Video: Microsoft develops smart headset to help blind people navigate

Microsoft has partnered with charity Guide Dogs to develop a new smart headset that creates a 3D sound map to help visually impaired people navigate better as well as discover more of the world around them. Built into an existing piece of head wear that conducts sound through the jaw bone rather than covering the ears, Microsoft's 3D audio technology - as the firm calls it - delivers direction-based sound so that wearers not only know when they are approaching a point of interest, but also in which direction it is.
