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…
Actionable Guidance Outperforms Map and Compass Cues in Demanding Immersive VR Wayfinding
Apurv Varshney, Lily M. Turkstra, Jiaxin Su +5
Navigation aids are central to immersive virtual reality (VR) experiences that involve physical locomotion. Their effectiveness depends not only on how much spatial information the…
Static or Temporal? Semantic Scene Simplification to Aid Wayfinding in Immersive Simulations of Bionic Vision
Justin M. Kasowski, Apurv Varshney, Michael Beyeler
Visual neuroprostheses (bionic eye) aim to restore a rudimentary form of vision by translating camera input into patterns of electrical stimulation. To improve scene understanding…
Simulated prosthetic vision confirms checkerboard as an effective raster pattern for epiretinal implants
Justin M. Kasowski, Apurv Varshney, Roksana Sadeghi +1
Spatial scheduling of electrode activation ("rastering") is essential for safely operating high-density retinal implants, yet its perceptual consequences remain poorly understood.…
Navigating the Last Mile: Evaluating Head- and Cane-Mounted Cameras for Egocentric Spatial Awareness
Apurv Varshney, Lucas Nadolskis, Tobias Höllerer +1
Robust navigational guidance is an important XR application for both sighted and non-sighted populations. In this paper, we mainly focus on blind pedestrians, who continue to face…
