A product design firm requested this model. We did not get information on all of its functions but I was told that it is built to help blind people.
We create the accurate shapes of any prototype and are often not given (or required to keep secret) many of the functions of the product itself. We take our clients security very seriously and can only show you images of products that are now public or are not covered under a non-disclosure agreement. Many of our models can never be seen.
