[0019]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. <First Example> [First Example] FIG. 1 is a six-view drawing of an information processing apparatus according to the present embodiment. A liquid crystal display panel 2 is provided on the front surface of a main body 6 of the information processing apparatus 1, a push-down button 3 and a pen holder 4 are provided on the upper surface, and an IC card insertion slot 5 is provided on the lower surface. Further, inside the main body 6, a CPU (central processing unit) and a detection sensor for detecting an amount related to the movement of the main body 6 are incorporated. By replacing the IC card through the IC card insertion slot 5, the CP
The U software can be switched to a word processor, a spreadsheet, or the like.

As input means for the information processing apparatus 1, usually, a pen (not shown) housed in a pen holder 4 is used to indicate coordinates on the liquid crystal display panel 2, and an input is made by pressing a button 3. In addition to the input, the body 6
There is input by moving. The input by moving the main body 6 is the following input method. That is,
When the main body 6 is moved vertically and horizontally, the amount of vertical movement and the amount of horizontal movement of the main body 6 are detected by the detection sensor provided inside. Then, the content such as a sentence displayed on the liquid crystal display panel 2 is scrolled in the movement direction detected by the number of pixels corresponding to the detected movement amount.

FIG. 2 shows an operation example of scrolling the display contents by moving the main body 6. In FIG. 2A, a tulip flower portion is displayed on the liquid crystal display panel 2 of the information processing apparatus 1 held by the operator in his left hand (most of tulip leaves are outside the area of the liquid crystal display panel 2). I can see only a part of it because I am in When displaying the leaf portion of the tulip on the liquid crystal display panel 2 in this state, the main body 6 is moved in the direction of the arrow (a) (that is, from the original position of the main body 6 to the lower right direction). Then, as shown in FIG. 2B, the portion of the tulip leaf, which is not visible at the lower right of the liquid crystal display panel 2 in FIG. 2A, is scrolled on the liquid crystal display panel 2. It will appear within 2.

FIG. 3 is a block diagram of essential parts relating to a scroll function by moving the main body 6 in the information processing apparatus 1. The acceleration sensor 11 as the detection sensor detects the acceleration of the main body 6 as the main body 6 moves. The motion analysis unit 12 analyzes the motion of the main body 6 based on the detection result from the acceleration sensor 11 to obtain the moving (rotating) direction and the moving (rotating) amount. The scroll processing unit 13 serving as the information processing unit and the process instruction unit reads the area of the image information for one frame read from the image information storage unit 14 and sent to the display unit 15 by the number of pixels corresponding to the movement amount of the main body 6. Only the data is read out by shifting in the direction corresponding to the moving direction of the main body 6. The display unit 15 has the liquid crystal display panel 2 and displays an image on the liquid crystal display panel 2 based on the image information sent from the scroll processing unit 13. The motion analysis unit 12 and the scroll processing unit 13 are specifically configured by the CPU.

When the hand holding the main body 6 of the information processing apparatus 1 is moved to move the main body 6 in this manner, the liquid crystal display panel 2 of the display unit 15 displays an amount corresponding to the moving amount in the moving direction. The displayed contents are scrolled.

The acceleration sensor 11 for detecting the acceleration of the main body 6 detects the vertical acceleration and the horizontal acceleration by two different acceleration sensors. Figure 4
Shows an arrangement example of the above two acceleration sensors. The acceleration sensor 7 detects the acceleration in the right and left directions, which is positive in the right direction (arrow (b) direction), of the acceleration of the main body 6. On the other hand, the acceleration sensor 8 detects vertical acceleration with the upward direction (arrow (C) direction) being positive. The time sum of the accelerations thus detected is the speed, and the time sum of the speeds corresponds to the movement amount.

FIG. 5 shows an acceleration-time detected by the acceleration sensors 7 and 8 when the main body 6 in which the acceleration sensors 7 and 8 are arranged as shown in FIG. 4 is moved in the direction shown in FIG. A typical example of a curve is shown. FIG. 5 (a) shows the acceleration sensor 7
5 shows an acceleration-time curve in the right direction according to FIG. 5, and FIG. 5B shows an acceleration-time curve in the upward direction due to the acceleration sensor 8.

