Selection mechanism gestures are used in Natural User Interfaces (NUI) to designate elements in a User Interface. They usually involve simple gestures with limited interactions. Being able to use more than one gesture simultaneously increases the vocabulary of the interactions. In this paper, we present MultiX Click, a new algorithm to detect midair multi-click gestures. Our approach allows the detection of multiple midair finger clicks using a depth sensor. To show the potential of our algorithm, we implemented a midair multi-click keyboard and a midair piano that use simultaneous multi-clicks. In the midair multi-click keyboard, we mixed single and multiple clicks with the ability to retrieve the location of a click, and as a result we were able to increase the gesture vocabulary. This paper explains in detail the algorithm we used to detect multi-clicks. We also explain about some preliminary experiments for evaluating it.
