Roy Allela’s Sign-IO Gloves: Communication Gap for the Deaf

Roy Allela, a 25-year-old engineer from Kenya, has made a groundbreaking contribution to the deaf community with his invention of the Sign-IO gloves. These innovative gloves translate sign language gestures into spoken words, facilitating communication between deaf individuals and those who do not understand sign language. The Sign-IO gloves are equipped with sensors on each finger, which detect the movements and positions of the fingers. These sensors connect to an Android phone via Bluetooth. The phone, in turn, uses an app that translates the hand movements into spoken words, making it possible for deaf individuals to communicate more easily with others.

The inspiration for the Sign-IO gloves came from Allela’s personal experience with his six-year-old niece, who was born deaf. The family often struggled to communicate with her due to their lack of knowledge of sign language. This personal challenge drove Allela to create a solution that would help not just his niece, but potentially millions of deaf individuals worldwide.

Allela first gained widespread recognition in 2019, when he introduced the Sign-IO gloves to the public. The gloves, named for their ability to translate sign language into input-output (IO), underwent rigorous testing at a school for deaf children in Migori County, Southwest Kenya. Feedback from these young users was instrumental in refining the gloves’ design and functionality. The gloves are designed to be user-friendly and appealing to children, featuring customizable designs with popular characters. This thoughtful design consideration ensures that the gloves are not only functional but also attractive to young users, encouraging their use and acceptance.

The Sign-IO system is particularly tailored to the needs of young children with hearing and speech impediments. The embedded hardware reads the finger movements and compares them to an internal database of American Sign Language gestures. The corresponding words are then spoken aloud by the mobile app. Users have the flexibility to customize the voice output, adjusting parameters such as gender, pitch, tempo, and delay to suit their preferences.

Roy Allela’s vision extends far beyond his family. He hopes that the Sign-IO gloves will benefit the approximately 34 million children around the world who are deaf, providing them with a tool that enhances their ability to communicate and integrate more fully into society. His innovative work not only addresses a critical communication barrier but also inspires future advancements in assistive technology.

Roy Allela’s Sign-IO smart gloves have gained significant recognition for their impact on the lives of individuals with speech impediments. Allela was shortlisted for the prestigious 2019 Africa Prize by the Royal Academy of Engineering. Additionally, his innovative gloves earned the Hardware Trailblazer award at the 2017 ASME Innovation Showcase (ISHOW) competition. Allela planed to use the prize money to enhance the accuracy of vocal predictions, further advancing his transformative technology.
