We investigated the influence of body shape and pose on the perception of physical strength and social power for male virtual characters. In the first experiment, participants judged the physical strength of varying body shapes, derived from a ...

Selecting color schemes for game objects is an important task. It can be valuable to game designers to know what colors are preferred. Principles of color theory are important to select appropriate colors. This paper presents a perceptual experiment ...

In this paper, we conducted a perceptual experiment to determine if specific personality traits can be portrayed through eye and head movement in the absence of other facial animation cues. We created a collection of eye and head motions captured from ...

The majority of the materials we encounter in the real-world have variable reflectance when rotated along a surface normal. This view and illumination azimuthally-variable behavior is known as visual anisotropy. Such behavior can be represented by a ...

The human ability to perceive materials and their properties is a very intricate multisensory skill and as such not only an intriguing research subject, but also an immense challenge when creating realistic virtual presentations of materials. In this ...

Physical simulation and rendering of cloth is widely used in 3D graphics applications to create realistic and compelling scenes. However, cloth animation can be slow to compute and difficult to specify. In this paper, we present a set of experiments in ...

Perceiving an accurate sense of absolute scale is important for the utility of virtual environments (VEs). Research shows that absolute egocentric distances are underestimated in VEs compared to the same judgments made in the real world, but there are ...

Many have experienced vastness, the feeling when the visual space seems to extend without limits away from you, making you feel like a small element within the space. For over 200 years, people have been writing about this experience, for example ...

Distance perception is important for many virtual reality applications, and numerous studies have found underestimated egocentric distances in head-mounted display (HMD) based virtual environments. Applying minification to imagery displayed in HMDs is a ...

Different from classic reconstruction of physical depth in computer vision, depth for 2D-to-3D stereo conversion is assigned by humans using semi-automatic painting interfaces and, consequently, is often dramatically wrong. Here we seek to better ...

There is growing interest in capturing and projecting movies at higher frame rates than the traditional 24 frames per second. Yet there has been little scientific assessment of the impact of higher frame rates (HFR) on the perceived quality of cinema ...

We have developed an interactive 4-D visualization system that employed the principal vanishing points operation as a method to control the movement of the eye-point and the change in the viewing direction in 4-D space. Different from conventional 4-D ...

Contemporary game engines offer an outstanding graphics quality but they are not free from visual artefacts. A typical example is aliasing, which, despite advanced antialiasing techniques, is still visible to the game players. Essential deteriorations ...

Several perceptually-based quality metrics have been introduced to predict the global impact of geometric artifacts on the visual appearance of a 3D model. They usually produce a single score that reflects the global level of annoyance caused by the ...

Humans rely heavily on spatial information to perform everyday tasks. Developing good spatial understanding is highly dependent on how the viewer's attention is deployed to specific locations in a scene. Bailey et al. [2009] showed that it is possible ...

In this paper, we use an inexpensive wearable device called the Myo armband (199 USD) to implement a simple arm swinging algorithm that allows a user to freely explore an HMD-based virtual environment. Using a spatial orientation task we directly ...

Animated digital self-representations of the user in an immersive virtual environment, a self-avatar, have been shown to aid in perceptual judgments in the virtual environment and to provide critical information for people deciding what actions they can ...

Collaborative immersive virtual environments allow the behavior of one user to be observed by other users. In particular, behavior of users in such an environment is represented by each user possessing a self-avatar, a digital representation of ...

This study explored whether people misremember having seen a physical object when they actually had viewed a virtual one in augmented reality (and vice versa). Participants viewed uniquely shaped objects in a virtual form or a physical, 3D-printed form. ...

Facial color and texture make the impressions of facial look and attractiveness (e.g. gorgeous, sophisticated and warm-hearted). These impressions can be affected by facial makeups, including face foundation, lip-makeup, eye-makeup, eyebrow-makeup, and ...

Virtual reality headsets and immersive head-mounted displays have become commonplace and have found their applications in digital gaming, film and education. An immersive perception is created by surrounding the user of the VR system with photo-...

Recently, there has been an increasing research interest on thermal feedback. This includes utilizing thermal systems as simple messaging tools, such as: a system that uses temperature to present the importance of messages [Wilson G. 2012] and help ...

Virtual reality has reached the consumer market and exhibited the potential to become a large social and commercial platform for mainstream markets. New, low-cost devices for virtual reality or mixed reality such as the Oculus Rift, Sony's Project ...

Despite the elusive term "Uncanny Valley", research in the area of appealing virtual humans approaching realism continues. The theory suggests that characters lose appeal when they approach photorealism (e.g., [MacDorman et al. 2009]). Realistic virtual ...

In head-mounted display systems, the confined size of the tracked space limits users from navigating larger virtual environments than the tracked physical space. Previous work suggests this constraint could be broken by asking users to back up or turn ...

We convey a tremendous amount of information vocally. In addition to the obvious exchange of semantic information, we unconsciously vary a number of acoustic properties of the speech wave to provide information about our emotions, thoughts, and ...

Immersive virtual environments (VEs) allow people to experience situations which because of danger, expense, time, or distance would not otherwise be available. Moreover, IVEs have been shown to be useful tools for learning and training. However, there ...

Immersive virtual environments (IVEs) provide an opportunity for humans to learn and to experience a place, which because of time, distance, danger, or expense, would not otherwise be available. Since navigation is the most common way users interact ...
