New Devices Help Track Olympic Winners 209

Posted by timothy from the track-more-gymnasts-please dept.
Darren writes "Athletes are going faster, higher and longer and as a result the technology that measures their feats at the Olympics needs to keep up. As a result a number of new devices to help track winners, losers at the Games have been developed, including microchips on marathon runners' shoes, ultrasensitive touch pads in the pool, radar guns at the beach volleyball and cameras that take 1000 images per second."

    Putting RFID chips on your shoes is nothing new. All of the local races down here use ChampionChip [championchip.com] timing, unless they're really small. Have done for years, too. There's a local company, Run-Far [run-far.com] who times most of the races as well - you run over mats at the start, finish, and useful places in the middle. Works pretty well.

      Actually other then the fact that the fencing equipment in the olympics is wireless, there isn't much new to the electronic sensors. Fencing was one of the first sports to benefit from electronics due to the extreme speed of the action (sabre fencing is the fastest martial art in the world).

      Even with the sensors, an extremely skilled judge (called a director in fencing) is required to determine which competitor is considered the agressor and has 'right-of-way' to see who gets the point.

      On a side note, as a long time fencer actually getting to watch the sport in the olympics for the first time I realised one thing. It is a really bad spectator sport if you do not know the sport yourself. I watched the events on tv with family and friends and unless they showed a slow motion replay, people were just at a loss as to what happened (unless they were fencers themselves).

      And if the finish is that close, reviewing the photo would be in order.

    Would it not be better to put the microchip in the athlete number on the chest of the athelete? I am concerned that (assuming they only have one chip each in one shoe) one runner will have their left foot forward while the other has their right foot forward and the end of a very close race.

    Unless of course they have a chip in both shoes which would totally invalidate my problems with it. Are you suggesting I didn't read the article?

      If they had a chip in the shoe, it would be for tracking them in long runs, like the Marathon, or the 20 Km and 50 Km Race Walk.

      The rules say the torso is the body part that stops the clock and determines the winner, not the head, arms or LEGS, making it unusable to put them in the shoes. Maybe the front of the shoulder or in the number id for each athlete.

      And there's the issue of the scanning speed, also, as mentioned elsewhere.

    (I realize that kind of technology is far away, but at this rate, we've got no choice but to continue to invest more and more money to catch these "athletes")

    touch pads used in swimming have been capable of going further than the "required" level. times are only used down to the hundredth of a second though technology has existed to measure down to the thousandth.

    once upon a time, events were measured down to the thousandth. in one race, 400 meter IM about 30 years ago i believe, the time separating the winner to the runner up was 0.003 seconds - about 3 millimeters. after that, it was argued that the variation in the flatness of the touch pad/pool wall would

    The coolest tech out there is definitely finishlynx. It takes pictures of who crosses the finish line only a pixel or two wide and stitches them together so you know exactly who crossed the line in what order and what their times were since the times are exactly proportional with the pics. In this pic of me in the men's lightweight single dash [boathouserow.org] I am finishing 3rd (Alex Krupp, lane 1). The reason I appear so bloated compared to everyone else is I put on a huge fucking sprint at the finish and even though I was a full boat length of open water down on 5th place with 100 meters left I managed to finish 3rd. Not bad for not eating shit or drinking much in 2 days to make weight. Anyway because I was going so much faster than everyone else at the finish I appear in the least number of pixel wide images, thus making me appear bloated and compressed compared to all the other boats. The reason all the oars are swirly is because they change positions from when the first part of the oar crosses the line to when the whole boat is passed, thus creating a cool real time motion blur.
    • The technology is not exlusive to FinishLynx: TimeTronics uses the same technology [timetronics.be].

      And as I explained in another post, the analog version of finish photo, giving about the same result, has been used for decades.
  • I'll admit that the Olympics have some pretty cool devices to measure speed and performance (as well as to detect who is cheating).

    I also have to wonder about why these devices are developed. I know that this is a sort of "If they can put a man on the moon why can't they..." type of arguement (but) why are people so willing to develop things for entertainment - and sports is entertainment (even the olympics) when there never seems to be enough money for developing technology that will help the poor or tre

    your article on Digital photofinish timing info is slighlty incorrect. Most FAT (fully automatic timing) systems used at anything above a college meet will do 2000 lines/sec like the camera I own. Thats not to say that they aren't using only 1000 of them, just not likely.

    It would be good to see these in the shoes of the "50km walk" participants, to detect cheating. TV cameras repeatedly show snapshots of people with both feet in the air (the regulations of the sport are that you must have 1 in contact with the ground at all times). I predict that if this technology came through, the race times would increase by 15%

    I find that the closeness of the swimming competitions--in that only machines can judge who is the second place person and the third place person, make the competition seem a bit on the irrelevant side. Am I the only person who wonders what the hell the difference is between a Gold and a Silver if there were only 1/100 difference in the competitor's performances?

  • including microchips on marathon runners' shoes, ultrasensitive touch pads in the pool, radar guns at the beach volleyball and cameras that take 1000 images per second

    It'd be nice if we could throw a little technology at improving the judging in gymnastics. The athletes deserve a lot more fairness than they got this year.

    Perhaps we should start by locating a guillotine on the podium, where it might serve as a constant reminder to the judges.
