FIG. 8 shows an example of a screen display when a numerical value such as a telephone number is input by a user's operation input. Numeral 511 is a numerical value in the middle of input, and the numerical value sequentially input at the current position 513 is added. Reference numeral 512 denotes a numerical value input panel, which selects and inputs a numerical value by tilting vertically and horizontally. Numeral 514 is a numerical panel on which a cursor 515 is moved by tilting left and right. The downward tilt operation selects the numerical value indicated by the current cursor, adds it to the end of the numerical value, updates 511, and moves the current position 513 to the right. Further, the upward tilting operation terminates the input and shifts to an operation such as making a call. If the mobile terminal is violently shaken, the input operation is canceled. In this way, it is possible to input a numerical value only by an operation such as tilting the mobile terminal without button operation.

FIG. 9 shows an example of a screen display when a character string is input by a user's operation input. Reference numeral 521 denotes a character string that is being input, and characters that have been sequentially input are added to the current position 523. Reference numeral 522 is a character input panel, which selects and inputs characters by tilting up, down, left, and right. Reference numeral 524 is a character panel on which a cursor 525 is placed.
Is moved by tilting left and right. Although the alphabetic character "JKLMNOPQR" is displayed in the figure, for example, when the cursor is on the R and further tilting motion to the right is detected, the character panel 524 is changed to "KLMNOPQRS" and the character S Display as if the cursor were on top of.
Further, by the downward tilt operation, the character indicated by the current cursor is selected, added to the end of the character string, 521 is updated, and the current position 523 is moved to the right. Further, the upward tilting operation terminates the input and shifts to an operation such as saving a memo. If the mobile terminal is violently shaken, the input operation is canceled.

In this way, it is possible to input a numerical value only by an operation such as tilting the portable terminal without button operation.

A method of selecting a menu or the like according to a user's operation input will be described with reference to FIG. Figure 10
Shows a screen display example when searching for a person from an address book and making an e-mail or a call. Reference numeral 534 is a person list display portion, and a cursor 535 on the person list display portion is moved by a vertical tilt operation. By tilting to the right, the telephone number associated with the person currently on the cursor is called and dialed. Further, by the tilting operation in the left direction, the e-mail address associated with the person currently on the cursor is called, and the mail transmission operation is started. If the mobile terminal is shaken violently, the menu selection operation is canceled. In this way, it is possible to select a menu only by an operation such as tilting the mobile terminal without button operation. Further, instead of selecting contents by icons, a list of contents stored in the mobile terminal may be displayed in a menu and the contents may be selected by the same method as described above.

With reference to FIG. 11, a method of simply replying to the received mail by the user's operation input will be described. Reference numeral 541 is a received mail display portion, and 542 is a simple reply setting panel. One of a plurality of reply messages registered in advance is displayed in 544, and another message is displayed by the left and right tilting operation. The tilting operation in the downward direction returns the currently displayed reply message to the sender of the received mail. If the mobile terminal is violently shaken, the simple mail reply operation is canceled. In this way, it is possible to make a simple reply to the received mail without button operation. (Embodiment 6) With reference to FIGS. 12 and 13, a method of displaying a screen on a mobile terminal without distinction between upper, lower, left and right will be described so as to be aligned with the normal position viewed from the user. A plurality of, for example, optical sensors 602 are arranged on the back surface of the body 601 of the mobile terminal. 603 is a view seen from the front when the user holds the mobile terminal in his hand, and 604 is a view seen from the back at this time. The part where the optical sensor is hidden by the user's hand and the part not covered by the user are detected, and the normal position seen from the user is detected. FIG. 13 shows a screen display example. Reference numeral 605 denotes a detection pattern of the optical sensor. A black circle 606 indicates a sensor which is not hidden and a white circle 607 indicates a sensor which is hidden. Here, the center of the sensor that is not hidden is detected, and the direction from the center of the mobile terminal to the center is defined as the normal position 611 from the user. As shown at 608, a screen is displayed so that the upper part of the display of the mobile terminal is aligned with the normal position. The right view of FIG. 13 shows an example when viewed in a tilted manner. In this way, the screen can be displayed in the normal position viewed from the user even if the mobile terminal is not distinguished from the top, the bottom, the left, and the right in any direction. In addition, for example, the content of the content may be changed and displayed depending on the direction in which the mobile terminal has different directions such as an ellipse. In addition to the optical sensor, it can detect that the user's hand is in contact with the mobile terminal.
For example, other devices such as a pressure sensor or a touch sensor may be used. (Embodiment 7) A method of displaying contents by classification will be described with reference to FIG. An example in which icons of major categories are displayed at 650 is shown. For example, icons such as email, music content, and news are displayed. Then, if these icons are selected, 65
Icons that are sub-classified as indicated by 1, 652, 653 or icons indicating the content itself are displayed. If the mobile device is shaken violently at this time,
It returns to the icon display of the upper major classification again and displays another small classified icon. In this way, by displaying a large amount of contents hierarchically, it becomes possible to select and browse desired contents only by tilting operation. Also, instead of using icons of major categories, for example, 651
When the mobile terminal is violently shaken when the icon of the small category is displayed, the icon of the next small category (for example, 652) may be displayed. (Embodiment 8) With reference to FIG. 15, a portion where an acceleration sensor is mounted in a mobile terminal will be described. As an acceleration sensor, there is a sensor which is currently known and which detects acceleration in the directions of two axes. In this case, the body 67 of the mobile terminal
When it is mounted at a position 671 away from the center of 0, the movement of the mobile terminal can be detected most effectively. 672
Is an example in which a sensor 674 is mounted on a board 673 mounted inside a mobile terminal. When using three sensors that detect acceleration in the 1-axis direction, as shown in 675, when the mobile terminal is viewed from above, a sensor that detects the acceleration in the left-right direction is located at 676 and vertically. The movement of the mobile terminal can be detected most effectively by mounting the sensor for detecting the acceleration of the axis of the direction in 677 and the sensor for detecting the acceleration in the front-rear direction at the position of 678. (Embodiment 9) With reference to FIG. 16 and FIG. 17, description will be given of a method capable of searching and browsing the same contents as above without using an acceleration sensor.

