ISMAR 2015, the premier conference for Augmented Reality (AR) and Mixed Reality (MR), will be held in beautiful Fukuoka, Japan. The theme of this year’s conference is "Augmentation Without Boundaries". ISMAR is responding to the recent explosion of commercial and research activities related to AR, MR, and Virtual Reality (VR) by continuing the expansion of its scope that started last year. ISMAR 2015 will cover the full range of technologies encompassed by the MR continuum, from interfaces in the real world to fully immersive experiences. This range goes far beyond the traditional definition of AR, which focused on precise 3D tracking, visual display, and real-time performance. We specifically invite contributions from areas fundamental to AR/VR/MR, including Computer Graphics, Human-Computer Interaction, Psychology, Computer Vision, and Optics.
