An Eye Movement Study On The Effect Of Mobile 3D Touch Display Interface On User’s Search Efficiency

With the development of economy and technology,smart phones gradually occupy the mobile communications market.According to the latest statistical report on the communications industry issued by the Ministry of Industrialization and Information,China’s mobile phone penetration rate in 2017 reached 102.5 units per 100 employees(Ministry of Industry and Information Technology,2017).The development of large-screen smartphones has resulted in more and more information being presented,further increasing the user’s touch-clicking operations during the human-computer interaction.The 3D Touch innovative technology has played a significant role in simplifying the operation of the mobile phone.However,the developers of the system and the developers of the application are still in the trial-and-error period.The effect of the technology and the interface display mode remains to be verified.This study mainly through two experiments to explore the different information arrangement of mobile 3D Touch display interface and background information on user search efficiency.Experiment 1 is a single factor(information prompting method:sequential,quadrangular,symmetry axis)experiment design,using the SMI eye tracker to record the target search eyes of 47 college students in mobile phone interface images with different information prompt methods.Dynamic trajectory.The results show that the sequential search efficiency is the highest,followed by the square,and the symmetric axis search efficiency is the lowest.Experiment 2 is an experiment design with 3(information prompting mode:sequential,quadrangular,symmetry axis type)× 2(information background transparency:high and low).Using the same method as experiment one,we further explored the eye movement trajectory in the mobile interface with different information prompting modes and different transparency information prompting backgrounds.The results showed that:(1)The subjects searched efficiently in the mobile interface with sequential information prompting mode;(2)The search efficiency was high in the mobile interface with low transparency of information prompting background.Based on the results of Experiment 1 and Experiment 2,we found that:The characteristics of different mobile phone 3D Touch information prompt interface will affect the individual’s search efficiency,and the individual will search more efficiently in the mobile interface with sequential information-prompt mode and low transparency information prompt background.