FIG. 16 shows an example in which a track pad 701 is mounted on the back surface of a portable terminal. By replacing the time series pattern of the input operation of the trackpad in the horizontal and vertical directions with the time series pattern of the XY axes of the acceleration sensor described above, similar contents can be searched and browsed without using the acceleration sensor.

FIG. 17 shows an example in which a touch panel 711 is mounted on the front surface of the display of the portable terminal. Horizontal and vertical time series patterns of touch panel input operations
By replacing with the time-series pattern of the XY axes of the acceleration sensor described above, similar contents can be searched and browsed without using the acceleration sensor. (Embodiment 10) A method of turning on the power supply of a portable terminal will be described with reference to FIGS.

FIG. 18 shows the upper part of the portable terminal in the arrow direction 721.
The electrodes are mounted inside so that they will be energized when rotated. In this way, it becomes possible to design the mobile terminal while maintaining a simple shape without disposing a new button on the mobile terminal. FIG. 19 is an example in which a terminal 731 is provided on the back surface of the mobile terminal so as to energize when two points are simultaneously touched by a finger or the like. By disposing one or a plurality of such terminal sets 731, it becomes possible to turn on the power supply when the mobile terminal is held in the hand. In each case, as is generally known,
If no input operation is performed for a certain period of time, the power may be turned off. (Embodiment 11) A method of enlarging / reducing the screen when the portable terminal is moved up and down will be described with reference to FIG.
The main body 741 of the mobile terminal is provided with an acceleration sensor that detects a vertical movement (perpendicular to the display of the mobile terminal). When the mobile terminal is moved in the upward direction 742, the content is enlarged and displayed as indicated by 744, for example. On the other hand, when it is moved downward 743, for example, 74
The content is reduced and displayed as shown in FIG. In this way, the contents can be enlarged / reduced by the movement of the mobile terminal without using buttons. (Embodiment 12) A method for adjusting the speed at which the mobile terminal is moved and the speed at which the icon moves will be described with reference to FIG. As indicated by 810, the horizontal and vertical movement speeds of the icons are directly proportional to the horizontal and vertical angles of the mobile terminal obtained from the acceleration sensor. The relationship between the angle of the mobile terminal and the moving speed at this time is R
Stipulated in. That is, the larger R is, the faster the moving speed of the icon becomes by just tilting the mobile terminal a little. On the other hand, as an example of detecting an operation such as shaking the mobile terminal violently, there is a method of checking the time during which the mobile terminal vibrates violently from the time series pattern of the acceleration sensor, as indicated by 820. One parameter at this time is the duration T of vibration. Reference numeral 810 is a screen display example for setting these R and T speeds. The value of R803 or T804 is set by moving the mobile terminal in the vertical direction to set the parameter to be set (speed of the icon or speed of vibration) and moving in the horizontal direction. In this way, the speed of movement of the icon, the speed of vigorous shaking, etc. can be set for each user. Further, when the normal icon group is displayed, R may be sequentially changed by using T when the icon is violently moved.

[0031]

According to the present invention, the user tilts the mobile terminal in the front-back and left-right directions until the desired icon appears on the screen, and keeps the mobile terminal horizontal when the desired icon is displayed near the center of the screen. Only by doing so, it is possible to search and browse information without performing complicated button operations and input operations.
