WP1 – Definition of User Requirements and Architecture

(1) User requirements analysis;

In order to determine the user requirements for the development of a system to assist people with fragility, a questionnaire was developed. The research results were published in a scientific article published at the ISI conference, CSCS2021, Romania, 2021. The objective of the questionnaire was to highlight the important requirements for potential users. The questionnaire was distributed to people working in / or assisted persons with fragility.

The research involved 58 participants (66.5% women and 34.5% men) between 30 and 80 years old. The age range is wide, because we wanted to extract information about the perception of potential users, as well as those who need assistance. 74.1% of respondents were in a position to have someone in care, and 25.9% were cared for by someone.

The questionnaire also included a series of questions about some indicators related to fragility, such as body weight, loss of balance, level of physical activity, feeling exhausted and the presence of dizziness.

There is a visible interest among respondents about some features that should be provided by the proposed system. These are listed below, taking into account the order of priority for the development of the system:

  1. Non-intrusive
  2. Confidentiality
  3. Ease of use
  4. Security
  5. Performance
  6. Reliability

(2) System architectural design specification.

The solution for assisted living proposed in this project, improves the living conditions of the elderly by intelligent automation of the environment (home) and monitoring their vital parameters. Assistance for autonomy at home thus ensures an independent living for the elderly and / or suffering from chronic or mental illness. The project will provide a monitoring, automation and event notification / alerting platform based on heterogeneous IoT devices, a data access services platform, offline analysis based on artificial intelligence and notifications, software utilities for system configuration / adaptation to the needs of the beneficiary , scaling services for designer and integrator.


WP2 – Initial cINnaMON prototype

(1) Initial smart bulb prototype specification report;

The research was based on an efficient positioning system for indoor lighting, based on electronic sensors. The system is ubiquitous and inexpensive and ensures constant monitoring at home. Lighting fixtures use current technologies and can be used to monitor the actions of monitored persons. The main functionality of the platform associated with lighting fixtures is to monitor people at home where they carry out their daily activities and to constantly find individuals and place them on the map of the house.

(2) Initial smart bracelet prototype specification report;

To detect the activities and energy consumed by the people who will wear the bracelets, we have integrated in the project architecture one of the Fitbit bracelets, so that we can process the data provided by the sensors in the bracelet. To measure the relevant indicators to determine the level of emotional fragility, the data taken from the bracelet sensors were: accelerometer, gyroscope, orientation sensor and heart rate sensor.

(3) Report on the intelligent location module in a building;

The transmission and reception of RSSI values ​​is done through the Arduino Mini Pro microcontroller that contains the Bluetooth module. For testing purposes, smart bulbs were considered to be placed in three different rooms to place the monitored person inside his or her home or building. The RSSI value provides information about the distance between the user’s smartphone and the smart light bulb.

Each MAC address of each smart light bulb is known, as well as the dimensions of the rooms in the house or building where the smart light bulbs are located. Smart bulb positions are indicated on the map using red circles. Their coordinates are known based on their position on the map.

The position of the monitored person’s mobile phone is characterized by the coordinates (x, y, z) which are taken over after the application of the trilateral algorithm. This is done in relation to the three nearby light bulbs belonging to the house or building of the monitored person.

(4) Report on the recognition of human activity;

In order to determine the level of physical activity of a person, the research activity focused on determining a mathematical formula, which with the help of data taken from the accelerometer sensor of the bracelet, to determine an approximate level. In this regard, an algorithm for recording the sampled data was implemented, which we later used to determine certain activities.

(5) Report on the user’s personal profile module;

Users of the cINnAMON system can create an account and log in to access the services offered by the digital platform. The administrator is responsible for granting access to users and must give a user credentials when requested. Setting up a project is a very important part of our system, as it allows the patient’s collected data to be available in the application for his doctor and the patient himself.

(6) Telemonitoring system report;

One project is the digital representation of a patient’s configuration. The designer must go to the patient’s location, install the sensors, the gateway and then insert them into the application. Each patient account will have an associated location.

(7) cINnAMON web application report;

Doctors can view the data collected for patients in tabular or chart form. In the Monitoring and Alert Scenarios module, patients can set thresholds for their monitored conditions. Notifications are sent to practitioners and the patient. The system sends an alert to a patient and their doctor when a value for a monitored condition is out of range.

(8) Data privacy report;

Establishing and preventing security requirements is extremely important for every system that processes confidential personal data. The system must ensure the confidentiality of data on patients, healthcare professionals, end-users and visitors. To ensure this, you must comply with European Union regulations on the protection of personal data: Law no. 190/2018 transposes into Romanian legislation the regulations of the General Regulation on Data Protection (GDPR). It introduces new provisions on liability, expressing consent to the processing of personal data, extensive regulations on data security breaches and the right to erasure. This law repeals the existing provisions at EU level by Directive 95/46/EC.

(9) Initial prototype test report.

The test system has been designed so that the functionalities can be tested independently of the others with which it communicates. The second level of testing is functional testing of the entire system. The functionalities are interconnected and complex scenarios that provide real use cases are verified. Although locating faults is difficult, system-wide functional tests can detect errors that are impossible to detect by unit functional testing, such as connection errors, communication errors, security breaches. The last component of the functional test is the testing of the client component. This ensures that the interaction between the user and the application takes place as specified.
