With the European population rapidly aging, addressing the vulnerabilities associated with physical and cognitive decline is essential. Promoting an active lifestyle among older individuals has proven effective in preserving health and independence. Growing evidence suggests that combining cognitive and physical exercises can significantly enhance both cognitive function and physical health, especially among sedentary elderly populations who are at increased risk due to physical inactivity.

This thesis, conducted in collaboration with the Portuguese company Neuroinova, presents the development and evaluation of a digital intervention aimed at integrating physical exercises into their platform for cognitive training COGWEB in individuals experiencing cognitive decline or impairments. The integration process started with ACTIVAS, a program developed in collaboration with researchers from the University of Aveiro, who provided guidelines for an effective physical exercise regimen based on personalization and progression. However, motivating users to adhere to the program, particularly in a remote setting, remained a challenge.

Understanding the needs and barriers of both patients and professionals was crucial to shaping a program that positively impacts user motivation.
Utilizing a user-centered design approach, including generative sessions, interviews with healthcare professionals, and literature reviews, two primary user groups were identified: sedentary individuals with minimal physical activity and busy active individuals with irregular physical exercise patterns. Despite individual differences, the insights revealed that successful integration of physical exercises into COGWEB requires clear, structured guidance from a trusted professional, such as a physiotherapist, alongside engaging and enjoyable exercise activities. Personalization of the program emerged as a key factor in addressing these needs.

The design process focused on ensuring effective guidance and engagement by iteratively testing various prototypes of exercise sessions, with special attention to interaction qualities such as being engaged, guided, proud, trusting, and in control.
The final concept involved a session where cognitive tasks in the form of games—similar to the original COGWEB format—were paired with physical movements and exercises, allowing users to train both cognitive functions and their body simultaneously. Emphasis was placed on providing clear instructions and professional guidance through the presence of a physiotherapist.

Final test results showed promise in motivating sedentary individuals to participate in these sessions, achieving the design goal of ensuring guidance and engagement. While the design objective of this thesis was met within the study's scope, further work is necessary to implement and evaluate the program's long-term effectiveness in real-world settings. The findings suggest that this approach has the potential to significantly increase physical activity levels and improve adherence among elderly COGWEB users, contributing to their overall well-being.
