Multi-delta design enables lighter, more economical robotic arm

By - December 21, 2014 13 Pictures
The design of a standard robot arm is, more or less, a mechanized representation of an idealized human arm, replete with elbow and wrist joints. Such designs tend to be unwieldy in confined spaces, and unsuitable for many industrial production line processes. As a result, delta arms – a series of interconnected parallelograms which restrict movement to the X, Y or Z directions and do not rotate – have become popular for use in tight workspaces. But, when faced with a requirement for both flexibility and compactness, a design that incorporates the best of both types is required. That's where the double-delta robot comes in. Read More

New ultrasound research creates holographic objects that can be seen and felt

By - December 2, 2014 1 Picture
Haptic feedback has become a common feature of recent technology, but such systems usually rely on stimulation of parts of the user’s body via direct mechanical or acoustic vibration. A new technique being developed by researchers at the University of Bristol promises to change all of this by using projected ultrasound to directly create floating, 3D shapes that can be seen and felt in mid-air.

Touch-sensitive 3D maps guide the blind with spoken instructions

By - November 21, 2014 5 Pictures
Getting around unfamiliar public spaces can be tough even with all your senses, but if you can't see where you're going it's downright intimidating. A new multi-sensory model promises a brighter future, though, with 3D maps that give spoken directions and building information when touched. The technology comes courtesy of a collaboration between tactile-graphics company Touch Graphics and the University of Buffalo's Center for Inclusive Design and Environmental Access (IDeA Center), and while it was designed specifically to help visually-impaired people, it's also meant to show off the potential of tangible touch interfaces.

Fidelity Labs employs Oculus Rift for a 3D view of investing

By - November 20, 2014 3 Pictures
Fidelity Labs, the R&D think-tank within Boston-based financial services company Fidelity Investments, has unveiled a new way for investors to literally explore the investment landscape. With similarities to the popular SimCity urban planning game, its online StockCity program displays an investment portfolio in the form of a city skyline, with an option to go 3D using an Oculus Rift virtual reality headset.

QR codes could generate 3D images on phones – no internet required

By - November 14, 2014 3 Pictures
Whether they're on product packaging, promotional materials or in magazines, most QR codes do the same thing – when a smartphone scans them with its camera, they trigger that phone's web browser to navigate to a given website. In the near future, however, they may be used to securely display 3D images on the user's phone, without even involving the often-untrustworthy internet. Read More

3D mapping project to monitor changes in sunken Pearl Harbor ships

By - November 11, 2014 1 Picture
The observance in the United States this week of Veterans Day, a federal holiday honoring those who have served in the American military, holds special meaning for those who lost loved ones when Japan bombed Pearl Harbor in Hawaii during World War II. An underwater 3D imaging project is using modern technology to bring greater insights to this tragic historical event. Read More

BAE Systems using VR tech to design Royal Navy warships

By - November 7, 2014 3 Pictures
Like many endeavors, making warships is a matter of specialization, with the various parts of the project scattered about the country or even across the world. For the Royal Navy and its principal shipbuilder BAE systems, this means engineers in Glasgow, Portsmouth, and Bristol having to work together despite being hundreds of miles apart. BAE’s answer is a network of "visualization suites" that allow teams to meet in a virtual environment where they can build and test designs as full-scale 3D prototypes before sending them to the shipyards.

Energy-efficient 3D display maintains images without power

By - November 3, 2014 1 Picture
Liquid Crystal Displays (LCDs) are a common and increasingly pervasive method of displaying information for everything from watches to giant TV screens. Though, like most other displays, LCDs require electrical energy to constantly display an image. Researchers from the Hong Kong University of Science and Technology, however, have produced an ultra-thin LCD screen prototype that is not only capable of displaying images without continuous power, but in 3D as well.
