Nav Devices Guide Blind Using New Smartphone Technology

Those with ailing sight could soon benefit from improved navigation thanks to new smartphone technology which has been developed by Fujitsu and Japan's National Institute of Information and Communications Technology (NICT).
Real-time positioning data is generated by the system which uses ultra wide band (UWB) technology within a smartphone device to enable navigation within buildings.
This is a major development on existing GPS systems which are unable to transmit signals within walls, thus restricting their services to larger-scale external navigation.
According to reports, this newly developed system is capable of pinpointing locations with an accuracy of less than several tens of centimetres and uses radio-wave technology to measure distances. When implemented into devices, such as smartphones, this allows precise directions to be delivered to the user; navigating them around buildings with ease.
The current system adopted by Fujitsu and NICT saw the technology turned towards aiding those with partial or no sight navigate otherwise problematic routes.
They intend to demonstrate the system at the upcoming Wireless Technology Park 2012 (taking place July 5-6) before furthering developing the technology into a navigational device capable of detecting obstacles on the road.
Of course, this is not the only time that more accurate, internal navigation has been the focus of development. In May of this year an indoor satnav was developed to aid shoppers after receiving investment from the German government.
