Why use a 2-D cursor in a 3-D world? Computer cursors are going 3-D!

10.08.2015

University of Montreal researchers present new technology at SIGGRAPH 2015 Conference

Researchers at the University of Montreal have developed techniques that enable computer cursors to interact in 3D in single or multiuser, local or remote collaboration scenarios. The system, unveiled today at the SIGGRAPH 2015 Conference in Los Angeles, is not so much about turning Word into an IMAX experience as offering designers an opportunity to navigate through and modify their creations manipulating 3D objects with 3D interactions.

"Our new technology challenges the notion of what a cursor is and does," explained lead researcher Professor Tomás Dorta, of the university's School of Design. "The cursor becomes a drawing and controlling plane". The techniques we're unveiling today involves using a tablet to control the cursor, but as it does not necessarily rely on external tracking of the user's movements, eventually other devices could be used, such as smart phones or watches."

What does control plane mean? "We use a Butterfly-net analogy to explain how the cursor selects objects in space - the users simply sweep the 3D cursors through," Dorta said. "For the manipulations of objects, the users can use gestures and movements such as pinching and orientation."

The cursor is in fact being demonstrated within the researchers' Hyve-3D design system, a full scale immersive 3D environment that enables users to create drawings on hand-held tablets, which can then be manipulated on the tablets to create a 3D design within the space. As the designers are immersed in their work, for example designing a living room, they can test different furniture options according to the scale and even work on the interior detailing.

The immersive images are the result of an optical illusion created by a high-resolution projector, a specially designed 5m-diameter spherically concave fabric screen and a dome mirror projecting the image onto the screen. Specialized techniques render the 3D scene onto a spherical projection in real-time

Univalor, the university's technology commercialization unit, is supporting the market launch of the Hyve-3D system and the 3D cursor, via the startup Hybridlab Inc. Several patents are pending. "Beyond its utility for sketching, we believe the 3D cursor has applications in a wide range of fields, such as architectural design, medical imaging and of course computer games. This isn't a gimmicky rebirth of the cursor, it's about rethinking how humans interact with computers as part of the creative process," Dorta said.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...

Rice University researchers test 3-D carbon nanostructures' thermal transport abilities

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University...
