The Okajima Laboratory was established at Yokohama National University in April 2004. Human brain information processing with a central focus on visual processing is being studied and Virtual Reality,Augmented Reality, Information Display, Computer Graphics, Color Processing, and Welfare Information Systems in light of human factors are being developed. In addition, we are simulating and developing intelligent systems for human interface. I should say that brain science is a goldmine in developing breakthrough technology. Join us to study out the mystery of the brain and to create new engineering applications!

The human brain is the most complex system for information processing. As a result brain science is typically an interdisciplinary field, involving mathematics, physics, psychology, medical, informatics and neuroscience. We are mainly interested in trying to understand the "secret" of the brain through Psychophysics as a research method. Psychophysics is a powerful tool for investigating a "black-box" such as the brain and the sensor systems of a human being.
