Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems rely on textual messages or audio signals with limited pitch range, failing to effectively convey direction, distance, and angles in three dimensions, leading to inefficiencies and increased energy consumption.
Innovation Solution
Generation of three-dimensional audio effects that simulate sounds coming from specific points in space, utilizing a remote service to offload processing and associating these effects with zones to reduce computational and resource demands, thereby enhancing user navigation efficiency and reducing cognitive load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If three dimensional audio effects are generated to provide descriptive navigation cues, then navigation efficiency and user orientation are improved, but processing power and computational resources are consumed
Solution Approach 1:
The patent extracts the computationally intensive audio processing function from the mobile device and relocates it to a remote server. The server generates three-dimensional audio effects based on navigation data, then transmits only the final audio output to the device for playback. This extraction resolves the contradiction by eliminating local processing power consumption while maintaining navigation efficiency enhancement.
Solution Approach 2:
The patent introduces a remote server as an intermediary between the navigation system and the user's mobile device. This intermediary performs the computationally expensive three-dimensional audio generation, acting as a mediator that offloads processing from the device while delivering enhanced navigation audio cues. The server mediates between the need for complex audio processing and the device's limited resources.
2Measurement precision
If three dimensional audio effects are recalculated frequently to maintain accuracy, then navigation precision is improved, but energy consumption and processor cycles are increased
Solution Approach 1:
The patent extracts the energy-intensive audio recalculation process from the mobile device and transfers it to a remote server. The device only needs to maintain location tracking and communicate with the server, while the server handles all computationally intensive audio regeneration. This resolves the contradiction by maintaining navigation precision through frequent updates without proportionally increasing device energy consumption.
Solution Approach 2:
The remote server operates autonomously to generate and update three-dimensional audio effects based on navigation data received from the device. The server self-manages the computationally intensive tasks of audio synthesis and regeneration, freeing the mobile device from these energy-consuming operations while maintaining continuous navigation precision.
3Measurement precision
If detailed three dimensional audio effects are provided to indicate precise location, then navigation accuracy is improved, but cognitive load on the user is increased
Solution Approach 1:
The patent transforms navigation information from abstract spatial coordinates into intuitive three-dimensional audio parameters. Instead of presenting users with numerical location data or complex directional instructions, the system converts this information into auditory cues with properties such as direction, distance, and elevation encoded in the sound itself. This parameter transformation resolves the contradiction by maintaining precise location indication while reducing cognitive processing requirements through natural human auditory spatial perception.

AI summary
Mechanisms for navigation via three dimensional audio effects are described. A current location of a device and a first point of interest are determined. The point of interest may be determined based on a web service and the current location of the device may be determined via mobile device signals. A zone that includes the point of interest may be determined. A three dimensional audio effect that simulates a sound being emitted from the zone may be generated. The three dimensional audio effect may be transmitted to speakers capable of simulating three dimensional audio effects. The transmitted three dimensional audio effect may aid in navigation from a current location to the point of interest.
