Description

  The present invention relates to a cursor movement control device and a program.

  2. Description of the Related Art Conventionally, a thin client system is known in which a client terminal used by a user performs necessary minimum processing and most processing is concentrated on a server device side. The server device transmits screen data to be displayed on the client terminal to the client terminal for display. The client terminal receives and displays the screen data from the server device, allows the local cursor (pointer) to move on the display screen, accepts an operation by the user, and transmits event information corresponding to the operation to the server device. Yes. The local cursor is a cursor on the client terminal side.

  In the client terminal, if it is determined that the moving speed or moving distance of the pointer performed by operating the pointing device is faster than the preset speed or longer than the preset distance, it is determined that the pointer is simply moving. A thin client system that omits transmission of event information to a server device is known (see, for example, Patent Document 1). It is possible to reduce the power consumption of the client terminal by reducing the number of useless event information transmissions to the server device.

  In addition, a portable terminal that automatically displays an e-mail with a scroll speed and the number of scroll lines set in advance when the amount of e-mail data exceeds a predetermined value is known (for example, Patent Document 2). reference).

  There is a demand to use a portable terminal as a client terminal of a thin client system. A portable terminal generally has a display unit that displays a rectangular screen. Some portable terminals can switch between a vertically long screen having a long side of a rectangle in a vertical direction and a horizontally long screen having a long side of a rectangle in a horizontal direction.

  However, if a mobile device with a slow drawing speed on a landscape screen compared to a portrait screen is used as a client terminal for a thin client system, the movement speed of the local cursor on a landscape screen will be slower than on a portrait screen. When moved quickly, the cursor display cannot follow. This is because the load required for the drawing process of the display screen of the portable terminal is larger in the case of the landscape screen than in the case of the portrait screen.

  Conventional thin client systems that omit the transmission of event information according to the moving speed and moving distance of pointers, and portable terminal devices that display e-mails at a predetermined scrolling speed and the number of scroll lines are local on a vertically long screen and a horizontally long screen. It does not control the amount of cursor movement. For this reason, in the thin client system using a portable terminal, it cannot be solved that the moving speed of the local cursor differs between the portrait screen and the landscape screen.

  Although a method in which the user sets the movement speed of the local cursor in advance can be considered, the operation burden on the user is large. In addition, the moving speed of the local cursor may change depending on the load on the client terminal even if the operation is set in advance.

  Next, the operation of the thin client system 1 will be described with reference to FIGS. FIG. 3 shows a cursor movement control process executed on the client terminal 20. FIG. 4 shows the coordinates of the portrait screen 241. FIG. 5 shows a first cursor display process of the cursor movement control process. FIG. 6 shows the coordinates of the landscape screen 242. FIG. 7 shows a second cursor display process of the cursor movement control process.

  First, the basic operation of the thin client system 1 will be described. For example, in the client terminal 20, when the CPU 21 inputs a connection instruction to the server device 10 via the operation unit 22 from the user, the wireless communication unit 26 causes the server device to communicate via the base station 30 and the communication network N. A connection request to 10 is transmitted to the server device 10.

  Then, the server device 10 receives the connection request from the client terminal 20, activates the application program corresponding to the received connection request, creates frame data of the display screen of the application program, and sets the communication network N and the base station 30. Then, the created frame data is transmitted to the client terminal 20.

  In the client terminal 20, when the CPU 21 receives the frame data from the server device 10 through the wireless communication unit 26, the CPU 21 displays a screen on the display unit 24 based on the received frame data, and displays the display screen via the operation unit 22. The operation input according to is accepted. At this time, a local cursor is displayed on the display screen, and an operation input for moving the local cursor is accepted.

  When the operation input is made via the operation unit 22, the CPU 21 creates event information corresponding to the operation input, and the event information is generated by the wireless communication unit 26 via the base station 30 and the communication network N. It transmits to the server apparatus 10.

