Design of user evaluation of two travel metaphors in a VR environment. (Bachelor Thesis)
Design of user evaluation to be able to compare and evaluate the two implemented travel metaphors: Phone Based Motion Control Vs Steering and Driving. The two metaphors will be evaluated to each other quantitatively and qualitatively. To do that both metaphors should be integrated. An android phone has to be used for both metaphors (instead of tablet Pc in the second metaphor) and ART tracking has to be used in both metaphors (instead of orientation sensor in the first metaphor). | |
3D augmented virtuality sketching (DA/MA/BA)
Within the interdisciplinary project "Collaborative Design Platform" http://cdp.ai.ar.tum.de/, a large-scale multitouch table was developed to aid urban planning and prototyping. The table interacts with the user over a multitouch surface, and can also scan objects positioned on top of it in 2.5 dimensions. In order to enhance its presentation cababilities, an additional display will be added, which offers a 3D augmented virtuality perspective on the workspace, which reflects both the physical and the virtual aspect of the scene. The view can be controlled using a special 3D mouse. In addition, the user can sketch and draw directly on the virtual world presented on the new display. | |

Computational Modeling of Respiratory Motion Based on 4D CT (Master Thesis)
Respiratory lung motion has a serious impact on the quality of medical imaging, treatment planning and intervention, and radiotherapy. This motion not only reduces imaging quality, especially for positron emission tomography (PET), but also inhibits the determination of the exact position and shape of the target during radiotherapy. Based on prior knowledge of average tissue properties, patient-specific imaging (4D CT) and a surrogate signal, a computational motion model can be created. This enables researchers and developers to simulate and generate information about a respiratory phase not covered by the imaging procedure. Therefore, the internal deformation of the lung and its containing cancerous tissue can be computed and taken into account during further imaging acquisitions or radiotherapy. | |

Multitouch Gesten Leitfaden (Bachelor Thesis)
Multitouch Geräte, die mit Gesten bedient werden, werden immer beliebter. Die Anzahl der unterschiedlichen Gesten wächst dabei zunehmend. Mittlerweile ist ein ganzer Dschungel an verschiedensten Gesten vorhanden. Diese Arbeit soll Licht in das Dunkel bringen. Ein Überblick über die verschiedenen Gesten soll gegeben werden. Welche Geste wird für welche Interaktionen verwendet? Woher stammen die Gesten? Auf welchen Geräten werden die Gesten ausgeführt? (Mobiltelefone, TabletPCs?, Grafik Tablet, Magic Mouse, Multitouch Tisch…). Da es sich bei dieser Arbeit um eine theoretische Arbeit handelt, liegt der Fokus auf der Literaturrecherche und dem Auswerten der Literatur sowie dem der entsprechenden visuellen Darstellung der Daten. Letztenendes soll ein Leitfaden für den Einsatz von Gesten entwickelt werden. | |

Point- and Linefeature based Bundle Adjustment for a Realtime-Trackingsystem (DA/MA/BA)
Die Bündelausgleichsrechnung ist eine Technik um die Genauigkeit von 3D-Rekonstruktionen zu verbessern. Sie kommt bei verschiedenen Problemstellungen zum Einsatz, unter anderem bei Trackingsystemen. Mit der Bündelausgleichsrechnung auf der Basis von Punktmerkmalen wurden bisher schon gute Ergebnisse erzielt. Durch die Berücksichtigung von Linien im Bild, die zusätzliche Informationen über eine Szene enthalten, soll die Qualität der Bündelausgleichsrechnung in einem Trackingsystem verbessert werden. Dadurch sollen sich neue Möglichkeiten und Anwendungsgebiete eröffnen. Aufgabe dieser Arbeit ist es, Punkt- und Linienmerkmale in den einzelnen Bildern zu finden, Korrespondenzen zwischen den einzelnen Bildern herzustellen und diese Informationen dann in die 3D Rekonstruktion der Punkte, Linien und Kameras sowie deren Verfeinerung durch die Bündelausgleichsrechnung zu integrieren. | |
F the FRAVE (DA/MA/BA)
The FRAVE is a Fully Reconfigurable CAVE at the Showroom I-Tüpferl in the Magistrale of the computer science building. It is mainly driven by a 3D terrain rendering software that uses Equalizer for parallelization of rendering. Our approach goes further. The F stands for Fully Equalizer does not yet support dynamic reconfiguration of displays. Your honorable job is to extend Equalizer to make the FRAVE what it is. | |
Entwicklung eines Prozesses zur Kalibrierung von Datenhandschuhen in Virtual Environments (Master Thesis)

