Further, in the table stored in the control instruction storage means, the vector is set such that the moving direction and the moving amount of the predetermined display image match the direction and magnitude of the vector when the operator sees through the coordinate detection surface from the display surface side. By defining the relationship between the coordinates and the display movement amount, the operator can easily obtain a desired display image by intuitive input. Also, after inputting the coordinates of the start point of the input trajectory, each time the coordinate detecting means outputs the position coordinates of the input trajectory at fixed time intervals, the position coordinates are used as the end point position coordinates, and a predetermined display image is displayed by the display moving amount. By moving and displaying, the operator can confirm the display position of the predetermined display image moved corresponding to the input trajectory being input at regular time intervals. by this,

By moving and displaying the cursor by the moving amount of the cursor, the operator can check the display position of the cursor corresponding to the input locus being input at regular time intervals. As a result, more accurate trajectory input can be performed, and the vector can be corrected while checking the display position of the cursor corresponding to the input trajectory being input at regular time intervals.

The vector coordinate calculation means calculates the vector coordinates from the block coordinates, and the control instruction storage means stores a control instruction content corresponding to the vector coordinates represented by the block coordinates as a table.

Therefore, for one position coordinate input,

The boundary coordinate storage means stores boundary coordinates representing a boundary of a predetermined input area including an area defined by the minimum value and the maximum value detected by the input trajectory boundary coordinate detection means. The effective position coordinate determining means is a position coordinate detected by the coordinate detecting means in the execution mode, and a position coordinate in an area defined by the boundary coordinates stored in the boundary coordinate storage means is defined as an effective position coordinate. judge. The vector coordinate calculating means calculates vector coordinates based on the position coordinates determined to be valid by the valid position coordinate determining means.

Therefore, the operator can set a desired input area in the coordinate detection plane in advance, and an operator with a large hand and a long finger can set a large input area, while a small hand and a small finger can A short operator can set a small input area. Therefore, an input area where each operator can easily operate can be determined for each operator, and both can input vectors with the same operability. In addition, since a reference point such as the starting point of the input trajectory is not determined in inputting the input trajectory, the entire input area can be used effectively even if the input is within a relatively small input area, and sufficient input can be performed. You can get the quantity.

The display means reads out the image data stored in the image storage means and displays it on the display surface. The coordinate detecting means detects position coordinates of a point touched or pressed on the coordinate detecting surface. The vector coordinate calculation means calculates the coordinates of a vector formed by connecting the start point and the end point of the input trajectory of the touched or pressed point on the coordinate detection surface with a line segment. The control instruction storage means stores a control instruction content corresponding to the vector coordinates as a table. The execution means executes the control instruction content corresponding to the calculated vector coordinates with reference to the table.

Therefore, when the display surface and the coordinate detection surface are arranged at an angle of 180 ° or less, the operator can display the contents displayed on the front display surface and the coordinate detection surface.

Further, since the vector coordinates are calculated from the position coordinates of the start point and the position coordinates of the end point of the input trajectory, a desired vector can be input regardless of the input trajectory from the start point to the end point. Therefore, even when the operator makes an input from the back which cannot directly look at the input trajectory in the middle, it is not necessary to move the fingertip on the coordinate detection surface accurately from the start point to the end point in a predetermined manner, and it is stored in the control instruction storage means. The desired control instruction content can be executed by the execution means.

FIG. 7 is an explanatory diagram showing a display example of the display unit 28 when the movement of the display cursor is controlled in accordance with the input start and end point vectors in the information processing apparatus 10 according to the first embodiment of the present invention. . 7 (a), 7 (b) and 7
(C) is an explanatory view showing an example of a display on the display unit 28. FIGS. 7D and 7E are explanatory diagrams showing an example of a trajectory input by a fingertip from the rear input unit 21 as seen through from the front of the information processing apparatus 10.

In FIG. 7, a calendar for September, 1994 is displayed on the display unit. Before the input from the rear input unit 21, the screen shown in FIG. 7B is displayed.
It is assumed that the cursor is located at the position of the fifth day. FIG. 7 (a)
7B shows a screen displayed on the display unit 28 as a result of the input of the trajectory shown in FIG. 7D from the rear input unit 21 when the screen of FIG. 7B is displayed on the display unit 28. . FIG.
As shown in FIG. 7A, when the screen shown in FIG. 7B is displayed, the cursor is moved from the position on the 15th to the position on the 4th by inputting the trajectory shown in FIG. I do.

When the screen shown in FIG. 7B is displayed, the cursor moves from the position on the 15th to the position on the 24th by inputting the trajectory shown in FIG.

FIG. 8 is a table showing an example of correspondence between input start and end point vectors and display cursor movement units in the information processing apparatus 10 according to the first embodiment of the present invention. Here, the cursor movement unit on the display unit 28 is, for example,
As shown in the arrangement of the dates on the calendar in FIG. 7A, when the display positions of the cursors are arranged in a matrix on the display surface of the display unit 28, when the display unit 28 is viewed from the front, Moving one is (+1,0), moving one to the left is (-1,0), moving one down is (0, + 1), moving one up is (0, -1). ).

