Embodiment 1
<Outline of Embodiment 1>
The display device of the present embodiment is characterized in that it can generate cursor information for displaying a cursor that also serves as a direction display.

<Configuration of Embodiment 1>
FIG. 1 shows an example of functional blocks in the present embodiment. The “display device” (0100) of the present embodiment includes a “display” (0101) and a “cursor information generation unit” (0102).

  Each unit, which is a component of the present invention, is configured by either hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, hardware composed of a CPU, a memory, a bus, an interface, a peripheral device, and the like, and software executable on the hardware are listed. be able to. Specifically, the functions of the respective units are realized by sequentially executing the programs developed on the memory, by processing, storing, and outputting data on the memory and data input via the interface. (Same throughout this specification).

  The “display device” (0100) refers to a device for displaying a cursor in a portable electronic device such as a mobile phone, a PDA (Personal Digital Assistant), a navigation device, and a portable PC. The “cursor” is used to indicate the operation position and operation target when performing operations within the display of an electronic device. Select a mark or icon indicating the input position when inputting characters on the display. This refers to a selection frame such as an arrow or a character. FIG. 2 shows an example of the cursor. (1) and (2) are cursors indicating the input position by blinking or the like when inputting characters. Reference numerals 0201 and 0203 indicate cursors that are turned on, and reference numerals 0202 and 0204 indicate that the cursors are turned off. (3), (4), and (5) are examples of pointers such as arrows for selecting icons. (6) is a cursor (0205) indicating the position of the line being worked on. (7) is an example of a selection frame (0206) for selecting a character string by inverting the character string and the background or changing the background color. The cursor is generated in a cursor information generation unit (0102), which will be described later, and displayed on the display (0101) by the GUI configuration unit (0110).

  The “display” (0101) displays a GUI (Graphical User Interface). “GUI” refers to a user interface that uses a lot of graphics for displaying information to the user and can perform basic operations with a pointing device such as a mouse. By providing the program for using the GUI by the OS of the electronic device that uses the GUI, it is possible to unify the operational feeling of the application software. Normally, the GUI manager receives information for displaying data selected by the application program. Then, by outputting the received information to the display driver, an image generated with the information is displayed on the display.

  The display of the present invention is not particularly limited as long as it can display a GUI. For example, various liquid crystal displays, EL displays, plasma displays, and the like that can be used for portable devices can be used. For example, in the case of a liquid crystal display, TFT (Thin Film Transistor) liquid crystal, STN (Super Twisted Nematic) liquid crystal, etc. are mentioned. Further, the display on the display and the use of the program are not particularly limited. There is no need to display an application for generating additional information for direction display described later, and a browser screen or the like may be displayed. Two or more programs may be used simultaneously. In this case, it does not matter which program displays on the display.

  The “cursor information generation unit” (0102) is configured to generate cursor information that also serves as a direction display that can be used in the GUI according to the provision information. “Cursor information” refers to information for displaying a cursor used in the GUI, and refers to information that determines the position, size, form, color, and the like of the cursor. “Cursor information that also serves as direction display” refers to information for displaying a cursor that can perform direction display. “Direction display” is a display for indicating the direction of travel, direction, and the like. That is, the cursor information that also serves as a direction display can indicate the direction by the position, size, form, color, etc. of the cursor, and also exhibits the function of pointing the character, icon, etc. on the original display of the cursor Information to display a possible cursor. The cursor information generation unit generates such cursor information according to the provision information. “Granting information” refers to various information that can be used to generate cursor information. The assigned information always includes information for displaying a direction, and further includes information from an application using a cursor. Information from an application that uses a cursor refers to information for displaying an original cursor that does not have a direction display function. The cursor information generation unit can change and display the cursor on the displayed application based on the information related to the direction display from the non-displayed application. Note that the direction of the arrow on the display changes depending on the direction of the display, so it does not indicate the direction on the fixed map, but is given information that can display the direction based on the absolute direction. It is desirable that the cursor information is generated accordingly. The absolute direction can be measured by using a geomagnetic sensor or the like.

