Many disciplines of multimedia and communication go towards ubiquitous computing and hands free- or no-touch interaction with computers. Application domains in this direction involve virtual reality, augmented reality, wearable computing, and smart spaces. Gesturing is one means of interaction and this paper presents some important issues in gesture communication, from a technological viewpoint as well as a user viewpoint such as the learning rate, ergonomics, and intuition. These issues must be taken into account when choosing the gesture vocabulary. A procedure is proposed which includes those issues in the selection of gestures, and to test the resulting set of gestures. The procedure is tested and demonstrated on an example application with a small test group. The procedure is concluded to be useful for finding a basis for the choice of gestures. The importance of using theory from ergonomics is also emphasized.
