论文摘要

虚拟现实(VR)通过创建复制或增强增强现实生活中的不同应用程序,对从教育,医学到工程和娱乐的许多领域的市场产生越来越大的影响。 VR应用程序打算展示现实的环境,包括我们每天都包围的文本。但是,如果文本以用户可以舒适地阅读它的方式设计和创建虚拟环境,则只能为虚拟环境增加价值。为了探索用户在虚拟现实中阅读时舒适的文本参数值的目的,进行了一项研究,使参与者可以操纵文本参数,例如字体大小,距离和对比度。因此,使用了两种不同的独立虚拟现实设备,Oculus Go和Quest以及三个不同的文本样本:简短(2个单词),中(21个单词)和长(51个单词)。参与者的任务是将文本参数设置为最佳和最差的价值。此外,要求参与者评估他们在虚拟现实中阅读的经验。结果报告了角度大小(距离和字体尺寸的组合)和颜色对比度的平均值,具体取决于所使用的不同设备以及不同的文本长度,用于两个任务。根据显示的文本的长度,发现角度大小值的显着差异。但是,不同的设备类型对文本参数没有显着影响,而是对使用自我评估Manikin(SAM)量表报告的经验。

Virtual Reality (VR) has an increasing impact on the market in many fields, from education and medicine to engineering and entertainment, by creating different applications that replicate or in the case of augmentation enhance real-life scenarios. Intending to present realistic environments, VR applications are including text that we are surrounded by every day. However, text can only add value to the virtual environment if it is designed and created in such a way that users can comfortably read it. With the aim to explore what values for text parameters users find comfortable while reading in virtual reality, a study was conducted allowing participants to manipulate text parameters such as font size, distance, and contrast. Therefore two different standalone virtual reality devices were used, Oculus Go and Quest, together with three different text samples: Short (2 words), medium (21 words), and long (51 words). Participants had the task of setting text parameters to the best and worst possible value. Additionally, participants were asked to rate their experience of reading in virtual reality. Results report mean values for angular size (the combination of distance and font size) and color contrast depending on the different device used as well as the varying text length, for both tasks. Significant differences were found for values of angular size, depending on the length of the displayed text. However, different device types had no significant influence on text parameters but on the experiences reported using the self-assessment manikin (SAM) scale.
