Methods for controlling performance of extended reality display systems

A method for displaying virtual contents using wearable electronic device, comprising:

• determining, by a wearable electronic device, a sighting center for a first eye of a user wearing the wearable electronic device;
• estimating, by the wearable electronic device or a remote computing device connected to the wearable electronic device via a network, an error or precision for the sighting center;
• determining a range of operation for a focal distance or a focal plane at the focal distance based at least in part upon the error or the precision and a criterion pertaining to vergence and accommodation of binocular vision of virtual contents with the wearable electronic device;
• adjusting a virtual content into an adjusted virtual content for presentation with respect to the focal plane or the focal distance based at least in part upon the range of operation;
• determining whether a render position error or precision is to be updated based at least in part upon one or more criteria;
• estimating a first error or precision for the sighting center;
• and
• adjusting the range of operation into a smaller range of operation, wherein the smaller range of operation comprises a range of distances for the focal plane or the focal distance, and the virtual content with respect to the focal plane or the focal distance is rendered according to the smaller range of operation.

A computer program product comprising a non-transitory machine readable storage medium having stored thereupon a sequence of instructions which, when executed by a microprocessor, causes the microprocessor to perform a set of acts, the set of acts comprising:

• determining, by a wearable electronic device, a sighting center for a first eye of the user wearing the wearable electronic device;
• estimating, by the wearable electronic device or a remote computing device connected to the wearable electronic device via a network, an error or precision for the sighting center;
• determining a range of operation for a focal distance or a focal plane at the focal distance based at least in part upon the error or the precision and a criterion pertaining to vergence and accommodation of binocular vision of the virtual contents with the wearable electronic device;
• adjusting a virtual content into an adjusted virtual content for presentation with respect to the focal plane or the focal distance based at least in part upon the range of operation;
• determining whether a render position error or precision is to be updated based at least in part upon one or more criteria;
• estimating a first error or precision for the sighting center;
• and
• adjusting the range of operation into a smaller range of operation, wherein the smaller range of operation comprises a range of distances for the focal plane or the focal distance, and the virtual content with respect to the focal plane or the focal distance is rendered according to the smaller range of operation.
