This goes far beyond washing hands Apple's newly discovered patent suggests that the company is looking to scan veins in the wrist and hand as a way to detect gestures other than touch

Apple Insider found a patent application dated August 2018 named "Vein scanning device for automatic gesture and finger recognition" In other words, the watch would record images of the wearer's wrist as they move their hands to perform various gestures

Currently, Apple smartwatches have optical heart rate sensors and infrared sensors that can scan veins for heart rate, etc, but the patent indicates that additional sensors would be needed on the watch band itself to capture what the veins are doing on the back side of the wrist It indicates that

While there are only rumors about what features the Apple Watch 6 will have, there is no speculation pointing to vein tracking as a way to register gestures However, given Apple's interest in augmented reality, gesture control could be used in conjunction with Apple's AR glasses

Touchless gestures could also be useful in other applications, such as for people with mobility issues or for interpreting sign language gestures

From fall detection to atrial fibrillation detection, Apple has recently been ahead of the curve when it comes to adding sensors and health features to its smartwatches

Touchless gesture control has also been tried with limited success in other mobile devices such as smartphones Some drones can also be controlled using only hand gestures Thus, it remains to be seen what will happen with this patent from Apple
