Japanese companies are developing technologies to enable them to visualize human feelings and emotions by analyzing reactions in their brains.

Konica Minolta created a mathematical model based on data it collected with researchers from Hiroshima University.

The company says the technology can visualize in colors and numbers what impressions people have when they see product labels or advertising. It can also pinpoint what areas people notice. It is expected that the technology will be used in product development.

Inoue Satoru of Konica Minolta says, "This will help create designs and marketing materials that can catch consumers' eyes more efficiently."

And Mitsubishi Electric has developed a sensor that can quantify concentration and fatigue by measuring a person's pulse waves and analyzing brain activity.

The company plans to use the data to ensure better working conditions and the welfare of its employees.
