This tool provides an easy way to write and execute different types of interactive actions that are usually useful in experiments involving cognitive sciences. E.g., display an image/video, play sounds, show text, measure reactions to events (through key presses or clicks), measure action completion times, ask questions, etc. The existing tools for this purpose are either out-dated, closed-source, or written in a low-performance scripting language like javascript. This tool aims to be modern and performant, while at the same time maintaining ease-of-use.
To achieve native performance, this application is written in Rust using the egui graphical framework. To generate a task, a description file in the rust object notation (RON; see “Tooling” section of its README for syntax highlighting) format should be created by the experiment designer. The task file consists of three main fields: name, configuration, and blocks (self-contained pieces of the experiment that should be run in one sitting). Each block in itself consists of three main fields: name, configuration (overriding the task configuration), and actions. The actions are specified in the form of a tree (graph) with nodes of type Action.
For usage examples and installation instructions see the GitHub page.
DISCLAIMER: While this tool is functional and feature-rich, this project is highly experimental and its API is subject to frequent change. Use at your own risk.
