ISMAR invites contributions advancing Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR). ISMAR 2026 will cover industry and research activities related to the full range of immersive technologies (AR, MR, and VR), including everything from interfaces in the real world to fully immersive experiences, and beyond. This range extends far beyond traditional published work in AR, encompassing precise 3D tracking, visual display, and real-time performance. We specifically invite contributions that advance all aspects of AR / MR / VR technology and user experiences. All submissions must demonstrate an explicit, clear, and significant connection to AR, MR, or VR concepts, systems, or experiences.
