Description

  The present invention relates to a portable information terminal suitable for, for example, a mobile phone or a PDA (Personal Digital Assistant).

  2. Description of the Related Art Conventionally, portable information terminals such as mobile phones and PDAs have a display device made of liquid crystal or the like. In recent years, portable information terminals can display not only characters but also various information such as images on the display screen of the display device.

  FIG. 11 shows a schematic appearance of a so-called foldable mobile phone terminal as an example of the mobile information terminal. This foldable mobile phone terminal is a terminal in which a first casing 101 and a second casing 102 can be folded into two at a hinge portion 104. In the example of FIG. 11, a display unit 103 is provided in the first housing 101, and a key operation unit such as a numeric keypad is provided in the second housing 102.

  Here, in the case of the mobile phone terminal of the example of FIG. 11, the user often uses the second casing 101 provided with an operation unit such as a numeric keypad in his / her hand. Therefore, the image displayed on the screen of the display unit 103 of the mobile phone terminal is displayed so as to be arranged in consideration of the usage form of the mobile phone terminal, that is, as shown in FIG. In general, the screen is displayed so as to stand upright when the housing 101 is in the up state and the second housing 102 is in the down state. Note that the mobile phone terminal may be used in a horizontal state as shown in FIG. 13, for example. In the case of the conventional mobile phone terminal in the usage pattern shown in FIG. 13, the display on the screen of the display unit 103 is performed in the same manner as in the example of FIG.

  On the other hand, in Japanese Unexamined Patent Publication No. 2001-265309 (Patent Document 1), portable information that detects the direction of gravity and rotates the projection direction on the display surface based on the detected direction of gravity. A reader is disclosed. According to the portable information reading device described in this publication, information is always displayed on the screen in an easily viewable state regardless of the orientation of the device.

JP 2001-265309 A (FIG. 4)

  However, as described above, the portable information reading device described in Patent Document 1 is configured to adjust the projection direction of information displayed on the display surface based on the direction of gravity. For this reason, for example, when the orientation of the device is changed while maintaining the horizontal direction with respect to the direction of gravity, the projection direction of the information on the display surface does not change at all, and the information is not always easy to see. It is hard to say that is displayed.

  By the way, the portable information terminal includes, for example, an upper casing provided with a display unit, a key operation unit on the surface in the same direction as the display surface of the display unit, in addition to the folding type terminal as described above. There are also terminals (hereinafter referred to as “rotary open type terminals”) in which the lower casings provided are rotatable in the horizontal direction around a rotating mechanism provided at one end of each casing. In the case of this rotary open type terminal, not only when the terminal is opened but also when the terminal is closed, the display unit is always exposed to the outside. Therefore, the usage mode of the terminal by the user may be, for example, when the terminal is opened or closed, when used between the terminals, or when the terminal is level with respect to the direction of gravity. Various usage forms such as use in a state where only one of the casings is rotated are assumed. Further, in the case of the rotary open type terminal, it is considered that the direction when the user views the screen of the display unit is also various directions. Therefore, in particular, in a portable information terminal that is assumed to be used in various forms such as a rotary open type terminal, it is desired to be able to display information in a state that is always easy to see on the display unit. Yes.

  The present invention has been proposed in view of such circumstances, and displays information in a state that is always easy to see on the display unit when, for example, a rotary open type terminal is assumed to be used in various forms. It is another object of the present invention to provide a portable information terminal capable of recognizing the display and operation of the terminal as originally intended.

  According to the portable information terminal of the present invention, when the display on the display unit is controlled based on the output value from the predetermined sensor, the output value of the predetermined sensor is set according to the detection output of the arrangement state detecting means. By correcting, the detection value of the arrangement state detecting means is reflected on the display on the display unit.

  In the present invention, when use in various forms is assumed, such as a rotary open type terminal, the arrangement state detection is performed when the display on the display unit is controlled based on the output value from a predetermined sensor. By correcting the output value of a predetermined sensor in accordance with the detection output of the means, information can be displayed on the display unit in an easily viewable state, and the display and operation of the terminal can be recognized as originally intended.

[Sensor and layout, sensor output usage example and correction example]
Hereinafter, an arrangement example of the geomagnetic sensor 24 which is an example of the terminal state detection sensor 52 and an angle sensor 23 which is an example of the terminal form detection sensor 54, a specific usage example of the output value of the geomagnetic sensor 24, A specific example when the output value is corrected by the output of the angle sensor 23 will be described with reference to FIGS.