  Then, the server device 10 receives event information from the client terminal 20, and executes processing related to the application program in response to the received event information. Further, the server device 10 creates frame data of a new display screen of the application program after executing the process according to the event information or periodically, and sends the created frame data via the communication network N and the base station 30. It transmits to the client terminal 20.

  In this manner, screen display, operation input and event information transmission by the client terminal 20 and processing execution and frame data transmission according to the event information by the server device 10 are repeatedly executed until the operation by the client terminal 20 is completed. .

  For example, the case where the application program to be executed is a document editing program for editing document data stored in the server device 10 will be briefly described. The server device 10 activates a document editing program according to the execution instruction information from the magnetic client terminal 20 and transmits the frame data of the document editing screen to the client terminal 20.

  The CPU 21 of the client terminal 20 receives frame data from the server device 10 through the wireless communication unit 26 and displays a document editing screen corresponding to the frame data on the display unit 24. Then, the CPU 21 receives an operation input corresponding to the document editing screen via the operation unit 22, and transmits it as event information to the server device 10 by the wireless communication unit 26.

  The server device 10 receives event information from the client terminal 20 and executes processing according to the event information. For example, when the event information is update data of document data, the server apparatus 10 updates the document data stored in the own device according to the event information.

  Next, a cursor movement control process executed on the client terminal 20 will be described. The cursor movement control process is a process for controlling movement and display so that the movement speed of the local cursor on the landscape screen matches the movement speed of the portrait screen in the screen display corresponding to the frame data received from the server device 10. .

  In the client terminal 20, for example, in response to transmission of a connection request to the server device 10, the frame data of the display screen from the server device 10 is received by the wireless communication unit 26, and the screen to the display unit 24 corresponding to this frame data And display of the local cursor in the screen is started. Using the display of the screen and the local cursor on the display unit 24 as a trigger, the CPU 21 executes the cursor movement control process according to the cursor movement control program read from the ROM 25 and appropriately expanded in the RAM 23 by the CPU 21.

  As shown in FIG. 3, first, the CPU 21 determines whether or not the display screen of the display panel 24a of the display unit 24 is a vertically long screen according to the detection result of the display screen by the vertical and horizontal detection unit 28 (step S11). ). If the screen is a portrait screen (step S11; YES), the CPU 21 holds (stores) the local cursor movement start coordinates (x0, y0) in the display screen in the RAM 23, sets the variable n to 0, and counts the time 29 The timer t is started according to the time information output from (Step S12).

  As shown in FIG. 4, when the screen being displayed on the display unit 24 is a vertically long screen 241 of FWVGA, the coordinates (x, x) are set in units of pixels with the upper left end point as the origin O and the short side L1 and the long side L2 as axes. y) is taken and the movement start coordinates (x0, y0) are taken. Further, the timer t is counted up with time according to the time information output from the time measuring unit 29.

  And CPU21 discriminate | determines whether there exists any movement operation of a local cursor by the operation input to the operation part 22 from a user (step S13). When there is no local cursor movement operation (step S13; NO), the process proceeds to step S11. When there is an operation of moving the local cursor (step S13; YES), the CPU 21 determines whether or not the timer t being counted has passed a preset threshold time th (step S14). For example, the time th is 40 [ms], but is not limited thereto.

  When the timer t has not passed the time th (step S14; NO), the process proceeds to step S14. When the timer t has passed the time th (step S14; YES), the CPU 21 executes a first cursor display process for displaying a local cursor (step S15).

  Here, the first cursor display processing in step S15 will be described with reference to FIG. First, the CPU 21 uses the wireless communication unit 26 to indicate the current local coordinates (x1, y1) of the local cursor corresponding to the local cursor movement input of the operation unit 22 on the vertically long screen being displayed on the display unit 24 as event information. The cursor position information x1, y1 is transmitted to the server device 10 (step S151). The current coordinates (x1, y1) are, for example, coordinates (x1, y1) shown in FIG. The server device 10 receives the current location information x1 and y1 as event information from the client terminal 20 via the base station 30 and the communication network N, and performs various processes according to the received location information x1 and y1.

