Most of the problems we face in our life have already been experienced and solved by others. In this research, focusing on this point, we realize human-machine harmonious collaboration by recording experiences as digital data, store them in “experience bank” for their distribution. In this process, we transform the digital record of experiences into a user-adapted form called “experiential supplement” taking into account users’ cognitive biases. This makes the experiences more acceptable by users to change their behavior. We demonstrate the effectiveness of the above process in the fields of learning, health care, sports and entertainment.
