Virtual Reality: Concepts and Technologies

In course

Description

This lecture introduces the field of Virtual Reality (VR) focusing on immersive real-time interaction concepts and technologies. The course aims to provide a background in human perception-action to ensure users can react realistically in virtual environments. Topics covered include VR concepts, immersion, presence, 3D interaction, haptic feedback, and full-body interaction. Hands-on sessions involve Unity 3D setup, Oculus Quest introduction, basic interaction with controllers, structuring interaction behavior, finger tracking, and locomotion design. The course includes a group project to build a 3D VR game using Unity 3D and Oculus Quest. Assessment includes an article study, a group project, and an online oral control on VR concepts.

Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry.

Immersion into virtual reality (VR) is a perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment. The name is a metaphoric use of the experience of submersion applied to representation, fiction or simulation.

Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.

Action-specific perception, or perception-action, is a psychological theory that people perceive their environment and events within it in terms of their ability to act. This theory hence suggests that a person's capability to carry out a particular task affects how they perceive the different aspects and methods involved in that task. For example, softball players who are hitting better see the ball as bigger. Tennis players see the ball as moving slower when they successfully return the ball.

The study of time perception or chronoception is a field within psychology, cognitive linguistics and neuroscience that refers to the subjective experience, or sense, of time, which is measured by someone's own perception of the duration of the indefinite and unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Though directly experiencing or understanding another person's perception of time is not possible, perception can be objectively studied and inferred through a number of scientific experiments.
