Conversational Narrative Navigation via Landmark Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems provide limited intuitive guidance, often relying on linear instructions that may confuse users regarding orientation and turns, especially in unfamiliar environments, and face challenges in translating human conversational narratives into comprehensible navigation data.
Innovation Solution
A system that converts conversational narratives, including spoken language and gestures, into navigable data by using processors and memory to identify navigation elements, correlate them with geographic databases, and present intuitive route guidance, accommodating language and cultural differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If linear turn-by-turn instructions are used for navigation guidance, then the system is simple to implement, but users get confused regarding orientation and turns in unfamiliar environments
Solution Approach 1:
The patent introduces landmarks as intermediary reference points between the user and the navigation instructions. These landmarks (buildings, monuments, natural features) serve as mediators that help users orient themselves and understand their position relative to the route, transforming abstract directional commands into concrete, visually recognizable cues that bridge the gap between simple instructions and comprehensive navigation assistance
Solution Approach 2:
The patent adds a spatial and contextual dimension to navigation guidance by incorporating environmental features and landmarks into the instruction set. Instead of purely linear directional commands, the system provides multi-dimensional guidance that includes visual references to surrounding objects, creating a richer navigational context that helps users maintain orientation without significantly increasing system complexity
2Reliability
If natural guidance with environmental context is provided, then user orientation and understanding improve, but the system complexity increases due to processing conversational narratives and correlating with geographic databases
Solution Approach 1:
The patent implements a multi-functional processing system that handles diverse input types (spoken language, gestures, text) through a unified conversational narrative analysis framework. The same processor architecture correlates multiple data sources (landmark databases, geographic information, route data) using integrated algorithms, allowing the system to perform multiple navigation tasks through a single versatile processing platform rather than separate specialized systems
Solution Approach 2:
The patent creates simplified digital representations (copies) of real-world landmarks and environmental features within the geographic database. These digital copies contain essential identifying characteristics that enable pattern recognition and correlation with sensor data, allowing the system to process complex environmental information through streamlined data structures that reduce computational complexity while maintaining navigation accuracy
3Loss of information
If landmark information is integrated into navigation instructions, then contextual understanding and ease of following directions improve, but data collection and processing requirements increase
Solution Approach 1:
The patent performs preliminary data collection and organization of landmark information during database creation and maintenance phases. Landmarks, their characteristics, and spatial relationships are pre-processed and stored in optimized data structures before navigation use. This preliminary action allows the system to retrieve and utilize rich contextual information during actual navigation without requiring complex real-time data collection and processing
Data Source
AI summary
The disclosed embodiments relate to recognition of navigation and/or guidance related information within an expressed conversational narrative between a provider of the narrative and a receiver thereof. The recognized navigation and/or guidance related information is then converted into navigation data which may be used to present a navigation route and/or guidance information related thereto to the receiver.
