I remember seeing one of the original Datahands as a child and wanting to try it, but never got the chance. I'd love to get one of these if they become available! Currently working on making an Ergodox.

Hey guys, it's almost a year since your last activity, is the work still going? There're plenty of fancy new keyboards on the market but none of them beats the DodoHand's potential. If you need any kind of help to keep it going just tell me.

I hate registering on forums but rediscovering the DataHand again, while reading about the split keyboards made me do it. The split keyboards I see people getting so excited about just seem like a rehash of an old idea. Those DataHand people thought outside the box, but were too far ahead of their time unfortunately.   :(

If 3D printing doesn't work yet, how about using traditional molds for the keys? Ask a factory in China to make them out of aluminium. Or get a local old school metal worker to make them. :)

I've made more progress on my work for an ergonomic HID. However I can't promise when i'll be done, I went deep with this one, deep into the rabbit hole haha
Will use optimization throughout development with humans in the loop, and re-evaluation from new simulations, 3d print improved version :)

To setup biomechanical simulations with parametric model generation takes a lot of time. Does anyone know if Datahand development used biomechanical simulation for development?

Below is the 3d printer I bought that has missing parts so I'm making my own in laser cut steel cnc-milled aluminum.
When that's done I can start making HIDs!

I'm guessing they did not. If they had done it then how did they justify switches on sides (left/right) of fingers. Try to move e.g. your ring finger left/right without moving other fingers.

Hm, I might be an odd duck, or perhaps well trained from 10+ years on datahand, but I can move ring fingers that way without any problem. Otherwise it'd be major pain to "type" Esc,B,N,Win keys. :-)

(and I do have almost all hotkeys mapped as Win-<something>, so, yeah, works for me just fine)

You could ask the inventor himself maybe, but he is getting up there in years. I saw a webpage with Dale Retter's address on LinkedIn but I can't find it. Leland Knight a mechanical engineer helped him make it.

I was thinking about how technology is getting smaller and was wondering if a wearable could replace the DataHand. So I went looking and found this yesterday, but as usual with anything really interesting they have given up. They reached their goal on Kickstarter then gave all the money back, because they needed additional funding that fell through.

A system where sensors on your wrist report the vectors to your fingers. That way you could build a DataHand without any moving parts. Everything else would be code.

Edit:
Well it looks like it is already here.

Edit 2:
Actually I was just thinking about the risks associated with wearables, in that they put electric fields next to your flesh. It could be a cancer risk. They say the same of mobile phones.

I have Dale Retter's email (not that hard to find in Google), but was unable to get him on the phone; he's all promise & no follow through.

PM if you want the email.

Then there's also https://www.tapwithus.com/product-2/ (or maybe better link would be https://www.tapwithus.com/overview/ ). Which looks promising, but still somewhat off the mark.

I accidentally also saw someone (on Kickstarter?) create a Kinesis-like keyboard that is split to two units (DH style) where one of the units as a whole also functions as [an oversized] mouse, but can't really remember the link. It would be a neat idea to integrate that into dodohand. :-)

That looks interesting. If it was two handed I would be very tempted. It might be good for kicking back and surfing though.

I had a look at that one, but I thought moving the keyboard out of position might give you shoulder and back problems. However there is a comment on their Kickstarter, where they said they wanted to make a version with a trackball. That could work. But the DataHand looks way cooler... ;)
