Do Head-Mounted Display Stereo Deficiencies Affect 3D Pointing Tasks in AR and VR?

IEEE Conference on Virtual Reality and 3D User Interfaces, 2019
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 depth cues, which then also affect virtual hand interaction in peri ...

Immersive Collaborative Analysis of Network Connectivity: CAVE-style or Head-Mounted Display?

IEEE Transactions on Visualization and Computer Graphics, 2017
High-quality immersive display technologies are becoming mainstream with the release of head-mounted displays (HMDs) such as the Oculus Rift. These devices potentially represent an affordable alternative to the more traditional, centralised CAVE-style ...

Head Mounted Displays for Medical Use

Journal of Display Technology, 2008
Head Mounted Displays have been used in various forms to assist surgeons and other medical personnel to support and improve visualization of the work site. Historically, many of these were of inadequate resolution, bulky, cave-like and heavy and they, deservedly, received limited acceptance.

Low-cost, smartphone-based frequency doubling technology visual field testing using a head-mounted display

British Journal of Ophthalmology, 2019
Background Current visual field screening machines are bulky and expensive, limiting their accessibility, affordability and use. We report the design and evaluation of a novel, portable, cost-effective system for glaucoma screening using smartphone-based

Image guided percutaneous spine procedures using an optical see-through head mounted display: proof of concept and rationale

Journal of NeuroInterventional Surgery, 2018
Background and purpose Optical see-through head mounted displays (OST-HMDs) offer a mixed reality (MixR) experience with unhindered procedural site visualization during procedures using high resolution radiographic imaging.

Emotion Recognition in Gamers Wearing Head-mounted Display

IEEE Conference on Virtual Reality and 3D User Interfaces, 2019
Wearing head-mounted display (HMD) makes previous research regarding emotion recognition using machine vision ineffective since they utilized entire face images for training.

Natural Perspective Projections for Head-Mounted Displays

IEEE Transactions on Visualization and Computer Graphics, 2011
The display units integrated in today's head-mounted displays (HMDs) provide only a limited field of view (FOV) to the virtual world. In order to present an undistorted view to the virtual environment (VE), the perspective projection used to render the VE has to be adjusted to the limitations caused by the HMD characteristics.

Contrast measurement of head-mounted displays

Optical Engineering, 2002
We present a way to measure the contrast of helmet- mounted displays. Standards exist for direct view flat panel displays and projection displays, but head-mounted displays do not seem to be covered by the standards yet. We start by discussing a basic setup (4-mm aperture, lens, detector) with the aperture residing in the exit pupil of the display. A 4

Optical schemes of the head-mounted displays

Optical Modeling and Performance Predictions IX, 2017
Recently there is a growing interest to the head up and head mounted systems. There are many variants of implementation of the head-mounted display system for various purposes with different characteristics. The configuration of the system is highly affected by both type of the image generator and the type of the used combiner.
