"What's interesting about these features is the extent to which they rely on on-device artificial intelligence to work. The hypertension detection tool, for example, relies on photoplethysmography (PPG) data, gathered over time by shining light into the skin and measuring the light reflected in return. This information feeds an algorithm (developed across 100,000 study participants) that identifies whether you are at risk, then lets you know."
"Once upon a time, horses had horns, illness crept upon us, treatments were based on superstition, and lives were short. My, how things have changed. Today, you can be warned of early signs of sickness by your smartphone and other wearable devices, including the Apple Watch and ( more recently) AirPods. Apple has updated those two latter products, enhancing their existing health-focused tools with hypertension detection/alerts on the watch and heart rate-sensing on AirPods 3."
"There are many other health-focused features on both devices that use AI to give you useful information. But what ties all of these tools and services together is their ambience. You see, rather than thrusting artificial intelligence in your face (even though it is quite literally putting AI inside your ears with those new AirPods), Apple is opting for an approach in which technology augments your daily life."
Modern smartphones and wearables can warn of early signs of sickness, including Apple Watch and AirPods. Apple updated those devices with hypertension detection/alerts on the Watch and heart-rate sensing on AirPods 3. Hypertension detection uses photoplethysmography (PPG) data gathered over time by shining light into the skin and measuring reflected light. That data feeds an algorithm developed across 100,000 study participants to identify risk. Many other health features on both devices use on-device AI to provide information. Apple emphasizes ambient AI that augments daily life and maintains connection to reality rather than isolating users in a tech bubble.
