POO Virtual Machine
- A virtual machine (VM) is an environment, usually a program or operating system, which does not physically exist but is created within another environment. In this context, a VM is called a "guest" while the environment it runs within is called a "host." Virtual machines are often created to execute an instruction set different than that of the host environment. One host environment can often run multiple VMs at once. Because VMs are separated from the physical resources they use, the host environment is often able to dynamically assign those resources among them. A user interacting with a virtualized server can view the server as a physical machine, in the sense that the user would see access to machines resources like hard disks, RAM, processors and Ethernet connections. In fact, all of these machine resources are virtual. For instance, instead of accessing a real hard disk, the user is accessing a construct of the host environment. This construct then accesses the real disk to record the data.
"A running program is often referred to as a virtual machine - a machine that doesn't exist as a matter of actual physical reality. The virtual machine idea is itself one of the most elegant in the history of technology and is a crucial step in the evolution of ideas about software. To come up with it, scientists and technologists had to recognize that a computer running a program isn't merely a washer doing laundry. A washer is a washer whatever clothes you put inside, but when you put a new program in a computer, it becomes a new machine. . . The virtual machine: A way of understanding software that frees us to think of software design as machine design." -From David Gelernter's "Truth, Beauty, and the Virtual Machine," Discover Magazine, September 1997, p. 72.

Mistry demonstrates SixthSense
Some of the most exciting augmented-reality work is taking place in research labs at universities around the world. In February 2009, at the TED conference, Pattie Maes and Pranav Mistry presented their augmented-reality system, which they developed as part of MIT Media Lab's Fluid Interfaces Group. They call it SixthSense, and it relies on some basic components that are found in many augmented reality systems:
These components are strung together in a lanyardlike apparatus that the user wears around his neck. The user also wears four colored caps on the fingers, and these caps are used to manipulate the images that the projector emits.
SixthSense is remarkable because it uses these simple, off-the-shelf components that cost around $350. It is also notable because the projector essentially turns any surface into an interactive screen. Essentially, the device works by using the camera and mirror to examine the surrounding world, feeding that image to the phone (which processes the image, gathers GPS coordinates and pulls data from the Internet), and then projecting information from the projector onto the surface in front of the user, whether it's a wrist, a wall, or even a person. Because the user is wearing the camera on his chest, SixthSense will augment whatever he looks at; for example, if he picks up a can of soup in a grocery store, SixthSense can find and project onto the soup information about its ingredients, price, nutritional value -- even customer reviews.
By using his capped fingers -- Pattie Maes says even fingers with different colors of nail polish would work -- a user can perform actions on the projected information, which are then picked up by the camera and processed by the phone. If he wants to know more about that can of soup than is projected on it, he can use his fingers to interact with the projected image and learn about, say, competing brands. SixthSense can also recognize complex gestures -- draw a circle on your wrist and SixthSense projects a watch with the current time.
