FIG. 10 is a view showing the outer appearance of the electronic information device according to this embodiment. Now, in FIG. 10, it is assumed that the operation 1001 which is the main body of the electronic information device is momentarily shaken in the direction indicated by the arrow 1003. At this time, the vertical acceleration sensor 101 and the horizontal acceleration sensor 102 shown in FIG. 1 generate output waveforms as shown in FIGS. 3 and 4, respectively. Here, arrow 301 indicates the upward movement in FIG. 10, and arrow 401 also indicates the upward movement in FIG. Further, in both waveform diagrams, portions 303 and 403 are portions where the operator who holds the electronic information device 1001 of FIG. 10 has performed a sudden swing, and the fine irregular vibrations appearing after that time are A vibration that is not intended by the operator and that usually appears when the electronic information device is carried or held is detected.

The operation of this embodiment will be described in detail below with reference to the flow chart shown in FIG.

In FIG. 2, step S201 indicates that scrollable window display has started on the display screen of the electronic information device according to the present embodiment.

Next, in step S202, acceleration sensor output detection is performed, and output detection of both sensors 101 and 102 shown in FIG. 1 is started. At this time, in the electronic information device 1001 shown in FIG. 10, some acceleration detection is always performed by both the sensors except when it is in a completely stationary state. The output is detected in the direction of the acceleration detected in step S203, that is, the direction of the combined acceleration of the accelerations detected by the both sensors, and at the same time, in step S204, the acceleration in the combined direction of the two sensors is detected. Size detection is performed.

Next, in step S205, step S
The value of the amount of acceleration detected in 204 is compared with a threshold value prepared in advance. At this time, step S204
When the value of the magnitude of the acceleration detected in is smaller than the above-mentioned threshold value, the process returns to step S202 and the output of the acceleration sensor is detected again. Also, step S2
In 05, when the value of the magnitude of the acceleration detected in step S204 is larger than the above-mentioned threshold value, the process proceeds to step S206. The amount of acceleration detected at this time will be described with reference to FIGS.

Now, the operator applies a rapid acceleration to the electronic information device according to the present embodiment for the purpose of scrolling the screen, and as a result, the acceleration of the acceleration sensor as shown in FIGS. Suppose a detection is made. The waveforms detected by both sensors are combined as shown in the circular graph in FIG. Here, reference numeral 501 indicates a synthesized waveform, and in the waveform 501, the waveform concentrated in the center of the circular graph is compared with the threshold value in step S205 of FIG. 2 and is smaller than the threshold. The waveform is determined to be.

Here, the circle indicated by 502 is a circle showing a threshold value to be compared with the value of the magnitude of the synthesized acceleration, and in the case of the waveform 501, a part greatly exceeds the threshold value 502. It extends to the value of the magnitude of the acceleration indicated by the circle 503, and this portion of the waveform 501 corresponds to the sudden acceleration given by the operator.

In step S206, step S205
In, the direction of actual scrolling is determined at the maximum value point of the magnitude of the 501 waveform portions that exceed the threshold value. For example, with respect to the above-mentioned waveform portion, from the position of the maximum point projected on the X axis and the Y axis of the circular graph of FIG. Is detected. From this, a negative direction is determined for the X axis and a negative direction for the Y axis, which is the opposite direction to the detected acceleration, for the scrolling direction.

In step S207, the amount of scrolling movement, that is, the amount of scrolling movement, which is approximately proportional to the distance from the center of the maximum value point distinguished by the circles 502 and 503 in FIG. 5, is determined. Then, in step S208, steps S206 and 2
The scroll direction and the scroll movement amount determined by 07 are output to the scroll window to execute scrolling. Here, the description of the method of actually performing the scroll operation for the window is omitted here because it is not directly related to this embodiment. Therefore, as shown in FIG. 9, the graphic 9 is displayed on the scroll window 901.
When 04 is displayed, when the operator gives a rapid acceleration as indicated by arrow 902 to the electronic information device having the scroll window, the scroll window 901 performs scroll movement as indicated by arrow 903. As a result, the previously displayed graphic 904 is graphic 9
The result is movement to the position indicated by 05.

As described above, according to this embodiment, FIG.
When holding the portable electronic information device as shown in 0 with one hand and holding the portable electronic information device with the other hand by performing a rapid movement operation as indicated by arrow 1003, the other hand is held. There is an effect that the operation of moving the screen can be comfortably performed by using an extremely natural operation without using.
