so last I checked we're a tech Channel
but for some reason there's been a long time ongoing argument in our comment
section about whether it's football or
soccer well whichever side of the argument you're on and our writer John
would like to gently remind everyone that both are perfectly legitimate names
for the sport something that should interest all fans of association
football also correct by the way is the recent surge in popularity of goal line
technology so for those less familiar with the sport you're probably wondering
how hard is it to tell when the ball goes into the goal we need tech for
this actually it's a pretty frequent
occurrence where the ball seems to just
barely cross the goal line if for example the goalkeeper tries to save it
while he is basically on the line or if
it hits off the crossbar and bounces downward as in the 1966 World Cup final
and since the ball has to be completely
across the line to count this decision can often come down to literal
millimeters meaning that referees won't always be able to get it right on their
own go line technology seeks to remove
this uncertainty with systems that are more sophisticated ated than mere
instant replay in fact the systems
currently used for major European and
international matches use not just one
but 14 different cameras with seven pointed
at each goal and the way it works is
really cool every camera is connected to
a computer which can compare both the
ball and the pitch that's the field to a
3D bottle allowing the system to
triangulate the position of the ball at any given moment and even if multiple
cameras have their view of the ball blocked by something like a big group of
players scrambling in front of the goal the system can still work since only
three of the seven cameras are needed at a time to determine where the ball is in
3D space if the system recognizes that
the ball has completely crossed the goal line it will will send a signal to a
special wristwatch worn by the referee to indicate that a goal should be given
because this system relies entirely on computer analysis it allows the referee
to rule goal or no goal almost
immediately instead of Performing the lengthy video reviews similar to what
you'd see in sports like American football and ice hockey and because
these cameras are extremely sophisticated I mean we're talking as
high as 500 frames per second goal line
technology can be accurate to under 4 mm
to demonstrate check out how close this
call was during a 2016 match between
Bournemouth and liver poool and even though the powers that be were hesitant
to introduce it after a number of high-profile referee blunders this kind
of camera- based goal line technology is now being used in these Major Leagues
non-domestic competitions like the UFA champions league and Copa America have
also embraced the technology and it was also used at the World Cup for the first
time in 2014 and will be again at next year's World Cup in Russia but there's
also a competing method that doesn't rely on cameras involving magnetic
sensors that are embedded into the goal frame or even underneath the grass and a
circuit that gets inserted into the ball itself self this system can determine
when the ball enters the goal by measuring changes in the magnetic field
it's less expensive than the high-speed camera scheme used by the big money
competitions so you may see it become more common at lower levels of the game
over time but there are likely to be
concerns among players at the highest here about any modification to the
standard ball and although purists of
the sport have opposed the integration of technology in general baseball is a
prime example of this claiming that human error is part of the game the
current Trend does seem to be toward ensuring that goal calls on the pitch
are correct especially with influential
Mega clubs like Barcelona calling for the technology to be introduced in Spain
so are you a soccer/football fan with an
opinion one way or the other on goal line technology or heck maybe you have a
comment about another Sports use of similar technology let us know how you
feel in the comments and also tell us if you'd like to see more Tekken sports
videos in the future I mean maybe we could even come up with a techie
solution to help the Canadian national team improve its game
or I guess the other option is uh we could just stick to
hockey tunnel bear VPN lets you tunnel
to one of plenty different countries allowing you to browse the internet and
use online services like video streaming
services as though you are in a different country it is a great way to
get access to content that's behind pesky Geo restrictions they have easy to
use apps for iOS iOS Android PC and Mac they also
have a Chrome extension and it is so simple to use that there is just no
excuse for for not encrypting your connection and hiding from advertisers
and your ISP or anyone who wants to spy on what you're doing online your
activities you just press pretty much one button and boom you are anonymized
and you can choose whichever country you want to appear as though you are
browsing from so try out tunnel bear VPN with 500 Megs of free data at the link
below and if you choose to get a year of unlimited data which probably should you
