Abstract

PROBLEM TO BE SOLVED: To provide an information processing device enabling selection of an object by an easy operation.SOLUTION: An information processing device comprises an input device, a displacement detection unit, an object assigning unit, and a display control unit. The input device has a plurality of selection keys, and the displacement detection unit detects a displacement direction of the input device. The object assigning unit automatically assigns at least some objects on a display screen of a display device to the selection keys in accordance with the displacement direction of the input device. The display control unit executes a function associated with an object assigned to a depressed selection key.

Description

  The present invention relates to an information processing apparatus that accepts user input in accordance with movement of an input apparatus.

  In recent information processing apparatuses, GUI (Graphical User Interface) is frequently used. In this GUI, the user can cause the device to execute a function associated with the selected object by selecting an object (for example, an icon) displayed on the display screen. For example, when using a keyboard or the like, the cursor on the display screen is moved onto a desired icon using the cursor key and the enter key is pressed. In addition, an input operation can be performed using a pointing device (such as a mouse or a trackball) that specifies an input position or coordinates on the display screen. For example, when a mouse is used, after moving the cursor on the display screen to a desired icon, the icon is selected by left-clicking.

  In recent years, a remote control pointer in which a pointing function is added to a remote control device is known. With this remote control pointer, an icon is selected by pressing the enter button after the pointer on the display screen is moved onto a desired icon in accordance with the movement of the casing held by the user.

  In addition, for example, in Patent Document 1, after the pointer on the display screen is moved to the vicinity of a desired object by the direction button, the object around the pointer is assigned to each operation button. Each object is selected by pressing an assigned operation button.

JP 2008-269217 A

  However, for example, when using a keyboard or the like, the cursor key must be pressed many times until the icon is reached, and it is necessary to press the enter key for selection. Thus, it is troublesome because the number of key operations is very large. Also, when using a pointing device, if the display size of the icon is small or the display interval is narrow, it is difficult to accurately overlay the cursor on the icon, so that an erroneous operation is likely to occur. In particular, when a remote control pointer is used, it is easy to shake, so it is difficult for a user who is not used to move the pointer accurately. On the other hand, when the icon display size and the display interval are widened, there are problems such as restrictions on the layout and design of the display screen and deterioration of the appearance of the display screen.

  In Patent Document 1, since it is necessary to move the pointer to the vicinity of a desired object, the operation is not easy and troublesome. Further, if an operation is mistaken, a desired object may not be assigned to the operation button.

  The present invention has been made in view of such a situation, and an object thereof is to provide an information processing apparatus capable of selecting an object with an easy operation.

  In order to achieve the above object, an information processing apparatus according to an aspect of the present invention includes an input device having a plurality of selection keys, a displacement detection unit that detects a displacement direction of the input device, and a displacement direction of the input device. An object assigning unit that automatically assigns at least some objects on the display screen of the display device to the selection key, and a display control unit that executes a function associated with the object assigned to the pressed selection key; .

  According to the above configuration, at least some objects on the display screen of the display device are automatically assigned to the plurality of selection keys of the input device according to the displacement direction of the input device. When the selection key is pressed, a function associated with the object assigned to the pressed selection key is executed. Therefore, a desired object can be selected and its function can be executed by moving the input device and pressing a selection key. Therefore, an object can be selected with an easy operation.

  In the above configuration, a direction determining unit that determines the moving direction on the display screen corresponding to the displacement direction of the input device, and a position calculating unit that calculates the position of the designated point on the display screen that moves according to the movement of the input device; The object assigning unit may preferentially assign the object arranged in the moving direction with respect to the designated point to the selection key.

  According to this configuration, when the input device is moved, the object arranged in the movement direction corresponding to the displacement direction of the input device has priority over the designated point that moves according to the movement of the input device on the display screen. Assigned to the selection key. Therefore, the user can assign a desired object to the selection key with an easy operation.

  In the above configuration, the input device may further include an assignment key, and the object assignment unit may assign the object to the selection key according to the displacement direction of the input device only during a period in which the assignment key is pressed.

  According to this configuration, when the input device is moved by pressing the assignment key, at least a part of the objects on the display screen can be assigned to the selection key. On the other hand, if the assignment key is released, the selection key assignment state is maintained even if the input device is moved. Therefore, the user can assign an object to the selection key only during a desired period. Therefore, the operation can be made easier and more convenient.

