Virtual Globe technology has become a cutting-edge technology of geographic information industry in recent years. In view of the touch operations of mobile terminals and the interactive requirement in Virtual Globe, we design a set of finger-screen interactive control mechanism, which consists of a series of multi-touch gestures such as tap, slide, pinch, swipe, double click and so on, to handle the multi-scale interactive browse of 3D Virtual Globe in mobile terminals. Pixel threshold and time threshold are introduced into error control, which solves the problem of unstable disturbances and finite precision while operating the touch-screen interface. To demonstrate the feasibility and effectiveness of this mechanism, experiments were carried out on the platform of Android. The results showed that the shaking screen phenomenon and the error responses were eliminated. It achieves highly effective seamless browse of 3D Virtual Globe in mobile terminals.
