Visual expertise is a fundamental proficiency in many vocations and many questions have risen on the topic, with studies looking at experts and novices differences’ in observation (e.g., radiologists) or at ways to help novices achieve visual expertise (e.g., through annotations). However, most of these studies focus on white-collar professions and overlook vocational ones. For example, observing is uttermost important for fashion designers who spend most of their professional time on visual tasks related to creating patterns and garments or performing alterations. Therefore, this study focuses on trying to convey a professional way to look at images by exposing apprentices to images annotated (e.g., circles) by experts and identifying if their gaze (e.g., fixation durations and gaze coverage) and verbalisations (i.e., images descriptions) are affected. The study was conducted with 38 apprentices that were exposed to sequential sets of images depicting shirts, first non-annotated (pre-test), then annotated for the experimental group and non-annotated for the control group (training 1 and training 2), and finally non-annotated (post-test). Also, in the pre and post-test and in training 2 apprentices had to verbally describe each image. Gaze was recorded with the Tobii X2–60 tracker. Results for fixation durations showed that the experimental group looked longer in the annotated part of the shirt in training 1 and in the shirt’s central part at post-test. However, the experimental group did not cover a significantly larger area of the shirt compared to control and verbalisations show no difference between the groups at post-test.

专家注释对时装设计师学徒注视模式和语言表达的影响

视觉专业知识是许多职业的基本熟练程度,并且在该主题上出现了许多问题,研究着眼于专家和新手在观察方面的差异(例如放射科医生)或帮助新手获得视觉专业知识的方法(例如,通过注释)。然而,这些研究大多侧重于白领职业,而忽视了职业职业。例如,对于将大部分专业时间花在与创建图案和服装或进行修改相关的视觉任务上的时装设计师来说,观察是极其重要的。因此,本研究的重点是通过让学徒接触专家注释的图像(例如圆圈)并识别他们的凝视(例如,注视持续时间和凝视覆盖)和语言表达(即,图像描述)受到影响。该研究由 38 名学徒进行,他们接触了描绘衬衫的连续图像集,首先是未注释(预测试),然后为实验组注释,为对照组(训练 1 和训练 2)未注释,最后没有注释(后测试)。此外,在前测和后测以及培训中,2 名学徒必须口头描述每张图像。凝视是用 Tobii X2-60 跟踪器记录的。固定持续时间的结果表明,实验组在训练 1 时在衬衫的注释部分和在后测试时在衬衫的中央部分看起来更长。然而,与对照组相比,实验组没有覆盖显着更大的衬衫区域,并且在测试后两组之间的语言表达没有差异。该研究由 38 名学徒进行,他们接触了描绘衬衫的连续图像集,首先是未注释(预测试),然后为实验组注释,为对照组(训练 1 和训练 2)未注释,最后没有注释(后测试)。此外,在前测和后测以及培训中,2 名学徒必须口头描述每张图像。凝视是用 Tobii X2-60 跟踪器记录的。固定持续时间的结果表明,实验组在训练 1 时在衬衫的注释部分和在后测试时在衬衫的中央部分看起来更长。然而,与对照组相比,实验组没有覆盖显着更大的衬衫区域,并且在测试后两组之间的语言表达没有差异。该研究由 38 名学徒进行,他们接触了描绘衬衫的连续图像集,首先是未注释(预测试),然后为实验组注释,为对照组(训练 1 和训练 2)未注释,最后没有注释(后测试)。此外,在前测和后测以及培训中,2 名学徒必须口头描述每张图像。凝视是用 Tobii X2-60 跟踪器记录的。固定持续时间的结果表明,实验组在训练 1 时在衬衫的注释部分和在后测试时在衬衫的中央部分看起来更长。然而,与对照组相比,实验组没有覆盖显着更大的衬衫区域,并且在测试后两组之间的语言表达没有差异。
