Structure of the OCARIoT project

OCARIoT project is divided in 8 Work Packages.

A brief description of each Work Package is provided below:

WP1: Project Management, Quality Assurance & Reporting

It needs to be ensured that the project is managed efficiently, meets its objectives and the terms of the contract with the Commission and Brazil Government. Furthermore, it is necessary that the consortium agreement between partners is fulfilled, and that high-quality standards are guaranteed at all levels. This requires a strong project management and quality assurance work package. Within OCARIoT, a well-defined and rigid management structure will be established that allows the management team to operate efficiently. All management activities will be performed within this work package.package. Specific objectives of this WP include:

  • The overall general strategic and operational management and steering of the project, ensuring the accuracy, quality and timeliness of deliverables.
  • Ensure the seamless integration of the activities (i.e. manage the time and result dependencies) by reviewing and assessing the progress of OCARIoT activities towards the defined goals and objectives.
  • Measure the progress of OCARIoT in a quantitative way and give feedback to the partners to react accordingly.
  • Formulate and implement a quality plan and create related templates for using in the whole project.
  • Conduct the financial and administrative management of the project.
  • Establish and manage effective collaboration and communication systems.
  • Manage the public face of the project.
  • Manage liaison with the European Commission, and the production of periodic reports.
  • Co-ordinate and ensure the coherence of all technical developments between Work Packages.
  • Manage the Intellectual Property and its exploitation, including any legal agreements, such as the Consortium Agreement and other agreements required, access and exploitation of foreground and background knowledge.
WP2: Concept, Requirements and Specification

The focus of this WP is to share a common definition of the user requirements, needs and pilot scenarios in order to be able to identify all the specifications for the OCARioT solution. We will follow a Design thinking approach in order to put the OCARIoT users (children, families, educators) and involved stakeholders in the centre of OCARIoT design, implementation and evaluation process. This WP will also work on designing the architecture of the OCARIoT platform. Once the user and platform requirements have been identified, the system architecture will be defined along with a functional specification. This global architecture will be used to define OCARIoT features and their interaction within the system. Furthermore, the enabling technologies of OCARIoT platform will be  studied in detail within this WP. The main objectives of this work package are:

  • Provide the guidelines for the extraction of user requirements early in the project, based on the Design Thinking philosophy specially adapted to the OCARIoT application area and the requirements elicitation.
  • Define the technological baseline of the project.
  • Define the user requirements and functionalities needed by the users of OCARIoT.
  • Analyse the scenarios and requirements specifications
  • Specify the platform architecture.
WP3: IoT Data Integration for Childhood Obesity Modelling

In order to fulfil the high level objectives of the project, the OCARIoT platform must be able to acquire a great range of data; mainly data regarding the children's behaviour, in addition to the feedback freely provided by the parents, teachers and healthcare professionals involved in the child daily life. This data is necessary to be able to trace the behavioural pattern of the child, and with it being able to compute the obesity risk in which the child is actually under. As such, the specific objectives of this work package are i) mapping of child-generated inputs and autonomic acquisition of relevant data and ii) mapping of the disease. In fact, in order to achieve i), one must acquire data from several sources, especially data generated by the child. As such, physical sensors and wearables should be employed, and those devices must be carefully selected and benchmarked using a well-defined set of criteria. Moreover, the data will most likely be acquired from several devices, provided by different vendors. Thus, APIs and software components must be designed to take that into consideration. The same rationale applies in order to be able to consistently monitor the inputs being generated by several children at any given time. Since multiple data sources will be used to gather the inputs, the heterogeneous nature of the data being generated must be taken into consideration as well. This will influence the way in which the disease is perceived. Thus, a practical and consistent model must be built in order to map obesity and accomplish ii). In fact, statistics, metadata and medical insight must be used to build a robust and coherent model, in such manner that the gathered inputs convey into enough data to determine whether a single child is at risk of becoming obese or not (the pre-diagnose of the disease is implemented by WP4). Specific objectives of this WP include:

