There are two types of personality test methods in common use: verbal and non-verbal, each with its advantages and disadvantages. If a new personality test method that can compensate for the disadvantages of both methods is developed, it would be used worldwide. To develop a new method to estimate human personality, we have attempted to measure human motions using the optical motion capture system (OMC) and group them by feature points. However, it was found that OMC is inconvenient due to camera calibration and attachment of infrared markers to subjects. In this paper, to make it more efficient, we compared OpenPose, which can detect the position of human joints with a video camera, to OMC. As a result, it was confirmed that OpenPose is more effective than OMC in analyzing human motion. In addition, we attempted transfer learning for classifying test scores of a personality test based on “Big Five personality traits” from walking trajectory graphs from OpenPose.
