DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus, in particular, a display unit for displaying an operation screen based on given screen data, and a display unit arranged on the display surface of the display unit. An information processing apparatus comprising: a translucent touch panel that detects a contact and outputs the contact coordinates; and a control unit that supplies the screen data to the display unit and performs information processing according to the contact coordinates output from the touch panel. Related to the device.

[0002]

2. Description of the Related Art As an information processing device, such as a portable information processing terminal or a car navigation device, in which an input device such as a keyboard or a mouse is difficult to use, it is integrated on a display screen such as an LCD (liquid crystal display device). There is a type in which a touch panel is used as an input means, and the demand for this type of information processing apparatus tends to increase dramatically as the demand for miniaturization increases.

[0003] A touch panel has a transparent X electrode arranged in parallel in a vertical direction and a transparent Y electrode arranged in a horizontal direction in parallel on both sides of an elastic transparent pressure sensitive film. Are sequentially applied, and the X electrodes detect the drive pulse. When the touch panel is pressed, the pressure-sensitive film at the pressed position causes X
The resistance between the electrode and the Y electrode decreases, and a driving pulse is output to the X electrode. The position of the X electrode at which the drive pulse was detected;
The pressed coordinate position on the touch panel can be read based on the timing of the detected drive pulse.

In an information processing apparatus having such a touch panel, selection items are displayed on the LCD by icons or characters, and when this display object is pressed from above the touch panel, it is selected as an operation target display object. In many cases, it can be done.

[0005]

By the way, in the conventional information processing apparatus, the processing is performed by selecting selection items one by one using a finger or a dedicated touch pen. Therefore, in order to select and operate an item displayed on the LCD, in addition to the selection of the item displayed on the touch panel, a complicated operation using a combination of a direction key and an enter key is required.

The present invention has been made to solve such a problem, and an object of the present invention is to provide an information processing apparatus capable of performing complicated input processing with a simple operation using a touch panel. Aim.

[0007]

According to the first aspect of the present invention, when two points of contact coordinates are simultaneously output from the touch panel, the information is specified between the two points or on the two points on the screen. A display object displayed in the area is recognized as an operation target display object.

Therefore, according to the information processing apparatus of the first aspect, by touching two points on the touch panel simultaneously with a finger or the like, an input for designating a display object on the screen as an operation target display object is performed. be able to.

According to a second aspect of the present invention, when the distance between the contact coordinates of the two points received from the touch panel is equal to or less than a predetermined threshold value or when the distance from the value equal to or greater than the threshold value is reduced to the threshold value or less, The display object displayed between two points having a distance equal to or less than the threshold value or within the area of the screen designated by the two points is recognized as an operation target display object.

According to the information processing apparatus of the present invention, when a display object on the screen is to be specified as an operation target display object by touching the touch panel, two points separated from the display object by two points are set. It is possible to designate an operation target display object such that the two touch points are touched for the time being and the display object is corrected so that the display object can be accurately specified in the process until the distance becomes equal to or less than the threshold value. Therefore, it is possible to accurately specify the operation target display object.

This is extremely effective, for example, when the information processing device of the present invention is used in a car navigation device. This is because, for example, when driving a car navigation device and inputting it to a touch panel (touch panel display) as its monitor display and input device, the operation target display object on the screen is suddenly and accurately input with two fingers. This is because it may be difficult to touch, for example, both ends of the display object to be displayed. This is especially true when the vehicle vibrates. Therefore, when the coordinates of the two points are determined as specifying the operation target display object at the first time when the two fingers are simultaneously touched, a display object different from the intended one is specified as the operation target display object. In other words, for example, it is necessary to start over.

However, when two fingers are once brought into contact with the touch panel and then moved, it is easy to precisely control the position of the fingers on the touch panel. Therefore, a predetermined distance threshold (for example, 4 cm or 5 c
m) Touching two points at a distance greater than m), and adjusting the contact positions of the two points so that the displayed object can be accurately specified in the process of shrinking, can accurately specify the displayed object even during driving. it can.

When the vehicle is not running, for example,
It is sufficiently possible to directly and accurately touch, for example, both ends of a display object to be an operation target display object on the screen with two fingers,
In such a case, contacting two points at a large distance and requesting an operation to reduce the contact point deteriorates the operability. Thus, it is possible to directly specify the display object on the screen at two points, and it is possible to avoid such deterioration in operability.

