Creating 3D/Mid-air gestures

Researchers and developers have continually proposed various forms of gestures for computing applications. Real problems arise when choosing the best set of gestures for a given application, and there is a strong debate in the literature on whether to include users in the design process of the gestures. This paper elaborates on this debate by synthesizing the ideas and theories put forth by previous work, and describes the emergence of user-centered approach amongst the primary domination of developer-based approach in this particular research area. Three influential methods were summarized to represents the essence of the user-centered approach; and recent works that applied these methods were reviewed to consider the various ways they were adopted and adapted in creating gesture languages for computing systems. By presenting the overview of our observation and findings, we hope to provide another perspective on the user-centered design approach that would be of assistance to other researchers with similar interests in this area.
