Abstract
In the context of interspecies play involving humans, we find limitations when it comes to understanding most species. One reason for this may be the fact that we tend to anthropomorphize the other to be able to empathize with it. In light of this, how can we infer communication signs of other species so we are able to connect with the nonhuman world? We look for answers to this question by adopting a phenomenological approach that allows us to decentre from the anthropocentric perspective. We highlight animal studies, especially those that extend to them the notion of play, and the studies on interspecies playful interaction conducted in the context of animal- computer interaction. In addition, we propose considering empathy as an interspecies dialogical bridge with nonhumans. Finally, we argue about an expansion of the field of interaction design as an approach to the connection with the nonhuman world.

Abstract
The Wi-Fi networks are more and more omnipresent in our quotidian. It is a cheap technology that is available in many places, public or private (e.g.: schools, hospitals, public transports). The vulgarization of this technology is related to the impact that the concept of Internet of Things (IoT) has been having during the last years, revolutionizing the way to interact with “things”. The use of Unmanned Vehicles (UV) tends to increase, for ludic or professional ends. These vehicles allow to assist and minimize the human intervention in many situations, but one of the associated problems settles in their communication architecture that needs the use of an ad-hoc remote controller that restricts the control area. This work intends to explore the ESP8266 microcontroller to control a UV over a Wi-Fi connection. Three architectures that support the interaction with the vehicle are presented and specified. The real test scenario validated all the described architectures to control the vehicles. © Springer Nature Switzerland AG 2019.

Abstract
The arrival of Unmanned Aerial Vehicles (UAV) to the consumer market has been changing the way we interact with our surroundings. Fields like cinema and photography are improving with the possibility of reaching unsafe areas, as much as industry related companies that can now supervise their infrastructures safely. Besides many other professional areas, this fever also got into sports and UAV racing became a new way to compete. There are limited alternatives to control a UAV, each one with its pros and cons. The most reliable is the conventional handheld controller, a bulky equipment that requires practice and dexterity to be a good pilot. Consequently, technologically illiterate individuals, users with low dexterity or hand malformations and elders are departed from this game breaking technology, either for professional or recreational purposes. To expand the control of UAV to more member of our society, a different control equipment should be developed. In this paper we propose a solution based in two lightweight hand worn devices sensitive to motion changes. These changes are used to detect modifications in the orientation of the device, which are then transmitted through Bluetooth Low Energy (BLE) to a mobile app that is responsible for their interpretation as simple input or input patterns. The result of this interpretation should be used as flight commands to control a UAV. Through simple and intuitive hand movements, users can accurately pilot a quadcopter. This alternative presents a new and easier approach to control UAV that decreases the time that is required to learn how to use it, with the outcomes of an accentuated learning curve. The results obtained with the usability tests performed with users with different capacities of interaction, confirmed the viability of this solution, as much as its simplicity and intuition in the control. © Springer Nature Switzerland AG 2019.

Abstract
Recently, crowdsourcing platforms have been used to solve problems in the field of urban planning by involving crowds of citizens in performing tasks. However, the success of this approach is directly related to how work is managed. The goal of the present study is to make a broad characterization of work management in crowdsourcing approaches applied to urban planning through a systematic literature review. More specifically, we aim to investigate aspects related to the quality of work

Abstract
Recently, citizen involvement has been increasingly used in urban disaster prevention and management, taking advantage of new ubiquitous and collaborative technologies. This scenario has created a unique opportunity to leverage the work of crowds of volunteers. As a result, crowdsourcing approaches for disaster prevention and management have been proposed and evaluated. However, the articulation of citizens, tasks, and outcomes as a continuous flow of knowledge generation reveals a complex ecosystem that requires coordination efforts to manage interdependencies in crowd work. To tackle this challenging problem, this paper extends to the context of urban emergency management the results of a previous study that investigates how crowd work is managed in crowdsourcing platforms applied to urban planning. The goal is to understand how crowdsourcing techniques and quality control dimensions used in urban planning could be used to support urban emergency management, especially in the context of mining-related dam outages. Through a systematic literature review, our study makes a comparison between crowdsourcing tools designed for urban planning and urban emergency management and proposes a five-dimension typology of quality in crowdsourcing, which can be leveraged for optimizing urban planning and emergency management processes.

Abstract
In recent years, social curation technology has been successfully promoted as a means of addressing the problem of involving citizens with news content. Sites like Facebook, Reddit and Storify, just to name a few, allow their users to discuss, comment, share, identify and review news content from various sources. A key goal of this paper is to analyze the process of social validation in the context of Acropolis, a social computing platform that allows citizens to build and share their own narratives about complex or long-term news stories. The sense of social validation determines an increase in self-esteem, self-confidence, and instant happiness, when conveniently engendered in virtual environments.