The display controller 26 stores the table shown in FIG. 8 in the control memory 29, and determines the display cursor movement unit corresponding to the input start / end point vector according to the table shown in FIG. For example, in the input example shown in FIG. 7D, it is assumed that the position coordinates of the start point A are A (0,1) and the position coordinates of the end point B are B (4,0). The input start and end point vectors are B (4,0) -A (0,1) = AB (+ 4,-
1), and the cursor movement unit is (-4, -1) from the table shown in FIG. In the input example shown in FIG. 7E, the position coordinates of the start point A are A (4, 1), and
It is assumed that the position coordinates of the end point B are B (2, 2). The input start / end point vector is B (2,2) -A (4,1) = AB
(−2, +1) is calculated, and the unit of movement of the cursor is (+2, +1) from the table shown in FIG.

When the cursor movement unit indicated by the input start / end point vector exceeds the range in which the cursor can be moved in the display unit 28, the cursor does not move any further. For example, when the screen shown in FIG. 7B is displayed on the display unit 28 and a locus such that the input start / end point vector is calculated as (−4, +1) is input from the rear input unit 21. Indicates that the cursor movement unit is (+4, +1) from the table shown in FIG.
The cursor position displayed at the top is 24 shown in FIG.

Also, the input start / end point vector is (0,0)
When the trajectory calculated as is input, that is, when the fingertip touches the rear input unit 21 and moves away without moving, it means that the selection determination operation has been performed at the current cursor position. . For example, if this operation is performed when the cursor is located at a certain date on the calendar, a selection decision is made such that a detailed schedule for that date is displayed. Alternatively, the selection in application selection or processing content selection can also be performed by this operation.

FIG. 9 is a flowchart for explaining a processing procedure when the movement of the display cursor is controlled in accordance with the input start and end point vectors in the information processing apparatus 10 according to the first embodiment of the present invention. After turning on the power, the CPU 14
The control program of the information processing device 10 is read from M15 and executed. As a result, the display control program is executed, the display control unit 26 is activated, and the ROM 1
5 and parameters related to display according to the application, such as cursor position coordinates, are read from the RAM 16 into the control memory 29. Further, the display image storage unit 2
7, the image data of the initial screen for selecting an application is read into the display unit 28, and the application selection screen is displayed. When the operator performs a key input from the key input unit 25 in accordance with an input instruction on the application selection screen, one of the applications of the information processing apparatus 10 is
One is selected (step S901).

If the selected application is a calendar display or an application that moves to the next process from the calendar display screen (step S902), the image data of the calendar initial screen is read into the display image storage unit 27 (step S903). ), Display unit 28
Displays the initial screen of the calendar (step S90)
4).

When the operator performs a key input from the key input unit 25 in accordance with the input instruction displayed on the initial screen of the calendar, the next process to be started from the initial screen of the calendar is selected (step S905). . If the selected processing content is a content for instructing cursor movement based on fingertip input (step S906), the back input unit 21 is activated, and the position coordinates of the input trajectory from the back input unit 21 are changed at regular intervals. Is input to the coordinate data quantization unit 23 (step S907).

The display control unit 26 detects the presence or absence of an input from the back input unit 21 to the coordinate data quantization unit 23 at regular intervals, and if there is an input of the position coordinates from the back input unit 21 (step S908). , The input position coordinates are quantized by the coordinate data quantization unit 23 (step S90).
9). If the position coordinates input from the coordinate data quantization unit 23 to the input start / end point vector calculation unit 24 are the position coordinates of the start point of the input trajectory, the position coordinates are stored in the coordinate memory 30. After the position coordinates of the start point of the input trajectory are stored in the coordinate memory 30, the input start / end point vector calculation unit 24 sets the position coordinates input from the coordinate data quantization unit 23 as the position coordinates of the end point of the input trajectory. The input start / end point vector is calculated from the start point position coordinates stored in the memory 30 (step S910).

The display control unit 26 obtains a cursor movement unit corresponding to the calculated input start / end point vector with reference to the table shown in FIG. 8 (step S911). The display control unit 26 obtains the display position of the cursor on the display unit 28 when the cursor is moved from the initial position by the cursor movement unit obtained in step S901 in the same manner as in the related art, and after moving the cursor to the obtained display position. Is output to the display image storage unit 27. The display unit 28 displays the image data in the display image storage unit 27, and the information processing device 10 returns to the process of step S907 (step S912).

In step S908, if there is no input of the position coordinates of the start point of the input trajectory, the display control unit 26 keeps the state and waits for input from the rear input unit 21. If there is no input in step S905, the process returns to step S905. In step S906, if the processing content selected in step S905 does not instruct cursor movement on the display screen, for example, a schedule input screen is displayed for a date on which the cursor is already positioned at that time. In the case of instructing the processing content, the information processing device 10
Performs the instructed process (step S913), and then returns to the process of step S905.

If, in step S902, an application started from the initial screen other than the calendar is selected in step S901, the information processing apparatus 10 performs the processing of the selected application, and returns to the processing in step S901. (Step S914). In step S901 or step S905, application selection and processing content selection are performed by key input. In this step, the back side input unit 21 has already been activated, and the processing procedure is performed so that menu selection can be determined by back side input. It is easy to change.

FIG. 11 is a table showing an example of the correspondence between the input start / end point vector, the page turning unit, and the scroll unit in the information processing apparatus 10 according to the first embodiment of the present invention. The display control unit 26 stores the table shown in FIG. 11, and determines a page turning unit and a scroll unit corresponding to the input start and end point vectors according to the table of FIG. For example, as shown in FIG. 10H, if the position coordinates of the start point of the fingertip input are (0, 1) and the position coordinates of the end point are (4, 0), the input start and end point vector is (4, 0). − (0, 1) = (+ 4, −1),
Four pages are returned from the table shown in FIG.

