Do you study stress, customer experience, attention or decision making?

The Moodmetric measurement gives accurate and real time data on cognitive and emotional load of an individual. Use cases below give a snapshot on what kind of research it can be applied to. These are just a handful of examples. Electrodermal activity is a signal with great and for most unused potential in field research.

Stress

Positive stress is a good thing and when in control, it takes us forward. Chronic stress reduces productivity, creativity and job satisfaction and it is a risk for physical and psychological health. It is not easy to catch signals early and stress might not be detected before it has reached harmful levels.

Questionnaires are subjective and bound to a certain moment. Preventive stress management needs continuous and long term measurement. The Moodmetric ring is intended for weeks and months of use. The mobile app offers a real time view which enables insights that can be actioned immediately.

Even though the Moodmetric measurement is primarily intended for use at occupational health, the real time measurement enables several kinds of research. Below are some example use cases to give a picture of it´s possibilities:

Customer experience

A customer is testing a new shopping center virtually. The center is equipped with innovative implementations, including parking, navigating inside the center, paying in the shops (only mobile payment) etc. The pilot customers´ opinion have a major significance on the final drawings and the pilot is heavily studied. The Moodmetric measurement shows instantly and in real time the pain points – when the experience is getting from smooth to troublesome. The Moodmetric levels increase in seconds when the customer is perplexed.

A much simpler example would be e.g. driving through a car washing lane. How many of the customers actually get terrified inside, with not way of getting out in the middle? Could this be eased out somehow?

The Moodmetric measurement can be used to tracking stress levels in any environment, inside or out in the woods. It suits to observing a person in different situations, like choosing clothes. Which print makes the person react?

Gaming

Mobile and desktop games can be extremely agitating. Chasing, fighting, racing and performing dangerous tasks is enervating. The sympathetic nervous system of the player is active, as the body does not understand that the threat is just an illusion created by the game developer.

A game can also be soothing, like puzzles. Focus is needed but vigilance not.

What kind of a game is yours and what is the target audience? What if you could design games that really calm down the sympathetic nervous system – a game that you could wholeheartedly recommend e.g. for kids with concentration difficulties?

Pay attention!

We make better decisions, our movements are correct and precise, and we make better analysis when we pay attention. Really pay attention by not letting noises, lights, phone, emails or the smell of lunch distract us.

The Moodmetric index of 1 to 100 tells our arousal level. When focused, the level is below 30, in most cases below 20. Full focus on the task at hand might show a steady level of 12 with almost a straight electrodermal activity curve on the Moodmetric mobile app. The person is far from being sleepy (although in the evening at the sofa the numbers might be exactly the same), but fully focused.

This does not necessarily need an isolated environment. Most people can find their way to reach focus no matter the surroundings. But as it is not easy, many companies design spaces and areas inside their offices that enhance concentration.

Sports

What kind of training methods provide the best results? The Moodmetric measurement makes it possible to better understand what level of focus the athlete reaches. Interventions such as mental exercises can tested and found out the ones with the best results for improving concentration. The measurement also provides insights as to when recovery from practice is sufficient. The app diary helps to analyse which activities should be toned down or avoided in order to benefit optimally from training.

Electrodermal activity measured by the Moodmetric ring

Electrodermal activity

With any sympathetic nervous system activation, skin reacts and becomes a better conductor of electricity. This can result from emotional, cognitive or other psychological origin. The phenomenon is known as electrodermal activity (EDA) and it is widely adopted in psychological research (1). Other commonly used terms for this phenomenon are skin conductance response and galvanic skin response.

EDA is generated by the 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 eccrine sweat gland density (2). You can measure EDA elsewhere as well but the reliability is not as high or as easily achieved.

The unconscious actions of the human body are regulated by the autonomic nervous system. It consists of the sympathetic and parasympathetic part. The parasympathetic part controls the body’s rest-and-digest functions and the sympathetic part controls the fight-or-flight reactions. By examining electrodermal activity we can understand the sympathetic nervous system reactions.

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 cognitive and emotional arousal, and high responses are caused by e.g. stress, enthusiasm, anxiety, joy, anger (1, 3).

Mobile EDA devices have been used by scientists for some time (2, 4). The Moodmetric ring is an unobtrusive option to follow EDA responses real-time and in long term.

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

The Moodmetric measurement accuracy has also been studied at the University of Tampere, Finland in 2014. The correlation with the reference equipment Nexus-10-MK II was good. Comparison details in charts below.

With skin conductance level (SCL) we refer here to raw measured skin conductance without any filtering. The figures below show the comparison of the two devices.

Moodmetric at Emotion Hack Day

 

Emohackkollaasi

The University of Helsinki celebrated its 375th anniversary with the Helsinki Challenge competition, that was launched in 2014.

The competion received more than 140 registrations, and after a long selection process – including startup-type pitching –  the winner was selected at the end of 2015.

NEMO – Natural Emotionality in Digital Interaction,  received €250,000 for realising the team’s idea: to add empathy to the internet.

Digital systems are not designed to consider emotions. As a result, the tools we have for expressing our emotions online are severely lacking in quality. This in turn inhibits empathy, the mechanisms that allow people to understand each other, connect and collaborate.

The research team including Katri Saarikivi, Tommi Makkonen and Valtteri Wikström have a huge task in front of them. Part of their project is to include others with events like the Emotion Hack Day, that Moodmetric was also invited to participate.

The event took place simultaneously in Helsinki and Montreal, and gathered talented people from all work backgrounds to spend 24 hours to generate ideas around digitalizing emotions.

Moodmetric sponsored the event with the Moodmetric rings and SDKs for teams interested in using GSR in their project:

‘It is always fun to work with a new wearable technology and think of how it can be leveraged in every day life. Also, working with a company that takes pride in making the data interface easy to work with is refreshing, since it allows us to focus on the creative aspects, instead of the device interface.’  -André

The submissions are one step towards online presence – with emotions.
