METHOD FOR DISPLAYING AND UPDATING A VIEW OF A GRAPHICAL SCENE IN RESPONSE TO COMMANDS VIA A TOUCH-SENSITIVE DEVICE
First Claim
1. A method for displaying a current view of a graphical scene on a display by a computer device comprising a touch-sensitive device, said method comprising the following steps:
- detecting at least one pressure point on the touch-sensitive device and determining a set of coordinates for said pressure point,detecting at least one displacement of the pressure point while pressure is maintained on the touch-sensitive device and determining at least one further set of coordinates along a locus described by said displacement,calculating at least a direction attribute based on the plurality of sets of coordinates,updating the current view by moving at least part of the current view according to at least the direction attribute,continuing to update the current view by moving at least part of the current view according to at least the direction attribute until the pressure is released from the touch-sensitive device.

Abstract
A man-machine interface using a touch-sensitive device as an interface to a computer device is presented, wherein simple gestures made by a user are interpreted by the computer device as commands to be performed in respect to at least a part of a virtual environment shown on the display. Each sequence of gestures begins with an initial touch on the touch-sensitive device and may involve a number of subsequent gestures. A command thus given is applied to the part of the virtual environment on the display. The action of the command continues until the gesture is ended by the user removing contact from the touch-sensitive device, thus ending the command.