For example, as shown in FIG. 10 (g), if the position coordinates of the start point of the fingertip input are (4, 2) and the position coordinates of the end point are (0, 1), the input start and end point vector is (0,1) − (4,2) = (− 4, −1),
Four pages are turned from the table shown in FIG. For example, as shown in FIG. 10I, if the position coordinates of the start point of the fingertip input are (2, 0) and the position coordinates of the end point are (1, 2), then the input start and end point vector is (1, 0). 2)
− (2, 0) = (− 1, +2) is calculated, and two blocks of the detection block are scrolled downward from the table shown in FIG.

FIG. 12 is an explanatory diagram showing an example of the correspondence between the input start and end point vectors in FIG. 11 and the unit of page turning and the unit of scrolling on (x, y) coordinates. The (x, y) coordinates shown in FIG. 12 are the same as the (x, y) coordinates set on the detection surface of the rear input unit 21 in FIG.
2, the right direction is the positive direction of the x-axis, and the left direction is the positive direction of the y-axis. In FIG. 12, a portion indicated by a diagonally lower left diagonal line indicates a region of an input start / end point vector corresponding to page turning, and a portion indicated by a diagonally lower right line indicates a region of an input start / end point vector corresponding to scrolling. . For scroll direction,
The downward direction is represented by positive and the upward direction is represented by negative. The direction of page turning is indicated by a negative sign indicating that the page should be turned back.
Sending a page is indicated by a positive sign.

As shown in FIG. 12, the input start and end point vectors in the left and right directions with respect to the detection plane are inputs for specifying the direction and amount of page turning, and the input start and end vectors in the vertical direction with respect to the detection plane. Is an input for instructing the direction and amount of scrolling. In addition, as the amount of movement of the fingertip increases in both the vertical and horizontal directions, the input is an instruction to instruct a larger amount of scrolling and page turning. In this case, particularly with respect to the fingertip input in the x-axis direction, as the amount of movement of the fingertip in the fingertip input increases, the displacement in the direction orthogonal to the direction of the input trajectory, that is, in the y-axis direction increases. . Therefore, a larger area in the y-axis direction is assigned to the area of the input start / end point vector instructing page turning of three or more pages than the area of the input start / end point vector instructing page turning of two or less pages. . y
The same applies to the area of the input start / end point vector in the axial direction.

Here, since the operator of the information processing apparatus 10 faces the display surface of the display unit 28, the input trajectory to the rear input unit 21 which cannot perform input while looking directly at the back is:
From the operator's point of view, the input trajectory is regarded as an input trajectory when the operator sees through the detection surface from the display surface side. Therefore, FIG.
By controlling the page turning based on the table shown in FIG. 1, it is understood for the operator that the direction of the input trajectory matches the direction of scrolling or page turning.

As described above, the information processing apparatus 1 of this embodiment
According to 0, the direction and length of the input trajectory are associated with changes in the displayed contents such as the moving direction and moving distance of the cursor, the direction of page turning and the number of pages, the direction of scrolling and the amount of scrolling, respectively. In addition, it is not necessary to perform complicated procedures, and an intuitive operation input can be easily performed.

Further, the information processing apparatus 10 of the present embodiment
Since the movement amount of the display content of the display unit 28 is determined from the coordinates of the start point and the end point of the fingertip input to the back input unit 21, the desired input start / end point vector is set regardless of the input trajectory from the start point to the end point. Can be entered. Therefore, the desired display control can be easily performed even when the operator inputs a fingertip from the rear input unit 21 that cannot directly view the input trajectory in the middle.

According to the information processing apparatus 10 of this embodiment, after inputting the coordinates of the starting point of the input trajectory,
Whenever 1 outputs the position coordinates of the input trajectory at fixed time intervals, the position coordinates are used as the end point position coordinates, and display control is performed based on the input start and end point vectors. The amount of change in the displayed content can be checked at regular time intervals. Thereby, more accurate fingertip input can be performed, and the input start and end point vectors can be corrected at any time as long as the fingertip is not released from the rear input unit 21. The input start and end point vectors can be corrected while confirming the amount of change in the displayed content at regular time intervals, and desired display control can be obtained more quickly.

As shown in FIG. 6, the concave portion 32 is provided at a position where the index finger can reach the detection surface of the rear input section 21 provided at the upper portion of the rear surface when the thumb is placed in the concave portion 32 and the main body 31 is held. . By providing the recess 32 in this manner, the main body 31 can be stably held with one hand even during fingertip input, and positioning of the main body 31 at the time of fingertip input, such as a holding angle, can be easily performed. No matter when fingertip input is performed, the same input result as usual can be obtained.

Further, as shown in FIG. 5, the detection surface of the rear input unit 21 is located recessed from the rear surface of the main body 31, so that the operator cannot directly look at the detection surface.
By touching with the fingertip, the boundary between the rear surface of the main body 31 and the detection surface of the rear input unit 21 can be easily recognized, so that the intended fingertip input can be easily performed. In this embodiment, the recess 32 for the thumb guide is used.
Has been described on the left side, but the same effect can be obtained by providing on the right side.

In this embodiment, the case where the input trajectory by the fingertip is not displayed on the display unit 28 has been described. The same effect can be obtained by displaying the input trajectory on the display unit 28 so that the coordinates can be confirmed. In this embodiment, cursor movement, page turning, and screen scrolling have been described as examples of control of display contents. However, the control contents according to this embodiment are not limited to the above-described examples. For example, in response to a fingertip input from the back input unit 21 described above,
Similar effects can be obtained even when other display control is performed, such as enlargement / reduction of the display image, movement of the viewpoint of the display image, and the like.

