Thermal imaging-based physiological and affective computing is an emerging research area enabling technologies to monitor our bodily functions and understand psychological and affective needs in a contactless manner. However, up to recently, research has been mainly carried out in very controlled lab settings. As small size and even low-cost versions of thermal video cameras have started to appear on the market, mobile thermal imaging is opening its door to ubiquitous and real-world applications. Here we review the literature on the use of thermal imaging to track changes in physiological cues relevant to affective computing and the technological requirements set so far. In doing so, we aim to establish computational and methodological pipelines from thermal images of the human skin to affective states and outline the research opportunities and challenges to be tackled to make ubiquitous real-life thermal imaging-based affect monitoring a possibility.

Infrared imaging can only produce reliable and valid results if the technique follows established standards. In medical applications these standards are based on the physics of heat radiation and the physiology of thermoregulation of the human body. This paper describes the requirements for the location, setting up the equipment and the preparation of the human subject to be investigated. A list of references is given to support each part of the recommended procedure. Despite the fact that thermal imaging has been available for many years, there are still some applications of this technique which require more research.
