Abstract:	This talk concerns the design and data analysis of an experiment conducted to study the use of mobile computing devices for real-time navigation and communication. Attention is restricted to studying the effects of display type and visual presentation format on navigational performance. The planned experiment was a 2x3 design in two treatment factors, with 12 subjects and six observations per subject. The experiment was run over 24 days. Each subject was involved for two distinct days, with three observations collected per day. Days are viewed as whole plots and runs within a day as split plots, with one between-whole-plots factor and one within-whole-plots factor. To collect an observation, a subject navigated one of six paths. The design used is balanced for path and run order. Each path included north, south, east, and west legs.The belated inclusion of leg direction as a third factor of interest made this a split-split-plot design. The observation for one run could not be used.
