<p>
 Dasher is an information-efficient text-entry interface,
 driven by natural continuous pointing gestures.
 Dasher is a competitive text-entry system wherever
 a full-size keyboard cannot be used - for example,
<ul>
<li> on a palmtop computer;
<li> on a wearable computer;
<li> when operating a computer one-handed, by joystick, touchscreen, trackball, or mouse;
<li> when operating a computer with zero hands (i.e., by head-mouse or by eyetracker).
</ul>
 The eyetracking  version of Dasher   allows an experienced user to write text
 as fast as normal handwriting - 25 words per minute;
 using a mouse, experienced users can write at 39 words per minute.

  
</p>
<p>
 Dasher can be used to write efficiently in
 <a href='/dasher/websource/portuguese/languages'>any language</a>.
