本文研究了视觉线索如何影响人类在画线任务中的表现。画线是一项原始且基本的任务，需要使用钢笔、（烙铁）和切割器等工具。许多情况（例如家庭、办公室、工作室和车间）需要使用工具绘制线条。用于提高绩效的辅助工具对于不熟练的人可能特别有用。第一步，我们将视觉线索作为辅助工具，并确定对良好表现有效的视觉线索类型。我们要求受试者在显示的虚线上画一条线，同时改变点的间距和形状，然后我们分析数据。结果表明，表现良好时应显示的提示应根据受试者的表现而变化：对于表现良好的人，应显示几何中心易于检测的提示；对于表现不佳的人，应显示占用面积较大的提示。我们还讨论了控制画线性能的可能性，并提出了一种显示视觉提示以获得良好画线性能的策略。
This paper investigates how visual cues affect human performance at a line drawing task. Line drawing is a primitive and fundamental task using tools such as pens, (soldering) irons, and cutters. Many situations (for example, home, office, studio, and workshop) require drawing lines with tools. Assistive tools for improving performance might be especially useful for unskilled people. As a first step, we focus on visual cues as assistive tools and determine the kinds of visual cues that are effective for good performance. We asked subjects to draw a line on a displayed dotted line while the spacing and shape of the dots is changed, and we then analyzed the data. The results indicate that the cue that should be displayed for good performance should change according to subjects' performance: for good performers the cue whose geometrical center is easy to detect, and for not-good performers the cues whose occupied area is large. We also discussed the possibility of controlling performance in line drawing, and presented a strategy for displaying visual cues for good line drawing performance.
