Abstract: The disclosed system for varifocal adjustments may include a frame, an optical lens pair supported by the frame, and a brake mechanism coupled to the frame. The optical lens pair may include a first lens that is movably coupled to the frame and a second lens that is fixedly coupled to the frame. The brake mechanism may be configured to frictionally stop movement of the first lens and to maintain a position of the first lens. Various other devices, systems, and methods are also disclosed.

Abstract: A flexure based guidance system for precision motion control includes a base that is fixed in position, a carriage that can move relative to the base, an actuator provides the force to move the carriage relative to the base, and one or more flexures arrays that each comprise two or more leaf flexure elements. The actuator causes the carriage to move relative to the base, which causes the flexure elements in the flexure array to flex. The leaf flexure elements are thin, compliant and deform, bend, or deflect in a deterministic manner when mechanically stressed. In some embodiments, stiffeners can be added to the flexures. The guidance system can be integrated into a varifocal head mounted display (HMD) to adjust a location of one or moveable elements in an optical system of the HMD to control a location of an image plane.

Abstract: Techniques are described for backlighting electronic headset display panels. The backlight can include a light guide plate that is illuminated via a light transmitting element that is coupled to a light source. The light guide plate, in turn, illuminates the display panel. The light source is located within the headset but is disposed remotely from the display panels. A photodiode is coupled to a surface of the light transmitting element and is configured to detect a characteristic of the light transmitted by the light transmitting element.

Abstract: A system for adjusting an interpupillary distance and an eye relief distance of a headset. The system can determine an interpupillary distance of a user and an eye relief distance of the user. The system can cause an adjustment assembly to adjust a first distance between the first lens and the second lens along a first axis based at least in part on the interpupillary distance and cause the adjustment assembly to adjust the optical assembly a second distance along a second axis that is orthogonal to the first axis based at least in part on the eye relief distance.

Abstract: A head mounted display (HMD) includes a set of one or more lenses defining an optical axis, a display configured to project light through the set of the one or more lenses, a voice coil actuator coupled with the display and configured to move the display along the optical axis, and a first guide that is separate from the first voice coil actuator and coupled with the first display to guide the movement of the first display. The HMD additionally includes a set of one or more position sensors configured to determine a position of the display long the optical axis and an electronic controller configured to receive information identifying a reference position of the display along the optical axis and generate one or more electrical signals for initiating a movement of the first display toward the first reference point along the optical axis.

Abstract: A head mounted display (HMD) includes an electronic display configured to display a virtual scene to a user, an optics block, an eye tracking system, and a varifocal actuation that mechanically changes a distance between the optics block and the electronic display. The varifocal actuation block is configured to change a location of an image plane of the HMD and includes a motor, a power screw coupled to the actuating motor configured to turn responsive to actuation of the motor, and a nut sled on the power screw that is coupled to the electronic display. The nut sled is configured to move back and forth along a length of the power screw responsive to the power screw being turned by the motor that results in movement of the electronic display relative to the optics block.

Abstract: A head-mounted display device includes a first set of one or more lenses and a first display configured to provide visual data through the first set of one or more lenses. The head-mounted display device further includes a first stepper motor mechanically coupled to the first display, and the first stepper motor is configured to move the first display along a first axis by rotating a rotatable component of the first stepper motor. The head-mounted display device further includes a first electronic controller configured to (i) determine a first position of the first display, (ii) receive information identifying a second position of the first display, and (iii) generate one or more electrical signals that cause the first stepper motor to move the first display from the first position to the second position along the first axis.
