Invented by a 25-year-old electronics engineer from Kenya, Sign-IO is a smart glove that converts sign language movements into audio speech. Roy Allela’s invention is to help children with speech and hearing impediments. According to a report by The Guardian, the gloves have “flex sensors stitched on to each finger. The sensors quantify the bend of the fingers and process the letter being signed. The gloves are paired via Bluetooth to a mobile phone application that Allela also developed, which then vocalises the letters.” Allela’s goal is to place at least two pairs of the award-winning gloves in every special needs school in Kenya.
