Optics Express
|May 3, 2018
Summary
Visual comfort in stereoscopic videos declines with greater disparity and faster motion. An objective evaluation method accurately predicts subjective comfort levels, improving viewer experience.
Area of Science:
- Computer Vision
- Human-Computer Interaction
- Visual Perception
Background:
- Stereoscopic video viewing can cause visual discomfort.
- Factors like disparity and motion significantly impact viewer experience.
- Objective measures are needed to predict visual comfort.
Purpose of the Study:
- To propose an objective evaluation method for stereoscopic video visual comfort.
- To investigate the impact of horizontal disparity, vertical disparity, and motion on visual comfort.
- To validate the proposed objective method against subjective evaluations.
Main Methods:
- Conducted three experiments to assess visual comfort.
- Manipulated horizontal disparity, vertical disparity, and motion velocity.
- Developed an objective evaluation measure based on these factors.
Main Results:
- Visual comfort decreases as disparity magnitude and motion velocity increase.
- Both planar and depth motion negatively affect visual comfort.
- The proposed objective method showed good consistency with subjective results.
Conclusions:
- Disparity and motion are critical factors for stereoscopic visual comfort.
- The developed objective method reliably predicts viewer comfort.
- This method can aid in optimizing stereoscopic video content for better viewing.

Velocity of an Object

Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Equation of Motion: General Plane motion

In the context of a rigid body's movement within a general plane, it is important to understand that this motion is typically triggered by external forces or couple moments exerted onto it. This principle can be explained through Newton's second law, which stipulates the translational motion of the body's center of mass along each axis.
Moreover, the body's center of mass experiences a rotational effect as a result of these couple moments. This rotation can be articulated as the...

Potential Due to a Polarized Object

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Potential Due to a Magnetized Object

Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...
