(MENAFN- The Conversation) Gabriel Jesus's disallowed goal in the English Premier League,between his club Manchester City and Spurs , when a controversial handball decision was given by the video assistant referee (VAR) system, has fuelled the already fierce debate about the use of technology.
The handball law waschanged in March 2019due, in part, to the use of VAR. The new rule said a handball that gave advantage to the player handling the ball would be penalised – even if it was accidental. Previously the law had given the referee the discretion to rule on whether a handball was accidental. Use of technology effectively removed the officials' ability to use their discretion. Jesus'shandball was one of those situations .

Video Assistant Referee: in football, as in war, sometimes we need a human touch
VAR has already become a big talking point in top-flight football after the same City player had a goal disallowed in the first round when his team took on West Ham, this time over amarginal offside decision .
This has led football's law makers to review the approach taken to offside decisions. The officials should call offside only if there is a ' clear error '. Andthere are questionsover whether the technology is accurate enough to be able to measure offside to such a degree.
Football has followed the trend of other sports that have already adopted technology. Rugby league provided avideo referee in 1996 . Cricket included theHawk-eye ball tracking system from 2001 . Rugby union introduced theTelevision Match Official (TMO)in 2001. Andtennis began using Hawk-eye in 2002to judge line calls.
They think it's all over
The introduction of any technology can mean that the experience of spectators changes – and not necessarily for the better. Technologyreduces errors , which is of vital importance in today's big-money sporting contests. But it also means a goal can be scored, celebrated and then disallowed, meaning that spectators at the stadium do not act spontaneously. Instead of being able to jump up and down in delight at their team scoring or taking a wicket, they have to wait on technology. It's just not the same.
Another criticism is that spectators oftendo not know what is happening on the pitchwhen VAR is being used. The use of big screens in the stadiums to replay VAR decisions has been approved for the 2019-2020 Premier League season, displaying the incident to supportersto help them understandwhat is going on. But criticisms of the process continue and it is still to be decided whether spectators should beshown the entire VAR decision-making process .
At home, spectators have the benefit of technology. There are more camera angles, sharper pictures, and the benefit that any VAR review is immediately communicated and explained. As theBBC noted , people are beginning to wonder whether it's not better to save money and stay at home to watch on television. That would be a disaster.
Players behaving badly
We know that changes in the interpretations of law between countries canchange the behaviourof both officials and players. It's too early to tell how VAR will change how football works, but we do know that technology has changed player behaviour in cricket.
The decision review system (DRS) was introduced in 2001, aimed at improving decision-making accuracy for catches, and enhanced in 2008 in order to detectleg-before-wicket(when a batter's leg stops the ball hitting the stumps). Teams are now using their reviews tactically, which can change the rhythm of a game and interrupt a batter's concentration – surely not within thespirit of the game .
There have also been incidents of player behaviour influencing the removal of technology. Hotspot is an infrared imaging system used to show whether a ball had struck a batsmen, bat or pad. But it was taken out of the DRS after it was shown that placing tapealong the edge of the batcould fool the thermal imaging cameras that were there to detect the heat created by the friction when a ball hits a bat, no matter how slightly.
Umpires are only human
Technology can also put pressure on match officials, which can contribute to negative performances. The first 2019 Ashes test match between England and Australia saw a number of on-field umpire decisions overturnedfollowing use of DRS .
Umpires stand for up to five days during a test match, and so a number of incorrect decisions can build pressure over the course of the game. This is increased by the umpire knowing that their decision can be challenged and overturned using technology at any moment.
Pressure for cricket umpires comes, at least in part, from media exposure and the use of technology in the game. This is also true for football referees who are exposed to extensive media coverage.
Level playing field
It's hard enough for officials to do their jobs properly with the pressures outlined above. But then take into account that different sports in different countries are having to contend with variations in the way technology is applied. (See, for example, the controversy overgoalkeepers moving off their linewhen a penalty is taken.)
There is big money at stake in professional sport, and careers can hinge on a key decision. So sporting administrators need to be careful about the impact any changes to their sports have on the live and televised 'product', sold in TV rights deals for millions of pounds around the world. If supporters stop watching, if television companies stop paying, they have a major problem. With technology, sometimes it seems we need to be careful what we wish for.
