JP 2000-194472 A Japanese Patent Laid-Open No. 11-85835

  It is an object of the present invention to make it possible for the user to set the focus movement for parts such as a plurality of buttons on the display screen in a user-friendly manner.

  The focus movement method of a component on the display screen according to the present invention is such that when a focus is moved from an arbitrary component arranged on the display screen to another component by a key operation, a predetermined value is assigned to the focus number assigned to the arbitrary component. Performing a calculation for adding or subtracting the value, searching for a part assigned a focus number that matches the value of the calculation, moving the focus to the part that matches the search, and confirming after the focus And a step of operating the key to determine the focus of the component.

  In the present invention, when a key operation is performed to move the focus from an arbitrary part to another part, a calculation for adding or subtracting a predetermined value to the focus number of the arbitrary part is executed, and the calculated value coincides with the calculated value. If you search for a part that has a focus number and focus on the part that matches the search, you can confirm the focus by pressing the Enter key. An operating environment similar to that when a touch operation is performed can be obtained.

  The method preferably includes a step of arbitrarily assigning focus numbers to a plurality of parts using a setting screen.

  For example, the focus numbers “1” and “2” are consecutive for the components arranged on the left and right on the display screen, the focus numbers are set for the upper components, for example, “1”, and for the lower components, for example, “1”. By setting “11”, the focus number can be moved to the component arranged in the left-right direction by setting the above value to the plus or minus 1 in the left-right direction, and the focus number in the up-down direction. By setting the value to plus 10 or minus 10, it is possible to move the focus to the parts arranged in the vertical direction.

  The display device according to the present invention is operated to display a display screen, an operation key operated to move the focus from an arbitrary component arranged on the display screen to another component, and the focus. A function for assigning a focus number to a part on the display screen, and a focus number assigned to the arbitrary part when the focus is moved from the arbitrary part to another part by operating the operation key. A function for executing a calculation for adding or subtracting a predetermined value to a value, a function for searching for a part having a focus number that matches the value of the calculation, a function for moving the focus to a part that matches the search, and a function after this focus And a function for operating the confirmation key to confirm the focus of the component.

  In the case of the display device, the operation keys are preferably provided with arrow marks corresponding to the arrangement of parts on the display screen at the key tops. With this operation key, the arrow mark allows the user to easily select a component to be focused.

  In the case of the above display unit, the operation keys include an operation key with a left arrow mark, an operation key with a right arrow mark, an operation key with an upward arrow mark, and a down key. And an operation key to which a direction arrow mark is attached.

  With this operation key, when a plurality of parts are arranged vertically and horizontally on the display screen, the user can easily move the parts in focus using the operation keys.

  These operation keys may be constituted by four operation keys that are independent in the left and right and up and down directions, or may be operated by moving the focus in the left and right and up and down directions in a tilting direction or operation position with one operation key configuration.

  In the case of the above-mentioned display, when moving the focus in the left-right direction, the number of the focus movement source part is calculated as plus n (where n is an arbitrary number of digits) or minus n, and when moving the focus in the vertical direction, the focus is moved. It is preferable to calculate plus (m + n) (where m is the number of digits different from n) or minus (m + n) to the number of the movement source part.

  In this calculation, for example, when n is “1” and m is “10”, the numbers of the two left and right parts are “1” and “2” on the upper side, and the numbers of the two left and right parts are “ When the operation key is operated to move the focus from the left position component to the right position component on the upper side, the focus number “1” is incremented by 1 and the component with the focus number “2” is searched. The part corresponding to this search is the part on the upper right side and is focused on this part, and the focus can be determined. When the operation key is operated to move the focus from the upper left position component to the lower left position component, the focus number “1” is incremented by 10 to search for the component with the focus number “11”. The corresponding part is the part on the left side on the lower side, and this part is focused and its focus can be determined.

  In the case of the above display, the display screen consists of a combination of the background screen and the upper screen, and the focus movement is performed on each screen by the focus movement method, while the component on either screen is the focus movement source component, When the component on the other screen is the focus destination component and the focus moves between both screens, the value assigned inside the control means is assigned to the focus destination component number set by the user as the focus destination component number. It is preferable.

  In this case, the above n is 1, the above m is 10, one screen is a background screen, the other screen is an upper screen, and the user assigns an arbitrary focus number regardless of both screens. Control means such as a computer that performs the above calculation and search when the focus number of the part is plus 1, minus 1, plus 10, or minus 10 in the arrow direction of the up / down / left / right operation keys and there is no part with the corresponding focus number Internally, since a focus number having a digit different from m and n, for example, 101 to 200 is assigned, the user can assign an arbitrary focus number to the component and move the focus without being aware of the background screen or the upper screen. It becomes like this.

