Abstract: A control device comprising a lever provided with a magnetic dipole and able to move, at least in rotation, relative to a support about an axis. The control device includes a measuring device configured to measure a magnetic field generated by the magnetic dipole, and a monitoring system for monitoring the integrity of the control device. The monitoring system is configured to signal an anomaly using an alarm when a first norm of a first vector difference between the current magnetic field and a first reference magnetic field relating to an estimated orientation of the lever, is greater than a first magnetic field threshold for a duration greater than a duration threshold.

Abstract: The disclosure is directed at a method and apparatus for producing and displaying how-to videos. The production of the how-to video includes the functionality of the insertion of a coaching tip within the how-to video which allows a producer of the video to embed pauses and annotations within the video for a viewer.
