1. A method for visual indication of suture strain comprising:
detecting a force applied to a suture by a laparoscopic instrument configured to place the suture;
obtaining an image, the image including the suture;
identifying a color associated with the force applied to the suture based on at least one of:
an algorithm to convert a plurality of forces to a plurality of colors; or
in a table that associates a plurality of colors to a plurality of forces, respectively;
generating an augmented version of the image wherein the identified color is used to represent and overlay at least a portion of the suture; and
displaying the augmented version of the image including displaying a legend indicating how color corresponds to force.
