Purpose

Baba is a novel AI "care copilot" designed to improve emotional well-being, cognitive stimulation, and social connection through emotionally present conversations, proactive engagement, and personalized communication. Unlike many existing solutions, Baba operates through SMS text and voice calls, requiring no apps, Wi-Fi, or new devices, making it particularly accessible to older adults.

Detailed Description

The purpose of this study is to evaluate the feasibility, usability, and preliminary impact of the Baba platform among older adults. This study will examine how older adults interact with Baba, how it integrates into the older adult's daily lives, and whether it contributes to improvements in well-being, cognitive engagement, and self-management. Findings will inform the feasibility of AI companions in supporting independent aging.
