as navigation and information system for blind or partially sighted people

Disclosed is a system and method for use of 'spaces' as navigation and information system for blind or partially sighted people.

In today's world blind people might encounter difficulties to go from point A to point B without external help. The use of 'spaces' coupled with an audio notification device may be used to guide blind people and tell them at any time where they are related to the space they are in. When a source and destination are specified, a space is computed. It's dynamically built based on local configuration (walkways, trails) by specifying accurately the external boundaries. After been built, the geo-location information of the user's mobile device will be used to determine the location of the user related to the space and will provide additional audio information regarding the topology of the 'space'.

The process starts by building a 'space'. One way would be to specify the source and destination using an audio input interface as shown in Figure 1. Then a tool will retrieve the information to determine the route and will build the space based on latitude and longitude information as shown in Figure 2.

After the space is created it is loaded on a server and made available to the user. When a user

wants to go to a specific location, the user activates the space. The geo-location information of the mobile device is processed against the boundaries of the space. An audio alarm tells the user exactly where he stands in...
