Viewing system with interpupillary distance compensation based on head motion

A viewing system method:

• detecting, with an interpupillary distance (IPD) detector, a plurality of IPD's of a user to generate IPD data that includes a plurality of IPD values;
• detecting, with a head movement detector device, movement of a head of a user to generate head movement data that includes a plurality of head positions based on movement of the head of the user;
• generating, with a correlator connected to the IPD detector and the head movement detector device, a correlation between the IPD data and the head movement data such that different head positions have different associated respective IPD compensation factors;
• storing, with a storing system, being a software component executable by a processor, connected to the correlator, the correlation;
• generating, with an augmented reality system having a light projector, a visual presentation to a user based at least in part on an IPD of the user;
• calculating, with an IPD compensation factor calculator connected to the head movement detector device, a select IPD compensation factor based on the head movement data such that different head positions have different associated respective IPD compensation factors;
• and
• adjusting, with an IPD compensator, the visual representation based on the select IPD compensation factor.
