“…When examining results by the task performance measures, we observe an emerging trade-off between production and other measures. In many studies, teleoperators could execute more total actions as they controlled more platforms (e.g., Crandall & Cummings, 2007;Lif et al, 2007;Squire et al, 2006). However, increasing the number of platforms also increased error rates in targeting and navigation (e.g., Galster, Knott, and Brown, 2006), and it tended to increase reaction times (e.g., Chadwick, 2006;Levinthal & Wickens, 2007).…”
