A Comparison of Visual Occlusion Methods: Touch Screen Device vs. PLATO Goggles

摘要: Objective: This study compares two visual occlusion methods for the evaluation of in-vehicle interfaces. Background: Visual is a demand measuring technique which uses periodic vision/occlusion cycle to simulate driving(or mobile) environment. It has been widely used There are major implementation this technique: (1) using PLATO(portable liquid crystal apparatus tachistoscopic occlusion) goggles; (2) software application on touchscreen device. Method: An experiment was conducted examine an interface prototype goggle-based and touchscreen-based methods. Address input radio tuning tasks were evaluated in experiment. Results: The results showed that, task, there no significant differences total shutter open time resumability ratio between conditions. However, it took longer participants addresses with occlusion. Conclusion & Application: suggest that method could be as alternative traditional, gogglebased especially less demanding such tuning.
