Abstract

PROBLEM TO BE SOLVED: To provide a portable information terminal device or the like improved in portability, operability and visibility at the time of reading information. SOLUTION: A moving amount detecting part 16 detects the moving amount of an operation display unit at regular time intervals by moving the operation table display unit in a virtual space by a user.

Therefore, for the horizontally written text information, the entire information is displayed by wrapping one line into a plurality of lines, scrolling the screen horizontally, or tilting the device body horizontally. I was For this reason, it is difficult to construct a display screen that is easy to see because line breaks are forced at places that are not intended by the creator such as the Web, and when scrolling, the screen must be frequently scrolled in both vertical and horizontal directions. However, when the apparatus body is used by tilting the apparatus sideways, an operation surface such as an input is sacrificed.

[0006] Further, even in a notebook type or handheld type portable information device, it has not yet been possible to achieve both lightness and size in terms of portability and operability for improving visibility. With such a gender, it has not yet reached a level where anyone can easily carry and use it without feeling uncomfortable and can easily operate information like a mobile phone.

Next, the operation will be described. FIG. 6 is a flowchart illustrating a screen movement display process of portable information terminal device 1 according to the present embodiment.

In FIG. 6, first, the CPU 11 calculates the amount of movement in each direction of the X-axis and the Y-axis detected by the movement amount detector 16 at every fixed time based on the time data input from the clock unit 15. It is read and assigned to a variable dx (dy) representing the movement amount of the weight 16d (step S1).

Next, the CPU 11 calculates the moving acceleration ax (ay) from the variable dx (dy) in step S1, the spring constant k and the mass m of the weight 16d by the following equation (1) (step S2), and moves the apparatus. It is stored in the acceleration information memory 14f. dx · k = ax · m (1) However, the same applies to the Y-axis direction.

Further, the CPU 11 sets the movement acceleration ax ′ stored in the apparatus movement acceleration information memory 14f in the previous processing.
The moving speed vx (vy) is calculated by the following equation (2) in which the average value of (ay ′) and the currently calculated moving acceleration ax (ay) is multiplied by the elapsed time dt from the previous processing (step S3). Is stored in the apparatus moving speed information memory 14e.
This corresponds to a time integration of the acceleration. vx = (ax ′ + ax) / 2 · dt (2)

Further, the CPU 11 calculates the moving speed vx (vy) calculated in step S3 and the moving speed vx '(vy') stored in the apparatus moving speed information memory 14e in the previous processing.
The moving distance Lx (Ly) is calculated by the following equation (3), which multiplies the average value of the above by the elapsed time dt from the previous processing (step S4). This also corresponds to the process of calculating the moving distance to the virtual space by time-integrating the speed as in step S3. Lx = (vx ′ + vx) / 2 · dt (3)

Next, the CPU 11 calculates the moving distance Lx (Ly) calculated in step S4 as the current position V in the virtual space.
x (Vy) to update the position in the new virtual space (step S5), and to store the position information memory 14d in the virtual space.
To memorize. Further, new coordinates mx1 to mx2 (my1 to my2) (see FIG. 7) of the display area on the display buffer memory 14a corresponding to the current position in the virtual space are calculated by equations (4) and (5). (Step S6), and stores it in the display area information memory 14b. mx1 = Vx · Sx / 2 (4) mx2 = Vx · Sx / 2 (5) where Sx (Sy) shown in FIG. 7 is the length of the display area X direction (Y direction) of the liquid crystal display panel 6. Mx1 and m
x2 (my1 and my2) is the X coordinate of the upper left and upper right ends of the display area (Y coordinate of the upper right and lower right ends).

Then, before moving the display area to the position calculated in step S6 and stored in the display area information memory 14b, the CPU 11 determines whether or not new information is added around the current position in the virtual space. Confirm (Step S
7). If new information has been added in step S7, the CPU 11 determines whether the added bit image information has not been expanded based on the conversion data stored in the display data conversion information 14i. The information in the virtual space area is converted into two-dimensional planar bit image information, expanded to a corresponding position on the display buffer memory 14a, and stored in the display buffer memory 14a (step S8).

Next, the CPU 11 determines whether new information has been added in step S7, or after completing the operation in step S8, from the currently displayed position on the display buffer memory 14a to the display area information memory. 1
The display area of the liquid crystal display panel 6 is smoothly scrolled to the coordinates stored in 4b (step S9), and this processing ends.

As described above, the movement amount detection unit 16 detects the movement amount of the operation display unit 4 at regular intervals by the user moving the operation display unit 4 in the virtual space. Next, the CPU 11 calculates an acceleration from the detected movement amount, integrates the detected acceleration in a predetermined time region to calculate a movement speed, and similarly calculates
The moving distance in the virtual space is calculated by integrating the derived moving speed with time. Further, the CPU 11 adds the calculated moving distance to the current coordinates of the liquid crystal display panel 6 in the virtual space area, and converts the updated coordinates in the virtual space into coordinates on the display buffer memory 14a. The display area of the liquid crystal display panel 6 is smoothly moved to the updated coordinates.

Therefore, unlike the conventional display screen scrolling, the displayed contents are fixed, the display frame can be moved and browsed, and a flicker-free display is realized.

Also, by using the effect of utilizing the sense of distance of the user, once the displayed information is stored in the user's head together with the position, the device is moved to the position where the information is located when necessary. You can browse the desired information with just a click. This method of operation allows you to check information visually,
It enables more intuitive and comfortable information browsing faster than searching with a keyboard or the like.
