Usually, an Apple Watch user manually tightens the wrist watch’s strap on his/her wrist. However, this changes from time to time depending on weight gain, but it seems that in the future, the Apple Watch could tighten itself based on how loose or tight the device is on the wearer’s wrist.
This means that over time as you gain or lose weight, your watch could automatically adjust its tightness so you don’t have to do it yourself. So how does the watch know that it might need some tightening? According to the patent, it mentions how it checks the watch’s tightness against the operational tolerances of the health sensor.
According to Apple,
The processing unit determines a tightness of the band based on the signal and perform one or more actions based thereon. Such actions may include evaluating the signal for changes in the tightness of the band according to operational tolerances of the health sensor, providing output directing the user to adjust the band to improve operation of the health sensor, monitoring changes in the tightness of the band and adjusting a measurement obtained by the health sensor, and so on.
It’s an intriguing patent even though it looks like a cumbersome one. However, it could result in an Apple Watch that will offer up the most comfortable fit possible for the wearer, although it is imagined that such an Apple Watch and an automated band could prove to be expensive.
