For those who are aurally impaired or who like to watch foreign movies in their original language – which, of course, they don’t understand at all! – a Spanish research team has devised a new little subtitle screen that can be fitted onto a pair of glasses. Based on the same principle as rear-window captioning, this little screen has a 50-meter range and a battery that can let you enjoy the subtitles for up to three hours – not so convenient if you want to watch The Lord Of The Ring in Swahili!