  In the above configuration, the display control unit may display a display object indicating a selection key to which the object is assigned on or around the object on the display screen.

  According to this configuration, the display object indicating the assigned selection key can be displayed on or around the object on the display screen. Therefore, the user can easily recognize which object is assigned to which selection key.

  Furthermore, in the above configuration, the display control unit may delete the display object from the display screen when the assignment to the selection key by the object assignment unit is released.

  According to this configuration, it is possible to prevent the display screen from becoming difficult to see due to display of the display object.

  The above configuration may further include a switching unit that switches whether to activate the function of the object allocation unit in accordance with a specific user operation.

  According to this configuration, it is possible to switch whether to enable the function of the object assignment unit. Therefore, an object on the display screen can be assigned to the selection key in accordance with the convenience of the user.

  In the above configuration, when the displacement direction of the input device is newly detected while the object is assigned to the selection key, the object assignment unit displays the assignment to the selection key according to the newly detected displacement direction. Objects on the screen may be dynamically changed.

  According to this configuration, even if an object is already assigned to each selection key, the object assigned to the selection key changes dynamically if the displacement direction of the input device changes. Therefore, it is possible to easily assign a desired object to the selection key.

  In the above configuration, the displacement detection unit further detects the displacement speed of the input device, and when the displacement speed is equal to or greater than the threshold value, the object assignment unit assigns the object to the selection key according to the displacement direction of the input device. May be.

  According to this configuration, when the displacement speed of the input device is equal to or higher than the threshold value, the object on the display screen is assigned to the selection key. In other words, if the displacement speed is less than the threshold value, the object can be prevented from being assigned to the selection key. Therefore, malfunction can be prevented.

Embodiments of the present invention will be described below with reference to the drawings, taking the display control system 100 as an example.
<First Embodiment>

  FIG. 1 is an external view of a display control system. In the display control system 100 of FIG. 1, an STB (Set Top Box) 2 that receives a control signal based on a user input from a remote control pointer 1 is connected to a liquid crystal television 3 via an HDMI (registered trademark) cable 4. The remote control pointer 1 is an example of an input device, the STB 2 including the remote control pointer 1 is an example of an information processing device, and the liquid crystal television 3 is an example of a display device.

  In the following, a movement that displaces the direction of the remote control pointer 1 in the horizontal direction is referred to as yawing, and the movement direction is referred to as a yawing direction. In addition, the movement that displaces the direction of the remote control pointer 1 in the vertical direction is called pitching, and the movement direction is called the pitching direction. Further, the horizontal direction of the display screen 31 of the liquid crystal television 3 is called the X-axis direction, and the vertical direction is called the Y-axis direction. The origin of the (X, Y) coordinate position of the display screen 31 is not particularly limited, but is assumed to be the leftmost and uppermost position of the display screen 31. These items apply not only to FIG. 1 but also to other drawings.

  The STB 2 receives a control signal output from the remote control pointer 1 and performs an operation based on the received control signal. For example, it is assumed that a broadcast program channel to be displayed on the display screen 31 of the liquid crystal television 3 is designated by a user input received by the remote control pointer 1. In this case, the STB 2 extracts the broadcast signal of the designated channel and displays the broadcast program on the liquid crystal television 3.

  The STB 2 has a GUI (Graphical User Interface) function. The STB 2 selects an object on the display screen 31 based on a user operation received by the remote control pointer 1, and executes a process (for example, activation of a specific application) associated with the selected object. This operation will be described in detail later.

  Next, the configuration of the remote control pointer 1 and the STB 2 will be described in detail. FIG. 2 is a block diagram illustrating a configuration example of the remote control pointer and the STB.

  First, the remote control pointer 1 will be described. As shown in FIG. 2, the remote control pointer 1 includes a housing 10, an input unit 11, a sensor unit 12, a memory 13, a control circuit unit 14, a communication unit 15, a built-in antenna 16, and a power supply unit 17. And. The housing 10 is a housing in which each part of the remote control pointer 1 is mounted.