According to a third aspect of the present invention, when the distance of the contact coordinates of the two points received from the touch panel is reduced, and the reduction rate exceeds a predetermined threshold, the distance between the two points or the two points in the screen is reduced. A display object displayed in the designated area is recognized as an operation target display object.

Therefore, according to the information processing apparatus of the present invention, when a display object on the screen is specified as an operation target display object by touching the touch panel, the display object is separated by a distance larger than the display object. It is possible to specify an operation target display object such that the user touches a point for the time being, corrects the two touch points, and corrects the display object in a process until the reduction ratio of the distance becomes equal to or less than the threshold value. Therefore,
It is possible to accurately specify the operation target display object. The significance is exactly the same as that of the information processing apparatus of claim 2.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a display unit for displaying an operation screen based on given screen data, and a display unit arranged on the display surface of the display unit, which detects contact with the display surface. A translucent touch panel that outputs the contact coordinates,
The present invention is directed to an information processing apparatus including: a control unit that supplies the screen data to the display unit and performs information processing according to contact coordinates output from the touch panel. When touch coordinates of a point are given, a display object displayed in an area of a screen designated by the two points is recognized as an operation target display object. It can be implemented in the form.

(1) When contact coordinates are input for two points, a designated area may be defined between the two points, or a rectangle having a diagonal line between the two points or a circle having a diameter. The screen inside of the designated area may be set as a designated area, and an operation target display object in the designated area may be selected.
In this case, an icon, text, or a location between two points in the map in the designated area is a display object as an operation target display object.

(2) When contact coordinates are input for two points, the contact coordinates of the two points are immediately referenced, more specifically, based on the contact coordinates of the two points touched first. The operation target display object may be recognized. However, when the distance between the two initially touched points is equal to or more than a predetermined threshold, the two points are not regarded as valid contacts and are not recognized as being effective. It may be considered that the effective contact is recognized by using the two points at the time of, and the contact coordinates of the two points may be used as a specific reference of the operation target display object. The significance is described in the description of the information processing apparatus according to claim 2. In this case, if the distance between the two initially touched points is equal to or less than the threshold value, the operation target display object is determined based on the contact coordinates of the two points.

(3) In the case where the contact between the two initially contacted points is regarded as an effective contact,
When the distance of the contact coordinates of the two points received from the touch panel is shortened and the shortening rate exceeds a predetermined threshold, the display object displayed between the two points at that time or in the area designated by the two points is operated. You may make it recognize as a display object.

(4) In the case where the operation target display object is recognized, when the contact coordinates of two points or one point continuously given from the touch panel move thereafter, a drag command is issued for the operation target display object. It should be recognized as having been received. This is because the information processing apparatus can have a drag function frequently used in a personal computer or the like.

(5) In the case where the operation target display object is recognized, after the operation target display object is further recognized as having received the drag command with respect to the operation target display object, the operation target display object is recognized. When there is no contact between two designated points or when another contact occurs between the two points, it is recognized that a specific command set in advance for the operation target display object has been commanded. It is good to do. This is because the dragged object must be copied or moved, for example, and a command is required, but the command is simply removed from the two points already in contact with each other or the two points in contact with each other. This is because it can be performed only by adding one more contact point in between. Note that examples of the specific command include copying and moving, but are not necessarily limited thereto, and other commands such as erasing may be used.

(6) After recognizing that the display object is an operation target display object and that the distance between two contact points continuously provided from the touch panel is large and the distance between them is large, the display is performed. Recognition of an object as an operation target display object may be canceled. This is because there is a case where the operation target display object is specified based on an error in the operation of specifying the operation target display object, a misunderstanding of the display object, or the like, and in such a case, the operation is performed. This is because after the recognition on the information processing apparatus side based on is completed, the recognition can be canceled and the user can be given an opportunity to redo the designation of the operation target display object.

