What is moodtech? – Science behind Moodmetric

Moodmetric measures the electrodermal activity (EDA) of the skin, which is widely adopted in psychological research 1. EDA is generated by activity of the sweat glands.  Moodmetric measures the palmar skin on your finger. The palmar skin is the recommended EDA measurement location, since it has the highest sweat gland density2.

The unconscious actions of the human body are regulated by the autonomic nervous system. It consists of the sympathetic part and the parasympathetic part. The parasympathetic part controls the body’s rest-and-digest functions and the sympathetic part controls fight-or-flight reactions. When bodily functions are not of interest and the emotional side is, sympathetic nervous system is your choice.

The sweat glands are exclusively innervated by the sympathetic nervous system. This makes EDA an ideal measure for sympathetic activation.2 Electrodermal activity correlates to general emotional intensity, negative emotion, concern, and anxiety. 1, 3 These emotions cause almost similar electrodermal responses, which makes them very hard to differentiate. However, Moodmetric will tell you if certain parts of your day have brought up emotions or not. Inversely, Moodmetric tells you weather you are calm or not. This is particularly useful during your mindfulness, meditation and other calming exercises.

Mobile EDA devices have been used by scientists for some time2, 4, and now we bring this technology within everyone´s reach.

Signal accuracy

The signal accuracy has been proven in a study of 24 people by the Finnish Institute of Occupational Health by J. Torniainen et al.. The accuracy against a laboratory grade reference was found to be 83 %. They conclude:

“Clearly the ring sensor can be used to measure a valid EDA signal as indicated by the similarity of both event-related responses and the calculated features. The accuracy of the Moodmetric EDA Ring is adequate for psychological and physiological research when weighted against the advantage of conducting ecologically valid experiments outside laboratory conditions.”

The results have been accepted for publication in the 2015 conference of the IEEE Engineering in Medicine and Biology Society (EMBC 2015, August 25-29).

Our measurement has been proven to be accurate also by University of Tampere, Finland. The correlation with the reference equipment Nexus-10-MK II was good. Comparison details in charts below.

What a Slush!

What a terrific experience! Thank you Slush and all the people that visited our booth.

We got a lot on interesting feedback, lots of positive media attention, and many initial steps of cooperation were taken with companies in the health&well-being  market.

We had a constant queue for the demo and competition, which turned out to be even more exciting than we thought. The lowest emotional intensity score was reached by Hannu Hamari with an amazing result of 2/100. Congratulations!

The highest score was certainly reached by myself when entering on Black stage for the product launch. The stage was huge and what I could see from the spotlights was a large crowd of people interested in health and wellbeing. Thanks to our director Jonathan Clabburn for the great launch video, and Ella, Jaakko, Mikeal and Vesa who brought the film to life in front of the camera!

Road to Slush #4: Mood for Slush

 

Looking very bright indeed! It has been a huge amount of work done by the whole team to have everything ready for Slush, now after final checks the things seem to be in order. It all requires ups and downs of emotions as every bigger task in life, but finally the feeling is satisfaction over a great achievement.

See you all in Slush!  At our booth 2.09 on Wednesday you can try the Moodmetric Ring, measure your Mood Metrics and participate in a competition, please be welcome!

See here is my mood data from today, surprisingly calm up until now:

Road to Slush #3: Back stage pass

 

I posted today the following to Protomo Tampere facebook group:

PRODUCT LAUNCH: MOODMETRIC
Black Stage, Digital Health
Wednesday 19.11.
15:45 – 15:55

Toni from Headsted at first glance saw this would be happening at back stage. Which brought me thinking that I have actually never been at back stage of any kind. There might not be too many fans this time, but for sure a lot of excitement – maybe too much. Will there be a screen with digital numbers counting down seconds to go..

Not to get the stage fever yet I did some excel work and fine tuning of the competition we´ll have at our booth. Thanks to Aleksi the newsletter went out just right and only one bigger task now remains done. Which is cool, because only 3 days to go!!

Road to Slush #2: Big things and small details

 

My mailbox is filling up with Slush related material. Got to be careful not to pass anything important. Have to say, things have improved in past ten years in this – some while back all these emails would have been titled “Slush”. Title setting nowadays is extremely informative, saves a lot of trouble.

Setting up meetings with investors has been the one big and important thing and seems to be well in track now. The video´s final edit uploaded to system, just waiting for confirmation that the encoding really is the right one.

Other equally important things: the dress for entering the stage – check! (Thanks to Milla). Here a picture of another detail, that might be small but surprisingly useful:

Road to Slush #1 : Visible but rocky start

 

Its one week to the 2nd day of Slush, when we will have a stand for demoing and a presentation on the black stage. There is a lot of excitement in the air.

The great news is that we got superb press from Good News From Finland! and were featured as one of the health companies to look out for at Slush.

But always something… Last Thursday we noticed some problems at our website. Our front page started to show orange colors (instead of the Moodmetric green), font sizes started changing, and sometimes the server would give a 500-Internal Server Error. As these problems became more frequent, we decided we had to move web hosts to a company that would be more reliable and with faster website load times.

There has been a lot of work in preparing the needed materials. Most of it is now in order: flyers and business cards are on their way, the roll-up canvas is being printed and just found the right color t-shirts. Still things to tick off the list!

Mood and Myself

Am I entitled to good moods or doomed to endless worries and stress? Many times it feels I can´t enjoy my time too much, because people and the things around me are not in a optimal state. The car needs repair, the pile of work deliverables is too high, mother´s birthday party is yet to be organized – and the kids – their needs are acute, end-of-the-world type and expressed very loudly.

Where can the happy me be in the middle of this? How to switch to a good mood after someone spilled juice on clean laundry – or even stay in good mood while it happens. Impossible. And as to having a wider scope; there is so much suffering in the world, I do deserve to have my daily load of cry, being late, having trouble of all sorts and as a consequence – bad mood. The most I can do is to hope the next day will be brighter.

But what if those seemingly happier people are right when their advice is to find the things you enjoy, bring them into your life, take a moment to yourself and stand above the little nuisances that will evidently happen? Should I give it a try?

The sun just started shining (it really did), I take it as a sign and decide to apply some new approaches today: I will walk outside for at least 20 minutes, not hurrying. I will enjoy a good lunch – in peace, if possible. If things at work do not go well, I will regardless find two positive things that day. If the kids get a hysterical attack, I will sneak out to my chocolate stash and have a small piece. Then I hold them and sing them their favorite songs until they calm down.