  An example of a conventional cursor display method will be described with reference to FIG. First, a case where an application (APP, 0303) is started on the OS (0301), displayed on the display, and executed will be described. When the cursor information generation unit (GUI configuration unit, 0302) acquires the information of the cursor (0305) from a mouse driver or the like, the cursor information generation unit (GUI configuration unit, 0302) outputs the information to the APP. The information to be acquired corresponds to, for example, cursor position information. The “GUI configuration unit” is a configuration for displaying a GUI on a display, and includes a circuit for displaying the GUI, software, and the like. The cursor information generation unit is a part of the GUI configuration unit, and generates information related to the cursor among the GUI displayed on the display. The APP that has received the information acquired from the mouse driver or the like calls a predetermined function F (0304) from the OS (0301) according to the cursor change program. The APP executes the called function and outputs the calculation result to the cursor information generation unit again. For example, a function that associates position information with the form of the cursor is called. If the position information indicates that the cursor form should be changed, a result that the cursor form is changed is output to the GUI configuration unit. The GUI configuration unit displays a cursor (0305) based on the received result.

  An example of a cursor generation method using the present invention will be described with reference to FIG. Normally, the application a (APPa, 0403) performs processing for displaying the cursor using the function Fa (0405) called from the OS (0401) as described in FIG. The cursor (0407) is displayed. At this time, it is assumed that the application b (APPb, 0404) that can indicate the traveling direction (0408) as in (2) is executed without being displayed on the display. In APPb as well, processing related to direction display is performed using the function Fb (0406), and the result is output to the GUI configuration unit (0402). The processing result from APPa and the processing result from APPb correspond to the assignment information. The GUI configuration unit generates cursor information for generating a cursor used in APPa based on the processing result from APPa and the processing result (append information) from APPb. By displaying the generated cursor information on a display via a display driver, a cursor (0409) that also serves as a direction display can be displayed as shown in (3).

The grant information may be acquired from the outside by means of communication or the like, or may be generated and acquired within the display device. Further, the grant information is not limited to one, and may be two or more grant information. When the given information is two or more, it may be information acquired from the same program or information acquired from another program. The cursor information generation unit can generate cursor information corresponding to the provision information by holding a table in which the provision information and the cursor information are associated with each other as shown in FIG. For example, the flow of acquiring the grant information b and generating the cursor information 2 when the grant information is information indicating the direction and the cursor information is information for determining the direction indicated by the arrow cursor will be described with reference to FIG. To do. As the added information b, information for indicating northeast as shown in FIG. 6A (angle from the center position, 0601) and the position of the cursor on the display from the mouse driver (tip coordinates of the cursor arrow, 0602) Is acquired as the cursor information 2, the cursor information for generating a cursor in which the tip of the arrow points to the northeast as shown in (2). Specifically, information giving the tip coordinates (x ₁ , y ₁ ) and root coordinates (x ₂ , y ₂ ) of the cursor on the display is generated as the cursor information. Note that, as illustrated in FIG. 5, the assignment information and the cursor information may not have a one-to-one correspondence.

  FIG. 7 is a diagram illustrating an example of a hardware configuration of the display device according to the present embodiment. The operation of the display device that generates cursor information in accordance with the assigned information will be described with reference to FIG. The display device of this embodiment includes “CPU” (0701), “HDD” (0702), “ROM” (0703), “RAM” (0704), “display” (0705), “GUI” (0706), and the like. Are connected to each other by a data communication path such as a “system bus” (0707), and perform transmission / reception and processing of information. Each unit of the present invention can be expressed as a cursor information generation unit including “CPU” (0701), “HDD” (0702), “ROM” (0703), “RAM” (0704), and the like. . Moreover, it is good also as a structure which records on ROM (0703) or RAM (0704), without using HDD (0702). First, the CPU (0701) activates a cursor information generation program stored at a predetermined address in the ROM (0703), and stores the assigned information in a predetermined area of the RAM (0704). The cursor information is read into the RAM from the table in which the assignment information stored in the HDD (0702) is associated with the cursor information. The read cursor information is used by the GUI (0706), and the cursor is displayed on the display (0705) based on the cursor information.

<Processing flow of Embodiment 1>
FIG. 8 is a diagram illustrating an example of a processing flow according to the first embodiment. First, the cursor information generation unit acquires grant information (S0801), and generates cursor information that also serves as a direction display that can be used in the GUI according to the acquired grant information (S0802). Then, using the generated cursor information, the cursor is displayed on the display on which the GUI is displayed (S0803).

