showing an external configuration of the display device 10. FIG. 2A is a plan view (indicated by an arrow II in FIG. 1) of the annular display device 10 in a direction penetrating the ring. FIG. 2B shows a plan view of the display area 131 arranged so that the extending direction is linear.
In order to define the position (absolute position) in the extension direction on the display area 131, positions A, B, C, and D are determined as shown in FIGS. The position A is a position in the 12 o'clock direction when viewed from the center O of the ring of the annular display device 10. The position A is located at the uppermost position in the vertical direction of the display area 131 when the display device 10 is worn on the arm 100 as shown in FIG. The position B is a position in the 3 o'clock direction when viewed from the center O. The position C is a position in the 6 o'clock direction when viewed from the center O. The position C is a position of one end and the other end in the extending direction of the display area 131 and is a position where the above-described mounting member is provided. The position D is a position in the 9 o'clock direction when viewed from the center O. The position D is located at the lowest position in the vertical direction of the display area 131 when the display device 10 is worn on the arm 100 as shown in FIG.

FIG. 3 is a block diagram illustrating a hardware configuration of the display device 10. As illustrated in FIG. 3, the display device 10 includes a control unit 11, a sensor unit 12, a display unit 13, a communication unit 14, and a storage unit 15.
The control unit 11 includes a microcomputer having an arithmetic processing device including a CPU (Central Processing Unit) and a main memory including a ROM (Read Only Memory) and a RAM (Random Access Memory). For example, the CPU controls each unit of the display device 10 by reading a program stored in the ROM or the storage unit 15 into the RAM and executing the program.

  The sensor unit 12 includes a sensor that detects the state of the display device 10. Here, the sensor unit 12 includes a contact sensor 121 and an acceleration sensor 122. The contact sensor 121 is a sensor that detects an operation that indicates a position on the display area 131. The contact sensor 121 detects a contact operation on the display area 131. The contact sensor 121 outputs an operation signal indicating a position indicated by an indicator (for example, a user's finger F shown in FIG. 1) to the control unit 11. The contact sensor 121 is configured using, for example, a capacitance type sensor, but may be configured using another type of sensor such as a resistive film type. Here, the acceleration sensor 122 is a triaxial acceleration sensor, and is a detection unit that detects the acceleration in the triaxial direction applied to the display device 10. The acceleration sensor 122 detects acceleration as a physical quantity indicating a change in the direction in which the display area 131 faces. The acceleration detected by the acceleration sensor 122 can also be referred to as a physical quantity corresponding to a change in the attitude of the display device 10. The acceleration sensor 122 also functions as a vibration detection unit that detects vibrations acting on the display unit 13 (that is, the display device 10).

  The display unit 13 is configured using a liquid crystal display, for example, and displays an image in the display area 131. The communication unit 14 includes, for example, a wireless communication circuit and an antenna, and is an interface for communicating with an external device. The communication unit 14 performs wireless communication based on, for example, Bluetooth (registered trademark), but may perform communication of other methods. The storage unit 15 is a storage device such as an EEPROM (Electronically Erasable and Programmable ROM) or a flash memory. The storage unit 15 stores, for example, a control program executed by the control unit 11 and various application programs.

FIG. 4 is a diagram illustrating a home screen of the display device 10. Hereinafter, when explaining the screen displayed in the display area 131, the plan view described in FIG. 2 is used. In FIG. 4 and the like, the thickness of the display area 131 is expressed to be easy to understand the position of the image displayed in the display area 131. When the annular display device 10 is viewed in plan in the direction through which the ring penetrates, the object currently displayed in the display area 131 is not observed or hardly observed by the user.
While the home screen is displayed, the display device 10 displays each of the objects W1, W2, and W3. Each of the objects W1 to W3 is an object that can be operated by the user, and is, for example, an icon (for example, an application program icon) or a window (for example, a widget window). Each of the objects W1 to W3 (first object) is associated with a specific function in advance. Here, the object W1 is associated with a clock function. The object W2 is associated with a mailer (mail function). The object W3 is associated with a stock price display function for displaying the stock price in real time. Like the objects W1 and W2 illustrated in FIG. 1, the object is an image that visually represents an associated function, for example.

As shown in FIG. 1, the object W <b> 1 is displayed at a position including the position A (that is, the position at 12 o'clock) when the display device 10 is worn on the arm 100. The object W2 is displayed at a position including the position B (that is, the 3 o'clock position). The object W3 is displayed at a position including the position D (that is, the 9 o'clock position). For the user, in general, the object W1 is most easily observed, and then the objects are easily observed in the order of the objects W2 and W3.
Note that the number of objects displayed on the home screen and the functions associated with the objects may be set and changed by the user of the display device 10. For example, the object may be associated with each function such as an SNS (Social Networking Service), a game function, a function for displaying a weather forecast and news, and a browser. In addition, the object here is a rectangle (including a square), but may be another shape such as a circle.

