VR Codes
Andy Lippman and Grace Woo
VR Codes are dynamic data invisibly hidden in television and graphic displays. They allow the display to present simultaneously visual information in an unimpeded way, and real-time data to a camera. Our intention is to make social displays that many can use at once; using VR codes, users can draw data from a display and control its use on a mobile device. We think of VR Codes as analogous to QR codes for video, and envision a future where every display in the environment contains latent information embedded in VR codes.

Envision a world where inconspicuous and unobtrusive display surfaces act as general digital interfaces which transmit both words and pictures as well as machine-compatible data. They also encode relative orientation and positioning. Any display can be a transmitter and any phone can be a receiver. Further, data can be rendered invisibly on the screen.

VRCodes present the design, implementation and evaluation of a novel visible light-based communications architecture based on undetectable, embedded codes in a picture that are easily resolved by an inexpensive camera. The software-defined interface creates an interactive system in which any aspect of the signal processing can be dynamically modified to fit the changing hardware peripherals and well as the demands of desired human interaction.

This design of a visual environment that is rich in information for both people and their devices overcomes many of the limitations imposed by radio frequency (RF) interfaces. It is scalable, directional, and potentially high capacity. We demonstrate it through NewsFlash, a multi-screen set of images where each user’s phone is an informational magnifying glass that reads codes arranged around the images.

MIT camera uses lasers to capture images from around corners | VIDEO

It fires these lasers at a wall, which bounces them into a room. The beams then reflect off objects and people before re-emerging and striking a detector. The detector takes measurements every few picoseconds, or trillionths of a second.

The camera does this several times, bouncing light off several different spots on the wall to cover several angles.

The system then compares the time at which each light beam returns to the detector (and their angle), to piece together a picture of the room’s geometry. It’s a bit like ultrasound, or the way Microsoft’s Kinect uses a bunch of infrared dots to determine 3D shapes.

Researchers at the Massachusetts Institute of Technology have built a camera that can see around corners, by bouncing bursts of laser light off doors or walls.

The system works like a periscope. But instead of mirrors, it uses ordinary walls, doors or floors; instead of light, the camera is equipped with a femtosecond laser that emits bursts of light so short that their duration is measured in

quadrillionths of a second.

This Lamp is Controlled by an Android Phone

The french developer of the unnamed project wrote this about the Android controlled lamp of awesome (this is the translation):

The brightness is changed by a vertical scrolling, the saturation by a horizontal scrolling and color varies with the orientation of the phone. The phone used in the video is a HTC Wildfire S Android 2.3.3. The application works with WiFi or mobile network (provided that the lamp is accessible from a public IP address)

The orientation of the phone is detected by the built-in compass (magnetic field sensor 3-axis) parameters hue, saturation and brightness are converted to RGB and then sent via a TCP connection to the Fox board that controls the lamp.

The smartphone is now becoming the hub for everything important in our lives. Social connections, payment systems, and banking are all controlled by our phone. Heck, you can even control your thermostat with an iPhone.

While turning your lights on and off with a computer or app might not be a new idea, one guy made something completely awesome and unique using Android. By swiping around on the app, the lamp responds to it. Also, the orientation of your phone dictates the lighting as well. Leer más “This Lamp is Controlled by an Android Phone”

How To Create a Detailed Briefcase Icon in Photoshop


Follow this step by step guide to create a detailed briefcase icon in Photoshop. We’ll build the rough outline with basic shapes, then add depth and definition with various Photoshop layer styles such as Inner Glow and Stroke. To really bring the icon to life we’ll use real photographic textures to give a tactile leather feel to the icon.

Briefcase icon

The icon we’ll be building has that crisp digital appearance popular in icons on the web. The sharp lines really help define what the icon actually depicts, which is important when it’s used at small scales in a web design or web app. What really brings the icon to life is the subtle gradients and textures. These additions don’t stand out when viewing the icon at a whole, but without them the design would appear flat and lifeless. Let’s go through the step by step process of how it’s made in Photoshop.

Using Light, Intel Confirms Data Will Be Sent Wayyy Faster in the Near Future

Intel announced a prototype technology today capable of moving data at 50 Gbps, comparable to sending an entire HD movie in one second – foreshadowing faster, longer data connections that could be revolutionary for consumers and data center users.

The prototype represents an important advance in Intel’s research into silicon photonics – using lasers instead of electrons to send data – which the company has been working on for years. Intel hopes to scale up the technology until it reaches speeds close to a terabit per second – fast enough to transfer a copy of the entire contents of a typical laptop in one second, the company said.

Data transmission speeds over wire-based connections are limited by bandwidth and distance. Intel turned to silicon-based photonic devices in order to transcend these physical limitations and continue to make more powerful chips.

With the new process, electrical signals are translated into light at different-colored wavelengths, which are combined and travel down a single fiber. Then the light is separated back into wavelengths and converted back to electrons. The speeds are so high that processors, memory and other computer components will no longer need to be placed inches from each other, implying vastly different computer designs in the future, the company said.

Anatomy of Colors in Web Design: Black – A Representation of Style & Mystery

This series Anatomy of Colors in Web Design is back! One color at a time, we look at web designs from around the world. Over the past few months, in the series, we’ve looked at various colors like Green, Blue and Yellow. Our fourth installment of the series will look at the darkest end of the spectrum of colors – Black.

Everyone has played with color paints or crayons when they were a child. Remember experimenting with various color paints only to realize that the more colors you add the darker the color becomes. Eventually, the paint becomes so dark that it resembles a black or dark brown shade of paint. Black; is it a color or is it an absence of color? Or maybe it is an overdose of color? After all, a scientist would say that black absorbs all the colors of the visible spectrum and reflects none of them to one’s eyes. Today’s exploration of black, the color of space and the universe, will take a look at how the color has impacted our lives.
Definition of Black

Black is the color that does not emit or reflect light in any part of the visible spectrum. It absorbs all frequencies of light. Hence black is often considered as the lack of all colors of light, or an exhaustive combination of multiple colors of pigment. Although black is sometimes described as “achromatic” or hue-less, in practice, it can be considered a color.

Black is the visual impression experienced when no visible light reaches the eye. This is in contrast with whiteness which is the impression of any combination of colors of light that equally stimulates all three types of color-sensitive visual receptors.

Pigments that absorb light rather than reflect it back to the eye appears to look black. However, a black pigment can result from a combination of several pigments that collectively absorbs all colors. Like the above mention of the childhood paints experiment, if appropriate proportions of three primary pigments are mixed, the result reflects so little light that it appears to be black. This provides two superficially opposite but actually complementary descriptions of black.

Black is real sensation, even if it is produced by entire absence of light. The sensation of black is distinctly different from the lack of all sensation. – Hermann von Helmholz

The Benefits of Black

Black is stern and formal. It is also authoritative and powerful. It is a color that can evoke strong emotions but it can also be overwhelming when used in excess. Dark colors make a room seem smaller, black being the epitome of darkness is no exception. Even a well lit room would seem dark when a lot of black is used.
