Research And Implementation Of Interaction Technique For Displays Based On Movable Touch-Screen

With the development of touch-screen technology, more and more touch-screen devices in our daily life, The screen displays information to people while providing interactive features.Many public places such as cultural centers, shopping malls, railway stations use touch-screen to display information, these touch-screens are nearly not equipped with traditional interaction devices such as mouse and keyboard,they interact information by finger touch. Many semi-public or public places such as conference rooms and families use the touch-screen for information exchange, although this natural operate mode makes the interaction more intuitive,interaction distance is limitted. Therefore, to adapt to different environments, a new interaction techniques to provide more convenient for people must be researched.Based on the research of primary interaction techniques for touch-screen, the thesis present Move&Touch a novel interaction technique for displays based on movable touch-screen.This technique use the phone to establish a connection with the display by bluetooth,people can use their finger to slide or click on the touch-screen to achieve the remote control of the display, including PointerLocating, ObjectSelecting and SlideScroll. It improves the efficiency of interaction while bringing people a new interactive experience.The author research several primary problems of Move&Touch in the thesis: firstly, research the events listening and processing, analyse the type of users'operations and intents and the mapping relationship between them, and on this basis, design a structure of Move&Touch standard event stream, use the coordinate mapping algorithm to process the pointer location of display; secondly, research the bluetooth technology, demonstrate the feasibility and advantages of using bluetooth as the communication network of Move&Touch, analyse the bluetooth communication process and service protocol and security mode of Move&Touch; thirdly, implement the prototype system on WindowsCE6.0, then evaluate the performance through a multitaping test based on ISO9241-9[38] standard and finish a questionnaire of the user acceptance of system based on IBM PSSUQ , the results show that the usability of Move&Touch is close to notebook touchpad.Lastly,make a summary and outlook on the function and application of Move&Touch.
