SYSTEM AND METHOD FOR CONTROLLING ZOOMING AND/OR SCROLLING

摘要

The present invention is aimed at a system and a method for instructing a computing device to perform zooming actions, for example on a picture (enlarging and reducing the size of a virtual object on a display) and scrolling actions (e.g. sliding text, images, or video across a display, vertically or horizontally) in an intuitive way, by using a controller which can detect the distance between an object (e.g. the user's finger) and a surface defined by a sensing system.

主权项

1. A system for instructing a computing device to perform zooming/scrolling actions, comprising:
a sensor system generating a measured data being indicative of a behavior of a plurality of objects in a three-dimensional space with respect to a predetermined sensing surface; and; a zoom/scroll control module associated with at least one of said sensor system and a monitoring unit being configured for receiving said measured data; wherein said zoom/scroll control module is configured for processing data received by at least one of said sensor system and said monitoring unit, and is configured for recognizing gestures and, in response to these gestures, outputting data for a computing device so as to enable the computing device to perform zooming and/or scrolling actions, wherein at least one object is hovering over the surface, said zoom/scroll control module determines the direction of the scroll/zoom according to the position of the hovering object relative to another object.
