  In order to reduce the size of a portable information processing apparatus, it is necessary to reduce the number of input keys, and a configuration in which a so-called touch panel is provided instead of a fixed input key is known. By arranging the touch panel on the display device, the user can perform an input operation while confirming the content, and can freely change the input content and the operation position.

Patent Document 2 describes a technology for detecting vibration (blur) of an information processing apparatus and correcting an error in input information in an information processing apparatus having a handwritten character input function.

  The touch panel becomes smaller as the body becomes smaller. In order to obtain a sufficient input resolution, it is necessary to detect the touch position or touch amount of the touch panel more finely. However, when the area of the touch panel is reduced, it is difficult for the user to perform a fine touch operation within the small area.

  For example, there are cases where it is desired to adjust the volume, brightness, or the like by a touch operation. Although it is conceivable to input such an analog value by a touch time, it is actually difficult to input a user's desired value. Therefore, it is usually realized by a slide operation. However, when the area of the touch panel is reduced, it is difficult for the user to perform such a slide operation to meet a desired value in a small area, and it is necessary to increase the detection accuracy of the detection means. The latter causes an increase in cost.

In accordance with the correction control amount, characterized in that to realize a control function to control the body.

  The above-described control program is recorded on the recording medium according to the present invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic block diagram of an information browsing apparatus as an embodiment of an information processing apparatus according to the present invention.

  The information browsing apparatus 10 includes acceleration sensors 12X, 12Y, and 12Z. The acceleration sensors 12X, 12Y, and 12Z detect accelerations in the X-axis, Y-axis, and Z-axis directions of the information browsing apparatus main body, respectively. The acceleration detection circuit 14 calculates the movement direction and acceleration of the information browsing apparatus main body from the acceleration detected by the acceleration sensors 12X, 12Y, and 12Z, and supplies the calculation result to the system control circuit 16. The acceleration sensors 12X, 12Y, 12Z and the acceleration detection circuit 14 function as a movement detection unit that detects a spatial movement amount and a movement direction of the main body of the information browsing apparatus 10. In the present embodiment, the X axis and the Y axis are axes parallel to the panel surface of the touch panel 20, and the Z axis is an axis orthogonal to the panel surface of the touch panel.

  A capacitive touch panel 20 is arranged on the screen of the display device 18 for displaying characters and images. The input detection circuit 22 detects the input position (touch position) of the touch panel 20, the movement amount and movement direction of the input position, and supplies the detection result to the system control circuit 16. The movement amount and movement direction of the input position are the movement amount and movement direction of an operation (referred to as a slide operation) for moving a finger or the like touching the touch panel 20 on the touch panel 20 while touching the touch panel 20. The amount of movement and the direction of movement of the input position can be acquired from the X-axis direction component and the Y-axis direction component. The movement amount of the slide operation is an example of the input amount to the touch panel 20, and the movement direction of the slide operation is an example of the input direction to the touch panel 20.

  The present embodiment further includes a wireless communication interface 24. The wireless communication control circuit 26 controls communication between the wireless communication interface 24 and an external wireless communication device. The wireless communication control circuit 26 is connected to the data bus 28, and the system control circuit 16 is also connected to the data bus 28. The system control circuit 16 via the wireless communication control circuit 26 and a wireless communication interface 24 can receive image data and character data such as still and moving from the outside. The received data is stored in the storage device 30 via the data bus 28. The storage device 30 is composed of, for example, a semiconductor nonvolatile memory.

  The signal processing circuit 32 generates an image signal for display from the character image data stored in the storage device 30 in accordance with the instruction signal from the system control circuit 16. The signal processing circuit 32 also has a function of expanding compressed image data. The display control circuit 34 displays an image on the display device 18 in accordance with the image signal from the signal processing circuit 32. The display device 18 is composed of, for example, a liquid crystal display device, and the display control circuit 34 is composed of a drive circuit that drives the liquid crystal display device. The signal processing circuit 32 also has a function of decoding and converting the encoded audio signal into an analog signal. However, the signal processing circuit 32 is not related to the characteristic operation of the present embodiment, and thus the description thereof is omitted.

  With reference to FIG. 2, the characteristic operation of the present embodiment will be described. In this embodiment, the frame feed amount for moving image playback is controlled by a combination of the slide operation on the touch panel 20 and the horizontal movement of the main body. FIG. 2A1 shows a state where the user slides his / her finger from left to right on the touch panel 20. FIG. 2A2 shows an example of change in the display image in which the frame advance amount is 1 second with respect to the operation shown in FIG. FIG. 2 (B1) shows how the user slides his / her finger from left to right on the touch panel 20 and moves the main body in the left direction. FIG. 2B2 shows an example of a change in the display image in which the frame advance amount is 5 seconds in response to the operation shown in FIG.

  When the finger is slowly and carefully slid on the touch panel 20, the main body does not shake, but when the user hurries up, the main body often moves in the reverse direction as shown in FIG. 2 (B1). When the main body moves in the direction opposite to the sliding direction on the touch panel, it can be determined that the user desires a larger change. Therefore, in this embodiment, in the case of such an operation mode, image reproduction is controlled to a larger frame advance.