(7) The recognized operation target display object may be enlarged and displayed at different positions on the screen of the display unit. This is because, when the operation target display object is small and difficult to see, it can be moved to an easy-to-view place and further enlarged to make it easier to see. This also gives
There is also an advantage that an item hidden by a finger can be easily confirmed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 is a circuit block diagram showing a schematic configuration of a first embodiment in which the information processing apparatus of the present invention is applied to a car navigation apparatus. In the figure, reference numeral 20 denotes a control unit of the car navigation device, which includes a CPU (Central Processing Unit), R
OM (Read Only Memory) or RAM (Random Access Memory).

Reference numeral 10 denotes a touch panel display which is a display provided with a touch panel capable of touch input, 2
1 is map data reading means, which includes, for example, an IC
(Integrated Circuit) Card or DVD (Digital Ver
A recording medium such as a satile disk) on which map data is written is mounted, and the map data stored in the recording medium is displayed on the touch panel display 10 by the operation of the control unit 20 and the like.

Reference numeral 22 denotes a GPS receiver which receives a GPS signal transmitted from a GPS satellite and detects the latitude and longitude of the current position of the vehicle equipped with the car navigation device. Reference numeral 23 denotes a self-contained navigation sensor, which includes an angle sensor such as a gyro for detecting a vehicle rotation speed, and a traveling distance sensor for generating a pulse at every constant traveling distance. From the outputs of the GPS receiver 22 and the self-contained navigation sensor 23, the precise position of the vehicle (vehicle equipped with the car navigation device) can be detected, and the position can be indicated on the map displayed on the touch panel display 10. Becomes 24 is a system bus.

FIG. 2 explains one function of this embodiment. The touch panel display 10 will be described in more detail with reference to FIG. The touch panel display 10 includes a control unit 20 (see FIG. 1).
For example, a touch panel is arranged on an LCD (Liquid Crystal Display) that displays an operation screen based on the screen data given by the user, and input can be performed by touching the touch panel. More specifically, transparent X electrodes are arranged in parallel in the vertical direction and transparent Y electrodes are arranged in the horizontal direction in parallel on both sides of an elastic transparent pressure-sensitive film. For example, drive pulses are sequentially applied to the Y electrodes, and X
The drive pulse is detected by the electrode, and the coordinate position of the contact point can be read based on the position of the X electrode where the drive pulse is detected and the timing of the detected drive pulse. As described above, since the touch panel portion is made of a transparent material, the screen of the display element composed of the LCD can be viewed as it is.

When using the touch panel display 10 to select a specific item 2 from the selection items such as icons and characters displayed on the screen, the surface of the touch panel display 10 is sandwiched between the selected items 2. Touch the two points 11 and 12 with a fingertip. Two fingertips 1
It is not necessary that the timings to contact the points 1 and 12 be the same. For example, the thumb may touch the point 11 and then the index finger may touch the point 12 while keeping the thumb in contact with the touch panel display 10. In this case, simultaneous contact with the two points 11 and 12 has started when the index finger contacts the point 12.

Further, with the thumb and the forefinger in contact with the touch panel display 10, they are moved to the points 11a and 12a, respectively, so that the distance between them is equal to or less than the threshold value L. As a result, the item 2 displayed on the screen inside the circle C having the center O as the center point of the straight line connecting the points 11a and 12a and having the diameter L as the threshold value L is "pinched" as the operation target display object. Selected. That is, the control unit 20 recognizes the item 2 as an operation target display object.
Then, the selected and recognized item 2 is enlarged and displayed in the enlarged display window W on the screen of the display 10.

Next, both or at least one of the thumb and the forefinger is moved to the points 11b and 12b, respectively, while keeping the touch panel display 10 in contact therewith. As a result, the “pinched” item 2 translates in the screen along the movement of the thumb and forefinger to the point 13. In the present embodiment, after the recognition of the operation target display object is performed, the drag is performed by pressing one of the two touching points.
If a point is in contact, the other point is effective even if it is not in contact. By moving the point in contact, the operation target display object can be moved. Item 2
Is moved to a predetermined position, and the person in contact with the touch panel display 10 of the thumb and the forefinger (if both the thumb and the index finger are touched and dragged) is released from the touch panel display 10. This causes item 2 to be “released” and its position to point 13
Is determined.

