INSTRUMENT INTERFACE FOR REDUCING EFFECTS OF ERRATIC MOTION
First Claim
1. An instrument interface comprising:
- motion sensors configured to sense motion representative of user input in at least two dimensions and produce two-dimensional motion data;
a first filter configured to filter the motion data corresponding to a first dimension; and
a second filter configured to filter the motion data corresponding to a second dimension, wherein first parameters for the first filter are independently reconfigurable by the user from second parameters for the second filter through software operation.

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.

19. A method for operating an instrument interface, the method comprising:
-
sensing, with motion sensors, first user-input motion in at least two dimensions; producing two-dimensional motion data representative of first the user-input motion; filtering, with a first filter having adjustable first filter parameters, the motion data for a first dimension; filtering, with a second filter having adjustable second filter parameters, the motion data for a second dimension; independently reconfiguring at least the first filter parameters from the second filter parameters through software operation based at least upon the first user-input motion. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
