title: Can augmented force feedback facilitate virtual target acquisition tasks?
abstract: This study investigates facilitation of a manual target acquisition task by the application of appropriate force feedback through the control device (e.g., mouse, joystick, trackball). Typical manual movements with these devices were measured, and models of such movements were used to predict an intended target location from an initial portion of a trace. Preferred shapes and sizes for feedback force functions to be applied were empirically determined by collecting preference ratings and measuring task completion times. The general experimental task that is typical for an office situation, but findings appear generalizable to some medical and surgical situations (e.g. laparoscopy, catheterization) where a certain target has to be reached whose precise location may be known or unknown.