  The above processing can be executed by a program for causing a computer to execute the program, and the program can be recorded on a recording medium readable by the computer (the same applies throughout the present specification).

<Effect of Embodiment 1>
The display device of this embodiment can generate cursor information that also serves as a direction display according to the given information. Thereby, even in a device having a small display screen and difficult to display a plurality of applications at the same time, the direction can be known without displaying the application for performing the direction display.

<< Embodiment 2 >>
<Outline of Embodiment 2>
The display device according to the present embodiment is characterized in that it can acquire instruction information from route navigation, an electronic compass, and the like, and can generate cursor information according to provision information including the instruction information.

<Configuration of Embodiment 2>
FIG. 9 shows an example of functional blocks in the present embodiment. The “display device” (0900) of this embodiment includes a “display” (0901), a “cursor information generation unit” (0902), and an “instruction information output unit” (0903), and further generates cursor information. The section has “applied information acquisition means” (0904). Preferably, the instruction information output unit includes “route guidance processing means” (0905) or “azimuth measurement processing means” (0906).

  The “instruction information output unit” (0903) is configured to output instruction information. “Instruction information” refers to information for indicating a direction. For example, information such as a direction of travel such as a right turn, a left turn, and an oblique right direction, and a direction such as north, south, and southwest corresponds to this. The timing for outputting the instruction information is not particularly limited. The instruction information can be output at all times, every fixed period, or when the user changes due to movement of the user. The instruction information output by the instruction information output unit can be generated / acquired by “route guidance processing means” (0405) or “direction measurement processing means” (0906).

  The “route guidance processing means” (0905) is configured to perform processing for route guidance to the target position. As a device corresponding to the route guidance processing means, there is a navigation device. “Processing for route guidance” refers to, for example, generating or acquiring information for indicating a traveling direction for route guidance, peripheral information, information for performing route guidance by voice, and the like. Information used for route guidance can be generated from current position information and target position information. The current position information is acquired from GPS (Global Positioning System), AGPS (Assisted GPS), VICS (Vehicle Information and Communication System), and the like. Further, the current position information may be acquired from a communication device such as an IC tag installed on a guide board, a sign, a guide block, or the like used in an independent movement support system. The target position information may be a method in which the user directly inputs an address, a zip code, or the like, or may be acquired from a barcode or the like. Using the current position information and the target position information acquired in this way, the route guidance processing means performs route guidance from the current position to the target position. The instruction information output unit (0903) outputs instruction information from the information for route guidance generated or acquired by the route guidance processing means. The instruction information in the route guidance processing means corresponds to, for example, information related to the traveling direction such as right turn, left turn, and diagonally right direction, and information related to the direction such as north and south. At this time, the route guidance using the instruction information does not need to be displayed on the display, and the terminal capable of performing multitasking may be in a state of being activated only in the background. The route guidance may be performed only by voice.

  The “azimuth measurement processing means” (0906) is configured to perform processing for azimuth measurement of the current position. As an apparatus corresponding to the azimuth measurement processing means, for example, an electronic compass apparatus can be cited. The electronic compass refers to a geomagnetic sensor (orientation sensor) using a semiconductor such as an MR (Magneto Resistance) element or an MI (Magneto Impedance) element that detects the north-south geomagnetism where the earth is generated. . “Processing for azimuth measurement” means calculating the azimuth from the geomagnetism detected by the geomagnetic sensor. The instruction information output unit outputs instruction information from the azimuth measurement results acquired by the azimuth measurement processing means. The instruction information in the measurement result of the azimuth measurement processing means corresponds to information for displaying a magnetic needle on a display, for example. At this time, it is not necessary that the direction measurement result as the instruction information is displayed on the display, and in a terminal capable of performing multitasking, it is only activated in the background, or voice guidance is provided. It may be in the state.