  FIG. 5 shows a specific arrangement example of the geomagnetic sensor 24 and the angle sensor 23. In FIG. 5, the angle sensor 23 is attached to the rotary shaft 22 of the rotary hinge mechanism of the mobile phone terminal of this embodiment. Therefore, the output value from the angle sensor 23 is the rotation angle when the rotary hinge mechanism rotates, that is, the relative angle between the upper casing 1 and the lower casing 2 in the rotary open type mobile phone terminal of the present embodiment. In other words, it is a value that allows grasping the shape of the terminal.

  On the other hand, the geomagnetic sensor 24 is fixedly provided inside the lower housing 2 of the mobile phone terminal of the present embodiment. Therefore, the output value of the geomagnetic sensor 24 is a value indicating how much the mobile phone terminal of the present embodiment is inclined with respect to the geomagnetism, more precisely a value indicating the direction of the lower housing 2 with respect to the geomagnetism. .

  Here, as an example of a specific method of using the output value of the geomagnetic sensor 24, an example in which a map image corresponding to an orientation is displayed on the display 3 as shown in FIG. That is, when a map image is displayed on the display 3, if the orientation detected by the geomagnetic sensor 24 and the display orientation of the map image are matched, the user can display the map image displayed on the display 3. Thus, it becomes possible to recognize which direction is north, for example. The example in FIG. 6 is a map image when the upper side of the display 3 (side where the speaker 4 is provided) is in the north direction when the mobile phone terminal of the present embodiment is in the open state. Is a display example.

  By the way, as described above, in the mobile phone terminal in which the geomagnetic sensor 24 is arranged inside the lower housing 2, for example, only the upper housing 1 is rotated without moving the lower housing 2 from the open state of FIG. 6. In this case, the display orientation of the map image on the display 3 does not change. That is, in this case, only the upper housing 1 rotates, so that the actual orientation on the upper side of the display 3 (the side on which the speaker 4 is provided) is no longer the north orientation, As in the example of FIG. 6, a map image is displayed with the side on which the speaker 4 is provided remaining in the north orientation. Therefore, in this case, the display orientation of the map image on the display 3 is different from the actual orientation, which causes confusion to the user. If the user knows the actual orientation, the actual orientation and the display orientation of the map image can be matched if the user changes the orientation of the mobile phone terminal to match the actual orientation. If the user does not know the actual orientation, there is no way to deal with it.

  For this reason, as shown in FIG. 5, the mobile phone terminal of the present embodiment includes a correction unit 53 that corrects the actual orientation measurement value by the geomagnetic sensor 24 using the output value of the angle sensor 23. The direction measurement value corrected by the correction unit 53 is sent to the control unit 41.

  Here, with the lower casing 2 as a reference, the rotation angle of the upper casing 1 relative to the lower casing 2 is referred to as an offset rotation angle, and the offset rotation angle in the open state of FIG. The left rotation of the upper housing 1 with respect to 2 is referred to as left offset rotation, and the right rotation of the upper housing 1 with respect to the lower housing 2 is referred to as right offset rotation.

  A specific example will be described below. In the open state of FIG. 6, the geomagnetic sensor 24 in the lower housing 2 indicates that the upper side of the display 3 (side on which the speaker 4 is provided) is the north direction. An azimuth measurement value is output, and a value indicating an offset rotation angle of 0 degrees is output from the angle sensor 23. In this case, the azimuth measurement value with a correction amount of 0 is output from the correction unit 53 to the control unit 41. Will be sent to. And the control part 41 determines the display azimuth | direction of the map image displayed on the display 3 based on the said azimuth | direction measurement value. Accordingly, the map image displayed on the display 3 at this time is a map image with the upper side of the display 3 (side on which the speaker 4 is provided) oriented in the north as shown in FIG.

  Further, for example, when only the upper housing 1 is rotated to the left by, for example, approximately 90 degrees without moving the lower housing 2 from the open state of FIG. 6, the geomagnetic sensor inside the lower housing 2 is moved. On the other hand, the azimuth measurement value from 24 does not change, while the angle sensor 23 outputs a value indicating the left offset rotation angle 90 degrees. In this case, the correction unit 53 outputs the left offset rotation angle 90 degrees. The direction measurement value corrected by the amount is sent to the control unit 41. And the control part 41 determines the display azimuth | direction of the map image displayed on the display 3 based on such a corrected azimuth | direction measurement value. Accordingly, the map image displayed on the display 3 at this time is an image showing a correct orientation in which the offset rotation angle of the upper housing 1 is corrected as shown in FIG.

