Effective zooming method by gesture drawing on the touch screen for mobile web browser = 모바일 웹 브라우저를 위한 제스쳐 인식 기반 터치 줌 방법

다국어 초록 (Multilingual Abstract)

Mobile devices are being widely used to access Internet contents. However, it is inconvenient to browse large web pages on mobile devices with small screen. In this work, we propose an effective zooming method which provides the user a simple way to zoom in and out the web pages. By drawing specific shapes on a touch-screen device, the user can intuitively enlarge the desired contents or have an overview of the whole web page depending on the shape drawn.
To execute the procedure accurately, we propose a simple method to classify the shape drawn into two predetermined patterns and also an algorithm to scroll the browser screen in order to precisely fit the content selected by the user on the screen.
