A Smart Watch Controlled by Twists, Tilts, and Clicks

A movable smart-watch screen makes it easier to read a map or play a game.

The first time I tried out a smart watch with a touch screen, I quickly went from feeling excited to feeling clumsy. Tapping or swiping the small display on my wrist often failed to yield the response I expected. It might have been the quality of the screen, but it may have also been simply that the screen was too small and my fingers too big.
