MoodFlower is the emotional picture of your day. It shows your emotional intensity on a clock face, starting from 6am till 6pm, and the same for the evening and night. Continue reading “Moodmetric features: MoodFlower”
Scope tells about the instantaneous reactions of the wearer. When you feel something, your autonomous nervous system reacts and small changes can be measured from your skin.
The Moodmetric Ring detects the changes that can be followed online with the smartphone app. All the reactions cause an upward jump on the Scope, the bigger the emotion, the higher the curve goes. The physical response delay is 1.5 seconds, so the jump is visible 1.5 s after seeing a ghost… Continue reading “Moodmetric features: Scope and Wearing the ring”
Moodmetric captures the intensity of your emotions when you wear the ring. This is the basis for understanding the effects emotions have on us. Continue reading “Emotional Intensity”
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.
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 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!
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:
I posted today the following to Protomo Tampere facebook group:
PRODUCT LAUNCH: MOODMETRIC
Black Stage, Digital Health
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!!
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:
