Less Is More: Design Considerations for Interactive Pharmacometrics Tools—A Case Study Using the Model Visualization Platform (<scp>MVP</scp>) App

The shiny R package has enabled pharmacometrics (PMX) scientists to create and share interactive R-based tools, or "shiny apps". Initially, shiny apps are developed ad hoc (i.e. project specific) to provide simulations, and their complexity have evolved to be more general-purpose and "platform-like" in recent years. Despite their complexity and increased amount of features, an unexplored aspect is the design considerations for user interface and user experience (UI/UX) to optimize end-user interactivity and enjoyment.
