The vOICe vision BCI app for Android crossed the 600,000 cumulative installs mark from Google Play https://play.google.com/store/apps/details?id=vOICe.vOICe Compare this to the number of Neuralink Blindsight brain implants in humans to date (spoiler: zero). #noninvasive #BCI #blindness
Some blind people (late-blind as well as congenitally blind) have been using The vOICe vision BCI for over 20 years now, hence already starting before Android came along back in 2008 https://www.youtube.com/watch?v=Bu1-1pW0NNw
