Infrared Drowning Detection System To Be Installed At 11 Public Swimming Pools In Singapore (channelnewsasia.com) 34

By April 2020, a total of 11 public pools in Singapore will feature a state-of-the-art computer vision drowning detection system (CVDDS). The CVDDS uses a network of overhead infrared cameras to detect if anyone in the pool becomes unconscious while swimming. It reportedly has a detect response time of 15 seconds, allowing lifeguards to spot distressed swimmers more quickly.

"[T]he system will be installed at pools in Bukit Batok, Jurong West and Our Tampines Hub this year, with another seven to follow by April 2020," reports Channel NewsAsia. "The system will be implemented following a successful year-long trial at Hougang Swimming Complex. MCCY said that the system was assessed to have complied with international standards and had a low false-alarm rate."

    In Europe public pools have been forced to install these years ago.

      While such automatic camera/alarm systems are installed in some pools in Europe, there is no legislation making this a requirement. In Germany, the first two such systems were installed in 2005, so indeed, the technology itself isn't quite new.

      Nope. Have never encountered them. But then again, I'm in the Netherlands where everybody can swim so only foreigners drown :p

      • What are you talking about, plenty of dutch people drown ... intoxicated ... after a night drinking Belgian strong ales ... and then falling into a canal.

      • I was at a pool in Belgium and a kid got into trouble. They either didn't have this system or it's slower than a human, because no alarm went off but the instructor spotted it in pretty short order and rescued him.

  • I'm curious what that means? Did they fire all the lifeguards, or wait for people to become unconscious?

      Its a machine vision system that tracks movement in the water. Stop moving long enough and the computer sees it and triggers the alarm. Its part of an 'overmind' design. Humans become inattentive over time, so we are going to gird up those jobs with 'intelligence'.
      • As a kid I would have had a blast fucking with a system like this. I used to love to dive to the bottom of the pool and sit there as long as I could. Freaked out my family more than a few times doing that.

          Anyone doing apnea training would need some kind of special exemption.

            I'm sure they won't be training when the general public is out and playing in the pool where a lifeguard already has a hard enough time trying to see if there's someone in distress.

            They'll either use a private pool, or close the pool at which point they can ask for the system to be disabled because well, there's more oversight.

    It's a potentially effective tool, but will it encourage complacency? Will lifeguards pay less attention, or pools' management choose to staff less lifeguards? Will parents put less emphasis on water safety? What is the false-negative rate (real events it doesn't detect)? Does the system have an obvious fail-safe indicator if it isn't functioning?

    • Yes, it will encourage complacency. Yes lifeguards will pay less attention. Yes less lifeguards will be staffed. Yes parents will put less emphasis on water safety.
      These are good things, and here's why. It's automation done right. Right now, a lifeguard's job is to watch over pools and readily respond to emergencies and render aid. If a computer can do the job of watching the pool much better than we can, the job of a lifeguard can just hang out and be ready to respond to someone drowning and fish them out

Hackers are just a migratory lifeform with a tropism for computers.
