Techniques for determining a grip layout to improve gun ergonomics

A method of determining a grip layout for a gun, the method comprising:

• obtaining an image depicting a hand and a fiducial marker;
• performing object detection on the image to identify the hand and the fiducial marker within the image;
• performing annotation on the hand based on a machine learning model that has been trained with a first set of training data including multiple images containing hands, wherein each image of the multiple images of the first set of training data is annotated;
• and
• generating a measurement of the hand based on a second machine learning model that has been trained with a second set of training data including multiple images containing hands, wherein each image of the multiple images of the second set of training data is labeled with a measurement.
