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,

  • on a palmtop computer
  • on a wearable computer
  • when operating a computer one-handed, by joystick, touchscreen, trackball, or mouse
  • when operating a computer with zero hands (i.e., by head-mouse or by eyetracker).

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.
