{{emotion}}

Interest is a feeling or emotion that causes attention to focus on an object, event, or process. In contemporary psychology of interest,Silvia, Paul (2006) [https://books.google.com/books?id=J2YQAAAACAAJ Exploring the Psychology of Interest]. University of Oxford the term is used as a general concept that may encompass other more specific psychological terms, such as curiosity and to a much lesser degree surprise.{{Citation needed|date=February 2009}}

The emotion of interest does have its own facial expression, of which the most prominent component is having dilated pupils."We cannot help but reveal our interest in (and attraction to) others through the size of our pupils."--Satoshi Kanazawa, PhD, an evolutionary psychologist, Reader in Management at the London School of Economics and Political Science, and Honorary Research Fellow in the Department of Psychology at University College London, and in the Department of Psychology at Birkbeck College, University of London, in his blog [http://www.psychologytoday.com/blog/the-scientific-fundamentalist/200810/barbie-manufactured-mattel-designed-evolution-vii#== Scientific Fundamentalist][http://www.bbc.com/future/story/20190108-why-meeting-anothers-gaze-is-so-powerful Why Meeting Anothers Gaze Is So Powerful], BBC, Christian Jarrett, 8 January 2019

Applications in computer assisted communication and B-C interface

In 2016, an entirely new communication device and brain-computer interface was revealed, which required no visual fixation or eye movement at all, as with previous such devices. Instead, the device assesses more covert interest, that is by assessing other indicators than eye fixation, on a chosen letter on a virtual keyboard. Each letter has its own (background) circle that is micro-oscillating in brightness in different time transitions{{clarify|date=June 2017}}, where the determination of letter selection is based on the best fit between first, unintentional pupil-size oscillation pattern and second, the circle-in-background's brightness oscillation pattern{{clarify|date=June 2017|reason=What is this/how is this derived physiologically from the person?}}. Accuracy is additionally improved by the user's mental rehearsing of the words 'bright' and 'dark' in synchrony with the brightness transitions of the circle/letter.Mathôt S, Melmi J-B, van der Linden L, Van der Stigchel S (2016) [http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0148805 The Mind-Writing Pupil: A Human-Computer Interface Based on Decoding of Covert Attention through Pupillometry].

Measurement of sexual interest

In social science measurement methodology, when the intensity of (sexual) interest needs to be measured, the changes in pupil size – despite its weaker, but still consistent, correlations with other measures such as self-reported measures of sexual interest's orientation – have been proposed as its appropriate measure.Rieger, Gerulf; Savin-Williams RC (2012) [http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0040256 The Eyes Have It: Sex and Sexual Orientation Differences in Pupil Dilation Patterns].