  • Definition and validation of sensors and wearables to be used in the framework;
  • Specification and development of a data acquisition component for sensors and wearables;
  • Data model specification for client devices sharing data across the framework;
  • Design and implementation of server-side components to handle the captured data;
  • Verification and validation of the captured data;
  • Integration of data capture components with the OCARIoT;
  • Translation of disease data (metadata, statistics and medical insight) into a model;
  • Identification of which data must be acquired to feed the disease model;
WP4: Personalized Obesity coaching plan and care guidance

This work package is devoted to the development of the a) methods and information processing algorithms for the offline and online management, fusion and analysis of advanced data from behavioural, eating, and physical activities of children, (b) apply these methods to manage and analyse new data that can also support the population of the obesity models developed in Task 3.3, and provide an intelligent DSS module to provide children with personalised obesity coaching plans and appropriate interventions. Thus, in this WP, online analysis will concentrate on the final OCARIOT IoT monitoring system aiming to cover specific situations during day time normal activity of the children both indoors and outdoors. The subsets data will gradually be merged to an integrated system. Moreover, advanced offline pattern analysis of such large amounts of data taking also into account the clinical and behavioural information available, will lead to integrative interpretation and better understanding of obesity and produce indicators related to eating and activity patterns of children, exploit the above indicators and determine the risk of developing obesity or eating disorders, and provide advanced decision making capabilities assisting the involved users. Specific objectives of this WP include:

  • Offline data management and analysis;
  • Development of an expert Decision Support System.
WP5: OCARIoT platform integration and interfaces

This WP is in charge of the integration of components developed in WP3 and WP4 into the OCARIoT platform. It also includes the UI and UX definition of the app and dashboard frontends. During this definition, outcomes from previously developed modules (such as the capture module), will be used in order to enhance the user experience. After this definition, both assets will be developed and integrated with other modules, such as the capture module, monitoring module and obesity data model. After the integration, verification and validation procedures will be executed based on international standards, and documented. This final procedure will be useful for future regulations. For the development process of the solution, take as the basis best practices recommended by the area of software engineering and interaction human computer watching concepts such as robustness, security, quality, accessibility and usability of the product produced. as methodology of development, use will be of the design process centred on the user cyclic advocated and adapted from Preece and Col. (2013), which makes the activities primordial the process of software, namely: A- survey of the requirements; B- specification / design (accurate description of the software which will be written by means of models); C- construction (code test), D- reviews continuous with the participation of users. In order to adopt a pattern in the production of the models generated in the process of development of the system, we used the language modelling unified (UML). Specific objectives of this WP include:


  • Integrate the components from WP3 and WP4 into the whole integrated OCARIoT platform.
  • Design and development of OCARIoT children app and dashboard.
  • Validation of the overall system functionalities.


WP6: User-centred Piloting and Validation

This WP is dedicated to the overall validation of the OCARIoT platform and the resulting impact on life quality of children. The detailed objectives are:

  • Implementation of the OCARIoT pilots to demonstrate the usability and user experience of the solution in Europe and Brazil pilot sites and also for different stakeholders (e.g. children as end users, and also families and healthcare professional staff);
  • Creation of a culture and a collective conscience in health that engages and empowers citizens, health professionals and clinical-care environment with regard to the promotion of healthy habits and behaviours;
  • Evaluation of children’ engagement and intent to further use the OCARIoT app;
  • Evaluation of families’, educators’ and healthcare professionals’ engagement and intent to further use the OCARIoT dashboard;
  • Conclusions and feedback to improve the overall ecosystem functionality and adaptability.

The envisaged assessment process will cover, as stated, the usability of the platform and dashboard developed according to the different user typologies and their needs; and the effectiveness on the OCARIoT app regarding both motivational/ engagement and obesity perspectives. The WP’s activities will be organised and scheduled to (1) take into account the iterative approach adopted by the project in developing the strategy, implementing the platform and performing prototypes; and (2) Be in synch with the relevant WPs (WP2-WP5).
