Solution Overview
Problem
Existing display control devices for mobile terminals, such as those used in golf, face usability issues when the direction of the actual course does not match the direction of the map information displayed, especially when the target is outside the display area or when the map information is enlarged, making it difficult for users to determine the correct orientation and distance to the target.
Innovation Solution
A display control device that displays the angular difference between the direction of the map information and the mobile terminal's direction, using a fixed line indicating the map direction and a variable line showing the mobile terminal's direction, allowing users to intuitively match the map orientation with the actual field, even when the target is outside the display area, and providing real-time distance information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the map information is always shown in a fixed direction on the display, then the control processing is simplified, but the direction of the map information does not match the actual course direction, reducing usability
Solution Approach 1:
The directional information is segmented into two separate visual elements: a fixed line indicating map direction and a variable line indicating terminal direction. This segmentation allows the map to remain in a fixed, easy-to-control state while providing multiple directional references to maintain usability.
Solution Approach 2:
The fixed line and variable line act as intermediaries between the map information and the actual course direction. These lines provide a visual mediation that helps users understand the relationship between map orientation and field orientation without requiring the map itself to rotate.
2Area of stationary object
If the map information is enlarged or the target moves out of the display area, then the display shows more detail or a different view, but the user cannot determine which direction to point the terminal to reach the target
Solution Approach 1:
The variable line provides continuous feedback about the terminal's directional orientation relative to the map. Even when the target is outside the display area or the map is enlarged, the variable line dynamically adjusts to show which direction the terminal is pointing, enabling users to determine the correct orientation to reach the target.
Solution Approach 2:
The patent adds a directional dimension to the display by overlaying the fixed line and variable line on top of the map information. This additional dimensional layer provides orientation context without limiting the map's scaling or panning capabilities.
3Ease of operation
If a directional straight line is displayed to indicate the direction to the target, then the user can match the terminal orientation, but the starting point of the directional icon does not match the current location icon, making it hard to recognize
Solution Approach 1:
The patent merges the directional information (variable line) with the location information by displaying both the current location icon and the variable line originating from the same reference point on the map. This merging ensures that users can clearly associate the directional guidance with their current position, eliminating confusion between location and direction indicators.

AI summary
Provided is a display control device allowing the direction of a map information shown on a display to be correctly recognized even when a target is outside a display area of the display. A display control unit 50 displays on a display 22 of a mobile terminal 10 a map information reproducing a scenery. Further, the display control unit 50 obtains a current location of the mobile terminal 10 from a GPS receiving part 14 as positioning data, thus making it possible to display on top of the map information a coordinate position display section 68 corresponding to the current location of the mobile terminal 10. Here, there are provided a map information display determination section 52 for displaying on the display 22 the map information in a fixed orientation; and an angular difference display determination section 56 for displaying on the display 22 an angular difference between an angle of direction in which the mobile terminal 10 is pointed and an angle of direction of the map information shown on the display 22, every time the angle of direction in which the mobile terminal 10 is pointed is obtained from a direction sensor 16 as direction data.
