Disney Research Invents Tactile Rendering of 3D Features on Multi Touch Surfaces

Disney Research, the Disney division which is paid to research and create new technologies found how to create textile renderings of 3D features on multi touch devices - like your iPhone or iPad - which is exactly what was missing. Here is a Disney Research video explaining how it works and below more explanation in the press release.

Disney Research, Pittsburgh, Develops Algorithm For Rendering 3D Tactile Features on Touch Surfaces
Controlling Friction Forces on Fingertips Creates 3D Haptic Effects

A person sliding a finger across a topographic map displayed on a touch screen can feel the bumps and curves of hills and valleys, despite the screen’s smooth surface, with the aid of a novel algorithm created by Disney Research, Pittsburgh for tactile rendering of 3D features and textures.
By altering the friction encountered as a person’s fingertip glides across a surface, the Disney algorithm can create a perception of a 3D bump on a touch surface without having to physically move the surface. The method can be used to simulate the feel of a wide variety of objects and textures.
The algorithm is based on a discovery that when a person slides a finger over a real physical bump, the person perceives the bump largely because lateral friction forces stretch and compress skin on the sliding finger.
“Our brain perceives the 3D bump on a surface mostly from information that it receives via skin stretching,” said Ivan Poupyrev, who directs Disney Research, Pittsburgh’s Interaction Group. “Therefore, if we can artificially stretch skin on a finger as it slides on the touch screen, the brain will be fooled into thinking an actual physical bump is on a touch screen even though the touch surface is completely smooth”
Disney Research, Pittsburgh researchers will present their findings at the ACM Symposium on User Interface Software and Technology, Oct. 8-­‐11, in St Andrews, Scotland.
In their experiments, the Disney researchers used electro vibration to modulate the friction between the sliding finger and the touch surface with electrostatic forces. Researchers created and validated a psychophysical model that closely simulates friction forces perceived by the human finger when it slides over a real bump.
The model was then incorporated into an algorithm that dynamically modulates the frictional forces on a sliding finger so that they match the tactile properties of the visual content displayed on the touch screen along the finger’s path. A broad variety of visual artifacts thus can be dynamically enhanced with tactile feedback that adjusts as the visual display changes.
“The traditional approach to tactile feedback is to have a library of canned effects that are played back whenever a particular interaction occurs,” said Ali Israr, a Disney Research, Pittsburgh research engineer who was the research lead on the project. “This makes it difficult to create a tactile feedback for dynamic visual content, where the sizes and orientation of features constantly change. With our algorithm we do not have one or two effects, but a set of controls that make it possible to tune tactile effects to a specific visual artifact on the fly.”
“Touch interaction has become the standard for smartphones, tablets and even desktop computers, so designing algorithms that can convert the visual content into believable tactile sensations has immense potential for enriching the user experience,” Poupyrev said. “We believe our algorithm will make it possible to render rich tactile information over visual content and that this will lead to new applications for tactile displays.”

Tokyo 2020 Olympic Stadium Gorgeous Architecture by Zaha Hadid

You probably have heard that Tokyo won two days ago the organization of the 2020 Olympic Games. It's a great news indeed for Tokyo and the whole Japan and with the legendary know-how of the Japanese there is no doubt that not only there will be ready in time but also that the 2020 Olympic Games will be great.

A new Olympic stadium will be built for Tokyo 2020 and its architecture is absolutely  gorgeous. The stadium is  designed by the great architect Zaha Hadid, the first woman architect to have won the legendary Pritzker price in 2004 - the equivalent of the Nobel prize for architects. I suggest you have a look at these spectacular renderings as for sure this new stadium has a fascinating futuristic "Sci-Fi" design.

See you in Tokyo in 2020!

" Jobs " Movie First Trailer

Frankly, knowing that Ashton Kutcher was going to play Steve Jobs in a movie about Jobs life was not the best news of the year when i heard about it last year. Then a short clip was released and i thought it looked terrible, and i was not the only one as Steve Wozniak himself declared that it looked "so far from everything that really happened". And Woz knows what he's talking about as he was there with Steve during all these years of Apple's creation...

Then, today, the first theatrical trailer was released and i have to admit that the trailer does its job,  it looks less terrible than i expected. We'll see if the movie will be as good as the trailer is!

Would Star Trek Technology Be Possible In Real Life ?

Even if you're not a "Trekkie" you may have seen the new and excellent Star Trek Into Darkness movie and you're probably aware of some of the Star Trek tech like space warp drive, teleportation, etc... But would all this be possible to achieve in real life, knowing what the real science tell us?

The Infographic picture below posted by the excellent will give you the answer!

Fundawear, The " Innovention " You Didn't Expect

From mapping the human brain to 3D printing "nothing stops the progress" as they say, but sometime innovations can happen in the most unexpected sector  which is exactly the case of today's "innovention".

The research team at Durex - yes, the famous condom manufacturer - has created what they call "Fundawear", a long-distance iPhone app controlling underwear stimulator - no kidding. So, yes, now there is even "an app for that" and the "multitouch" smart phones screens really deserved to be called like this! That said, why not, and if this "Fundawear" works as well as they say it could be fun.

On the first video below "Durexperiment" team developers located in Australia explain you more about this new "Fundawear" which will be released first in Australia only. Fundawear price hasn't been announced yet.

On the second video a cute couple is experimenting Fundawear...

On this third video Billie Whitehouse, the fashion designer explain how she designed the underwear which needed to include the technology used in Fundawear.
