I came across this device the other day when browsing technology for potential use.

TAP

From what I’ve read, it’s a wearable keyboard and mouse that you wear while tapping your fingers or dragging your thumb across a surface to type or move a cursor.  For most of the applications they demonstrate it for, I think I’d rather use a real keyboard or use an on-screen keyboard.  I could see this being useful for people using an augmented reality display, though, which was the use case I was looking at.

However, they really need to make videos of people who are more proficient with it.  Typing looks painfully slow for normal use, and I think part of that is that the people in the videos don’t appear to be very proficient with it.