  In the above case, it is preferable to provide a display screen on the display body, a bezel into which the display body is incorporated, and an operation key on the bezel.

  According to the present invention, even if there is no touch panel, the parts in the display screen can be artificially focused by operating the operation keys, and the focus can be determined by operating the enter key. Obtainable.

  The right arrow key M2 moves the focus to the right button.

  The up arrow key M3 moves the focus to the upward button.

  The down arrow key M4 moves the focus to the down button.

  The confirmation key E1 is operated to confirm the focus.

  The display screen 6 of the embodiment is configured by combining two screens, a background screen and an upper screen.

  Buttons U1, U11, U2, and U22 are displayed on the upper screen.

  Buttons D1, D11, D2, and D22 are displayed on the background screen.

  3 and 4 show a display screen 6 in which the upper screen and the background screen are combined and displayed.

  First, the setting of the arrow keys M1-M4 for the buttons U1, U11, U21, U22 on the upper screen will be described with reference to FIGS. FIG. 5 is a setting screen for setting the properties of the arrow keys M1-M4 called on the editing screen of the external PC 1. FIG. 6 is a display of the display 2 in which the properties of the arrow keys M1-M4 are set in FIG. It is a figure which shows the example of a screen. In the setting screen of FIG. 5, the screen number “001-Screen1” to be set is displayed in ScreenName. The part name (Object Name) is listed in the upper screen (Top Layer Screen). The part names are “U1”, “U11”, “U2”, and “U22”.

  In FIG. 5, the index (Index) is not “1”, “2”, “3”, “4” but “1”, “11”, “2”, “12”. That is, the button U1 has the focus number “1”, the button U11 has the focus number “11”, the button U2 has the focus number “2”, and the button U22 has the focus number “22”.

  Here, the part names “U1”, “U11”, “U2”, and “U22” are names of parts arranged on the upper screen, and are identified when the user “sets which part”. Is the name used for

  The index focus numbers “1”, “11”, “2”, and “12” are numbers that set the order of movement when the focus is moved by the arrow keys M1 to M4. Here, the operation of the arrow keys M1-M4 is determined by the numbers assigned by the user.

  When the arrow keys M1-M4 are operated, the focus of the buttons U1, U11, U2, U22 on the screen moves. The movement of the focus has a close relationship with the focus number.

  In the preview window (Preview), the objects of the buttons U1, U2, U11, U22 being set are displayed as a preview.

  In FIG. 6, the upper screen of the display screen 6 of the display is displayed. A left arrow key M1, a right arrow key M2, an up arrow key M3, and a down arrow key M4 are arranged on the bezel 2B in FIG. 6, and buttons U1, U11, U2, and U22 are displayed on the display screen 6 of the display body 2A. ing. The operations of the arrow keys M1-M4 in FIG. 6 are determined by the values set on the setting screen in FIG.

  That is, when the arrow keys M1-M4 are operated, the control means performs the calculation shown in FIG. The left arrow key M1 decreases the focus number of the focus position buttons U1, U11, U2, and U22 by 1 (-1), and the right arrow key M2 increases the focus position of the focus position buttons U1, U11, U2, and U22 by 1. (+1), the up arrow key M3 adds 10 (+10) to the focus number of the focus position buttons U1, U11, U2, U22, and the down arrow key M4 increases the focus of the focus position buttons U1, U11, U2, U22. Decrease the number by 10 (-10).

  The control unit searches the buttons U1, U11, U2, and U22 having the focus number corresponding to the calculated value, and moves the focus to the buttons U1, U11, U2, and U22 having the focus number corresponding to the calculated value.

Referring to FIG. 8, when button U1 is focused,
(1) When the right arrow key M2 is operated, the value obtained by adding 1 to the focus number “1” of the button U1 is “2”, and the button corresponding to the focus number “2” is a button arranged on the right side of the button U1. Since it is U2, the focus moves from the button U1 to U2.

 (2) When the down arrow key M4 is operated, the value obtained by adding +10 to the focus number “1” of the button U1 is “11”, and the button corresponding to this focus number is the button U11 arranged below the button U1. Thus, the focus moves from button U1 to U11.

