Voice Navigation Feedback for Noisy Turn-by-Turn Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems lack effective interaction with users, particularly in noisy environments, leading to potential misunderstandings and safety risks during turn-by-turn navigation.
Innovation Solution
An interactive voice navigation system that uses audio sensors to analyze user responses, determining context-appropriate audio responses through natural language processing and noise evaluation, allowing for voice interaction without manual input, thereby enhancing navigation clarity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If audio navigation instructions are provided to users, then navigation information delivery is improved, but user understanding may deteriorate in noisy environments
Solution Approach 1:
The system activates audio sensors to capture user responses and analyzes them to determine whether the user understood the navigation instructions. Based on this feedback, the system can determine if reiteration of instructions is needed, creating a closed-loop communication system that adapts to user comprehension levels despite noise interference
Solution Approach 2:
The audio sensor acts as an intermediary between the navigation system and the user, capturing audio data that indicates user understanding. This intermediary allows the system to indirectly assess user comprehension without requiring direct manual input, thereby maintaining navigation flow while improving understanding in noisy environments
2Measurement precision
If manual input is required for navigation interaction, then input accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The system replaces manual mechanical input (typing, button pressing) with voice-based interaction. Users can provide navigation feedback through spoken responses that are captured by audio sensors and processed by the system, eliminating the need for manual input devices while maintaining interaction accuracy
Solution Approach 2:
The system automatically activates audio sensors and processes user responses without requiring users to manually initiate interaction. The navigation system self-manages the audio capture and analysis process, allowing users to simply speak their responses naturally during navigation
Data Source
AI summary
The present disclosure is directed to interactive voice navigation. In particular, a computing system can provide audio information including one or more navigation instructions to a user via a computing system associated with the user. The computing system can activate an audio sensor associated with the computing system. The computing system can collect, using the audio sensor, audio data associated with the user. The computing system can determine, based on the audio data, whether the audio data is associated with one or more navigation instructions. The computing system can, in accordance with a determination that the audio data is associated with one or more navigation instructions, determine a context-appropriate audio response. The computing system can provide the context-appropriate audio response to the user.
