Abstract. Gesture recognition is an emerging cross-discipline research field, which aims at interpreting human gestures and associating them to a well-defined meaning. It has been used as a mean for supporting human to machine interaction in several applications of robotics, artificial intelligence, and machine learning. In this paper, we propose a system able to recognize human body gestures which implements a constrained training set reduction technique. This allows the system for a real-time execution. The system has been tested on a publicly available dataset of 7,000 gestures, and experimental results have highlighted that at the cost of a little decrease in the maximum achievable recognition accuracy, the required time for recognition can be dramatically reduced.

“…Allowing information visualization with no constraints related to touch reachability, still keeping systems interactive Limiting vandalism in public deployment, as a direct consequence of the previous one. Simplifying and encouraging multiple parallel interactions, mainly due to the higher allowed interaction distance . In fact, the interaction distance impacts the available space in front of the interactive system: the higher the interaction distance, the more room for multiple users. …”

SummaryIn the last decades, we have witnessed a growing interest toward touchless gestural user interfaces. Among other reasons, this is due to the large availability of different low-cost gesture acquisition hardware (the so-called "Kinect-like devices"). As a consequence, there is a growing need for solutions that allow to easily integrate such devices within actual systems. In this paper, we present KIND-DAMA, an open and modular middleware that helps in the development of interactive applications based on gestural input. We first review the existing middlewares for gestural data management. Then, we describe the proposed architecture and compare its features against the existing similar solutions we found in the literature. Finally, we present a set of studies and use cases that show the effectiveness of our proposal in some possible real-world scenarios.

“…First of all, experimenters must take into account all the influencing factors of a public place. The best results may be achieved conducting the study in-the-wild [10], although this increase costs and efforts in terms of time and set up challenges. Furthermore, researchers must take into account issues like the need of overcoming the display blindness [4] andprobably more complicated -the interaction blindness [3].…”

Public displays have lately become ubiquitous thanks to the decreasing cost of such technology and public policies supporting the future development of smart cities. Depending on form factor, those displays might use touchless gestural interfaces that therefore are becoming more often the object of public and private research. In this paper, we focus on touchless interactions with situated public displays, and introduce a pilot study on comparing two interfaces: an interface based on the Microsoft Human Interface Guidelines (HIG), a de facto standard in the field, and a novel interface, designed by us. Differently from the HIG, our interface displays an avatar, which does not require an activation gesture to trigger actions. Our aim is to study how the two interfaces address the so-called interaction blindness -the inability of the users to recognize the interactive capabilities of those displays. According to our pilot study, although providing a different approach, both interfaces proven effective in the proposed scenario: a public display in a campus building's hall.