The size of the minimum rectangular area in which the length of each side of the detection block 141 in the X-axis direction and the Y-axis direction is an integer value is determined. Further, the boundary coordinates of the rectangular area whose size is determined are, for example, described in the rectangular area (Xmin,
Ymin) and (Xmax, Ymax) are determined to be located at the center of the rectangular area. As described above, FIG.
4 (a), the boundary coordinates (XL, YL) and (XH, YH) of the designated input area C1 indicated by the dashed line are defined.

Similarly, when the input trajectory L1 shown in FIG. 14B is input to the rear input unit 21, the minimum value Xmin and the maximum value of the X-axis coordinate in the position coordinate series indicating the input trajectory L2 are similarly obtained. Xmax and minimum value Ym of Y axis coordinate
The boundary coordinates (XL, YL) and (XH, YH) of the designated input area C2 are determined from in and the maximum value Ymax. In the fingertip input mode, the input area determination unit 131 outputs a position coordinate series from the back input unit 21 by fingertip input.
If the position coordinates (X, Y) satisfy XL ≦ X <XH, YL ≦ Y <YH, the position coordinates (X, Y) are made valid; otherwise, the position coordinates (X, Y) are made invalid. .

The coordinate data quantizing unit 133 divides the input area determined as described above into a total of 20 detection blocks obtained by dividing the input area into five equal parts in the X-axis direction and four equal parts in the Y-axis direction. The position coordinates in the input area for which the boundary coordinates are determined by the unit 131 are converted into position coordinates (x, y) quantized in units of the detection block. For example, the coordinate data quantizing unit 133 divides the designated input area C1 determined by the input area determining unit 131 into a total of 20 detection blocks obtained by equally dividing the specified input area C1 into five in the X-axis direction and four in the Y-axis direction. The detection block 141 is divided, and the position coordinates (X, Y) in the designated input area C1 are converted into position coordinates (x, y) quantized in units of the detection block 141. In the detection block, the upper left corner is a (0,0) block and the lower right corner is a (4,3) block when the rear input unit 21 is viewed from the rear side.

The coordinate data quantization unit 133 calculates (X, Y)
Assuming that the size of the detection block on the coordinates is LX × LY and the quotient when A is rounded down and divided by B is a function g (A / B), the boundary coordinates (XL, XL,
The position coordinates (X, Y) in the input area represented by (YL) and (XH, YH) are converted into quantized position coordinates (x, y) based on the following equation.

X = g {(X−XL) / LX}, Y = g
{(Y−YL) / LY} In this way, the position coordinates (X, Y) are changed to the position coordinates (x,
After the conversion into y), the input start / end point vector output by the input start / end point vector calculation unit 24 has the same value as that described in FIG. However, it is different from the case of the first embodiment that the area shown as the rear input unit 21 in FIG. 4 shows the input area determined as described above in the second embodiment.

FIG. 15 is a flowchart for explaining a processing procedure in the input area setting mode in the information processing apparatus 130 according to the second embodiment of the present invention. Display control unit 134
Starts the input area setting mode based on a key input from the key input unit 25. The operator of the information processing device 130 inputs a trajectory for setting an input area from the rear input unit 21 according to the input instruction displayed on the display unit 28 in the input area setting mode. The input area determination unit 131 detects a maximum value Xmax, a minimum value Xmin of the X coordinate, a maximum value Ymax of the Y coordinate, and a minimum value Ymin from the position coordinate series output from the back input unit 21 at regular intervals, It is stored in the boundary coordinate memory 136 (step S151).

The display control section 134 detects the end of the input in the input area setting mode, and instructs the input area determination section 131 to calculate the size of the detected block and the boundary coordinates of the input area (step S152). The input area determination unit 131 determines the maximum value Xmax, the minimum value Xmin, and the maximum value Ymax of the X coordinate stored in the boundary coordinate memory 136.
x, from the minimum value Ymin, the boundary coordinates (Xmin, Ymi
n), a rectangular area including a rectangular area represented by (Xmax, Ymax), and the rectangular area is defined by 5 in the X-axis direction.
The size of the minimum rectangular area is calculated such that when equally divided into four in the Y-axis direction and divided into a total of 20 detection blocks, the size of the detection blocks becomes an integer value. Further, the size of the detection block is calculated and output to the boundary coordinate memory 136 (step S153).

The input area judging section 131 sets the boundary coordinates (Xmin, Ymin), (Xmax,
The boundary coordinates (XL, YL) and (XH, YH) of the rectangular area are calculated and output to the boundary coordinate memory 136 so that the rectangular area represented by (Ymax) is located. Accordingly, the display control unit 134 ends the input area setting mode (Step S154).

After that, the display control section 134 starts the fingertip input mode. The input area determination unit 131 determines whether the position coordinates (X, Y) input from the rear input unit 21 to the coordinate data quantization unit 133 at regular time intervals are valid / invalid.
The coordinate data quantization unit 133 reads data necessary for the operation for quantization from the boundary coordinate memory 136, and the position coordinates (X, Y) from the rear input unit 21 determined to be valid by the input area determination unit 131. To the position coordinates (x, y)
Quantize to

Will be Therefore, while an operator with a large hand and a long finger can take a large input area, even if an operator with a small hand and a short finger cannot take a large input area, an input area that can be easily operated is set. The same display contents can be obtained with the same operability in both cases.

