Welfare technology is becoming essential for promoting older adults’ well-being, reducing health risks, and enhancing social engagement. While many welfare technology living lab studies focus on single devices, integrating multiple digital tools may offer greater emotional and cognitive benefits. This study investigates the effects of a living lab-based intervention using two digital devices: one targeting cognitive function (D1) and the other targeting physical function (D2). A community-based pretest–posttest design was conducted in South Korea with 65 participants, divided into three groups using D1, D2, or both. Over 10 weeks, participants attended weekly 60-minute sessions. Results showed the combined use of D1 and D2 led to greater reductions in anxiety, depression, and memory loss than single-device interventions. These findings highlight the importance of integrating cognitive and physical activities through interactive technology. This study contributes to social gerontology by demonstrating the value of multi-modal digital interventions in supporting older adults’ care.
