As computer-driven display technology becomes more powerful and accessible, the online, virtual art gallery may provide a new platform for artists to exhibit their work. Virtual exhibits may afford opportunities for both the artist and the patron to display, view and perhaps purchase various digital art forms. The aim of this paper is to examine user interaction with digital artworks inside a virtual gallery space. We use a range of criteria to describe conditions for both the designer and the user of such a virtual display system. The paper describes a number of experiments where users interacted with a virtual art gallery and were then extensively interviewed and surveyed. Measures of what Manovich (2002) describes as ‘immersion' and what Slater et al (1994) would term ‘presence' are observed in relation to the user experience. The gallery is a three-dimensional graphic digital construction built in Second Life. The experiment aimed to describe and delineate the user's perception and navigation of space and compares their perception of art objects in the virtual environment to digital objects in a ‘real world' gallery. The data collected in this study provide the basis for a discussion of how users may perceive and navigate virtual objects and spaces in an online environment such as a game or art gallery. The results may be of use to those designing interactive three-dimensional environments.

Predicting Behavior

Discrepanices between perceived and actual distance may affect people's spatial behavior. In a previous study Nasar, using self report of behavior, found that segmentation (measured through the number of buildings) along the route affected choice of parking garage and path from the parking garage to a destination. We recreated that same environment in a three-dimensional virtual environment and conducted a test to see whether the same factors emerged under these more controlled conditions and to see whether spatial behavior in the virtual environment accurately reflected behavior in the real environment. The results confirmed similar patterns of response in the virtual and real environments. This supports the use of virtual reality as a tool for predicting behavior in the real world and confirms increases in segmentation as related to increases in perceived distance.

Augmented reality is defined as the technology in which virtual objects are blended with the real world and also interact with each other. Although augmented reality applications are used in many areas, the most important of these areas is the field of education. AR technology allows the combination of real objects and virtual information in order to increase students’ interaction with physical environments and facilitate their learning. Developing technology enables students to learn complex topics in a fun and easy way through virtual reality devices. Students interact with objects in the virtual environment and can learn more about it. For example; by organizing digital tours to a museum or zoo in a completely different country, lessons can be taught in the company of a teacher as if they were there at that moment. In the light of all these, this study is a compilation study. In this context, augmented reality technologies were introduced and attention was drawn to their use in different fields of education with their examples. As a suggestion at the end of the study, it was emphasized that the prepared sections should be carefully read by the educators and put into practice in their lessons. In addition it was also pointed out that it should be preferred in order to communicate effectively with students by interacting in real time, especially during the pandemic process.

Visualization Application

<p>In learning projectile motion and its velocity, students tend to look up a plain two-dimensional image in a science book. While there’s some educational props, yet they usually a very tradional ones and can not be used for real calculation. The utilization of Augmented Reality (AR) in educational method may raise curiosity and gives a unique way in learning projectile motion as the motion can be seen in a three dimensional. Augmented Reality itself is a combination of real world and virtual objects. This application uses the Vuforia SDK that able to blend the real world and virtual objects. Through this application, we were able to simulate projectile motion and its velocity in more realistic way, have slightly interaction with the reality, and gets input from user so they can learn and see the result of the parameter that they entered. Thus, with the advantage of AR the application gives a more realistic feel compared to the existing ones available in public as it could receive any input and show the output in AR. </p>

Laser scanners offer a fast and simple way of collecting large amounts of geometric data from real-world objects. Although this aspect makes them attractive for design and reverse engineering, the laser-scanner data is often noisy and not partitioned into meaningful surfaces. A good partitioning, or segmentation, of the scanner data has uses including feature detection, surface boundary generation, surface fitting, and surface reconstruction. This paper presents a method for segmenting noisy three-dimensional surface meshes created from laser-scanned data into distinct regions closely approximated by explicit surfaces. The algorithm first estimates mesh curvatures and noise levels and then uses the curvature data to construct seed regions around each vertex. If a seed region meets certain criteria, it is assigned a region number and is grown into a set of connected vertices approximated by a bicubic polynomial surface. All the vertices in a region are within known distance and surface normal tolerances from their underlying surface approximations. The algorithm works on noisy or smooth data and requires little or no user interaction. We demonstrate the effectiveness of the segmentation on real-world examples.

