We created “Mind Loop Technology”, which utilizes the user’s brain waves to estimate her emotions and generate VR images that changes her mood which in turn generate new images in a feedback loop. At Tokyo Game Show 2016 the Dentsu Science Jam booth showcased 2 products: “Kaleido Therapy” which relieves stress through a kaleidoscope of images, and “Brain Wave Love Checker” which measures interest based on VR scenarios.

“Kaleido Therapy” is a functional VR content which utilizes “Mind Loop Technology” to quantify the user’s emotional states. It is under development jointly by DG Lab and DSJ.
Kaleido Therapy calms the user by estimating stress level with her brain waves and changing the VR Kaleido Image in response to the stress level. Through our previous evaluation experiment, we find that 88% of our 43 test subjects managed reduce their stress levels.

■ Supervising Director Koji Yamami (Kaleidoskop Artist)

Born in Tokyo in 1961. After he learned the art of stained glass, he was surprised to see full-fledged kaleidoscopes in America and started to make them. In 1995, he joined the Brewster Kaleidoscope Society. He became the first Japanese artist who participated in the convention in America, and received the best award in 2001, 2003, and 2013. He is the premiere kaleidoscope artist in Japan, with unique and beautiful artworks that has garnered him many avid fans.

■ Applying the “Emotion sensing algorithm” from Dentsu Science Jam

The algorithm is based on the research output of our CTO and Keio University professor, Mitsukura. She has spent 16 years researching the estimation of human emotions through brain waves. The algorithm can objectively evaluate how people feel and in this VR project, we use part of the algorithm which can extract five states: “interest”, “liking” ,”focus”, “drowsiness” and “stress”.

With this product, we show the user 3 different women and estimate the interest and preference level through the user’s brain waves. At the end, the Brain Wave Love Checker will automatically select the one the user liked the most. We envision a multi scenarios VR image system that branches out according to the brain wave results.
