THE TYPING EXPERIENCE
What if I make a spelling or typing mistake while entering text?
Eatoni's WordWise is very robust in the face of spelling or typing errors. As with a QWERTY keyboard, when you make a single mistake, the text you end up with still looks very much like what you intended. We call this "sensitivity to errors." With WordWise, a 1-key error translates into an average of 1.27 display errors (QWERTY is of course 1.0). With T9®, the figure is 2.57, so errors tend to blow up quite severely. Coupled with the confusing display instability (see Question 6.2), it is very common to find yourself typing in one of these other products with no idea at all if things are going to work out and if, or where, you made an error. We call this the "lost until space" problem. Until you hit the space key, you don't know whether these word-guessing systems are going to pull your desired word out of the hat or produce complete gibberish (which you will then need to erase and may have to re-enter using Multi Tap).
How well does your software handle surnames? URLs? email addresses?
We have no trouble at all with any of these. Just use LetterWise mode to quickly enter anything at all.
What about user studies?
The results of Several rigorous user studies of both LetterWise and WordWise are available in our Research section.
