We invite laboratories from all areas of xR (Augmented, Virtual, and Mixed Reality) and 3DUI (3D User Interface) to apply for presenting in the "Pitch Your Lab" session at the 17th IEEE International Symposium on Mixed and Augmented Reality (ISMAR) in Munich. The presentation might describe laboratory's research area, members, equipment, current and past research projects, industrial and academic collaborations, and open positions. Applications must be submitted through a web application form with an optional one-page lab introduction material. Accepted presentations will require at least one presenter to attend the conference to orally present an introduction to the lab in the "Pitch Your Lab" session. Presentations and lab introduction materials will not be included in the proceedings, but will be made accessible through conference website.
