The Optimlized Presentation Based On Dynamic Text Of Oral Reading Conditions Under The Application Of Teleprompter

Oral reading is a way of reading.It is a process of using language and text to obtain information,and it is also the starting point for the development of individual reading.By oral reading we can understand the world and explore the world.The application of dynamic texts in today's society is also very extensive,providing a large amount of information on a limited display through constantly moving textual information.According to previous studies,it has been proved that in a single-line dynamic text reading,the speed is an important indicator affecting reading efficiency.Although the main effect of window size is not significant,the interaction between window size and movement speed is significant,and both affect one-line dynamics.Reading efficiency of texts.At present,there is no definite speed for the presenter to use the teleprompter presentation speed.Under what setting,the presenter can best use the teleprompter to become a research issue.In this context,we would like to know what kind of settings are optimized for dynamic text reading?Based on this,this study combines behavior,eye movement and EVS to explore the presentation of dynamic text optimization under reading conditions.A 3(window:9 Chinese characters,15 Chinese characters,20 Chinese character)×4(display speed:25 lines/min,35 lines/min,45 lines/min,55 lines/min)multi-factor mixed experimental design was employed.The window was a between-subject factor.The display speed was a within-subject factor.33 university students(19-25 years old,M=22,SD=3)were selected as participants.The eye track of the subjects was recorded using the Hi-speed eye tracker developed by the SMI company in Germany.The professional voice recording software collected the test voice materials.using 9articles was used as experimental material(1 dynamic practice material,8 dynamic experimental materials).In the data analysis,we used three behavior indicators(oral reading accuracy,subjective evaluation,reading comprehension rate),four eye movement indicators(fixation duration average,fixation frequency,saccade amplitude average,blink frequency),and temporal EVS.The result indicated that:(1)In 9 Chinese characters,subjective evaluation and oral reading accuracy,Fixation Frequency and blink frequency were higher,Fixation Duration Average was longer,Saccade Amplitude Average,temporal EVS were lager;(2)In slow display speed(?35line/min),readingcomprehension rate,subjective evaluation,oral reading accuracy,Fixation Frequency and blink frequency were higher,Fixation Duration Average was longer,temporal EVS was lager.To sum up :(1)The 9 Chinese characters is greater benefits to oral reading.There have a larger working memory to process information and obtain a more stable eye tracking;(2)35 Lines/min is greater benefits to oral reading.There is more time for information processing and better oral reading performance;(3)We recommend that the display speed of dynamic text for oral reading is 315 words/min.
