Claim of US Patent No. 10,251,241

1. A computing device comprising:a processor configured to:
determine a gesture made by the computing device, the gesture determination based on motion of the computing device;
navigate a user interface displayed on the computing device when the gesture is along a first axis of the computing device, wherein the gesture along the first axis is a fling gesture performed by moving the computing device by translation along the first axis and used to switch the active mode based on the fling direction;
adjust a light output of a luminaire when the gesture is along a second axis of the computing device, wherein:
the luminaire includes at least one solid-state light source configured to output light;
the gesture along the second axis is a pitch gesture performed by angularly lifting and lowering the computing device to provide a continuous range of pitch angles;
the control signal is based on the pitch angle; and
the pitch angle is dependent upon gravitational forces acting on the computing device along the first axis, the second axis, and a third axis of the computing device;
perform at least one error correction when determining the pitch angle to increase the accuracy of the pitch gesture when the computing device is not held flat when performing the pitch gesture, wherein the error originates from non-zero gravitational forces along the first axis and the third axis when the computing device is not held flat; and
confirm or revert the adjustment of the light output of the luminaire when the gesture is around the third axis of the computing device, wherein the gesture around the third axis is a tilt gesture performed by rotating the device in a direction about the third axis to confirm the selected option or revert to the previously selected option based on the tilt direction around the third axis; and
a communication module configured to transmit a control signal to the luminaire, wherein the control signal adjusts the light output of the luminaire based on the gesture along the second axis of the computing device.
