Study And Design Of Personal Portable Computer Touch Screen Input Mode

In response to the needs of entertainment and work, the major electronic manufacturers released large size of tablet products include series products of Microsoft Surface, Google PixelC, iPad Pro.Currently some laptops and desktops and is equipped with touch screen,but most products still use the mouse cursor point operation way.Forced the combination of touch screen and point operation, which brought user confusion. In addition, the interaction of the most portable computer applications are based on the keyboard and mouse, which bring poor touch screen interactino experience.This study analyzes the personal portable computer characteristics of use situation, habits, operating space.Summarized five aspects factors including the cognitive load,usage scenarios, physiological characteristics, input details, interface design, that influence the touch screen input user experience. Situational response of user interface design model is put forward.Personal portable computer touch screen input including Chinese handwriting input, signal input and control input.Twelve subjects is studied through experiments under three kinds of use gestures,five kinds of input box size,five kinds of input box location of the touch screen handwriting input. Verify the influence of the usage scenarios for personal portable computer touch screen input performance and subjective evaluation.In addition, this topic through user-defined method, combined with the result of usability testing, extracted a set of gestures library for personal laptops.According to the gesture operation mode, gestures of personal portable computers can be divided into three categories including basic gesture,symbolic gestures,combined gestures.Summarized the characteristics of all kinds of gestures and design suggestions for personal portable computer gesture.Based on the rapid gesture library,designers and developers can design the gesture interaction of their products quickly and reasonably.In addition, in view of the function of unfavorable use gestures in the experiment, quick control prototype is put forward based on the tag menu for personal portable computer. Improving the input performance and user experience on the portable computer in three aspects including Chinese input, signal input and control input.
