Description

  The present invention relates to a screen display device, a screen display method, and a program.

  In recent years, various proposals have been made with the progress of disaster prevention related technologies. As one of them, an alarm system that promptly detects the occurrence of an earthquake and informs the arrival time by voice or text information has been proposed. It collects information from seismometers installed at each observation point by a monitoring server, calculates the epicenter and magnitude (magnitude) at the same time as the occurrence of the earthquake, and it is a television station, radio station, each office, each home, etc. Is transmitted to an alarm device, radio, or television receiver installed in the earthquake, and data relating to the earthquake arrival time (several seconds to several tens of seconds) and seismic intensity is transmitted, or an alarm device alerts. In recent years, the number of observation points has increased in order to increase the accuracy of alarms. In observation point management, it has become essential to select an observation point at the same point as a point on the map for maintenance. If the display is overlapped even in a place where the observation point density is high, a phenomenon occurs in which reading is not possible or selection is not possible.

  The system includes selection means for accessing information at a location on the map. It is not always necessary to indicate the exact location on the map, but it can be used when it is necessary to read and select the display reliably.

The alarm analysis calculation and analysis device includes an operation unit and a display unit. A map is displayed on the display unit. When the cursor on the map is clicked, the position information and earthquake information of observation points are displayed on the map as character strings. It is displayed.
A related technique for displaying a character string on a map in this way is disclosed in Patent Document 1.
This "character string output device" is arranged along the line segment designating means for designating an arbitrary line segment pattern among the line segment patterns constituting the figure, and the line segment pattern designated by the line segment designating means. A character string designating unit for designating a character string to be specified; an angle calculating unit for calculating an angle of a line segment pattern designated by the line segment designating unit; and a character string designated by the character string designating unit as the angle calculating unit. Output means for arranging and outputting along the angular direction calculated by the above.
According to this character string output device, when an arbitrary line segment pattern is specified by the line segment specifying unit, the angle calculating unit calculates the angle of the line segment pattern specified by the line segment specifying unit. Then, the output means arranges and outputs the character string designated by the character string designation means along the angle direction calculated by the angle calculation means. Therefore, when a figure and a character string are mixedly input, the character string can be arranged in a well-balanced manner along an arbitrary line segment constituting the figure.

By the way, there are many earthquake observation points nationwide, and in many cases, there are many earthquake monitoring devices of the Japan Meteorological Agency and private earthquake monitoring devices at the same point. For this reason, a plurality of character strings may overlap when an observation point on the display unit of the calculation analyzer is clicked.
However, in the technique described in Patent Document 1 described above, there is no mention of superimposition of character strings although the character strings are tilted or reduced.
If the map is reduced too much, more observation points should be selected, and if the map is enlarged too much, character strings overlap.

FIG. 4 is an example of a virtual screen used in the screen display device shown in FIG.

First, a map (in this case, the Kanto region is not limited) is displayed on the display means 5.
The control unit 7 determines whether or not there is a click. That is, it is in a standby state (FIG. 1: step S1).
When an operator (not shown) operates, for example, a mouse as the input unit 6 to move the cursor on the real screen to a desired position and left-clicks, the control unit 7 determines that there is a click (FIG. 1: step). S1 / YES), it is determined whether or not there is a displayed character string at the click position. The presence / absence of a displayed character string is determined based on the presence / absence of a block on the virtual screen (step S2).
When it is determined that there is no displayed character string at the click position (step S2 / NO), the character string is entered in the display means 5 (step S7), and the position of the displayed character string on the virtual screen is displayed. The block is filled (step S4).

When the control unit 7 determines that there is a displayed character string at the click position on the real screen (step S2 / YES), the control unit 7 displays the character string adjacent (shifted) to the displayed character string (step S2). S3).
At this time, information such as the latitude, longitude, observation point name, and seismic intensity of the observation point at the clicked position is displayed on the display unit as a character string.
For example, as shown in FIG. 4, the “tree” portion of the two characters “Tochigi” is filled with blocks of four characters. This means that the first two character blocks are filled, and the second two lower character blocks are filled.
As a result, when a plurality of observation points are concentrated or overlapped at the clicked position, they are displayed shifted (adjacent) from the displayed character string. In addition, although the mark of an observation point and a character string are displayed on a display part, an observation point is displayed so that it may be located in the same block.

  The control unit determines whether or not the click has ended, that is, waits (step S5). If there is a click again (step S5 / NO), the control unit returns to step S1 and ends (end operation by keyboard operation). If so (step S5 / YES), the paint is deleted (step S6) and the process ends.
