Abstract: Apparatus and methods to reduce effects of erratic motion input during operation of an instrument via a graphical user interface are described. Spatial motion input received from a user may be filtered using filter parameters obtained during a calibration procedure. The filtered motion input may be used to predict a trajectory of a cursor or object used to select an icon or text. The icon or text may be latched to the approaching cursor or object. The combination of motion smoothing and latching may improve ease-of-use of the graphical user interface for individuals having neuromuscular disorder, or users operating instruments in high-vibration environments.