FIG. 6 shows the time sum (that is, speed) of the detection values (see FIG. 5) of the acceleration sensors 7 and 8 calculated by the motion analysis unit 12. However, the solid line is the speed in the right direction based on the detection value of the acceleration sensor 7, and the dashed-dotted line is the speed in the upward direction based on the detection value of the acceleration sensor 8. Both speeds are shown on the same time axis. That is, the dot on the solid line represents the amount of scrolling of the display content to the right per unit time at that time, and the point on the alternate long and short dash line represents the amount of scrolling upward of the display content per unit time at that time. There is.

FIG. 7 is a time sum (that is, a moving amount) of each velocity value (see FIG. 6) calculated by the motion analysis unit 12.
Indicates. However, the solid line is the amount of movement in the right direction based on the detection value of the acceleration sensor 7, and the dashed-dotted line is the amount of movement in the upward direction based on the detection value of the acceleration sensor 8. That is, the point on the solid line is the amount of movement of the display content to the right from the reference value at that time, and the point on the alternate long and short dash line is the amount of movement of the display content from the reference value to the upper side at that time.

Therefore, the scroll processing section 13 causes the display contents of the liquid crystal display panel 2 to move in the moving direction shown in FIG.
That is, the number of pixels corresponding to the movement amount shown in FIG. 7 is scrolled in the lower right direction.

In the information processing apparatus 1 as described above,
Every time the main body 6 is moved, the display content on the liquid crystal display panel 2 is scrolled. Therefore, it is necessary to be careful not to move the main body 6 when viewing the displayed contents. Further, even if the main body 6 is moved to scroll the display contents to display the desired contents, if the position of the main body 6 is returned to its original position, the display contents changed at all will return to the original inconvenience.

Therefore, by pressing the button 3 as the information processing stop portion provided on the upper surface of the main body 6 as described above, the display content scroll function is "on / off" controlled. FIG. 8 shows an operation example in which the motion analysis unit 12 and the scroll processing unit 13 operate only while the button 3 is pressed to perform the scroll operation. Figure 8 (a)
Is the initial state. In this state, the button 3 is pressed as shown in FIG. 8 (b). Then, while pushing the button 3 and moving the main body 6 to the right as shown by the arrow (d),
The display contents are scrolled to the right as shown in (c).
Next, as shown in FIG. 8 (d), when the user releases the button 3 and moves the main body 6 to the left as indicated by the arrow (e), the displayed contents are changed to those shown in FIG. 8 (e). It remains (d).

By doing so, the liquid crystal display panel 2
Main body 6 for scrolling the contents displayed on
Can be distinguished from the simple movement, and the unnecessary scrolling of the display contents as described above can be prevented.

As described above, in the present embodiment, the acceleration sensor 7 for detecting the acceleration of the main body 6 in the left-right direction in which the right direction is positive and the upward direction in the main body 6 of the information processing apparatus 1 are positive. An acceleration sensor 8 that detects vertical acceleration is provided. Then, the motion analysis unit 12 calculates the time sum of the acceleration in the right direction detected by the acceleration sensor 7, and further calculates the time sum to obtain the lateral movement amount of the main body 6. Similarly, the amount of vertical movement of the main body 6 is obtained from the upward acceleration of the acceleration sensor 8.

Then, the scroll processing unit 13 scrolls the display contents of the liquid crystal display panel 2 in the horizontal direction by the number of pixels corresponding to the amount of horizontal movement of the main body 6 obtained by the motion analysis unit 12 in this way. To do. On the other hand, the scroll processing unit 1 changes the display content of the liquid crystal display panel 2 by the number of pixels according to the vertical movement amount of the main body 6.
Scroll up and down with 3.

Therefore, when it is desired to scroll the display content displayed on the liquid crystal display panel 2, the display content can be scrolled by a simple operation of moving the main body 6 in the desired scroll direction. That is, according to the present embodiment, it is possible to easily carry out an instruction to change the display content with the same hand while holding the information processing device 1 in the hand, and to easily realize a portable information processing device.

