Darwin's book on expressions of emotion was one of the first publications to include photographs (Darwin, , 1872). The inclusion of expression photographs meant that readers could form their own opinions and could, like Darwin, survey others for their interpretations. As such, the images provided an evidence base and an 'open source'. Since Darwin, increases in the representativeness and realism of emotional expressions have come from the use of composite images, colour, multiple views and dynamic displays. Research on understanding emotional expressions has been aided by the use of computer graphics to interpolate parametrically between different expressions and to extrapolate exaggerations. This review tracks the developments in how emotions are illustrated and studied and considers where to go next.
达尔文关于情感表达的著作是首批包含照片的出版物之一（达尔文，1872年）。情感表达照片的纳入意味着读者可以形成自己的观点，并且能够像达尔文一样，通过观察他人来获取他们的解读。因此，这些图像提供了一个证据基础和一个“开源”。自达尔文时代以来，情感表达的代表性和逼真度的提高得益于合成图像、色彩、多视角和动态展示的运用。计算机图形技术被用于在不同表情之间进行参数插值以及进行夸张外推，这有助于对情感表达的理解研究。本综述追踪了情感如何被描绘和研究的发展历程，并思考了下一步的方向。
