The Sword Of Damocles (virtual Reality)
The Sword of Damocles was the name for an early virtual reality (VR) head-mounted display and tracking system. It is widely considered to be the first augmented reality HMD system, although Morton Heilig had already created a stereoscopic head-mounted viewing apparatus without head tracking (known as "Stereoscopic-Television Apparatus for Individual Use" or "Telesphere Mask") earlier, patented in 1960. The Sword of Damocles was created in 1968 by computer scientist Ivan Sutherland with the help of his students Bob Sproull, Quintin Foster, and Danny Cohen. Before he began working toward what he termed "the ultimate display", Ivan Sutherland was already well respected for his accomplishments in computer graphics (see Sketchpad). At MIT's Lincoln Laboratory beginning in 1966, Sutherland and his colleagues performed what are widely believed to be the first experiments with head-mounted displays of different kinds. Features The device was primitive both in terms of user interfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Reality
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. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaze
In critical theory, sociology, and psychoanalysis, the gaze (French ''le regard''), in the philosophical and figurative sense, is an individual's (or a group's) awareness and perception of other individuals, other groups, or oneself. The concept and the social applications of the gaze have been defined and explained by existentialist and phenomenologist philosophers. Jean-Paul Sartre described the gaze (or "the look") in ''Being and Nothingness'' (1943). Michel Foucault, in '' Discipline and Punish: The Birth of the Prison'' (1975), developed the concept of the gaze to illustrate the dynamics of socio-political power relations and the social dynamics of society's mechanisms of discipline. Jacques Derrida, in ''The Animal that Therefore I Am (More to Come)'' (1997), elaborated upon the inter-species relations that exist among human beings and other animals, which are established by way of the gaze. Psychoanalysis In Lacanian psychoanalytic theory, Lacan's view on the gaze change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Environment
A virtual environment is a networked application that allows a user to interact with both the computing environment and the work of other users. Email Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant ..., chat, and web-based document sharing applications are all examples of virtual environments. Simply put, it is a networked common operating space. Once the fidelity of the virtual environment is such that it "creates a psychological state in which the individual perceives himself or herself as existing within the virtual environment" (Blascovich, 2002, p. 129) then the virtual environment (VE) has progressed into the realm of immersive virtual environments (IVEs).

Howard Rheingold
Howard Rheingold (born 1947) is an American critic, writer, and teacher, known for his specialties on the cultural, social and political implications of modern communication media such as the Internet, mobile telephony and virtual communities (a term he is credited with inventing). Biography Rheingold was born on July 7, 1947, in Phoenix, Arizona. He graduated from Reed College in Portland, Oregon, in 1968. His senior thesis was entitled ''What Life Can Compare with This? Sitting Alone at the Window, I Watch the Flowers Bloom, the Leaves Fall, the Seasons Come and Go''. A lifelong fascination with mind augmentation and its methods led Rheingold to the Institute of Noetic Sciences and Xerox PARC. There he worked on and wrote about the earliest personal computers. This led to his writing '' Tools for Thought'' in 1985, a history of the people behind the personal computer. Around that time he first logged on to The WELL – an influential early online community. He explored the exper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telepresence
Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance or effect of being present via telerobotics, at a place other than their true location. Telepresence requires that the users' senses interact with specific Stimulus (physiology), stimuli in order to provide the feeling of being in that other location. Additionally, users may be given the ability to affect the remote location. In this case, the user's position, movements, actions, voice, etc. may be sensed to Data transmission, transmit and duplicate in the remote location to bring about this effect. Therefore information may be traveling in both directions between the user and the remote location. A popular application is found in videotelephony, telepresence videoconferencing, the highest possible level of videotelephony. Telepresence via video deploys greater technical sophistication and improved fidelity of both sight and Sound recording and reproduction, s ...

Magnetic Tracking
Magnetic positioning is an IPS (Indoor positioning system) solution that takes advantage of the magnetic field anomalies typical of indoor settings by using them as distinctive place recognition signatures. The first citation of positioning based on magnetic anomaly can be traced back to military applications in 1970. The use of magnetic field anomalies for indoor positioning was instead first claimed in papers related to robotics in the early 2000. Most recent applications can employ magnetic sensor data from a smartphone used to wirelessly locate objects or people inside a building. There is currently no de facto standard for IPS, however magnetic positioning appears to be the most complete and cost effective. It offers accuracy without any hardware requirements and a relatively low total cost of ownership. According to Opus Research magnetic positioning will emerge as a “foundational” indoor location technology. Companies GiPStech Independent research brought in 2011 a ...

Philco
Philco (an acronym for Philadelphia Battery Company) is an American electronics industry, electronics manufacturer headquartered in Philadelphia. Philco was a pioneer in battery, radio, and television production. In 1961, the company was purchased by Ford Motor Company, Ford and, from 1966, renamed "Philco-Ford". Ford sold the company to GTE in 1974, and it was purchased by Philips in 1981. In North America, the Philco brand is currently owned by Philips. In other markets, the Philco International brand is owned by Electrolux. In the early 1920s, Philco made storage batteries, "socket power" battery eliminator units (plug-in transformers), and battery chargers. With the invention of the rectifier tube, which made it practical to power radios by electrical outlets, in 1928, Philco entered the radio business. They followed other radio makers such as RCA, Atwater-Kent, Zenith Electronics, Freshman Masterpiece, FADA Radio (Frank A. D'Andrea Radio), and AH Grebe into the battery-powere ...