  The input unit 11 receives a user input and outputs an input signal based on the user input to the control circuit unit 14. The input unit 11 has a plurality of operation keys provided on the outside of the housing 10. FIG. 3 is a front view showing an arrangement example of operation keys of the remote control pointer. As shown in FIG. 3, the operation key of the input unit 11 includes a power key p1, function keys f1 to f3, a mode key m1, and nine select keys s1 to s9. The power key p1 is a power key for switching on / off the power of the remote control pointer 1. The function keys f1 to f3 are function keys used in combination with other operation keys (for example, select keys s1 to s9). The mode key m1 is a switching key for switching the input mode of the remote control pointer 1. As will be described later, when the mode key m1 is pressed, the input mode of the remote control pointer 1 is switched to the pointing mode or the cursor input mode. The select keys s1 to s9 are selection keys that are used in various ways depending on the input mode of the remote control pointer 1. Although nine select keys s1 to s9 are provided in FIG. 3, the number of select keys is not limited to the example of FIG.

  The sensor unit 12 is a displacement detection unit that detects a displacement speed and a displacement amount in each displacement direction including at least the yawing direction and the pitching direction (see FIG. 1) of the housing 10 of the remote control pointer 1. The sensor unit 12 includes an acceleration sensor 121 and a gyro sensor 122.

  The acceleration sensor 121 is a detection element that detects each acceleration acting in at least one direction. When the acceleration sensor 121 detects the gravitational acceleration acting vertically downward, the yawing direction and the pitching direction of the remote control pointer 1 can be defined using the vertically downward direction as a reference direction. The acceleration sensor 121 is not particularly limited. For example, a semiconductor acceleration sensor 121 can be used.

  The gyro sensor 122 is a detection element that detects at least the angular velocity and the amount of angular displacement in the yawing direction and the pitching direction according to the movement of the housing 10 of the remote control pointer 1. Note that by integrating the angular velocity detected by the gyro sensor 122 with time, the amount of angular displacement that the remote control pointer 1 has moved during the integration period can be obtained. The gyro sensor 122 is not particularly limited. For example, a mechanical, fluid, or optical angular velocity sensor can be used.

  The memory 13 is a non-volatile storage medium, and stores programs and control information used by each unit (particularly the control circuit unit 14) of the remote control pointer 1.

  The control circuit unit 14 controls each unit of the remote control pointer 1 using a program and control information stored in the memory 13. The control circuit unit 14 includes a communication control unit 141 that controls the communication unit 15.

  The communication unit 15 performs wireless communication with the STB 2 via the built-in antenna 16 using, for example, Bluetooth (registered trademark). For example, the communication unit 15 transmits a control signal including an input signal output from the input unit 11 and a detection signal output from the sensor unit 12.

  The power supply unit 17 is a small battery that supplies driving power to the control circuit unit 14 of the remote control pointer 1 and other components. Examples of the power supply unit 17 include, but are not limited to, a dry battery, a button-type battery, a lithium ion battery, and a lithium polymer battery.

  Next, STB2 will be described. As shown in FIG. 2, the STB 2 includes a tuner unit 21, an operation unit 22, a memory 23, a receiving unit 24, an input / output I / F 25, and a CPU 26. In addition, the STB 2 may include a storage device such as an HDD (Hard Disk Drive), an optical disk drive device, and the like.

  The tuner unit 21 selects a broadcast program of a preset channel from the broadcast signal transmitted from the antenna 21a, and outputs the broadcast signal after the channel selection to the CPU 26.

  The operation unit 22 is an input unit provided in the STB 2 and outputs an input signal based on the received user input to the CPU 26.

  The memory 23 is a non-volatile recording medium, and stores programs and control information used for each unit of the STB 2 (particularly the CPU 26). The memory 23 also stores display information of various objects to be displayed on the liquid crystal television 3, application programs and data associated with each object, and the like. The type of object is not particularly limited. For example, various types of content (text information, image information, audio information, etc.) and the structure (layout) and style when they are displayed can be handled as objects.

  The receiving unit 24 receives the control signal output from the remote control pointer 1 and outputs it to the CPU 26. Note that the receiving unit 24 is built in the STB 2 in FIG. 2, but may be a receiving device that is detachably connected to an interface (not shown) mounted on the STB 2.

