Elderly users can talk to the AI Companion instantly through voice. The AI Companion engages them in daily conversations, greeting them, checking on their health, showing care for their everyday life, and giving timely reminders (such as regular medical check-ups, monitoring blood pressure, or exercising more). The AI Companion uses a gentle and friendly voice, responding with empathy according to the elder’s emotions during each interaction. It encourages them to share more about their daily life, making every conversation feel as natural and comfortable as talking to a real person—effectively reducing feelings of loneliness. Reminiscence Training Mode: The AI Companion also helps with memory training by using photos and short videos uploaded by family members. This supports the elderly in recognizing family members’ faces and recalling past memories.
