Head-Mounted Device with Double Vision Compensation and Vergence Comfort Improvement

A method of operating an electronic device, comprising:

• with one or more image sensors, acquiring passthrough content;
• with a graphics rendering subsystem, generating virtual content;
• obtaining prism prescription values for correcting double vision or improving vergence comfort;
• computing compensation parameters based on the prism prescription values;
• modifying the passthrough content based on the compensation parameters;
• and
• displaying a blended version of the modified passthrough content and the virtual content.

A method of operating an electronic device, comprising:

• with one or more image sensors, acquiring passthrough content;
• with a graphics rendering subsystem, generating virtual content;
• displaying a stimulus point;
• while the stimulus point is being displayed, monitoring a point of gaze to estimate a misalignment between the point of gaze and an expected point of gaze;
• computing compensation parameters based on the estimated misalignment;
• modifying the passthrough content based on the compensation parameters;
• and
• displaying a blended version of the modified passthrough content and the virtual content.

A method of operating an electronic device, comprising:

• with a graphics rendering subsystem, generating virtual content having left eye content and right eye content, wherein the graphics rendering subsystem is configured to generate the virtual content based on a first virtual camera that imposes constraints defining a first point of view from which the left eye content is being rendered at the graphics rendering subsystem and a second virtual camera that imposes constraints defining a second point of view from which the right eye content is being rendered at the graphics rendering subsystem;
• mitigating double vision or improving vergence comfort by modifying a selected one of the left eye content and the right eye content to produce modified virtual content;
• and
• with one or more displays, outputting the modified content.
