I haven’t been experiencing any differences. Been using it for 4+ years.

Yeah, that would make sense!

I love the concept, but could anyone explain to me what the point of a physical robot hand is?

I understand that the children can’t yet read text so they need to see sign language, but what is the point of a physical hand and not a recording of a hand or a CGI hand?

A hand on the screen would:

• be silent
• need no specialized HW
• be cheaper

I can see the novelty of a physical robot hand, but if the point is to help as many children as possible, I don’t see why this is the better option.

Does anyone have more insight into this?

I think you could just store the signatures centrally for validity, no need to store the whole models.

If a task/chore can be done in 2 minutes or less, do it now.

Not sure if it is the best, but it is a simple piece of advice I follow religiously. I think the reason this makes sense is that the cognitive load of trying to remember to do it is higher than just doing it straight away.

Thanks for the info. Signed.
