Abstract
In a force-reflection system wherein a basic force pattern including a plurality of behavioral attributes is applied to a user-moveable member, apparatus and methods are disclosed for altering one or more of the behavioral attributes without changing the basic force pattern. The invention may be used to adjust attributes such as amplitude maximum and average, play-out rate, and play-out lead/lag in conjunction with any type of user-manipulable member, including a joystick, wheel, yoke, or non-contact arrangement. The invention may be implemented at a high or low level, and arrays of haptic controls or equivalent graphical user interface (GUI) elements may be used to define haptic force temporal sequences for replay.
