• Assistive Technology

  • Support for Deaf Children

    • Most adults in a child's life do not learn how to sign

    • While baby sign is commonly learned these days, adults tend to look for the perfect sign

    • Toddlers mispronounce words as they learn to speak, they also lack the fine motor skills for distinct signs

    • How does a caregiver know what the child wants?

    • There is not a large dataset of young children signing which limits machine learning techniques

    • Currently experimenting with different machine learning algorithms to see if the caregiver takes a photo of the child, a list of possible words could created

    • Research problems 

      • Some signs can be very similar

      • Facial expressions can change a sign

      • Context of sign matters
