Showing faces to blind people has been a challenge I have been trying to research and resolve for many years. When a face is transferred into a 2D or a 3D form and features are made so that the are enjoyable through a tactile experience, a lot is lost that is still available when looking at a live human, or a photo.
While there are many tactile representations of people, there is much less information about how recognizable those pictures, statues or 3D replicas are.
