Watch, including a new Dance workout type. In a new interview, Julz Arney
from Apple's Fitness Technologies as elaborated on what it took to develop
the Dance workout type with accurate calorie tracking and more.
In the Workouts app on <https://amzn.to/2ZYjDO1> Apple Watch, each of the
20 top-level workout types "uses a smartly-tuned algorithm that understands
the workout you are doing to give you the most accurate metrics for each
one," Arney explained to
<https://tech.hindustantimes.com/wearables/news/exclusive-inside-the-apple-w
atch-s-dance-tracking-algorithms-71594351776059.html> HT Tech. For this
reason, it was important that the new Dance workout type adheres to the same
standards.
The Workout app on Apple Watch is one of the most used apps, and each of the
20 top-level workout types uses a smartly-tuned algorithm that understands
the workout you are doing to give you the most accurate metrics for each
one," Julz Arney from Apple's Fitness Technologies team told HT Tech.
Apple faced several challenges during the creation of the Dance workout
algorithm, primarily because movements in dance aren't predictable or
repetitive:
"Creating an algorithm to give accurate calorie credit for dance was a real
challenge for a few reasons," Arney said. "Movements in dance aren't always
repetitive or predictable like they are in walking and running, so what the
sensors can detect strictly from the wrist is not necessarily the whole
story," she added. For dance, the watch needs to detect how your "whole body
is moving".
To track calories through the Dance workout type, Apple is using what it
calls "advanced sensor fusion." This combines data from the accelerometer
and gyroscope to "detect the difference between dancing with just your arms,
just your lower body, or when you dance with your entire body."

and a public beta should be available sometime this month.
