Even conservative forecasters predict the imminent wave of Augmented/Virtual/Mixed Reality applications to extend far beyond gaming. Education, health care, analytics, marketing—immersive environments are poised to provide productivity gains in multiple sectors, eventually replacing conventional interfaces with gestures, gaze and natural language processing. The Software Engineering and Programming Language communities have only just begun to fully engage within this new paradigm. The Software for Augmented and Virtual Reality (SAVR) workshop will be designed to help bridge this gap. Participants will submit a position paper outlining the SE/PL challenges they have either encountered or anticipate in this space.
