In our previous paper, we reported the three-axis tactile sensor worn by human fingernail to record distinguished person’s manipulation. The tactile sensor is based on fingernail color change caused by applied force. In this study, we examine the sensing precision of tangential force, which is frequently caused by tasks of nursing and ceramic art. In the experiments, 10 human subjects wore the tactile sensor on their index fingertip to vary direction of tangential force from 0° to 360° in 30° increment. Then, CNN learned fingernail image data associated with three-axis force components. As result of this learning, maximum error of tangential force direction was 5°.
