AI Technical Summary

Technical Problem

Augmented reality head-mounted displays in medical settings often obstruct the user's view of the physical anatomical body part due to superimposed 3D models, making it difficult to navigate instruments accurately.

Method used

A computer-implemented method for a semi-transparent see-through display device that renders a clear space transparently around the model, allowing the user to see the physical anatomical body part and superimposed models simultaneously, using position data from tracking systems to determine and display this clear space.

Benefits of technology

Enhances visibility of both the physical anatomical body part and superimposed models, improving navigation accuracy and reducing obstruction, thereby simplifying medical procedures.

Abstract

A computer-implemented method for providing display data to a semi-transparent see-through display device in a medical setting, comprising the steps of: providing a 2D and / or 3D model of a first object (step S1); receiving first position data of the first object (step S2); receiving second position data of a second object (step S3); capturing a free space based on the second position data (step S4); determining display data for display on a semi-transparent see-through display device based on the 2D and / or 3D model, the captured free space, the first position data, and the second position data (step S5); and providing the determined display data for display on the semi-transparent see-through display device (step S6).
