地图导航类APP半透明黑色蒙版的透明度阈限研究

Study on Transparency Threshold of Translucent Black Mask for Vehicle Information Entertainment Terminal

探究地图导航类APP半透明黑色蒙版的透明度阈限。将某导航APP界面原型作为实验研究对象,使用眼动仪进行测试,对眼动扫描路径和热点图进行分析得到半透明黑色蒙版透明度阈限的下限,并通过系统可用性量表评估半透明黑色蒙版的可用性得到半透明黑色蒙版透明度阈限的上限,结合两部分的实验从而得出半透明黑色蒙版透明度阈限。为了保证半透明黑色蒙版的可用性和良好的用户体验,透明度应保证在40%~60%的范围之内,在60%的情况下,用户对主体内容的注意力最高。在排除主体内容与背景对用户的视觉影响的情况下,用户在半透明黑色蒙版透明度为40%~60%的范围内可以让用户将视觉注意力集中在主题内容的同时,让用户了解自身所处的环境,给予用户良好的体验。

Objective Improve the user＇s experience on the use of the vehicle information system interface. Method The prototype vehicle information system as study object, to test the use of eye tracker, analyze the lower bound obtained by translucent black mask transparency threshold of eye movement of the scanning path and hotspot map, and through the system usability scale usability evaluation of black mask are translucent translucent black mask transparency threshold limit, the combination of the two part the experiment obtained translucent black mask transparency threshold. Result In order to ensure the usability and user experience of translucent black masking, transparency should be guaranteed in the range of 40%～60%. In the case of 60%, users have the highest attention to the content of the main body. Con-clusion The main contents and background in the exclusion of visual effect on the user＇s case, the user in the translucent black mask transparency can be in the range of 40%～ 60% to allow users to focus on the theme of visual content, allowing users to understand their environment, give the user a good experience.
