The preferred solution actually moves my arm around a bit so that it works in a physical office. For remote work, there are so called "mouse jigglers" [1], but those do not require sunglasses to work.

Yeah but mouse jigglers 1/ have to be plugged in / occupy a USB port, 2/ usually don't turn off when LOGOFF, resulting in battery depletion and 3/ don't work on remote servers where you would want an RDP session to stay open but there are group policies that prevent it.

I wrote a small C utility that avoids all 3 problems and now I couldn't live without it!