  On the other hand, when only the upper housing 1 is rotated to the right by, for example, approximately 90 degrees without moving the lower housing 2 from the open state of FIG. 6 (not shown), the geomagnetic sensor 24 in the lower housing 2 is omitted. On the other hand, a value indicating a right offset rotation angle of 90 degrees is output from the angle sensor 23. In this case, the correction unit 53 outputs the value corresponding to the right offset angle of 90 degrees. The corrected azimuth measurement value is sent to the control unit 41. Accordingly, in this case as well, the map image displayed on the display 3 is an image indicating the correct orientation in which the offset rotation angle of the upper housing 1 is corrected.

  Further, for example, when only the upper housing 1 is rotated, for example, approximately 180 degrees without moving the lower housing 2 from the opened state of FIG. 6, the geomagnetic sensor 24 inside the lower housing 2 is moved, as shown in FIG. 8. On the other hand, a value indicating an offset rotation angle of 180 degrees is output from the angle sensor 23. In this case, the correction unit 53 corrects the offset rotation angle by 180 degrees. The measured orientation value is sent to the control unit 41. Then, the control unit 41 determines the display orientation of the map image displayed on the display 3 based on the corrected orientation measurement value, so that the map image displayed on the display 3 is as shown in FIG. As shown in FIG. 4, the image shows a correct orientation in which the offset rotation angle of the upper housing 1 is corrected.

  FIGS. 6 to 8 described above illustrate the case where only the upper housing 1 is rotated without moving the lower housing 2. Of course, the mobile phone terminal of the present embodiment uses the upper housing 1. Even when only the lower housing 2 is rotated without moving, or when both the upper housing 1 and the lower housing 2 are rotated, the actual orientation measurement value is corrected by the geomagnetic sensor 24 as described above. be able to.

  As a specific example, FIG. 9 shows a case where only the lower housing 2 is rotated to the left by, for example, approximately 90 degrees without moving the upper housing 1 from the open state of FIG. An example in which the housing 1 has a right offset rotation angle of 90 degrees is shown. As shown in FIG. 9, when only the lower housing 2 is rotated counterclockwise by, for example, approximately 90 degrees without moving the upper housing 1 from the open state of FIG. This azimuth measurement value is an azimuth measurement value indicating that the right side surface of the lower housing 2 is the north azimuth. On the other hand, in the state of FIG. 9, the angle sensor 23 outputs a value indicating the right offset rotation angle 90 degrees. Therefore, in this case, the correction unit 53 only outputs the right offset rotation angle 90 degrees. The corrected azimuth measurement value is sent to the control unit 41. And the control part 41 determines the display azimuth | direction of the map image displayed on the display 3 based on such a corrected azimuth | direction measurement value. Therefore, as shown in FIG. 9, the map image displayed on the display 3 at this time is the offset of the upper casing 1 even though the lower casing 2 is rotated without moving the upper casing 1. The image is directed in the correct direction with the rotation angle corrected.

  Conversely, for example, when only the lower housing 2 is rotated to the right by, for example, approximately 90 degrees without moving the upper housing 1 from the open state of FIG. 6, the orientation measurement value from the geomagnetic sensor 24 inside the lower housing 2 is measured. 9 indicates a value opposite to that in the state of FIG. 9, while a value indicating a left offset rotation angle of 90 degrees is output from the angle sensor 23. In this case, the correction unit 53 outputs a left offset. The azimuth measurement value corrected by the angle of 90 degrees is sent to the control unit 41. Accordingly, in this case as well, the map image displayed on the display 3 is corrected for the offset rotation angle of the upper casing 1 even though the lower casing 2 is rotated without moving the upper casing 1. The image is oriented in the correct direction.

  Further, for example, when only the lower housing 2 is rotated by, for example, approximately 180 degrees without moving the upper housing 1 from the open state of FIG. 6, the geomagnetic sensor 24 inside the lower housing 2 is moved. 6 shows a value opposite to that in the state of FIG. 6, while the angle sensor 23 outputs a value indicating an offset rotation angle of 180 degrees. Therefore, in this case, the correction unit 53 The azimuth measurement value corrected by the offset rotation angle of 180 degrees is sent to the control unit 41. Accordingly, in this case as well, as shown in FIG. 10, the map image displayed on the display 3 is the same as that of the upper casing 1 even though the lower casing 2 is rotated without moving the upper casing 1. The image is directed in the correct direction with the offset rotation angle corrected.

