There was a product very similar to this in the late 1980s. My uncle invested in the company. But it flopped. I am sorry I cannot remember the name. I do remember skilled typists could use it at least as fast as 2 hand traditional typing.

Wasn't the Microwriter was it perchance?

I saw that demoed at Notts Micro Computing Club in the early 80s. IIRC a Microwriter was used to drive input for an Acorn Electron.

[medwards666]

Yup. There were drivers for both the Electron and the BBC Micro (required the Model B IIRC, Model A didn't have enough spare RAM for the software)

That tracks. I just don't think there's the sales volume you'd need to manufacture and sell something like this at an adequate profit, and certainly in the 80s it would have been even more difficult to find enough compute and utility in one place without the benefit of Internet services.
