Abstract

PROBLEM TO BE SOLVED: To provide a portable information processor which can magnify and display the coordinate data inputted by a finger in order to surely perform its operation. SOLUTION: An input display operation is performed to a display means 7 via a touch panel 1. When a touch pen 2 or a finger 3 touches the panel 1, a pressure-sensitive element of the panel 1 outputs a signal to make a detection means 4 detect the touch area. Then a data processing means 5 decides whether the pen 2 or the finger 3 touched the panel 1 based on the touch area detected by the means 4 and also on a parameter 51 shown in an area that is previously set. When an input operation performed by the pen 2 is decided, the input coordinate data are generated from the touched coordinate data. If an input operation performed by the finger 3 is decided, a control means 6 functions to show the input coordinate data in such a size that can be inputted by the finger 3 and to display the coordinate data on the means 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing device, and more particularly to a portable information processing device having a touch panel.

[0002]

2. Description of the Related Art A conventional (not shown) portable information processing device uses a touch panel that also serves as a display as an input means, a calculator,
It has various functions such as a scheduler, address book, dictionary, and fax transmission, and is characterized by being easily used anywhere. This device is often small, and complex information can be immediately input to the touch panel with a dedicated touch pen. can do.

[0003]

In this conventional portable information processing device, since the touch panel is small, the coordinate data input and processed only by the touch pen is extremely displayed despite the fact that the human finger reacts. There is a problem in that even a small function such as a calculator needs to be operated with a touch pen.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable information processing device equipped with a touch panel for displaying input coordinate data by a finger in an enlarged manner for reliable operation.

[0005]

In order to solve the above-mentioned problems, a portable information processing device of the present invention is a touch panel in which pressure-sensitive elements are arranged in the XY directions, and a pressure-sensitive in the XY directions when the touch panel is touched. Display means for displaying coordinate data by a signal output from the element, detection means for detecting a touch area by a signal output from the pressure-sensitive element in the XY directions when the touch panel is touched, and detection means for detecting the touch area. Based on the touch area and a parameter expressed by a preset area, it is determined whether the touch data is touched by a touch pen or a finger, and the data processing means processes the coordinate data, and it is determined that the data processing means touches with a finger. And a control means for controlling the coordinate data to be enlarged and displayed on the display means only when processed.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a portable information processing device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a portable information processing device according to an embodiment of the present invention.

FIG. 2 is a flowchart of the portable information processing device according to one embodiment of the present invention.

FIG. 3 is an explanatory diagram of input coordinate data of the portable information processing device according to one embodiment of the present invention.

As shown in FIG. 1, a portable information processing apparatus according to an embodiment of the present invention has a touch panel 1 in which pressure-sensitive elements are arranged in the XY directions, and a pressure-sensitive element in the XY directions when the touch panel 1 is touched. The display means 7 for displaying coordinate data by a signal output from the touch panel 1, the detection means 4 for detecting the touch area by the signal output from the pressure sensitive element in the XY directions when the touch panel 1 is touched, and the detection means 4. The touch pen 2 or the finger 3 is used based on the touched area and the parameter 51 represented by the preset area.
The data processing means 5 for processing the coordinate data by determining whether or not the touch has been made, and the display means 7 for displaying the coordinate data only when the data processing means 5 determines that the finger 3 has touched and processed.
And a control means 6 for controlling the enlarged display.

Next, the operation of the portable information processing device according to the embodiment of the present invention will be described with reference to the drawings.

In the operation of the portable information processing apparatus according to the embodiment of the present invention, as shown in FIGS. 1 and 2, first, an input display is performed from the touch panel 1 to the display means 7 (step 2
01) For example, as shown in FIG. 3, when displaying a ten-key portion of a calculator or the like, one key portion is displayed in a size that can be input by the touch pen 2, and even if the tip of the touch pen 2 is a small display, Input is possible and more complex input display is possible.

Thereafter, the touch panel 1 enters a loop waiting for input (step 202), and the touch pen 2 or finger 3
When the touch panel 1 is touched, the pressure-sensitive element of the touch panel 1 outputs a signal and the touch area is detected by the detection means 4. The touch area detected by the detection means 4 and the preset area are displayed. The data processing means 5 determines whether the touch pen 2 or the finger 3 is touched based on the parameter 51 (step 203).

The signal output from the pressure sensitive element of the touch panel 1 is at "H" level (1), and the other signals are at "L" level (0).
Then, if the touch area represented by the "H" level signal is smaller than the reference value SH of the parameter 51, the touch pen 2 input processing (step 208) is performed, and if it is larger, the input processing by the finger 3 is performed (step 204). When the touch area when touching with 2 is S1 and the touch area when touching with the finger 3 is S2, the following equation holds: S1 <SH <S2 The data processing means 5 discriminates according to this equation, and the touch pen 2 When it is determined that the input is input, as shown in FIG. 3A, the input coordinate data is processed from the touched ten-key pad (step 209).

On the other hand, when it is determined that the input is made with the finger 3, the operation shown in FIG.
(B), the control means 6 controls and displays on the display means 7 such that one key portion of the ten-key pad for enlarging and displaying the input coordinate data can be displayed in a size that can be input with the finger 3. 205), waits for the next input (step 206), and processes input coordinate data from the touched ten-key pad (step 207).

[0016]

As described above, according to the portable information processing device of the present invention, the touch area on the touched touch panel is calculated, and it is determined whether the touch area is touched with the touch pen or the finger. By enlarging and displaying the input coordinate data only when the input is made with the finger, there is an effect that the input of the coordinate data by the finger can be surely operated.
