Methods and systems for providing constant-feel, multi-axis tactile cues
First Claim
1. A method for adjusting tactile cues for a controller having an axis and a cross-axis, the method comprising;
- obtaining an axis tactile cue in response to a position of the controller along the axis;
scaling a cross-axis controller position to generate a scaled cross-axis controller position;
scaling a cross-axis controller force to generate a scaled cross-axis controller force;
combining the scaled cross-axis controller position and the scaled cross-axis controller force to generate an adjustment factor; and
adjusting the axis tactile cue in response to the adjustment factor to generate an adjusted axis tactile cue to be applied along the axis of the controller;
wherein the axis tactile cue has a depth and a width, and the adjusted axis tactile cue has one of an adjusted depth and an adjusted width;
wherein the axis and cross-axis are perpendicular;
wherein the controller is coupled to a servo, the servo coupled to a linkage to control a rotor of a rotary wing aircraft;
wherein the controller is coupled to the servo in a fly-by-wire system with no direct mechanical connection between the controller and the servo and with no direct mechanical connection between the controller and the linkage.

Abstract
A system for adjusting tactile cues includes a controller having an axis and a cross-axis; an axis tactile cue generated in response to the position of the controller along the axis; a position scaling unit scaling a cross-axis controller position to generate a scaled cross-axis controller position; a force scaling unit scaling a cross-axis controller force to generate a scaled cross-axis controller force; a combiner combining the scaled cross-axis controller position and the scaled cross-axis controller force to generate an adjustment factor; and an adjuster adjusting the axis tactile cue in response to the adjustment factor to generate an adjusted axis tactile cue.
