“…However, this does not indicate a significant performance improvement. This phenomenon has been reported in studies on the effect of time pressure on HCI task performance [ 51 ] with potentially effective solutions, such as the use of assisted decision-making systems [ 52 ]. We found that time pressure significantly increased the error rates in all three levels of task difficulty, with or without the use of touchscreens.…”

“…This may be attributed to the negative effect of time pressure on participants’ performance. Time pressure had a greater effect on participant performance than task difficulty [ 51 , 53 ]. Because low-difficulty tasks provide detailed operational cues (instructions on how to handle errors) and the corresponding time pressure is highest for low-difficulty tasks, we hypothesized that providing detailed information under high time pressure would increase error rates, and that a detailed information display is not always an efficient information delivery feature.…”

The suitability of touchscreens for human–computer interaction in manned/unmanned aerial vehicle cooperative missions remains uncertain, especially in situations that are time-sensitive with variations in difficulty levels. The purpose of this study is to determine the feasibility of touchscreen applications in manned/unmanned aerial vehicle cooperative missions and the magnitude of the effects of time pressure and task difficulty. In contrast to previous studies, a combination of performance and perceptual load measures was used to divide errors into disposition errors, undetected errors, and miscalculation errors to explore specific error mechanisms, set up typical manned/unmanned aerial vehicle cooperative human–computer interaction tasks, and set up antecedent features for potential factors. Thirty subjects participated in an experiment that required the use of touchscreens or keyboards to perform a human–computer interaction task in a simulated manned/unmanned aerial vehicle cooperative mission. Experiments were set at three task difficulties: low, medium, and high, and were matched to a set time pressure or no time pressure for two seconds for low difficulty, three seconds for medium difficulty, and four seconds for high difficulty. The results showed that the touchscreens improved the participants’ response speed at a time pressure of 2 s or less compared with the use of a general input device; however, the task error rate also increased significantly. The higher the task difficulty was, the worse the performance was and the greater the perceived workload of the participants. The application of touchscreens in dynamic environments subjected the participants to greater physical demands. The performance of participants using a keyboard was no better than that when touchscreens were used during the experiment. Moreover, touchscreens did not significantly improve participant performance. The results support the possibility of using touchscreens in manned/unmanned aerial vehicle cooperative missions.
