The makers of Doppel, London-based Team Turquoise, call it the next generation of wearable technology, one that can actually change the mood of the user.
A similar size and shape to a wristwatch, it provides tactile beats to the underside of the wrist for a mood-altering effect akin to listening various musical beats. By wearing the device on the inside of the wrist, this psychological mechanism places Doppel's pulse over the wearer's pulse, amplifying the effect. The speed of the pulse is controlled by the user's smartphone through an app that also measure's the user's resting heartbeat to provide two custom pulse options to stimulate or calm the user.
Jack Hooper, co-founder of Team Turquoise, explains that
upping the pulse tempo will get you alert, while slowing it down will make you relaxed. And you can use it in places where music may be distracting, or inappropriate, like in an important meeting or while presenting
The device may also be a useful exercising companion. Co-founder Nell Bennet notes
it feels like you're running on a machine even when you're outdoors, because you automatically keep to the rhythem and run at a constant rate which is really useful
