Abstract
The maker movement, i.e., the culture of do-it-yourself technology, is spreading worldwide from the United States. The application of physical computing and digital fabrication on the development of biofeedback devices, as well as the influence and effects of such processes on future research, were explored. Examples of entertainment-oriented biological information measuring devices were showcased, and the importance of learning the psychosomatic relationship through play were emphasized. By becoming familiar with device development and applying that to educational activities, the possibility that biofeedback generalize and spread more widely to our life was proposed.
