Talking to a stroke survivor changed how I see BCI latency
Met this older guy at a rehab center last Tuesday while visiting a friend. He had a stroke 10 years back and lost most of his right side movement. They let him try a research BCI for a trial, just moving a cursor on screen. He told me the 200ms delay felt like an eternity, like his hand was being dragged through mud. I always thought sub-second response was basically instant, but watching him struggle with that wait made me rethink what actually matters. For someone with limited motor options, even half a second of lag can mess with their sense of control. Got me wondering what latency threshold feels natural to people here, is 100ms still noticeable to any of you?

And that lag probably messes with their brain's timing too, making the whole thing feel wrong.
