The Mobile Revolution and Real-World Integration (2006-2014)
This era is largely defined by the burgeoning presence of mobile AR and a strong drive towards integrating AR/MR into practical, real-world scenarios across various sectors. The shift to mobile phones as AR platforms became a significant trend, as evidenced by "Bringing Augmented Reality to Mobile Phones (2007)" and "Making Augmented Reality Practical on Mobile Phones, Part 1 & 2 (2009)." This brought new challenges and opportunities for ubiquitous AR ("Architectures for untethered augmented reality using wearable computers (2006)") and broader consumer adoption, including social gaming ("Capture the Flag: Mixed-Reality Social Gaming with Smart Phones (2006)").
Beyond mobile, there was a concerted effort to enhance the robustness, accuracy, and real-time performance of AR systems, with titles like "Tracking errors in augmented reality (2007)" and "Towards visual-inertial SLAM for mobile augmented reality (2009)" highlighting these ongoing technical pursuits. Applications deepened within industrial settings, moving from general production to "Computer Augmented Reality in der technischen Instandhaltung (2007)," "Augmented Reality based Factory Planning (2009)," and even warehouse operations with "Pick-by-vision (2010)." Healthcare applications continued to advance, with specific focuses on "Laparoscopic Surgery (2007)" and "image-guided interventions (2009)." The concept of user experience (UX) and human-computer interaction (HCI) gained increasing attention, with titles focusing on "Usability Engineering (2008)" and "Optimizing the user experience of mobile Augmented Reality applications (2012)." The development of authoring tools also became a recognized need to facilitate content creation ("Creating augmented reality authoring tools (2012)").
Maturation, Human Factors, and Emerging Intelligence (2015-2018)
This period saw AR/MR mature significantly, driven in part by the arrival of consumer-grade head-mounted displays like the Microsoft HoloLens, explicitly mentioned in "Mixed Reality with Microsoft HoloLens (2016, 2017)." The conversation shifted from if AR would be practical to how it would be integrated seamlessly and intelligently. A key theme was the increasing focus on human factors and user interaction, delving into aspects like "Legibility in Industrial AR (2015)," "Multimodal Interaction (2016)," "Natural freehand grasping of virtual objects (2018)," and even designing for "older adults (2018)." Collaboration remained a strong thread, with research on "Supporting Multi-User Interaction in Co-Located and Remote Augmented Reality (2016)" and "Collaborative Augmented Reality (2018)."
