Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional methods for setting waypoints on electronic maps for unmanned vehicles are inefficient, requiring repetitive pinch-to-zoom actions, leading to accuracy issues and unnecessary time waste, especially when trying to center arbitrary points on the display.

Innovation Solution

A method that allows continuous touch input for selecting and adjusting waypoints on an electronic map, using magnification change regions to expand or contract the map while maintaining touch, and switching to a movement mode for precise point setting, reducing the need for repeated touch inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional pinch-to-zoom actions are used to select waypoints on the map, then the user can change map magnification, but the process requires repetitive actions and causes time waste

Engineering Contradiction:

Improvewaypoint selection accuracyVSAvoidtime for setting waypoints

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system automatically centers the map on the selected point before magnification adjustment, preparing the optimal view in advance. This preliminary centering action eliminates the need for users to manually re-center the map after zooming, reducing repetitive operations and time waste in waypoint selection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The touch input is continuously maintained during the entire process of sensing point selection, receiving magnification commands, and sensing icon movement. This continuous touch state allows seamless transition between map magnification adjustment and waypoint selection without requiring the user to release and re-acquire the touch state, eliminating interruptions and reducing time waste

Inventive Principle:

Principle #20Continuity of useful action

2Area of stationary object

If the map is expanded when an arbitrary point is not at the center, then the point may deviate from display, but the user can see more of the surrounding area

Engineering Contradiction:

Improvevisible map areaVSAvoidpoint selection accuracy

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The system automatically centers the map on the selected point before executing magnification adjustment. This preliminary centering ensures that the point remains within the display area during expansion, maintaining selection accuracy while still allowing the user to see the surrounding area. The map is re-centered dynamically to prevent point deviation even as the view expands

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the position of the selected point relative to the display boundaries during magnification adjustment. When the point approaches the display edge, the system provides feedback by automatically adjusting the center position to keep the point visible, ensuring both expanded view and accurate point selection are maintained

Inventive Principle:

Principle #23Feedback

3Measurement precision

If conventional map expansion is used, then the user can see details better, but the pinch-to-zoom action must be repeated multiple times

Engineering Contradiction:

Improvepoint selection accuracyVSAvoidoperational simplicity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The magnification adjustment is executed continuously while the touch state is maintained, rather than requiring discrete pinch-to-zoom gestures. The system processes the magnification command and adjusts the map in one continuous operation, eliminating the need for repeated pinch-to-zoom actions and simplifying the user interaction while maintaining precision

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system prepares the optimal magnification level and center position in advance based on the selected point, then executes the adjustment in a single smooth operation. This preliminary preparation eliminates the need for multiple trial zoom actions, making the operation simpler while achieving the desired precision in one step

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for setting a target point on an electronic map, the method performed by an electronic apparatus equipped with a display on which the electronic map is displayed and commands are input through touch, the method may include: sensing a selection of one point on the electronic map; displaying a selection icon on the electronic map; receiving an input of a magnification change command of the electronic map through a first touch; and adjusting the electronic map by expanding or contracting the electronic map with respect to the one point in accordance with the magnification change command and displaying the electronic map on the display, wherein at least the first touch may be continuously maintained during the sensing of the selection of the one point and the receiving of the input of the magnification change command.
