Calmingstone was originally designed in 2014 by Ramon Telfer, who – after suffering with anxiety himself – found that there wasn't a tangible product on the market to help him. When in the user's hand, the sensor picks up on their heart rate and mimics it through a softly glowing light and a slight pulsing sensation. As the user relaxes, the Calmingstone's pulse and glow become more subtle. Specially selected audio runs alongside the vibration and light, giving the user a comprehensive sensory experience. Each of the Calmingstone's functions can also be manually controlled. To alter the level of light, the device is flipped over; to alter volume, it is tipped up and down; and to turn the audio on, it is moved in a circle. "We want people to talk about their mind the same way we talk about our body," said co-founder Alex Johnson. "Sharing experiences and insights are so powerful in normalising the conversation."
