Leading format is one of the most useful methods of presenting text on the Video Display Terminal (VDT).In present study,the effects of display speeds,window sizes and moving steps in leading format on Chinese text reading comprehension.The experiment was a mixed design of 3 (moving steps,within subject variables)×3 (display speeds,within subject variables)×2(window sizes,between subject variables),and 18 participants took part in the experiment.Results showed that each of the three variables all affected reading comprehension;and the most efficient reading comprehension condition was around 200—400 characters per minute on the display speed and 1~3 characters per step on the moving steps.The causes of these findings on the bases of eye movement theories on Chinese text were discussed.

引导式显示是在视觉显示终端 (VDT)上呈现动态文本的主要方式之一。本研究考察了显示窗口大小、跳动步幅、显示速度等因素对引导式中文文本的阅读工效的影响。实验中采用了 3(跳动步幅 ,被试内变量 )× 3(显示速度 ,被试内变量 )× 2 (显示窗口大小 ,被试间变量 )的混合设计 ,共有 18个被试参加了实验。结果发现 :( 1)跳动步幅、显示速度和窗口大小均影响中文文本的阅读工效 ;( 2 )达到最佳阅读工效的实验条件在速度和步幅上分别集中于 2 0 0~ 40 0字 /分和 1~ 3字 /步。最后本文结合中文阅读的相关眼动研究 ,对这些结果的成因进行了简要的探讨

In order to offer some ergonomic parameters for Chinese user interface designing, a series of experiments were developed within the framework of human factors to study Chinese script readability in single line VDT windows. The present study investigated the effects of 5 display factors (i.e. display window size (DWS), display rate (DR), step length (SL), word splitting (WS), character space (CS), and display rate controlling methods) on reading efficiency in three different display formats (jumping leading...

In order to offer some ergonomic parameters for Chinese user interface designing, a series of experiments were developed within the framework of human factors to study Chinese script readability in single line VDT windows. The present study investigated the effects of 5 display factors (i.e. display window size (DWS), display rate (DR), step length (SL), word splitting (WS), character space (CS), and display rate controlling methods) on reading efficiency in three different display formats (jumping leading format (JLF), gliding leading format (GLF), and rapid serial visual display (RSVP)). The results showed that DR, DWS, and SL (only if in JLF) had the greatest influence on reading performance. Word step, however, did not enhance reading performance. The increase of character space led to worse performance. In addition, it was found that JLF worked better than RSVP, and was more readily accepted by the subjects. An investigation into the effects of display rate controlling methods revealed that the subjects performed worse in self paced reading than in computer controlled reading, and that the preferred display rate was slower than the optimal display rate. The present findings suggested that the cognitive processing of Chinese dynamic script reading was more complex than Chinese static script reading, and therefore deserved further investigation.

从认知工效学的角度出发,本文对单行窗口显示条件下的汉语文本阅读进行了一系列研究.研究涉及的显示方式包括跳动引导式、平滑滚动引导式和快速系列视觉呈现式(RSVP)等3种,显示参数包括窗口大小、显示速度、跳动步幅、词切分、字间距以及显示速度控制方式等.研究结果表明在单行窗口条件下,影响阅读绩效的主要参数是显示速度、窗口大小、跳动步幅(仅在跳动引导式中)和字间距.与英文不同,本文发现汉语阅读时词步幅未能使阅读绩效提高,且字间距的增大会引起跳动引导式阅读绩效的下降.在呈现方式上,平滑滚动引导式在阅读绩效上高于RSVP,且易于被人接受.在控制方式上,自控速度方式的阅读效率低于机控速度方式,但被试者偏爱的显示速度略低于阅读效率最高的显示速度.汉语动态文本的认知加工比静态文本更为复杂,所以应对汉语文本阅读的特征和规律深入研究.研究所得各参数对于相关产品的界面设计具有参照价值.

Every feature sub- space is independent of another, and can transform the two comnonly- used performance measures- recalling rate and precision rate to correct classification rate and incorrect classification rate at the same time. Also it can review the dimension of the feature sub- space and boundary value influence...

In this paper a dynamic text classifier based on VSM is designed,it provides different classes with different feature sub- spaces. Every feature sub- space is independent of another, and can transform the two comnonly- used performance measures- recalling rate and precision rate to correct classification rate and incorrect classification rate at the same time. Also it can review the dimension of the feature sub- space and boundary value influence on these performance measures. The dynamic text classifier can categorize the user input stream of Chinese text dynamically.

设计了一种基于VSM模型的动态文本分类器,它能针对文本的不同类别建立不同的特征子空间,各特征子空间之间相互独立,同时能将文本分类中常用的2个评估指标召回率和精确率转化为正确分类率和错分率;考察了特征子空间的维数和判定界值对这2个指标的影响.该动态文本分类器能对用户输入的文本流进行动态分类.