  The “assignment information acquisition unit” (0904) is a unit included in the cursor information generation unit (0902), and is configured to acquire the assignment information including the instruction information output from the instruction information output unit as the assignment information. ing. The grant information acquired by the grant information acquisition means may be only the instruction information or may include information other than the instruction information. For example, the instruction information “right licking upward” generated by the route guidance processing unit of the instruction information output unit is acquired as the attached information. In this case, the cursor information generation unit generates cursor information that also serves as a direction display corresponding to the “right lick upward direction”. A method for generating cursor information according to the present embodiment will be described with reference to FIG. (1) shows a case where a normal cursor (1001) is displayed on the GUI. In addition, route navigation is performed separately, and as shown in (2), the traveling direction (1002) in the right lick upward direction is shown. At this time, the display device of the present embodiment acquires the instruction information “right licking upward direction” by the route guidance processing means, generates cursor information that also serves as the direction display, and the right licking upward direction as shown in (3). A cursor (1003) that points to is displayed on the display. In addition, since the instruction information generated or acquired by the route guidance processing unit or the direction measurement processing unit and output from the instruction information output unit is constantly changed by the movement of the user or the like, the given information acquisition unit is always or predetermined Instruction information is acquired every period. Accordingly, the cursor information generation unit can also generate cursor information corresponding to the latest instruction information. In addition, the direction of the cursor as the direction display changes depending on the direction of the display, so it does not indicate the direction on the fixed map, but is instruction information that can display the direction based on the absolute direction. It is desirable to be. By acquiring the grant information including such instruction information, the cursor information generated according to the grant information can be information that can be displayed in an absolute direction regardless of the orientation of the display. it can. If the instruction information is not information for performing an absolute direction display, the cursor information generation unit may generate cursor information capable of performing an absolute direction display (the entire specification). And so on).

  Further, the “cursor information generation unit” (0902) of the present embodiment performs the generation in accordance with provision information including information other than the instruction information output from the instruction information output unit (0903) as the provision information. It may be configured. “Information other than instruction information” refers to information other than information related to a direction. For example, in route guidance, there are information that it is a transit point, information that it is near a destination, information that it is a destination, information that an estimated arrival time is approaching, and the like. The cursor information generation unit generates the cursor information according to the information other than the instruction information and the instruction information by acquiring additional information including information other than the instruction information. At this time, the cursor information generation unit holds a table in which the grant information (information other than the instruction information and the instruction information) is associated with the cursor information, and generates the cursor information from the grant information acquired using the table.

  FIG. 11 is a diagram illustrating an example of a hardware configuration of the display device according to the present embodiment. The operation in the case where the direction information of the route navigation is acquired as the instruction information and the cursor information is generated according to the instruction information will be described using this figure. The display device of this embodiment includes a “CPU” (1101), “HDD” (1102), “ROM” (1103), “I / O” (1104), “RAM” (1105), “GPS antenna” ( 1106), “communication antenna” (1107), “display” (1108), “GUI” (1109), etc., which are connected to each other by a data communication path such as “system bus” (1110). Send / receive and process. Each unit of the present invention includes an instruction information output unit and route guidance processing means: “CPU” (1101), “ROM” (1103), “I / O” (1104), “RAM” (1105), “GPS antenna” ”(1106),“ Communication antenna ”(1107), the cursor information generation unit, and the additional information acquisition unit are configured by“ CPU ”(1101),“ HDD ”(1102),“ ROM ”(1103), and the like. It can be expressed as. Moreover, it is good also as a structure which records on ROM (1103) or RAM (1105), without using HDD (1102).

  Since the instruction information is included in the information for route guidance, it is assumed that information for route guidance is acquired as a premise. The acquisition of information for route guidance will also be briefly described. First, by a user operation, the CPU (1101) activates a navigation program, which is route guidance means stored at a predetermined address in the ROM (1103), and prompts the user to set a destination position. When the target position information is stored in the RAM (1105) via the I / O (1104), the CPU (1101) receives GPS signals from the GPS antenna (1106) at predetermined intervals according to the navigation program. The received GPS signal is temporarily held in the RAM, and the current position is acquired based on the held GPS signal. In the acquisition of the current position, in the case of external acquisition, the held GPS signal is once transmitted to the outside via the communication antenna (1107), the transmission destination performs calculation, receives the result, and stores it in the RAM. Next, a route from the current position to the target position is calculated using a route calculation program in the navigation program based on the target position information stored in the RAM and the current position information stored in the RAM. To store. Note that the calculation may be performed outside including the calculation of the route, and only the information indicating the calculated route may be acquired from the outside. In that case, route information received from the outside is stored in the RAM. Information for performing navigation to the destination is acquired based on the route information. Then, from the map information including the current location stored in the RAM and the route information, the next action to be taken by the user, for example, information such as turning right, turning left, or going straight, is obtained by calculation of the CPU, and this is actually obtained. Is converted into information to be shown to the user by a program for generating route guidance in the navigation program, and stored in the RAM as route guidance information. The CPU activates a cursor information generation program stored at a predetermined address in the ROM, outputs instruction information from the route guidance information stored in the RAM, and newly stores it in the RAM as instruction information. As a result, the CPU reads the cursor information into the RAM from the table in which the instruction information stored in the HDD (1102) is associated with the cursor information. The read cursor information is used by the GUI (1109) and displayed on the display (1108).

