The present study is designed to test the role of immersion and media content in the sense of presence. Specifically, we are interested in the affective valence of the virtual environments. This paper describes an experiment that compares three immersive systems (a PC monitor, a rear projected video wall, and a head-mounted display) and two virtual environments, one involving emotional content ...

OBJECTIVE This study evaluated the influence of light sources and immersion media on the color stability of a nanofilled composite resin. MATERIAL AND METHODS Conventional halogen, high-power-density halogen and high-power-density light-emitting diode (LED) units were used. There were 4 immersion media: coffee, tea, Coke® and artificial saliva. A total of 180 specimens (10 mm x 2 mm) were pre...

OBJECTIVE The aim of this in vitro study was to evaluate the color stability of a nanofill composite resin (Filtek Z350) in different immersion media. MATERIALS AND METHODS Twelve resin-based composite specimens were prepared using a silicon cylindrical mold measuring congruent with 1mm of thickness and congruent with 10mm of diameter. Specimens were light-cured for 40 s from both sides using...

Revolutionary developments in communication and information technologies, coupled with the transition from traditional media into new media, create new mediums of the information age which are capable of offering interactive user participation in communication processes. Frontiers of these new mediums are virtual reality technologies which can be considered as the ultimate form of interaction b...

Digital games appear to motivate players intrinsically. Of various game features, fantasy in particularly plays a crucial role in enhancing motivation and is a key factor in immersion in gameplay. As with its inherent value, fantasy also plays a vital role in distinguishing digital games itself from other media. Despite its significance, fantasy has received little attention, and this concept i...

A person is immersed when they feel part of an environment they experience and influence. While virtual immersion systems are usually designed on a case by case basis, and are not easily reusable or scalable, our goal is to specify and develop a framework for the design and integration of immersive systems. We address the issues raised in the design and implementation of the middleware componen...

Presently, designers of interactive narratives and video games have only a slender understanding of the aesthetic experiences their audiences and users seek. Using schema theory, this study articulates the two varieties of aesthetic pleasures that users of interactive works enjoy: immersion and engagement. It uses schema theory to define the characteristics of immersion and engagement in both c...

A perfusion chamber is described with which a tissue culture can be irrigated successively with different immersion media. Only 1-2 ml. of medium are required for each change, which can be accomplished within 1 minute. Simplicity of design permits speed and economy in manufacture. Perfusion by suction instead of by positive pressure has eliminated certain drawbacks of previous designs. Mixing e...

The resolution of an optical microscope is restricted by the diffraction limit, which is approximately 200 nm for a white light source. We report that sub-diffraction-limited objects can be resolved in immersion liquids using a microsphere optical nanoscopy (MONS) technique. Image magnifications and resolutions were obtained experimentally and compared in different immersion liquids. We show th...
