I have to quibble with two of the quotes in this article on the new gesture interface from FingerWorks. First, their CEO says “Unlike having to remember a sequence of keys, the gestures become part of your motor movements, so they are a part of your motor memory in your brain.” While I believe that gestures will be a nice, natural way of communicating commands to a computer, it is untrue that key sequences do not become motor memory. Typing is a very rapid means of communication, and much of it is motor movement memory. A better memory example would have been the gesture device’s improvement over the mouse. Mouse movement, because you can not guarantee where the pointer will be, is not as reliant on motor memory (though the best-designed mouse interactions with user interfaces like pie menus become motor memory gestures). The second quote is from interaction guru Don Norman who says “Having to move your hand back and forth from the keyboard to the mouse really is an unnecessary activity.” True indeed. But you can solve that easily with many alternate pointing devices that fit into your keyboard. Quotes taken out of context can be deceiving, I know, but let’s pull out quality reasons for why gestural interfaces will be so useful. How about: typing and mousing is unnatural, but humans gesture all the time!