Further, since the reference point such as the starting point of the input trajectory is not defined in the rear input unit 21, a sufficient input amount can be obtained even if the input is within a relatively small input area. That is, regarding the example of the cursor control described with reference to FIGS. 7 and 8, regardless of the size of the input area, in order to move the four-unit cursor to the right on the display unit 28, When viewed from the back side, the input area may be traced from the right end to the left end with a finger. To move the three-unit cursor downward, the input area may be traced from the upper end to the lower end.

Therefore, when the back connection information is “H”, the fingertip input to the input unit 171 is the back input as seen from the operator, as in the first embodiment, and when the back connection information is “L”, the input unit 171 is input. Is a face-to-face input from the viewpoint of the operator.

FIG. 19 is a rear view and a right side view of an information processing apparatus 160 according to a third embodiment of the present invention. FIG.
As shown in FIG.
A back surface connection detecting unit 173 is provided in a concave portion 193 provided on the back surface of 81. Also, the information processing device 160
A protrusion 192 is provided on the rear surface of the unit 182 at a position corresponding to the recess 193. When the first unit 181 and the second unit 182 are angularly displaced around the hinge 183, and the protrusions 192 are arranged such that their back surfaces are in contact with each other as shown in FIG.

63 detects whether the back of the first unit 181 and the back of the second unit 182 are in contact with each other. When operating the information processing apparatus 160, FIG.
In the state shown in FIG. 8A, the operator holds the second unit 182 with his / her left hand, or places the second unit 182 on a desk, and puts the input unit 171 with a pen or fingertip with his / her right hand. Face-to-face input. At this time, texts and images corresponding to the application of the information processing apparatus are displayed on the display unit 28, and the second display unit 174 superimposed on the input unit 171 displays the detection block classification, software switch, Information related to the input, such as an input instruction and an input locus, is displayed.

In the state shown in FIG. 18B, the operator holds the side of the first unit 181 and the second unit 182 with the thumb, ring finger and little finger of the left hand, for example. Input part 17 on the back with middle finger
The fingertip input is performed by tracing the surface of No. 1. In this case, no display is performed on the second display unit 174. Then
Hereinafter, a method in which the display control unit 172 controls the display screen of the display unit 28 based on the back connection information from the back connection detection unit 173 and the input start and end point vectors from the input data processing unit 22 will be described. The case of page turning control and scroll control will be described.

As shown in FIG. 18B, when the back of the first unit 181 is in contact with the back of the second unit 182, that is, when the back connection information is “H”,
Display unit 2 corresponding to the input start / end point vector by fingertip input
8 are controlled by the cursor movement control described with reference to FIGS. 7, 8 and 9 in the first embodiment, and the page turning control and scrolling described with reference to FIGS. 10, 11 and 12. The description is omitted because it is the same as the control.

On the other hand, as shown in FIG.
When the back surface of the first unit 181 and the back surface of the second unit 182 are not in contact with each other, that is, when the back connection information is “L”, the operator performs the input in the state shown in FIG. When the same trajectory as the fingertip input to the unit 171 is face-to-face input from the input unit 171, the input start and end point vector of the input trajectory is compared with the input start and end point vector by the fingertip input, and the coordinate value of the Y-axis coordinate is The sign is reversed.

The reason for this is that the position coordinates output by the input unit 171 are the same as those shown in FIG. 18A even if the positional relationship between the first unit 181 and the second unit 182 is as shown in FIG.
This is because, even in the state shown in (b), if the point where the pen tip or the fingertip touches on the input unit 171 is the same, the position coordinates output from the input unit 171 are the same. That is, in the state shown in FIG.
When the input unit 171 is viewed from the front, the lower right corner of the input unit 171 corresponds to (0, 0), the X-axis coordinate increases toward the left, and the Y-axis coordinate increases upward, that is, the first coordinate. It increases as approaching the unit 181. Therefore, when performing quantization at 5 levels in the X-axis direction and 4 levels in the Y-axis direction, the detection block at the lower right corner of the input unit 171 is (0, 0) in the state shown in FIG. The detection block at the upper left corner corresponds to (4, 3).

FIG. 20 is a table showing an example of correspondence between an input start / end point vector by face-to-face input and a display cursor moving unit in the information processing apparatus 160 according to the third embodiment of the present invention. FIG. 21 is a table showing an example of correspondence between input start / end point vectors by face-to-face input and units of page turning and scrolling in the information processing apparatus 160 according to the third embodiment of the present invention.

For the above reason, as shown by hatching in each of FIG. 20 and FIG.
When the first and second units 182 are in the state shown in FIG. 18A, the unit of movement of the display cursor on the display unit 28, the unit of page turning, and the scrolling with respect to the input start / end point vector input from the input unit 171. Are the Y units of the display cursor movement unit, the page turning unit, and the scroll unit shown in FIGS. 8 and 11.
The coordinate values obtained by reversing the sign of the axis coordinates are shown.

[0127] The display control unit 172 is
3 based on the rear connection information from the first unit 181.
It is determined whether the rear surface of the second unit 182 is in contact with or separated from the rear surface of the second unit 182.
The display content of the display unit 28 is controlled based on the table shown in FIG. 21 and FIG.
The display content of the display unit 28 is controlled based on the table shown in FIG.

