  1. Variables of interest include: number of placed tools, number of tool touches, total time used in trials, time per tool placed in each trial. A dash represents an incomplete trial, T1 =trial 1, T2 =trial 2, and T3 =trial 3. The time is measured in seconds and the distance is measured in millimeters. Note that three subjects did not complete all trials.
