A tool for the rapid evaluation of input devices using Fitts' law models
Ian Scott MacKenzie, William A. S. Buxton · ACM SIGCHI Bulletin · 1993
A tool for building Fitts' law models is described. MODEL BUILDER runs on the Apple Macintosh using any device which connects to the Apple Desktop Bus. After 16 blocks of trials taking about 4--5 minutes, the program provides an immediate (albeit tentative) statistical analysis, showing the coefficients in the prediction equation, the coefficient of correlation, and a regression line with scatter points. MODEL BUILDER can be retrieved anonymously by researchers, educators, developers, or anyone with access to INTERNET through file-transfer-protocol (FTP).