  The display device 10 is characterized by a display operation for displaying an object. In the display operation of the object performed by the display device 10, the background area where the object is not arranged in the display area 131 is the first medium (for example, liquid), and the area where the object is arranged is the second medium (for example, gas (bubble) )), Based on the behavior of the second medium when the display area 131 is regarded as a container enclosing the first medium.

Next, functions related to display operations realized by the display device 10 will be described.
FIG. 5 is a functional block diagram illustrating a functional configuration of the control unit 11 of the display device 10. As illustrated in FIG. 5, the control unit 11 of the display device 10 realizes functions corresponding to the display control unit 111, the operation reception unit 112, and the execution unit 113 by executing a control program.
The display control unit 111 controls the display unit 13 to display an image in the display area 131. The display control unit 111 controls display of an object based on a change in the direction in which the display area 131 detected by the acceleration sensor 122 is directed. For example, when the direction in which the area where the object being displayed is directed is changed, the display control unit 111 changes the display position of the object to a position where the change in the direction in which the area is directed is reduced. For example, the display control unit 111 makes the display position of the object expressed by the direction of the hour hand of the clock constant regardless of the change in the direction in which the display area 131 faces. Thereby, even when the arm 100 rotates in the direction around the arm, the display position of the object viewed from the user is constant.
In addition to this, the display control unit 111 changes the display position of the object or changes the object to be displayed based on the operation received by the operation receiving unit 112.

The operation reception unit 112 receives an operation (here, a contact operation) for instructing a position on the display region 131 based on an operation signal supplied from the contact sensor 121.
When the display device 10 has a physical key or other operation element, the operation reception unit 112 may receive an operation using the operation element.

  The execution unit 113 executes a function associated with the object displayed in the display area 131. For example, when the operation reception unit 112 receives an operation of selecting an object being displayed, the execution unit 113 executes an application program associated with the object. However, the function executed by the execution unit 113 may not be a function involving execution of an application program.

  Next, the operation of the display device 10 will be described. Characteristic operations of the display device 10 are (A) basic operation of object display, (B) operation of changing the display position of the object, (C) operation at the time of selecting the object, and (D) weighting to the object. And (E) function execution operation.

(A) Basic Operation of Object Display FIG. 6 is a flowchart showing the basic operation of object display performed by the display device 10. FIG. 7 is a diagram for explaining the basic operation of object display. It is assumed that the control unit 11 of the display device 10 displays the home screen described in FIG.
During the display of the home screen, the control unit 11 detects a change in the direction in which the display area 131 faces based on the detection result of the acceleration sensor 122 (step SA1). And the control part 11 pinpoints the display position of an object based on the change of the detected direction (step SA2). And the control part 11 displays an object in the display position specified in the display area 131 (step SA3).

  For example, consider the case where the display device 10 is rotated 30 degrees clockwise from the state shown in FIG. 4 to the state shown in FIG. In this case, position A is at 1 o'clock, position B is at 4 o'clock, position C is at 7 o'clock, and position D is at 10 o'clock. At this time, the control unit 11 displays the object at a display position obtained by rotating the object by 30 degrees counterclockwise. That is, the control unit 11 displays the object W1 at the 12 o'clock position, displays the object W2 at the 3 o'clock position, and displays the object W3 at the 9 o'clock position. Further, consider the case where the display device 10 is rotated 30 degrees counterclockwise from the state shown in FIG. 4 to the state shown in FIG. 7B. In this case, position A is at 11:00, position B is at 2 o'clock, position C is at 5 o'clock, and position D is at 8 o'clock. At this time, the control unit 11 displays the object at a display position obtained by rotating the object by 30 degrees clockwise. That is, the control unit 11 displays the object W1 at the 12 o'clock position, displays the object W2 at the 3 o'clock position, and displays the object W3 at the 9 o'clock position.

  As described above, when the display device 10 is in a posture rotated by θ degrees (0 <θ <360) in one direction around the arm 100, the control unit 11 has θ degrees (that is, −−) in the opposite direction. The object is displayed at the display position rotated by θ degrees. As a result, even when the arm 100 rotates in the direction around the arm and the direction in which the display area 131 faces changes, the display position of each object viewed from the user is constant. The basic operation of this object display is based on the behavior that when the bubble, which is the second medium, is present in the liquid, which is the first medium, the second medium rises due to the specific gravity relationship between the two. ing. According to this basic operation of object display, the apparent position of each object is constant regardless of the rotation of the arm 100 in the direction around the arm, so that the user can easily observe the object being displayed.

