Multi Modal Map Annotation Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mapping services often provide inaccurate, vague, or user-unspecific directions that do not account for traffic, weather, or scenic conditions, leading to inefficient navigation.
Innovation Solution
The techniques allow users to modify and annotate mapping instructions on computing devices by adding, deleting, or modifying waypoints, segments, and associated text, images, or audio, enabling more intuitive and condition-specific directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mapping services provide detailed turn-by-turn instructions, then navigation accuracy is improved, but processing loads and bandwidth requirements increase
Solution Approach 1:
The patent segments navigation instructions into discrete annotatable units (waypoints, segments, maneuvers) that can be independently processed and rendered. This allows the system to provide detailed turn-by-turn instructions while breaking down the processing into manageable segments, reducing overall processing loads.
Solution Approach 2:
The patent implements partial annotation where only certain instructions are enhanced with modifications or annotations based on user needs. Not all instructions require full processing detail - the system applies annotations selectively to critical navigation points, reducing bandwidth requirements while maintaining navigation accuracy.
2Measurement precision
If mapping services provide comprehensive navigation instructions, then navigation accuracy is improved, but bandwidth requirements increase
Solution Approach 1:
The patent uses annotation data structures that can be copied and reused across multiple devices and sessions. Once instructions are annotated on one device, the annotations can be copied to other devices, eliminating the need to transmit full instruction sets repeatedly and reducing bandwidth requirements.
Solution Approach 2:
The system transmits only the essential annotation data rather than complete instruction sets. By sending minimal annotation markers that reference stored instruction templates, the system maintains navigation accuracy while significantly reducing bandwidth consumption.
3Adaptability or versatility
If users can modify and annotate instructions, then user-specific customization is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal annotation framework that works across different instruction types (visual, audio, text) and device platforms. The same annotation data structure and modification mechanisms function universally for all navigation instructions, simplifying the user interface despite the versatility of customization options.
Solution Approach 2:
The annotation system is dynamic and adaptive - it adjusts the level of detail and interaction complexity based on user behavior and context. The system learns from user modifications and automatically adjusts annotation prominence and interaction requirements, maintaining ease of use while providing comprehensive customization.

AI summary
Techniques for modifying and presenting instructions for traversing a route include obtaining original instructions and receiving input to modify the instructions. The instructions may be modified and/or annotated based on the input received to provide more intuitive and helpful instructions for traversing a route. The modified instructions may be presented to a user of a computing device as the computing device traverses the route. The modifications and/or annotations to the original instructions may be presented as the computing device traverses the route based at least in part on the location and/or speed of the computing device on the route.
