Ring-Writer uses an extremely simple, but effective, gesture recognition system. Our aim has been to provide a convenient way for entering punctuation and special symbols without having to call up a virtual keyboard or character recognizer.
The editing gestures allow you to handle text in a more direct and intuitive way than with the mouse, and the action gestures, combined with Ring-Writer commands, replace pull-down menus.
The current gesture definitions have been tested extensively in-house, and work well for us. However, there may be some shapes that some people find difficult to do. Please tell us if you have problems with any of the gestures, specifying which gesture you were trying to make, and whether the gesture simply did not work, or whether it was incorrectly taken for another gesture, and if so, which one.
Here are some general tips which will help you get close to 100% recognition:
1) Make the shapes as large as you can, while of course avoiding the sector ring.
2) Make curves as rounded as possible, and angles as sharp, or “pointed”, as possible – avoid “open” angles (for instance in “Add Word”, or the Command gesture), since these are too easily seen as curves.
3) Use slightly acute angles, rather than right-angles, in the Return gesture, “L” for Letter Mode, and the square-bracket symbols.
4) You don’t have to draw the shapes in the various double-gestures quickly: what counts is the time delay between the end of the first gesture, and the pen-down on the second gesture.
