Multi-Device Navigation Session Coordination to Prevent Audio Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiple devices providing navigation instructions to the same destination can cause duplicative and overlapping audio instructions, leading to user confusion and inefficient power and processing usage.
Innovation Solution
Devices detect each other's navigation sessions and interoperate to provide shared navigation instructions, designating one as a primary device to manage communication and audio delivery, optimizing routes based on combined data and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices independently provide navigation instructions to the same destination, then each device can provide navigation guidance, but duplicative instructions and overlapping audio cause user confusion and inefficiency
Solution Approach 1:
The patent merges multiple independent navigation sessions into a single coordinated navigation experience. When a second device detects that a first device is providing navigation instructions to the same destination, the second device suspends its own audio output and displays a notification directing the user to follow the first device's instructions, thereby combining multiple navigation sources into one unified guidance system that eliminates overlapping audio and user confusion
Solution Approach 2:
The patent implements feedback mechanisms where devices monitor and respond to each other's navigation sessions. The second device detects the first device's navigation session through communication links, receives information about the navigation route and instructions, and adjusts its behavior accordingly by suspending audio output and displaying coordinated navigation information, creating a feedback loop that prevents harmful overlapping instructions
2Ease of operation
If multiple devices independently execute navigation sessions, then each device operates autonomously, but power consumption and processing resources are wasted
Solution Approach 1:
The patent enables navigation sessions to serve themselves by having devices automatically detect and coordinate with each other without user intervention. When the second device detects the first device's navigation session, it automatically suspends its own navigation audio and processing, allowing the active navigation session to serve both devices and eliminating redundant power consumption while maintaining autonomous operation at the system level
Solution Approach 2:
The patent implements a mechanism where the second device discards its independent navigation session when it detects the first device's session, recovering processing resources and power. The second device suspends its navigation audio output and route calculation, effectively discarding the redundant navigation function while maintaining the capability to resume independent operation if needed, thereby reducing energy waste
3Loss of information
If devices provide simultaneous navigation instructions, then comprehensive route information is available, but audio overlap makes instructions difficult to hear
Solution Approach 1:
The patent introduces a coordination mechanism as an intermediary between multiple navigation sessions. When the second device detects the first device's navigation session, it acts as a mediator by suspending its own audio output and displaying a notification that directs the user to the first device's instructions, thereby preserving route information availability while eliminating audio overlap that would reduce instruction clarity

AI summary
A first computing device can implement a method for providing navigation instructions. The method includes initiating a first navigation session for providing a first set of navigation instructions to a user from a starting location to a destination location along a first route. The method also includes detecting a second computing device in proximity to the first computing device, and determining that the second computing device is implementing a second navigation session for providing a second set of navigation instructions to the destination location along a second route. Further, the method includes adjusting the first navigation session in accordance with the second navigation session.
