Maybe It’s Time To Use A 3-D Cursor In A 3-D world?
Researchers at the University of Montreal have developed a system that enables computer cursors to interact in 3-D in single or multiuser, local or remote collaboration scenarios.
And a mounted laptop, a high-resolution projector, a 5-m concave fabric screen with a mirror, a six-degrees-of-freedom (6DOF) tracking system with controllers and handheld tablets is all that is needed.
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.
The new system 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".
"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".
explained lead researcher Professor Tomás Dorta, of the university’s School of Design.
What Does Control Plane Mean?
"We use a Butterfly-net analogy to explain how the 3-D cursor selects objects in space that users can simply sweep the 3D cursors through".
"For the manipulations of objects, 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 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".
“Our new technology challenges the notion of what a cursor is and does,” said Tomás Dorta, of the university’s School of Design. “The cursor becomes a drawing and controlling plane".
Dorta explained and added that:
"The system doesn’t rely on tracking the users’ movements".
"Eventually devices, such as smartphones or watches, could be used as 3-D cursor".