  Then, the CPU 21 moves the local cursor to the coordinates (x1, y1) acquired in step S151 and displays it on the vertically long screen of the display unit 24 (step S152), and ends the first cursor display process.

Returning to FIG. 3, after executing step S15, the CPU 21 holds the current coordinates (x1, y1) used for local cursor display in step S15 in the RAM 23 (step S16). Then, the CPU 21 calculates the movement distance l1 of the local cursor using the following equation (1) and stores it in the RAM 23 (step S17).
l1 = {(x1-x0) ² + (y1-y0) ² } ^1/2 (1)
The movement distance l1 is a distance between the current coordinates (x1, y1) and the coordinates (x0, y0) shown in FIG.

Then, the CPU 21 calculates the local cursor moving speed v1 using the following equation (2) and stores it in the RAM 23 (step S18).
v1 = l1 / t (2)

  Then, the CPU 21 increments the variable n by 1, sets the timer t to 0, and sets the value of the current coordinate (x1, y1) to the coordinate (x0, y0) (step S19). Then, the CPU 21 determines whether or not the variable n is a preset integer threshold value nh (step S20). When the variable n is less than the threshold value nh (step S20; NO), the process proceeds to step S13.

When the variable n is greater than or equal to the threshold value nh (step S20; YES), the CPU 21 calculates (moving) average speed v1_ave of the local cursor using the following equation (3) and stores it in the RAM 23 (step S22).
v1_ave = Σv1 / n (3)
Σv1 is an addition value of the new n moving speeds v1 up to the present time.

  And CPU21 sets the variable n to 0 (step S22). Then, the CPU 21 ends the application program, and determines whether or not to end the screen as the client of the display unit 24 and the local cursor display (step S23). When the display as a client is not terminated (step S23; NO), the process proceeds to step S13. When the display as a client is terminated (step S23; YES), the cursor movement control process is terminated. At this time, the CPU 21 transmits application program end instruction information to the server device 10 by the wireless communication unit 26.

  When the screen is a landscape screen (step S11; NO), the CPU 21 holds the movement start coordinates (x0, y0) of the local cursor in the RAM 23, sets the variable n to 0, and sets the time information output from the time measuring unit 29. In response, the timer t is started (step S24).

  As shown in FIG. 6, when the screen being displayed on the display unit 24 is a vertically long screen 241 of FWVGA, the coordinates (x, x) of the pixel unit with the upper left end point as the origin O and the long side L2 and the short side L1 as axes. y) is taken and the movement start coordinates (x0, y0) are taken.

  And CPU21 discriminate | determines whether there exists any movement operation of a local cursor by the operation input to the operation part 22 from a user (step S25). When there is no local cursor movement operation (step S25; NO), the process proceeds to step S11. When there is a local cursor movement operation (step S25; YES), the CPU 21 determines whether or not the timer t being counted has passed a preset threshold time th (step S26).

  When the timer t has not passed the time th (step S26; NO), the process proceeds to step S26. When the timer t has passed the time th (step S26; YES), the CPU 21 executes a second cursor display process for displaying a local cursor (step S27).

  Here, the first cursor display processing in step S15 will be described with reference to FIG. First, the CPU 21 determines whether or not an average speed v1_ave and an average speed v2_ave described later are being held in the RAM 23 (step S271). When the average speeds v1_ave and v2_ave are being held (step S271; YES), the CPU 21 determines whether or not the average speeds v1_ave and v2_ave being held are v1_ave> v2_ave (step S272).

When v1_ave> v2_ave (step S272; YES), the CPU 21 calculates the current coordinates (x2, y2) of the local cursor according to the local cursor movement input of the operation unit 22 according to the following expressions (4) and (5), The corrected position information x2b, y2b is calculated using the movement direction being held, which will be described later, and held in the RAM 23 (step S273).
x2b = x2 ± (v1_ave−v2_ave) * th (4)
y2b = y2 ± (v1_ave−v2_ave) * th (5)
The corrected position information x2b, y2b corresponds to, for example, the coordinates (x2b, y2b) shown in FIG. Further, ± in Expression (4) corresponds to ± in the movement direction in the X direction being held. In the equation (5), ± corresponds to ± in the moving direction in the Y direction during holding.

