Study Of Smart Phone Interaction Technology For User Motion States

Nowadays,smart phones have become one of the essential tools in daily life and work.And the popularity of the network has accelerated the popularity of smart phones,enabling users to use mobile phones anytime,anywhere.There are different user motion states in the process of using smart phone,such as sitting,standing,walking,and running.The performance differences are different in those user motion states.And compared with sitting,and standing,there are certain security problems and interaction problems in the running states.First of all,the different user motion states were divided into static(sitting,standing)and dynamic(running),and the performance differences of interaction technology under different motion states were investigated through the target selection tasks in daily life.The experimental results shown no significant main effect on the operation time for the user motion states,but the operation time of walking was longer than that of sitting and standing;there was a significant main effect on the error rate for the user motion states,and the error rate of walking was higher than that of sitting and standing.There was no significant difference between sitting and standing.On the basis of the above experimental results,it lays the foundation for the smart phone interaction technology under different motion states.Then,the interaction techniques for different motion states were proposed and the interaction performances were investigated.In the static state,two kinds of symbol switching techniques based on the front and back input of smart phone were designed for the text input task.The experimental results shown that the operation time of the double click on the back screen technique and the slide on the back screen technique were shorter than the traditional technique to complete the experiment task;the error rate of the slide on the back screen technique was the lowest.In the dynamic state,three kinds of target selection techniques were designed to solve the high error rate problem of target selection task.The experimental results shown that the performance of implicitly expanding technique was the best,and the performance of attract target technique was the worst.Finally,the specific application scenarios of smart phone interaction techniques in different motion states were proposed,and interactive suggestions were proposed for smart phone interaction techniques in different motion states.
