Controlling focal parameters of a head mounted display based on estimated user age

A computerized method for controlling focal parameters of a visual display based on ocular features, the method comprising:

• collecting, by a processor using at least one eye tracking sensor, ocular metric data associated with at least one ocular feature of a user's eye;
• calculating, by the processor, a user age estimate based on analysis of the ocular metric data using at least one machine learning algorithm and an associated ocular metric data set;
• calculating, by the processor, a confidence value associated with the user age estimate based on the analysis of the ocular metric data;
• and
• controlling, by the processor, at least one focal parameter of the visual display based on the calculated user age estimate and the associated confidence value.

One or more computer storage media having computer-executable instructions for controlling focal parameters of a visual display based on ocular features that, upon execution by a processor, cause the processor to at least:

• collect, via at least one eye tracking sensor of the visual display, ocular metric data associated with at least one ocular feature of a user's eye;
• calculate a user age estimate based on analysis of the ocular metric data using at least one machine learning algorithm and an associated ocular metric data set;
• calculate a confidence value associated with the user age estimate based on the analysis of the ocular metric data;
• and
• control at least one focal parameter of the visual display based on the calculated user age estimate and the associated confidence value.
