Joseph Angelo Todaro introduces a website by John Yablonsky that outlines principles for user interface design.

Aesthetic Usability Effect01:00

This principle states that aesthetically pleasing designs are perceived as more usable, supported by a 1995 study on ATM UI by Misaki Kurosu and Kaori Kashimura.

Doherty Threshold02:00

Walter Doherty and Arvind Doni's 1982 research shows productivity increases when computer responses are under 400 milliseconds.

Fitts' Law03:00

Proposed by Paul Fitts in 1954, it relates the time to acquire a target to its distance and size, influencing design for quick access.

Hick's Law04:00
