To buy Apple Watch you can measure your pulse in AR. How to buy an Apple Watch with the right size band without having ever worn it? At the moment Apple allows you to print a model on paper to try on your wrist, but in the future there may be a better solution.
All the Apple iPhone 14 rumors: will the new iPhone have satellite telephony?
In fact, a patent has recently appeared entitled Contactless Pulse Measurement that uses Augmented Reality technologies to make a more precise measurement. It reads in the documentation:
Currently existing measurement techniques have several disadvantages, such as the use of special equipment. Above all, they require contact with the person’s wrist, and in addition to being bulky, they can also be subject to errors.
The system uses a depth sensor scanner and it is easy to expect this device to be the iPhone itself, with its LiDAR system. In practice, the device is placed on a flat surface with the scanner facing upwards and the user has to do is place his hand at about a palm in height from the device and rotate the wrist 90 degrees to allow the system to create an in-depth mapping of the wrist.
The images collected during this process are sufficient – they explain – to accurately represent the circumference of the wrist and obtain a very precise measurement, in order to then carefully recommend the right size for the strap.
Such a system could thus make purchasing Apple Watch remotely even more relaxing because the chances of buying the right strap increase exponentially. Especially since Apple already offers an infinite number of straps of different materials and sizes, and in the future it is likely that the catalog will be expanded even more.
The patent is credited to six inventors and four of these have previously worked on the AR measurement technologies of the Metro app.
