What You'll Learn
Hawk-Eye technology for tracking shuttlecocks
Badminton has embraced technology in various ways, and one of the most notable is the adoption of Hawk-Eye technology. This system was introduced by the Badminton World Federation (BWF) in 2014 to bring greater accuracy and clarity to the sport.
Hawk-Eye is a computer system that uses multiple high-performance cameras to track the shuttlecock from different angles. The cameras are typically positioned on the underside of the stadium roof. The video footage from these cameras is then combined and triangulated to create a three-dimensional representation of the shuttlecock's trajectory. This technology is not just limited to badminton; it is also used in sports such as tennis, cricket, and football.
The Hawk-Eye system provides several benefits to badminton officials and the sport as a whole. Firstly, it offers an impartial review system for line calls, helping to eliminate errors in judging whether a shuttlecock landed in or out. Secondly, it provides valuable data and insights, such as shuttlecock speed, which can be used to analyse player performance and make strategic decisions. The system can also be used for instant replays, allowing officials and viewers to review controversial moments and gain a better understanding of the game.
One of the key advantages of Hawk-Eye is its accuracy. The system is advertised to be accurate within a range of 2.6 to 3.6 millimetres, which is an extraordinarily precise margin of error. This level of precision helps to ensure fair and consistent decision-making in the sport. However, it's important to note that Hawk-Eye is not infallible, and there have been instances where its accuracy has been questioned, such as the 2007 Wimbledon Championships, where a shot was called in by Hawk-Eye even though it appeared to be out.
Overall, Hawk-Eye technology has revolutionized badminton by providing officials with an advanced tool for tracking shuttlecocks, enhancing decision-making accuracy, and improving the viewing experience for fans. It has become an integral part of the sport, contributing to its integrity and excitement.

SMART Replay technology for reviewing infringements
Badminton is a sport that has embraced technology to enhance performance and popularity. One of the key technologies adopted by badminton officials is SMART Replay technology, which has revolutionised the way infringements are reviewed and decisions are made during matches. SMART Replay technology is an innovative tool that provides ultra-high-definition video footage, allowing officials to review contentious situations and make informed decisions. This technology has brought a new level of accuracy and fairness to the sport.
SMART Replay technology involves the use of multiple high-definition cameras positioned strategically around the court. These cameras capture the action from various angles, ensuring that every shot, movement, and potential infringement is recorded. The footage is then instantly available for review by officials, who can analyse the play from different perspectives to gain a clear understanding of what occurred. This multi-angle review capability is particularly useful in identifying infringements, such as footwork errors or shuttlecock trajectory disputes.
One of the standout features of SMART Replay technology is its ability to provide super slow-motion replays and freeze-frame capabilities. This functionality allows officials to scrutinise critical moments in minute detail. For example, in close line calls, the technology enables officials to freeze-frame the exact moment of shuttlecock impact, ensuring accurate judgement. The super slow-motion replays also help in reviewing instances of potential foul play or unsportsmanlike conduct, ensuring that any penalties or disciplinary actions are warranted and justified.
The introduction of SMART Replay technology has brought numerous benefits to the sport. Firstly, it has improved the accuracy of decision-making, reducing the likelihood of human error in judgement calls. This technology ensures that outcomes are based on factual evidence, enhancing the integrity of the sport. Secondly, SMART Replay technology has enhanced the spectator experience, providing thrilling replays and a clearer understanding of the game. Finally, this technology has contributed to the development of badminton players and coaches, offering a valuable learning tool to analyse performance, identify areas for improvement, and devise targeted training strategies.

Electronic or manual scoring systems
Badminton officials use a range of technology to help them officiate matches. The most notable is Hawk-Eye, a Sony-owned computer vision system that was introduced by the Badminton World Federation (BWF) in 2014. Hawk-Eye uses several cameras to track the trajectory of the shuttlecock and record its position at various points, providing a three-dimensional profile. This allows officials to review disputed calls and make more accurate decisions. The technology also enhances broadcasts by providing additional data, such as shuttle speed.
While Hawk-Eye is a valuable tool, it is not perfect and officials still need to use their judgement when officiating high-stakes games. In the case of minor tournaments, it is less common for standard officials to be hired, and line and service judges may not be present. This is due to limited prize or sponsorship money.
In terms of equipment, badminton officials typically have a uniform provided by tournament coordinators and sponsors. They also usually supply the players' equipment. Essential hardware for officiating a badminton game includes a watch with a timer, caution cards, a clipboard, a scorecard and pen, and an official chair of a specified height.
The use of electronic or manual scoring systems is also important for badminton officials. The BWF recommends the use of an electronic scoreboard, but a manual scoring system can also be used and should be placed to one side of the umpire's chair.

Standardised clothing and equipment
Badminton players also have standardised clothing and equipment requirements. Competitive players are required to wear shorts and short-sleeved shirts, with their names printed on the back for Olympic competitions. In doubles matches, partners must wear the same colour uniform, which must be distinct from their opponents. Additionally, players should wear badminton shoes, which provide better traction and grip, as well as cushioning for jumping and landing.
Players also require essential gear and equipment for a successful badminton game. This includes the badminton racket, which can be made from various materials, including wood, aluminium, graphite, or titanium. Rackets typically weigh between 3 and 3.5 ounces and feature synthetic threads that form a uniform string pattern. The shuttlecock, also known as the birdie, is another essential piece of equipment. It is made with a cork-rounded base and synthetic duck or goose feathers. Plastic shuttlecocks are more durable than their feathered counterparts.
To enhance their performance, players can utilise smart gadgets such as smartwatches and wristbands to monitor their movements, calories expended, and even badminton strokes. Innovative court systems with cameras and pressure sensors also provide valuable data on player movement and shuttlecock trajectory.
