Moodmetric Software Development Kit now available

Moodmetric now offers you the opportunity to include ring support in your own app. Emotional intensity tracking provides unique data to be used in applications only limited by imagination:

  • digital health

  • product marketing, product testing

  • music

  • entertainment

  • gaming

  • dating…

The data available for developers is based on the Moodmetric number, ranging from 0 to 100 and describing how strongly the wearer of the ring is feeling.

Moodmetric offers a beta license of our software development kit free of charge until release of the final licence. An interface is documented directly to the ring to make sure that you can run your application on any platform, as long as it supports Bluetooth 4.0. We provide full documentation for the interface and also example applications for iOS and Android. We also provide technical support to help you get going.

Some features in more detail (you will have the full description in the SDK package)

– The MM number notification tells if the person is very stressed or emotionally loaded. High MM notification is issued when MM number is elevated for over 5 minutes.
– The Relax notification tells if the person has successfully managed to relax for example in a meditation exercise. Relax notification is issued when MM number is low for over 5 minutes. This feature requires a ring with application version of 1.0.1 or above.
– The strong reaction notification tells if a strong emotional reaction has been detected at a certain moment. You can test responses e.g. to images and sounds.

The Smart Jewerly Designer

Vesa NilssonSilversmith and designer Vesa Nilsson shares his views about Moodmetric and the future of jewels.

www.ozjewel.com

What were your first thoughts when you heard of Moodmetric?

I thought it’s similar to the Mood Ring from the 70s! After seeing the first demo I realized that it has much more dimensions than that. The technology inside the ring, and the user interface was really convincing and got me really interested about the project.

Have you been interested in combining technology to jewerly before?

Tecnology in our daily lives has increased and it has brought challenges not only related to usability but also how wearable the tech actually is and what is the message it delivers. How do the equipment and gadgets modify our wardrobe and style? Do we want to look like cyborgs or hide the tech? The tech is coming to dressing, jewelry and fashion.

The tech is coming to dressing, jewelry and fashion

People have used jewerly for about 7000 years and reasons to wear them have changed over centuries. The common factor has always been a personal relationship to the jewel and especially memories associated with it. Today, if we want, the tech enables saving the memories and data very concretely. The jewel itself can measure our bodily functions and quality of sleep, it can store pictures and moments that can be shared with others.

For me as a designer it is extremely intriguing to have a possibility to make jewels that can protect us, improve our wellbeing and health, and add quality to our lives.

What were the main things to consider when you started working with the design?

My aim was to create a jewel without highlighting the technical function

The starting point for the Moodmetric Ring design was the technology inside: electronics assembly and conductive rings, and equally usability and manufacturability. My aim was to create a jewel without highlighting the technical function. The purpose was to make a ring that the wearer wants to use in her everyday life.

What was the most difficult constraint dictated by the tech part of the ring? How did you solve it?

It was very challenging to have the ring fitting to everyone: everyone´s fingers are of different size and shape, and the measurement is very exact requiring the contact to be constant. One-size-fits-all was out of the question, as well as very wide selection of sizes. But we came out well, with a good fitting and measurability for everyone.

How do you see the future of smart jewerly? How you think the technology will affect the jewerly market? Are there some other trends in jewelry market that are upcoming?

I strongly believe that jewelry will have more functions in the future, they will not remain just decorative items. They can be equipment that link to personal wellbeing, to relationships with others or to the health and medical systems.

In ancient times the jewelry often had mystic healing or protective powers related to them by folklore that are now here for real.

You are doing a thesis work at the moment, and Moodmetric is a part of it. Can you tell shortly what is it about?

The Moodmetric project lit up my interest on the topic: design, handicraft, technology and the possibilities coming from combining them in future jewerly. I have over 20 years of experience of silver/goldsmith work as well as a designer and a craftsman.

Jewels and other personal objects should reflect the thoughts of the user, not the designer

Designing jewels is very close to telling silent stories and describing emotions. A jewelry designer tries to give a form to something we think or feel or create in us emotions that we want to share. And which we want to wear! Designing jewels is and art form that does not forget usability, unlike industrially designed everyday objects where “form follows emotion”.

I compare designing jewels to composing music: when the result is successful it is like a good piece of music that becomes a part of our lives and raises emotions in us.