Referring to FIG. 9, when focus is on button U2,
(1) When the right arrow key M2 is operated, the focus number “2” of the button U2 is incremented by 1 to become “3”. However, since there is no button with the focus number “3”, the control means automatically Therefore, the value is further incremented by 1 to “4”. However, since there is no button with a focus number of “4”, the control means automatically increments the value by one. As a result of the control means repeating the above, the value becomes “11”. Since this focus number is the button U11, the focus moves from the button U2 to U11.

 (2) When the down arrow key M4 is operated, the value obtained by adding +10 to the focus number “2” of the button U2 is “12”, and there is no button corresponding to this focus number. If the value is “22”, the button having the focus number of this value is U22, and the focus moves from the button U2 to U22.

 (3) When the left arrow key M1 is operated, the value obtained by decrementing the focus number “2” of the button U2 by “-1” is “1”, and the button having the focus number of this value is U1. Move from U1 to U1.

  The setting of the arrow keys M1-M4 for the buttons D1, D11, D21, D22 on the background screen will be described with reference to FIG.

  As shown in FIG. 10, the display screen 6 has a two-screen configuration of an upper screen 6a and a background screen 6b. The setting of the focus movement order at this time is not performed while viewing the screen separately on the upper screen 6a and the background screen 6b, but is performed while viewing the screen 6 that is actually displayed.

  FIG. 11 shows an example of the setting screen. The ScreenName set on the setting screen of FIG. 11 is displayed as “001-Screen1”.

  The part name (Object Name) is listed in the upper screen (Top Layer Screen) 6a. The part names are “U1”, “U11”, “U2”, and “U22”. As shown in FIG. 5, the index (Index) is not “1”, “2”, “3”, “4”, but “1”, “11”, “2”, “12”. That is, “1” is set for the button U1, “11” for the button U11, “2” for the button U2, and “22” for the button U22.

  The part name (Object Name) is listed in the background screen (Background Screen) 6b. The part names are “D1”, “D11”, “D2”, and “D22”. The index (Index) is set to “1” for the button D1, “11” for the button D11, “2” for the button D2, and “22” for the button D22.

  The same number is assigned as the focus number to the index on both the upper screen 6a and the background screen 6b. However, the control means treats the value as +100 for the number on the background screen 6b. As a result, the upper screen 6a ranges from 1-100, and the background screen 6b ranges from 101-200. This is because the allocation from 100 is easy for the user to make mistakes.

For example, as shown in FIG. 12, when the focus exists on the button U22 with the focus number “22”,
(1) When the right arrow key M2 is operated, the value obtained by adding 1 to the focus number “22” of the button U22 is “23”, and there is no button corresponding to the focus number “23”. Repeat +1 to set the next value. At this time, since there is no value greater than “23” in the range of 1-100, that is, on the upper screen 6a, the focus moves to the background screen 6b, and the first value “101” (value inside the control means) The focus moves to the button D1.

 (2) When the left arrow key M1 is operated, the value obtained by decrementing the focus number “22” of the button U22 by “−1” is “21”, and there is no button corresponding to this focus number. 1 is repeated, resulting in the value “11”. The button corresponding to this value is U11, and the focus moves from the button U22 to U11.

 (3) When the down arrow key M4 is operated, the value obtained by adding +10 to the focus number “22” of the button U22 is “32”. Since there is no button corresponding to this focus number, the focus moves to the background screen. The focus moves to the button D1, which is the first value “101” (value inside the control means).

 (4) When the up arrow key M3 is operated, the value of −10 on the focus number “22” of the button U22 is “12”, and there is no button corresponding to this focus number. The focus moves to the button U11 corresponding to “11”.

Referring to FIG. 13, when focus is on button U1 (1) When the right arrow key M2 is operated, the value is incremented by 1 to focus number “1”, so that the focus moves to button U2 with focus number “2”. .

 (2) When the left arrow key M1 is operated, the focus number “1” is decremented by 1, but there is no number less than 0 as the focus number. Therefore, the value is 200 which is the top number. However, since the focus number “200” does not exist, it is automatically searched, and as a result, the focus moves to the button D22 with the focus number “22”.

 (3) When the down arrow key M4 is operated, the value is +10, so the value is 1 + 10 = 11, and the focus moves to the button U11 with the focus number “11”.

 (4) When the up arrow key M3 is operated, the value of the focus number “1” is set to −10, but a number less than 0 is not used. Therefore, the value is 200 which is the top number. However, since 200 does not exist, it is automatically searched, and as a result, the focus moves to the button D22.