If there is an action (processing) that the released item 2 can take for the released position, that processing is performed. When there are a plurality of actions, from among the plurality of actions displayed on the display 10 screen,
The selection can be made by the touch panel display 10. Thus, it is possible to have a drag and drop function.

FIGS. 3A and 3B show the copy and transfer functions of this embodiment. (A) As shown by the dotted line in FIG. 3A, the range of the text (in this example, the character “Aiueo”) 3 to be copied or moved on the screen displayed on the touch panel display 10 is shown. The finger is traced from above the touch panel display 10 with the forefinger, and is further pinched with the thumb and forefinger. Thereby, the text 3 in the specified range is selected. Next, while the index finger and the thumb are in contact with the touch panel display 10, the user moves the index finger and the thumb to a place where the user wants to copy or move. At this time, one of the contacting thumb and index finger (for example, the thumb) may be separated from the touch panel display 10 as described above.

(B) Next, as shown in FIG. 3B, the index finger is released from the touch panel while the selected text 3 is moved to a predetermined location and displayed. This allows
The copy or move destination position is determined. Further, a copy or move action is selected. Thus, the selected text 3 is copied or moved to the determined position.

FIG. 4 shows the map mark moving function of this embodiment. As shown in FIG. 4, the upper and lower sides of the mark M to be moved are sandwiched between the thumb and the index finger on the touch panel display 10 and “pinch”. As a result, the area including the selected mark M is enlarged and displayed in the enlarged display window W, as shown in the upper left of the screen. Further, the user drags (moves) the touch panel display 10 on the touch panel display 10 while holding the mark M between the thumb and the index finger, and drops (releases) the target position. As a result, the mark M moves from the initial position to the target position.

FIGS. 5A and 5B show the route changing function of this embodiment. As shown in FIG. 5A, fixed points A and B, such as two intersections, are sequentially designated with a forefinger on a guidance route R displayed superimposed on a map. Thereby, the guidance route R between the fixed points A and B is selected. The guidance route R at the selected location is changed in color and line type to clearly indicate that the route is selected.

Next, as shown in FIG. 5B, one location of the guide route R selected on the touch panel display 10 is pinched with the thumb and the forefinger, and dragged and dropped to a target location. Thereby, the guidance route R is changed. The display of the changed guidance route R is returned to the normal color and line type.

FIG. 6 is a flowchart showing an example of the operation of the control unit of the car navigation device to which the information processing device of the present invention is applied. Hereinafter, the operation will be described with reference to FIG.

(S1) When the information processing apparatus is turned on and the operation is started, it is determined in step S1 whether or not the touch panel has a contact point. If there is no contact point, that is, if the determination result is No, the determination is repeated until a determination result of Yes is obtained. If there is a contact point on the touch panel, the process proceeds to step S2.

(S2) The judgment result of step S1 is Yes
At this time, it is determined whether or not there are two contact points. (S3) When the determination result of step S2 is No, that is,
If there is only one contact point, it is determined whether or not the location specified by the contact point is set as a designated area for instructing a predetermined action.

(S4) If the result of the determination in step S3 is Y
In the case of es, that is, when the action is set, the set action is executed, and thereafter, the process returns to step S1. If the determination result of step S3 is Yes, that is, if no action is set, the process returns to step S1.

(S5) The judgment result of step S2 is Yes
In other words, when two contact points are detected, it is determined whether or not the distance between the two detected contact points is equal to or smaller than a threshold. If the distance between the two contact points exceeds the threshold, the process returns to step S1, and if the distance is less than the threshold, the process proceeds to step S6.

(S6) If the decision result in the step S5 is Yes
In other words, if the distance between the two contact points is equal to or less than the threshold value, the coordinates of the two contact points are recognized as the coordinates specifying the operation target display object. Then, it is determined whether or not the displayed item exists in a circle or a rectangular area specified by the coordinates of the two contact points. If the result of the determination is No
In other words, if no item exists in the area, the process returns to step S1. Then, the result of the determination is Ye
In the case of s, that is, when an item exists in the area, the item is recognized as an operation target display object. (S7) Thereafter, dragging is performed on the screen. That is, when the contact point moves, the item enters an operation state in which the item moves accordingly.

