Patent number: 9424761Abstract: Simulation systems and methods may enable medical training. A manufacturing unit may receive data from a configuration unit indicating identification and manufacturing parameters for an anatomy model. A data processing unit may receive data from the configuration unit identifying the anatomy model, and data from a calibration unit indicating a position and/or orientation of a position and orientation sensor relative to the anatomy model. The data processing unit may also receive data from the position and orientation sensor indicating a position and/or orientation of the anatomy model. The data processing unit may generate a virtual image using the data from the position and orientation sensor, the data from the calibration unit, and the data from the configuration unit. The data processing unit may render the virtual image to a display.Type: GrantFiled: July 16, 2015Date of Patent: August 23, 2016Assignee: VIRTAMED AGInventors: Stefan Tuchschmid, Carolyn O'Brien, Daniel Bachofen, Matthias Harders, Jonas Spillmann

Patent number: 9330502Abstract: Mixed reality simulation in general, and more specifically to mixed reality simulation devices and systems for training purposes, for example in the medical field, may be provided. For example, a mixed reality simulation method for rendering on a display a mixed reality scenario of a virtual environment adapted to a physical environment, may comprise acquiring, with a sensor, a position of a physical environment object; identifying a mismatch between a physical environment surface and a virtual environment surface, the mismatch depending on the physical environment object position and a mixed reality scenario parameter; and computing a mapping displacement for a virtual environment surface based on the identified mismatch.Type: GrantFiled: September 11, 2013Date of Patent: May 3, 2016Assignees: EIDGENOESSISCHE TECHNISCHE HOCHSCHULE ZURICH (ETH ZURICH), VIRTAMED AGInventors: Stefan Tuchschmid, Jonas Spillmann, Matthias Harders
