I've been thinking about this quite a bit from an incremental development point of view.
Mass-marketing would be as hard now as it was originally. Nothing's changed.
There's still a big learning curve for a datahand.
The first phase, to me, has always been to secure a working replacement for existing datahand users.
That's certainly what's driving olddatahands, and others.
Well the case for the existing datahands isn't horrifc, and we all already have one.
So phase 1 feels like it's a "able to replace finger switches and electronics in existing datahands".
Anyone else looking at this form that perspective?
Phase 2 could be a new case. And lots of people want to go straight with a second pointing device, too.
( I think it'd be good. But right now I have a trackpad between the datahands, and it serves me well enough )
However I really don't view wireless + battery as that unattainable.
And if *is* attainable, then it would have an impact on the casing design, right?
Bluetooth 4 obviously lowers the target for how much battery power you'd need,
and arduino's popularity means there's already chips kicking around we can use.
I have a Myo here. If that's able to charge for a short while, and then work for most of a day,
then I think a datahand should be able to too.
Don't know if I've just gone properly pie-in-the-sky with my thinking, but I really feel like
wireless + battery powered datahands in existing case could be a viable phase 2.
And then phase 3 becomes a new package that makes it all smaller and more accessible,
also potentially marketable as a new product.
Just thought I'd share that.
I have a bluetooth 4 chip coming, and I'll run some tests off an 32u4 and a li-on battery.
I have an eye on
http://proto-pic.co.uk/polymer-lithium-ion-battery-400mah/ as a first thought.
