So what does this mean for end users? Like we said, it does help to bring touchless gestures to Apple’s devices. One example that Apple has given is in the form of exercise apps, where with the updated Vision framework, it will be able to track the exercises that the user is performing and could then help them correct their poses.
It can also be used in safety-training apps to help encourage correct ergonomics, as well as media editing apps where it can help users to find images or photos with a specific pose that you have in mind. Users will also, in theory, be able to interact with their mobile devices by holding out a hand pose to trigger the camera’s shutter.
It can also be used in more novel ways where you could hold a hand pose and it will try to see for an appropriate emoji to overlay it (like the OK gesture or the peace sign). The onus here seems to be largely on developers taking advantage of the Vision framework, so your mileage may vary depending on the apps that you are using.