  As described above, the mobile phone terminal of the present embodiment corrects the actual azimuth measurement value detected by the geomagnetic sensor 24 with the output value of the angle sensor 23 provided on the rotary shaft 22 of the rotary hinge mechanism. Accordingly, from the state of FIG. 6, for example, as shown in FIG. 7, when only the upper housing 1 is rotated approximately 90 degrees counterclockwise without moving the lower housing 2, or for example, as shown in FIG. 8, For example, when only the upper housing 1 is rotated without moving the lower housing 2, for example, approximately 180 degrees, or only the lower housing 2 is moved without moving the upper housing 1, for example, as shown in FIG. 9. When it is rotated 90 degrees to the left, for example, as shown in FIG. 10, even if only the lower casing 2 is rotated, for example, approximately 180 degrees without moving the upper casing 1, the map image on the display 3 is displayed. The display orientation of can be adjusted to the actual orientation That. That is, since the display orientation of the map image on the display 3 matches the actual orientation, the user can recognize the correct orientation without being confused. Therefore, the display and operation of the terminal can be performed as the original image. To be able to recognize.

[Other examples]
Note that the above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made according to the design or the like as long as the technical idea according to the present invention is not deviated.

  In the above description, the geomagnetic sensor 24 is used as an example of the terminal state detection sensor 52, and the angle sensor 23 is given as an example of the terminal form detection sensor 54, but the present invention is not limited to this example.

  For example, a gyro sensor is provided as the terminal state detection sensor 52 in the lower housing 2, and the display on the display 3 is scrolled according to the output value of the gyro sensor, that is, the detected value in the tilt direction of the lower housing 2. When the control is performed, the output value of the gyro sensor is corrected by the output of the angle sensor 23, so that the inclination direction of the lower housing 2 is not affected by the relative angle of the upper housing 1 with respect to the lower housing 2. And the scroll direction of the display on the display 3 can be matched.

  Further, for example, an acceleration sensor is provided as the terminal state detection sensor 52 in the lower housing 2, and the display on the display 3 is displayed according to the output value of the acceleration sensor, that is, the detected value in the direction in which the lower housing 2 is swung. In the case of performing control such as scrolling, the output value of the acceleration sensor is corrected by the output of the angle sensor 23, so that the lower housing 2 is not affected by the relative angle of the upper housing 1 with respect to the lower housing 2. It is possible to match the direction in which the symbol is swung with the direction of scrolling the display on the display 3.

  In the present invention, even when a GPS sensor, a temperature sensor, or an illuminance sensor is provided as the terminal state detection sensor 52 provided in the lower housing 2, the output value of these sensors is used as the output of the terminal form detection sensor 54. By correcting accordingly, it is possible to correct the orientation and the open / closed detection of the terminal.

  Furthermore, the present invention can combine a plurality of types of sensors as the terminal state detection sensor 52 and correct the output value of each sensor.

  The present invention can be applied not only to a rotary open type mobile phone terminal as shown in FIGS. 1 to 3, but also to a foldable type mobile phone terminal, and the upper case and the lower case are slid. The present invention can also be applied to a slide-type mobile phone terminal that slides horizontally along a rail, and a mobile phone terminal that includes a so-called nail clip-type hinge mechanism in which a folding mechanism and a rotary hinge mechanism are integrated. That is, in the case of a foldable mobile phone terminal, as the terminal form detection sensor 54, for example, an angle sensor that detects a rotation angle in the vertical direction in the folding hinge mechanism can be cited, and the folded state of the terminal is detected by this angle sensor. Can be reflected in the display content. In the case of a slide-type mobile phone terminal, the terminal form detection sensor 54 can include a slide detection sensor that detects a slide amount. By recognizing the slide amount of the terminal by the slide detection sensor, The slide state can be reflected in the display content. In the case of a nail clipper type mobile phone terminal, an angle sensor for detecting a vertical rotation angle that is a folding direction and a horizontal rotation angle similar to the rotation open type can be exemplified. By recognizing the vertical and horizontal rotation angles of the terminal, the state of the terminal can be reflected in the display content.

  Moreover, although the example which controls the display azimuth | direction of the map image on the display 3 is given in the above-mentioned embodiment, this invention is not limited to this example, For example, the pointer, ball, etc. which are displayed on the display 3 When the predetermined object is moved according to the output of the gyro sensor or the acceleration sensor, the moving direction of the predetermined object is corrected by correcting the output value of the gyro sensor or the acceleration sensor by the output of the angle sensor. The present invention can also be applied to an example of adaptively correcting according to the shape of the terminal.