(B) Object Display Position Changing Operation FIG. 8 is a flowchart showing an object display position changing operation performed by the display device 10. FIG. 9 is a diagram illustrating an operation for changing the display position of an object.
According to the basic operation of the object display performed by the display device 10, the position of each object on the display device 10 viewed from the user does not change even when the arm 100 rotates in the direction around the arm. However, there are cases where the user wants to temporarily change the display position of a specific object. For example, since the object W3 described in FIG. 4 is always displayed in the 9 o'clock direction, the user may want to move it to a position where he can easily observe it.
Therefore, the control unit 11 specifies a background area in the display area 131 and accepts an operation for moving the background area (step SB1). Here, as illustrated in FIG. 9A, the control unit 11 receives an operation (see an arrow) for moving the finger F in the clockwise direction while touching the background region with the contact sensor 121.

Next, the control part 11 specifies the display position of an object based on the received operation (step SB2). Then, the control unit 11 displays the object at the specified display position in the display area 131 (step SB3).
As shown in FIG. 9B, the control unit 11 moves the object being displayed in the direction in which the background area has moved by the distance that the background area has moved. For example, when the finger F moves by a quarter of the display area 131, the control unit 11 moves the object W3 from the position D to the position A (that is, the 12 o'clock position), and moves the object W1 from the position A. The object W2 is moved from position B to position C (ie, 6 o'clock position). For this reason, the user can easily observe the object W3 displayed at the 12 o'clock position.

Returning to FIG. 8, the control unit 11 determines whether or not the operation on the display area 131 is completed (step SB4). If the finger F remains in contact with the contact sensor 121, the control unit 11 determines that the operation on the display area 131 has not ended (step SB4; NO), and returns to the process of step SB1. On the other hand, when the finger F has moved away from the contact sensor 121, the control unit 11 determines that the operation on the display area 131 has ended (step SB4; YES). And the control part 11 returns the display position of an object to the display position before the operation received by the process of step SB1 (step SB5).
Here, the control part 11 returns to the display position demonstrated in Fig.9 (a), and displays each object. At this time, the control unit 11 may control the display of each object and the background area so that each object gradually returns to the original display position while moving. In addition, since the control unit 11 moves two or more objects being displayed (moves at the same time here), compared to the case where the objects are moved one by one as in the conventional touch panel operation, the burden on the user's operation is reduced. Decrease.
The operation of changing the display position of these objects is based on the behavior that the bubbles that are the second medium move so as to be pushed by the first medium as the liquid that is the first medium moves. Yes.

(C) Operation during Object Selection Operation FIG. 10 is a flowchart illustrating an operation during object selection operation performed by the display device 10. FIG. 11 is a diagram for explaining an operation during an object selection operation.
When the control unit 11 of the display device 10 receives an operation of selecting an object that is being displayed in the display area 131 and is associated with a plurality of functions (step SC1), the control unit 11 is associated with each function of the plurality of functions. The object is displayed in the display area 131 (step SC2). For example, when the object W1 shown in FIG. 11A is selected with the finger F, the control unit 11 displays the objects W11, W12, W13, and W14 (second objects) corresponding to the object W1 in the display area 131. Display. Since the object W1 is associated with the clock function, the objects W11 to W14 are associated with, for example, a time adjustment function, a function for displaying the current time in another country, and the like. The objects W11 to W14 are arranged along the user's arm 100 in the display area 131. When the control unit 11 receives an operation of selecting any of the objects W11 to W14, the control unit 11 executes a function associated with the selected object.

Even during display of the objects W11 to W14, the control unit 11 may perform the display control described in the sections “(A) Basic operation of object display” and “(B) Change operation of display position of object”. .
Note that the control unit 11 also arranges the objects in the display area 131 based on the functions of the plurality of functions associated with the selected object even when an operation for selecting the object W2 or W3 is received.

(D) Operation Regarding Weighting on Object FIG. 12 is a flowchart showing an operation regarding weighting on an object performed by the display device 10. FIG. 13 is a diagram illustrating an operation related to weighting for an object.
When a plurality of objects are arranged in the display area 131, it is desirable that the plurality of objects are arranged in consideration of convenience for the user. Therefore, the control unit 11 gives a weight value to the displayed object, and arranges the objects according to the given weight value.