As a result, the input trajectory face-to-face input from the input unit 171 in the state shown in FIG.
If the input trajectory of the fingertip input from the input unit 171 in the state shown in (b) is the same as the input trajectory seen through from the operator side, the same display control is performed corresponding to the two input trajectories. . Therefore, for the operator, the first unit 181
18A and the second unit 182 are in the state shown in FIG. 18A and the state shown in FIG.
8 can be displayed. Therefore, the operator can
The unit 181 and the second unit 182 are shown in FIG.
18B and the state shown in FIG. 18B, desired display contents can be easily obtained.

Here, two tables, one where the back of the first unit 181 and the back of the second unit 182 are in contact with each other and the case where they are separated from each other, are used for cursor movement control, scroll control, and page turning control. 20 and FIG. 21 are stored.
When the back connection information is “L” without using the table shown in (1), the y coordinate of the input start / end point vector input face-to-face is multiplied by “−1” to obtain the y coordinate of the input start / end point vector input face-to-face. The negative sign may be inverted and the tables shown in FIGS. 8 and 11 may be referred to.

FIG. 22 is a flowchart for explaining a processing procedure relating to cursor movement control of the information processing apparatus 160 according to the third embodiment of the present invention. After power on, CPU1
4 reads the control program of the information processing device 160 from the ROM 15 and executes it. Accordingly, the display control program is executed, and the display control unit 172 is activated. At this time, if the back connection information from the back connection detection unit 173 is “L” (step S2201), parameters related to display according to the application, such as cursor position coordinates, are read from the ROM 15 and the RAM 16 into the control memory 175. . Furthermore, image data such as an initial screen and software keys for selecting an application is read from the ROM 15 into the display image storage unit 27, and an application selection screen and software keys are displayed on the display unit 28 and the second display unit 174. According to the input instruction on the application selection screen, the operator presses the software key displayed on the second display unit 174, thereby selecting one of the applications of the information processing device 160 (step S2202).

If the application selected by the software key input is an application for moving to the next process from the calendar display or the calendar display screen (step S2203), the image data of the initial screen of the calendar is read into the display image storage unit 27. At the same time (step S2204), an initial screen of the calendar is displayed on the display unit 28 (step S2205).

A software key for selecting the next processing content started from the initial screen of the calendar is displayed on the second display section 174 (step S2206), and when the operator presses the software key, the calendar is initialized. Next processing content started from the screen is selected (step S2207). If the selected processing content is a content for instructing cursor movement based on the face-to-face input (step S2208), the detection block classification for face-to-face input is displayed on the second display unit 174 (step S220).
9) The position coordinates of the input trajectory by the face-to-face input from the input unit 171 are input to the coordinate data quantization unit 23 at regular intervals (step S2210).

The display control unit 172 detects the presence or absence of an input from the input unit 171 to the coordinate data quantization unit 23 at regular intervals, and if there is an input of the position coordinates from the input unit 171 (step S2211), the process proceeds to step S2211. As in step S909 shown in FIG. 9, the input position coordinates are quantized by the coordinate data quantization unit 23 (step S2212). As in step S910 shown in FIG. 9, the position coordinates of the start point of the input trajectory are stored in the coordinate memory 30, and the input start and end point vectors are calculated (step S2213).

The display control section 172 refers to the table shown in FIG. 20 to find a cursor movement unit corresponding to the calculated input start / end point vector, and moves the cursor movement unit from the initial position by the found cursor movement unit in the same manner as in the related art. Then, the display position of the cursor on the display unit 28 at the time is calculated. Display control unit 17
2 outputs the image data after the cursor is moved to the obtained display position to the display image storage unit 27, and the display unit 28 displays the image data in the display image storage unit 27 (step S).
2215).

If it is determined in step S2211 that the position coordinates of the start point of the input trajectory have not been input yet, the display control unit 172 holds the state and waits for input from the input unit 171. If there is no input within the set time, the process returns to step S2206.
In step S2208, if the processing content selected in step S2207 does not instruct cursor movement on the display screen, for example, a schedule input screen is displayed for a date on which the cursor is already positioned at that time. When the instruction is to instruct processing contents, the information processing apparatus 160 performs the instructed processing (step S2217), and then returns to the processing in step S2206.

In step S 2203, if an application started from the initial screen other than the calendar is selected in step S 2202, information processing apparatus 160 performs processing of the selected application (step S 2218), and step S 2201 Return to the processing of. If the back connection information is “H” in step S2201, the process is performed according to the procedure shown in the flowchart of FIG. 9 (step S2219), and step S2219 is performed.
Return to 2201.

As described above, the information processing apparatus 1 of this embodiment
According to 60, for the operator, regardless of whether the first unit 181 and the second unit 182 are in the state shown in FIG. 18A or the state shown in FIG. Desired display contents can be obtained from the input image, and the moving direction and scroll direction of the display cursor match the direction of the input trajectory. Further, the direction of page turning corresponds to the direction of the input trajectory corresponding to the general left opening in books and notes. Thereby, the operator can intuitively grasp the change of the display content corresponding to the input locus to the input unit 171. Therefore, the information processing apparatus 160 can perform not only the back side input while holding the main body with one hand but also the display control with excellent operability for the operator.

In the present embodiment, the back connection detecting section 1
73 uses the pressure sensor 163,
73 is, for example, the convex portion 19 in addition to the pressure sensor 163.
2 are connected by pressing the bottom surface of the concave portion 193, and the first end is connected / disconnected by a switch that is disconnected when the convex portion 192 and the concave portion 193 are separated from each other.
It may be detected whether the back surface of the unit 181 is in contact with the back surface of the second unit 182.

