1. An information handling system comprising:

  • a first digital camera that is an RGB digital camera to capture a first image;

    a second digital camera to contemporaneously capture a second image;

    a processor operatively coupled to the first digital camera and the second digital camera;

    the processor executing code instructions of a gross-level input detection system to detect at least one object in each of the first image and the second image using object detection techniques and to normalize the first image and the second image in comparison to one another with respect to differences in horizontal and vertical pixel coordinate locations between first digital camera parameters and second digital camera parameters reflected in the first image and the second image;

    the processor executing code instructions of a gross-level input detection system to further identify a region of interest within the at least one object in each of the first image and the second image and calculate a gross-level three-dimensional position of the region of interest within the at least one object in each of the first image and the second image by comparing differences between normalized pixel coordinates of the region of interest within the at least one object in each of the first image and the second image to determine orientation and position of the region of interest of the at least one object; and

    the processor to receive a user input command for execution on the information handling system determined from the orientation and position of the region of interest of the detected at least one object.
