Apple Watch Series 4: This is why the device is useful for elderly, youth

If you are constantly worried about an elderly person in your family suffering a fall in the bathroom or in the garden, the Apple Watch Series 4 is what you need.

Being utilised the world over for various health-related research - from decoding binge-eating disorder to connecting hip and knee patients to doctors - the new Apple Watch houses a feature called "Fall Detection" that will alert emergency contacts saved in your iPhone in case you meet with a hard fall - in the restroom or outdoors while performing routine activities. A timely response will not only save lives but also minimise the consequences.

In Series 4, the next-generation accelerometre and gyroscope are more powerful. Custom algorithms use data from both sensors to analyse wrist trajectory and impact acceleration, so that the Apple Watch can determine if and when a hard fall has occurred.

When an incident like this occurs, a hard fall alert is delivered to the Watch, and you can easily initiate a call to emergency services or dismiss the alert. If Apple Watch detects you have remained motionless for one minute, an emergency call will be placed automatically and a message with your location will be sent to your emergency contacts. The feature is automatically enabled for users over age 65.

Apple Watch Series 4 is now available in India -- the GPS+Cellular variant starts from Rs 49,900 and GPS-only model from Rs 40,900. When it comes to design, the display of new Watch is over 30 per cent larger than the previous S3 generation, introducing a new technology called low-temperature polycrystalline oxide (LTPO) for better power efficiency.

The back of the Series 4 models is made entirely of black ceramic and sapphire crystal for improved cellular reception. The Series 4 comes in two sizes: 40mm and 44mm. The cases are just slightly taller and a bit wider but thinner, making them smaller in volume.

With the GPS+Cellular model, you can make calls, reply to messages, stream Apple Music and Apple Podcasts -- even when you`re away from your iPhone. Jio and Airtel are the two carriers who provide cellular connection for the new Watch. The user interface and apps have been redesigned and optimised for the new display. Text is larger, so it`s easier to read; buttons are bigger so are easier to tap.

Apps like Maps and Photos now go edge to edge so you see more on the larger display. The watchOS 5 brings innovative features like automatic workout detection, Activity Competitions, Walkie-Talkie and more. When it comes to health, the new Watch has and electrical heart sensor with two new features -- low heart rate notifications and faster heart rate reading.

The moment you get furious -- in office or at home -- Watch Series 4 sends you an immediate notification about your heart rate going through the roof, requiring you to cool down. Notifications for low heart rate could be a sign of a serious health condition. The optical heart sensor checks in the background and alerts you if it detects a heart rate that is below a specified threshold for 10 minutes.

The electrical heart sensor is also capable of taking an electrocardiogram (ECG) using the ECG app, which will be available in the US later this year as the Food and Drug Administration (FDA) has approved it. Apple will bring this feature to more countries, including India, once the necessary approvals from relevant stakeholders and regulators are granted.

The 10.7mm thin (Series 3 was 11.4mm thin) S4 Watch has 64-bit dual-core S4 processor which is up to two times faster than the S3 (which had Dual-core S3 processor). The 16GB Watch is water resistant up to 50 metres, comes with W3 Apple wireless chip, and has built-in rechargeable lithium-ion battery that gave nearly day-long power.

The speaker is 50 per cent louder than the previous generation and the new mic location reduces echo for clearer phone calls. Apple has also made sure your health and fitness data is secure with the S4 Watch and is encrypted on devices and in iCloud.