[0139] Further, the back connection detecting section 173 transmits, for example, a light source such as a photodiode at the position of the concave portion 193 instead of the concave portion 193 and a light from the light source at the position of the convex portion 192 instead of the convex portion 192. A first unit 181 and a second unit 1
When the back surfaces of the first and second units 82 and 182 are in contact with each other, the light from the light source is detected by the photo sensor to determine whether the back surface of the first unit 181 and the back surface of the second unit 182 are in contact with each other. Good.

Further, in this embodiment, the first unit 181 and the second unit 182 are arranged such that the surface of the display unit 28 and the surface of the input unit 171 are on the short side, respectively. Although the case where the side surfaces are connected via the hinge 183 has been described, the same effect can be obtained when the long side surfaces of both units are connected via the hinge 183. However, in this case, the positive and negative X coordinate values of the input start and end point input start and end point vectors in the case of the back side input and the case of the face-to-face input are opposite to each other.

In the information processing apparatus according to the present invention, for example, the software key corresponding to the coordinates of the software key displayed on the display unit 28 is stored in the arithmetic control memory in the arithmetic processing unit for performing the numerical operation. Is stored on the software key based on the input start / end point vector by the fingertip input, and the cursor is positioned in the arithmetic processing unit when the fingertip input is completed. The numerical value of the software key can be input as data, and the numerical value can be processed in accordance with the calculation instruction indicated by the software key. Similarly, in the control memory in the control unit for controlling the operation of the entire information processing apparatus, in correspondence with the coordinates of the software key displayed on the display unit 28, the application options and the return key indicated by the software key are displayed. By storing a control instruction such as, and moving the cursor on the software key based on the input start and end point vector, the control unit according to the control instruction of the software key where the cursor is located when the fingertip input ends , The selected application can be executed.

For example, when inputting data such as numerical values based on an input start / end point vector by a fingertip input,
As described above, in correspondence with the coordinates of the software key displayed on the display unit 28, the numerical value indicated by the software key, the operation instruction, and the like are stored in the operation control memory in the operation processing unit that performs the operation of the numerical value. Instead, numerical values and calculation instructions may be stored in direct correspondence with the input start and end point vectors by fingertip input.

In this embodiment, the information processing apparatus has been described. However, the present invention is not limited to the information processing apparatus, but may be applied to a remote controller such as a television and an air conditioner.

[0144]

As described above, according to the information processing apparatus according to the first aspect, the operator inputs the input trajectory from the coordinate detection surface arranged on the back with the finger of the hand holding the side of the information processing apparatus. Is input, and the execution means can execute desired control instruction contents from among the control contents stored in the control instruction storage means. Further, since the vector coordinates are calculated from the position coordinates of the start point and the position coordinates of the end point of the input trajectory, a desired vector can be input regardless of the input trajectory from the start point to the end point. Therefore, even when the operator makes an input from the back, which cannot directly view the input trajectory in the middle, it is not necessary to accurately move the fingertip on the coordinate detection surface from the start point to the end point in a predetermined manner, and the desired control instruction is executed. Means can be implemented.

Further, according to the information processing apparatus of the second aspect, the operator holds the side of the information processing apparatus with his / her finger on the back while watching the display contents displayed on the front display surface. An input trajectory can be input from the arranged coordinate detection surface. Further, in the table stored in the control instruction storage means, the vector is set such that the moving direction and the moving amount of the predetermined display image match the direction and magnitude of the vector when the operator sees through the coordinate detection surface from the display surface side. By defining the relationship between the coordinates and the display movement amount, the operator can easily obtain a desired display image by intuitive input. Also, after inputting the coordinates of the start point of the input trajectory, each time the coordinate detecting means outputs the position coordinates of the input trajectory at fixed time intervals, the position coordinates are used as the end point position coordinates, and a predetermined display image is displayed by the display moving amount. By moving and displaying, the operator can confirm the display position of the predetermined display image moved corresponding to the input trajectory being input at regular time intervals. With this, a more accurate trajectory can be input, and the vector can be corrected at any time as long as the fingertip is not released from the coordinate detection surface, so that the trajectory is moved according to the input trajectory being input. The vector can be corrected while checking the display position of the predetermined display image at regular time intervals, and a desired display image can be obtained more quickly.

According to the information processing apparatus of the present invention, in the table stored in the control instruction storage means, the moving direction and the moving amount of the cursor and when the operator sees through the coordinate detection surface from the display surface side. By defining the moving direction and moving amount of the cursor corresponding to the vector coordinates so that the direction and size of the vector match,
The operator can easily display the cursor at a desired position by intuitive input. Also, after the coordinates of the start point of the input trajectory are input, each time the coordinate detecting means outputs the position coordinates of the input trajectory at fixed time intervals, the position coordinates are used as the end point position coordinates, and the cursor corresponds to the vector coordinates. By moving and displaying the cursor by the moving amount of the cursor, the operator can check the display position of the cursor corresponding to the input locus being input at regular time intervals. As a result, more accurate trajectory input can be performed, and the vector can be corrected while checking the display position of the cursor corresponding to the input trajectory being input at regular time intervals. Can display a cursor.

