Abstract

A method for controlling a touch screen including a display adapted to display at least one graphical interface element with a first graphical resolution, and a touch surface including a plurality of detection areas forming a detection grid whose touch resolution is lower than the first resolution. The method being such that it includes steps of determining a display position of a graphical interface element on the display such that the number of detection areas covered by the graphical interface element is minimal, displaying the graphical interface element at the determined position and triggering a function associated with the graphical interface element when a contact is detected in a detection area covered by the graphical interface element. Other aspects relate to a device for performing such a method and a touch screen including the device.

Claims (17)

1 . A method for controlling a touch screen comprising a display adapted to display a graphical interface element with a first graphical resolution, and a touch surface comprising a plurality of detection areas forming a detection grid whose touch resolution is lower than the first graphical resolution of the graphical interface element, the method comprising:

obtaining a first display position of the graphical interface element with the first graphical resolution on the display,

determining a second display position of the graphical interface element with the first graphical resolution on the display such that a number of the plurality of detection areas covered by the graphical interface element is minimal,

displaying the graphical interface element at the second determined display position,

triggering a function associated with the graphical interface element when a contact is detected in a detection area covered by the graphical interface element in the second determined display position.

2 . The method as claimed in claim 1 , wherein the step of determining a position of the graphical interface element comprises determining a display position of the graphical interface element such that at least one border of the graphical interface element is aligned with a border of the detection area.

3 . The method as claimed in claim 1 , wherein the step of determining the position of the graphical interface element comprises determining a display position of the graphical interface element such that at least two consecutive edges of the graphical interface element are respectively aligned with at least two borders of the detection area.

4 . The method as claimed in claim 1 further comprising:

determining at least one dimension of the graphical interface element such that the interface element covers an integer number of detection areas according to the determined at least one dimension, and

resizing the graphical interface element according to the determined at least one dimension of the graphical interface element.

5 . A non-transitory information medium comprising computer program instructions configured to perform the steps of a method for controlling a touch screen as claimed in claim 1 when the instructions are executed by a processor.

6 . A device for controlling a touch screen comprising a display adapted to display a graphical interface element with a first graphical resolution, and a touch surface comprising a plurality of detection areas forming a detection grid whose resolution is lower than the first graphical resolution of the graphical interface element, the device further comprising a processor coupled to a memory that stores computer program instructions configured to perform:

obtaining a first display position of the graphical interface element with the first graphical resolution on the display,

determining a second display position of the graphical interface element on the display such that a number of the plurality of detection areas covered by the graphical interface element is minimal,

displaying the graphical interface element at the second determined display position, and

triggering a function associated with the graphical interface element when a contact is detected in a detection area covered by the graphical interface element in the second determined display position.

7 . A touch screen comprising the control device as claimed in claim 6 .
