Hi, I'm Jack, one of the creators of doppel. Please ask us anything you'd like to know about it!
To give a bit of background, we are a team of Designers, Engineers and Scientists who research in to psychophysiology to create technology that can change how people feel, behave and perceive. doppel is our first product - a wearable that can actively change how the wearer feels to make them more alert or relaxed. It doesn't set out to monitor but instead it has a direct effect on the person wearing it.
It works using our innate response to rhythm. In the same way as upbeat or downbeat music, doppel can make you feel more alert or calmer. It is a completely natural and proven effect. Please ask if you want to know more!
