Interestingly, Apple had filed a patent in 2016, which was later granted in 2020, that describes this technology employed by the Apple Vision Pro. Although the original patent link is no longer accessible, AppleInsider previously covered its contents. The patent discusses the natural human interaction of touch and the widespread use of touch screens in devices like smartphones and tablets. Apple’s scientists explored the idea of using cameras to track finger movements and enable touch interactions—a concept now realized with Vision Pro.
