In recent years, Virtual Reality (VR) has become increasingly popular in research, entertainment, and education. VR systems allow one or multiple users to interact with a computer-simulated environment presented by an immersive display medium. In this course, you will study the theoretical, technical, and applied foundations of modern Virtual Reality systems.

The course starts by teaching the essentials of computer graphics and stereoscopic viewing required to realize VR applications. After that, you will explore the fundamentals of 3D input devices and 3D interaction techniques, including selection, manipulation, and navigation in virtual environments. The final part of the course builds on the previously acquired knowledge and focuses on collaborative VR systems for multiple collocated and distributed users.

The lecture will be accompanied by lab classes, which make use of the latest Virtual Reality technology such as multi-viewer 3D projection systems and high-resolution head-mounted displays. It will be your task to implement and evaluate various 3D interaction techniques using these immersive display systems, six degrees of freedom tracking, and 3D input devices.

    Lab Class Materials

    The lab class will be administered on Moodle. Please follow the link and register with the credentials provided in the first lecture to participate.

    The introductory slides of the first lab class can be found here.


    Your grade for this course is determined by the successful completion of the lab class (1/3) and a final oral examination (2/3).

    During the lab class, you will be asked to complete both theory and practice assignments. You need to achieve at least half of the points over all graded assignment sheets to pass. The average grade across all assignments is your total grade for the lab class. Group work in pairs of two students is permitted.

    The final examination is an oral discussion covering all topics of the lecture and lab class. Appointments for oral examinations will be made individually at the end of the course.

    The following scheme is applied to convert percentages to grades:

    1.0>= 95.0
    1.1[93.5 - 95.0)
    1.2[92.0 - 93.5)
    1.3[90.5 - 92.0)
    1.4[89.0 - 90.5)
    1.5[87.5 - 89.0)
    1.6[86.0 - 87.5)
    1.7[84.5 - 86.0)
    1.8[83.0 - 84.5)
    1.9[81.5 - 83.0)
    2.0[80.0 - 81.5)
    2.1[78.5 - 80.0)
    2.2[77.0 - 78.5)
    2.3[75.5 - 77.0)
    2.4[74.0 - 75.5)
    2.5[72.5 - 74.0)
    3.0[65.0 - 66.5)
    4.0[50.0 - 51.5)
    5.0 (fail)[00.0 - 50.0)

    Final Project (optional)

    The final project (graded separately and awarded additional 1.5 ECTS) requires the participants to apply the obtained theoretical and practical skills of the course in the design, implementation and presentation of an individual small research project. In particular, you will be asked to develop a concept, come up with an effective and efficient implementation and present your results in a concise talk. This is an invaluable opportunity to work on an interesting topic of your choice with the state-of-the-art VR-hardware available in our lab like head-mounted displays, multi-user projection systems and multi-touch tabletops. Group work in pairs of two students is permitted.
