Peter White talks to Margaret Wilson-Hinds, who with her husband Roger, has designed a new phone application called Georgie. The app enables blind people to navigate their way around, let others know their location and other tasks, using voice-based assistance. Dr Mike Townsend from the British Computer Association of the Blind reviews Georgie. He also talks about a similar product by Synaptec.

And Tony Shearman joins a group of visually-impaired visitors for a guided tour of London's Chelsea Physic Gardens, housing the world's largest collection of medicinal flowers.
