Abstract
A spotlight controller including a housing having a first control axis, a fixed base configured to mate with the housing, the housing rotatable relative to the base about a second control axis substantially perpendicular to the first control axis, a handle configured to engage the housing and pivot about the first control axis, a housing sensor arranged to detect the position of the housing relative to the base and generate a housing position signal, a handle sensor arranged to detect the position of the handle relative to the housing and generate a handle position signal, and a controller operatively connected to the housing sensor and the handle sensor, wherein the controller receives the housing position signal and the handle position signal and generates spotlight control signals based on the housing position signal and the handle position signal.
