I've been invited to give feedback to all Parsons students, regarding your thesis projects.
Great idea to find a design concept to link deaf children with hearing peers. It's very important to enhance communication in every way possible between those who have a full range of senses and those who do not. Especially at a young age.
I wonder, however, how this puzzle has unique benefits? What exactly does it do different from other tools available right now?
It's very unclear just by looking at your image attached what the puzzle is meant to do. Is it meant to simply introduce sign language among hearing and deaf children? If so, how does it do this exactly? Can you give more detailed description about this game as a learning tool?
Your intention is admirable. Push it further and think of how to describe how it might be developed and distributed among nursery or elementary schools nation-wide.
Thanks, and good luck! J.
