Field Trial

12 Months

70 Test Homes

4 Countries


One of the most essential parts of the A4A project is the involvement of end-users during all project stages.

The main end-user target groups are dyads of active older adults living independently in their smart home or in an assisted living environment on the one hand (primary target group), and their formal or informal caregivers (e.g. next-of-kin) who take care of them on the other hand (secondary target group).

Furthermore, tertiary end-users are involved in the project, such as municipalities, B2B2C business partners or third party service providers.

In so-called ‘Advisory Boards’, end-users have been involved in co-creating the A4A solution. In early 2022, inputs and requirements have been collected on the product, some of which are: 

  • Ease of use (plug-and-play);
  • Possibility to actively switch the devices on and off (e.g. when there are guests)
  • Possibility of sending care alerts to next-of-kins if e.g. the older adult did get up in the morning;
  • the possibility for the older adult to cancel an emergency notification to the next-of-kin


The field trial aims to test and train the algorithms through the collected sensor data, recognizing activities of daily living for the detection of anomalies. If anomalies are detected, notifications will be sent to the informal or formal caregiver. 

The consortium gathers feedback throughout the project from the 70 Test Homes in Romania, Portugal, Denmark and Switzerland.

According to the end-user organisation in each country, the product scope for the trial phase is adapted:

  • In Switzerland, the business scope solution is installed in order to gain inputs from end-user dyads on the planned commercialised product.

  • In Portugal and Denmark, the learning scope solution will be tested. Additional sensors will be installed to train the algorithms through the collected data for the detection of anomalies.

  • In Romania, the full scope solution will be tested which includes a voice agent device to allow voice-based interaction between residents and the platform.

Inputs to the project can be given through the responsible organisation in the country in question, or through the contact form on this website.
