Figure 1

Top view of the experimental setup (A). The Optotrak system was used for hand movement recording, and the ASL eye tracker was used for eye movement recording. Two-segment movements were made from a starting position (SP) to a first target (T1), and then to a second target (T2). Two different target sizes (0.5 cm and 4.0 cm in diameter) were used for T1 to vary an accuracy constraint. B: Experimental conditions related to hand termination requirement. For all conditions, the eyes made two-segment movements from the SP to T1, and subsequently to T2. Conversely, hand movements were varied across conditions. The small-T1 size conditions are shown in the figure.
