The Influence of Target Layout and Clicking Method on Picking Time and Dragging Performance Based on Eye-Control Technique

Abstract

Eye-tracking has been a hot topic in human-computer interaction (HCI). Nevertheless, previous studies usually adopted eye-tracking as information output rather than input. The eye-control technique can achieve convenient and rapid real-time operation through the movement of the eyes and reduce unnecessary manual operations. Because the layout determines the location orientation, organizational complexity, cognitive consistency, and predictive ability of the information display, the interface layout design affects the user's perception of information intensity, complexity, and logic. Moreover, the method of target clicking by eye-control techniques, which include blink and dwell, also depends on the application and user's ability. The purpose of this study is to investigate the influence of target layout and target picking method on picking time and dragging performance based on eye-control technique. The results indicate that the target picking method, i.e., blink or dwell, had significant effects on the dragging time and dragging numbers. However, there was no significant effect of target layout on picking time and dragging performance (dragging time and numbers), which may be related to the setting of the experimental conditions (e.g., lighting level and screen resolution). Moreover, the target picking method and the target layout had no significant interaction effect on picking time and dragging performance. The findings are anticipated to provide helpful implications for future eye control technique design.

The influence of target layout and target graphic type on searching performance based on eye-tracking technology

“…In their work, the mouse and eye-tracking data were gathered by monitoring the operators who were using the control panel to develop several predefined tasks, and the optimal layout was obtained by using a genetic algorithm. Wang et al (2020) used eye-control technique to investigate the influence of target layout and target picking method on picking time and dragging performance. Kanaan and Moacdieh (2021) studied whether the differences in the eye movement led by the display clutter in the website layout could be detected in the first few seconds of a search task using a realistic display, both with or without time pressure.…”
