A two-way AI-enabled sign language translator designed by teenagers has won a £20,000 technology prize. A team from St Paul’s Girls’ School in London came up with the idea for an intelligent real-time British Sign Language (BSL) translator after they were inspired by the experience of a friend who is deaf. The Amazon Longitude Explorer Prize – for schools across the UK – calls on 11- to 16-year-olds to design, develop and build prototypes of technological solutions for some of the world’s biggest issues to deliver social good. An insect-powered plastic digester, a personal Bluetooth pollution monitor, and a rainforest monitoring station were the ideas of the three runner-up teams who each secured £5,000 for their schools.
