On The Principles Of General User Interface Design In Touch Screen

Through the understand of User Interface Design and touch screen, the essay found the problem of User Interface Design in touch screen and then felt deeply the importance of the usability of user interface in touch screen and the repetitive investment in design. Thereby the essay found it is very essential to offer a series of principles of general user interface design in touch screen.In the first chapter, the essay introduced the research background,objective,significance and method.In the second chapter, the essay introduced the basic concepts of touch screen and user interface design including the beginning of touch screen,it's development process,the technology of touch screen,usable range of touch screen and the notion of user interface design on all sides.In the third chapter, the eassy listed and referred to some theories of the user interface design,usability,Human Factors Engineering as well as the user research method and so on.In the fourth chapter, though analysing different kinds of design cases and being enlightened by some theories already in existence. The essay assumed a series of principles of general user interface design in touch screen in order to make it fit for different kinds of touch screen interface design.In the fifth chapter, the essay demonstrated the hypothesis above by designing the project of"The touch screen of ventilation system in factory workshop". The process of demonstration including building the research model,requirement investigation,setting the usability index and so on. Then compared the design indexes of this project which came from the analysis above with the Hypothesis—principles of general user interface design in touch screen. Look over the difference between them. Next, worked out the prototype design and gave it to the user to do the usability testing. Though the usability testing, we can find out the drawback in the previous design and improve it. Then, gave it to the user to do the usability testing once again. After doing this circular design process, the essay confirmed the hypothesis—principles of general user interface design in touch screen is correct and proper basically and also supplemented the hypothesis to make it become a perfect and scientific principles.In the sixth chapter, according to the research and analysis result, the essay embodied and abridged the research conclusion as well as listed it. At last, the essay gave the aspects need to improve in the research and draw the future research direction.
