### Discussion  
The comparative analysis in Table 2 illustrates that the AGAPE platform distinguishes itself from other solutions by providing a comprehensive approach that includes health monitoring, activity tracking, social interaction, personalization, and user profiling. While many solutions focus on one or two aspects, AGAPE's integrated framework offers a holistic approach to addressing the needs of older adults.  
[PERSON] et al. [44] share similar advantages with the AGAPE platform. Their project also emphasizes personalized user profiles created through machine learning models analysing health-related quality-of-life data. Both platforms prioritize promoting social interactions and physical activity. However, the vINCI project by [PERSON] et al. employs advanced technologies such as RGB-depth cameras and blockchain for secure data management. These advanced features provide a more detailed activity tracking capability and

enhanced data security. On the other hand, AGAPE's use of more cost-effective and simpler technologies may offer advantages in terms of accessibility and ease of deployment.  
Despite its strengths, the AGAPE platform faces several challenges. One significant challenge is the variability in digital literacy among older adults. While the platform attempts to personalize interventions based on user profiles, the initial learning curve and technology adoption can be daunting for some users. Additionally, ensuring data privacy and security remains a critical concern, especially when integrating multiple IoT devices and platforms. Although the platform emphasizes usability and a user-centred design, continuous feedback and iterative improvements are necessary to cater to the diverse needs of the older population.  
The AGAPE framework comprises smart socks and IMU sensors positioned on the ankle. The OAs encountered challenges in wearing these sensors on a regular basis, particularly with the socks in warm and hot weather conditions. The OAs perceived the ankle-mounted IMU sensors to be unfashionable. We are investigating alternative solutions, such as placing an IMU sensor beneath a t-shirt to be more discreet. The step count algorithm requires adjustment to accommodate the sensor's changing position.  
In conclusion, while the AGAPE platform offers a robust and comprehensive solution for promoting active and healthy aging, it must address challenges related to digital literacy, data privacy, and continuous user engagement to maximize its effectiveness and user satisfaction. By learning from the strengths of other solutions such as [PERSON] et al.'s project, AGAPE can further enhance its platform to provide even more effective and secure care for older adults.
