This study considered animated manuals among the assembly manuals used in the manufacturing industry, which is one of the important components for enhancing service productivity in the task teaching process. In particular, it focused on information that pertained to the worker’s hands. The objective of this study was to investigate the impact of the inclusion of hand information for assembly workers and to elucidate on the effectiveness of the provision of hand information in assembly manuals. The subjective experimental results from four participants demonstrated that hand information was beneficial either when the presentation of such information was sufficiently easy for users to comprehend or when unstable parts have to be held by the hands.
