1. Field of the Invention
The present invention relates to an information processor, a control method, and a program.
2. Description of the Prior Art
Recently, information processors representatively including a smart phone, a cellular phone, an electronic information terminal, a Personal Digital Assistant (PD), a notebook Personal Computer (PC), and a tablet PC are rapidly coming into wide use. Some information processors include a display equipped with a touch panel function to improve operability. In the display including the touch panel function, the display area is also used as the touch area in general. Further, personal computers in a construction capable of changing the operation mode between the notebook mode and the tablet mode are also coming into broad use.
In an information processor on which a display including the touch panel function is mounted, gesture of a finger or a stylus pen is detected via a touch panel display. The information processor operates according to the gesture thus detected. The basic operation of the information processor is implemented by an Operating System (OS) such as Windows (registered trademark) installed in the information processor.
In a tablet PC, the liquid-crystal display as a display thereof includes the touch panel function. Hence, information can be inputted without using a hardware keyboard and the like. In such tablet PC, information pieces such as letters and characters are mainly inputted via the touch panel. That is, the PC has a high degree of freedom with respect to the size and the shape of the PC itself. This leads to an advantage of superior browsing performance in presenting information on the display.
Heretofore, the information processors such as personal computers have primarily processed data of characters inputted from hardware keyboards. In processing of images, the mouse has been primarily employed. Recently, tablet PCs capable of conducting the pen input operation are increasingly used. The tablet PCs are devised in consideration of the image of a pen and a sheet of paper for use in the daily life. That is, the tablet PCs include no hardware keyboard. In the tablet PCs, in addition to the input of images and drawings, the character input is possible through operation similar to the operation to write characters on a sheet of paper. Hence, the tablet PCs are familiar tools for the users of the generation who are familiar with the tablet PCs and who have not a long experience of the character input operation from the hardware keyboard.
The tablet PCs provide a particular input operation called “pinch out” in which pointers are dragged in mutually opposing directions to be apart from each other to widen an area surrounded by pointers, to thereby display a magnified image. Such multi-touch operations include flick, swipe, and pinch-in. The flick is an operation in which an operation to click a pointer and an operation to move a pointer are simultaneously carried out. The swipe indicates an operation to be used, for example, in the screen scrolling operation such that after the pointer is removed from the tablet, the screen scrolling continues. The pinch-in is an operation reverse to the pinch-out. When the pointers are dragged in the direction to approach each other, the area surrounded by pointers is reduced, to thereby display a contracted image.
In the tablet PC including a touch panel display to input handwritten letters, the operation to input letters from a keyboard (software keyboard) displayed as an image on. the touch panel display is employed together with the operation to input handwritten letters depending on cases. The software keyboard is a keyboard image presented on the display in which key images corresponding to the Japanese cursive syllabary or hiragana or the angular Japanese phonic syllabary or katakana and. alphabetic letters are arranged in predetermined orders, specifically, in the order of the Japanese syllabary and the alphabetic order. When a key on the keyboard image thus displayed is indicated by a pointing device, the function of the key is implemented like when a key is depressed in the hardware keyboard.
According to this technique, in place of the use of the hardware keyboard and the mouse as in the PCs of the prior art, there is provided a method of inputting sentences in which characters and letters are inputted through the handwritten letter recognition or by use of the software keyboard on the screen. However, the letter input speed in the handwritten letter recognition is restricted by, for example, the input speed of handwritten letters and the recognition error correction by the PC at erroneous recognition of handwritten letters. In the character input method using the software keyboard, it is required to correctly and continuously input letters from. the small software keyboard displayed on the screen. This leads to a problem that the operation to input letters and to convert the letters takes a long period of time and causes fatigue of user's optic nerves.
On the other hand, when a hardware keyboard is employed, it is possible to carry out an operation called shortcut. The shortcut is a function in which a command can be executed, without opening a menu, by use of a combination of a special key other than the ordinary keys and an ordinary key. In general, the shortcut function is set to operations to be frequently used, for example, copy and paste operations.
For example, in an application of Windows (registered trademark), when the user presses a particular ordinary key while pushing Ctrl key as a special key, a particular command can be executed by use of the hardware keyboard without selecting an associated command from the menu. This leads to advantages that the operation efficiency is improved through a simpler operation when compared with the situation in which the mouse is employed for the operation.
Under these circumstances, Japanese Patent Pub. No. 3385965 describes an information terminal. In operation of the information terminal, in a state. wherein a range of a character string “123456789” is selected and is displayed in a reversing display mode, when the pen is kept in contact with the position of character “9” on the transparent touch panel, the hold operation is assumed and a shortcut menu to conduct a plurality of operations (cut, copy, and the like) which can be conducted for the character string is displayed in the neighborhood of the character string “123456789”. In the situation in which the shortcut menu is displayed, when the pen is removed from the transparent touch panel, the shortcut menu is kept displayed. Hence, when a cut operation is tapped in the shortcut menu by the pen, the character string “123456789” is cut out to be stored in a buffer memory.
