Your survey is not a survey but a sales pitch.

Not a single question about whether or not I already play chess, at what level, how often, what size, with who, how satisfied I am with my present chess playing technology, what I miss and what I want...

I’ll pass.

Thanks for wasting my time.

Are you targeting individuals who are totally blind or those with some vision?

Chess beginners or serious players?

Have you looked into existing options today, like free smartphone apps for chess that are accessible? A large fraction of blind people are unfortunately unemployed and don't have a lot of money to spend on games, especially when there are cheaper solutions.

Would the software on your chessboard be upgradable? What happens if bugs are found or users request changes?

Does it support timed chess with a chess clock?

If someone loses a piece or breaks it, would they substitute any piece or would they have to special order an expensive one?

Yup, this is just asking us to pick materials and size.

Meh.
