Force Sensing Touchscreen Gesture Of Time-Space Modeling And Recognitiong System Prototype Development

Touch gesture is the most convenient, simple and natural human-computer interaction. It has been widely used in various fields and various industries. It greatly simplifies the use of computers, even some people who never used a computer. The application of computer easily makes it more attractive. Now in the user-centered concept, the touch gestures design is particularly important. Therefore, the development and modeling of gestures makes touch screen a broader application.This paper researches the key technology of single-point touch, multi-point on surface acoustic wave screen. Analyzing gestures which include touch point P detected in space and relative time parameter T. At the same time, we add a touch -sensitive dynamic into the identify elements, form a three-dimensional coordinate system, increasing the diversity of gestures. As a result, it makes gesture more diverse and the coordinate is more suites to user’s habit. In addition, establish the model of recognition and write application with the recognition algorithm so that single point and multi point recognition in surface acoustic wave screen is implemented. Finally, developing the system to verify the accuracy and speed recognition of single point and multi point with touch strength. The system enriches the display of gesture recognition, not only in text, but also adds personalized sounds, pictures and animated demonstration.The paper proposes the definition and design based on force sensing touch screen gestures, the touch interaction to complete the formation of a unified library of gestures. Interaction designers can choose their useful gesture to sever the different application and enhance the adaptability and convenience of interactivity gestures.
