To develop a GNSS-based mobility service for people with impaired
visually capabilities, to guide them along a pre acoustic and audio-
haptic signals, which meets the level of accuracy and reliability they
need in urban environment for improving their day life autonomy
Other outcomes:
• Develop innovative tools which could help blind and visually impaired
people to move around autonomously
• Implemenation of a user-friendly portable satellite with acoustic and
haptic user interfaces enabling users to obtain a insight of their
surrounding environment
• Retrieve benefits from navigation services to accuracy and reliability as
well as the level of service availability.

What are binaural sounds?Binaural technologies reproduce the(arrival time and amplitude between the ears).
Binaural sounds create the illusion that soundsby a stereo headphone emanate from specific directionsand distances in the surrounding space.

An intelligent guiding portable device to support people with visual disabilities
as well as other collectives such as people working in low visibility and
hazardous situations or the ageing population.
To build up a pre-commercial navigation product secure, pre-defined track. The
positioning component will use satellite based positioning.
Development of innovative tactile signals, acoustic and audio providing a non-
visual track perception and mental map of the path.
Provide updated data through a public Service Platform on the web.
collected by Argus users will be shared with other ARGUS users or with
general public.
Develop a Personal User Software application this software, stored pre-defined
tracks can be transmitted to the user terminal on demand.

The ARGUS project provides interesting insights to planning as for:
1.the end user involvement
2.the cartographic and semantic aspects
3.the definition of Points of Interest
4.the accessibility of the spaces in the city.
Argus is important also for Municipalities to improve their accessible routes.

Hypothesis: How 3d sound audio-guides can help improve city’s accessibilityKeywords: audio-guide for visually impaired, 3d sounds, accessible citiesSummary: Almost 300 million people in the world are visually impaired. About 90% of the world's visually impaired live in developing countries, and about 65 % are aged 50 and older, with an increasing elderly population in many countries, more people will be at risk of age-related visual impairment.The global response to prevention of blindness have had specify results in areas of progress over the last 20 years including prevention, eye care services, development of policies and strategies, campaigns to raise awareness, and stronger international partnerships with engagement of the private sector and civil society. But this global response have also had one of the main areas of progress on the development and implementation of technical assistance to the users. Despite the technology state of the art many questions remain open concerning autonomous navigation, accuracy, integrity.