Online Church

The growing numbers of online religion practice has increased significantly. This growing number is not only based on the website pattern, but also in the 3D online virtual environment. Over the last three years the practice of online churchgoing in the 3D virtual environment has grown rapidly through the arrival of a number of large, well-financed projects supported by well-known real-world Christian groups. This phenomenon has been allowing users not only just participate but also experiencing the online virtual environment. What are the users’ experiences in the virtual church? How does this experience relate to users’ spiritual life? These issues will be discussed in this chapter, starting with origin of online church. This is followed by the description of the one year study result based on participant observation and interview with the participants. The ability of Second Life as user generated virtual environment to act as medium of ritual practice and kinds of experience fostered will be interesting in the future development of the online church. The empirical based study may contribute greatly to a more nuanced and balanced understanding.

And Training

The technological growth in the last years have conducted to the development of virtual reality (VR) systems able to immerse the user into a three-dimensional (3D) virtual environment where the user can interact in real time with virtual objects. This interaction is mainly based on visualizing the virtual environment and objects. However, with the recent beginning of haptic systems, the interaction with the virtual world has been extended to also feel, touch and manipulate virtual objects. Virtual reality has been successfully used in the development of applications in different scientific areas ranging from basic sciences, social science, education and entertainment. On the other hand, the use of haptics has increased in the last decade in domains from sciences and engineering to art and entertainment. Despite many developments, there is still relatively little knowledge about the confluence of software, enabling hardware, visual and haptic representations, to enable the conditions that best provide for an immersive sensory environment to convey information about a particular subject domain. In this paper, the state of the art of the research work regarding virtual reality and haptic technologies carried out by the authors in the last years is presented. The aim is to evidence the potential use of these technologies to develop usable systems for analysis and simulation in different areas of knowledge. The development of three different systems in the areas of engineering, medicine and art is presented. In the area of engineering, a system for the planning, evaluation and training of assembly and manufacturing tasks has been developed. The system, named as HAMS (Haptic Assembly and Manufacturing System), is able to simulate assembly tasks of complex components with force feedback provided by the haptic device. On the other hand, in the area of medicine, a surgical simulator for planning and training orthognathic surgeries has been developed. The system, named as VOSS (Virtual Osteotomy Simulator System), allows the realization of virtual osteotomies with force feedback. Finally, in the area of art, an interactive cinema system for blind people has been developed. The system is able to play a 3D virtual movie for the blind user to listen to and touch by means of the haptic device. The development of these applications and the results obtained from these developments are presented and discussed in this paper.

Current computer and display technology allows the creation of virtual environment scenes that can be utilized for treating a variety of psychological disorders. This case study demonstrates the effectiveness of virtual environment desensitization (VED) in the treatment of a subject who suffered from fear of flying, a disorder that affects a large number of people. The subject, accompanied by a virtual therapist, was placed in the cockpit of a virtual helicopter and flown over a simulated city for five sessions. The VED treatment resulted in both a significant reduction of anxiety symptoms and the ability to face the phobic situations in the real world.

Constant Comparative Method

Past research on the effects of computer-mediated communication (CMC) on identity has focused either on the inherent risks or opportunities it provides. The authors argue that the paradox within the nature of CMC has led to paradoxical predictions about the effects of CMC on identity. Rather than adopting a naïve perspective focusing on only one side of the paradox, the authors take a view of technological realism in which the paradox is embraced. Guided by these views, the authors analyze 59 students’ papers reflecting on their identity choices in the creation and development of a Second Life avatar. Second Life is a three-dimensional (3D) multi-user virtual environment (MUVE) in which users create avatars (called “residents”) to explore, interact with other residents, learn, recreate, and shop with the local currency (i.e., Linden Dollars; http://secondlife.com/whatis/). Using the constant comparative method for thematic content, themes supporting a paradox of CMC effects on identity are identified from the student papers. The implications of a view of technological realism are offered.
