    • Gain and target size effects on cursor-positioning time with a mouse 

      Bohan, Michael; Thompson, Shelby; Scarlett, Deborah; Chaparro, Alex (2003-08)
      Movement time to align a cursor with targets on a computer screen a mouse was examined across settings of gain and target size. Empirical evidence was sought in light of previous suggestions that performance declines ...
    • Task and effector constraints on the kinematics of pointing movements 

      Bohan, Michael; McConnell, Daniel; Thompson, Shelby; Chaparro, Alex (2005-08)
      Recent work has emphasized the distinction between task and effector constraints underlying performance in Fitts' type discrete pointing tasks. We explored the relative contributions of these constraints in a cursor-pointing ...
