Description

  The present invention relates to an information terminal and method for improving operability with respect to a conventional information terminal.

In recent years, with the active development of information terminals, tablet computers that control the display of a liquid crystal screen by using a touch panel integrated with the liquid crystal screen without using a mouse or a keyboard in the main body have appeared.
In such a tablet computer, although an intuitive input using a touch panel can be performed, since the operation range of the touch panel is limited, there is an aspect that the operability is lowered as compared with an information terminal having a mouse.

  For example, referring to FIG. 7, consider the scrolling of a Web page (FIG. 7 (1)) displayed on a liquid crystal screen. As shown in FIG. 7 (2-A), the left side of the web page is displayed on the liquid crystal screen of the tablet computer. At this time, when viewing the right side of the Web page is desired, the user slides a finger on the liquid crystal screen (touch panel) to scroll the Web page on the liquid crystal screen.

However, since the range in which the finger is slid is limited to the range of the touch panel, depending on the size of the touch panel, as shown in FIG. . In such a case, the user must repeat the slide to a desired location.
On the other hand, since the mouse can be operated to a wider range than the touch panel, it is not necessary to repeat the same operation when scrolling the Web page.

  In order to solve such a problem, it is conceivable to attach an external mouse. However, it is troublesome to carry the mouse sequentially. Therefore, for example, Patent Document 1 proposes a pointing device that controls the pointing of the display unit based on a movement vector indicating a shift between the first time video and the second time video supplied from the camera unit. Yes.

  Embodiments of the present invention will be described below with reference to the drawings.

[Appearance of information terminal 1]
First, the external appearance of the information terminal 1 of the present invention will be described with reference to FIG. The information terminal 1 of the present invention is a so-called tablet computer. Here, the tablet computer in the present embodiment is an information terminal having a display screen integrated with the main body, and the main body does not include a keyboard, and various inputs are made using a touch panel provided on the display screen. An information terminal to be performed.

Referring to FIG. 1, the information terminal 1 includes a main body 2.
The main body 2 has a flat outer shape and includes a control unit and a storage unit that control the information terminal 1. The flat plate-like main body 2 includes a display screen 3 that displays various types of information on one surface thereof, and includes a movement amount detection unit 4 on the back surface of the one surface.

The display screen 3 is a substantially rectangular liquid crystal display screen provided on the surface of the main body 2 and displays various types of information based on the control of the control unit. Here, the display screen 3 is provided with a touch panel that receives a touch operation from the user, and display control of the display screen 3 is performed based on the touch operation.
The movement amount detection means 4 is provided on the back surface of the display screen 3 of the main body 2 and detects the movement direction and movement distance (movement amount) of the information terminal 1. The movement amount detection means 4 may be, for example, a device that detects the movement amount of the information terminal 1 from the rotation amount of the ball like a mechanical mouse, and a light emitter and a light receiver on the bottom like an optical mouse. And the amount of movement of the information terminal 1 may be detected optically.

[Functional configuration of information terminal 1]
Next, the functional configuration of the information terminal 1 of the present invention will be described with reference to FIG.
The information terminal 1 according to the present invention includes a control unit 10 and a storage unit 20. The control unit 10 is a central processing unit (CPU) that controls the information terminal 1 in an integrated manner, and the storage unit 20 is a memory (RAM, ROM, flash memory) that stores programs and data executed by the control unit 10. ).

  The control unit 10 refers to programs and data stored in the storage unit 20 to realize the functions of the component movement amount calculation unit 11 and the command execution unit 13.

  The component movement amount calculation means 11 determines the horizontal direction (X direction in FIG. 1) and the vertical direction (Y direction in FIG. 1) of the information terminal 1 from the movement direction and movement distance of the information terminal 1 detected by the movement amount detection means 4. The movement direction (that is, the right direction or the left direction for the horizontal direction and the upward direction or the downward direction for the vertical direction) and the movement distance are calculated for each of the directions. In the following, the movement direction and movement distance in each of the horizontal direction and the vertical direction may be referred to as “direction component movement amount”.

  The command execution unit 13 displays the display screen based on the movement amount (movement direction and movement distance) detected by the movement amount detection unit 4, more specifically, based on the direction component movement amount calculated by the component movement amount calculation unit 11. 3 display is controlled. For example, the command execution means 13 scrolls the display information on the display screen 3 based on the direction component movement amount (scrolls horizontally based on the horizontal direction component movement amount, and sets the vertical direction component movement amount to Scroll vertically based on).

Here, when the movement amount detection means 4 is provided on the back surface of the display screen 3, the movement amount detection means 4 detects the movement amount of the information terminal 1 in a state not intended by the user. Scrolling may not be performed. Therefore, in the present invention, the command execution means 13 performs display control of the display screen 3 based on the amount of movement only when a command (predetermined operation, specific operation) for the main body 2 is received.
Such a command can be arbitrarily set, and an example thereof is shown in FIG.

  FIG. 3 is a diagram illustrating a setting table stored in the storage unit 20. Referring to FIG. 3, the setting table stores a command defining unit 21, a setting defining unit 22, and the like.

The command defining unit 21 defines the above command. For example, in the scroll display of the display screen 3, the movement amount detection means 4 detects the movement amount of the information terminal 1 in a state where a command “predetermined operation” “tap on the display screen 3 (touch panel)” is being performed. Done in case. Here, “tap” refers to a state in which the user is touching the display screen 3 (touch panel).
The command defining unit 21 may define not only a command for executing scrolling but also a command for executing other display control. In the present embodiment, for example, in a state where a command (specific operation) “two-point tap on the display screen 3 (touch panel)” is being performed, the display information on the display screen 3 is based on the lateral direction component movement amount. Enlargement / reduction control is performed, and display information switching control (return / advance) of the display screen 3 is performed based on the vertical direction component movement amount.