  The input / output I / F 25 is a communication interface for the STB 2 to communicate with an external device, and includes a communication unit (not shown) compliant with the HDMI standard. As shown in FIG. 2, the input / output I / F 25 is connected to the HDMI cable 4 connected to the liquid crystal television 3.

  The CPU 26 controls each part of the STB 2 using a program and control information stored in the memory 23. The CPU 26 includes an image control unit 261, an audio control unit 262, a displacement conversion unit 263, a direction determination unit 264, a threshold determination unit 265, a position calculation unit 266, an object allocation unit 267, and a switching unit 268. , And a display control unit 269.

  The image control unit 261 generates an image signal based on the broadcast signal output from the tuner unit 21. The generated image signal is output from the input / output I / F 25 to the liquid crystal television 3, and an image based on the image signal is displayed on the liquid crystal television 3.

  The audio control unit 262 generates an audio signal based on the broadcast signal output from the tuner unit 21. The generated audio signal is output from the input / output I / F 25 to the liquid crystal television 3, and the audio based on the audio signal is output from a speaker (not shown) of the liquid crystal television 3.

  The displacement conversion unit 263 calculates the moving speed and moving distance of the pointer 32 on the display screen 31 according to the detection result of the sensor unit 12. The pointer 32 is a designated point on the display screen 31 that is specified based on a control signal output from the remote control pointer 1. For example, the control signal transmitted from the remote control pointer 1 includes a detection signal indicating an angular velocity and an angular displacement amount of at least the yawing direction and the pitching direction of the remote control pointer 1. The displacement conversion unit 263 calculates a moving speed component and a moving distance component of the pointer 32 in the X-axis direction on the display screen 31 based on the angular velocity and angular displacement amount in the yawing direction indicated by the detection signal. Similarly, the displacement conversion unit 263 calculates a moving speed component and a moving distance component of the pointer 32 in the Y-axis direction on the display screen 31 based on the angular velocity and the angular displacement amount in the pitching direction. Then, the displacement conversion unit 263 calculates the moving speed of the pointer 32 on the display screen 31 based on the moving speed components in the X-axis direction and the Y-axis direction, and the moving distance components in the X-axis direction and the Y-axis direction. Based on the above, the moving distance of the pointer 32 on the display screen 31 is calculated.

  The direction determination unit 264 determines the moving direction of the pointer 32 on the display screen 31 corresponding to the displacement direction of the remote control pointer 1 based on the calculation result of the displacement conversion unit 263 or the detection signal of the sensor unit 12. The direction determining unit 264 associates the yawing direction of the remote control pointer 1 with the X axis direction on the display screen 31 and associates the pitching direction of the remote control pointer 1 with the Y axis direction on the display screen 31.

  The threshold determination unit 265 determines whether the moving speed of the pointer 32 calculated by the displacement conversion unit 263 is equal to or higher than the speed threshold. Further, the threshold determination unit 265 further determines whether or not the movement distance of the pointer 32 calculated by the displacement conversion unit 263 is less than the distance threshold.

  The position calculation unit 266 calculates the coordinate position of the pointer 32 on the display screen 31 that moves according to the movement of the remote control pointer 1 based on the calculation result of the displacement conversion unit 263 or the detection signal of the sensor unit 12. The position calculation unit 266 may not calculate the coordinate position of the pointer 32 that moves in the movement direction when the threshold determination unit 265 determines that the movement distance of the pointer 32 is less than the distance threshold. By doing so, it is possible to prevent the pointer 32 from being erroneously moved due to the hand shake of the user holding the remote control pointer 1.

  The object assigning unit 267 automatically assigns at least some objects on the display screen 31 of the liquid crystal television 3 to the select keys S1 to S9 according to the moving direction of the pointer 32 (that is, the displacement direction of the remote control pointer 1). . This allocation process is performed when it is determined that the moving speed of the pointer 32 is equal to or higher than the speed threshold value in a state where the remote control pointer 1 is in the cursor input mode. For this reason, if the moving speed of the pointer 32 is less than the speed threshold, it is possible to prevent the object from being assigned to the selection key, thereby preventing malfunction. When it is determined that the moving speed of the pointer 32 is equal to or higher than the speed threshold and the moving distance is less than the distance threshold, it is desirable that the object allocation unit 267 does not execute the allocation process. By doing so, it is possible to prevent the pointer 32 from being erroneously moved due to the hand shake of the user holding the remote control pointer 1.

