Research Group: Assessment and Training of Medical Expert with Objective Standards (ATMEOS)

Research Group: Assessment and Training of Medical Expert with Objective Standards (ATMEOS)

In highly dynamic and complex high-risk domains - such as surgery - systematic training in the relevant skills is the basis for safe and high-quality performance. Traditionally, assessment and training in surgery traditionally concentrated upon proficiency and acquisition of surgeons' technical skills. As the fundamental impact of non-technical skills - such as communication and coordination - is increasingly acknowledged for safe delivery of surgeries comprehensive training approaches are missing. The overall aim of the project is to investigate a novel learning environment for the assessment and training of both technical and non-technical skills of entire multidisciplinary operating room (OR) teams.

MeTaTop A Multi Sensory Table Top System for Medical Procedures

MeTaTop A Multi Sensory Table Top System for Medical Procedures

A tabletop system in medical environments can be used for interactive and collaborative analysis of patient data but also as a multimedia user interface within sterile space. For preoperative planning physicians in charge with a particular patient meet to discuss the medical case and plan further steps for therapy. For this reason, they could collaboratively view and browse through all kind of available medical imaging data with the tabletop system. Alternatively such a system could be a central interaction device for all kind of equippment within the OR requiring user input, however, can not be operated by the sterile surgeon. We believe that the projection of all kind of user and information interfaces on a sterile glass plane would facilitate the clinical workflow.
This project is strongly related to the Tangible Interaction Surface for Collaboration between Humans project.

3D user interfaces for medical interventions

3D user interfaces for medical interventions

This work group aims at practical user interfaces for 3D imaging data in surgery and medical interventions. The usual monitor based visualization and mouse based interaction with 3D data will not present acceptable solutions. Here we study the use of head mounted displays and advanced interaction techniques as alternative solutions. Different issues such as depth perception in augmented reality environment and optimal data representation for a smooth and efficient integration into the surgical workflow are the focus of our research activities. Furthermore appropriate ways of interaction within the surgical environment are investigated.
