The transition from on-site crane operation to teleoperation in cargo port operations has introduced several challenges, including the loss of sensory information. This study aimed to address this issue by restoring operators' sensory input using multimodal aids, specifically haptic and auditory modalities. The haptic modality involved force feedback, while the auditory modality consisted of two separate sounds that played faster and louder depending on how well the crane handle was lined up with the truck or drop-off spot on the boat. The study compared the use of force feedback and auditorial modalities in isolation from each other, as well as in combination with each other, and found significant differences in task performance and user experience. The findings indicated that the force feedback in combination with auditorial cues as one multi-modality platform helped operators to work more quickly and with better accuracy; however, this was at the expense of an increased number of moderate and severe collisions. Additionally, force feedback was perceived as the most enjoyable and intuitive modality to use. Other modalities were either deemed irritating, challenging to use, or did not aid in terms of completion times, collision avoidance, or stacking accuracy. This study provides valuable insights into the effectiveness of multimodal aids in enhancing teleoperated cargo port crane operations.
