Virtual realityComputer-simulated experienceResearchers with the European Space Agency in Darmstadt, Germany, equipped with a VR headset and motion controllers, demonstrating how astronauts might use virtual reality in the future to train to extinguish a fire inside a lunar habitatVirtual reality (VR) is a simulated experience that employs 3D head-mounted displays and pose tracking to give the user an immersive feel of a virtual world.
3D human–computer interaction3D human-computer interaction devices: A volumetric 3D display (left) and a 3D input device (right)Virtual Fixtures, a system for 3D human-computer interaction.3D human–computer interaction refers to types of human–computer interaction where users are able to move and perform interaction in 3D space. Both the user and the computer process information where the physical position of elements in 3D space is relevant. It encompasses virtual reality and augmented reality.
Head-mounted displayBritish Army Reserve soldier wearing a Samsung Gear VR virtual reality headsetA head-mounted display (HMD) is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD). HMDs have many uses including gaming, aviation, engineering, and medicine. Virtual reality headsets are a type of HMD that track 3D position and rotation to provide a virtual environment to the user.
Immersion (virtual reality)In virtual reality (VR), immersion is the 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. EtymologyThe name is a metaphoric use of the experience of applied to representation, fiction or simulation.
Virtual fixtureA virtual fixture is an overlay of augmented sensory information upon a user's perception of a real environment in order to improve human performance in both direct and remotely manipulated tasks. Developed in the early 1990s by Louis Rosenberg at the U.S. Air Force Research Laboratory (AFRL), Virtual Fixtures was a pioneering platform in virtual reality and augmented reality technologies.
3D computer graphics3D computer graphics, sometimes called 3D computer-generated imagery (3D-CGI), refers to computer graphics that use a three-dimensional (3D) representation of geometric data (often Cartesian) stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an animation) or displayed in real time.Modality (human–computer interaction)In the context of human–computer interaction, a modality is the classification of a single independent channel of input/output between a computer and a human. Such channels may differ based on sensory nature (e.g., visual vs. auditory), or other significant differences in processing (e.g., text vs. image). A system is designated unimodal if it has only one modality implemented, and multimodal if it has more than one.
Somatosensory systemNerve system for sensing touch, temperature, body position, and pain Touch is a crucial means of receiving information. This photo shows tactile markings identifying stairs for visually impaired people. The somatosensory system, or somatic sensory system, is a subset of the sensory nervous system.
Haptic perceptionHaptic perception (Greek: haptόs "palpable", haptikόs "suitable for touch") means literally the ability "to grasp something", and is also known as stereognosis. Perception in this case is achieved through the active exploration of surfaces and objects by a moving subject, as opposed to passive contact by a static subject during tactile perception. Haptic perception involves the cutaneous receptors of touch, and proprioceptors that sense movement and body position.
Visual systemThe visual system is the physiological basis of visual perception (the ability to detect and processlight). The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment. The visual system is associated with the eye and functionally divided into the optical system (including cornea and lens) and the neural system (including the retina and visual cortex).
Armstrong LaboratoryArmstrong Laboratory was a research and development organization operated by the United States Air ForceMateriel Command. In 1997, the Laboratory was merged into the Air Force Research Laboratory. The Laboratory was named after Gen Harry G. Armstrong, known as "the father of space medicine."
HearingHearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. The academic field concerned with hearing is auditory science. Sound may be heard through solid, liquid, or gaseous matter. It is one of the traditional five senses. Partial or total inability to hear is called hearing loss.*As an Amazon Associate I earn from qualifying purchases.