First, the control unit 11 gives a weight value to each object being displayed according to a predetermined rule (algorithm) (step SD1). Next, the control unit 11 specifies the display position of the object based on the calculated weight value (step SD2). Next, the control unit 11 displays the object at the display position specified in the display area 131 (step SD3). For example, the control unit 11 displays the object having the maximum weight value at the 12 o'clock position, displays the objects in the order of the weight value in the clockwise direction from 12:00 to 6 o'clock, and further counterclockwise from 12:00. The objects are displayed in the order of the weight values in the 6 o'clock direction. In the example of FIG. 13A, the weight values are larger in the order of the objects W3, W1, and W2.
Note that the relationship between the weight value and the display position is not limited to this example.

Here, a specific example of the weight value will be described. (I) The importance level control unit 11 increases the weight value for an object having a higher importance level. For example, the control unit 11 increases the importance of an object associated with a function with push-type communication higher than the importance of an object associated with a function without push-type communication. This is because it is presumed that an object having a function with push communication is easier to be observed by the user than other objects.
The control unit 11 may determine the importance of the object based on the presence / absence of a specific process (for example, data update) other than the push-type communication. Moreover, the control part 11 may give a weight value according to the importance designated by the user for each object or function, or the importance designated at the design stage. The importance of the object may be determined based on any rule.

(II) Latest update date and time The control unit 11 increases the weight value of an object having a function that is closer to the latest update date and time of data update. For example, when an object is associated with a function involving data update, such as a mailer or stock price display function, it is assumed that the function with the latest update date and time of data update is more easily operated or observed by the user. For this reason, the control unit 11 increases the weight value for an object having a function that is closest to the latest update date and time.

(III) Update Frequency The control unit 11 increases the weight value for a function object having a higher data update frequency (that is, update frequency). The update frequency is, for example, the number of data updates per unit time. When an object is associated with a function that accompanies data update, it is presumed that the object is more easily observed by the user as the function is updated more frequently. For this reason, the control part 11 enlarges a weight value, so that the object of a function with a high update frequency is high.
Note that the update frequency may be fixed or may be changed by the user.

(IV) Active State / Inactive State The control unit 11 increases the weight value when the function associated with the object is in the active state, compared to the case of the inactive state. For example, it is assumed that the function in the active state is easier for the user to observe and manipulate the object than the function in the inactive state.
The control unit 11 may calculate the weight value by combining two or more of the above (I) to (IV), or may calculate the weight value based on another condition. The weight value is, for example, a value predetermined in the design stage (for example, (I) importance), a value indicating the execution state of the function (for example, (II) latest update date / time or (IV) active state / inactive state) , And a value set by the user (for example, (I) importance or (III) update frequency).

In the process of step SD3, the control unit 11 may change the size of the object according to the weight value. For example, as shown in FIG. 13B, the control unit 11 increases the display size of the object as the weight value increases. Here, the control unit 11 changes the display size of the object by changing the length of the display area 131 in the extension direction.
The operation related to the weighting on the object is based on the behavior of each second medium when the specific gravity of each of the plurality of second media is regarded as a weight value.

(E) Function Execution Operation FIG. 14 is a flowchart showing a function execution operation performed by the display device 10. FIG. 15 is a diagram for explaining the function execution operation. Before the operation described below, the control unit 11 is assumed to display objects W11 to W14 in the display area 131 as shown in FIG.
Based on the detection result of the acceleration sensor 122, the control unit 11 detects vibration (for example, an operation of shaking the display device 10) that has acted on the display device 10 (step SE1). In this case, the control unit 11 displays the updating image in the entire display area 131 (step SE2). The updating image is an image determined by the object being displayed. An updating image IM shown in FIG. 15B shows a state where the objects W11 to W14 are regarded as the second medium, the background region is regarded as the first medium, and the first medium and the second medium are mixed. This is a simulated image. However, the updating image may be another image as long as the image is determined by the object being displayed. And the control part 11 displays a home screen on the display area 131, as shown in FIG.15 (c) (step SE3).
In the process of step SE3, the control unit 11 may execute a function other than the function of displaying the home screen. For example, the control unit 11 may perform data update for bringing the function associated with the object being displayed to the latest state.

According to the display device 10 of the embodiment described above, even when the direction in which the display area 131 faces changes, it is possible for the user to easily observe the object being displayed.
Further, the display device 10 moves the object in accordance with an operation for moving the background area, and when the operation is completed, returns the object to the original display position. Further, the display device 10 displays the objects in the display area 131 in an array corresponding to the weight values given to the objects. Further, when detecting a vibration, the display device 10 displays a currently updated image in the display area 131 and then executes a predetermined function. That is, the display device 10 controls the display of an object based on the behavior of the second medium in the first medium. For this reason, according to the display device 10, it is possible to provide a user interface that makes it easy for the user to perform an intuitive operation on the object and can give the user a visual interest.

