A hybrid notation for communicating system gestures to stakeholders

In the field of human-computer interaction, the development of applications allowing users to interact with any part of the body requires heterogeneous development teams to cover all the areas of expertise necessary for the success of such applications. Therefore, a common language to define and document the interaction gestures is necessary so that all stakeholders with different backgrounds can understand each other. This is particularly the case between designers and engineers who use different tools and working methods to perform their tasks while their collaboration is of crucial importance for the success of the application. In this work, we propose a new method for representing spatial gestures to facilitate communication around them. To do so, we have reviewed the state of the art of existing taxonomies and practices for representing gestures. Based on this, our representation allows to present dynamic gestures with GIFs that show the gesture modeled with a humanoid avatar. Moreover, movement properties that cannot be included in the graphical representation can be specified in textual sections.
