SYSTEMS AND METHODS OF MULTI-TOUCH INTERACTION WITH VIRTUAL OBJECTS

摘要

A method is provided for enabling user interaction with virtual objects in a virtual world using a touchscreen device. A touch input within or across a region of the display is detected from the touchscreen device. After determining that the touch input exceeds a predetermined threshold, and further determining whether the touch input is of a single touch or multi-touch type based on a number of contacts detected in the touch input, a multi-touch type input is interpreted as a multi-touch attract or repel command with respect to a virtual object displayed on the display. The virtual object is then visibly moved or changed on the display in response.
