Abstract In order to correctly read and interpret interface information shown on the interface of vital signs monitor, the challenging problems of misreading and misinterpreting the information must be addressed. Therefore, a visual search experiment that the text characteristics of the interface is carried out in this study to categorize parameterized information and encode parameterized numbers on a monitoring interface. The interface of a centralized vital signs monitor is simulated, and target searching of information objects is carried out in an experiment with three sets of characteristic variables: font size, background and text color, and spacing and location of the parameterized information. The experimental results show that the relative spacing of the information elements on the interface should be not too large or small. When the spacing is 30px, 38px, 46px, and 86px, the visual search process requires a long period time and it is easy to misinterpret the information. With an increase in the spacing, the plotted visual search response to different font sizes is a V-shape, while the rate of accuracy becomes an inverted V-shape. Compared to a font size 35pt and 55pt, a font size of 45pt results in the highest search efficiency and rate of accuracy. However, the background color has no significant effect on target searching in terms of reaction time. The findings show that the results in this study can be used as a guideline for the interface design of visual monitoring systems with diverse characters and spacing.

生命体征监测界面文字特征视觉搜索实验

摘要 为了正确读取和解释生命体征监护仪界面上显示的界面信息,必须解决误读和误读信息的挑战性问题。因此,本研究进行了界面文本特征的可视化搜索实验,对监控界面上的参数化信息进行分类,对参数化数字进行编码。模拟集中式生命体征监护仪的界面,在实验中使用三组特征变量进行信息对象的目标搜索:字体大小、背景和文本颜色以及参数化信息的间距和位置。实验结果表明,界面上信息元素的相对间距不宜过大或过小。当间距为30px、38px、46px、86px时,视觉搜索过程需要很长时间,容易误解信息。随着间距的增加,绘制的对不同字体大小的视觉搜索响应为V形,而准确率则变为倒V形。与 35pt 和 55pt 字体大小相比,45pt 字体大小的搜索效率和准确率最高。然而,就反应时间而言,背景颜色对目标搜索没有显着影响。研究结果表明,本研究的结果可以作为具有不同字符和间距的视觉监控系统界面设计的指南。随着间距的增加,绘制的对不同字体大小的视觉搜索响应为V形,而准确率则变为倒V形。与 35pt 和 55pt 字体大小相比,45pt 字体大小的搜索效率和准确率最高。然而,就反应时间而言,背景颜色对目标搜索没有显着影响。研究结果表明,本研究的结果可以作为具有不同字符和间距的视觉监控系统界面设计的指南。随着间距的增加,绘制的对不同字体大小的视觉搜索响应为V形,而准确率则变为倒V形。与 35pt 和 55pt 字体大小相比,45pt 字体大小的搜索效率和准确率最高。然而,就反应时间而言,背景颜色对目标搜索没有显着影响。研究结果表明,本研究的结果可以作为具有不同字符和间距的视觉监控系统界面设计的指南。背景颜色在反应时间方面对目标搜索没有显着影响。研究结果表明,本研究的结果可以作为具有不同字符和间距的视觉监控系统界面设计的指南。在反应时间方面,背景颜色对目标搜索没有显着影响。研究结果表明,本研究的结果可以作为具有不同字符和间距的视觉监控系统界面设计的指南。
