Technology Jargon, acronyms and abbreviations explained
Ever wondered what all those techie words and acronyms actual mean?... well you're in the right place to find out! We have an extensive list of the most common tech words used in Virtual Reality (VR) and Augmented Reality (AR)
PPI, or "Pixels Per Inch," is a fundamental measure in the world of display technology and screen resolution. It quantifies the density of pixels within a one-inch square area on a screen's surface. In essence, PPI indicates how tightly packed the pixels are on the screen, and it directly influences the level of detail and clarity that can be achieved in the displayed images.The importance of PPI lies in its role in defining the overall image quality and sharpness of displays, including those used in devices like smartphones, tablets, monitors, and VR headsets. A higher PPI means that there are more pixels within each inch of the screen, resulting in crisper and more detailed visuals. Conversely, a lower PPI may lead to a less sharp and less detailed image.When evaluating and comparing displays, understanding PPI is essential, as it offers insights into the potential visual fidelity and clarity of the screen, making it a crucial factor for consumers when choosing electronic devices.

PPD
PPD, which stands for "Pixels Per Degree," is a crucial metric in the realm of virtual reality (VR) and display technology. It quantifies the pixel density or resolution of a display concerning your field of view and viewing distance. In simpler terms, PPD tells you how many pixels are packed into every degree of your visual field when you're immersed in a VR experience.The significance of PPD lies in its ability to determine the level of detail and clarity you can expect in the virtual world. A higher PPD equates to finer detail and greater clarity because there are more pixels available per degree of your visual field. This enhancement reduces the "screen door effect" (those visible grid-like lines between pixels) and ultimately enhances the overall image quality. When assessing VR headsets and displays, PPD is a vital factor to consider, as it directly impacts the visual richness and immersion of the VR experience.

Standalone
When Standalone (also referred as 'Untethered') is referenced in Virtual Reality - it simply means headsets that are free from wires, so don't require being physically attach to a PC. The Oculus Quest and Quest 2 are perfect examples of standalone headsets, as is the DecaGear 1. Examples of a tethered headset (attached to a PC), would be the Valve Index and Oculus Rift S.
Standalone headsets are often preferred to the tethered kind because it gives the user more freedom to move in their environment without the restriction of wires.

XR
XR is an acronym for 'Extended Reality'. In a nutshell the phrase represents any sort of technology that alters reality for the user by fogging the gap between real and digital worlds. Essentially Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) all fit within the same Realm of XR media.
