1、装饰图片影响多媒体学习的眼动研究AbstractWith the increasing popularity of multimedia learning,the impact of decorative images on learners attention and perception has become a research focus.This paper conducted an eye-tracking study on the effect of decixation time in each ROI for both the decorative image and non-decorative image groups.Table 1.Descriptive statistics of fixation measuresROI Group Mean Fixation Duration(ms)Standard Deviation(ms)Mean Fixation Count Standard Deviation Total Fixatio。

2、orative images on multimedia learning,aiming to explore the relationship between learners gaze behavior and multimedia materials.The study recruited 40 college students to participate in the experiment,the participants were assigned to a e then compared these measures between the two groups using independent samples t-tests.ResultsDescriptive statistics of fixation measuresTable 1 displays the mean and standard deviation of the fixation duration,fixation count,and total f。

3、decorative image group and a non-decorative image group.The results showed that decorative images can attract learners attention and have a significant influence on learners perception and comprehension of the material.Our findings highliount and the total fixation time in regions of interest(ROIs)within the multimedia presentation.In this study,we defined ROIs as areas where there were significant differences between the decorative image and non-decorative image groups.W。

4、ght the importance of carefully selecting and designing decorative images in multimedia learning.Keywords:multimedia learning,decorative images,eye-tracking,perception,attentionIntroductionMultimedia learning has attracted more and more alaced at the bottom of the monitor,about 60 cm away from the participants eyes.The experimenters completed a five-point calibration procedure to ensure accurate eye-tracking data collection.Data analysisWe analyzed fixation duration and c。

5、ttention with the development of education technology.It is widely used in various subjects and fields such as language learning,math,and physics education,and has shown great potential in improving learning outcomes(Mayer,2014).Multimedits received a brief introduction to the eye-tracking system and gave informed consent before the experiment.They were then seated in a quiet room and instructed to watch the multimedia presentations carefully.The eye-tracking device was p。

6、a learning combines different media,such as images,videos,and text,to present information,which can greatly enhance the learning experience and improve motivation and engagement(Fletcher&Tobias,2005).However,the impact of decorative imageresentation.We used a Tobii X3-120 eye-tracking device,which has a 120-Hz sampling rate with a spatial accuracy of 0.5 degrees of visual angle.We used Tobii Pro Lab software to collect and analyze eye-tracking data.ProcedureThe participan。

7、s on learners attention and perception in multimedia learning has been a controversial issue.Decorative images are designed to enhance the aesthetics and attractiveness of the materials without carrying explicit meaning or information(Maythe other half were without any decorative images.Each presentation consisted of 30 slides on average and lasted for about 15 min.Eye-tracking device and softwareAn eye-tracking system was used to record learners eye movement during the p。

8、er,2009).These images can be appealing to learners,but some researchers worry that they may distract learners attention from the critical information in the material(Mayer&Moreno,2003).For example,decorative images may lead learners to spncluding text,graphics,and images.The presentations were based on a textbook chapter focused on American history.Half of the multimedia presentations were embedded with decorative images to highlight the aesthetic and visual appeal,while 。

9、end more time on looking at them while ignoring the text or essential graphics,hence affecting their comprehension of the content.To investigate the impact of decorative images on learners eye movement and perception,we conducted an eye-ts were randomly assigned to two groups:a decorative image group(20 participants)and a non-decorative image group(20 participants).MaterialsThe materials consisted of 12 multimedia presentations designed with the software Adobe Captivate,i。

10、racking study.Eye-tracking technology provides a non-invasive and straightforward approach to detecting learners eye movement,such as pupil dilation and fixation,so as to investigate their attention and cognitive processing in multimedia learning environments(Chen&Chao,2017).MethodParticipantsForty college students were recruited from a public university in the United States.They were all native English speakers and had normal or corrected-to-normal vision.The participant。
