Description

  The present invention relates to a portable map display device and a program capable of easily changing the scale of a display map and scrolling.

  In recent years, portable navigation devices have become widespread along with in-vehicle navigation devices. These navigation devices are provided with an input device for changing the scale of the map screen and for scrolling operation by touching the screen or using a pointer such as a button, lever or mouse.

  Conventionally proposed input devices for changing the scale of a map screen and scrolling operation need to remember and use a plurality of button operations in order to perform the operation, which is not always sufficient in terms of operability.

An object of the present invention is to solve the above-described problems, and an object of the present invention is to enable an intuitive operation by minimizing an input operation.
The present invention provides a detection means for detecting a linear movement operation or an inclination operation, a scale change processing means for changing the scale of a map to be displayed based on a detection result by the detection means, and a map based on the changed scale. And display means for displaying.
The present invention also includes a step of detecting a linear movement operation or a tilt operation, a step of changing a scale of a map to be displayed based on a detection result in the detection step, and a step of displaying a map based on the changed scale. It features a program to be executed by a computer.

  Since the present invention detects an operation of moving the portable map display device and changes the scale, an intuitive operation can be realized, and the operability can be greatly improved.

Embodiments of the present invention will be described below.
FIG. 1 is a block diagram showing a configuration of a portable map display device according to the present embodiment.
The main body 1 of the portable map display device is a microcomputer that performs processing for reading the map data 2 held and displaying the map data 2 on the display 3. The scale change processing unit 1a for changing the scale of the map to be displayed, the display of the map It has a display processing unit 1b that performs processing. The sensor 4 is a commercially available MEMS (Micro Electro Mechanical System) sensor that uses a semiconductor process to produce an acceleration detection mechanism such as a resistance type, a capacitance type, or a heat detection type. For example, a linear motion is achieved by using a three-axis acceleration sensor. And the posture can be detected. In addition, sensors such as a strain gauge type, a piezoelectric acceleration sensor, and a gyrocompass can be used. In the present embodiment, the sensor 1 detects an operation of linearly moving and tilting the map display device, and determines a scale displayed by the scale change processing unit 1a according to the detected operation amount. The scale may be determined by, for example, preparing a conversion table indicating the correspondence between the operation amount and the scale and referring to this table. In this way, the display processing unit 1b outputs the determined scale map to the display. The operation for increasing the scale ratio and the operation for decreasing the scale ratio may be performed by determining the operation direction.

FIG. 2 is a diagram illustrating an example of an operation detected by a sensor.
The map display device 10 has a display screen 11 on the front surface. For example, an operation in the left-right direction (horizontal direction parallel to the screen) (FIG. 2A) and an up-down direction (vertical direction parallel to the screen) are performed. When a linear movement operation such as (FIG. 2B), a left-right tilt operation (FIG. 2C), or a front-back tilt operation is detected, this operation is detected by the sensor 1, and the detected operation The scale is changed according to the amount. Note that the linear moving operation and the tilting operation are not limited to this, and may be an oblique moving operation and a tilting operation.

FIG. 3 is a block diagram showing a configuration of an embodiment in which switching between scale change and screen scroll is performed, and FIG. 4 is an explanatory diagram of switching between scale change and screen scroll.
In this embodiment, the configuration shown in FIG. 1 further includes a screen scroll processing unit 1c, a switching control unit 1d, and an input device 5. As described above, when an operation for linearly moving or tilting the apparatus is detected by the sensor 1, the scale change processing unit 1a determines a scale corresponding to the detected operation amount. Further, in the present embodiment, the screen is scrolled by the scroll processing unit 1c according to the detected operation amount. In this case as well, a conversion table indicating the relationship between the operation amount and the scroll amount may be prepared, and scrolling may be performed by referring to this table. Moreover, you may scroll a map in the direction according to the operation direction. The scale change process and the scroll process are switched by the switching control unit 1d. That is, as shown in FIG. 4, the scale change process and the scroll process are switched by the operation of the input device 5 (for example, the operation button at the bottom of the screen shown in FIG. 2).

  The present invention is not limited to the above example, and various modifications are possible. For example, in a scale change according to the amount of linear operation or tilt operation, a separate operation button is provided, and the scale change process is performed when a linear move operation or tilt operation is performed while this button is pressed. When the operation button is released, the operation button may be fixed to the scale before the release or may be fixed to the scale at the start of the operation. In addition, in the scroll process, the scroll process is performed when a linear movement operation or tilt operation is performed while the separately provided operation button is pressed, and when the operation button is released, the map is displayed at the position before the release. May be fixed, or may return to the operation start position (current location, etc.).

It is a block diagram which shows the structure of the portable map display apparatus of this embodiment. It is a figure explaining the example of operation detected with a sensor. It is a block diagram explaining the example which switched the scale change and screen scroll. It is explanatory drawing of the change of a scale change and screen scroll.