  FIG. 3 shows a flowchart of the reproduction control of this embodiment. The system control circuit 16 obtains an operation input (I) (movement amount and input direction of the input position) by the user to the touch panel 20 from the output of the input detection circuit 22 (S1). The system control circuit 16 calculates a frame feed amount X as a control amount from the X-axis component of the movement amount of the input position to the touch panel 20, and at the same time, the frame feed direction (forward direction, The reverse direction is determined (S2). In other words, the system control circuit 16 functions as a control amount generation unit in the scope of claims and serves as a unit that realizes a control amount generation function in the case of a program operation.

  Separately, the system control circuit 16 acquires acceleration data output from the acceleration detection circuit 14 (S3). The acceleration data is vector data composed of accelerations of the X, Y, and Z axis components. Of the acquired acceleration data, the system control circuit 16 acquires an acceleration component A that is coaxial with the component for which the control amount is calculated, in the direction of movement of the input position to the touch panel 20 (S4).

  The system control circuit 16 checks whether the movement direction of the component for which the control amount is calculated and the direction of the acceleration component A are the same among the movement directions of the input position to the touch panel (S5). If not in the same direction (S5), the system control circuit 16 compares the acceleration component A with a predetermined threshold A0 (S6). If the acceleration component A is greater than or equal to A0 (S6), the acceleration A is compared with a threshold value A1 that is greater than the threshold A0 (S7). That is, it is examined which of the three cases the acceleration component A is smaller than A0, A0 or more and A1 or less, and A1 is exceeded (S6, S7).

  Among the movement directions of the input position to the touch panel 20, when the movement direction of the component for which the control amount is calculated and the direction of the acceleration component A are the same (S5), or when the acceleration component A is smaller than A0 (S6), The feed correction coefficient α is set to 0 (S10). When the acceleration component A is not less than A0 and not more than A1 (S7), the frame advance correction coefficient α is set to 1 (S8). When the acceleration component A exceeds A1 (S7), the frame advance correction coefficient α is set to 4 (S9).

The system control circuit 16 corrects the frame feed amount X as the correction control amount by using the frame feed correction coefficient α determined in this way (S11). That is, the corrected frame feed amount Xm is set to
Xm = (1 + α) × X (1)
And Then, the system control circuit 16 instructs the signal processing circuit 32 to perform frame advance reproduction according to the obtained corrected frame advance amount Xm (S12). A control program that operates on the system control circuit 16 realizes a correction function that corrects the frame feed control amount according to information on the movement amount and movement direction of the main body, and controls the main body according to the correction control amount obtained by the correction. To realize the control function.

  FIG. 4 shows the value of the corrected frame feed amount Xm when the frame feed amount X is 30 frames, that is, 1 second. When there is no movement of the apparatus main body, since the frame advance correction amount α = 0, the corrected frame advance amount remains 30 frames. When the main body moves in a direction opposite to the operation direction of the touch panel 20 by a predetermined amount or more, the frame advance correction amount α = 4, and the corrected frame advance amount is 150 frames, that is, 5 seconds.

  In the present embodiment, the control amount by operating the touch panel 20 is increased when the movement direction of the component for which the control amount is calculated and the movement direction of the main body are the reverse of the movement directions of the input position to the touch panel 20. To correct. That is, in the same direction as the panel surface of the touch panel 20, the control amount is increased when the acceleration direction of the main body is substantially opposite to the moving direction of the input position to the touch panel 20. On the other hand, another correction may be combined. For example, as the acceleration in the Z-axis direction of the main body increases, the device is controlled in accordance with the momentum during input to the touch panel 20 by performing a correction that increases the control amount regardless of the moving direction of the input position to the touch panel 20. To do.

  The touch panel 20 can be tapped in addition to the slide operation. The tap operation is an operation of touching one point on the touch panel 20 and releasing a finger without substantially moving, and is an operation generally used for pressing a button icon or the like. By this tap operation, a force is applied in the Z-axis direction of the main body, that is, the direction orthogonal to the panel surface of the touch panel 20. Therefore, during this tap operation, correction may be performed to increase the control amount by the tap operation as the acceleration in the Z-axis direction of the main body increases. By doing in this way, control amount control according to the momentum of operation when a user performs a tap operation or insertion of force can be performed.

  According to the present invention, by correcting the input amount to the input means with the correction amount corresponding to the movement amount of the apparatus main body, it is possible to compensate for the shortage of input amount and resolution in the small input means.

  In addition, the amount of correction changes depending on the momentum or force of the operation when the user inputs to the input means, so if the user performs an input operation in a hurry or if force is applied, the operation is performed slowly and carefully. Different operation results can be obtained. That is, it is possible to reflect the behavior of the user with respect to the device in the device control.

  Although the embodiment has been described in which the acceleration sensor is used as the movement detection means for detecting the spatial movement amount and the movement direction of the main body, it may be a speed sensor or a means for detecting the displacement of the position.

  It is obvious that various controls of the system control circuit 16 may be executed by a single piece of hardware or by a plurality of pieces of hardware. The operation shown in FIG. 3 can also be implemented as a control program that operates on the system control circuit 16.

  The present invention is not limited to the above-described embodiments, and various forms within the scope of the present invention are also included in the present invention.

  Although the embodiment applied to the document browsing apparatus has been described, the present invention is applicable to various information processing apparatuses having a touch panel, such as a personal computer, a PDA, a mobile phone terminal, or a portable document image viewer.

  Part or all of the functions of the present invention can be realized by a software program that functions on the information processing apparatus. The software program can be stored in a computer-readable recording medium and installed in the information processing apparatus according to the present invention.
