Best Buy is placing a heavy bet on the growing need for home-health tech services as it aims to reach 5 million seniors (up from 1 million today) in the next few years. The push into home monitoring will include technologies based on remote response and predictive health systems. Products might "include algorithm-driven pendants that track how a senior is walking and predict the risk of falling, refrigerators with sensors that measure whether an individual has been eating, and wireless scales that monitor patients with congestive heart failure." The retailer would also partner with insurance companies who want to preventively "monitor patients at home to avoid hospital stays." Atolla is an MIT-based start-up that is using artificial intelligence (AI) and machine-learning to create custom face skin-care creams for its customers.
