1. A user to machine interface comprising:
- a remote control with at least a trigger button,a communication link between the remote control and a display,a motion sensor for generating motion signals at least partially representative of motion of the remote control, anda processor configured to;
process said motion signals in at least one of a first mode and a second mode of operation of said interface, andswitch the operation of the interface between said first and second modes, at least one of which enables operation of said interface based on motion of the remote control,wherein at least a switching decision is based on an evaluation of a combination of i) a duration δ
ON indicative of a length of time of an ON state during which a user presses the trigger button in a press and release cycle of the trigger button, and ii) a function Qmotion representative of a quantity of motion imparted to the remote by the user, derived from the motion signals including at least one moment during said ON state.

Abstract
A remote control, such as a 3D air mouse, includes motion sensors used to measure position/orientation in space to alternatively control a cursor on a display, recognize gestures by the user so that data/commands can be entered into an electronic system being controlled or the like. Timed sequences of pressing a single trigger button and the quantity of motion during said sequences are both timed in relation to thresholds to switch between modes.

14. A method of operating a user to machine interface comprising:
-
acquiring signals from a motion sensor, said signals being at least partially representative of motion of a remote control held by a user, processing the signals from the motion sensor in one of a first mode and a second mode, at least one of which enables operation of said interface based on motion of the remote control, and detecting pressing of a trigger button on the remote control by said user to switch between said first mode and said second mode, said method further comprising determining switching decisions between said first and second modes based on an evaluation of a combination of;
i) a duration δ
ON indicative of a length of time of an ON state during which the user presses the trigger button in a press and release cycle of the trigger button, and ii) a function Qmotion representative of a quantity of motion imparted to the remote by the user, derived from the motion signals including at least one moment during said ON state.

15. A remote control comprising:
-
at least a trigger button, a circuit to establish a communication link with a display, at least a motion sensor for generating motion signals at least partially representative of motion of the remote control, and a processor configured to; process said motion signals in at least one of a first mode and a second mode of operation of said remote, and switch the operation between said first and second modes, at least one of which enables operation of said remote control based on motion imparted to the remote by a user, wherein at least a switching decision is based on an evaluation of a combination of i) a duration indicative of a length of time of an ON state during which the user presses the trigger button in a press and release cycle of the trigger button, and ii) a function Qmotion representative of a quantity of motion imparted to the remote by the user, derived from the motion signals including at least one moment during said ON state.