<Processing flow of Embodiment 2>
FIG. 12 is a diagram illustrating an example of a processing flow according to the first embodiment. First, the instruction information output unit outputs instruction information for indicating a direction (instruction information output step S1201). The cursor information generation unit acquires the assignment information including the instruction information output in S1201 (assignment information acquisition step S1202). Then, according to the provision information acquired in S1202, cursor information that also serves as a direction display that can be used in the GUI is generated (cursor information generation step S1203). Finally, a cursor is displayed on the display on which the GUI is displayed using the generated cursor information (S1204).

<Effect of Embodiment 2>
According to the display device of this embodiment, it is possible to generate cursor information that also serves as a direction display in accordance with application instruction information such as route navigation and an electronic compass. Thereby, even in a device having a small display screen and difficult to display a plurality of applications at the same time, the direction can be known without displaying the application for performing the direction display.

<< Embodiment 3 >>
<Outline of Embodiment 3>
The display device according to the present embodiment includes a cursor rotation information generation unit in order to prevent the visibility of the indication point of the cursor from being lowered than the original cursor due to the cursor also serving as a direction display. The display point can be displayed without being changed.
<Configuration of Embodiment 3>
FIG. 13 shows an example of functional blocks in the present embodiment. The “display device” (1300) of the present embodiment is based on the first embodiment and includes a “display” (1301) and a “cursor information generation unit” (1302). It has a cursor rotation information generating means ”(1303). The present embodiment is based on the first embodiment, but may be based on the second embodiment.

  The “cursor rotation information generation unit” (1303) is a unit included in the cursor information generation unit (1302), and the cursor rotation is performed as cursor information that also serves as a direction display that can be used in the GUI (1310) according to the given information. It is configured to generate information. Since the cursor information is generated according to the grant information, when the grant information is changed, the direction indicated by the cursor may be similarly changed. FIG. 14 shows an example where the rotation axis of the cursor is the center of the cursor graphic. In this case, when the pointing direction is changed, the cursor is displayed as (1) even at the same position. For example, as shown in FIG. 14 (2), in the case of the cursor pointing to the upper left as the direction display and the case of displaying the upper right as the direction display, the indicated characters are “A” and “I”. It will change like this. The same problem occurs even when the rotation axis of the cursor is the center of gravity of the cursor graphic. Therefore, the cursor rotation information generation means generates the cursor rotation information so as not to impair the accuracy and visibility of the cursor indication point as described above. “Cursor rotation information” refers to information for rotating and displaying a cursor around a coordinate point on the GUI that the cursor should point to. As shown in FIG. 15 (1), even when the given information is changed by rotating around the coordinate point on the GUI that the cursor should originally point to and the direction of the cursor as the direction display is changed, The original function of the cursor is not impaired. In the case of FIG. 15 (2), even if the direction display changes from pointing to the upper left to pointing to the upper right, the indicated character does not change to “yes”.

  Since the hardware configuration of the display device of the present embodiment is the same as that of the first embodiment, the operation of the display device that generates cursor rotation information according to the given information will be described with reference to FIG. The cursor rotation information generation means can be expressed as being composed of “CPU” (0701), “HDD” (0702), “ROM” (0703), “RAM” (0704), and the like. Further, as in the first embodiment, the HDD (0702) may not be used, and the ROM (0703) or RAM (0704) may be recorded. First, the CPU (0701) activates a cursor rotation information generation program stored at a predetermined address in the ROM (0703), and stores the assigned information in a predetermined area of the RAM (0704). At this time, coordinate information on the GUI pointed to by the cursor is always acquired as the grant information. The cursor information is read into the RAM from the table in which the assignment information stored in the HDD (0702) is associated with the cursor information. This correspondence table may be the same as the table described in the first embodiment. Alternatively, the cursor information may be calculated by calculation based on the provision information instead of the table. Further, the CPU moves the coordinates of the tip of the cursor indicated by the generated cursor information to the coordinates on the GUI pointed to by the cursor included in the assignment information, and reads them into the RAM as cursor rotation information. Finally, the read cursor rotation information is used by the GUI (0706), and the cursor is displayed on the display (0705) based on the cursor rotation information.