In the case of the above embodiment, the liquid crystal display panel 2
When scrolling the display contents above, it is necessary to always press the button 3. Therefore, when it is necessary to continuously change the display content, the button 3 must be kept pressed, which causes a slight difficulty in operability. Therefore, as a modified example, an example in which the mode is switched from the normal mode to the display content change mode by pressing a button will be described below.

FIG. 9 shows an operation example of the information processing apparatus which is switched to the display content change mode by pressing the button. FIG. 9A shows the initial state. In this state, as shown in FIG. 9B, when the button 9 is pressed, the mode is switched to the display content change mode. As a result, as shown in FIGS. 9 (c) and 9 (d), the button 9 is released and the arrow (f) is released.
Even if the main body 6 is moved to the right like this, the display contents are scrolled to the right. Next, as shown in FIG. 9E, when the button 9 is pressed again, the mode is returned to the normal mode.
As a result, as shown in FIG. 9 (f) and FIG. 9 (g), even if the user removes his / her finger from the button 9 and moves the main body 6 to the left as shown by the arrow (g), the displayed content is as shown in FIG. 9 (f). ) Remains.

[Second Embodiment] In the first embodiment, the vertical and horizontal movements of the main body 6 are associated with the vertical and horizontal scrolling of the contents displayed on the liquid crystal display panel 2.
However, the present invention is not limited to this. In this embodiment, the movement of the main body 6 is associated with the enlargement / reduction of the display content.

FIG. 10 shows an operation example of the information processing apparatus in this embodiment. Note that the external appearance of the information processing apparatus in each of the embodiments described below is the same as that in FIGS. 1 and 2, so that each embodiment described below will be described using the numbers shown in FIGS. 1 and 2. In this embodiment, when the main body 6 is moved forward (that is, the liquid crystal display panel 2 side), the display content of the liquid crystal display panel 2 is enlarged by a magnification corresponding to the amount of movement. On the other hand, when the main body 6 is moved backward, the display content is reduced by the magnification according to the movement amount. This can be realized by using the acceleration sensor 11 in FIG. 3 as an acceleration sensor that detects an acceleration in the front-rear direction in which the front direction of the main body 6 is positive, and replacing the scroll processing unit 13 with an enlargement / reduction processing unit.

Further, as a modification of this embodiment, there is the following example. That is, when an IC card for a word processor is inserted into the IC card insertion slot 5 and the information processing device functions as a word processor, the document indicating the forward movement of the main body 6 on the liquid crystal display panel 2 is displayed. On the other hand, the rearward movement of the main body 6 is associated with the page return while the page is forwarded.

<Second Example> In each of the above embodiments, the movement of the main body 6 in the front / rear / left / right / vertical directions is associated with a change in the display content on the liquid crystal display panel 2. This is
This means that the rotation of the main body 6 can be associated with the change in the display content without any trouble.

[Third Embodiment] FIG. 11 is a block diagram of an essential part of an information processing apparatus in which the rotation of the main body 6 is associated with a change in display content (rotational movement of a viewpoint). The angular acceleration sensor 21 as the detection sensor detects the angular acceleration of the main body 6 due to the rotation of the main body 6 around the vertical axis. Motion analysis unit 12
Calculates the rotation direction and rotation angle of the main body 6 based on the detection result from the angular acceleration sensor 21. Then, the viewpoint rotation processing unit 22 as the information processing unit and the processing instruction unit stores image information for one frame obtained by rotating and moving the viewpoint in the rotation direction of the main body 6 by an angle corresponding to the rotation angle of the main body 6. It is read from the unit 14 and sent to the display unit 15. At that time, the motion analysis unit 12 calculates the time sum of the angular accelerations detected by the angular acceleration sensor 21 to obtain the angular velocity, and further calculates the time sum of the angular velocity to obtain the rotation angle.

In this way, when the hand holding the main body 6 of the information processing apparatus 1 is moved to rotate the main body 6 around the vertical axis, the liquid crystal of the display unit 15 is rotated in the direction of rotation by an angle corresponding to the rotation angle. The operator's viewpoint with respect to the object displayed on the display panel 2 is rotated.

