Now in its second year the Global Impact Challenges ask UK charities to come up with innovative ideas for to solve some of the world's toughest problems by using technology.

From hundreds of entries, 10 finalists were chosen and this week they pitched their ideas to the panel of judges which included Dragon's Den star Peter Jones and Wikipedia founder Jimmy Wales.

The judges picked three of the four winners - including a app for monitoring mosquitos, a network to connect farmers around the world and a system to help keep young people off the street.

The final winner was chosen by a public vote and will see the RNIB's smart glasses project funded to the tune of £500,000 as well as getting the vast experience of Google in trying to develop its new technology.
