New Chrome Feature Tells You Which Tab Is Making Noise

googlechromebeta32250wide There has to be very few things more annoying than having 20 tabs open when suddenly one of them starts playing music, and you just don’t know which one it is. This of course sends you on a furious hunt for that stupid website that would dare run ads that play audio without your consent, which is an activity most often accompanied with a generous amount of swearing. Well, a new feature on Google Chrome can dramatically cut down on the time it takes to take care of business, by showing a small icon on the offending tab. You’ll be able to zoom in immediately, and shut that down before you have to start pulling your hair out.

Currently available on the Chrome 32 beta release, we expect the feature to be implemented on the next stable release.

Optical Illusion Friday: That Dancing Girl Finally Makes Sense

By David Ponce

You’ve probably seen the above girl in those stupid ads that ask you “Are you right brained or left brained?” Or some such idiocy. But most people had a really hard time seeing the illusion. The above interpretation makes that easier. Look at the girl on the right, then on the left and hopefully you’ll notice the middle one changing directions. It doesn’t always work, but when it does it’s pretty awesome.

Optical Illusion Friday: Rotating Reversals

By David Ponce

Look at the red dot. Then look at the green dot. Notice something? If your eyes are working right, you should notice the rotation of the rings change directions every time. This illusion uses the fact that vision is different at the fovea (the center of the retina and point of sharpest vision) and at the periphery. Here comes the science:

There are two sources of information.

The global motion rotates counter-clockwise; the internal motion rotates clockwise.

Your visual system has to “choose” how to perceive these conflicting sources of information. In other words, will perception be guided by the motion of the ovals? Or by the motion of the internal lines? Or by a combination of these two? Or will you be able to see both types of motion at the same time, while keeping their signals separate?

When you look directly at the one-ring display, you can discern both sources of information (the ring will spin one way, and the motion caused by the internal lines goes the other way). But when you look at this display peripherally, it becomes difficult to separate the two sources of information, and the internal motion drives the perceived direction of the ring.

We hypothesized that the machinery of the foveal visual system allows us to represent multiple features simultaneously, but this machinery is absent in the periphery. The peripheral visual system seems to mix up the features that are available in the scene.
