Mood tracking for Self-Reflection 


Insomnia is the regular occurrence of the inability to sleep. 33% to 50% of the adult population experience insomnia. Insomnia symptoms include: sleepiness during the day, increased stress levels and emotional instability, reduced creativity and memory, concentration problems and fatigue. All these symptoms lead to a set of moods caused by insomnia. These moods, in turn, contribute to rumination during the night which can lead to insomnia. In this way, an uninterrupted cycle is started. Where insomnia leads to moods during the day and moods lead to insomnia during the night.


Suru breaks the cycle. 

Suru is a mood tracking device that lets the user release the energy of their mood by creating cracks in the Suru stone. The cracks of the stone will slowly start to heal after an interaction. If the mood is still not gone the user can reinforce the cracks. The more severe the mood is the user can release this mood by creating more cracks. More cracks means also a longer healing time. 


When the user creates cracks in the stone the location, time and duration of the interaction will be saved. This data enables the user to track their progress, self-reflect and do pattern recognition. This information could also help with Cognitive Behaviour Therapy for Insomnia (CBTI).
