Wish they had more technical details instead of breathless marketing. Looks like a gyro mouse, as a ring. Definitely neat, but hardly revolutionary. Gyro mice have been around for years (http://www.amazon.com/s/?field-keywords=gyro%20mouse ); they're rather frustrating to use. The ring doesn't look small enough to wear all day, and the latency looks pretty terrible in the demo video.

What I really want more than another gesture thingy is a one-handed, portable, and eyes-free text entry device; something that could really replace a keyboard for a mobile device, even for demanding activities like programming. Is anyone working on that?

I cant find the product right now but I recently saw a bluetooth chorded keyboard. Unlike the soft keyboards chorded keyboards have the added benefit that you can still maintain typing speed and use proper punctuation.

Speaking of chorded keyboards, see also http://en.wikipedia.org/wiki/Stenotype

I've never used one, but I want to. They're so expensive, though :(

You can get to 40+ wpm pretty easily on a standard iphone. Kids these days have no trouble typing fast, one-handed, on their phone.

As for programming -- a language could be invented that is on-screen keyboard friendly (no brackets, etc).

Or a simpler way instead of implementing a new language -- just use a custom keyboard. Android already has this and iOS 8 just added it.

The question here is eyes-free text entry, portable speed is not really an issue nowadays (typing this on ipad)

Please let us know what technical details you would like (and dont see on our website).

I'd like to see a list of sensors and output devices that it has (from the video I assume it has an accelerometer, gyroscope, 2 buttons, and a touch-sensitive strip, anything else? magnetometer? microphone? light sensor? speaker? vibration motor? LED?), ideally with precision/accuracy, sampling rate, and latency figures. Weight, battery life, wireless range and technology would be nice too.

Ah, after poking around a bit I found wireless range and battery life (though "1 day of active use" isn't very specific). These kinds of specs should be front and center in a list on your developer pages.

github.com/openspatial already documents the wire protocol, has sample code, SDKs for iOS/Android and an emulator.

We invested our time in making sure the SDK was robust and documented well for developers. We plan to add more technical documentation in the future. Stay tuned.