Follow The Magic Lense (DA/MA/BA)
Interaction in an immersive virtual environment (IVE) such as a CAVE or in our case FRAVEis an important issue to investigate. To be able to select and manipulate the virtual object displayed in VR world. The User can do it through the Magic Lenses, Where the Frave provide the contextual view and the tracked Handheld device the focus view. The view frustum is calculated using handheld device position and orientation. | |
Gestyboard 2.0 (Master Thesis)
This theses is about continuing the implementation of a multitouch-keyboard (the Gestyboard) based on gestures which can be used with 10 fingers at the same time. A well-known problem in this field is the lack of haptic feedback. This is the reason why the performance of a virtual keyboard is much lower than the performance of a real keyboard. The goal of this thesis is to get to know if users are able to be as performant with the new innovative multitouch keyboard as with the real keyboard. Therefore, different alternatives of the same concept should be implemented and evaluated. There is already a concept defined but students are welcome to bring their your own ideas into the project. | |

Counting data on a map on a multitouch table (DA/MA/BA)
Within the project SpeedUp (http://www.speedup-projekt.de/) we develop a map application for mass casualty incidents. On this map application the user should be able to count the data on the map in a very short time. The task of the thesis is to develop different variations for counting the data on the map. Finally the different implementations should be evaluated. TISCH, a multitouch table, which includes an ftir multitouch sensor and shadow tracking developed by Florian Echtler should be used as hardware. As development framework Microsoft Blend and C# should be used. | |

Augmented Reality Game for Teaching Medical Skills (DA/MA/BA)
Augmented Reality (AR) is a very promising technology for training. Today 2D illustratio are used to teach complex three dimensional structures. AR allows to visualize object in 3D coregistered with the real world. In medicine, AR allows to view inside the patient an visualize organs directly on the patient. We have an existing AR system using a head mounted display (HMD) and a patient dummy. The goal of this project is to develope a game to teach medical skills by showing e.g. 2D slices and let the user select the corresponding slice from the physical phantom. | |
Bachelorarbeit: User-Interface für digitale Formulare (Diploma Thesis)
Im Rahmen des Forschungsprojektes SpeedUp ist ein User-Interface zu entwickeln, welches u.a. die besonderen Anforderungen von sogenannten Großschadensereignissen erfüllt. Als Plattform soll ein TabletPC (Touchscreen) verwendet werden. Diesbezüglich sind unterschiedliche Daten von beispielsweise Verletzten oder Rettungskräften nur mit Hilfe der Touch-Screen Oberfläche des TabletPCs einzugeben , so dass auch in zeitkritischen, instabilen Stresssituation die Einsatzkräfte in der Lage sind, die Formulare direkt am TabletPC auszufüllen und Daten vom Einsatzort an den Einsatzleiter weiterzugeben. | |
Visual Marker Based User Interface for the Operating Room (IDP)
In the last decades, many advanced computer-based navigation solutions, e.g. using external camera tracking for navigation and augmented reality visualization, and intra-operative visualization systems e.g. Camera Augmented Mobile C-arm (CamC), have been introduced and deployed in the operating room (OR) for surgical practice. However, very few computer-based systems have succeeded to become clinically accepted and even a small number of them were integrated into daily clinical routine. Interactions between surgeons and these advanced complex computer aided intervention (CAI) systems play an important role of successfully deploying systems in the OR. Traditional computer-user interaction hardware, e.g. mouse and keyboard, is very difficult and impractical to be used, since they are hardly sterilized. A cheaper and practical solution based on visual marker detection is proposed for the user interface of CAI systems. In this project, a visual marker based robust and friendly user interface must is designed and developed. The developed user interface is integrated into a CamC system and its functionalities are evaluated with the CamC system. | |
