Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. A measure of the convergence or divergence of a pair of light rays, defined as the reciprocal of the distance between a point of reference and the point at which the rays intersect.
  • n. The inward or outward turning of one or both eyes that occurs when focusing on an object.

  • And those movements, they're called vergence movements, are the movements that I had to learn to make.

  • A person with strabismus, a person with misaligned eyes doesn't make those vergence movements.

  • This definition implies that communication is a process of con vergence (or divergence) as two or more individuals exchange information in order to move toward each other (or apart) in the meanings that they give to certain events.

  • Study authors varied focal point and the vergence distance

  • The participants responded that they experienced more eye strain and fatigue from the video with different vergence and focal distances, a feature of 3D that has long been supposed to cause eye strain.

    Ars Technica

  • A second part of the study found that though 3D was fatiguing in general, the participants had more problems with distant displays showing an image with a vergence distance deeper than the screen and with near displays showing images popping out of the screen.

    Ars Technica

  • For 2D video, these points are always one and the same, but in 3D video the vergence distance varies, and can be either deeper than the surface of the screen or in front of it.

    Ars Technica

  • In the video clips, the authors were varying the focal point, which is the surface of the screen, and the vergence distance, which is where in the image the eyes are trying to focus on.

    Ars Technica

  • "While we use specialist 2D to 3D conversion technology for the transformation of the imagery, iQ gives us the ability to review the results in realtime at full resolution and also to interactively manipulate the 3D vergence to get the stereo image working perfectly," said

  • Finally, vergence abnormalities reported here could be present only for patients who can modulate their tinnitus.
