Future of Augmented Reality

Today virtual reality is very popular, but it is used mostly for entertainment. In future augmented reality referred to as the integration of digital information with the user's environment in real time will be the most popular thing in the world. Referring to these definitions, unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on the top. By this way our life can become more interesting and informative. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulated information about the environment and its objects is overlaid in the real world

Calmness in Virtual Environments Enhance User’s Spatial Presence Experience

Presence has been described to be crucial in several virtual reality (VR) applications. Among the factors influencing presence, realistic virtual environment has been examined extensively from the angle of geometry-based virtual reality (GBVR) application. The visual of the applications has been manipulated by altering numerous technological characteristics or by adding more sensory information (such as touch and smell). However, realistic virtual environment in GBVR application often required complex programming and takes longer time to develop. As such GBVR application is not acceptable for the application that needs to have a collection of realistic panoramic virtual environments. An alternative solution for above statement is image-based virtual reality (IBVR) application. IBVR refers to photo-based images, stitched together to develop a realistic panoramic virtual environment. Based on this method, many realistic virtual environments can be created in much less time but with limited interaction function. Despite this limitation, realistic virtual environment in image-based virtual reality is expected to enhance user’s spatial presence experience, which is supported by spatial presence theoretical model. There a few levels in this theoretical model before the formation of spatial presence, and the most important part in this theoretical model is primary egocentric reference frames (PERF), adapting calmness to produce spatial presence experience. Thus, this chapter describes the summary on adapting calmness as PERF

Virtual Reality for Baseball Batting

Nowadays, researchers explore the applications of Virtual Reality in different aspects of people’s lives. A few studies of Virtual Reality focus on applications in sports training. In this research area, one of the most important benefits is that athletes can focus on the training of one specific skill at one time. This SURF project focuses on the development of the virtual reality environment by designing targeted training for baseball batters, with the goal to achieve sufficient realism as judged by the Purdue baseball coaches. With the Virtual Reality training, baseball batters can practice and perfect a specific skill without a real pitcher or the limitation of the weather. Targeted training includes recognition speed, determination if the ball hits the strike zone, and judgement of baseball path realized by Unity as game engine. The project involves simulating different baseball paths, adding difficulties by changing the ball’s color to fulfill the training need. Future work will collect data on Purdue baseball players and provide recommendations based on the comparison of accuracy and recognition time after a period of training. Ultimately, we will collect data on how Virtual Reality training impacts baseball team’s performance during the subsequent game season

Capillary Refill using Augmented Reality

Master's thesis in Computer scienceThe opportunities within augmented reality is growing. Augmented reality is a combination of the real and the virtual world in real time, and large companies like Microsoft and Google is now investing heavily in the technology. This thesis presents a solution for simulating a medical test called capillary refill, by using augmented reality. The simulation is performed with an augmented reality headset called HoloLens. The HoloLens will recognise a marker attached to an artificial hand. The marker is used to detect and keep tracking of the position and orientation of the hand. Then a virtual 3D hand will be rendered over the marker on the artificial hand. Inside the artificial hand there is a pressure sensor that will be used to detect when users are adding pressure to the index finger. The finger on the virtual 3D model will then change nail colour on user interaction, and thereby simulating capillary refill

Applying the Think-Aloud Method for Usability Analysis in the Peking Metagamelan Virtual Reality Learning Application

The rapid development of technology affects people’s lives, including education, and virtual reality is one of many digital learning media that can be useful for learning. Virtual reality allows users to interact with the environment through a virtual world. With this concept in mind, an application to support gamelan learning based on Virtual Reality was developed called Peking Metagamelan Virtual Reality. Peking is a gamelan instrument made of bronze with rectangular blades. This application needs to know the user’s opinion regarding its performance and usability in its development. Therefore, the Think-aloud method assisted in the usability analysis process in the VR Metagamelan Peking application. The Think-aloud approach helps to express what the user feels and thinks when using the application. The research process involved five respondents from various educational backgrounds and different experiences. Respondents were asked to work on several task scenarios that were ordered. During the task scenario, respondents were asked to convey their thoughts regarding the application they were trying. The results were then analyzed and produced some recommendations for further improvements to the VR Metagamelan Peking application. The recommendations included improving the application interface, adding several features, and reducing the character’s speed

Interacting with Acoustic Simulation and Fabrication

Incorporating accurate physics-based simulation into interactive design tools is challenging. However, adding the physics accurately becomes crucial to several emerging technologies. For example, in virtual/augmented reality (VR/AR) videos, the faithful reproduction of surrounding audios is required to bring the immersion to the next level. Similarly, as personal fabrication is made possible with accessible 3D printers, more intuitive tools that respect the physical constraints can help artists to prototype designs. One main hurdle is the sheer amount of computation complexity to accurately reproduce the real-world phenomena through physics-based simulation. In my thesis research, I develop interactive tools that implement efficient physics-based simulation algorithms for automatic optimization and intuitive user interaction.Comment: ACM UIST 2017 Doctoral Symposiu

VIRTUAL REALITY - SHOWS A NEW VISION FOR TOURISM AND HERITAGE

Observe the heritage, a monument, architecture or a sculpture and immediately receive useful additional information to interpret better. This is one of the promises of virtual reality technology. The concept of virtual reality is far from being a new concept. Many experiments on ways to overcome layers of information, in addition to the real world elements, in live observation, have been made over the past decade, exploring different types of use, in leisure and professional contexts. Improving the perception of reality, in contrast to virtual reality, offers other initiatives that replace the context of a simulated world, and the possibility of using an interactive way to manipulate it in a digitally way. Those are the latest achievements that have opened new evolution perspectives of virtual reality. The idea behind most computer applications is to improve the user interaction with the real world, adding information through the use of tools and techniques that were confined to the digital world. But those applications could be used on tourism orientation in cities and in the professional world, in diverse areas, as architecture in the BIM environment or interior design architecture, with the projection of elements like the furniture and could be visualized in the virtual space. The ability to draw, could verify and share new realities, that was already being exploited by companies, which add new layers of information to be used in their catalogs and products that literally transform the hybrid PC, tablets and smartphones customer in additional information sources, that lead to know better what is observed, but in tourism and heritage that virtual reality is being used more intensively. Virtual Reality could be a good way to travel and understand the touristic world
