Abstract
Augmented reality (AR) allows a computer-generated 3D model to be superimposed onto a real-world environment in real time. The model can then be manipulated or probed interactively as if it is part of the real world. The application of AR in visualizing macromolecular structures is growing, primarily in showing preset collections of scenes for education purpose. Here, our emphasis is, however, on exploiting AR as a tool to facilitate scientific communication on the go. We have searched for freely available mobile software and custom-built tools which allow the display of user-specified protein structures. We provide step-by-step guides on a standalone app Ollomol (iOS and Android), as well as an in-browser web app, WebAR-PDB. Both of them allow users to specify entries from the Protein Data Bank (PDB) for an elementary AR experience. The application of AR enhances interactivity and imaginativity in macromolecular visualization.
