The remote operation of underwater vehicles at depth is complicated by the presence of invisible and unpredictable environmental disturbances such as cross-currents. Communicating the presence of these disturbances to an operator on the surface is made more difficult by the nature of the disturbance and the lack of visible features to highlight in the visual display presented to the operator. Here we explore the use of a novel interactive soft haptic touchpad that utilizes vibration and particle jamming to provide information about the presence and direction of cross-currents to the operator of an ROV (remotely operated vehicle). An in water experiment using a thruster-based ROV and artificially generated cross-current was performed with non-expert ROV operators to evaluate the effectiveness of multimodal haptic feedback to communicate complex environmental information during high-risk operations. Advanced haptic displays can signal both the presence of external factors as well as their direction, information that can enhance operational performance as well as reduce operator cognitive load. Using haptic feedback resulted in a statistically significant reduction in cognitive load of 24.3% and increase in positioning accuracy of 28.3% for novice operators. Deviation from an ideal path was also reduced by 29.5% for experienced operators when using haptic feedback compared to without. While this experiment took place in controlled conditions with a fixed direction cross-current and haptic interface, this approach could be extended to communicate real-time environmental information in real-world unstructured environments.