  In this allocation process, the object allocation unit 267 preferentially allocates objects arranged in the movement direction with respect to the pointer 32 to the select keys S1 to S9. Further, when the displacement direction of the remote control pointer 1 is newly detected in the state where the objects are assigned to the select keys S1 to S9, the object assigning unit 267 moves the object on the display screen 31 assigned to the select keys S1 to S9. Change. (Refer to FIG. 6A and FIG. 6B described later)

  The switching unit 268 switches whether to enable the function of the object allocation unit 267 according to a specific user operation. For example, the switching unit 268 switches the input mode of the remote control pointer 1 in response to pressing of the mode key m1.

  The display control unit 269 controls the display of the liquid crystal television 3. For example, the display control unit 269 causes the liquid crystal television 3 to display an object based on the display information stored in the memory 23. The display control unit 269 displays the display objects 34 a to 34 i on or around the object on the display screen 31 when the object allocation unit 267 performs the above-described allocation process. Display objects 34a to 34i indicate select keys S1 to S9 to which objects are assigned (see FIGS. 6A and 6B described later). When any one of the select keys S1 to S9 is pressed, the display control unit 269 executes a function associated with the object assigned to the pressed select key. On the other hand, when the assignment to the select keys S1 to S9 by the object assigning unit 267 is canceled, the display objects 34a to 34i indicating the select keys S1 to S9 are deleted from the display screen 31.

  Next, a process of selecting an object on the display screen 31 using the remote control pointer 1 and executing the function will be described using the Internet WEB display screen 31 as an example. FIG. 4 is an example of a display screen in the pointing mode. FIG. 5 is an example of a display screen in the cursor input mode.

  The remote control pointer 1 is switched between the pointing mode and the cursor input mode each time the mode key m1 is pressed. In the pointing mode, a pointer 32 is displayed on the display screen 31 as shown in FIG. The pointer 32 can be moved according to the movement of the remote control pointer 1. When a predetermined operation key (for example, select key s5) is pressed while the pointer 32 is moved onto a predetermined object (for example, “company information”), the object is selected. Then, processing associated with the object (for example, activation of a specific application) is executed. For example, in FIG. 4, a process of displaying a WEB page of “company information” is executed.

  When the mode key m1 is pressed in the pointing mode, the input mode of the remote control pointer 1 is switched to the cursor input mode. In the cursor input mode, as shown in FIG. 5, the pointer 32 is not displayed, and the cursor 33 is displayed on or around the selected object on the display screen 31. The cursor 33 can be moved in focus in the vertical and horizontal directions using the select keys s2, s8, s4, and s6. When a predetermined operation key (for example, select key s5) is pressed, the object on which the cursor 33 is displayed is selected, and the process associated with the object is executed.

  When the remote control pointer 1 is in the cursor input mode (FIG. 5), if the angular velocity of the remote control pointer 1 is quickly shaken so as to be equal to or higher than a certain threshold value, a pair of objects on the display screen 31 is placed on the select keys s1 to s9. Can be assigned in one correspondence. 6A and 6B show an example of a display screen on which object assignment processing has been performed. In FIGS. 6A and 6B, a thick solid arrow indicates the moving direction of the non-display pointer 32 that moves when the remote control pointer 1 is swung. This moving direction corresponds to the direction in which the direction is moved by shaking the remote control pointer 1. Further, an arrow outlined by a broken line indicates the position of the non-display pointer 32 immediately before the remote control pointer 1 is shaken.

  For example, when the remote control pointer 1 is swung upward in the pitching direction in the state of FIG. 5, the moving direction of the pointer 32 is determined to be the upward direction of the display screen 31 (negative Y-axis direction) as shown in FIG. 6A. . This moving direction is directed to the object “home” in FIG. 6A. Therefore, the object “home” is assigned to the select key s1, and objects near the object “home” are preferentially assigned to the select keys s2 to S9. Then, the display objects 34a to 34i are displayed on or around the objects assigned to the select keys s1 to S9.

