“…Na maioria das vezes, a construc ¸ão de uma ferramenta de diagnóstico de sustentabilidade na agricultura envolve diversos interessados, gerando uma certa complexidade no processo de criac ¸ão da mesma [Whitehead et al 2020]. Envolver o usuário na construc ¸ão, torna o sistema mais compreensível, adaptável e com mais chances de ser melhorado, sendo necessário que a usabilidade do mesmo seja garantida [Goumopoulos e Mavrommati 2020]. Porém, a complexidade de utilizac ¸ão é um fatorchave quando se fala na adesão desta ferramenta [Goumopoulos e Mavrommati 2020].…”

A demanda por avaliações de sustentabilidade de sistemas agropecuários tem sido crescente nos últimos anos. A partir de uma metodologia específica para a produção leiteira, têm-se desenvolvido uma plataforma genérica denominada SQUADRO-i, visando o diagnóstico de sustentabilidade de diferentes tipos de sistemas. Este estudo apresenta o projeto-piloto da SQUADRO-i, um software que permite a construção de indicadores e de avaliações de sustentabilidade. No projeto-piloto já é possível construir indicadores quantitativos com seus respectivos parâmetros e realizar o cálculo de índice de sustentabilidade dos mesmos. O projeto ainda se encontra em andamento, porém já levantou-se a possibilidade da plataforma se adaptar a outras metodologias de avaliação.

“…A second app is an ambient app store with functionality similar to mobile app stores, enabling users to download new apps and manage the set of those currently active. A third app is an ambient space design studio, enabling users or providers to configure the connections to be realized in the environment comparable to the approach of Goumopoulos and Mavrommati [38]. They can do so manually or by choosing from suggestions given by our algorithm and even configuring the criteria and constraints for the that the suggestions are based on.…”

Self-Organizing and Self-Explaining Pervasive Environments by Connecting Smart Objects and Applications

In the past decade, pervasive environments have progressed from promising research concepts to available products present in our everyday lives. By connecting multiple smart objects, device ensembles can be formed to assist users in performing tasks. Furthermore, smart objects can be used to control applications, that, in turn, can be used to control other smart objects. As manual configuration is often time-consuming, an automatic connection of the components may present a useful tool, which should take various aspects into account. While dynamically connecting these components allows for solutions tailored to the needs and respective tasks of a user, it obfuscates the handling and ultimately may decrease usability. Self-descriptions have been proposed to overcome this issue for ensembles of smart objects. For a more extensive approach, descriptions of applications in pervasive environments need to be addressed as well. Based on previous research in the context of self-explainability of smart objects, we propose a description language as well as a framework to support self-explaining ambient applications (applications that are used within smart environments). The framework can be used to manually or automatically connect smart objects as well as ambient applications and to realize self-explainability for these interconnected device and application ensembles.

“…In effect, this means even people who are not familiar with high-level coding can use visual tools to develop functional applications, with nearly unlimited range of possibilities due to extreme flexibility of PWCT. The concept of pervasive or ubiquitous programing describes technological systems capable of 'presence' at many locations at the same moment (Goumopoulos and Mavrommati 2020;Gollagi et al 2020). For instance, a system could track the location of user's device, its status and activities, while using this data to make decisions about resource allocation or access permissions somewhere else (Fayed et al 2017).…”

Visual programming languages (VPLs) are inevitable tools to attract more people to the programming world. In this article, a novel VPL-programming without coding technology (PWCT)-is introduced. The main objective behind developing this tool was to create a general-purpose VPL that also possesses textual languages' capabilities. PWCT is a language that can be used to develop similar programs to the ones developed in C++ or Java for example. As the name indicates, PWCT requires no coding at all. A person only needs to know the basic programming concepts to be able to use the tool. PWCT has many attractive features and can be used to develop applications of different domain including pervasive computing. PWCT has been launched as a Sourceforge project, which currently has more than 240 K downloads for the tool and over 22 M downloads for the samples and tutorials. A staggering number of programs were developed in PWCT all over the world. This article focuses on the core aspect of the tool. In addition, a number of studies are carried out to evaluate the usability and productivity of the tool. Feedback from developers and results from the studies indicate that PWCT is a very appealing, competitive, and powerful language that can be used in developing pervasive and mobile computing applications.
