James Mackenzie's Polygraph Essay

I would like my timeline to be very informational and provide the readers with a deeper understanding of how timelines through the ages have improved the quality and accuracy of the judicial and court system throughout the world. I also hope my timeline will express how the innovations from more than a hundred years ago shaped the society we see today.

In 1902, Doctor James Mackenzie a Scottish cardiologist invented the very first polygraph machine. This instrument was used to record pulse in continuous illustrated line. The technology required a “rubber diaphragm” to be connected to a vein located on the neck and the pulse of the wrist; this instrument was highly ineffective, due to being the first of its kind and lack of technological advances. This being said, James Mackenzie’s polygraph paved the path for many years of scientific and forensic work to come, which is why I will be adding this information to my timeline.

In 1921 the first modern and somewhat accurate polygraph machine was invented by John A. Larson, a psychologist at the Berkley Police department. This instrument was the first of its kind and was in substantial use in investigations of that time period. The 1921 polygraph machine was the first to have a constant measure of blood pressure and pulse to record change and variation in data, on a rotating drum of smoke paper.

I will strive to achieve this by following the principles of design thoroughly and using my newly gained Photoshop skills to achieve my goals. To create a visually appealing piece I would like to follow a color that stay consistent throughout the piece to show unity and that each part of my timeline belongs together. I will also use either the rule of thirds or radial balance to not only exemplify my knowledge of the elements of design ,but also have my piece look more visually balanced, calming, and