  The method for selecting objects assigned to the select keys s2 to s9 is not particularly limited. As shown in FIG. 6A, the objects may be selected in the order of position relative to the top-priority object “Home”, or a group of objects lined up in the row direction or column direction with the top-priority object “Home” are preferential. It may be selected. Alternatively, an object arranged on the display screen 31 on the right side (in the positive X-axis direction) or clockwise relative to the object “home” may be preferentially selected, and vice versa. Alternatively, an object arranged on the display screen 31 above the object “home” (in the negative Y-axis direction) may be preferentially selected, or vice versa.

  Further, in the state shown in FIG. 6A, when the angular velocity of the remote control pointer 1 is quickly and greatly shaken so that the angular velocity is equal to or greater than a certain first threshold and the angle change amount is equal to or greater than a certain second threshold, objects assigned to the select keys s1 to s9 are displayed. Can be changed dynamically. For example, when the remote control pointer 1 is swung to the left in the yawing direction in the state of FIG. 6A, the moving direction of the pointer 32 is determined to the left direction (negative X-axis direction) of the display screen 31 as shown in FIG. 6B. The This moving direction is directed to the object “product information”. Therefore, the object “product information” is reassigned to the select key s1, and objects near the object “product information” are preferentially reassigned to the select keys s2 to S9. And the display position of each display object 34a-34i is also updated.

  Next, when one of the select keys s1 to s9 is pressed in the state of FIGS. 6A and 6B, the object assigned to the pressed select key is selected, and the process associated with the object is executed. . For example, when the select key s3 is pressed in the state of FIG. 6B, a process of displaying a “support” WEB page is executed.

  Note that after any of the select keys s1 to s9 is pressed, the state where the objects are assigned to the select keys s1 to s9 as shown in FIG. 6A or 6B may be maintained. Alternatively, the assigned state may be returned to the pointing mode (FIG. 4) or the cursor input mode (FIG. 5) without being maintained. It is possible to set in advance which state will occur after the select key is pressed.

  6A and 6B, when the remote control pointer 1 is not operated for a certain period of time, the state shown in FIGS. 6A and 6B may be maintained, but the pointing mode (FIG. 4) or the cursor input mode (FIG. 5) may be maintained. May be returned. This point can also be set in advance.

  The first embodiment has been described above. According to the first embodiment, the STB 2 including the remote control pointer 1 functions as an information processing device. The remote control pointer 1 has select keys s1 to s9 and a sensor unit 12 that detects the displacement direction of the remote control pointer 1. The STB 2 includes an object assignment unit 267 and a display control unit 269. The object assigning unit 267 automatically assigns at least some objects on the display screen 31 of the liquid crystal television 3 to the select keys s1 to s9 according to the displacement direction of the remote control pointer 1. The display control unit 269 executes a function associated with the object assigned to the pressed select key.

  According to this configuration, at least some objects on the display screen 31 of the liquid crystal television 3 are automatically assigned to the select keys s1 to s9 of the remote control pointer 1 according to the displacement direction of the remote control pointer 1. When any one of the select keys s1 to s9 is pressed, a function associated with the object assigned to the pressed select key is executed. Therefore, a desired object can be selected and its function can be executed by moving the remote control pointer 1 and pressing any one of the select keys s1 to s9. Therefore, an object can be selected with an easy operation.

  Further, according to the first embodiment, the STB 2 further includes a direction determining unit 264 and a position calculating unit 266. The direction determining unit 264 determines the moving direction on the display screen 31 corresponding to the displacement direction of the remote control pointer 1. The position calculation unit 266 calculates the position of the pointer 32 on the display screen 31 that moves according to the movement of the remote control pointer 1. The object allocation unit 267 preferentially allocates objects arranged in the movement direction with respect to the pointer 32 to the select keys s1 to s9.

  In this way, when the remote control pointer 1 is moved, the object arranged on the display screen 31 in the movement direction corresponding to the displacement direction of the remote control pointer 1 with respect to the pointer 32 that moves according to the movement of the remote control pointer 1. Are preferentially assigned to the select keys s1 to s9. Therefore, the user can assign a desired object to the select keys s1 to s9 with an easy operation.

