Haptic device attribute control
First Claim
1. A method for providing control over force output from a force feedback device, said force feedback device being coupled to a host computer, the method comprising:
- providing a graphical control in a graphical environment displayed by said host computer, wherein a user of said force feedback device can adjust said graphical control to a plurality of settings by interfacing via said graphical environment with said graphical control, said graphical control being settable to a particular one of said plurality of settings; and
modifying a magnitude of a plurality of force sensations output by said force feedback device in accordance with said particular setting of said graphical control, B wherein the relative magnitude of said plurality of force sensations with respect to each other remains substantially unchanged regardless of which of said settings of said graphical control is set.

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.

10. A force feedback device including a control over force output from said force feedback device, sad force feedback device being coupled to a host computer, the force feedback device comprising:
-
a movable member having a position or orientation adjustable by a user of said force feedback device;
at least one actuator coupled to said device and capable of outputting a plurality of force sensations to be felt by said user, each force sensation having a magnitude;
at least one sensor that senses motion or position of said movable member, and a control coupled to said force feedback device, wherein a user of said force feedback device can set said control to a particular one of a plurality of available settings, and wherein the magnitude of each force sensation output by said force feedback device is scaled in accordance with said particular setting of said control, wherein the relative magnitudes of said force sensations with respect to each other remains substantially unchanged regardless of which of said settings of said control is set, and wherein said control is integrated in-line directly in a power controlling system of said at least one actuator of said force feedback device such that said control directly adjusts power to said at least one actuator. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