Having so many things around us today, the desirability of a product is defined by how it resonates with us, what story it tells to us. “Idea of craft” is more and more essential in designing products with other aspects than usability. Jewels and other personal objects should reflect the thoughts of the user, not the designer. What I will bring up in my thesis work is especially the idea of combining humanity and individuality to technology products. I want to add some “soul” to technology!

Startup developing a hardware product

mock-up_transparent_background

Productizing means bringing a new product, service or feature from an idea to a commercial product. Even something seemingly simple, say a shovel, needs countless steps from the first sketch to a shop.

The Moodmetric Ring is an embedded system, i.e. an equipment guided by an in-built computer, in this case a processor. It has required the development of the measurement system, the ´computer´ and the software guiding the measurement. All this is a significant amount of work in addition to building up the hardware of chosen components.

When a product, new version or feature is developed inside an existing organization, the resources are in place: you have the hardware development department, software/embedded software development department, prototype production line and a test laboratory filled with equipment specific for the needs of the particular industry.

In a startup there is normally nothing at all, just an idea. How is a complex development work possible?

The most important thing is the team: everyone should be top-tier and know absolutely the latest of relevant technology. There are no bosses or internal audits, all issues need to be discovered and managed within the team. For a product like the Moodmetric ring the knowledge of signal processing, biosensor technology, algorithm development and software development have been in great hands, which has enabled a leap that is hard to believe even when seeing it happening next to me.

There need to be third parties involved, small electronics and manufacturing shops for prototyping and development. A good network of local SME tech industry is always needed when starting of development of any device. Due to our backgrounds in engineering and manufacturing, this has been well covered.

The most important thing nro 2 is the customer. Which in the beginning is not yet there. The search for the customer needs to being at the same time as the idea of a product first crosses the inventor´s mind. Where, who? A startup likes often to keep the invention secret as long as possible, which certainly is wise. But without a customer feedback, the product will not hit it.

We found the initial customers very early. Then we found more customers, totally different demographic and market. And more.. This is maybe the most confusing time period: you develop the product, you make prototypes, you ask the customer opinions and all the time you are insecure are you heading to the right market. We just had to continue and take decisions on the way until we felt this is getting right.
A very important concept is the minimum viable product Eric Ries: The Lean Startup. This is the first concept to test with a real user, and does not have to look like the final product at all. Ours was like this:

For an architect an MVP can be a cardboard box and for a computer game developer a sketch. Just to test the initial idea and start collecting feedback from early on.

We have all worked in big organizations and it is very refreshing to develop a product in a startup mode. Again, no bosses, no internal audits, no bureaucracy (except for what you decide to implement), nothing formal, only the common objective and total freedom around it. When things are getting ready and there are more people and parties around, the freedom gradually gets less. Suddenly a startup realizes being a big organization and someone asks you to report your workhours in the ‘system’.

Moodmetric has decided to stay lean and follow the teachings of Vincit. Quoting their CEO Mikko Kuitunen: “When the headcount goes over 30, the people still remain intelligent enough to decide whether they need to buy a pencil or not.”

 

 

Where to measure electrodermal activity?

This article explains the difference of using a wristband or a ring to measure your emotional intensity levels.

Moodmetric rings

Many things can get you emotionally activated. A close by situation with a colliding car can certainly light all the inner alarm systems, but milder things can also cause strong emotional reactions: seeing your children after a school day, a victory of you favourite basketball team or forgetting to buy paper for your printer.

With any emotional activation, your skin reacts and becomes a better conductor of electricity. This can be resulting from emotional or other psychological causes. The phenomenon is known as the skin conductance response or electrodermal activity (EDA). You may also run into an older term called galvanic skin response.

Based on the scientific research there are only a few places in your body where the EDA can be measured accurately and easily: the palms and the soles of your feet. These are the places where human body has the highest density of eccrine sweat glands that response to the emotional stimuli. You can measure the EDA elsewhere as well but the reliability is not as high or as easily achieved.

We want to bring to the market a very reliable and accurate measurement of emotional activation and intensity that is available for everybody. The choice for having a beautiful jewelry ring as the measurement form was an easy one.

It provides the best optimal measurement data that can be detected from the palm side of wearer’s hand. A ring is also a natural thing to wear and can be used daily as any other jewelry. It is easy to forget that this small, beautiful and non-intrusive jewelry detects your emotional levels and helps you in your life with its data.

Moodmetric features: Scope and Wearing the ring

MoodScope curve

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”

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.
