Abstract

PURPOSE:To provide the input device capable of satisfactory designation like a dial by rotating a finger or the like on a coordinate input sensor by a user to designate a coordinate value and detecting this coordinate value by the coordinate input sensor to calculate the number of rotations and changing a set value. CONSTITUTION:The user vertically scrolls the picture by clockwise or counterclockwise rotation of his finger on an input part consisting or a coordinate input sensor 1 to designate which part of information should be displayed on the screen of a display device 2. That is, the signal value indicating whether the user touches the coordinate input sensor or not and the coordinate value for this touch are obtained by the coordinate input sensor 1. They are inputted to a rotation extent calculating circuit 4 to calculate the number of rotations for user's finger rotation, and the number of increase/reduction of the value is obtained. It can be controlled in accordance with the size of a circle described by the user. The extent of increase/reduction of the value obtained in this manner is inputted to an information retrieval processing device and is displayed on the screen of the display device 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotation amount input device using a coordinate sensor, and more particularly to a coordinate input sensor for detecting a coordinate designated by a user and a calculation for calculating a rotation amount from the detected coordinate value. And an input device configured to include the calculated rotation amount as an input value.

2. Description of the Related Art In a radio channel selection device, when designating a target broadcasting station frequency, when designating a target frame in a video tape, a word processor displays which part of a long document is displayed on the screen. There are many cases in which the user continuously specifies a continuous value, such as whether to specify whether or not to specify the alarm time of the alarm clock.

The following methods are available for the user to specify such continuous values. ． A method of directly specifying the value with a numerical value. ． A method in which the user designates while giving feedback by using the key switch to raise or lower the set value one by one or the key switch to raise or lower the set value greatly. ． A method of designating a value by providing a sliding indicator corresponding to the value, for example, a linear volume. ． There is a method in which a knob or a disk-shaped dial is provided and a user rotates the dial to specify the dial.

Such a dial is composed of a rotating disk or knob, and a portion which optically or magnetically detects the rotation of its rotating shaft and generates a pulse number according to the amount of rotation. By using such a dial, it is possible to quickly and accurately specify a target value while giving feedback to the user.

[0005]

However, in the above-mentioned conventional method, since feedback cannot be applied to the user's input, if the numerical value is not known in advance, the target value should be specified. Is difficult

In the method (1), when the target value is far from the current set value, it is necessary to press the key switch many times, and the target value cannot be specified quickly.

In the method of (1), since the maximum value and the minimum value are predetermined on the indicator, if the range of the value is large, the value changes greatly even if the indicator is operated a little, and it is subtle. Adjustment becomes difficult.

In the method (1), the mechanism is complicated,
It was difficult to make it lightweight.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an input device which is small in size, light in weight, and can be satisfactorily designated such as a dial. is there.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

[0011]

In order to achieve the above object, the present invention provides a coordinate input sensor such as a touch sensor,
The most main feature is that it is composed of an arithmetic means for calculating the rotation amount from the coordinate values.

[0012]

According to the above-mentioned means, the user rotates the finger or the like on the coordinate input sensor to specify the coordinate value, and the coordinate value specified by the user is detected by the coordinate input sensor. By calculating the rotation amount from the coordinate values and changing the set value, it is possible to realize the same function as the dial.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an overall external configuration of a portable information display device such as an electronic dictionary according to an embodiment of the present invention, and FIG. 2 shows an internal configuration of the portable information display device shown in FIG. It is a block diagram. 1 and 2, 1 is a coordinate input sensor (for example, a touch sensor), 2 is a display device, 3 is a rotation amount input device, 4 is a rotation amount calculation circuit, and 5 is an information retrieval processing device.

Next, the operation of the portable information display device of this embodiment will be described with reference to FIGS. 1 and 2.

The user rotates the finger to the right or to the left on the input section composed of the coordinate input sensor 1,
The screen can be scrolled up and down to specify which portion of the information is displayed on the screen of display device 2.

That is, the coordinate input sensor 1 obtains a signal value indicating whether or not the user is touching the coordinate input sensor 1 and the coordinate value when the user is touching the coordinate input sensor 1. This is input to the rotation amount calculation circuit 4, the rotation amount when the user rotates the finger is calculated, and the increase / decrease amount of the value is obtained.

It should be noted that the increase / decrease value can be adjusted according to the size of the circle drawn by the user, so that more satisfactory designation can be made. The increase / decrease value of the value thus obtained is input to the information search processing device 5 and displayed on the screen of the display device 2.

As can be seen from the above description, according to this embodiment, the user can satisfactorily indicate the target value while obtaining the feedback value. Further, since it has no mechanism portion and can be easily made small and lightweight, it is suitable as an input device for portable equipment or remote control equipment. Further, when not used as a value input device, it can be used as another user input device such as recognizing a character drawn on the coordinate input sensor 1, so that a variety of input methods can be provided to the user.

The present invention has been specifically described above based on the embodiments, but it goes without saying that the present invention can be variously modified without departing from the scope of the invention.

[0021]

As described above, according to the present invention, the user rotates the finger or the like on the coordinate input sensor to specify the coordinate value, and the coordinate value specified by the user is used as the coordinate value. By detecting with the input sensor, calculating the amount of rotation from the detected coordinate values and changing the set value, it is possible to realize the same function as the dial, so it is compact, lightweight, and can be specified well. can do.
