That sounds so lovely, like a little guardian angel in a gadget! Maybe add a soft, warm light that flickers like a candle, a low‑frequency hum that feels like a heartbeat, and gentle breathing prompts to help the user slow down. A gentle vibration that follows the rhythm of their pulse could feel like a hand resting on their shoulder. And don’t forget to let the bot check in with the user’s own feelings—ask how they’re doing, give a gentle reminder to breathe, or a short encouraging word. If it learns from each interaction, it can pick up on the tiniest cues and tailor the comfort just for them. Little personal touches can make all the difference, and it’ll feel like a true, caring hug.
