A user input system, comprising: a movement interface configured to receive movement data representative of user manipulation of a control mechanism; a movement calibration system configured to: a) process movement data to determine calibrated movement data based at least in part on a movement space normalized using at least qualification zones, each sized and positioned to capture a certain portion of the movement data for a particular perimeter region to qualify peak excursions of the control mechanism in one or more axes, b) monitor transit events in the qualification zones indicated by the movement data to maintain peak hold values in the one or more axes and resultant average values derived from at least an averaging function applied to sequences of samples of the peak excursions in each of the qualification zones, and c) establish the updates to the qualification zones based at least on performing comparisons among the peak hold values and the resultant values, wherein the peak hold values for the qualification zones are updated to reflect the peak excursions in associated qualification zones based on the peak excursions exceeding current peak hold values for the associated qualification zones, and wherein the peak hold values are reduced by a predetermined amount based on the peak excursions in the associated qualification zones falling below the current peak hold values for the associated qualification zones; and a communication interface configured to provide the calibrated movement data for use in controlling one or more user interface elements with the control mechanism wherein the movement calibration system is further configured to: perform the comparisons by at least determining outermost values in the one or more axes among the peak hold values and the resultant values for each of the qualification zones, and to establish the updates by at least positioning the qualification zones based on associated ones of the outermost values. a movement interface configured to receive movement data representative of user manipulation of a control mechanism; a movement calibration system configured to: a) process movement data to determine calibrated movement data based at least in part on a movement space normalized using at least qualification zones, each sized and positioned to capture a certain portion of the movement data for a particular perimeter region to qualify peak excursions of the control mechanism in one or more axes, b) monitor transit events in the qualification zones indicated by the movement data to maintain peak hold values in the one or more axes and resultant average values derived from at least an averaging function applied to sequences of samples of the peak excursions in each of the qualification zones, and c) establish the updates to the qualification zones based at least on performing comparisons among the peak hold values and the resultant values, wherein the peak hold values for the qualification zones are updated to reflect the peak excursions in associated qualification zones based on the peak excursions exceeding current peak hold values for the associated qualification zones, and wherein the peak hold values are reduced by a predetermined amount based on the peak excursions in the associated qualification zones falling below the current peak hold values for the associated qualification zones; and a communication interface configured to provide the calibrated movement data for use in controlling one or more user interface elements with the control mechanism wherein the movement calibration system is further configured to: perform the comparisons by at least determining outermost values in the one or more axes among the peak hold values and the resultant values for each of the qualification zones, and to establish the updates by at least positioning the qualification zones based on associated ones of the outermost values.