As cursor information that also serves as a direction display that can be used in the GUI (1610) according to the provision information, the cursor form is displayed. It is configured to generate information. The “cursor form information” is information for changing the form of the cursor and displaying it on the GUI (1610). The form of the cursor means, for example, the shape, color, pattern, size, blinking, and blinking of the cursor. By changing the form of the cursor, it is possible to distinguish between a normal cursor and a cursor that also serves as a direction display. FIG. 17 shows an example of a change in the shape of the cursor. For example, a cursor (1702) having a different color from the normal cursor (1701) as shown in (1) or a large cursor (1703) as shown in (2) can be used. In addition, when the instruction information acquired from the route guidance processing means is the instruction information to turn right, the direction indication can be accurately recognized in the form of the cursor (1704) bent to the right as shown in (3). Can do. Further, when the instruction information is acquired from the azimuth measurement processing means, it may be in the form of a cursor (1705) indicating the azimuth as shown in (4). In this case, the downward direction is north. Also, if the cursor is larger than usual, characters and icons will be hidden under the cursor. For example, by setting the cursor to a frame-only form or a translucent form, There is no loss of functionality. The form of the cursor also serving as the direction display is, for example, when the provision information including the instruction information acquired from the route guidance processing means is acquired, the cursor information is set to blue, and the provision information including the instruction information from the direction measurement processing means is changed. If acquired, the cursor may be set as a default such as a cursor form as shown in FIG. In addition, the user may select what cursor form to use. In addition, as described in the second embodiment, when the grant information is information including information other than the instruction information, only different cases can be used. For example, when it is near the destination, the cursor can be blinked or the color can be changed.

  Since the hardware configuration of the display device of the present embodiment is the same as that of the first embodiment, the operation of the display device that generates the cursor form information according to the given information will be described with reference to FIG. The cursor form information generation means can be expressed as “CPU” (0701), “HDD” (0702), “ROM” (0703), “RAM” (0704), and the like. Further, as in the first embodiment, the HDD (0702) may not be used, and the ROM (0703) or RAM (0704) may be recorded. First, the CPU (0701) activates the cursor form information generation program stored at a predetermined address in the ROM (0703), and stores the assigned information in a predetermined area of the RAM (0704). Then, the cursor form information is read into the RAM from the table in which the assignment information stored in the HDD (0702) is associated with the cursor form information. The table may be a default table when the grant information is acquired, or a table selected by the user may be used. The read cursor form information is used by the GUI (0706), and the cursor is displayed on the display (0705) based on the cursor form information.

<Processing Flow of Embodiment 4>
The processing flow of the fourth embodiment is the same as that shown in FIG. 8, and is different only in that cursor form information is generated as cursor information. First, the cursor information generation unit acquires grant information (S0801). Then, in accordance with the acquired grant information, it also serves as a direction display usable in the GUI, and generates cursor form information that is information for displaying on the GUI by changing the form of the cursor (S0802). Finally, a cursor is displayed on the display on which the GUI is displayed using the generated cursor form information (S0803).

<Effect of Embodiment 4>
According to the display device of the present embodiment, the form of the cursor that also serves as the direction display can be different from the form of the normal cursor. This makes it easy to recognize that the cursor also serves as a direction display. It is also possible to change to a cursor form that does not affect the accuracy and visibility of the pointing points of cursors of other applications.

<< Embodiment 5 >>
<Outline of Embodiment 5>
When the change in direction display and the movement of the cursor occur simultaneously, the change in the cursor cannot be predicted, and the visibility of the indication point of the cursor is deteriorated. The curl display device according to the present embodiment is characterized in that it is determined whether or not the cursor is moving in the GUI, and cursor information is generated according to the result.

