9. A system, comprising:
a camera;
a memory storing instructions;
a processor coupled to the memory and configured by the instructions to at least:
obtain, with the camera, an image depicting a hand at an initial zoom scale;
estimate a pose of the hand depicted in the image;
determine a distance between the hand and the camera of the system;
adjust the zoom scale based on the distance between the hand and the camera of the system, wherein adjusting the zoom scale based on the distance between the hand and the camera comprises adjusting the zoom scale to be inversely proportional to the distance between the hand and the camera;
generate a modified image by cropping the image according to the adjusted zoom scale;
render an augmented reality object on the hand depicted in the modified image according to the adjusted zoom scale and the pose of the hand depicted in the image; and
display the modified image with the rendered augmented reality object.
