About Us

The FreeMoCap project began as a panicked attempt by Jon Matthis to maintain productivity after his human subjects research plans collapsed in the early days of the Covid 19 pandemic.

The original plan was to create a tool that would make it possible to study the neural control of human movement without access to the expensive, specialized motion capture equipment of his official research lab. However, in the process of developing early proof-of-concept versions of this system it became clear that there was a significant societal need for a high quality, minimum cost motion capture system. This (relatively small scale) public need derives from a larger inequity - namely, the ever-growing gap between the general population and the fruits of high science and technology.

From there, the focus of the project shifted from an effort to create a simple, in-lab research tool into the large-scale public facing project that it is today. To learn more about the history and background of the FreeMoCap project, please watch this presentation made to The Gathering for Open Science Hardware (GOSH).

The FreeMoCap project is now and shall remain a long-term effort and a work in progress. Stay tuned!

Legal Status

This project is developed, maintained, and managed by the FreeMoCap Foundation a registered non-profit corporation in the State of Massachusetts.

At time of writing (March 2022), FreeMoCap's Federal 501c3 tax exampt status is pending. Eligible donations made to the Foundation may be retro-actively considered tax-exempt provided that we gain 501c3 status within 27 months of the date of incorporation (i.e. March 2024).

To maintain financial transparency, the FreeMoCap Foundation will publish an annual report in the Summer/Fall of each year. In addition, per the legal obligations of a 501c3 tax exempt organization, the annual revenue to the FreeMoCap Foundation will be reported via an IRS 990 form.

(Fun fact - you can get the tax records of any American non-profit by searching "[Name of non-profit] IRS 990". You could, for example, use this information to determine how much of favorite university's operational budget derives from the tuition/debt of its student body. You know, if you're into that kind of thing.)