  Further, according to the first embodiment, the display control unit 269 displays the display objects 34a to 34i indicating the select keys s1 to s9 to which the object is assigned on or around the object on the display screen 31. In this way, the display objects 34a to 34i indicating the assigned select keys s1 to s9 can be displayed on or around the object on the display screen 31. Therefore, the user can easily recognize which object is assigned to which select key.

  Further, according to the first embodiment, the display control unit 269 erases the display objects 34a to 34i from the display screen 31 when the assignment to the select keys s1 to s9 by the object assignment unit 267 is cancelled. In this way, it is possible to prevent the display screen 31 from becoming difficult to see due to the display of the display objects 34a to 34i.

  Further, according to the first embodiment, the STB 2 further includes the switching unit 268. The switching unit 268 switches whether to enable the function of the object assignment unit 267 in response to a specific user operation (for example, pressing the mode key m1). In this way, it is possible to switch whether to enable the function of the object assignment unit 267. Therefore, objects on the display screen 31 can be assigned to the select keys s1 to s9 according to the convenience of the user.

  In the first embodiment, it is assumed that the displacement direction of the remote control pointer 1 is newly detected in a state where objects are assigned to the select keys s1 to s9. In this case, the object assignment unit 267 dynamically changes the object on the display screen 31 assigned to the select keys s1 to s9 according to the newly detected displacement direction. In this way, even if the objects are already assigned to the select keys s1 to s9, if the displacement direction of the remote control pointer 1 is changed, the objects assigned to the select keys s1 to s9 are also dynamically changed. Therefore, it is possible to easily assign a desired object to the select keys s1 to s9.

Further, according to the first embodiment, the sensor unit 12 further detects the angular velocity of the remote control pointer 1. When the angular velocity is equal to or higher than the threshold value, the object assignment unit 267 assigns the object to the select keys s1 to s9 according to the displacement direction of the remote control pointer 1. In this way, when the angular velocity of the remote control pointer 1 is equal to or greater than the threshold value, the objects on the display screen 31 are assigned to the select keys s1 to s9. In other words, if the angular velocity is less than the threshold value, the object can be prevented from being assigned to the select keys s1 to s9. Therefore, malfunction can be prevented.
Second Embodiment

  Next, a second embodiment will be described. In the second embodiment, only during a period when a specific operation key provided on the remote control pointer 1 is pressed, at least some objects on the display screen 31 are selected by the select keys S1 to S9 according to the displacement direction of the remote control pointer 1. Assigned to. The rest is the same as in the first embodiment. Hereinafter, a configuration different from the first embodiment will be described. Moreover, the same code | symbol is attached | subjected to the structure part similar to 1st Embodiment, and the description is abbreviate | omitted.

  FIG. 7 is a front view showing another arrangement example of the operation keys of the remote control pointer. As shown in FIG. 7, the input unit 11 of the remote control pointer 1 further includes a focus key c. The focus key c is an assignment key for enabling execution of processing for assigning at least some objects on the display screen 31 to the select keys s1 to s9. For example, when the remote control pointer 1 is in the pointing mode (FIG. 4) or the cursor input mode (FIG. 5), it is assumed that the remote control pointer 1 moves while the focus key c is pressed. In this case, the object allocation unit 267 automatically performs allocation processing according to the moving direction of the pointer 32 (the displacement direction of the remote control pointer 1).

  On the other hand, even if the remote control pointer 1 moves while the focus key c is not pressed, the object assignment unit 267 does not perform assignment processing and maintains the assignment state of the select keys S1 to S9. Therefore, the user can assign objects to the select keys S1 to S9 only during a desired period. Therefore, user operation can be made easier and more convenient.

  The second embodiment has been described above. According to the second embodiment, the remote control pointer 1 further has a focus key c, and the object assignment unit 267 selects an object according to the displacement direction of the remote control pointer 1 only during a period when the focus key c is pressed. Assigned to keys S1 to S9. In this way, if the focus key c is pressed and the remote control pointer 1 is moved, at least some objects on the display screen 31 can be assigned to the select keys S1 to S9. On the other hand, if the focus key c is released, even if the remote controller pointer 1 is moved, the assignment state of the select keys S1 to S9 is maintained. Therefore, the user can assign objects to the select keys S1 to S9 only during a desired period. Therefore, the operation can be made easier and more convenient.
