This paper is about using gestures for humans to interact with machines. They go over a lot of issues such as culture, the different types of gestures, creating a universal vocabulary, ergonomics & bio-mechanics, approaches to finding gestures, and, finally, they present an experiment.
A big hurdle in building gesture based systems is that the gestures are generally culture dependent. With a keyboard, which is dependent on a language, it can more easily be translated to be used by another culture. It is not so easy with gestures. A universal gesture language could be created, but there will be a huge learning curve for most, if not all, cultures. One example stated is that a ring made with thumb to index finger means OK in America and it means Money in Japan.