<Configuration of Embodiment 5>
FIG. 18 shows an example of functional blocks in the present embodiment. The “display device” (1800) of the present embodiment is based on the first embodiment and includes a “display” (1801) and a “cursor information generation unit” (1802). Means "(1803) and" state dependency generation means "(1804). The present embodiment is based on the first embodiment, but may be based on other embodiments.

  The “determination unit” (1803) is a unit included in the cursor information generation unit (1804), and is configured to determine whether the cursor is moving in the GUI (1810) or not. Movement within the GUI can be determined by acquiring the coordinates in the GUI pointed to by the cursor by the mouse driver and changing the coordinates.

  The “state dependency generation unit” (1804) is a unit included in the cursor information generation unit (1802), and is configured to vary the generation according to the given information according to the determination result of the determination unit (1803). Yes. That is, different cursor information is generated depending on the determination result that the cursor is moving in the GUI and the determination result that the cursor is stationary in the GUI. FIG. 19 shows a case where the cursor position is moved horizontally from a to e in the GUI while the cursor form as the direction display changes from the left direction to the upper right direction via the upward direction. When the direction of the cursor as the direction display is changed and the cursor moves in the GUI, the position and orientation of the cursor on the display are changed simultaneously as shown in (1). It is difficult to specify the position to point to. Therefore, for example, when the cursor is moving in the GUI, as shown in (2), it is possible to prevent new cursor information from being generated according to the provision information acquired during the movement. In this case, since it is unknown whether the cursor is changed to a direction display, as shown in (3), the cursor information is not generated according to the added information acquired during the movement, but the pattern is changed. You may make it change the cursor form, such as. As another example, when the cursor is moving in the GUI, as shown in (4), the generation according to the provision information may not be performed. Thereby, during the movement of the cursor, the cursor as the direction display is not changed, and the visibility of the indication point of the cursor is not impaired.

  Since the hardware configuration of the display device according to the present embodiment is the same as that of the first embodiment, the operation of the display device that generates cursor information according to the state of the cursor will be described with reference to FIG. The determination means are “CPU” (0701), “ROM” (0703), “RAM” (0704), and the state dependency generation means are “CPU” (0701), “HDD” (0702), “ROM” ( 0703), “RAM” (0704). Further, as in the first embodiment, the HDD (0702) may not be used, and the ROM (0703) or RAM (0704) may be recorded. First, the CPU (0701) activates a cursor information generation program stored at a predetermined address in the ROM (0703), and stores the assigned information in a predetermined area of the RAM (0704). Further, the CPU always acquires coordinate information on the GUI pointed to by the cursor from the mouse driver and stores it in the RAM. Then, when the coordinate information is compared with the next acquired coordinate information, the flag “1” is determined as a determination result that the cursor is moving, and when the coordinate information is not changed, the cursor is changed. As a result of determination that is not moving, a flag of “0” is set in the grant information. Next, the CPU reads the cursor information into the RAM using a table in which the assignment information stored in the HDD (0702) corresponding to the flag “1” or “0” is associated with the cursor information. As a table associated with “1”, for example, a table associated with cursor information for displaying a cursor of a color different from that before the movement, or a cursor information not including instruction information is associated with the table. Table. The table may be a default table when the grant information is acquired, or a table selected by the user may be used. The read cursor information is used by the GUI (0706), and the cursor is displayed on the display (0705) based on the cursor information.

<Processing Flow of Embodiment 5>
FIG. 20 is a diagram illustrating an example of a processing flow according to the fifth embodiment. First, the cursor information generation unit acquires grant information (S2001). Then, it is determined whether the cursor is moving within the GUI (determination step S2002). If the result of the determination is that the cursor is moving (YES in S2002), the cursor information that also serves as a directional display that can be used in the GUI is generated according to the acquired grant information and the determination result that the cursor is moving. (State-dependent generation step S2003). On the other hand, if the determination result indicates that the cursor is not moving (NO in S2002), the cursor information that also serves as a direction display that can be used in the GUI is determined according to the acquired grant information and the determination result that the cursor is not moving. Generate (state-dependent generation step S2004). Finally, the cursor is displayed on the display on which the GUI is displayed using the generated cursor information (S2005).

