Moving Beyond the Flat Screen: Opportunities and Challenges of Extended Reality for Studying Human Brain and Behavior
Tom Bullock, Radha Kumaran, You-Jin Kim +3
Much of what we know about human perception and cognition comes from austere experimental settings: static stimuli presented to sedentary observers on flat monitors, complex respon…
Exploring Object Recall in an Object-Rich AR Office Scene
Sangita Kunapuli, Shane Dirksen, Radha Kumaran +4
Augmented reality (AR) changes how users perceive and attend to their surroundings. Prior work suggests AR can reduce attention to the physical world, but it remains unclear whethe…
SABER: Spatial Attention, Brain, Extended Reality
Tom Bullock, Emily Machniak, You-Jin Kim +9
Tracking moving objects is a critical skill for many everyday tasks, such as crossing a busy street, driving a car or catching a ball. Attention is a key cognitive function that su…
Scene Awareness While Using Multiple Navigation Aids in AR Search
Radha Kumaran, You-Jin Kim, Emily Machniak +5
Augmented reality (AR) allows virtual information to be presented in the real world, providing support for numerous tasks including search and navigation. Allowing users access to…
Investigating Search Among Physical and Virtual Objects Under Different Lighting Conditions
You-Jin Kim, Radha Kumaran, Ehsan Sayyad +4
By situating computer-generated content in the physical world, mobile augmented reality (AR) can support many tasks that involve effective search and inspection of physical environ…
On the Go with AR: Attention to Virtual and Physical Targets while Varying Augmentation Density
You-Jin Kim, Radha Kumaran, Jingjing Luo +3
Augmented reality is projected to be a primary mode of information consumption on the go, seamlessly integrating virtual content into the physical world. However, the potential per…
The Impact of Navigation Aids on Search Performance and Object Recall in Wide-Area Augmented Reality
Radha Kumaran, You-Jin Kim, Anne E Milner +3
Head-worn augmented reality (AR) is a hotly pursued and increasingly feasible contender paradigm for replacing or complementing smartphones and watches for continual information co…
Modeling Object Attention in Mobile AR for Intrinsic Cognitive Security
Shane Dirksen, Radha Kumaran, You-Jin Kim +2
We study attention in mobile Augmented Reality (AR) using object recall as a proxy outcome. We observe that the ability to recall an object (physical or virtual) that was encounter…
XARP Tools: An Extended Reality Platform for Humans and AI Agents
Arthur Caetano, Radha Kumaran, Kelvin Jou +2
Building XR-AI research prototypes requires navigating two largely separate ecosystems. Mainstream XR development relies on C#/C++ and game engines, while AI development is centere…
Agentic Workflows for Conversational Human-AI Interaction Design
Arthur Caetano, Kavya Verma, Atieh Taheri +5
Conversational human-AI interaction (CHAI) have recently driven mainstream adoption of AI. However, CHAI poses two key challenges for designers and researchers: users frequently ha…
Multimodal 3D Fusion and In-Situ Learning for Spatially Aware AI
Chengyuan Xu, Radha Kumaran, Noah Stier +2
Seamless integration of virtual and physical worlds in augmented reality benefits from the system semantically "understanding" the physical environment. AR research has long focuse…
