Method and system for adjusting an alignment of a head-mounted device within a moving vehicle

A method of adjusting an alignment of a head mounted display (HMD) worn by a user in a vehicle moving on a road relative to an inertial frame of reference, the method comprising:

• measuring orientation of the HMD relative to the inertial frame of reference via at least one inertial sensor coupled to the HMD;
• measuring orientation of the vehicle relative to the inertial frame of reference via at least one inertial sensor coupled to the vehicle;
• obtaining kinematic parameters associated with a movement of the vehicle relative to the inertial frame of reference;
• determining an occurrence of a specific kinematic event that meet predefined kinematic behavior of the vehicle, based on the kinematic parameters;
• and
• upon detection of the occurrence of the specific kinematic event, comparing readings of the at least one inertial sensor coupled to the HMD and the at least one inertial sensor coupled to the vehicle, to yield alignment parameters.

A non-transitory computer readable medium for adjusting an alignment of a head mounted display (HMD) worn by a user in a vehicle moving on a road relative to an inertial frame of reference, the computer readable medium comprising a set of instructions that, when executed, cause at least one computer processor to:

• measure orientation of the HMD relative to the inertial frame of reference via at least one inertial sensor coupled to the HMD;
• measure orientation of the vehicle relative to the inertial frame of reference via at least one inertial sensor coupled to the vehicle;
• obtain kinematic parameters associated with a movement of the vehicle relative to the inertial frame of reference;
• determine an occurrence of a specific kinematic event that meets predefined kinematic behavior of the vehicle, based on the kinematic parameters;
• and
• upon detection of the occurrence of the specific kinematic event, compare readings of the at least one inertial sensor coupled to the HMD and the at least one inertial sensor coupled to the vehicle, to yield alignment parameters.
