    A Dense Statistical Model of Facial Soft Tissue Thickness
    (INFORMATIK 2017, 2017) Gietzen, Thomas; Brylka, Robert; Schwanecke, Ulrich; Schömer, Elmar
    Ambient intelligence become more and more ubiquitous and help people achieving a more natural interaction with their electronically enhanced environment. One vital natural interface between humans and ambient intelligence are embodied conversational agents. Thereby, the acceptance of these virtual characters is all the greater, the more natural they look and behave. Since humans pay particular attention to the face, a natural-looking animation of the face is very important. In this paper we present a dense statistical model of facial soft tissue thickness that can be used to build accurate physics-based facial animations. The presented model not only can help to generate more natural facial animations of virtual characters but also can be used in other research domains such as forensic anthropology or medicine. Especially in the field of dentistry and orthodontics in particularly younger people and children are increasingly examined using X-ray technology. Thereby more and more volumetric images are generated, which further increase cost as well as the induced radiation dose. Here, for example, our statistical model can provide the basis for a new volumetric reconstruction process of a human’s facial bones in a cost-effective manner and with low radiation exposure.

    Exploring the Benefits of Holographic Mixed Reality for Preoperative Planning with 3D Medical Images
    (Mensch und Computer 2019 - Workshopband, 2019) Mast, Marcus; Kaup, Ina; Krüger, Sebastian; Ullrich, Christian; Schneider, Robert; Bay, Susanne
    Today surgeons usually prepare for operations by inspecting sets of 2D radiological images. This means that they need to form a 3D mental model from 2D data. The lack of depth perception afforded by 2D images is an issue especially in complex cases. New and improved approaches are therefore an area of active research. Recent advances in both holographic mixed reality and 3D visualization techniques represent an interesting opportunity to address this issue. The article describes our ongoing efforts to support surgeons in preoperative planning by developing a medical volume viewer for Microsoft’s HoloLens 2 headset. The app combines the state-of-the art image quality of cinematic volume rendering with the excellent depth perception in holographic headsets and will allow new ways of planning surgeries and interacting with medical volumes.