(S8) Next, it is determined whether or not the touch point on the touch panel is continuously present. If there is a touch point, the flow returns to step S7 to continue the drag operation, and the movement of the touch point is performed. The display position of the selected item is moved. (S9) When the result of the determination in step S8 is No,
That is, the position of the item when the contact point disappears is recognized as the final movement position. In other words, the item is released, and the position of the item after the movement is determined.

(S10) When step S9 is completed, it is determined whether or not an action is set at the position where the item is released (the last position of the action). If the determination result is No, that is, if no action is set, the process returns to step S1. (S11) When the result of the determination in step S10 is Yes, it is determined whether the set action is plural (single).

(S12) If the decision result in the above step S11 is No, that is, if the set action is one (single), the set one action is executed. After execution of the action, step S1
Return to (S13) If the result of the determination in step S11 is Yes, that is, if a plurality of actions have been set, options are displayed.

(S14) Thereafter, it is determined whether or not an action is designated by touching one of the options with a finger, that is, whether or not the selection is made within a predetermined time. If the determination result is No, that is, if no selection has been made, the process returns to step S1. (S15) When the determination result in step S14 is Yes,
That is, when the action is specified, that is, when the selection is made within a predetermined time, the action related to the selection is executed, and thereafter, the process returns to step S1.

As described above, while the power of the information processing apparatus is turned on, the processing of steps S1 to S15 is repeatedly performed. Then, the operation is forcibly terminated by turning off the power.

As described above, the information processing apparatus of this embodiment has the following advantages. By touching two points on the screen of the touch panel display 10, an item displayed in the area of the screen specified by the two points can be selected. Further, by dragging the selected item,
It can be moved to a predetermined position or copied. Thus, complicated input processing can be performed by a simple operation of only the touch panel.

In this embodiment, as one of the actions, a function is provided for displaying the selected item in an enlarged display window on the screen. Thereby, there is an advantage that the item hidden by the finger can be easily confirmed.

The present invention is not limited to the above embodiment,
Various modifications are possible. For example, there are the following modifications. (1) In addition to a function of selecting an item in a screen area specified by two points on the touch panel display, a function of selecting a specific item by specifying one point may be provided in a conventional manner. it can. When two points are touched and there is no particular item between the two points, a straight line connecting the two points on the map may be the operation target display object.

(2) The area of the screen specified by the two points on the touch panel display is not limited to the circle of the threshold L centered on the midpoint of the two points. For example, it may be a circle whose diameter is a line connecting two points, or a rectangle or square whose diagonal is a line connecting two points. (3) The number of items in an area specified by two points is not limited to one, and a plurality of items may be selected at the same time.

(4) The present invention is not limited to the movement and copying of items, and may be configured to perform an arbitrary action such as deletion according to the processing contents of the information processing apparatus. (5) The input processing in this information processing device is not limited to a portable information processing terminal or a car navigation device.
The present invention can be similarly applied to an information processing apparatus such as a stationary personal computer.

(6) In the case where the operation target display object is recognized, after touching the screen after that or after further recognizing that the operation target display object has received the drag command. If the two points specifying the operation target display object lose their contact, or if there is another point contact between the two points, a specific command set in advance for the operation target display object is issued. It is good to recognize that it was instructed. That is because the dragged object must be copied or moved, for example, and a command is required, but by simply removing that command from two points that are already in contact,
Alternatively, it can be performed only by adding one more contact point between the two points. Note that examples of the specific command include copy and move, but are not necessarily limited thereto, and may be, for example, erase.

(7) In the case where the operation target display object is recognized by touching two points, and subsequently, it is recognized that the distance between the two touch points has increased, Alternatively, the recognition of the operation target display object may be invalidated, in other words, may be canceled. This is because the user may make a mistake in specifying the operation target display object or misunderstand the display object, and after the information processing device has finished recognizing the operation target display object, invalidate it. This is because it is preferable that the designation of the operation target display object can be performed again.

Therefore, the user touches two points with his / her finger or the like to specify an operation target display object, and when the specification is recognized by the information processing apparatus, the user feels the necessity of redoing thereafter. In that case, if you increase the distance between the two points,
Since the information processing apparatus invalidates the recognition, the designation of the operation target display object is cancelled. Accordingly, the user can again specify the operation target display object, or can perform another operation.
