Embodiments of the invention include a method to determine a binocular alignment, the method comprising: measuring a disassociated phoria of a first eye and a second eye of a patient at an apparent distance; and determining an accommodative convergence of the first eye and the second eye at the apparent distance using the measured disassociated phoria. In other embodiments, a system to determine a binocular alignment comprises a stereo display, for a projection of images for a first eye and a second eye; an accommodation optics, to modify the projection of the images according to an apparent distance; an eye tracker, to track an orientation of the first eye and the second eye; and a computer, coupled to the stereo display, the accommodation optics and the eye tracker, to manage a determination of the binocular alignment.

Techniques are directed to user profiles for viewing devices. A user profile storing one or more defined parameters may be received. The one or more defined parameters may represent viewing information. Descriptive information about the media information to be viewed on the viewing device may be received. One or more settings in a viewing device may be adjusted based on the one or more defined parameters in the user profile and the descriptive information. Other embodiments are described and claimed.

A lens bears a plurality of roll-coated layers to pass, to one eye of a viewer, a first image, in a first band of wavelengths, that is appropriate for 3D viewing of a stereoscopic image.

Systems, methods, and computer-readable media for integrating and optimizing a surgical suite. An ophthalmic suite can include a surgical console, a heads-up display communicatively coupled with a surgical camera for capturing a three-dimensional image of an eye, and a surgical suite optimization engine. The surgical suite optimization engine can performs a wide variety of actions in response to action codes received from the other components in the surgical suite. The surgical suite optimization engine can be integrated within another component of the surgical suite, can be a stand-alone module, and can be a cloud-based tool.

Shutter glasses, used for watching a display device, comprises a first lens, a second lens, a driving circuit and a processor; both the first lens and the second lens are divided into a plurality of sections from top to bottom, and the driving circuit is connected to the plurality of sections of the first lens and the plurality of sections of the second lens to drive the corresponding sections to be opened and transparent; the processor is connected to the driving circuit to determine an updated area of a display image of the display device, which is currently updated and to determine the sections of the first lens and/or the sections of the second lens corresponding to the updated area, and to control the driving circuit to drive the sections of the first lens and/or the sections of the second lens corresponding to the updated area to be opened.

Techniques and mechanisms for determining a level of accommodation to be provided by an eye-mountable device (EMD) for a user viewing a 3D stereoscopic display. In one embodiment, the EMD in disposed in or on an eye of the user, and an angle of vergence between the user's eyes is detected. Based on the angle of vergence, the EMD provides a level of accommodation that results in the user having a blurred viewing of an object in the stereoscopic display. The blur induces the user to change the accommodation provided by the eye on which, or in which, the EMD is disposed. Inducing the user to perform such a change in the eye's accommodation more closely approximates what the user would do when viewing real world physical objects. This tends to result in a better viewing experience by the user. In another embodiment, the angle of vergence is detected based on exposure of the EMD to a magnetic field.

The present invention discloses 3D shutter glasses and a 3D display system. The 3D shutter glasses comprise a left eye glass and a right eye glass, wherein both the left eye glass and the right eye glass comprise a light transmitting hole array, wherein the left eye glass and the right eye glass alternately control the corresponding light transmitting hole array to be sequentially opened according to a first predetermined time to receive left eye data images and right eye data images, and the first predetermined time is a spacing interval of alternately sending the left eye data images and the right eye data images. With the aforesaid procedure, the present invention is capable of effectively relieving the visual fatigue as watching 3D images.

A method of digital continuous and simultaneous three-dimensional painting and three-dimensional drawing with steps of providing a digital electronic display capable of presenting two pictures for a right eye and a left eye; providing means for creating a continuous 3D virtual canvas by digitally changing a value and sign of horizontal disparity between two images for the right eye and the left eye and their scaling on the digital electronic display corresponding to instant virtual distance between the user and an instant image within the virtual 3D canvas; providing at least one multi-axis input control device allowing digital painting or drawing on the digital electronic display; painting within virtual 3D canvas by providing simultaneous appearance of a similar stroke on the images for the right eye and the left eye on the digital electronic display.

A 3D glasses device incorporating real time tracking and a system for implementing the 3D glasses device for an immersive virtual reality experience includes 3D glasses that comprise: a frame, a pair of lens, and a real-time tracking unit, which enables the position and orientation to be observed by optical tracking systems featuring optical transmitters. In one exemplary implementation the 3D glasses device communicates with a client system during a session of digital media content rendering. The real-time tracking unit of the 3D glasses device has optical sensors activated when struck by light from an optical transmitter, communicates its position and orientation to the client system, which renders media content based in part on the tracking data, and shows the content on head-mounted display systems that are part of the device in order to produce an immersive virtual reality experience.

A display device for providing a virtual reality service is provided. The display device includes: a display configured to display a stereoscopic image; a user interface configured to receive a user command for enlarging or shrinking the stereoscopic image; and a processor configured to adjust a three-dimensional effect for the stereoscopic image to correspond to the user command when the user command is input, and control the display to display an enlarged image or a shrunk image in which the three-dimensional effect is adjusted.
