Abstract

The invention relates to a method of providing touchless manipulation of an image through a touchless input device (210), the method comprising selecting a property of a manipulation mode with the image in response to touchless user interaction along a first axis with respect to a plane of a sensing region (206, 208) of the touchless input device, and manipulating the image in response to touchless user interaction along a second axis substantially orthogonal to the first axis according to the selected property of the manipulation mode. The invention further relates to a computer program product, a computer storage medium, a display device and a medical workstation.

Claims

1. Method of providing touchless manipulation of an image through a touchless input device (210), the method comprising:

selecting a property of a manipulation mode with the image in response to touchless user interaction along a first axis with respect to a plane of a sensing region (206, 208) of the touchless input device, and

manipulating the image in response to touchless user interaction along a second axis substantially orthogonal to the first axis according to the selected property of the manipulation mode.

2. Method according to claim 1, wherein the second axis is substantially parallel to the plane.

3. Method according to claim 1, further comprising displaying the property of the manipulation mode.

4. Method according to claim 3, wherein the displayed property of the manipulation mode is proportional to a value of the property.

5. Method according to claim 1, wherein the manipulation mode is one of brightness, contrast, zoom or rotation and the property is a step size of the respective manipulation mode.

7. A computer readable storage medium (512) having recorded thereon data (514) representing instructions for performing a method according to claim 1.

8. Display device (516) for providing touchless manipulation of an image, the display device comprising a display (504), a touchless input device (210) and a processor (506) configured to perform a method according to claim 1.

9. Medical workstation (516) comprising a display (504) and a touchless input device (210) for providing touchless manipulation of an image, the touchless input device (210) comprising a processor (506) configured to perform a method according to claim 1.

6. A computer program product to be loaded by a computer arrangement, comprising instructions for providing touchless manipulation of an image through a touchless input device (210), the computer arrangement comprising a processing unit and a memory, the computer program product, after being loaded, providing said processing unit with the capability to carry out the following tasks:

selecting a property of a manipulation mode with the image in response to touchless user interaction along a first axis with respect to a plane of a sensing region (206, 208) of the touchless input device, and

manipulating the image in response to touchless user interaction along a second axis orthogonal to the first axis according to the selected property of the manipulation mode.
