Background: Besides the current challenge, the perceived difficulty level of a learning task depends on the student's previous knowledge and skills. When a learning task is recurrently perceived as easy (or hard), it may cause poor learning results. Gamer data such as errors, attempts, or time to finish a challenge are widely used to estimate the perceived difficulty level. In other contexts, pupillometry is widely used to measure the cognitive load (mental effort); hence, this may describe the perceived task difficulty.
Objective: Objective: This study aimed to assess the use of pupillary data as a cognitive load measure for describing the difficulty levels in a video game. Also, it proposes an image filter to better estimate the baseline pupil size and to reduce the screen luminescence effect. Methods: We conducted an experiment that compares the baseline estimated from our filter against that estimated from common approaches. Different pupil features were used to classify the difficulty of a dataset containing information from students playing a video game for practicing math fractions. Results: Results: Results showed that the proposed filter allows to better estimate a baseline, Mauchly’s Test of Sphericity indicated that the assumption of sphericity had been violated, χ2(14) =0.045389, p = .001; and therefore, a Greenhouse-Geisser correction was used, ε = 0.47, there was a significant difference against Mean Pupil Diameter Change (MPDC) estimated from different baseline images with the scramble filter, F(2.35) = 30.965, p < .001. Moreover, according to the Wilcoxon signed-rank test, pupillary features that better describe the difficulty level were MPDC (Z = -2.15, p <0.05) and Peak Dilation (Z = -3.58, p<0.00); a random forest classifier for easy- and hard-level of difficult showed an accuracy of 75% when the gamer data is used, but the accuracy increases to 87.5 % by including pupillary measurements. Conclusions: The screen luminescent effect on pupil size was reduced with a scrambled filter on the background video game image. Finally, pupillary data can improve the classifier accuracy of the perceived difficulty of gamers in educational video games.
(Philadelphia/Toronto, July 2, 2023) We are excited to announce that JMIR Serious Games (JSG) has received an impact factor of 3.53 according to the newly released Journal Citation Reports (Web of Science Group, 2023).
In addition to JSG, we are also proud to announce the impact factors for other JMIR journals. The Journal of Medical Internet Research(JMIR) now has an 极光加速官网, JMIR mHealth and uHealth (JMU) now has an impact factor of 4.31, JMIR Medical Informatics (JMI) received an impact factor of 2.58 and, with an 极光vp下载:2021-5-20 · 极光IP加速器是一款独特的动态IP静态IP伋理切换软件,独享专线带宽。拥有200+中国大陆不同地区的伋理服务器,让你远离网络延迟! ... 极光vp 下载 极光vp 安卓下载 极光vp 安卓破解版 极光vp n 永久免费 vp社区 电子烟 极光单词返现是真的吗 极光 ..., JMIR Mental Health (JMH) has been recognized for the important work that has been published since the journal first launched in 2014.

While we are proud of our impact factor, we do want to stress that impact factors should not be the only metric to gauge the influence and quality of a journal. We will not support any misuse of impact factors. Although not all JMIR Publications’ journals have impact factors yet, we have the same quality expectations and processes for all our journals. All papers undergo a thorough peer-review and editing process. All applicable journals are indexed in PubMed. We encourage authors to consider other quality metrics as well, such as top author satisfaction ratings on sites such as SciRev or Google, where JMIR also has consistent 5-star ratings.
