Although technologies to disseminate information over the internet continues to evolve, the interfaces through which such information is communicated remain largely unchanged. In this article, Hogman et al. (the creators of the Parametric Press) highlight and examine interactive articles, which enable people to learn and engage with complex ideas more effectively – thereby making new technologies more accessible to broader audiences. They review over 60 interactive articles to examine how their authors use interactive content to improve the reading experience – by engaging readers with data (e.g. through animation and/or gamification), facilitating interaction with and understanding of complex systems (e.g. with simulations, in-browser sandboxes, and/or multiple representations), enabling personalized reading, reducing cognitive load (i.e. by providing additional details ‘“on-demand”) and inciting self-reflection (e.g. using self-explanation, quizzes). The authors also explore obstacles to developing interactive content, including due to lack of specialized skills, authoring tools, and suitable publications, and misaligned incentives.
