The use of smartphones for activities like watching movies and playing games has become commonplace because of the flexibility that devices offer citizens in their increasingly overloaded daily routines. As a consequence, the market has explored the creation of accessories to enhance the user experience in performing these tasks. The present work selected as context the practice of watching movies...
The smooth motion parallax of light field displays is one of the most critical enablers of the glasses-free auto-stereoscopic 3D experience. This smoothness originates from an acceptable degree of angular resolution, which is derived from the number of views visualized in the given field of view. However, if human observers view the content without any movement, the requirement for angular resolution...
Video summarization is a timely and rapidly developing research field with broad commercial interest, due to the increasing availability of massive video data. Relevant algorithms face the challenge of needing to achieve a careful balance between summary compactness, enjoyability, and content coverage. The specific case of stereoscopic 3D theatrical films has become more important over the past years,...
The effect of ambient light source and display type on visual fatigue was investigated. The tested ambient illumination included 120Hz full modulated LED light source, normal fluorescent light source and dark environment. And the tested display type included 2D and 3D based on shutter glasses. Visual fatigue was measured with subjective ratings (12 symptoms, considering general discomfort and eye...
We describe a method to subdivide two-manifold, non-convex object meshes using a Voronoi volume. The Voronoi volume is divided into Voronoi subvolumes to a desired density. A depth map mask generated from the object mesh is then used to remove any excess subvolumes that do not intersect the mesh. The mesh is then intersected with each Voronoi subvolume using triangle-triangle intersection. The surface...
In order to study the impact of 3D subtitle characteristics on visual comfort, this paper included two experiments. In experiment 1, the study was on the impact of 3D subtitle fonts on visual comfort. The results showed the 3D subtitle fonts could not reduce the visual comfort. The subtitles with Official Script font, NSimSum font and bold font had no significant differences on visual comfort. And...
The study investigated how the depth of 3D subtitles impacted the viewers' 3D experience. The disparities of the subtitles were chosen from 7.56', 15.12', 22.32', -7.56', -15.12' and -22.32'. The results showed that subjects felt more fatigue when seeing subtitles with uncrossed disparities than that with crossed disparities. Regardless of using crossed disparities or uncrossed disparities, the subtitles...
There is a wide range of screen sizes (from 3 to 30 meters) used in movie theaters. How can we properly choose 3D shooting parameters so that the movie may be viewed equally well in digital 3D cinemas, on the Giant Screen, on home TV sets, and on mobile phones? The proposed parameter selection algorithm for 3D shooting offers a selection independent of shooting methods or equipment by replacing absolute...
The use of stereoscopic display has increased in recent times, with a growing range of applications using 3D videos for visual entertainment, data visualization, and medical applications. However, stereoscopic 3D video can lead to adverse reactions amongst some viewers, including visual fatigue, headache and nausea; such reactions can further lead to Visually Induced Motion Sickness (VIMS). Whilst...
This essay provides a comparative study on aesthetic between 3D stop-motion animation and 3D Computer graphic animation. These two animation forms produced in different pipelines and outcomes. Highlighting key aesthetic principles of animation and fueled by statements that written by Power who underlines the importance of expressiveness in animation and engagement of viewer's emotion, author draws...
The communication of museums, with the aim to engage and attract a wider audience, is undergoing a radical change, seeking in ICT a help. The joint exhibition “The Etruscans and the Afterlife”, hosted by the National Etruscan Museum of Villa Giulia and the Museum of the History of Bologna - Genus Bononiae - presents a strong commitment towards a renewed communicational effort of this kind, merging...
Humans sense the surrounding environment through five senses: sight, hearing, taste, smell and touch. This is valid not only for real life but also when one is exposed to virtual environments. It already exists systems that exploit the sensorial stimulation of more than one sense, however there are no available low-cost solutions that allow creative professionals to create and visualize multisensory...
Symptoms of three-dimensional (3D) sickness, such as intoxication and eye fatigue, have been observed in subjects viewing 3D films and vary according to the image quality and visual environment. In addition, the influence of stereoscopic vision on the incidence of 3D sickness has not been explored sufficiently. Therefore, it is important to examine the safety of viewing virtual 3D content. The present...
The function of depth perception may be related to the ability to perform vergence eye movements during the viewing of three-dimensional stereoscopic movies.
There have been reports that some people who watch 3D movies experience motion sickness symptoms. In this research work, the change in dynamics of mental activity of subjects is evaluated to understand the reason behind the sickness. Cortical activity of the brain recorded from subjects who watch a stimulus (movie) on 2D and 3D TV. We propose that brain waves recorded using EEG device can be analysed...
3D cinema is heading towards self-sufficient maturity both technically and aesthetically. In this paper, I will undertake a comparative analysis of the distinctions between 3D and 2D cinema based on a correlation between techniques of production and perceptual physiologies. Moreover, with reference to Siegfried Kracauer's classic remark about cinematic ontology that “the nature of film is the redemption...
While 3D cinema is becoming increasingly established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant interest. In this paper, we explain why the combination of accurate sound positioning and stereoscopic-3D images...
We propose "Mixticky," a scheme for browsing and recording memorandum-like sticky notes in a three-dimensional virtual space around a user with a smartphone. For intuitive browsing and recall of such memos and information, it is important to achieve browsability and contemporaneousness of the memos/information. Mixticky allows the user to place and peel off memos on a virtual balloon around...
Many people report visual fatigue and discomfort while watching 3D displays. This situation is aggravated when subtitles are involved. However, little concern has been given to the issue of how to properly place the subtitles in 3D movies. In our work, subjective assessment has been carried out for 3D movies, in order to find out how much in depth is the appropriate position for placing subtitles,...
The advent of 3D to the home raises a number of challenges beyond the basic display of an available stereo pair. A number of them are technical challenges, as for example the adaptation of various 3D content types to different display technologies. Other aspects relate to the Quality of Experience, involving observation conditions and observers. Indeed, a correct 3D perception for everyone cannot...
