The Most Promising Application Idea

The Most Promising EGNOS Application Idea

WHAT ?acoustic binaural + GNSS =

guidance people among the pre-defined track

FOR WHOM?blind, partially sighted

people, people working in environments with low

visibility

HOW ?spatial paths could be

represented as a sequence of acoustic cues


Technical description

The sequence of the bell rings allows any person to build a mental map of the path.

Although the sound is the same it is perceived in a different way depending on the distance and orientation

User Direction

Absolute positioning

Relative positioning

Considering position and orientation of the user the next track points are converted into binaural acoustic cues allowing the user to perceive the position and shape of the track.

The track can be considered as a route compound by a discrete set of geo-referenced waypoints. GNSS is used to calculate user position.

A spatial path can be represented as a sequence of acoustic cues

Key Problems & Solutions

Integrity of position determination →

EGNOS/EDAS

Poor visibility conditions→

GNSS + binaural technologies

GNSS Relevance

Application for personal navigation: GNSS signal required

System uses available GPS and sensors of

the Smartphone

EGNOS implementation:

based on the integration of the

EGNOS SDK

EGNOS for integrity parameters calculation

Optional use of powerful external navigation units

BACK UP SLIDES



Visual impaired people require guidance support in outdoor activities.

Emergency & Rescue teams require guidance assistance in no visibility conditions

Neither research, patents nor products have solved the problem of giving a non- visual track perception.



Track perception would allow blind people to imagine the geometry of he path and walk along it autonomously.

Binaural sounds create the illusion that sounds produced by a stereo headphone emanate from specific directions and distances.

The sequence of the bell rings allows any person to build a mental map of the path.


3SOUND NAVIGATION provides an innovative guidance support system for visual impaired people or in low visibility conditions, based on the provision of a track line perception trough the use of GNSS and binaural sound technologies.
