EMOSy makes it easy to measure emotions🥳
EMOSy (EMOtional States measurement sYstem) is an emotion measurement system that uses emoji (e.g. 😀). EMOSy allows you to easily record your mood by selecting an emoji that matches your mood on an IoT device such as a smartphone or smartwatch. You can also record information such as the time and place where you selected an emoji, as well as vital information such as your heart rate. So, you can know "when, where, what you were doing, and how you were feeling" over time.
Using scientific evidence-based emotion measurement, applying from global-scale research to business🤗
EMOSy can conduct scientific emotion measurement and analysis based on the results of emoji surveys conducted with over 4,000 people. It can also be used in various situations related to human emotions, such as measuring satisfaction with events or evaluating office environments, regardless of various attributes (e.g. age, gender, etc.). Furthermore, EMOSy can be used not only by Japanese people, but also by people from other countries and cultures (scheduled to be launched in Germany, South Korea, and Switzerland* in March 2025). To measure psychological states other than emotions (e.g., stress, or well-being), you can also use Likert scales etc.

Research Background
Why should we use EMOSy🧐？
To measure emotions in everyday life, it has been necessary to repeatedly answer questionnaires with scales or open-ended questions throughout the day, making it difficult to capture emotional fluctuations in detail. Therefore, we thought that selecting emojis to report emotions would make it easy to collect a lot of data, which is why we started to develop EMOSy.
The advantages of using emoji are: 1) they can be recognized intuitively; 2) they are not language-dependent, so they are less affected by age, culture, etc.; and 3) emoji are easy to implement regardless of the type of IoT device, such as smartphones or smartwatches.
However, there was no scientific evidence that emoji could be used as an indicator of emotion. In developing EMOSy, we first clarified that emojis correspond to a variety of human emotions. Then we made it possible to scientifically analyze how each emoji differs, confirming the validity and reliability of the research method. In addition, EMOSy can capture emotional fluctuations in daily life with a higher reporting rate than traditional methods of measuring emotions.
Therefore, EMOSy, as a new form of emotion measurement, allows us to better understand human emotions.
