Problems solved by technology

[0003] In the case of gesture-based applications, it is disadvantageous that for several operating functions there must also be several different gestures, which must first be learned by the user
Also for some procedures a bimanual position is required which is not always possible in an interventional setting
In some processes, such as wiping gestures that require repeated execution (such as erasing 100 pages), gesture operations are also unreasonable

Embodiment Construction

[0044] A medical device with a receiver for speech or gesture detection can be used. The receiver can consist of a microphone array and an additional camera. The camera's image can also be used to point the microphone lobe at the user. Next, while the microphone lobe and / or camera remain pointed at one user, say X, the user focuses on speaking. In other words, noise from other users such as X+1 or other users in the camera image is suppressed or ignored when capturing contactless user inputs such as speech or gestures.

[0045] A system or device distinguishes three distinct states or modes of operation, which are in figure 2 Marked by Z0, Z1 and Z2 in:

[0046] Z0: "Free-running": no user eg speaker has focus, all noise is picked up (initial step).

[0047] Z1: The lobes of the microphone array are aimed at a specific user, which means that other ambient noise is suppressed, but the user is not focused, that is, there is no camera-assisted tracking.

[0048] Z2: The lob...

Abstract

The invention relates to a method to operate a device in a sterile environment and a device suitable for a sterile environment. The device is controlled by a receiving device for acquiring contact-free user input, wherein the user input is executed by different users (X, X+1). The method includes the following steps: a) connecting a first operation mode (Z1) after any of the contact-free user input of a first user or a second user is acquired; b) switching from the first operation mode to a second operation mode (Z2) after the preset contact-free user input is acquired, wherein the preset contact-free user input during the switching from the first operation mode to the second operation mode is only the contact-free user input executed in the first operation mode. Other operation modes (Z0) are activated after a non-activated stage of the user input is identified and / or other preset contact-free user input of the user of the preset user input executed in b) is acquired.

Description

technical field [0001] The invention relates to a method for operating a device in a sterile environment and to a device suitable for use in a sterile environment. Background technique [0002] It often happens in interventional medicine that doctors want to call up information from patient files and archived pictures during surgery. Such an action is only possible in the sterile OP region with operating elements, which are covered beforehand with a troublesome film. This procedure is time consuming, which requires the patient to be under anesthesia for longer periods of time, and presents a higher risk of transferring bacteria from the touched area. It is possible in such a sterile environment to use instruments which are controllable without contact, preferably by means of gestures or speech. [0003] In the case of gesture-based applications, it is disadvantageous that for several operating functions there must also be several different gestures, which must first be lea...