  Next, the focus number is set to (m, n), the left arrow key M1 sets m to +1, the right arrow key M2 sets m to -1, the up arrow key M3 sets n to +1, and the down arrow key M4 sets n to A function for stopping the focus in FIG. 14 and a function for ring-moving the focus in FIG. 15 will be described.

  In FIG. 14, the focus number of the button U01 is (m, n) = (0, 1), the focus number of the button U02 is (m, n) = (0, 2), and the focus number of the button U03 is (m, n). ) = (0, 3), the focus number of the button U11 is (m, n) = (1, 1), the focus number of the button U12 is (m, n) = (1, 2), and the focus number of the button U13 is (M, n) = (1,3), the focus number of the button U21 is (m, n) = (2,1), and the focus number of the button U22 is (m, n) = (2,2). In this case, the value of m and the value of n can be set independently with the arrow keys.

 (1) When the focus is on the button U01, there is no effective value even if the value of m is reduced by the arrow key, so the focus is at the same position and the focus does not move.

 (2) When the focus is on the button U21, there is no effective value even if the value of m is increased by the arrow key, so the focus is at the same position and the focus does not move.

 (3) When the focus is on the button U01, even if the value of n is increased by the arrow key, there is no effective value, so the focus is at the same position and the focus does not move.

 (4) When the focus is on the button U03, even if the value of n is increased by the arrow key, there is no effective value, so the focus is at the same position and the focus does not move. From the above, the focus can be stopped without moving.

  This will be described with reference to FIG.

 (1) When the focus is on the button U01 having the focus number (0, 1), if the value of m is incremented by +1 by the arrow key operation, the focus number becomes (1, 1), and the focus moves to the button U11. Is on the button U11 having the focus number (1, 1), the value of m is decremented by -1 by the arrow key operation, the focus number becomes (0, 1), and the focus moves to the button U1.

 (2) When the focus is on the button U11 having the focus number (1, 1), if the value of m is incremented by +1 by the arrow key operation, the focus number becomes (2, 1), and the focus moves to the button U21. Is on the button U21 having the focus number (2, 1), the value of m is decremented by -1 by the arrow key operation, the focus number becomes (1, 1), and the focus moves to the button U11.

 (3) When the focus is on the button U01 having the focus number (0, 1), when the value of m is decreased by -1 by an arrow key operation and a valid value is searched, a number having a value of m or less as the focus number is 0 not exist. Therefore, the value is the top number and the value of m is 2. As a result, the corresponding focus number is (2, 1), the focus moves to the button U21, and the focus is the focus number (2, 1). In the case of the button U21, when the value of m is incremented by 1 by the arrow key operation, there is no number having a value of m of 2 or more as the focus number. Therefore, the value is the lowest number and the value of m is 0. As a result, the corresponding focus number is (0, 1), and the focus moves to the button U01.

 (4) When the focus is on the button U01 having the focus number (0, 1), if the value of n is incremented by +1 by the arrow key operation, the focus number becomes (0, 2) and the focus moves to the button U02. Is on the button U02 having the focus number (0, 2), the value of n is decreased by -1 by an arrow key operation, the focus number becomes (0, 1), and the focus moves to the button U01.

 (5) When the focus is on the button U02 having the focus number (0, 2), if the value of n is incremented by +1 by the arrow key operation, the focus number becomes (0, 3) and the focus moves to the button U03. Is on the button U03 having the focus number (0, 3), the value of n is decreased by -1 by the arrow key operation, the focus number becomes (0, 2), and the focus moves to the button U02.

 (6) When the focus is on the button U01 having the focus number (0, 1), when the value of n is decremented by -1 by an arrow key operation and a valid value is searched, not exist. Therefore, the value is the top number and the value of n is 3. As a result, the corresponding focus number is (0, 3), the focus moves to the button U03, and the focus is the focus number (0, 3). In the case of the button U03, if the value of n is incremented by 1 using the arrow key operation, there is no number having a value of n of 3 or more as the focus number. Therefore, the value is the lowest number and the value of n is 1. As a result, the corresponding focus number becomes (0, 1), and the focus moves to the button U01. Thus, the focus can be ring-moved.

  As described above, in this embodiment, when the arrow keys M1 to M4 are operated to move the focus from an arbitrary part to another part, a calculation for adding or subtracting a predetermined value to the focus number of the arbitrary part is performed. When the part having the focus number that matches the calculated value by this execution is searched and the part that matches the search is focused, the focus can be confirmed by the operation of the confirmation key. Even without this, it is possible to obtain the same operating environment as when a touch operation is performed on a component in the display screen.