According to the information processing apparatus of the fourth aspect, in the table stored in the control instruction storage means, the scroll amount of the display screen and the vector when the operator sees through the coordinate detection surface from the display surface side. The scroll amount of the display screen corresponding to the vector coordinates is determined so that the vertical components of the vector coincide with each other, the page turning amount of the display screen, and the horizontal direction of the vector when the operator sees through the coordinate detection surface from the display surface side By determining the page turning amount corresponding to the vector coordinates so that the components match, the operator can easily display a desired display line and a desired page by intuitive input. Also, after the coordinates of the start point of the input locus are input, every time the coordinate detecting means outputs the position coordinates of the input locus at fixed time intervals, the position coordinates are used as the position coordinates of the end point, and the display screen is scrolled or turned. By moving the display by the amount, the operator can check the display line or the display page corresponding to the input trajectory being input at regular time intervals. As a result, more accurate trajectory input can be performed, and the vector can be corrected while checking the display line or display page corresponding to the input trajectory being input at regular time intervals. A display line or a display page can be displayed.

Further, according to the information processing apparatus of the fifth aspect, the input of one position coordinate has a wide spread.
Since an area of one coordinate detection block is allocated, accurate input with a small input error can be performed, even though the input is from a coordinate detection plane that cannot be viewed directly. According to the information processing apparatus of the sixth aspect, the operator can determine a desired input area in the coordinate detection plane in advance, and an operator with a large hand and a long finger can set a large input area. On the other hand, an operator with a small hand and a short finger can set a small input area. Therefore, an input area where each operator can easily operate can be determined for each operator, and both can input vectors with the same operability. Also, in inputting the input trajectory,
Since the reference point such as the starting point of the input trajectory has not been determined,
Even if the input is made within a relatively small input area, the entire input area can be used effectively, and a sufficient input amount can be obtained.

According to the information processing apparatus of claim 7, in addition to the above effects, the same effect as that of the information processing apparatus of claim 5 can be obtained. According to the information processing apparatus of claim 8, when the operator holds the information processing apparatus with the thumb positioned in the recess, the index finger is provided on the back of the coordinate detection surface. The information processing device can be stably held with one hand even during input of the input trajectory, and positioning of the information processing device at the time of input of the input trajectory, such as the holding angle, can be performed. Since the input operation can be easily performed, the input operation can be started in a short time after being held, and the same input result can be obtained no matter when the input is performed.

According to the information processing apparatus of the ninth aspect, when the display surface and the coordinate detection surface are arranged at an angle of 180 ° or less, the operator can display the information on the front display surface. While looking at the displayed content and the coordinate detection surface, input an input trajectory facing the coordinate detection surface, and when the rear surface of the first unit and the rear surface of the second unit are arranged in contact with each other, While looking at the display content displayed on the front display surface, input the input locus from the coordinate detection surface arranged on the back with the finger of the hand holding the side of the information processing device, and store the input locus in the control instruction means. The desired control instruction content can be executed by the execution means. Therefore, the information processing apparatus of the present invention can receive the input from the back and the input from the facing by one coordinate detecting means, and can compare with the case where the input device is provided on both the back and the facing of the information processing apparatus. As a result, an information processing device capable of one-handed input can be realized at low cost. Also, since the vector coordinates are calculated from the position coordinates of the start point and the position coordinates of the end point of the input trajectory, regardless of the input trajectory on the way from the start point to the end point,
A desired vector can be input. Therefore, even when the operator makes an input from the back which cannot directly look at the input trajectory in the middle, it is not necessary to move the fingertip on the coordinate detection surface accurately from the start point to the end point in a predetermined manner, and it is stored in the control instruction storage means. The desired control instruction content can be executed by the execution means.

According to the information processing apparatus of the tenth aspect, in addition to the above-mentioned effects, when the first unit and the second unit are in contact with the back, the input from the coordinate detection surface on the back side is input. A vector obtained based on the trajectory obtained by seeing through from the front, and a vector obtained based on the input trajectory input from the coordinate detection surface on the front when the first unit and the second unit are not in contact with the back. If the vector is the same, the storage contents of the two tables are determined so that the same control instruction content or the same display movement amount can be obtained.
Regardless of whether or not the unit is in contact with the back surface, the same control result can be obtained with the same input feeling. Thereby, the operator easily causes the execution unit to execute the desired control instruction content stored in the control instruction storage unit, regardless of whether the first unit and the second unit are in contact with the back surface, Alternatively, a desired display image can be displayed on the display means.

According to the information processing apparatus of the eleventh aspect, in addition to the above-mentioned effects, in the table stored in the control instruction storage means, the moving direction and the moving amount of the predetermined display contents, and By defining the display movement amount corresponding to the vector coordinates so that the vector direction and the size when viewed through the coordinate detection plane from the side match, the operator can easily obtain a desired movement by intuitive input. A display image can be obtained. Further, after inputting the coordinates of the start point of the input trajectory, each time the coordinate detecting means outputs the position coordinates of the input trajectory at fixed time intervals, the position coordinates are set as the end point position coordinates, and a predetermined display image is displayed by the display movement amount. By moving the display only by moving the image, the operator can check the display image that changes in accordance with the input trajectory being input at regular time intervals. Thereby, more accurate trajectory input can be performed, and a vector can be corrected while confirming a display image that changes in accordance with the input trajectory being input at regular time intervals. A display image can be obtained.

According to the information processing apparatus of the twelfth aspect, in addition to the effect of the information processing apparatus of the eleventh aspect, the same effect as that of the information processing apparatus of the third aspect can be obtained. . According to the information processing apparatus of the thirteenth aspect, in addition to the same effect as the information processing apparatus of the eleventh aspect, the same effect as that of the information processing apparatus of the fourth aspect can be obtained.
