Have you tried a Datahand? I love the idea of a glove-like fit for the hand with switches permanently located at the fingertips, but I wonder if the Datahand feels awkward to use because three of the five switches at each fingertip require the user to move the fingers either sideways or away from the body. I wonder if it's possible to develop control over those movements to such a degree that they feel precise and quick and easy.

The sideways motions in particular might always feel awkward because given the design of the Datahand, it appears that the entire finger, not only the fingertip, would need to move sideways. So even though the sideways motions are short in distance, they will always require a big mass of stuff (the entire finger) to move.

Usually when we want to move our fingertips sideways very rapidly and accurately, we assist the motion by flexing the palm laterally. We do this for example when we fret a guitar. But that doesn't appear to be possible with this device since the palms rest against a support.

I'm experimenting by holding one palm in a locked state with the opposite hand while trying to flick sideways or upwards with my pinky. It's slow and very awkward.
