IEEE Transactions on Visualization and Computer Graphics
|October 3, 2023
Summary
This study presents a 5G-powered virtual reality system for immersive 360° video calls. It achieves visually identical streams using 80% less data by employing efficient foveated compression over cellular networks.
Area of Science:
- Computer Science
- Electrical Engineering
- Human-Computer Interaction
Background:
- Mobile devices and cellular networks are increasingly used for internet access.
- Streaming high-quality 360° video over cellular networks faces bandwidth limitations.
- Low-latency techniques like foveated rendering are crucial for efficient video compression but challenging on traditional cellular networks.
Purpose of the Study:
- To demonstrate an end-to-end virtual reality telepresence system for streaming high-quality 360° video over 5G millimeter-wave (mmW) networks.
- To enable high-efficiency foveated compression on modern cellular networks, comparable to WiFi performance.
- To evaluate the system's visual quality and user perception of compressed video.
Main Methods:

01:15Depth Perception and Spatial Vision
700
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines.

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

01:06Virtual Work for a System of Connected Rigid Bodies
403
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.
