Bio-information presenting device and bio-information presenting method

A bio-information presenting method and a bio-information presenting device, for presenting the bio-information, indicating the movement of a physical organ of a user, for the user, are disclosed. The movement of a bodily organ of the user, controlled voluntarily or involuntarily, is fed back to the user. A background image is stored in a storage unit for image data for composition 5. An image processing unit 6 compounds an image of the user, captured by a camera 8, with a background image. In compounding the images, the image of the user is subjected to fade-in and fade-out in association with an output of a breathing sensor 7. The user is apprized of the inhalation period, exhalation period and the depth of breathing, based on an image demonstrated on a display unit 10. The change in the display image surface produces certain changes in the user's breathing. The display unit 10 of the breathing visualizing device 1 is changed responsive to the breathing of the user. A feedback loop is formed in this manner between the breathing visualizing device 1 and the respiratory organ of the user.
