Abstract

The invention relates to a gesture support device (10) for controlling and/or operating a medical device (24), wherein the gesture support device is used to make gestures which are to be detected by a gesture detection system (23) and translated into control and/or operating inputs for the medical device (24), characterized in that the gesture support device (10) comprises discrete or delimited sections (12-18) which can be recognized as such by the gesture detection system (23). It also relates to a system for controlling and/or operating a medical device (24), comprising such a gesture support device, and to a method for controlling and/or operating a medical device (24).

Claims

1. A gesture support device for controlling and/or operating a medical device, wherein the gesture support device is used to make gestures which are to be detected by a gesture detection system and translated into control and/or operating inputs for the medical device, characterized in that the gesture support device comprises discrete or delimited sections which can be recognized as such by the gesture detection system.

2. The gesture support device according to claim 1, characterized in that it is divided into discrete sections which can be recognized as such by the gesture detection system.

3. The gesture support device according to claim 1, characterized in that the sections comprise recognizable elements or structures, in particular one or more of the following:

patterns (11A, 11B, 11C);

sizes;

colors;

labels.

4. The gesture support device according to claim 1, characterized in that it consists of several parts which have to be assembled in order to form the functional gesture support device, each part comprising one or more of the discrete or delimited sections.

5. The gesture support device according to claim 4, characterized in that the parts comprise a connection system which allows them to be connected in one or more predetermined and distinguishable relative positions.

6. The gesture support device according to claim 1, characterized in that it is a foldable device which can in particular be folded along the borders between sections.

7. The gesture support device according to claim 1, characterized in that it comprises a designated sterile area and a designated non-sterile area and in particular comprises a sterile border portion or border element in between.

8. The gesture support device according to claim 1, characterized in that it comprises a designated, in particular marked or labeled, grip portion.

9. The gesture support device according to claim 1, characterized in that it comprises a control button, in particular an activating button for issuing control outputs electronically or as audio outputs.

10. The gesture support device according to claims 1, characterized in that it has a rod-like form, a cube-shaped form or a spherical form.

11. The gesture support device according to claims 1, characterized in that the medical device is an image-guided medical or surgical system, in particular a medical navigation system.

12. A system for controlling and/or operating a medical device, comprising a gesture support device according to claim 1 and a gesture detection system, and in particular:

a gesture translation system for translating detected gestures into control and/or operating inputs for the medical device; and

/or

the medical device itself.

13. A method for controlling and/or operating a medical device, wherein gestures are detected by a gesture detection system and translated into control and/or operating inputs for the medical device, and wherein the gestures are generated by means of a gesture support device which can be hand-held and/or manually manipulated and which comprises discrete or delimited sections which can be recognized as such by the gesture detection system.

14. The method according to claim 13, wherein the control and/or operating inputs are identified on the basis of one or more of the following:

the pointing direction of the gesture support device;

the rotational position or direction of the gesture support device or one or more of its sections; and

/or

the position and/or orientation of the hand on the gesture support device, in particular whether sections of the support device are covered or visible when the gesture support device is handled or gripped by a user.
