The patent also explains how sensors could be used in a smart band to analyze sport performance in sports such as football, baseball, and golf.
Originally made in September 2017, the patent application was granted today.
The main focus is on the smart band, which explains how sensors can be used to coach sports. For example, in baseball or golf, strain gauges could be used to analyze the grip, and the swing was analyzed using accelerometers and barometric sensors.
But the patent also refers to cameras being included in the face of the Watch. It describes things like barcode capturing or QR code capture, but also user images. It is possible to use the selfie camera(s) for video calls or Face ID.
In addition, today’s publication echoes an earlier Apple Watch patent that explains how sensors could be used in a smart band to recognize and authenticate the user through something we might call “Wrist ID.”
