The limitations of stereo display systems affect depth perception, eg, due to the vergence-
accommodation conflict or diplopia. We performed three studies to understand how stereo …

Most AR and VR headsets use stereoscopic displays to show virtual objects in 3D. However,
the limitations of current stereo display systems affect depth perception through conflicting …

While commercial Virtual Reality (VR) controllers are mostly designed to be held in a power
grip, previous research showed that using pen-like devices with a precision grip can …

Fitts' law and throughput based on effective measures are two mathematical models
frequently used to analyze human motor performance in a standardized pointing task, eg, to …

The vergence-accommodation conflict (VAC) limits user performance in current Virtual
Reality (VR) systems. In this paper, we investigate the effects of the VAC in a single-focal VR …

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 …

Even when in a static position, data acquired from 6 Degrees of Freedom (DoF) trackers is
affected by noise, which is typically called jitter. In this study, we analyzed the effects of 3D …

3D pointing is an integral part of Virtual Reality interaction. Typical pointing devices rely on
3D trackers and are thus subject to fluctuations in the reported pose, ie, jitter. In this work, we …

The trade-off between speed and accuracy in precision tasks is important to evaluate during
user interaction with input devices. When different sensory cues are added or altered in such …

Previous work has shown that the mismatch between disparity and optical focus cues, ie, the
vergence and accommodation conflict (VAC), affects virtual hand selection in immersive …
