The One-Finger Keyboard

Written By: Usree Bhattacharya on April 11, 2009 4 Comments

Behold, the one-finger keyboard! This is what it does:

Dasher is a one finger user interface that allows text entry without a keyboard.
Keyboards are inefficient for two reasons: they do not exploit the redundancy in normal … all » language; and they waste the fine analogue capabilities of the user’s motor system (fingers and eyes, for example). I describe a system intended to rectify both these inefficiencies. Dasher is a text-entry system in which a language model plays an integral role, and it’s driven by continuous gestures. Users can achieve single-finger writing speeds of 35 words per minute and hands-free writing speeds of 25 words per minute. Dasher is free software, and it works in all languages, and on many platforms. Dasher is part of Debian, and there’s even a little java version for your web-browser.

Now watch a demonstration. For the LOLs, watch starting from the 3:52 minute mark!

    this is real, right? cause it’s AWESOME. The site looks legit, even though the “Metafaq” section seems like a jab at the geeky tendency to attach “meta” to everything.

    Although having half your screen taken up by the typing interface isn’t a good selling point, since that cuts out probably its strongest application — mobile computing devices.

    I did some searches, and it looks legitimate. The company’s been around for a while, too, so far as I can tell.

    They DO get a little meta!

    have you seen head tracking with the Wii remote?

    they should combo the two!

    OMG this is amazing! Wow! Wow! Wow! I need to get me one of those!

    Maybe you could combine the two?