[Modification]
The present invention can be implemented in a form different from the above-described embodiment. The present invention can also be implemented in the following forms, for example. Further, the following modifications may be combined as appropriate.
(Modification 1)
Like the objects Wa and Wb shown in FIG. 16, the display device 10 may arrange the objects in the display area 131 along a direction (here, an orthogonal direction) that intersects the extension direction (that is, the direction around the arm). . This array of objects is also along the user's arm 100. In combination with the arrangement of the embodiment described above, the display device 10 may arrange the objects along each of the two directions along the arm 100.

  Further, the display device 10 may arrange the objects along a direction not along the user's arm 100. For example, as illustrated in FIG. 17A, the display device 10 has a thickness (width) in a direction away from the user's arm 100. In addition to the display area 131, the display device 10 includes a display area 131 a that intersects (for example, intersects with) the display area 131. The display area 131 and the display area 131a do not need to be physically separated. For example, a curved display area may be divided into the display area 131 and the display area 131a.

Under this configuration, the control unit 11 uses the display area 131 a to arrange the objects along a direction not along the user's arm 100, that is, along a direction away from the arm 100. For example, in the display area 131a including the position A, the control unit 11 arranges the objects Wc and Wd in order along the direction away from the arm 100. Furthermore, the display position of the objects arranged in the direction away from the arm 100 may be changed according to the operation performed by the finger F on the display area 131. In the example illustrated in FIG. 17B, the control unit 11 switches the display positions of the object Wc and the object Wd.
Further, the display device 10 may arrange the objects along each of three directions in total, including two directions along the user's arm 100 and a direction not along the user's arm 100.

(Modification 2)
In the embodiment described above, the display device 10 changes the display position of the object so that the display position viewed from the user is constant even when the arm 100 rotates in the direction around the arm. The display device 10 is not limited to this example, and the display device 10 may change the object to a display position that reduces the change in the direction when the direction in which the region in which the object is arranged is changed. Even in this case, since the change in the direction in which the area where the object is displayed is small with respect to the change in the posture of the arm 100, the user can easily observe the object.

(Modification 3)
The function associated with the object is not limited to the function described in the above embodiment. For example, the object may be associated with a folder for classifying electronic data (electronic file). In this case, the control unit 11 displays an object (for example, an icon) associated with the electronic data under the folder in accordance with an object selection operation associated with the folder being displayed.

(Modification 4)
In the above-described embodiment, the object display operation has been described using the home screen of the display device 10 as an example. The display device 10 is not limited to the home screen, and the display device 10 may perform the object display operation described in the above-described embodiment when displaying a predetermined screen accompanied by the display of the object.

(Modification 5)
In “(B) Operation for Changing Display Position of Object”, display device 10 has moved all objects being displayed together with the background area. Instead of this, the display device 10 may move only some objects related to the object instructed by the user. For example, the display device 10 may move an object instructed by the user and an object associated with a function having a common category.

(Modification 6)
The display device of the present invention is not limited to the wristband type display device, and may be a display device of another form that is used by being worn on the user's arm. As an example of this display device, there is a wristwatch type display device worn on a user's arm. The wristwatch-type display device 10 includes a display unit 13 and a mounting unit physically connected to the display unit 13. The mounting portion is a band-shaped (strip-shaped) member corresponding to a watch band. The display unit 13 is mounted on the arm 100 when the mounting unit is wound around the user's arm 100.
In addition, the display area 131 may be a display area having a shorter dimension than the circumference of the arm 100 or may not be a display area having an extension direction.

Further, the display device of the present invention is not limited to the display device worn on the user's arm, and may be a display device used by being held (that is, held in the hand) by the user. As an example of this type of display device, there is a display device such as a smartphone or a tablet terminal. Even in a display device that is used by being held by a user, it is possible to suppress the difficulty of observing a specific object by reducing the change in the display position of the object viewed from the user.
In addition, the display device of the present invention may be a display device that is mounted or held on a part of the user's body other than the hand such as an arm.
In addition, the sensor unit 12 may include a sensor other than the acceleration sensor 122 as long as it can detect a change in the direction in which the display area 131 faces. Further, the sensor unit 12 may be configured not to include the contact sensor 121.

(Modification 7)
A part of the configuration of the above-described embodiment may be omitted. For example, in the display device 10, “(B) Object display position change operation”, “(C) Object selection operation”, “(D) Object weighting operation”, and “(E) Function execution”. One or more of the “operations” may be omitted.
