The Effect of the Vergence-Accommodation Conflict on Virtual Hand Pointing in Immersive Displays
(Assoc Computing Machinery, 2022)
Previous work hypothesized that for Virtual Reality (VR) and Augmented Reality (AR) displays a mismatch between disparities and optical focus cues, known as the vergence and accommodation conflict (VAC), affects depth ...
My Eyes Hurt: Effects of Jitter in 3D Gaze Tracking
(IEEE Computer Soc, 2022)
Jitter, small fluctuations in the signal, is one of the major sources for a decrease in motor performance and a negative user experience in virtual reality (VR) systems. Current technologies still cannot eliminate jitter ...
Measuring the Effect of Stereo Deficiencies on Peripersonal Space Pointing
(IEEE Computer Soc, 2023)
State-of-the-art Virtual Reality (VR) and Augmented Reality (AR) headsets rely on singlefocal stereo displays. For objects away from the focal plane, such displays create a vergence-accommodation conflict (VAC), potentially ...
Performance Analysis of Saccades for Primary and Confirmatory Target Selection
(Assoc Computing Machinery, 2022)
In eye-gaze-based selection, dwell suffers from several issues, e.g., the Midas Touch problem. Here we investigate saccade-based selection techniques as an alternative to dwell. First, we designed a novel user interface ...
