Effects of different visual feedback mechanisms on eye-controlled interaction in a vibration environments

Abstract: Eye-controlled interaction is a human-computer interaction technology that users can complete the interactive behavior by moving eyes to control equipment or devices, which has the advantages of human-centered, natural and direct. During the process of eye-controlled interaction, effective visual feedback mechanisms can help users accurately understand the operation process. A vital part of eye-controlled interaction is to confirm the user’s intent to select the target character, so it is important to study the effects of different visual feedback mechanisms under the selection task. However, there is a gap between lab environment and real-world application, that contain vibration environment. This study aimed to compare the performance of different visual feedback mechanisms in vibration environments. 20 participants are required to complete the selection task of time delay selection mechanism and selection sub-selection reconfirmation mechanism in three states: static, low vibration, and high vibration environments. The results indicate that the various visual feedback mechanisms have distinct impacts on selection accuracy. Regardless of the vibration environment, the accuracy of the time delay selection mechanism surpasses that of the selection sub-selection reconfirmation mechanism; Vibration exerts an adverse influence on visual fatigue, with more intense vibration leading to a shorter occurrence time of visual fatigue. The time delay selection mechanism is a widely favored visual feedback mechanism, offering a lower subjective workload.
