Not sure what a Dangler Doodad is but the SYNAPSE (Worlds Smallest BCI Device) as been researched/studied and represented is very comparable to the skull cap BCI's. The device would work in conjunction with a cellular device or even iPad/Tablet and loved ones can see requests.
I don't find it funny making fun of people whom can't communicate for themselves in bathroom matters. I personally know individuals whom this device will benefit greatly.
