This is a fascinating potential wedge for an open-source initiative. Could you please elaborate as to what makes a device highly usable and of good quality, vs cheap and unpleasant to use?
I’ve long thought that open source would make a lot of sense for assistive devices, and that it has the potential to change incentives within the cartel of assistive device manufacturing.
There was a HackadayPrize 2023 competitor that worked on this [0]. He had to rethink the way those devices are built to bring the cost down.
That would be interesting to know if his solution could match the 4k$ in term of usability or if there is some issue like refreshing rate that make the piezo based system necessary for a good user experience.
