Patent pending kind? I doubt they are sharing it quite yet but the one beauty of patents is we'll get the entire answer once the patent isn't pending anymore. If I had to imagine though, the algorithm is just accounting for the most likely word to follow the previous wording, that could have been formed by hitting keys that were next to the ones you really hit wrong.

This is pretty much how the stock Android keyboard works. It's been able to spot missed keys since at least Ice Cream Sandwich - e.g. I just typed "kettrt" and it's suggesting "letter" as a correction. Since Jelly Bean it's also had some bigram support too (guesses the next word based on the previous without you typing anything). Aside from the "typing without a keyboard" part, it's not obvious from the video how Fle…

But does Android use context clues? iOS can't quite handle the two-letter distance, but it accurately corrects "kryywt" (kryuwt is too far away) without any context.

To me this just seems like lipstick on a pig. I can type really fast on my Motorola Pro+ (it's like an e63 running android!) and not relying on autocorrect means I can do things like type unix commands and control vim.

For the blind - what is the advantage of a phone with a giant battery sucking screen on it in the first place?

Yes, the world is a big and poor place. But in the United States where (like other developed nations of course) people have the financial means to choose, the majority of phones sold are smartphones. And T9 is generally looked at like rotary dial.

Rubbish. Going back to September 2011 as I can't find any newer stats: http://blog.nielsen.com/nielsenwire/online_mobile/40-percent...

Plenty of feature phones have qwerty keyboards, including the one I used up until a few months ago. They're not all T9. Anecdotally, many of my friends have feature phones with qwerty keyboards...

This kind of technology has been around forever, but my guess is that the quality increase here is due to one or both of these two factors:

1) Computing a two-dimensional vector for each word typed, and calculating MSE against the ideal vectors for dictionary words, instead of just comparing the distance of the keys you hit to the locations of keys for dictionary words.

2) Using LSM (latent semantic mapping) to discover context and increase accuracy of #1.

This… this looks and acts almost EXACTLY like the stock Android keyboard. The swipes to accept a correction and to delete a word are new, and the graphic design of the keyboard is more minimalist - but the core functionality of "spellchecks based on words you could spell with keys near the ones you actually hit" and "shows autocorrect candidates in a horizontal row above the keys" is absolutely identical. It's a sham…

I don't think the similarity to the stock Android keyboard is coincidental. The authors of this previously made Blindtype which was purchased by Google.

Hope they hired a good lawyer to review the IP transfer agreements they signed in the previous sale.

Can anyone explain how this works? Seems like total black magic to me... the dude is typing random gibberish and it still figures out the word? Then he's just tapping randomly on the screen, gibberish comes out, then turns into the word he wanted? Don't mean this to sound unintelligent, the video was just crazy. What kind of key proximity algorithms are behind this?

It might be an application of forward error correction, using the redundancy inherent in written English. Instead of interpreting pressing the 'F' key as the letter 'F' with 100% probability, one could interpret pressing 'F' as meaning a 60% probability of 'F' and 5% probability for each of 'E', 'D', 'C', 'V', 'B', 'G', 'T', 'R' (the surrounding letters on a QWERTY keyboard). Concatenate successive key pressed to form codewords, then use FEC to find the dictionary word which has the maximum likelihood.

Getting fancy, one could use the results to train the system, fine tuning the probabilities as it goes. In this way, it doesn't matter where you type (or even the spacial relationship of the "keys"), as long as the location you use for each letter averages out to be reasonably consistent. In time the system will train itself to so English words come out, meaning the key mappings are probably correct.

For example, one could start typing "QWERTY" style, change to typing "Dvorak" and the system would put out gibberish for a while, then start putting out English again as the probabilities converged.

Well, I'm afraid I wouldn't like it. It seems it continues the only thing that is annoying me in iOS input method - not writing what I actualy type. Sorry, too often I use words it doesn't know (maybe in english it's better, but in polish/russian/ukrainian it's quite a big problem). It would mean disaster when using this app, isn't it? Does it support other languages at all? How about cyryllic script? Does it allow to switch between languages easly? Does it replace standard input method everywhere in iOS?
