Collective Happiness and Teaching
We have measured massive collective human behavior data for over 1 million days using wearable sensors with 20-ms fine resolution. The data are measured at stores, warehouses, software houses, hospitals, care centers, call centers, schools, etc. By using this data combined with questionnaires, we have discovered that the diversity of physical-motion length in a group predicts group-level collective happiness of people. The questionnaires ask how much happiness, enjoyment, loneliness, sadness etc. one experienced past week. Tabulated scores strongly correlate with diversity-of-motion index (r=0.94.) Because services, such as call centers, stores, and warehouses, are operated by many part-time workers, their productivity is supposed to be determined by how to skill up the fluid workers in a short time. However, the productivity, in fact, is strongly influenced by the collective happiness, or the diversity of motion in a group. This shows that the process of enhancing the capability of people is not just a transfer of knowledge and skill, but, in fact, is closely related to collective happiness of people. Education process of children is also analyzed based on the same method, which has revealed strong relationship between the test score and the collective physical motion.
