Nous avons le plaisir de présenter le 3ème numéro de la revue “Internet des objets”. Il est composé
de six articles qui traitent plusieurs facettes de l’Internet des objets à la fois les techniques et les
usages. Ci-dessous, nous présentons les résumés des articles.
This article is a deepening of our article that was published in 2017 in the journal. We took some elements but we also developed other concepts to make a consequent synthesis on the IoT. We present, 1) Connected Object (OC), 2) Internet of Things: Definition, 3) Steps and Technologies in the IoT Ecosystem, 4) IoT to the Internet of Everything (IoE), 5) IoT and Big Data, 6) Cloud computing applied to Big Data and IoT, 8) Data Science and IoT, 9) Issues and challenges of IoT, 10) Opportunities and threats of the IoT ecosystem, 11) Security of the IoT, 12) Blockchain and IoT, and 13) in conclusion, we summarize the perspectives of Ido.
The article presents a way to represent privacy in the context of the Internet of Things via
diagrams. Using pretopology, we study how to create a graphical and conceptual organization of privacy that can allow its parameterization by manipulation of the graphical elements of the diagram. In the first part of this article, we define what privacy is and we present important work that deals with this topic. Then, we present some concepts of pretopology and we detail the interest in using it for our modelling. In the second part, we study the modelling of privacy in the Internet of Things by using the example of a smart watch. Finally, we conclude by discussing future work from this article.
We propose in this article to analyse children’s activity during the use of a digital and tangible artifact destined to create and listen stories (Lunii - La fabrique à histoires). Our study, based on ten childrens, builds on ergonomics process study an artefact in use. Collected data are analysed through Rabardel’s instrumental theory to set up schemes and genesis present during Lunii’s use. We mobilize complementarily Vygotski’s theory of creative imagination to answer to this question: what is the influence of this narrative and connected artefact on the development of the creativity?
This article deals with the uses of connected objects in the field of service design and mHealth. It is based
on a design-driven research, a work-in-progress in collaboration with the University Hospital in Nîmes. The objective is to
show, by experimenting and prototyping, that a digital service, incorporated in a care network can be useful to detect, take
care of and follow insomniac patients. The article aims at answer to the following questions: how can the design of
mHealth technologies drives to rethink at the same time the cooperation between health professionals, the patient’s
journey map, and the role of the different stakeholders? How can we imagine a use of health datas and their visualisation
framed in a human-centered vision of technologies and social innovation in order to improve therapeutic education? How
digital interface, connected objects and datavisualisation can transform the communication between the patients, and
health professionals and the administrations? From the observation of the current uses on the field to the co-design with
the stakeholders of a service prototype, we try to explore the necessary conditions to favour the communication between
health professionals and patients based on a device designed for these users. The objective of this article is also to
explain the contribution of connected objects to Healthcare, as long as they are integrated in care’s professionals
network.
The Internet of Things encompasses a multitude of connected devices with advanced functions for the
automation of tasks and assistance to individuals, raising technical, political, social and economic challenges. Learning is
linked to these challenges in several ways: the machine learning development contributes to the functioning of connected
devices, which in turn stimulate human learning by diversifying practices and tools. Learning methods can lean on recent
works in neuroscience that identify cognitive resources for learning, such as attention, engagement, feedback and
consolidation. In addition, learning has been modified by technological change: after printing, computing and
telecommunications, the Internet of Things is a new information medium for knowledge transmission. Based on three
dimensions (data, interfaces and pervasiveness), we propose a classification of possible articulations of the Internet of
Things to support learning. The study of this relationship shows that the Internet of Things promotes exploration and
experimentation, the setting up of authentic situations and the contextualization of learning.
Internet of Things (IoT) is the way to interconnect smart objects that are capable of collecting data via sensors and making appropriate decisions. Data collection and data processing can be either done locally at the level of these objects or outsourced on the Cloud, exploiting unlimited Cloud resources. In this context, one of the major issues is the scheduling of the data transfer
between objects and/or the Cloud. This challenge is comparable to that of business process management (BPM) in companies, where data management is often carried out by Workflow processes because of their efficiency in terms of automation, optimization and scheduling. These processes are modeled using methods such as Business Process Modeling Notation (BPMN), which is based on tasks, events and gateways. The gateway is represented thanks to flow control operators such as AND, OR and XOR which are limited to the processing of several instances of data flow processes. We propose, in this paper, to adapt the BPM to the IoT process management, to improve the automation, scheduling and optimization of the data flowing between objects and/or the Cloud by providing a semantic operator called “GIOT” (Gateway for Internet Of Things) to allow intelligent data transfer in smart homes.