  Note that the command and the display control specified for the command can be arbitrarily set. As shown in FIG. 3, for a single command “two-point tap on the display screen 3 (touch panel)”. A plurality of display controls including display control based on the horizontal direction component movement amount and different display control based on the vertical direction component movement amount may be defined, and one display control for one command. It is good also as prescribing only. Further, the commands are not limited to operations on the display screen 3 (touch panel), but other operations on the main body 2 of the information terminal 1, for example, a predetermined button is provided on the information terminal 1, and the operation on the button is used as a command. Also good. Further, the display control defined for the command may be appropriately changed by the user of the information terminal 1.

  For example, various setting information such as a scrolling speed and a scrolling direction is defined in the setting defining unit 22. The setting defining unit 22 may be appropriately changed by the user of the information terminal 1.

Returning to FIG. 1, the command execution unit 13 executes various display controls defined in the command definition unit 21 based on the movement amount detected by the movement amount detection unit 4 and the command received from the user.
Although the display control by the command execution unit 13 is performed with a command as a trigger, the movement amount detection and the direction component movement amount calculation may be performed with a command as a trigger. That is, in the state where no command is received, the movement amount detection unit 4 may not detect the movement amount itself.

[Hardware configuration of information terminal 1]
The hardware of the information terminal 1 described above can be configured by a general computer. For example, a general computer includes a central processing unit (CPU) as the control unit 10, a memory (RAM, ROM, flash memory) as the storage unit 20, and various wired and wireless LAN devices as network communication devices. As the display screen 3, for example, various displays such as a liquid crystal display and a plasma display are appropriately provided. The information terminal 1 includes a touch panel and movement amount detection means 4 as input devices, which are connected by a bus line. In such a general computer, the CPU controls the information terminal 1 in an integrated manner, reads and executes various programs as appropriate, and cooperates with the hardware described above to realize various functions according to the present invention. is doing.

[Processing of information terminal 1]
Next, the processing of the information terminal 1 according to the present invention will be described with reference to FIG.

  First, the control unit 10 of the information terminal 1 determines whether or not a command has been received in order to prevent display control unintended by the user, that is, any command specified in the command definition unit 21 of the storage unit 20. It is determined whether it has been accepted (S1). When this determination is YES, display control of the display screen 3 is performed based on the movement amount detected by the movement amount detection means 4, as shown in S2 to S4. On the other hand, when this determination is NO, the control unit 10 ends the process, and thus display control of the display screen 3 based on the movement amount is not performed.

  In S <b> 2, the movement amount detection unit 4 detects the movement amount of the information terminal 1 based on the movement operation by the user and provides it to the control unit 10. Subsequently, the component movement amount calculation means 11 of the control unit 10 calculates the direction component movement amounts in the horizontal direction and the vertical direction, and provides them to the command execution means 13 (S3). Thereafter, the command execution means 13 of the control unit 10 performs display control of the display screen 3 based on the command received in S1 and the direction component movement amount provided in S3. Specifically, for example, when a scroll command is received, the command execution unit 13 scrolls display information on the display screen 3, and when an enlargement / reduction command is received, the command execution unit 13. The display information on the display screen is enlarged / reduced.

[Operation of information terminal 1]
Next, the operation of the information terminal 1 according to the present invention will be described with reference to FIGS.

  First, the scroll control of the display screen 3 will be described with reference to FIG. In FIG. 5 (1), the left part of the Web page shown in FIG. 7 (1) is displayed, and the user who is browsing wants to scroll the Web page to the right. Therefore, the user moves the information terminal 1 while performing a tap operation on the display screen 3 (touch panel). Here, as shown in FIG. 3, in this embodiment, the tap operation is a scroll command. Therefore, the command execution means 13 performs scroll control of the display information on the display screen 3 based on the movement amount (direction component movement amount) of the information terminal 1.

  At this time, in the information terminal 1 of the present invention, the scrolling of the display screen 3 can be performed within the range in which the information terminal 1 can move. You can scroll appropriately to the position. That is, in the information terminal 1 of the present invention, the scroll control of the display screen 3 can be performed beyond the slidable range of the touch panel.

  Next, enlargement / reduction control of the display screen 3 will be described with reference to FIG. In FIG. 6A, the information terminal 1 accepts a moving operation in the horizontal direction while accepting a two-point tap operation on the display screen 3 (touch panel). Here, as shown in FIG. 3, in the present embodiment, in a state where a two-point tap operation is performed, enlargement / reduction control is performed based on the amount of movement in the horizontal direction. Therefore, the command execution means 13 performs enlargement control of the display information on the display screen 3 based on the amount of movement of the directional component to the left side of the information terminal 1 (FIG. 6 (2)), and to the right side of the information terminal 1 The display information on the display screen 3 is reduced based on the amount of movement of the directional component (FIG. 6 (3)).

  Thus, in the information terminal 1 of the present invention, not only the scroll control for the display information on the display screen 3 but also the enlargement / reduction based on the movement amount detected by the movement amount detection means 4 provided on the back surface of the display screen 3. Since reduction control and the like can be performed, operability can be improved.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
