In human-computer interaction and computer science, usability studies the elegance and clarity with which the interaction with a computer program or a web site (web usability) is designed. Usability considers user satisfaction and utility as quality components, and aims to improve user experience through iterative design. [4]
PDF/UA (PDF/Universal Accessibility), [1] formally ISO 14289, is an International Organization for Standardization (ISO) standard for accessible PDF technology.

Hallway testing, also known as guerrilla usability, is a quick and cheap method of usability testing in which people — such as those passing by in the hallway—are asked to try using the product or service.

It was developed by John Brooke [ 1 ] at Digital Equipment Corporation in the UK in 1986 as a tool to be used in usability engineering of electronic office systems.
Usability goals must address the three usability components, i.e. effectiveness, efficiency and satisfaction. [2] Their definition, for each of those components, must rest on the characteristics of the tasks that the tested system is supposed to support. [2] More practically, Mayhew [5] proposes that their definition should refer to:
