Devices and methods of controlling manipulation of virtual objects on a multi-contact tactile screen
First Claim
1. A method for controlling a computerized device by a multi-contact touch screen, the method comprising:
- displaying first and second graphical objects on the multi-contact touch screen at first and second object positions, respectively;
associating first and second specific processing rules to the first and second graphical objects, respectively;
detecting first and second touch points on the multi-contact touch screen and defining first and second touch positions for the first and second touch points, respectively;
applying the first specific processing rule of the first graphical object as a function of a relative position between the first touch position and the first object position;
applying the second specific processing rule of the second graphical object as a function of a relative position between the second touch position and the second object position;
modifying at least one of the first graphical object or the first object position based on a result of said applying the first specific processing rule; and
modifying at least one of the second graphical object or the second object position based on a result of said applying the second specific processing rule.

Abstract
A process for controlling computerized equipment with a device including a multi-contact bidimensional sensor that acquires tactile information and a calculator that generates command signals as a function of the tactile information, including graphical objects on a screen placed under a transparent multi-contact tactile sensor, each graphical object associated with at least one specific processing rule such that the sensor delivers during each acquisition phase a plurality of tactile information, and each piece of the tactile information forms an object of a specific processing determined by its localization relative to a position of one of the graphical objects.

25. A device to control a computerized apparatus comprising:
-
memory to store first and second graphical objects and first and second specific processing rules that are associated to the first and the second graphical objects, respectively; a multi-contact touch screen to detect first and second touch points on the multi-contact touch screen and defining a first and a second touch position for the first and the second touch points, respectively; a graphic display unit to display the first and second graphical objects at a first and a second object position, respectively; and a processor configured to apply the first specific processing rule associated to the first graphical object as a function of a relative position between the first touch position and the first object position, configured to apply the second specific processing rule associated to the second graphical object as a function of a relative position between the second touch position and the second object position, configured to modify at least one of the first graphical object or the first object position based on a result of said processing said first specific processing rule, and configured to modify at least one of the second graphical object or the second object position based on a result of said processing said second specific processing rule. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A method for controlling a computerized device by a multi-contact touch screen, the method comprising:
-
displaying first and second graphical objects on the multi-contact touch screen at first and second object positions, respectively; associating first and second specific processing rules to the first and second graphical objects, respectively; detecting a touch zone including first and second touch points on the multi-contact touch screen and defining a zone position for the touch zone based on a location of both the first and second touch points; detecting a third touch point on the multi-contact touch screen and defining a touch position for the third touch point; applying the first specific processing rule of the first graphical object as a function of a relative position between the zone position and the first object position; applying the second specific processing rule of the second graphical object as a function of a relative position between the touch position and the second object position; modifying at least one of the first graphical object or the first object position based on a result of said applying the first specific processing rule; and modifying at least one of the second graphical object or the second object position based on a result of said applying the second specific processing rule.
