...However, designing effective interfaces with mid-air gestures, is not an easy task because it is application dependent and must fulfill many requirements at the same time.
Despite the availability of general design guidelines in the literature, clear and well-established procedures for the optimal design of mid-air gesture-based interfaces are, to date, not available and still remain an open issue.