  Then, the CPU 21 sets the current coordinates (x2b, y2b) of the local cursor on the vertically long screen being displayed on the display unit 24 calculated in step S273 as current position information x2b, y2b as event information by the wireless communication unit 26. It transmits to the apparatus 10 (step S274). The server device 10 receives the current location information x2b, y2b, which is event information, from the client terminal 20 via the base station 30 and the communication network N, and performs various processes according to the received location information x2b, y2b.

  Then, the CPU 21 moves the local cursor to the coordinates of the current coordinates (x2b, y2b) calculated in step S273 and displays it on the horizontally long screen of the display unit 24 (step S275), and ends the second cursor display process. .

  When the average speeds v1_ave and v2_ave are not being held (step S271; NO), or when v1_ave> v2_ave is not satisfied (step S272; NO), the CPU 21 moves the local cursor of the operation unit 22 on the horizontally long screen displayed on the display unit 24. The current coordinates (x2, y2) of the local cursor according to the input are transmitted to the server device 10 as the current local cursor position information x2, y2 by the wireless communication unit 26 (step S276). The server device 10 receives the current location information x2 and y2 as event information from the client terminal 20 via the base station 30 and the communication network N, and performs various processes according to the received location information x2 and y2.

  Then, the CPU 21 moves the local cursor to the coordinates (x2, y2) acquired in step S276 and displays it on the horizontally long screen of the display unit 24 (step S277), and ends the second cursor display process.

  Returning to FIG. 3, after executing step S27, the CPU 21 holds the current coordinates (x2, y2) used for local cursor display in step S27 in the RAM 23 (step S28). When the current coordinates (x2b, y2b) are used for local cursor display in step S27, the current coordinates (x2b, y2b) are held in the RAM 23 as current coordinates (x2, y2) in step S28.

Then, the CPU 21 calculates the movement distance l2 of the local cursor using the following equation (6) and holds it in the RAM 23 (step S29).
l2 = {(x2−x0) ² + (y2−y0) ² } ^1/2 (6)
The movement distance l2 is a distance between the coordinate (x2, y2) (coordinate (x2b, y2b)) and the coordinate (x0, y0) after the movement shown in FIG.

  Then, the CPU 21 calculates the moving direction of the local cursor and stores it in the RAM 23 (step S30). The moving direction of the local cursor is calculated as positive / negative (±) of the value of the change in the x direction (x2−x0) and positive / negative (±) of the change in the y direction (y2−y0). For example, in the example shown in FIG. 6, since x2> x0 and y2> y0, the moving direction of the local cursor is x direction: + and y direction: +.

Then, the CPU 21 calculates the moving speed v2 of the local cursor using the following equation (7) and stores it in the RAM 23 (step S31).
v2 = l2 / t (7)

  Then, the CPU 21 increments the variable n by 1, sets the timer t to 0, and sets the value of the current coordinate (x2, y2) to the coordinate (x0, y0) (step S32). Then, the CPU 21 determines whether or not the variable n is a preset threshold value nh (step S33). When the variable n is less than the threshold value nh (step S33; NO), the process proceeds to step S25.

When the variable n is greater than or equal to the threshold value nh (step S20; YES), the CPU 21 calculates the average (v) moving speed v2_ave of the local cursor using the following equation (8) and stores it in the RAM 23 (step S34).
v2_ave = Σv2 / n (8)
Σv2 is an added value of the new n moving speeds v2 up to the present time.

