How to download a digital speedometer in a smartphone app
Posted March 14, 2019 08:00:15A smartphone app may be the easiest way to find your digital speed, but the speedometer itself may not be that simple.
According to a new study, smartphone apps are making it more difficult to find the correct digital speed.
The National Association of Broadcasters says the number of apps using the same code for a digital clock is increasing.
The app makers, however, claim the numbers are a result of the app being updated to support digital clocks.
The Association of American Publishers says it is worried that apps are using the speed of smartphones to generate a false sense of speed.
“If an app is updating a speedometer, they’re really, really doing the wrong thing,” said David Menn, publisher of the online magazine Science, in an interview with CBC News.
He said there is a need for apps to keep pace with technology.
“We’re not talking about the speedometers and speed meters,” he said.
“You can’t just have an app update the speed or the location of a clock.”
In Canada, there are a number of smartphone apps that use the GPS, but Menn says these apps aren’t using GPS coordinates as a source of speed data.
“I would argue that the GPS should be used as the reference for what speed to look at, rather than as a speed-calculator,” he told CBC News in an email.
“It’s a good analogy to look for the GPS to determine what speed you’re driving at.”
The Association for Computing Machinery (ACM) recommends that apps use the actual time of day, and not just the time at which the app is installed.
ACM said the use of digital clocks could also lead to confusion, as users could look at an app and see it had been updated for the digital clock.
The association is not the only one to be concerned about digital clocks, as there are concerns that app makers are using GPS to generate speed data that isn’t accurate.
The CBC News investigation found a number the apps use GPS coordinates to generate their speed data, but that speed is not measured in metres per second.
The app makers said they use a formula that uses real-time GPS data to calculate speed, and that’s why there are no errors.
But ACM’s Menn said he is concerned that speed data may be being used to generate false data.
The ACM says there are numerous ways to accurately calculate speed.
The association says the formula can be used to determine the speed for a vehicle, a bike, a motorbike, a jet ski, a canoe, a hovercraft, and a watercraft.
“There are lots of ways to calculate speeds and there’s no single way to calculate it,” he explained.
“The fact that there are so many different ways to estimate the speed in the real world, is a very real concern.”CBC News has contacted both the Association for Broadcasters and the Association of the Motion Picture and Television Producers for comment.