However, in the tablet PC of the prior art, most information pieces such as characters are basically inputted by using the dominant hand of the user as described above. Hence, when compared with a situation using the hardware keyboard in which both hands are used to conduct operations, there arises a problem that the user cannot conduct the intuitive operation of the shortcut function, which is available when the hardware keyboard is employed. Particularly, when the tablet PCs are introduced, the users having a long experience of the character input operation from the hardware keyboard will not be satisfied with operability of the tablet PC because they cannot operate the shortcut function with which they are familiar.
In the technique described in Japanese Patent Pub. No. 3385965, the user conducts all operations basically by use of only the dominant hand such that after the range for the operations of “cut”, “copy”, and the like are conducted, a shortcut menu is displayed to carry out a desired operation. However, the shortcut function is accomplished only through the input operations by using the dominant hand on the touch panel display not including the hardware keyboard. This results in a problem that the operation of the shortcut function using the dominant hand is not easy for the users having a long experience of the character input operation using both hands from the hardware keyboard.
It is therefore an object of the present invention, which has been made in consideration of the problems above, to provide an information processor, a control method, and a program wherein in an information processor including a touch panel display, it is possible, by disposing an auxiliary user interface, to implement the shortcut operation conventionally accomplished on the hardware keyboard, to thereby improve operability based on intuitive operation of the tablet terminal.
In one or more embodiments of the present invention, there is provided an information processor including:

In accordance with the present invention, there are provided an information processor, a control method, and a program wherein it is possible to implement the shortcut operation conventionally accomplished on the hardware keyboard, to thereby improve operability based on intuitive operation of the tablet terminal.
The objects and features of the present invention will become more apparent from the consideration of the following detailed description taken in conjunction with the accompanying drawings in which:
Referring next to the drawings, description will be given in detail of one or more embodiments of the present invention. In the drawings, the same or corresponding constituent components are assigned with the same reference numerals, and description will be briefly given of such components or description thereof will be avoided according to necessity. In an information processor in accordance with the present invention, it is possible to implement the shortcut operation conventionally accomplished on the hardware keyboard, to thereby improve operability based on intuitive operation of the tablet terminal. The information processor includes:
Referring now to
The configuration shown in
The ROM 101 is employed to store therein programs to control overall operation of the personal computer 100. The RAM 102 is a storage area in which programs stored in the ROM 101 are to be loaded. The HDD 103 is used to store therein application software of the personal computer 100 and to record therein contents such as Television (TV) programs received by a TV tuner, not shown. The power supply 104 supplies Alternating Current (AC) power or Direct Current (DC) to the personal computer 100. The network connecting section 105 is connected to networks such as interact, not shown, to serve as an interface for the networks. The CPU 106 controls the overall operation of the personal computer 100 and loads in a memory a control program stored in the ROM 101 and develops in the RAM 102 various data items obtained through operations of the personal computer 100.
The touch panel display 111 includes a Liquid Crystal Display (LCD) 107, a touch panel section 108, a special key section 109, and an operation menu display section 110. The LCD 107 configures a device to display results of information processing executed by the personal computer 100. The touch panel 108 provides a contact input function. Specifically, when the touch panel 108 senses pressure, static electricity, or the like applied thereto through input operations by a finger, a stylus pen, or the like, it supplies data of the pressure to the CPU 106. In the personal computer 100, input operations can be conducted by use of the touch panel section 108 in place of the operation input devices such as the hardware keyboard and the touch pad. Specifically, data items and commands can he inputted through an operation in which characters are directly written by bringing a finger or a stylus pen, not shown, into contact with the touch panel 108.
The special key section 109 is a tool to conduct a special key operation and is kept displayed in any situation on the right or left side of the touch display panel 111, which will be described later. In the operation menu display section 110, when an operation to retain or hold a tapped (contact) state of a special key (button) is carried out in the special key section 109, which will be described later, flick commands (operation menu) are displayed in a peripheral area of the flick button (special key) by dividing the area into a predetermined number of subareas. When the user leaves the linger from the special key, the flick commands (operation menu) vanish from the screen. The PC includes a function as below. Assuming, for example, that a hardware keyboard is connected to the PC 100, when a code generated through an operation in which one special key and any one of the ordinary keys, for example, “Ctrl” button and “c” button are simultaneously depressed is received, the PC 100 executes a command corresponding to the code.
Next, referring to
In the personal computer 100 placed in the landscape orientation, the special key section 109 is kept displayed in any situation on the lower-left area (in
Depending on the utilization state, it is possible for the user to change the display position of the special key section 109 by a single operation of a button. Although it is assumed in the description that the special key section 109 is placed on the left or right side as shown in
As a result, it is possible that for example, the right-handed user operates icons and windows as main or primary operations on the touch panel display 111 by fingers of the right hand and operates the special key section 109 placed on the left side of the touch panel display 111 as subordinate or cooperative operations by fingers of the left hand. In contrast, it is possible that the left-handed user operates icons and windows as main operations on the touch panel display 111 by fingers of the left hand and operates the special key section 109 placed on the right side of the touch panel display 111 as subordinate operations by fingers of the right hand.
