The NEX Project

In a rapidly ageing population new and efficient ways of providing health and social support to older adults are required that not only preserve independence but also maintain quality of life and safety. The overarching aim of the NEX project is to develop a technological solution that will enable older adults to remain living independently at home for as long as possible and facilitate caregivers to care for their family members or clients/patients in a non-intrusive manner.

NEX Project Overview
NEX Project Overview

 An overview of the NEX project 

The NEX project is a multidisciplinary research collaboration involving researchers in the Centre for e-Integrated Care, the School of Psychology, the School of Health and Human Performance and Insight Centre for Data Analytics in Dublin City University working with leading Irish technology companies Davra and Danalto. This project is funded by an Enterprise Ireland Disruptive Technologies Innovation Fund (DTIF). 

The NEX system is a combination of Internet of Things (IoT) technologies i.e. voice activated assistants, wearable devices, ambient sensors and smart plugs. These technologies collect data which can be used to identify patterns and changes in an individual's usual daily routine. Gradual changes in usual routine may be indicative of a person becoming unwell or that further support is required. The purpose of this project is to explore the development and usability of the NEX system. However, in a real life application, the NEX system data could be viewed in real time by older adults themselves, their family/caregivers or by a third party home care support service in order to support older adults to live independently.  

The project is structured in three phases to achieve the overall project aim. 

Phase 1 focused on identification of the user needs and requirements to inform the NEX system design. 

Phase 2 investigated the technical performance and participant engagement of the NEX system with older adults. 

Phase 3 of the project will commence in January 2022 and will incorporate the findings from phase 1 and 2 to inform the refined NEX system design. For this final phase of the project we are aiming to recruit 30 older adults aged 60 years and older being tested in the homes of participants for a 10-week period. Please get in touch with us via the contact us form or email to find out more about the trial and how you can get involved. You can read more about what is involved in this trial in the plain language statement document below.

We recently presented an overview of the NEX project at the Engaging  Ageing 2021 conference - The Future of Ageing and the Silver Economy. See our Research Manager, Dr Claire Timon, describe the project in the video below

Our industry partners


DAVRA and Danalto are two private organisations that specialise in IoT (Internet of Things). DAVRA is responsible for integrating the NEX system data collection processes using their IoT platform. Danalto’s role on the project focuses on developing technologies using their positioning intelligence expertise. To hear more about the work follow them on twitter  Davra  Danalto 


Phase 1 2020
Phase 1 2020

Phase 1 – User Needs & Requirements study

This co-design approach focused on partnering with end users to design the NEX system technology.

For this work we recruited older adults, family caregivers, healthcare professionals and home support workers to take part in the research.

Our original plan was to conduct face to face workshops with stakeholders to explore their needs and the possibilities that technology can bring to their lives. However as a result of Covid-19 we redesigned our research efforts to an online environment (online survey and Zoom workshops with stakeholders).

Overall, 426 stakeholders participated in face-to-face workshops, the online survey and the online workshops. Older adult stakeholders were the largest participant group (n=265, 62%) followed by family caregivers (n=83, 19%), health care professionals (n=51, 12%) and homecare support workers (n=27, 6%).

Key findings

-  We discovered that the majority of older adult respondents (86%, n=202) were willing to use technology to assist them to live independently in the future.

-  Technologies that were deemed most useful included those that could provide an emergency response, support home security and assist with communication.

-  From the older adult’s perspective, the key advantages to using technology included, increased independence and increased safety while key disadvantages included the financial investment required and concerns about data privacy.

-  For other stakeholders, the analysis highlighted that key areas where technology could assist older adults to live independently were: remote monitoring of family members (family caregivers), communication with clients (healthcare professionals) and falls support (home support workers). 

The DCU team from the Centre for eIntegrated Care and INSIGHT worked closely with the industry partners to map these user needs to appropriate technology solutions - The NEX system.


Phase 2 2021
Phase 2 2021

Phase 2 – the Friendly Trial

The prototype of the NEX system was developed in response from the user needs and requirements study (Phase 1).  The Friendly Trial focused on investigating the technical performance and participant engagement of the proposed “NEX system”.

To achieve this, we recruited 7 older adults (aged 60 years and older) to install the NEX system in their home for a duration of 10 weeks.

Covid-19 restrictions impacted our original study design which involved technicians and researchers visiting participants home for installation and training. To overcome the restrictions, the Friendly Trial was redesigned to involve self-installation of the NEX system by the participants themselves with remote support.

Key findings

-  The NEX system design has allowed for the collection of rich and extensive health and activity data from users’ home environments.

-  There are aspects of the current design that need to be improved upon to enhance adoption and usability i.e. the complexity of the self-install process, battery life of sensors and user acceptability of the wearable device used for the alert testing.

- We found that participants were open to adopting the NEX system if it means that it supports their ability to be able to live independently at home for longer, thereby postponing potential entry to residential care.

-  Participants review of their NEX system data highlighted that the user interface has clear potential to be a powerful mechanism of action which will impact on user acceptance and adoption of NEX.  So, from a design perspective, we need to carefully consider how we present the data to users going forward. 


Phase 3 2022
Phase 3 2022

Phase 3 -  Action Research Cycle (ARC)

For the final phase of the overall NEX project, we have taken on board the findings from the Friendly Trial to refine the NEX system and we now aim to trial this at a larger scale in the homes of older adults.

A key objective of this research study focuses on the use of the NEX system to collect data for the identification of Activities of Daily Living (ADLs) and the identification of longer term patterns of routine behaviour (periodicity) 

Activities of daily living (ADLs) are essential and routine tasks that most healthy individuals can perform without assistance. Therefore, the ability to detect whether older adults are routinely completing these activities is an important feature of the system.

For this trial we are aiming to recruit 30 older adults from Dublin and surrounding areas aged 60 years and older to test the NEX system in their home environment for a 10-week period.

The majority of study contacts will still take place over Zoom, however for this study the system will be installed and removed from participant’s homes by a NEX project technician.
