![]() The most popular types of cross-hair in modern scopes are variants on the duplex cross-hair, with bars that are thick on the perimeter and thin out in the middle. Thicker bars are much easier to discern against a complex background, but lack the precision of thin bars. While the traditional thin crossing lines are the original and still the most familiar cross-hair shape, they are really best suited for precision aiming at high contrast targets, as the thin lines are easily lost in complex backgrounds, such as those encountered while hunting. Motion pictures and the media often use a view through crosshairs as a dramatic device, which has given crosshairs wide cultural exposure. Telescopic sights for firearms, generally just called scopes, are probably the device most often associated with crosshairs. Another candidate as inventor is the amateur astronomer William Gascoigne, who predated Hooke. The reticle is said to have been invented by Robert Hooke, and dates to the 17th century. Most commonly associated with telescopic sights for aiming firearms, crosshairs are also common in optical instruments used for astronomy and surveying, and are also popular in graphical user interfaces as a precision pointer. Crosshairs are typically represented as a pair of perpendicularly intersecting lines in the shape of a cross, "+", though many variations of additional features exist including dots, posts, concentric circles/ horseshoes, chevrons, graduated markings, or a combination of above. There are many variations of reticle pattern this article concerns itself mainly with the most rudimentary reticle: the crosshair. Both terms may be used to describe any set of patterns used for aiding visual measurements and calibrations, but in modern use reticle is most commonly used for weapon sights, while graticule is more widely used for non-weapon measuring instruments such as oscilloscope display, astronomic telescopes, microscopes and slides, surveying instruments and other similar devices. Today, engraved lines or embedded fibers may be replaced by a digital image superimposed on a screen or eyepiece. Reticle of Bell & Howell Pocket Comparator Reticle accessory (PD-8) used in sniper riflesĪ reticle, or reticule also known as a graticule, is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight, spotting scope, theodolite, optical microscope or the screen of an oscilloscope, to provide measurement references during visual inspections. The lower right represents a reticle found in the PSO-1 scope of a Russian SVD designated marksman rifle. crosshairs A comparison of different reticles used in telescopic sights. Watch the video above to learn exactly why having a reticle keeps you from losing your lunch.Aim markings in optical devices, e.g. In fact, the creators of Mirror’s Edge actually consulted with ballerinas to figure out how they do eight spins in a row without vomiting all over the front seats. It’s the same theory behind spotting, a technique where a dancer will keep their eyes trained on one spot as their body executes full spins. That freckle is a constant, unmoving point on the screen, a place to focus when your avatar is in motion. If you’ve ever circled back to those early first-person shooters, you might’ve experienced the Gamer’s Sour Curse: motion sickness. It’s so common we rarely have to think about what information we’re getting from that little dot on our screen.Īnd that’s not even the best service the reticle provides. Now the reticle is used as a vehicle for all sorts of information, like when you’re hovering over an enemy, what gun you have equipped, and whether you can interact with an object. Outside of Halo, which arguably perfected the crosshair in 2001, first-person shooters generally didn’t get wise to using the reticle as a form of communication until the mid-2000s. A lot of the early FPS games, like Doom (1993) and Goldeneye (1997) didn’t bother with one. Using a reticle to communicate gameplay information is pretty standard now, but it’s a feature that a whole generation of first-person shooters just forgot about, when they had a reticle at all. Battle Zone (1980) featured a legit, stationary aiming reticle, which I mention because the reticle was dynamic it changed when you hovered over an enemy. Our pixelated friend showed up early in arcades, mostly in submarine games, like Sea Wolf (1976), and later on in light gun games like Sega’s Jurassic Park (1994). ![]() Sure, it helps you aim, but the reticle has other incredibly important purposes that are easy to take for granted. The reticle is that little dot, crosshairs, or aiming circle on your screen that’s so common you might not have thought much about it. ![]()
