How Virtual Reality Works

How Virtual Reality Works

Monday, January 4, 2016 / No Comments

What do you think of when you hear the words virtual reality(VR)? Do you imagine someone wearing a clunky helmet attached to a computer with a thick cable? Do visions of crudely rendered pterodactyls haunt you? Do you think of Neo and Morpheus traipsing about the Matrix? Or do you wince at the term, wishing it would just go away?

Today, most VE systems are powered by normal personal computers. PCs are sophisticated enough to develop and run the software necessary to create virtual environments. Graphics are usually handled by powerful graphics cards originally designed with the video gaming community in mind. The same video card that lets you play World of Warcraft is probably powering the graphics for an advanced virtual environment.

A data suit to provide user
input

VE systems need a way to display images to a user. Many systems use HMDs, which are headsets that contain two monitors, one for each eye. The images create a stereoscopic effect, giving the illusion of depth. Early HMDs used cathode ray tube (CRT) monitors, which were bulky but provided good resolution and quality, or liquid crystal display (LCD) monitors, which were much cheaper but were unable to compete with the quality of CRT displays. Today, LCD displays are much more advanced, with improved resolution and color saturation, and have become more common than CRT monitors.

Other VE systems project images on the walls, floor and ceiling of a room and are called Cave Automatic Virtual Environments (CAVE). The University of Illinois-Chicago designed the first CAVE display, using a rear projection technique to display images on the walls, floor and ceiling of a small room. Users can move around in a CAVE display, wearing special glasses to complete the illusion of moving through a virtual environment. CAVE displays give users a much wider field of view, which helps in immersion. They also allow a group of people to share the experience at the same time (though the display would track only one user’s point of view, meaning others in the room would be passive observers). CAVE displays are very expensive and require more space than other systems.

Closely related to display technology are tracking systems. Tracking systems analyze the orientation of a user’s point of view so that the computer system sends the right images to the visual display. Most systems require a user to be tethered with cables to a processing unit, limiting the range of motions available to him. Tracker technology developments tend to lag behind other VR technologies because the market for such technology is mainly VR-focused. Without the demands of other disciplines or applications, there isn’t as much interest in developing new ways to track user movements and point of view.

Input devices are also important in VR systems. Currently, input devices range from controllers with two or three buttons to electronic gloves and voice recognition software. There is no standard control system across the discipline. VR scientists and engineers are continuously exploring ways to make user input as natural as possible to increase the sense of telepresence. Some of the more common forms of input devices are:

• Joysticks
• Force balls/tracking balls
• Controller wands
• Datagloves
• Voice recognition
• Motion trackers/bodysuits
• Treadmills

What is Augmented Reality?

Visualization of Augmented Reality

Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real world with a simulated one. Augmentation is conventionally in real-time and in semantic context with environmental elements, such as sports scores on TV during a match. 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 manipulable. Artificial information about the environment and its objects can be overlaid on the real world.

Thursday, January 1, 2015 / No Comments

!!!!!!!!HAPPY NEW YEAR(2015)!!!!!!!!  

Make your life interesting with new gadgets in new year. It's a good idea to collect and get detailed information about the gadgets. If you want to get knowledge about these technologies and gadgets then its a best place for you. In this website I post information for the visitors as need of current generation. In this article I include some useful gadgets of 2014.

Leap Motion

For decades, motion controls have held a persistent place in our visions of the future. Touchscreens are cool and all, but how about controlling your computer just by waving your hands through the air? Say what? Yes, the future is here — with the Leap Motion you can use a whole range of hand motions to point, wave, reach and grab at your digital interactions without having to touch a thing. Leap Motion may have a new lease on life thanks to inexpensive virtual reality headsets like the Oculus Rift. Leap Motion, the motion controller that lets you interact with a PC or Mac by waving your hands in midair, is rolling out the next generation of its software to developers. The update is aimed at creating a more intuitive user experience and will be the biggest for the platform since the company launched its gesture-based controller last year.

Parrot Drone 

It's neither a bird nor a plane. It's Parrot's new quadricopter Bebop Drone, and it's coming under your control. Its feather-weight ABS reinforced structure (400g) makes Parrot Bebop Drone robust and safe. Parrot Bebop Drone delivers the best performance: 8x times more powerful than Parrot AR.Drone 2.0 onboard computer, Bebop Drone navigation computer features a Parrot P7 dual-core CPU, quad-core GPU and 8 GB of Flash Memory. The Parrot AR.Drone 2.0 Quadricopter may not come with a weapons system, but strap some lasers on it and you'll scare the sh*t out of everyone in your hood. Control its 720p HD camera and four 28,500 rpm rotors with your tablet or smartphone both indoors and out, it has separate hulls for each.

Gerber Dime Micro Tool

We took the standard keychain multi-tool and made it better. In addition to stainless steel pliers, wire cutters, a fine edge blade, spring-loaded scissors, flathead screwdriver, crosshead driver, tweezers and file, the Dime includes a unique blade designed to safely cut and score plastic packaging and a bottle opener that is exposed even when the tool is closed. Compact and lightweight, the Dime is the most valuable change you'll find in your pocket. When you're in a pinch the Gerber Dime's ten various components will sure come in handy. Its sub 3-inch length when folded lets you easily keep it in your pocket and the always-exposed bottle opener is a convenient feature.

USB Missile Launcher "Thunder"

Until now your colleagues will have felt quite save at their office desks. The range of your previous USB Missile Launcher was limited. However, the engineers at Dream Cheeky did a few extra shifts to create a better version of this little office weapon. The newly developed USB Missile Launcher "Thunder" is capable of shooting up to 7.5 meters. No one is safe anymore! Position the USB Missile Launcher "Thunder" and slide on the missiles to load and fire - get ready for combat in no time! To operate download the Thunder software and install. The launch pad is controlled via mouse or keyboard. Left, right, up and down: your instructions will be followed to support missile accuracy. Optional sound effects will also provide real-life experience of firing missiles. The launcher it's a lot of fun, and even got it running on Linux with a few python scripts.

Spykee Wifi Spy Robot

Worried about people creeping in on your man cave while away on vacation? Leave Spykee the WiFi Spy Robot at home and you'll be able to actively record video, take pictures and control this little tank-treaded android from anywhere in the world. The smart little bugger even knows to go back to his home when his battery's low. The Spykee is a clever blend of things I’m familiar with and things that kids are familiar with. It combines practical and spatial skills with modern technology: internet, wireless control, voice reproduction, video-camera ‘eye’… that sort of thing. Spykee is marketed as a spy robot. Not in a military sense of course. This robot kit has a wireless webcam and it can be controlled remotely with your computer (either a PC or a Mac) using either an ad hoc wireless connection or a WiFi access point. Also, it is possible to control the robot through the internet. From the above mentioned you can understand that this can be a very educating toy. Theoretically, it could be used for more serious applications too. However, user feedback reveals some issues that could make such applications difficult.