FIG. 12 shows an operation example of the information processing apparatus in this embodiment. As shown in FIG. 12B, when the main body 6 is rotated around the vertical axis, the operator's viewpoint of the automobile displayed on the liquid crystal display panel 2 is rotationally moved. Therefore, the image of the front of the vehicle displayed on the liquid crystal display panel 2 in FIG. 12 (a) is changed to the image of the side of the vehicle by rotating the main body 6 by 90 degrees as shown in FIG. 12 (b). Of.

In FIG. 11, an angular acceleration sensor 21 is used as the detection sensor. However, as described below, the rotation angle of the main body 6 can be obtained by using the acceleration sensor. That is, as shown in FIG. 13, the acceleration sensors 23 and 24 are attached at target positions with respect to the vertical axis of the main body 6. The acceleration sensor 23 makes the acceleration in the arrow (h) direction positive, while the acceleration sensor 2
4 has a positive acceleration in the direction of arrow (i). FIG. 14 is a typical example of the acceleration-time curve detected by the acceleration sensors 23 and 24 when the main body 6 shown in FIG. 13 is rotated around the vertical axis as shown in FIG. 12 (b). Then, a curve as shown in FIG. 15 is obtained by subtracting the detection value by the acceleration sensor 24 shown in FIG. 14B from the detection value by the acceleration sensor 23 shown in FIG. 14A.

By regarding the curve shown in FIG. 15 as a value proportional to the angular acceleration of the main body 6 having the positive rotation direction shown in FIG. 12 (b), the time sum of the curve shown in FIG. 15 is calculated to obtain the angular velocity. Further, the rotation angle of the main body 6 can be obtained by calculating the time sum of the accelerations. Therefore, it is possible to change the amount of change and the speed of change of the viewpoint with respect to the video object displayed on the liquid crystal display panel 2 using the angular velocity and the rotation angle thus obtained.

In the above embodiment, the acceleration sensor 24
Uses the acceleration in the arrow (i) direction as positive and detects the acceleration in the front-back direction. However, the acceleration sensor 24 detects the acceleration in the front-rear direction with the acceleration in the arrow (i) direction as a negative value, and adds the detection value of the acceleration sensor 24 to the detection value of the acceleration sensor 23. A value proportional to the angular acceleration as shown may be obtained.

In this embodiment, the rotation angle of the main body 6 around the vertical axis is associated with the amount of change of the viewpoint with respect to the image object. If the rotation angle can be measured, the viewpoint of the video object can be changed three-dimensionally. This represents the information of the position of each point on the object displayed on the liquid crystal display panel 2 by three-dimensional data, and based on this three-dimensional data, the rotation angle around the vertical axis and the horizontal axis in the main body 6 are shown. This can be easily realized by obtaining the image information of the object viewed from the viewpoint according to the rotation angle around.

<Third Example> In each of the above-described embodiments, the input by the movement of the main body 6 is used as the input of the instruction to change the display content of the liquid crystal display panel 2. However,
As described below, it is possible to use the input by moving the main body 6 as an instruction input during information processing.

In the embodiment shown in FIG. 16, when applied to a word processor, a graphic tool, etc., the moving direction and the moving amount of the cursor position on the liquid crystal display panel 2 are adjusted according to the moving direction and the moving amount of the main body 6. It is an example which controls. In FIG. 16A, the liquid crystal display panel 2
The cursor 30 is located at the position of the stem of the tulip displayed in. In this state, the main body 6 is moved to the lower right as shown by the arrow (nu). Then, as shown in FIG. 16B, the cursor 3 is moved according to the moving direction and the moving amount of the main body 6.
The 0 position moves to a position above the tulip flower.

FIG. 17 is a block diagram of essential parts of the information processing apparatus in which the moving direction and the moving amount of the main body 6 described above are associated with the moving direction and the moving amount of the cursor. In FIG. 17, the cursor drawing unit 31 as the information processing unit and the processing instruction unit has a number of pixels corresponding to the movement amount of the main body 6 in the direction opposite to the movement direction of the main body 6 obtained by the motion analysis unit 12. The cursor drawing position is moved.

In the case of the embodiment shown in FIG. 16, the moving direction of the main body 6 is associated with the moving direction of the display screen with respect to the position of the cursor 30 in the absolute space. However, the moving direction of the cursor 30 may be associated with the display screen on the liquid crystal display panel 2. However, in that case, the main body 6 must be moved in the direction opposite to the arrow (nu).

