Doppel's mood altering wearable is arriving this October

We meet the team behind the crowdfunded, psycho-physiological wristwear
First impressions: Doppel

I'm sitting in Doppel's noisy, top floor London HQ getting my first taste of empathic wearable tech. Wearing the smartwatch-shaped device, crowdfunded to the tune of £110,000 on Kickstarter last year, I was able to try out two different pulses/vibrations on the inside of my wrist. One to calm me down, one to energise me.

As co-founder and commercial director Jack Hooper explains while messing with my micro moods, the wearable is based on research into psycho-physiology, an area in which London has become a hub. (The four co-founders met on the Imperial and RCA joint Innovation Design Engineering course).

"We respond to the rhythm of music, other people's heartbeats and breathing and also our own. What we asked is – can we create an effect using rhythm that can change how you feel, that's unobtrusive and silent?"

A problem solving wearable

You could say it's been done before, a long time ago – with music

Doppel's tagline is "set your pace" and it's refreshing in a sea of health and wellbeing wearables which monitor your stats, spit out data and offer little by way of lifestyle suggestions. Doppel doesn't show you a graph of how stressed you are, it calms you down. Anyone who has switched to classical/jazz in the evening or created a pumped up running playlist knows the effect of rhythm on their energy, focus and mood. This is the same idea minus noise and minus distraction. So why now?

"A lot of the science we use is very current, it's very new," says Hooper. "Just recently a lot of work has been done in this area of psycho-physiology. People have only just started to understand how our bodies affect how we feel.

"Music has been studied in this way for over 100 years. We found papers dating back to before the last century, looking at why music affects the way we feel. You could say it has been done before, a long time ago – with music. We're just doing it in a new way."

Coming into focus

The device itself is worn with the main module on the inside of your wrist – it's light and comfortable to wear and the actual sensation of the vibration is noticeable but not annoying.

The slow, calming beat does, as Hooper describes it, feel like my own slow(er), calm(er) heart beat. The 120bpm rhythm, on the other hand, leaves me feeling part energised, part stressed out. I talk faster and louder after just 30 seconds or so in that setting.

This is, in fact, the default 'focus' rhythm that was used in a trial of Doppel at Royal Holloway University. In the test, participants who reported positive feelings towards the device, which they'd worn at this setting for one minute, experienced half as many lapses in concentration during a reaction time task as participants who didn't use the wearable. In lab terms, Hooper says that's doubling focus, which is a pretty compelling answer to the 'why use a wearable?' question.

The app we try out isn't the final software but shows how you're able to tweak presets of paired rhythms – one slow, one upbeat – before choosing which one to load onto the device. The touch controls are intuitive too – scroll around the surface to access the calm beat, double tap to start the up-tempo one. You can turn the device off when not needed and Hooper says most people will get "days of use, plural" in between charges.

Kickstarter backers, hold tight

Shipping the Doppel to the 820 original Kickstarter backers has been pushed back from the original target of April 2016. But the team is on track to deliver in October and posts regular progress updates from China, such as the switch to charging pins and a dock to make the device waterproof.

As well as Doppel's CEO Fotini Markopoulou raising investment in the US, the startup has also taken more than 1,000 pre-orders since the crowdfunding campaign.

"We'll deliver it and we'll make sure everyone is up and running," says Hooper. "We'll be trying to get as much feedback as we can from backers. Because we've designed the hardware to be as simple as possible, we're not throwing in things like activity tracking. It's simple but also quite flexible so we can provide updates just through software."

Other than getting the product out, the Doppel team is still interested in hearing how people are using the device. The potential of the system includes obvious, popular use cases such as increasing focus during the afternoon slump at work without caffeine, calming down during stressful situations, setting cadence when running and winding down in the evenings.

But the requests coming in are still unusual and surprising to the team: "People have asked about cadence for cycling, for rowing, staying focused during fencing or tennis matches, hospitals are interested in looking at ADHD and anxiety, people have asked about pets and this response to rhythm is mammalian, not just human."

And how do we know it's not just a gadget placebo? A further set of lab tests is planned to try measuring the wearable's ability to calm people down who are anxious or stressed. Though Hooper admits this might alter focus as they and the experimental psychologist Manos Tsakiris at Royal Holloway (who consulted on the product) haven't yet decided how to test this subjective feeling accurately.

"Placebo in the real world is very powerful but we have tests coming up to show it's more than that," he says. "Everyone will be different, we calibrate it based on a reading of your resting heart rate. But people's physiology changes day to day and over time so preference matters."

    I think this technology is incredibly promising. However, until they incorporate a heart rate sensor to deliver true biofeedback, the market for this will be quite small. If they slap on a reliable optical sensor, allow you to set profiles for your max level of excitement and calm, and then use subtlety changing tempos to guide you up and down depending on your moods and keep you in the zone at just the right level of intensity, they would be onto something game changing, especially for individuals with ADHD or anxiety disorders or anyone who wants a caffeine-like jolt of energy without going full manic. I'll definitely be keeping my eye on Doppel moving forward.
