Solution Overview

Problem

Conventional navigation systems face challenges in providing intuitive and safe route guidance, especially in complex environments, due to non-uniform interfaces and the limitations of visual displays, which can be distracting and unsafe for drivers, and audible commands may be confusing in complex situations.

Innovation Solution

The method employs spatial audio cues, including a 'catch' omnidirectional sound, a 'inform' sound with a moving virtual source location, and an 'aid' sound to confirm directions, using three-dimensional audio techniques to provide clear and spatially relevant instructions, enhancing user understanding and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If visual displays of route guidance instructions are used, then route guidance information can be provided to users, but it may not be convenient or safe for users to reference while driving

Engineering Contradiction:

ImprovesafetyVSAvoidroute guidance information delivery

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent replaces visual display mechanisms with auditory output mechanisms. The navigation system uses speakers to provide route guidance instructions through sound rather than visual screens, allowing drivers to receive navigation information without taking their eyes off the road, thereby improving safety while maintaining information delivery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If audible commands are provided for route guidance, then users can receive instructions without visual distraction, but the commands may be confusing or difficult to understand in complex intersections

Engineering Contradiction:

ImprovesafetyVSAvoidunderstandability of navigation instructions

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies local quality by providing spatially differentiated auditory cues. Different sounds are directed to different spatial locations corresponding to different maneuver options or navigation elements. This spatial differentiation helps users distinguish between multiple similar maneuvers in complex intersections, making the audible commands more understandable while maintaining safety.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent adds a spatial dimension to auditory navigation cues. Instead of simple left/right indicators, the system uses three-dimensional spatial audio to position sounds in specific directions and distances, creating a more intuitive understanding of complex navigation scenarios by mapping auditory information to spatial relationships.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Loss of information

If conventional audible commands are used for navigation, then users can receive route guidance without visual distraction, but the commands may be confusing when faced with multiple similar maneuver options

Engineering Contradiction:

AI summary

A method, apparatus, and computer program product are therefore provided for providing a navigation user interface. The apparatus may be caused to: receive an indication of location based information for a user; provide for generation of a first auditory cue, where generation of the first auditory cue may include generating an audio cue having a virtual source location using three-dimensional audio effects. Providing for generation of the first auditory cue may include causing the apparatus to: provide for generation of a beginning of the first auditory cue at a first virtual source location; and provide for generation of a transition phase of the first auditory cue moving the virtual source location from the first virtual source location along a trajectory and ending at a second virtual source location, where the second virtual source location is a location positioned between the user and a location identified in the location based information.
