Reach-Probability Map Labels for EV Driving Range Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying the driving range of an electric mover on a map can confuse users, as they often resemble road or border lines, making it difficult to distinguish the driving range from other map features.
Innovation Solution
An information processing method that acquires input data including the current location, background map, and reach probabilities to change the display manner of location names based on these probabilities, superimposing characters on the map to clearly differentiate the driving range, with options such as varying character size, color, and priority display for high or low reach probabilities, and landmark locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driving range is represented by an outline of a polygonal graphic obtained by drawing a line on the map image, then the driving range can be displayed on the map, but the display may confuse the user as it resembles road or border lines
Solution Approach 1:
The patent applies local quality by changing the display characteristics of location names based on their reach probability. Location names with different reach probabilities are displayed with different visual properties (such as font weight, size, or color intensity), allowing users to intuitively understand the driving range without confusion. This resolves the contradiction by providing clear driving range information through differentiated local display qualities rather than uniform polygonal outlines.
Solution Approach 2:
The patent changes display parameters of location names according to reach probability values. By dynamically adjusting visual parameters (font size, weight, color) based on the calculated reach probability, the system provides intuitive driving range information that distinguishes itself from static map features like roads and borders, thereby eliminating user confusion while preserving information clarity.
2Loss of information
If location names are displayed uniformly on the map, then all locations are shown, but users cannot intuitively understand the driving range
Solution Approach 1:
The patent applies local quality by making different parts of the display (location names) have different visual properties based on their reach probability. This allows the system to convey driving range information intuitively through differentiated display characteristics while still showing all location names, thus resolving the contradiction between providing intuitive understanding and displaying all locations.
Solution Approach 2:
The patent uses partial action by applying enhanced display treatment only to location names that fall within the driving range, while displaying other location names in a standard manner. This selective differentiation provides intuitive driving range understanding without requiring changes to the entire map display or omitting any location names.

AI summary
An information processing method includes: acquiring input data including a current location of an electric mover, a background map indicative of a region around the current location, a location list including a register of names of a plurality of locations, and a reach probability from the current location to each of the locations included in the location list; changing a display manner of a character indicative of the name of each of the locations according to the reach probabilities; and outputting a superimposed map obtained by superimposing the character indicative of the name of each of the locations in the display manner on the background map.
