In the broader field of human behavior studies, there are several trade-offs for on-site experiments. To be tied to a specific location can limit both availability and diversity participants. However, current future technological advances make it possible replicate real-world scenarios in virtual environment up certain level detail. How these differences add affect cross-media validity findings...

With the rapid development of virtual reality (VR) technology, VR headsets, a.k.a. Head-Mounted Displays (HMDs), are widely available, allowing immersive 3D content to be viewed. A natural need for truly is allow bidirectional communication: user should able interact with world using facial expressions and eye gaze, in addition traditional means interaction. The typical application scenario inc...

In this paper, we propose and design a new Head Mounted Display (HMD) that provides a large field of view with a high resolution insert. Previously, this type of HMDs has been designed using mechanical or sequential scanning devices. Our HMD uses only electronic devices that can be easily integrated with the optical components. We describe the design principles and envisioned applications of ou...

While the augmentation of head-mounted displays (HMDs) with eye-tracking (ET) capabilities adds challenges to designing compact and portable displays, a systematic approach to integration offers opportunities to improve overall performance and robustness. To investigate the design and optimization of illumination schemes in an ET-HMD system, we present a simulated eye illumination and imaging s...

Head-mounted displays (HMDs) are highly immersive display devices which are increasingly targeted towards consumer-level video games, E-learning, training and other forms of digital entertainment. Despite the hardware now being available, quality factors — particularly latency — are still issues in large part due to consumer graphics hardware being tailored for throughput instead of latency, an...

Search in and presentation of multimedia collections is an important and complex task. Often it involves various search strategies and the visualization of found object collections. Technically, search strategies can be formulated using distance measures between object pairs. In this paper we propose the use of a projection based method to dynamically arrange a set of objects (here images) give...

In the context of image-guided surgery, augmented reality (AR) represents a ground-breaking enticing improvement, mostly when paired with wearability in case open surgery. Commercially available AR head-mounted displays (HMDs), designed for general purposes, are increasingly used outside their indications to develop surgical guidance applications ambition demonstrate potential The proposed lite...

A psychophysical experiment was conducted to compare the discomfort luminance level and brightness of a head-mounted display (HMD). The results showed that as size HMD stimulus increased, both decreased, but influence change more dramatic on than brightness. This study provide comfortable for HMDs, adaptation should be considered. However, it cannot predicted in terms

Head-mounted displays (HMDs) allow users to explore virtual environments (VEs) from an egocentric perspective. In order to present a realistic view, the rendering system has to be adjusted to the characteristics of the HMD, e. g., the display’s field of view (FOV), as well as to characteristics that are unique for each user, in particular, the interpupillary distance (IPD). In the optimal case,...
