Information Transfer Rate Atlas is a website that collects and compares a measurement called information transfer rate, or ITR, across different ways people can send input to a computer: brain computer interfaces, eye tracking, speech, typing, and similar methods. The idea behind the project is that this number gets quoted a lot in research papers, but it is calculated in different, sometimes inconsistent ways, so the atlas tries to make the math behind each number visible rather than just repeating the headline figure. For every method in the atlas, several different scoring formulas, named after researchers such as Fitts, Wolpaw, Nuyujukian, and one based on Shannon's information theory, are treated as upper limits on the true transfer rate, and each entry is ranked using whichever of these formulas gives the strictest, most conservative bound. You can also switch the display to compare a single formula across every method. Each entry shows the full step by step calculation behind its number, traced back to the section or table in the original paper it came from, along with a note on whether the figure was reported directly by the paper's authors or had to be worked out separately because the paper did not give a comparable number. As of this writing, the atlas has 47 entries covering categories such as brain implants, eye and switch based spellers, silent speech methods like reading muscle signals or lip movement, pointing devices, and chord keyboards. The site itself is a static website built with the Astro framework, with the ITR formulas computed automatically at build time, and it is automatically published to GitHub Pages whenever changes are pushed. New entries or corrections can be proposed through a short form, a GitHub issue, or a pull request adding a file under a specific content folder, and every submission is reviewed by a maintainer before it is added. The project is released under the MIT license.
