Multi-axis joystick and transducer means therefore
First Claim
1. A multi-axis input transducer apparatus comprising:
- an at least quinary input element capable of input with respect to at least five frames of reference, a reflective element responsive to radiation from a source capable of emitting radiation eventually incident upon said reflective element; and
at least one reflected radiation detector responsive to radiation from said reflective element.

Abstract
The invention relates to improved multi-axis joysticks and associated multi-axis optical displacement measurement means. The displacement measuring means may include one or more light emitters and one or more light detectors, preferably mounted in a planar hexagonal array. The relative position of an adjacent movable reflector assembly can be measured in six degrees of freedom by variations in detected light amplitude. Various ergonomic configurations of six axis joystick embodiments which may be facilitated by the compact design of the transducer means are disclosed. Means for dynamically adjusting coordinate transformations for construction machinery control are also disclosed.

- 31. A joystick comprising a radiation source, a reflector, and reflected radiation sensor, at least one of which is movable with respect to at least one other of said three elements in at least three degrees of freedom, wherein said radiation source projects radiation eventually incident upon said reflector, said reflector reflects a varying reflected optical signal to said reflected radiation sensor in a manner which varies in at least three degrees of freedom, and said reflected radiation sensor senses at least a portion of said varying reflected optical signal.