The special key section 109 is kept presented on the touch panel display 111 in any situation. Hence, icons and the like concealed by the special key section 109 on the touch panel display 111 are not easily recognized in some cases. To prevent the disadvantageous situation, the special key section 109 may be presented as a semitransparent image on the touch panel display 111.
Referring next to
In
For example, there exists a shortcut key to call a function of Windows or software on a Windows PC in place of selecting the function from a menu. For example, when the user depresses the c key of the alphabet keys while pressing the Ctrl key as the special key, the selected character is copied. When the user depresses the v key of the alphabet keys while pressing the Ctrl key as the special key, the copied character is pasted onto the copy destination. Ordinary keys constituting commands which are executed by a combination of a special key and an ordinary key other than the special keys are displayed, when the user conducts an operation to hold the tapped state of a key in the special key section 109, in the periphery of the button of the special key section 109 by subdividing the periphery into a predetermined number of areas.
Although three special keys are disposed as an example in the configuration of
Next, description will be given of a display example of an operation menu displayed in response to an operation to hold the tapped state in the special key section of the information processor in the embodiment.
In
In
Next, when the user conducts an operation to hold special key “Ctrl” 401 of the special key section 109 in the tapped state, the flick commands ranging from underline 601 to copy 608 are displayed in the periphery of special key “Ctrl” 401. With the finger kept in contact with special key “Ctrl” 401, when the user conducts a flick operation to the area of the copy 608 and then removes the finger therefrom, the target area thus selected is copied (subordinate or cooperative operation). Thereafter, by bringing a finger into contact with the touch panel section 108, the user designates the copy destination area onto which the selected sentences are to be copied. With the finger kept in contact with special key “Ctrl” 401, when the user conducts a flick operation to the area of the paste 606 and then removes the finger therefrom, the selected sentences are copied onto the designated area.
That is, in the special key section 109, when an operation to hold a special key in the tapped state is conducted, the operation menu corresponding to the special key is displayed in the periphery of the special key by subdividing the periphery into a predetermined number of subareas. When the user selects an operation menu item from the operation menu thus displayed in the subdivided areas and conducts a flick operation to the area in which the selected operation menu item is displayed and then removes the finger therefrom, the processing associated with the selected operation menu item (coordinates) is executed.
As above, the flick commands are displayed when the user conducts an operation to hold one of the special keys 401 to 403 of the special key section 109 in the tapped state. Specifically, assuming that a hardware keyboard is connected to the personal computer, the system displays in the periphery of the special key a command menu from which the user can select a command to be executed corresponding to a code generated in response to an operation in which the special key and an associated normal key are simultaneously operated, in conformity with the combinations determined in advance.
In the initial setting of the personal computer 100, the flick commands may be assigned to each special key in an asymmetric way such that the assignment of the commands is set in a symmetric way later by the user. As shown in
In the arrangement in which the special key section 109 is placed in the right or left side of the touch panel display 111, to facilitate the flick operation by a finger of the right or left hand, it is also possible that by operating a changeover button, not shown, the allocation of the flick commands to the special keys may be reversed at a time. Specifically, the flick commands on the left side and those on the right side are replaced with each other. Further, to visually indicate a special key touched by the finger and flick commands, the background of the selected special key and that of the flick commands under the flick operation may be colored or the colors of the backgrounds may be changed.
Next, description will be given of an operation of the information processor in the embodiment the present invention.
S1002 judges whether or not the operation to hold the tapped state of a special key of the special key section 109 has been conducted. If the operation has not been conducted (no in S1002), the processing is terminated. If the operation has been conducted (yes in S1002), control goes to S1003.
In S1003, an operation menu corresponding to the special key for which the operation to hold the tapped state has been conducted is displayed in the peripheral area of the special key by dividing the peripheral area into a predetermined number of subareas. As described above, the operation menu displayed in the subdivided areas is a command menu from which the user can select a command to be executed corresponding to a code generated in response to an operation in which the special key and an associated normal key are simultaneously operated when either one of the special keys 401 to 403 of the special key section 109 is tapped.
S1004 judges whether or not an operation menu item has been selected. The judgment is conducted based on an event in which an operation to hold the tapped state of a special key is conducted and a flick operation to an operation menu area is successively carried out and then the finger is removed from the screen. If no operation menu item has been selected (no in S1004), the processing is terminated. If an operation menu item has been selected (yes in S1004), control goes to S1005. In S1005, the operation menu item thus selected is executed. As a result, in a tablet PC, it is possible to establish an operation environment almost equal to that in which a shortcut function is conducted in a personal computer including a hardware keyboard.
The operations of the functional blocks constituting the information processor 100 of the embodiment shown in
As described above, in accordance with the present invention, there is provided an information processor in which it is possible to implement the shortcut operation conventionally accomplished on the hardware keyboard, to thereby improve operability based on intuitive operation of the tablet terminal. The information processor includes:
While the present invention has been described with reference to the particular illustrative embodiment, it is not to be restricted by the embodiment but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiment without departing from the scope and spirit of the present invention.
