Positive Effect of Slight Delay and Task Conditions for Operational Performance

We have hypothesized that providing the control system with an appropriate delay would improve its operational performance. Previous experiments in our laboratory have suggested that slight delay in the operation of a tool improves operational performance. However, another experiment with slight changes in appearance and task details did not show positive effects. In this study, we investigated the requirements for slight delay to improve performance. By adjusting the task while keeping the appearance unchanged, we again obtained results suggesting an improvement in tool operational performance. The effect of the difficulty of the operation task was also inferred.
