Dasher in Korean - a six-page paper by David MacKay: | pdf | postscript |

Most of the original research work on Dasher was done by David Ward.

Between 1999 and 2002, we made three assessments of Dasher, comparing it with alternative text entry systems on three platforms.

  • One-handed text-entry using mouse alone
  • Text-entry on a pocket PC with a stylus
  • Text-entry with no hands, using Dasher with an Eyetracker (Further information about hardware)
The details can be found in David Ward's PhD thesis and in the publications listed below.
