Method and system for controlling point spread of an object

Abstract

A method of controlling a point spread of an object is disclosed. The method includes determining a first value of a characteristic of an optical component of a display, wherein the display includes a first display screen and a second display screen, and wherein the first and second display screens overlap. The method also includes determining a position for the optical component based upon the first value of the characteristic by determining a distance from an origin of the object to the position based upon the first value of the characteristic.