The embodiment shown in FIG. 18 is an embodiment in which the moving direction of the main body 6 is associated with a "yes / no" response when the processing is carried out interactively with the operator. That is, by vertically swinging the main body 6 as shown in FIG. 18A, the amount of vertical movement is detected, and the response is determined to be "yes". On the other hand, as shown in FIG. 18B, by swinging the main body 6 back and forth, the amount of movement in the front-back direction is detected, and the response is determined to be “no”.

FIG. 19 is a block diagram of an essential part of the information processing apparatus in which the moving direction of the main body 6 described above is associated with a "yes / no" response. In FIG. 19, the dialogue processing unit 35 as the information processing unit and the processing instruction unit displays a message on the display unit 15 to prompt the operator to respond. When the operator moves the main body 6 in response to this message, the acceleration sensor 11 and the motion analysis unit 12 detect the moving direction of the main body 6. Then, the dialogue processing unit 35 determines whether the response to the message is "yes" or "no" based on the detected moving direction of the main body 6 and executes the processing according to the response.

FIG. 20 is a flowchart of the dialogue processing subroutine executed by the dialogue processing unit 35 at that time. In response to the response message (step S1) displayed on the liquid crystal display panel 2, the operator swings the main body 6 in the vertical direction or the front-back direction. Then, the direction in which the main body 6 is shaken is detected based on the output signal from the acceleration sensor or the like (step S2, step S
Four). Then, processing according to the detected direction is performed.
(Step S3, Step S5).

In the embodiment shown in FIG. 18, the direction in which the main body 6 is shaken is associated with "yes / no", but as shown in FIG. 21, the number of times the main body 6 is shaken is "yes / no".
It may be associated with "/ no". In this case, one acceleration sensor can determine "yes / no".

FIG. 22 is a block diagram of an essential part of the information processing apparatus in which the moving direction of the main body 6 is associated with the instruction input during the kana-kanji conversion processing. In FIG. 22, a hiragana character is pen-input from an input unit 41 configured by a tablet integrally incorporated in the liquid crystal display panel 2 of the main body 6 and the pen. Then, the hiragana character input by the pen is recognized by the character recognition / conversion unit 42. Further, the recognition result is converted into Kana-Kanji. The recognition result thus obtained and a kanji candidate obtained by converting the recognition result into kana-kanji are stored in the storage unit 43.
Then, the recognition result is first selected by the candidate selecting section 44 which is the information processing section and the processing instructing section, transmitted to the display section 15, and displayed on the liquid crystal display panel 2.

If the recognition result displayed on the liquid crystal display panel 2 is correct, the operator shakes the main body 6 vertically. Then, the acceleration sensor 11 and the motion analysis unit 1
2 determines the moving direction of the main body 6 as described above. If the moving direction of the main body 6 obtained by the motion analysis unit 12 is the vertical direction, the candidate selection unit 44 stores the first data from the storage unit 43.
The code of the candidate kanji character of rank is read out and sent to the display unit 15 to be displayed on the liquid crystal display panel 2. Thus, each time the main body 6 is vertically swung, the next candidate Kanji candidate is read and displayed by the candidate selecting unit 44. On the other hand, if the moving direction of the main body 6 is forward or backward, the code of the previous candidate Kanji character is read and displayed on the liquid crystal display panel 2.

The information processing apparatus having the above configuration is operated as shown in FIG. That is, in FIG. 23 (a), the character "kan" is formed on the surface of the liquid crystal display panel 2 by the pen (not shown).
When you write, the character entered with this pen is recognized.
A state in which the recognition candidate “Kan” that has been recognized by the conversion unit 42 and has the first highest degree of similarity is displayed.

In this state, when the main body 6 is vertically shaken once,
As shown in FIG. 23 (b), the display content of the liquid crystal display panel 2 is changed to the first Chinese character candidate “Kan”. Thereafter, as shown in FIG. 23 (c), the next candidate Kanji is sequentially displayed each time the main body 6 is vertically swung. In addition, as shown in FIG.
When is swung in the front-back direction, the display content of the liquid crystal display panel 2 returns to the character of the previous candidate.
