Enhanced virtual suction tool

摘要

A touch-based computer graphics user interface enhances a stylus pen with virtual suction to create a virtual vacuum or suction tool. The virtual tool may simulate a physical world suction tool and/or provide capabilities not available in the real world. The virtual suction tool allows the user to feel as if he or she has transcended the boundary between the virtual world and the real world by physically holding in his or her hand an object that is able to interact with and virtually attract and contain items (e.g., objects with characteristics and behaviors) removed from or expellable into the virtual world. The resulting highly intuitive user interface provides fun and exciting video game play and has other applications as well.

主权项

1. A method of presenting a user interface comprising:
displaying, by a touch screen and using a processor, an object in a virtual space; using the processor, changing at least one of the orientation and size of the displayed object; receiving a touch input at a first point on the touch screen; in response to the received touch input at the first point, using the processor to control the display to appear as if the displayed object were being absorbed by the touch input at the first point; using the processor, sensing a further touch input at a second point on the touch screen; and using the processor to control the touch screen to make it appear as if the further touch input at the second point were expelling and placing the object into the virtual space to restore at least one of said orientation and size.
