TruTru is a handheld tactile companion for non-clinical emotional wellbeing and mindful grounding. Through natural hand interaction, it senses physiological signals that may reflect stress-related changes in the user’s state. Its AI system then selects quiet, nonverbal responses, including soft light, subtle heartbeat-like pulses, creature-like sound cues and dynamic tactile feedback. Designed to be held, touched and stroked, TruTru provides a low-interruption sensory anchor for everyday moments of stress, distraction or emotional fluctuation.
