Human presence detection is a range of technologies and methods for detecting the presence of a human body in an area of interest (AOI), or verification that computer, smartphone (or other device controlled by software) is operated by human.
Software
Software is a set of computer programs and associated software documentation, documentation and data (computing), data. This is in contrast to Computer hardware, hardware, from which the system is built and which actually performs the work.

and hardware technologies are used for human presence detection. Unlike
human sensing, that is dealing with human body only, human presence detection technologies are used to verify for safety, security or other reasons that human person, but not any other object is identified. Methods can be used for internet security authentication. These include software technologies such

Examples
* reCAPTCHA is a CAPTCHA-like system designed to establish that a computer user is human (normally in order to protect websites from bots) and, at the same time, assist in the digitization of books.
* A sensor based on a piezoelectric film (EMFI sensor) is used to detect mechanical vibrations and the presence of a person seated on the rear bench of a vehicle. In order to distinguish between humans, heavy objects, and empty seats, signal processing techniques are used.
History
The first robot to successfully demonstrate a static motion detection capability was ROBART I, which was Everett's 1981 thesis project at the Naval Postgraduate School.
