Abstract
2D or 3D gesture commands are still not routinely adopted, despite the technological advances for tracking gestures. The fact that gesture commands are not self-revealing is a bottleneck for this adoption. Guiding novice users is therefore crucial in order to reveal what commands are available and how to trigger them. However guiding systems are mainly designed in an ad hoc manner. Even if isolated design characteristics exist, they concentrate on a limited number of guidance aspects. We hence present a design space that unifies and completes these studies by providing a coherent set of issues for designing the behavior of a guiding system. We distinguish Feedback and Feedforward and consider four questions: When, What, How and Where. In order to leverage efficient use of our design space, we provide an online tool and illustrate with scenarios how practitioners can use it.
