Generalized Fitts' law model builder

A tool for designing experiments, capturing data, and building Fitts’ law models is described. The software runs on an IBM or compatible computer equipped with an appropriate graphical display and selection device (e.g., mouse, joystick). Features intended for HCI educational purposes or experimental research are included, making this a very powerful utility for research in input techniques or Fitts’ law. The software is available via anonymous FTP through the internet.