  And CPU21 sets the variable n to 0 (step S35). And CPU21 complete | finishes an application program and discriminate | determines whether the screen and local cursor display as a client of the display part 24 are complete | finished (step S36). If the display as a client is not terminated (step S36; NO), the process proceeds to step S25. When the display as the client is ended (step S36; YES), the cursor movement control process is ended. At this time, the CPU 21 transmits application program end instruction information via the wireless communication unit 26 to the server device 10.

  As described above, according to the present embodiment, the client terminal 20 includes the rectangular display panel 24a, the display unit 24 that displays a screen as a horizontally long screen or a vertically long screen on the display panel 24a, and the display screen of the display unit 24. A vertical / horizontal detection unit 28 for detecting whether the screen is a landscape screen or a portrait screen. Further, the client terminal 20 calculates an average speed v1_ave of the local cursor when the display screen is a landscape screen and an average speed v2_ave of the local cursor when the display screen is a portrait screen, and the cursor terminal when the display screen is a portrait screen. When the average speed v1_ave is faster than the average cursor speed v2_ave on the landscape screen, the CPU 21 increases the cursor movement amount on the landscape screen to the same value as the cursor movement amount on the landscape screen. Is provided.

  For this reason, in the thin client system 1, the local cursor can be moved at the same speed as the portrait screen on the landscape screen without any setting by the user.

  Further, the CPU 21 of the client terminal 20 transmits the position information of the local cursor as event information to the server device 10 by the wireless communication unit 26, and generates the position information of the local cursor based on the increased amount of movement of the local cursor. Then, the local cursor is displayed on the display screen based on the position information, and the generated position information is transmitted to the server device 10. For this reason, in the thin client system 1, the server apparatus 10 performs processing related to the application program provided to the client terminal 20 according to the position information of the local cursor at the same speed as that of the portrait screen on the landscape screen received from the client terminal 20. Can be performed appropriately.

In the above description, an example in which the ROM 25 is used as a computer-readable medium for the program according to the present invention is disclosed, but the present invention is not limited to this example.
As other computer-readable media, a non-volatile memory such as a flash memory and a portable recording medium such as a CD-ROM can be applied.
A carrier wave is also applied to the present invention as a medium for providing program data according to the present invention via a communication line.

  The description in the above embodiment is an example of the cursor movement control device and the program according to the present invention, and the present invention is not limited to this.

  In the above embodiment, the client terminal 20 is a mobile terminal. However, the present invention is not limited to this. The client terminal 20 may be a stationary terminal as long as the terminal can be switched between a vertically long screen and a horizontally long screen, and the moving speed of the local cursor is slower than that of the vertically long screen.

  In the said embodiment, although the operation part 22 of the client terminal 20 was set as the key operation part, it is not limited to this. In the client terminal, the operation unit may include a pointing device such as a mouse, and may be configured to control the movement of the local cursor (pointer) of the pointing device.

  In the above embodiment, the average speeds v1_ave and v2_ave of the local cursor are repeatedly calculated during the screen display. However, the present invention is not limited to this. For example, the average speed of the local cursor may be calculated from the movement of the local cursor in the cursor speed detection mode provided in advance, and is calculated in the initial state when the display screen is switched to the portrait screen or landscape screen. It is good also as a structure.

  In addition, the determination conditional expression in step S272 of the second cursor display process of the cursor movement control process of FIG. 7 of the above embodiment is v1_ave> k * v2_ave (k = arbitrary coefficient, for example, 1.1), and the coefficient It is good also as a structure which can set k.

  Further, in the above embodiment, in the calculation of the position information x2b and y2b in step S273 of the cursor movement control process of FIG. 7, the movement amount of the local cursor on the landscape screen is set to the movement amount of the cursor on the portrait screen. The value is increased to the same value, but is not limited to this. In the calculation of the position information x2b and y2b, the amount of movement of the local cursor on the landscape screen may be increased to a value that is substantially the same as the amount of movement of the local cursor on the portrait screen.

  Of course, the detailed configuration and detailed operation of each component of the thin client system 1 in the above embodiment can be changed as appropriate without departing from the spirit of the present invention.
