Large-screen Smart Phone Of Back Gesture Interaction Experience Design Research

The topic of this paper originates from the Lenovo IDC’s (Innovation DesignCenter) innovation project team. And it was one of the exploration of Lenovo iconicinteraction solutions prospective programs. The author was an intern in IDC fromApril2013to November2013.The rapid development of mobile Internet, the large-screen smart phones, as thepopularity of Internet hardware, has played an important role in people’s lives. Allkinds of APP, big screen, intelligent voice, etc. have been unable to attract the user’sattention. Large-screen smart phone’s innovation has become the only way to increasesales. To encourage people to accelerate the upgrade smartphones, Apple, Samsung,millet and other brands do not only optimize the performance, but also make greatinnovation in shape, function, experience to meet user’s needs. The mobile Screen ismore and more bigger, giving users a good visual experience, but to some extent, theinconvenience to the single-handed operation.The structure of the paper is as follows. Firstly, from the perspective of productinteraction systematic, elaborating the concept of large-screen smart phone on theback of interaction behavior. Based on user behavior in the innovative designapproach theoretically, using the natural behavior of the user field observation andquestionnaire survey method for studying smart phone users behavior, concluding theindex finger is the most natural behavior when doing back gesture interaction onbig-screen smart phone. Secondly, discussing the importance of context in the designof mobile devices experience, building a model based on user experience design sceneanalysis, Using this model theory analyzes the influencing factors and features oflarge-screen smart phone user experience. Summarizing the user pain points ofbig-screen smart phone interface interaction，based on this,summing up the contextand demands of back touch interaction of big-screen smart phone. Finally, exploringthe region of back touch interaction of large-screen smart phone and the impact ofdifferent context on back gesture by doing the user usability testing. Based on theabove conclusions, outputting the integrity program of application context oflarge-screen smart phone back touch interaction.The innovation of this paper: Firstly, on the basis of user behavior habit,subverting the traditional thinking innovative design. Secondly, exploring the context of the large-screen smart phone back touch interaction, and through usability testing,concluding the context has not influence in back touch gesture, so it has feasibility tocomplete different tasks with the same gesture. Lastly, in the design concept,considering the effect of the product semantics on back touch gestures. To guide usersnatural gestures performed on back touch, achieving available, easy and good userexperience.
