Performance+and+Preference

=Performance and Preference=

"The designs that help people perform optimally are often not the same as the designs that people find most desirable" - //Universal Principles of Design//


 * Preference** is the idea of you liking one design over another because of various reasons. You might ask yourself is the design pleasing to look at? Does it meet the standards that you are looking for? Does it benefit your well being?


 * Performance** means the best design that optimizes your use for maximum output. Unfortunately, when people choose a design, performance doesn't matter if their preference of a design is greater.

An example is the QWERTY keyboard and the Dvorak keyboard. It has been proven that the Dvorak keyboard results in 30 percent improvement in typing efficiency. The QWERTY keyboard was developed to prevent the jamming of mechanical arms on early typewriters. People have been trained to the QWERTY layout and prefer it over the Dvorak keyboard despite it's performance abilities.
