Solution Overview

Problem

Conventional danger avoidance systems often distract users by introducing additional sensory information, which can exacerbate dangerous situations by overwhelming the user with alerts.

Innovation Solution

A system that modifies the audio panorama to focus the user's attention on potential dangers by narrowing and aligning sound sources with the direction of the threat, using techniques such as noise cancellation and spatial compression to create an audio cone that draws the user's perception towards the danger without introducing extraneous sensory input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If additional sensory information is introduced to alert the user to danger, then the user becomes aware of the danger, but the user becomes distracted or overwhelmed and loses focus

Engineering Contradiction:
Improveawareness of dangerVSAvoiduser focus
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system extracts only the critical directional information from the full audio panorama, isolating sounds from specific directions and presenting them in a simplified format that maintains awareness without overwhelming the user with complete environmental audio data

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies different audio processing qualities to different directions - enhancing and clarifying sounds from dangerous directions while attenuating or filtering sounds from safe directions, allowing the user to focus attention on critical threats without processing all ambient sounds equally

Inventive Principle:
Principle #3Local quality

AI summary

A personal safety system detects imminent danger or other event of interest and then modifies a sound panorama to focus a user's attention towards the direction of the danger or other event of interest. The personal safety system may isolate sounds originating from the direction of the danger or other event of interest, collapse the sound panorama towards the direction of the danger or other event of interest, or compress the sound panorama to align with the direction of the danger or other event of interest. The personal safety system may be integrated into an automobile or a wearable system physically attached to the user. Advantageously, the attention of the user may be drawn towards imminent danger or other events of interest without introducing additional sensory information to the user, thereby reducing the likelihood of startling or distracting the user.
