I would like to congratulate the author on this paper. It was much developed compared to the abstract.
Content is comprehensive and the experiment is interesting.
I would like to see more figures and screen shots to elaborate on the experiment.

Certain quotes were not properly referenced, particularly with Sutherland and Hortsmann. I expected page numbers.
Since this paper is going to be published in black and white, it would be wise to include figures with high contrast and shades of grey especially when there is a comparison.
