Method for providing haptic feedback to an operator of a touch-sensitive display device

A method for providing haptic feedback to an operator of a touch-sensitive display device, comprising the following steps:

• providing an operator interface, to be represented in the display device, in the form of image data, the operator interface including at least one button, assigned to a function to be controlled, graphically displayed in the operator interface and graphically delimited from the rest of the operator interface;
• analyzing the image data with regard to a presence and a position of shapes for representing a button;
• determining an intended display region of a shape, which is to be represented and is identified as a button, in the touch-sensitive display device;
• representing the image data of the operator interface in the touch-sensitive display device;
• and
• outputting haptic feedback in response to detection of contact with the touch-sensitive display device in a region of a surface of the touch-sensitive display device, the region being a region which is assigned to a display region of the shape identified as the button.

A system, comprising:

• a display device having a touch-sensitive surface;
• a device for generating haptic feedback;
• and
• a device for providing haptic feedback, via the device for generating haptic feedback, to an operator of the touch-sensitive display device, the device for providing haptic feedback being configured to:
• provide an operator interface, to be represented in the display device, in the form of image data, the operator interface including at least one button, assigned to a function to be controlled, graphically displayed in the operator interface and graphically delimited from the rest of the operator interface;
• analyzing the image data with regard to a presence and a position of shapes for representing a button;
• determine an intended display region of a shape, which is to be represented and is identified as a button, in the touch-sensitive display device;
• represent the image data of the operator interface in the touch-sensitive display device;
• and
• outputting the haptic feedback, via the device for generating haptic feedback, in response to detection of contact with the touch-sensitive display device in a region of a surface of the touch-sensitive display device, the region being a region which is assigned to a display region of the shape identified as the button.

A non-transitory computer-readable medium on which is stored a computer program for providing haptic feedback to an operator of a touch-sensitive display device, the computer program, when executed on a computer, causing the computer to perform the following steps:

• providing an operator interface, to be represented in the display device, in the form of image data, the operator interface including at least one button, assigned to a function to be controlled, graphically displayed in the operator interface and graphically delimited from the rest of the operator interface;
• analyzing the image data with regard to a presence and a position of shapes for representing a button;
• determining an intended display region of a shape, which is to be represented and is identified as a button, in the touch-sensitive display device;
• representing the image data of the operator interface in the touch-sensitive display device;
• and
• outputting haptic feedback in response to detection of contact with the touch-sensitive display device in a region of a surface of the touch-sensitive display device, the region being a region which is assigned to a display region of the shape identified as the button.
