thinking on the context of character and movement, I wanted to test out this latest sdk I got my hands on which uses only a single camera feed to detect the pose.
Play can be referred to terms such as tinkering and technological play, while stillness would be minimum equipment usage. Generally, pose estimation requires something external such as xbox Kinect or etc. but this sdk only uses a single camera and AI to do so, it can run on IOS phones and on laptops or pc as well without external hardware.
A pro is that as a user, it doesn't require external hardware, this can be used for general installations, games and great mobile apps, though con is it cannot detect depth. that means user cannot move front and back(as of now and what I understood from the sdk).
