Embodiment Construction

[0081] figure 1 A flowchart of a method for associating a pick gesture with a first tool 601 , 602 , 603 is shown. exist figure 1 The first step of the method shown in is to first determine the first position 311.1 of the thumb 301 of the hand 300 of the person 701 and the first position 311.1 of the index finger 302 of the hand 300 of the person 701 at the first time point DET-1 by means of the first position detector 240. One position 312.1. In the illustrated exemplary embodiment, a first position marker 321 is arranged on the thumb 301 and a second position marker 322 is arranged on the index finger 302 . The first position mark 321 and the second position mark 322 are respectively spherical objects having a color different from that of the hand 300 , for example, white.

[0082] In the illustrated embodiment, the first position detector 240 is a system of a plurality of sub-position detectors 240.1,...,240.4, wherein each of the sub-position detectors 240.1,...,240.4 i...

Abstract

The invention relates to a method for associating a first tool with a picking gesture, comprising first determining, by means of a first position detector, a first position of a thumb of a person's hand and a second position of an index finger of a hand at a first point in time A position; by means of the calculation unit based on the first position of the thumb and the first position of the forefinger, first calculating the first distance between the thumb and the forefinger at the first point in time; secondly determining the second point in time by means of the first position detector The second position of the thumb and the second position of the index finger, wherein the second time point is in time after the first time point; by means of the calculation unit based on the second position of the thumb and the second position of the index finger, the second calculation of the second A second distance between the thumb and forefinger at the point in time; the first recognition of the picking gesture based on the first distance and the second distance by the computing unit; selecting the first tool from the tool set based on the tool position of the first tool by the computing unit; The computing unit associates the first tool with the pick gesture.

Description

technical field [0001] The invention relates to a method and an associating system for associating a first tool (601, 602, 603) with a picking gesture. Background technique [0002] In many technical fields, especially in medical technology, the user is not on a real object (such as a patient or a technical device), but in virtual reality (English term "Virtual Reality", abbreviated "VR"), in a mixed The training and training of the workflow is performed on a training object in reality (“Mixed Reality” in English term, abbreviated as “MR”) or on a training object in augmented reality (“Augmented Reality” in English term, abbreviated as “AR”). Such training or training can be monitored by sensors and analyzed automatically, so that, for example, the success of the training can be assessed automatically or the training can be adapted to the requirements and abilities of the user. [0003] In order to enable automated analysis, or also to display training or training in virtua...
