Leveraging sensor fusion, the hand-washing function in watchOS 7 is a welcome addition amid the coronavirus pandemic
So when watchOS 7 was launched at Apple’s ‘Time Flies’ Special Event on September 16, it not solely got here with sleep monitoring however it additionally launched a hand-washing timer. The function was first introduced at the digital Worldwide Developer Conference (WWDC) 2020 in June.
How it really works
Such a function has to have some sort of break-through innovation right here: Apple Watch makes use of movement sensors whereas its microphone and on-device Machine Learning to robotically detect hand-washing motions (sure wrist swivels) and sounds (water operating). By doing this, it robotically kicks off a 20-second timer (a time universally suggested by the World Health Organization and Centers for Disease Control and Prevention (CDC) motivating individuals to spend the correct period of time scrubbing to maintain their arms clear and shield their well being.
- For notably thorough hand-washing periods, it is value activating the Water Lock in order that there’s no display screen contact from falling droplets. After the hand-washing, it is value turning the crown to launch water that will have gotten into the system.
Essentially, by correlating the sounds of hand-washing with the actions of scrubbing, the system is capable of differentiate hand-washing from the different actions which require comparable hand actions that you just do in a day. For these comparable actions, Apple has recorded a number of examples of those and labeled them so the fashions may be taught the refined indicators that differentiate these examples from hand-washing itself.
The design of the hand-washing timer is fairly engaging too, with a bubble-foam font and timer for the countdown. If you aren’t washing your arms, you possibly can faucet the small ‘cancel’ choice on the Watch display screen. Those who cease washing their arms earlier than the timer get a normal message about the want to scrub for a full 20 seconds.
One may also entry the hand-washing knowledge by way of the Health app of their Watch-connected iPhone, to see how usually they’re washing their arms and if it is constant. This is introduced in infographics measured towards the targetted time so customers have an thought of what benchmark to satisfy.
So what is subsequent? Kevin Lynch, Apple’s Vice President of Technology, says, “Sensor fusion, used in the automatic hand-washing detection feature, is a technique that we’ve been using since our early days on Apple Watch, and it provides a rich view into different activities. We’re constantly looking for ways that we can combine the views from our multiple sensors or add new sensors that would provide perspectives that we don’t have yet.”
Hand-washing on watchOS 7 appropriate with Watch Series 3, four and 5, in addition to the Watch Series 6 and SE which come watchOS 7-ready.