<Effect of Embodiment 5>
According to the display device of the present embodiment, it is possible to determine whether the cursor is moving in the GUI, and to generate different cursor information. Thereby, when the change in the direction display and the movement of the cursor occur at the same time, it is possible to prevent the accuracy and visibility of the indication point of the cursor from being deteriorated.

Embodiment 6
<Overview of Embodiment 6>
Since the cursor also serves as a direction display, there is a possibility that the cursor is not displayed when it is desired to indicate the end of the display. Therefore, the display device of the present embodiment is characterized in that control is performed so that the entire cursor graphic is always displayed on the display.

<Configuration of Embodiment 6>
FIG. 21 shows an example of functional blocks in the present embodiment. The “display device” (2100) of the present embodiment is based on the first embodiment and includes a “display” (2101) and a “cursor information generation unit” (2102). The display control means ”(2103) is included. The present embodiment is based on the first embodiment, but may be based on other embodiments.

  The “all display control unit” (2103) is a unit included in the cursor information generation unit (2102), and is configured to control so that the entire cursor graphic is always displayed on the display (2101). As shown in FIG. 22, when it is desired to point to the icon at the left end of the display ("return" icon in the figure) as the original function of the cursor, when the cursor as the direction display indicates the upper right direction The cursor (2201) is no longer displayed on the display. Therefore, the all display control means controls so that the entire cursor graphic is always displayed on the display. For example, as shown in FIG. 22 (2), by scrolling the entire screen (2203) displayed on the display in the right direction, the entire figure of the cursor (2202) can be controlled to be displayed. it can. In addition, as shown in FIG. 22 (3), the screen (2205) in a range excluding the portion that is more convenient when it is always visible on the user interface instead of the entire screen is scrolled to the right. Thus, the entire graphic of the cursor (2204) may be controlled to be always displayed on the display. Furthermore, it may be controlled so that the form of the cursor is changed to be displayed on the display and the change can be recognized. For example, by setting the cursor to be a cursor that is displayed in the display and blinking the cursor, the user can recognize that the cursor does not serve as a direction display.

  An example of a screen scrolling method will be described with reference to FIG. The scroll processing method shown in the figure is an example, and the present invention is not limited to this. The hardware configuration of the display device according to the present embodiment is the same as that of the first embodiment, and will be described with reference to FIG. The all display control means can be expressed as “CPU” (0701), “HDD” (0702), “ROM” (0703), “RAM” (0704), and the like. First, the position of the cursor in the GUI (0706) is determined by dividing the display into five areas as shown in FIG. Each area is designated by display coordinates. The upper area of the display is an A area, the right part is a B area, the lower part is a C area, the left part is a D area, and the other (center) is an E area. The CPU (0701) activates the entire display control program stored in a predetermined area of the ROM (0703), acquires information on which area the root coordinates and the tip coordinates of the cursor are in by the mouse driver, (0704). Furthermore, the movement direction information of the cursor is acquired and read into the RAM. As the cursor movement direction information, the cursor tip coordinates are acquired every predetermined time, and the direction advanced from the coordinate information is acquired as a vector. Thereby, the moving direction of the cursor can be known. Then, the CPU reads the scroll direction into the RAM by using a table for calculating the scroll direction of the screen from the cursor position and the moving direction stored in the HDD (0702) as shown in FIG. . For example, when the cursor is in the area A and the cursor moves upward, the screen is scrolled downward. At this time, the width for scrolling the screen is calculated so that both the root coordinates and the tip coordinates of the cursor fall within the GUI. By performing such processing, the cursor can always be displayed in the display (0705).

<Processing flow of Embodiment 6>
FIG. 24 is a diagram illustrating an example of a processing flow according to the sixth embodiment. First, cursor coordinate information and cursor movement direction information are acquired (S2401, S2402). Then, based on the acquired coordinate information and movement direction information, it is determined whether or not there is a possibility that a part of the cursor moves to a position that protrudes from the screen (S2403). If the result of the determination is that there is a possibility that the image will protrude from the screen (YES in S2403), the entire screen is scrolled with respect to the display (S2404). Then, a cursor based on the cursor information is displayed on the GUI after the scroll process (S2405).

<Effect of Embodiment 6>
According to the display device of the present embodiment, the entire figure of the cursor can always be displayed on the display. Thereby, it can prevent that the visibility of the indication point of a cursor deteriorates because a cursor serves as direction indication.
