Table 5: Comparison of six-dimensional analysis results between group and individual contexts. For the sub-healthy group, the quantitative analysis revealed significant improvements in physical activity motivation (4.2/5.0), social participation (4.4/5.0), and a sense of achievement (4.0/5.0). The longitudinal observation data indicated sustained behavioral changes, characterized by increased voluntary participation and extended engagement durations in interactive sessions. This group's response pattern particularly validated the system's effectiveness in promoting active lifestyle changes through technological intervention. The healthy group demonstrated the highest overall technological engagement, with superior scores in terms of technology acceptance (4.3/5.0), learning motivation (4.2/5.0), and expectations (4.2/5.0). This group's performance was characterized by proactive technology learning behaviors and sustained interest in exploring expanded system applications. Their strong intergenerational interaction patterns suggest potential for broader implementation scenarios. A comparative analysis across these three groups reveals several significant insights. While each group exhibited distinct areas of strength, they all demonstrated substantial benefits from this system's implementation, particularly in the social interaction and engagement dimensions. The dementia group's unexpected proficiency, in terms of ease of use, validates the system's intuitive design. The sub-healthy group's improvements, in terms of physical activity engagement, suggest the system's potential as an effective behavioral intervention, while the healthy group's high technology acceptance indicates opportunities for extended applications and feature development. These findings collectively validate the system's adaptive capacity across different user profiles, while highlighting specific areas of effectiveness for each group. The consistently positive outcomes across all three groups, despite their varying cognitive and physical capabilities, provide strong evidence of the system's universal design principles and broad applicability in elderly care contexts.
