| With the development of smart devices,smart devices are being widely used in the daily lives of young people.Educational games based on smart devices continue to gradually promote the digital development of children’s education,and the way children receive education is also innovated with the development of informatization.The man-machine interface of the next generation of children’s educational games will not only be limited to the traditional keyboard and mouse interaction methods,but will tend to multi-channel interaction methods such as vision,touch and hearing.Among them,the application of eye-control interaction in educational games undoubtedly has forward-looking research value.Based on children’s educational games,this article first analyzes children’s cognitive psychological characteristics and educational games,and obtains relevant theoretical support for this special group of school-age children,and combines the specific characteristics,implementation methods,and implementation methods of eye control and touch control.Interactive means,developed a children’s educational game for experiment.Secondly,from the perspectives of behavioral performance and subjective evaluation,we explore the differences of eye control and touch games on children’s learning under different time pressure conditions,and test the effect of eye control and touch on children’s education through a summative test.Finally,a comprehensive evaluation index of children’s educational game learning accessibility is formulated based on expert evaluation,which provides an effective reference for the design,improvement and evaluation of children’s educational games in the future.Through experiments,this article has obtained the following research results:(1)Based on the cognitive psychological characteristics of children and the characteristics of educational games,this article considers the eye control and touch operation interface and operation methods suitable for school-age children,and designs an eye control/touch education for children game.(2)Without time pressure and gender distinction,children can successfully complete eye-control and touch-control educational games and there is no significant difference in behavioral performance.However,in the case of gender distinction,girls are compared with boys Can get better results.At the same time,using NASA-TLX subjective evaluation method to verify that there is no significant difference between eye control and touch on children ’ s subjective cognitive load,but there are differences between the coefficients,among which there is no difference in effort level and performance level.The physical demands,mental demands and frustration of eye control are significantly less than those of touch control,but the level of time demand for eye control is higher than that of touch control.(3)Under no time pressure,the summative test using the pen and paper test found that both eye control and touch can provide a certain effect of educational communication for children.Among them,the interactive method of eye control is more effective than touch for educational communication.The effect is better at the time.(4)Under time pressure,the performance of eye control is significantly worse than that of touch,and the performance of the time pressure group is worse than that of the no time pressure group,indicating that under certain time pressure,children’s eye control has better performance than touch control.Lower effectiveness.(5)Using children’s satisfaction scale for eye control/touch educational games,it is found that eye control can bring more novelty to children than touch,and the experience and comfort level during use are better.(6)Using the De Fel method for expert evaluation,formulating and perfecting the evaluation index of educational game learning accessibility,and calculating the weight of the evaluation index through the analytic hierarchy process.Encourage children’s parents or teachers to consider educational games based on indicators,so as to avoid blind choices,and provide a basis for the development of educational games. |
