A prediction model used in human-computer interaction. It states that the time required to move to a target area rapidly increases as the distance to the target increases. The law was proposed by Paul Fitts, an American psychologist, in 1954 as a mathematical model of movement with limited cognitive capacity.
Fitts hypothesized that one would quickly select its first apparent target when reaching for an object before considering alternatives — a phenomenon called "target fixation." This tendency would increase progressively with increased distance between the subject and object until it eventually became exponential (i.e., too far away).

PPI stands for Point Per Inch. PPI is the number of dots per inch in a printer's resolution or the number of pixels per inch in a monitor's screen resolution. The more PPI, the higher your image quality will be as it becomes sharper and clearer. The lower your PPI, the lower your image quality will be, and the more likely you'll see individual pixels in an image.
