HCI : Virtual reality (AUGMENTED & MIXED REALITY)

Virtual reality (VR) is a computer technology that uses electronic devices to generate realistic images and sounds to simulate a user's physical presence in an artificial environment. The presenter discusses the history of VR from early prototypes in the 1960s to modern headsets from companies like Oculus Rift and HTC Vive. Various types of VR systems and devices are presented, as well as applications in fields like military, medicine, games, and movies. Both benefits and dangers of VR are outlined. Examples are given of how VR is used today in areas like overcoming fears, data visualization, training, real estate, sports, meetings, and storytelling.

This document discusses virtual reality and its types and applications. It defines virtual reality as a computer-generated immersive or wide field multi-sensory information which tracks users in real time. The main types discussed are immersive virtual reality, window on world virtual reality, and telepresence virtual reality. Applications mentioned include architecture, medicine, engineering and design, entertainment, training, and manufacturing. Advantages include creating realistic worlds and enabling experimentation, while disadvantages include high equipment costs and inability to fully replicate real world movement.

Augmented reality (AR) enhances the real world by adding virtual objects. It combines real and virtual aspects in real-time and is interactive in 3D. Early development began in the 1960s but the term "augmented reality" was coined in the 1990s. AR systems add virtual audio, objects, and other enhancements to the real world. Potential applications include medical, entertainment, education, and military uses. Continued research is needed to address performance, interaction, and alignment issues and to develop applications that provide instant information to users.

Virtual reality (VR) is an artificial environment simulated by computer hardware and software and presented to the user in such a way that it appears and feels like a real environment. Some key developments in VR history include Ivan Sutherland creating the first VR system in 1965, and the release of the film Tron in 1982, which was the first computer-generated movie. VR has applications in many fields including medical, gaming, education, and military. It provides advantages such as allowing students to learn concepts like astronomy or surgery in a simulated 3D environment. However, VR also has disadvantages like high costs and the technology still being in development.

Virtual reality is an artificial environment that is created with software and presented to the user through interactive devices. It involves immersing the senses in a 3D computer-generated world. The history of VR began in the 1950s with flight simulators for pilots. Major developments included research programs in the 1960s, commercial development in the 1980s, and the first commercial entertainment system in the early 1990s. There are different types of VR including immersive VR, augmented VR, video mapping, and desktop VR. Popular applications of VR include gaming, education, and training. The Oculus Rift is a virtual reality headset that provides an immersive stereoscopic 3D viewing experience.

Virtual reality uses technology to create simulated environments that users can interact with through headsets, gloves and other devices. It has applications in fields like medicine for surgical simulation and rehabilitation. After starting in the 1960s, VR has advanced with improvements in tracking, displays and immersion. The future holds potential for VR to replace computers and websites through fully immersive virtual worlds.

Virtual reality allows users to interact with simulated environments, whether based on real or imaginary places. Most VR is primarily a visual experience shown on screens or special displays, though some systems include sound and limited tactile feedback. While technical limitations currently make high-fidelity VR difficult, improvements in processing power, resolution and bandwidth are expected to overcome these issues over time. VR has applications in training, scientific visualization, medicine, education and more. Recent advancements include contact lenses and software that allow existing graphics applications to run on VR devices without source code access.

Augmented Reality connects the online and offline worlds. Let us have a look at what it is, why it is so popular and what are the businesses to which it can contribute. AUGMENTED REALITY CONNECTS THE ONLINE AND OFFLINE WORLDS.

Virtual reality (VR) creates a simulated environment that immerses the user. It works by tracking a user's movements and updating the virtual world accordingly. While early versions date back to the 1950s, commercial VR development began in the 1980s. VR can be non-immersive, augmented, or fully immersive. It has applications in gaming, business, education, engineering, medicine, and entertainment. Potential advantages include realistic training scenarios and innovative learning, while disadvantages include cost and reduced human interaction.
