Abstract
The invention provides a viewing system including an augmented reality system that generates a visual presentation to a user based at least in part on an IPD of the user, and an IPD compensator that adjusts the visual presentation based on an IPD compensation factor.
Claims17
A viewing system comprising:
- an interpupillary distance (IPD) detector that is positionable to detect an IPD of a user and generate IPD data that includes a plurality of IPD values;
- a head movement detector device that is positioned to detect movement of a head of a user and generate head movement data that includes a plurality of head positions based on movement of the head of the user;
- a correlator connected to the IPD detector and the head movement detector device to generate a correlation between the IPD data and the head movement data such that different head positions have different associated respective IPD compensation factors;
- a storing system, being a software component executable by a processor, connected to the correlator to store the correlation;
- an augmented reality system having a light projector that generates a visual presentation to a user based at least in part on an IPD of the user;
- an IPD compensation factor calculator connected to the head movement detector device and operable to calculate a select IPD compensation factor based on the head movement data such that different head positions have different associated respective IPD compensation factors;
- and
- an IPD compensator that adjusts the visual representation based on the select IPD compensation factor.
